How to reduce the possibility of damage to metal stamping parts?

1. How to reduce the damage of metal stamping parts

1. The model, specification and function of hardware accessories should conform to the current national scale and relevant regulations, and match the selection of plastic steel doors and windows.

2. For sliding windows with a width of more than 1 meter or doors and windows with double glazing, double pulleys or moving pulleys should be set.

3. The sliding brace hinge shall not use aluminum alloy material, but stainless steel material.

4. When installing hardware with fastening screws, there must be a metal lining plate inside, and the thickness of the lining plate should be at least twice the pitch of the fasteners. It must not be fastened to plastic profiles and must not be lined with non-metallic materials.

5. The hardware accessories should be finally installed, and the door and window locks, handles, etc. should be assembled after the door and window sashes are in the frame to ensure accurate positions and flexible switches.

6. Pay attention to maintenance after installation of metal stamping parts to prevent rust erosion. In daily use, lightly close and lightly open to prevent hard closing and hard opening, which may cause damage. No noise, now there are nylon wheels, which are not only noiseless, but also smoother, lighter, and have no shorter lifespan than the aforementioned pulleys. To make the doors and windows operate normally and smoothly, it is necessary to choose high-quality pulleys for the doors and windows. On the surface, the inferior pulleys have rough workmanship, no smoothness, and inflexible sliding.

How to effectively prevent punching noise

1. How to prevent stamping noise

1. Pay attention to the maintenance and cleaning of the mold, and keep the cutting edge sharp.

2. The shape, quantity, material and punching line of the die blade are longer. The contact surface between the die edge and the part should not be too large. The punch adopts inclined edge step punching, so that the cutting depth of the die at different positions is different, and the real cutting of the whole process is realized, rather than simultaneous extrusion.

3. The die edge must be perpendicular to the installation surface, and the matching clearance of the convex and concave die edges should be reasonable. When unloading is difficult, the lower die gap can be increased, the unloading force can be increased, and methods such as soft-surface unloading plates can be used.

4. The matching accuracy between the working templates and some exhaust grooves are processed.

5. The baffle is changed to small pieces, and the stripper and lower formwork are changed to inserts to reduce the attack area.

6. The source of the ejection top of the stripper plate is changed to a T-shaped ejector rod, the spring is installed on the upper die seat, and the equal-height sleeve is matched with the ejector rod to ensure that the stripper plate still has a certain degree of free movement when the mold is opened.

7. Maintain good lubrication, the mold is smooth, and there is no interference.

8. The aluminum plates on the surface of the upper and lower die bases are used for punching buffers.

9. After the mold is debugged, install a sound insulation cover or a sponge board on the punch for sound insulation.

10. Improve the precision of the punch press and reduce the structure noise. The buffering vibration damping and noise reduction oil cylinder is installed on the worktable, the helical teeth are lubricated, and the gear cover is installed in the pneumatic system.

What stamping oil is used for precision stamping parts?

Processing machinery parts, such as various stamping parts, sheet metal parts, welding parts, electronic devices, connectors, etc., with the development of social hardware products, so in the process of metal stamping processing, what is the selection principle of stamping oil products?

1. Silicon steel plate is a material that is easy to punch. Generally, to clean the workpiece, a low viscosity punching oil will be used to prevent punching burrs.

2. When selecting stamping oil for carbon steel plate, the best viscosity should be determined according to the difficulty of the process, the method of feeding the drawing oil and the degreasing.

3. Galvanized steel sheets will react chemically with chlorine-based additives, so when selecting stamping oil for galvanized steel sheets, attention should be paid to the possibility of white rust in chlorine-type stamping oil, and the use of Yida Borun sulfur-type stamping oil can avoid the occurrence of white rust. Rust problem, but should be degreased as soon as possible after stamping.

4. Stainless steel plate is a material that is prone to hardening, and requires the use of high oil film strength and anti-sintering tensile oil. Generally, stamping oil containing sulfur-chlorine compound additives is used to ensure extreme pressure performance while avoiding problems such as burrs and cracks in the workpiece.

5. Aluminum and aluminum alloy plates cannot use stamping oil containing chlorine and sulfur additives, preferably stamping oil with a neutral pH value.

The stamping oil suitable for the forming of thin plate parts of automobiles and motorcycles is a platen forming oil. It can also be used for the stretching and calendering of stainless steel parts. With the characteristics of high strength and high adhesion, single-type stamping and forming operations can be more effective. The surface finish and stretching effect of the workpiece are desirable and necessary oil for difficult mechanical stamping processing.

The stamping oil used in precision stamping parts plays a key role in the stamping process. Good cooling performance and extreme pressure and anti-wear performance have made a qualitative leap in the service life of the mold and the improvement of the accuracy of the workpiece. Depending on the material of the workpiece, the emphasis on the performance of stamping oil is also different.

The processing of electronic stamping parts is mainly to make metal or non-metallic sheets

The accuracy and surface state of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of cutting is less. Stamping is a production method that uses composite molds, especially multi-station-level molds, which can complete multiple stamping processes on a press to achieve automatic production from material uncoiling, leveling, cutting to forming, and finesse. The production efficiency is high, the labor conditions are good, and the production cost is low. Generally, hundreds of pieces can be produced per minute. Stamping is mainly classified according to the process, which can be divided into two categories: separation process and forming process. The separation process is also known as cutting, and its purpose is to separate the stamped parts from the sheet along the contour line to ensure the quality requirements of the separated section. The surface and internal properties of the stamping plate have a great influence on the quality of the stamped product, and the thickness of the precision stamping material is required to be accurate and uniform; the surface is smooth, no spots, no scars, no scratches, no surface cracks, etc. Uniform yield strength, no obvious direction; high uniform elongation; low yield ratio; low work hardening rate. According to the shape, precision and production volume of the part, the material is then cut in punching and budding, and the blank is placed on the scrap die.

The processing of precision stamping parts mainly uses metal or non-metallic plates through the pressure of the press to help the stamping die stamping and forming. What are its main characteristics? Let’s look further down.

1. Main features of precision stamping die processing

1. Precision stamping parts are made by stamping under the premise of low material consumption. Its parts are lightweight and rigid. After the plastic deformation of the plate, the internal structure of the metal is improved, and the strength of the stamping part is improved.

2. Precision stamping parts have high dimensional accuracy, the same mold parts have the same size, and have good interchangeability. No further machining is required to meet general assembly and use requirements. It should be facilitated to use existing equipment, process equipment and process flow as far as possible to process it.

3. In the process of stamping production, because the surface of the material is not damaged, it has a good surface quality, and the appearance of the parts is smooth and beautiful, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments.

2. Design principles of precision stamping parts

1. The design of stamping parts conforms to the use and technical performance of the product, and is easy to assemble and repair.

2. The design of stamping parts is conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. If possible, use low-cost materials and make parts as scrap-free as possible to reduce scrap.

3. The design of stamping parts is simple in shape and reasonable in structure, which is conducive to simplifying the mold structure and simplifying the number of processes, that is, to complete the processing of the entire part and reduce other methods, which is conducive to stamping operations, facilitates the organization of mechanized and automated production, and improves labor productivity.

4. Under the condition of ensuring normal use, the designed stamping parts and precision stamping parts should reduce the dimensional accuracy level and surface roughness level as much as possible, which is conducive to product exchange, reducing waste and ensuring product quality stability.

5. The designed stamping parts should be as beneficial as possible to the processing of existing equipment, process equipment and technological processes, and to prolong the service life of the stamping die. From car stringers, covers, etc.

What are the reasons for poor sheet metal processing?

In the actual production, the requirements for product quality are still rising, and the program matching the product is also improving. In the past, there were limited automatic expansion procedures. Only a few models can be expanded. Now basically all 3D The software can do the expansion effect. Why are there still defective products in such a situation? Let’s analyze the reasons for the defective products, taking the CNC punching machine as an example.

CNC punching machine sounds like a device for making precision parts. In fact, some of the samples made by CNC are defective. Most of the bad reasons are due to artificial blindness. Such as engineers, operating technicians operating NCT, and raw materials used.

The engineer’s fault is often caused by the habitual input of the thickness of a certain material, and the bending coefficient is related to the thickness of the plate; the operator’s error is also manifested in carelessness. After importing the product arranging table, it is necessary to adjust the coordinates of the parts. , the usual cause of failure is that incorrect coordinates are entered; and a material cannot be produced according to the actual thickness. It is also possible that materials are not used in accordance with the requirements of the drawings, such as smooth stainless steel, single-sand-surface stainless steel, double-sand-surface stainless steel, etc., one material is required, and other replacements are bad. It is not easy to make mistakes in the digital punching of sheet metal parts, and there are so many bad reasons. Most processes rely on precision equipment processing, and labor is only auxiliary work. This problem is a practical problem encountered by the editor in the realization of the NCT workshop, and I hope it can help readers.

What are the technical requirements for the custom processing of hardware chassis shells?

Not only that, but the chassis also needs to be resistant to vibration. Stamping resistance, corrosion resistance, dust-proof, waterproof, radiation-proof and other properties ensure the stable and reliable operation of the equipment.

2. With excellent performance and safety protection facilities, it is easy to operate, install and maintain, and ensure the safety of operators.

3. Strain in production, assembly, debugging and packaging and transportation.

4. It should meet the requirements of standardization, normalization and serialization.

5. Beautiful appearance. Applicable, color coordinated.

In the current era, the chassis has become an indispensable hardware product in the computer industry. Various styles of cabinets can be seen in major computer rooms. With the continuous development of today’s computer industry, the functions embodied by the cabinets are also getting bigger. Cabinets are generally used in network wiring rooms, floor wiring rooms, central computer rooms, data computer rooms, network cabinets, control centers, monitoring rooms, monitoring centers, etc.

2. What are the types of chassis shell materials?

The following Zhejiang Baifudu Electromechanical editor mainly introduces the common computer case materials for you. Let’s take a look!

1. Acrylic side through case

The transparency of the acrylic sheet is excellent, and the light transmittance of the colorless and transparent plexiglass sheet can reach 92%. In addition, the acrylic sheet also has flow weather resistance and strong adaptability to the natural environment. Long-term sunshine, wind and rain will not make it change. The acrylic side lens can see the use of the hardware inside the case. If the accessories inside the case have lighting effects, the color that comes out will be a different feeling.

2. Sound absorption and noise reduction chassis

The so-called active noise reduction is no longer blindly increasing the thickness of the board to passively and inefficiently block the noise, but adding high-density suction cotton to actively absorb the noise, eliminating a large part of the noise before it is transmitted to the chassis board, thereby enhancing the noise reduction effect. The material of the sound-absorbing cotton not only has a good sound-absorbing effect, but also has good heat dissipation. With several large-sized silent fans, it really kills two birds with one stone.

3. Glass side transparent case

Different from ordinary glass, tempered glass is generally used in the glass side see-through case, which forms compressive stress on the glass surface. When the glass is subjected to external force, it first offsets the surface stress, thereby improving the bearing capacity. Compared with ordinary acrylic and plastic side panels, the side panels made of tempered glass have stronger light transmittance, so after building a light pollution platform, the visual effect of tempered glass chassis is better, and the abrasion resistance of tempered glass is better. It should also be stronger than acrylic. After a period of use, it will not be scratched like acrylic, which will affect the appearance. In addition, due to the large weight of the tempered glass, it can effectively stabilize the body and prevent the chassis from resonating. Therefore, tempered glass is more and more popular with chassis manufacturers and DIY players.

4. Aluminum chassis

Aluminum chassis often have the characteristics of excellent heat dissipation, electromagnetic shielding, and light material. The chassis of this material is very textured whether you look at it or touch it, but the price of aluminum chassis is very expensive, and the appearance of the chassis is very high. Changes are also less. Compared with the steel plate, the strength of the aluminum plate is lower, especially the upper plate, the side plate, and the side plate that is not installed on the chassis. If you accidentally step on it, it will leave irreparable dents.

5. Plastic case

Compared with metal materials, one advantage of plastic materials is that shaping and coloring will be very simple, which increases the look and feel of the chassis. However, the quality is also clear. The plastic material not only has low strength and cannot absorb electromagnetic radiation, but also is more prone to scratches and difficult to maintain.

6. SECC chassis

SECC is electrolytic lead galvanized steel sheet. It is a stamping material, that is, a zinc layer is plated on the surface of the cold-rolled sheet, and the surface is smooth and gray. Anti-rust and corrosion-resistant, but the price is relatively high. The general plate thickness is between 0.4~3.2mm. SECC material is more common in big brand computer case manufacturers, and the price is more expensive than hot-dip galvanized sheet. So, we can see this material in high-end gaming cases or server cases.

What aspects should metal stamping parts processing plants pay attention to in the design?

Generally speaking, the process of producing auto parts in metal stamping parts processing plants includes: stamping, cleaning, welding, degreasing, cleaning, electrophoresis, etc.

1. When designing the structure and shape of auto parts, it is best to adopt a simple and reasonable structure, and at the same time minimize the number of machined surfaces and processing area.

2. The materials used in automotive metal stamping parts must not only meet the technical requirements of product design, but also meet the stamping process requirements of stamping parts processing plants, as well as the processing requirements of cutting, electroplating, cleaning and other processes after stamping.

3. In the forming process, in order to facilitate the improvement of stamping deformation and the quality of the parts, the material should have good plasticity, a large plate thickness direction coefficient, a small plate plane direction coefficient, and a small yield strength and elastic modulus ratio of the material. Regarding the separation process, the material does not need to have good plasticity, but it should have a certain plasticity. The better the plasticity of the material, the easier the separation will be.

What are the positioning benchmarks for stamping processing?

1. Principles of selection of fine benchmarks

1. The principle of datum coincidence: The design datum of the machined surface should be selected as the precise datum as much as possible, which can avoid the positioning error caused by the misalignment of the datum.

2. The principle of mutual reference: when the positional accuracy between the two machined surfaces on the workpiece is relatively high, the method of repeated machining of the two machined surfaces as a reference to each other can be used.

3. Self-base principle: some surface finishing processes require small and uniform machining allowances, and the machined surface itself is often used as the fine base.

4. Unified datum principle: as many surfaces as possible on the workpiece should be machined with the same set of fine datums as much as possible to ensure the relative positional accuracy between the machined surfaces.

The above four principles for selecting rough benchmarks can sometimes not be taken into account at the same time, so the main decision should be made.

2. Principles of selection of rough benchmarks

1. A rough benchmark should be used in one process of workpiece processing. Whether the rough benchmark is selected correctly or not is not only related to the processing of the first process, but also has a significant impact on the entire process of workpiece processing.

2. The principle of rationally allocating machining allowances: Considering ensuring that the machining allowances of important surfaces are uniform, important surfaces should be selected as rough benchmarks.

3. The principle that rough benchmarks should not be reused in general.

4. The principle of easy clamping: In order to stabilize the positioning of the workpiece and the clamping is reliable, the selected rough datum is required to be as smooth and clean as possible. Forging flashes, pouring riser cuts or other defects are not allowed, and there must be enough support area.

Design principles of precision stamping die structure

1. Design principles of precision die structure

1. According to the production batch of stamping parts, determine whether to use a simple die structure or a complex die structure. Generally speaking, a simple die structure has a short life and low cost, and a complex die structure has a long life and high cost. Therefore, if the number of stamping parts is small, it is more suitable to use a simple die structure. Larger quantities are more suitable for conventional die structures with longer service life.

2. The accuracy level of the stamping die is determined according to the size requirements of the stamping parts. If the dimensional accuracy and section quality of the stamping parts are high, the precision stamping structure should be used, and the stamping parts with general precision requirements can use the ordinary stamping structure.

3. Select the type of stamping die according to the capability of the existing equipment. For example, when drawing workpieces, a double-action die structure is much better than a single-action die structure.

4. The type of unloading device in the die structure is selected according to the thickness of the stamping plate. For example, when blanking thick plate workpieces, if the requirements for surface straightness and sharpness are not high, a fixed unloading device can be selected. Suitable for selection.

5. Select the mold type according to the technical conditions and economy of mold manufacturing. For example, when the technical requirements of die manufacturing are low, a simple die stamping structure should be designed as much as possible. When the variety of mold equipment is complete and the machining accuracy is high, in order to improve the service life of the mold and achieve mass production, a more complex precision mold stamping structure should be selected.

Designers should consider a variety of factors when choosing a die structure. Because simple stamping dies and general traditional stamping dies have their own advantages and limitations. This requires analysis and comparison to make the selected stamping die structure mode as reasonable and reliable as possible.

In addition, stamping parts also need to meet their unique anti-rust requirements: stamping parts circulating in the factory must ensure 15 days of anti-rust time.

The basic characteristics of stamping die processing

First, the basic characteristics of stamping die processing 1. The requirements for machining accuracy are relatively high. A pair of molds is generally composed of a punch and a die base. Of course, it may also be a multi-piece splicing module. Therefore, the combination of the upper and lower molds, the inserts and the cavity. […]

Resonant Rods RF Filters for 5G Technology

We explain how the new XBAR resonator technology is optimized to create filters for 5G and WiFi networks. “We are working with several RF module and filter suppliers for 4G and 5G filters and have recently achieved a major milestone that will lead to mass production of critical 5G RF filters,” said PAX.

The proliferation of 4G LTE networks, the deployment of new 5G networks, and the ubiquity of Wi-Fi have led to a dramatic increase in the number of radio frequency bands that smartphones and other mobile devices must support. RF filters are not new and our smartphones would not work without them. The first generation of smartphones had fewer than 10 filters because they didn’t have many RF signals. Today—using Wi-Fi, Bluetooth, GPS, and 2G, 3G, 4G, and now 5G—more than 100 filters are trying to prevent conflicting signals coming into your phone.

However, 5G networks are not ready for prime time. The challenge is that each 5G band must be isolated with filters to avoid interference that can drain battery life, reduce data rates, and cause dropped calls. Today, filter technology cannot deliver the performance these new networks promise.

We are now focusing on 5G communication accessories because the requirements have changed dramatically compared to 4G filters. If you look at the iPhone 13, there are nearly 100 sonic filters; in the iPhone 13, one filter is required for each frequency band that needs to be processed in the phone. As we look at 5G, higher frequencies, wider bandwidths and more complexities, it is clear that the market needs a different type of acoustic building blocks for these filters. That’s why we’ve developed technology to address new markets in the 5G and Wi-Fi bands 5 GHz and 6 GHz, and ultra-wideband (UWB) from 6 to 8 GHz.

The application range of metal stamping parts and the concept of stamping die

1. Application scope of metal stamping parts

Common application fields of metal stamping parts are:

1. Stamping in the automotive industry.

Mainly draw. In my country, this part is mainly concentrated in large factories such as automobile factories, tractor factories, and aircraft factories. There are few independent large-scale stamping and drawing factories. 2. Stamping of auto parts and other industries.

Mainly punching and shearing. Many companies in this sector are classified as standard parts factories, and there are also some independent stamping factories. At present, there are many such small factories near some automobile factories or tractor factories.

3. Electric device stamping factory. This type of factory is a new industry, developed with the development of electrical appliances, and the factories in this sector are mainly concentrated in the south.

4. Stamping factory for daily necessities. Making some handicrafts, tableware, etc., these factories have also developed greatly in recent years.

5. Home appliance parts stamping factory. These factories only appeared after the development of household appliances in my country, and most of them are distributed in household appliance enterprises.

6. Special stamping enterprises. For example, the stamping of aviation parts belongs to this type of enterprises, but these process factories are also classified as some large factories.

Second, what is stamping processing

Stamping is an advanced metal processing method. It is based on the plastic deformation of metal. Under normal temperature conditions, the die and stamping equipment are used to apply pressure to the sheet, so that the sheet is plastically deformed or separated, so as to obtain a Parts of a certain shape, size, and performance.

Three, the concept of stamping die

Stamping dies, also known as stamping dies, metal dies, and metal stamping dies, have almost the same meaning. It refers to the pressure processing method that uses a die fixed on a punch or a press to apply a certain pressure to a metal or non-metallic sheet to separate or form the material, thereby obtaining parts with certain size requirements and qualified appearance quality. There are many kinds of molds, and I mainly focus on the metal stamping molds that I am familiar with.

The products processed by the mold are basically the same in size and appearance, and there is no big difference. Because of the rapid prototyping, high production efficiency, stable product quality, high precision, high material utilization, simple operation and low labor intensity, the The technical requirements of the operators are not high. The average person only needs to come in and follow others to learn the operation for a day or two, and they will be able to get started very quickly. If you are a production line host, you must learn to operate punches, feeders, levelers, and mold removal. These are all very simple tasks, and you need to be strong and willing to bear hardships and stand hard work.
