Characteristics Of Stamping Parts

Stamping Parts are mainly formed by stamping and stamping metal or non-metal sheets by means of press pressure. The main features are as follows:

(1) The stamping parts are manufactured by stamping under the premise of low material consumption. The parts are light in weight and good in stiffness, and after the sheet material is plastically deformed, the internal structure of the metal is improved, and the strength of the stamping parts is improved. .

(2) The stamping parts have high dimensional accuracy, uniform size with the same modular parts, and good interchangeability. General assembly and use requirements are met without further machining.

(3) In the stamping process, since the surface of the material is not damaged, it has a good surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment.

Tips to Remove the Auto Stamping Parts Glitch

In the process of metal stamping parts processing, sometimes the stamping parts have some burrs of different sizes, which have a certain impact on product quality. So how do we solve it? Auto Stamping Parts Exporter to tell you:

One: There are tools to remove the burrs of Auto Stamping Parts

Hole: Deburr the hole of Auto Stamping Parts using a chamfering knife or a large diameter drill bit.

Side: Use trowel, oil stone, sandpaper, whetstone. Outer diameter: The lathe angle is controlled during the metal stamping process. Second, manually remove the burrs on the Auto Stamping Parts

Electrochemical deburring: If the equipment is made, the cost is not high, economical, efficient, and useful.

Heat treated parts can also be debarred by shot peening and surface stress can be eliminated. Vibration grinding deburring (gear burn), high efficiency, quality can also be.

Notes on Stamping Die Assembly

First, the upper and lower die bases of the stamping die are installed. The upper mold base is mounted on the punch or press, and the lower mold base is mounted on the working surface of the punch or press. After the upper and lower mold bases are fixed, the mold parts can be mounted on the mold base to ensure the correct and accurate installation position, so as to avoid errors and the mold can not work normally. When installing the concave-convex mold, a uniform blanking gap is required to ensure the quality of the stamping and extend the service life of the stamping die. The assembly sequence of the upper and lower moulds should be determined according to the mould structure. Different installation methods are determined for mold installation with and without guide columns. For complex Stamping Mould installations, a reasonable assembly sequence is determined based on the size of the upper and lower mold parts. Sometimes the improper installation sequence not only affects the subsequent installation work, but also may not be installed, so the correct installation sequence is essential.

different types of Auto Stamping Parts?

Auto Stamping Parts, as the name suggests, are metal stampings that make up automotive parts. In automotive stamping parts, some of them are directly transformed into auto parts after being stamped, and the other part is subjected to welding, machining, or painting after being stamped to become auto parts. There are many kinds of automobile stamping parts, such as automobile shock absorber stamping spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil cartridges, lugs, brackets, etc. These are all automotive stampings.　In Auto Stamping Parts China, stamping is sometimes referred to as sheet forming, but with a slight difference. The term “sheet forming” refers to the use of sheet material, a thin-walled tube, a thin profile, or the like as raw material. The method of forming plastic work is collectively referred to as sheet forming, and at this time, deformation in the direction of the thick plate is generally not considered. First, the application range of metal stamping parts:

1. Special stamping enterprises. Such as the stamping of aviation parts, etc. belong to such enterprises, but these craft factories are also owned by some large factories.

2. Stamping of parts and components in the automotive industry. Mainly punching and forming. Many of the companies in this sector belong to scale factories, and there are also some independent stamping plants. At present, there are many such small factories near some automobile factories or tractor factories.

3The stamping factory of daily necessities. Do some crafts, tableware, etc. These factories have also grown significantly in recent years.

4. Stamping in the automotive industry. Mainly drawing. In this part of China, we mainly focus on large factories such as automobile factories, tractor factories, and aircraft manufacturers. Independent large scale stamping and deep drawing plants have not been seen.

5. Electric stamping plant. This type of factory is a new industry that has developed along with the development of electrical appliances, which are mainly concentrated in the south.

6. Household appliance parts stamping plant. These factories only emerged after the development of household appliances in China, and most of them are distributed to household appliances enterprises.

Second, the detection of metal stamping parts:

The hardness of metal stamping parts is measured by a Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes that cannot be tested on ordinary Rockwell benchtop hardness testers. Stamping parts processing includes punching, bending, drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloys. Plate, aluminum and aluminum alloy plates, etc.

Rockwell’s PHP series of portable surface hardness testers are ideal for testing the hardness of these stamped parts. Alloy stampings are commonly used in metal processing and mechanical manufacturing. Stamping is a process that uses a Stamping Mould to separate or form a metal strip. Its application range is very broad.

Metal Stamping Prevent Hidden Dangers

Metal stamping is dangerous, but it is not really dangerous. It complies with the stamping system and operates properly. Stamping is still very safe. During the Metal Stamping process, for safety reasons, pay attention to the adjustment screw of the slider, and do not let it extend too long. In the Metal Stamping process, in order to prevent the mold from moving, a layer of paper can be applied to the reinforcement, and the Stamping Mould is a dangerous situation. For the safety of metal stamping parts processing, disassemble the mold and wait until the machine is completely stopped. Metal Stamping processing, if you need to adjust and install the mold, you must first turn off the power into action. Although this can be done without turning off the power, the risk index will be greatly increased, so in order to be safe, the power must be completely turned off. Operate after stopping operation. In Metal Stamping processing, the presence of fastening screws will guarantee the safety of metal stamping parts processing. In order to ensure that this protection is not a hidden danger, it is necessary to tighten the fastening screws frequently to ensure that the fastening screws can have safety features.

Production Problems of Metal Stamping and Drawing Parts

Frequently Asked Questions About Metal Stamping Stretch Parts Production

1. The shape and size of the tensile parts do not correspond to the shape and size of the metal stamping tensile parts. The main reason is that bullets and positioning are not allowed. In addition to measures to reduce rebound, the reliability of blank positioning should be improved.

2. Metal stamping tensile parts surface strain is due to improper material selection, low heat treatment hardness, poor finish, concave corner wear, poor curved surface quality, excessive material thickness, unreasonable process options, lack of lubrication and other reasons.

3. Tensile bending crack

(1) When the angle between the bending line and the embossing direction of the sheet material does not conform to the specified arrangement, the bending line shall be perpendicular to the embossing direction when bending in a V-shaped unidirectional manner; when bending in both directions, the bending line and the embossing direction shall preferably be 45. degrees.

(2) The plastic material of the tensile member is poor.

(3) The bending radius is too small, and the pickling quality is poor.

(4) Insufficient lubrication – high friction.

(5) The fillet radius of the convex and concave mold is worn or the gap is too small – the feed resistance is increased.

(6) The quality of the black sheared and punched section is poor – burrs and cracks.

(7) The material thickness is seriously out of tolerance – difficult to feed

Solutions to problems with stretched parts:

1. The shape of the stretch forming process should be as simple and symmetrical as possible, and deep drawing as possible;

2. Stamping Bending Forming Parts that require multiple stretching, in response to the necessary appearance quality, respond to the presence of traces that can occur during the stretching process inside and outside the surface;

3. Under the premise of ensuring the installation requirements, the sidewall of the tensile member should have a certain inclination;

4. The spacing between the edge of the hole and the flange side of the flange should be appropriate.

Problems and SolutionThick Plate Stamping

As an Al Alloy Sheet Supplier, let’s talk about the main problems with thick plate stamping today.

(1) The stamping surface of Metal Stamping Connectors Parts is rough and even jagged. The size and shape accuracy of the punching piece is low, and the blanking has obvious arch bending deformation. The quality of stamping parts is low, which seriously affects the promotion and application of the process. How to improve the quality of thick plate punching is a key issue to be discussed urgently.

(2) The die has a low life, especially for punching hard steel or thick plates, and the die life is lower. This hinders the promotion of the process.

(3) There are still some problems to be further explored in the process, such as pre-processing and preparation of raw materials, including leveling, blanking, and spheroidizing annealing, cleaning, lubrication, and providing strips, sheets, and blocks. It is difficult for the general plant to be constrained by equipment conditions and the process is not mature.

(4) The determination of the stamping process and the design and manufacture of the die structure, including the selection of materials and heat treatment of die workpieces, remains to be explored.

(5) Research on the theory of thick plate stamping process has not yet been mentioned on the agenda. Such as: to improve the quality of thick plate blanking, reduce the effective measures of thick plate punching and punching pressure, reduce the noise of thick plate stamping and promote thick plate hot and clean punching technology, etc. must be specifically studied to guide factory practice.

Stamping Lids

With the development of society, stamping products have been popularized in all walks of life. It is very important to process stamping parts of good quality. In stamping processing, there will be many defects on the surface of the product. What is going on?

In the processing of stamping parts, problems such as impact lines, slip lines, collapse, hidden pits, surface distortion, etc. sometimes occur. For Aluminum Stamping Lids, defects on the outer surface are not allowed. ?

First, the impact line and the slip line are mainly due to surface scratches caused by friction at the stress concentration point after the sheet material and mold contact during the stamping process. Collapse, pit,

Second, the surface distortion is mainly due to insufficient deformation of the part, small local material strain, and defects that occur after the external force is released.

So how do we eliminate these defects?

1. Eliminate the impact line, you can change the stamping fillet, die fillet, increase the drawing depth, change the blank surface and other methods.

2. Eliminate the slip line, you can change the shape of the product (left-right symmetry), increase resistance and other methods.

3. To eliminate collapse and surface distortion, you should understand the level of stress gradient generated by the part in the deformation area, and try to ensure the uniformity of the plastic deformation of the product. At the same time, by increasing the resistance and improving the local shape and strain.

solutions after Metal Stamping deformation

In the process of metal stamping, we often encounter the deformation of stamping parts. So how to avoid the deformation of stamping parts when the deformation of metal stamping parts occurs?

Main factors of deformation and scrap of metal stamping parts:

1. Due to the long shock and vibration time, the fastening part is loose, the installation position of the stamping die has changed relatively, and the operator’s negligence has not been carried out in accordance with the operating procedures.

2. Improper installation adjustment and use of a die.

3. Poor quality of raw materials.

4. Clearance and reaction forces do not produce moments on the line. The main reason is that the gap between punch and death is too large. The concave edge of the die has an inverted cone or the contact area between the ejector and the workpiece. 1. In the structure of the stamping die, the pressure plate should be connected to the pressure plate in contact with a certain pressure.

2. Reasonable selection of blank clearance.

3. When the blanking part has a complex shape and there are multiple internal holes, if the cutting force increases unevenly, press the strip or use a high-precision press before blanking, the cutting force is uneven, and the blanking force is determined by the blanking The complex shape and multiple inner holes are added.

4. If the edge of the die is found to have a reverse taper, the edge of the die must be properly trimmed;

5. Regularly clean the stolen goods in the mold cavity, lubricate the surface of the metal plate, and there are oil and gas passage holes in the mold structure.

6. Flatten the paper before punching. If warping is still not eliminated, the punching workpiece can be leveled again by leveling the mold;

We know that the output of aluminum alloy stamping parts in China is very large. In addition to the huge demand for automobiles and other industries, we are constantly expanding the field of use. It is understood that at present, the scale of China’s IT industry is very large, especially the production capacity of the IT industry is very strong. Its various types of mobile phones and other equipment must not only meet domestic demand, but must also be exported to a large number of foreign countries.

As mentioned earlier, stamping parts have huge performance advantages in areas such as automotive engines, and have become indispensable metal die castings in these areas. These benefits have been applied to the IT industry. Our company also sells Al Alloy Stamping Plates. Welcome to consult.

design of convex and concave die for Metal Stamping parts

The basic principles of metal stamping cutting edge size calculation:

The dimensional accuracy of the blanking part is mainly determined by the dimensional accuracy of the die edge, and the fair gap value of the die also depends on the die edge size and manufacturing accuracy. Correctly determining the size of the die edge and manufacturing tolerances is one of the main tasks in designing a blanking die. It can be found in production practice:

1. Because there is a gap between the convex and concave dies, the falling material or punched holes are tapered, and the large end size of the blanking part is the die size, and the small end size of the punching part is the die size.

2. In measurement and use, the blanking part is based on the large end size, and the diameter of the punching hole is based on the small end size.

3. When punching, the convex and concave dies must be in friction with the blanking part of the waste.

As an Auto Stamping Exporter, the following principles must be taken into account when determining die edge size and manufacturing tolerances:

1. The size of the blanking part is determined by the size of the die, and the size of the hole when punching is determined by the size of the punch. Therefore, when designing the blanking die, the concave die is used as the reference, and clearance is taken on the convex die; when designing the punching die, the convex die is used as the reference, and clearance is taken on the concave die.

2. When determining die manufacturing tolerances, account should be taken of the part’s tolerances. If the precision of the cutting edge is too high (that is, the manufacturing tolerance is too small), it will make the mold difficult, increase the cost, and prolong the production cycle. Parts may diverge, which will reduce the life of the mold. The relationship between the precision of the parts and the precision of the mold manufacturing is shown in Table 2-1. If the parts are not marked with tolerances, the non-circular parts are processed according to the national standard “Non-fitting tolerance value” IT14 level, and the die can be manufactured according to IT11 level; for round parts, the mold can generally be manufactured according to IT7 ~ 6 levels. The dimensional tolerances of stamping parts shall be marked as one-way tolerances according to the principle of “entry body”. The deviation on the blanking part is zero and the lower deviation is negative; the upper deviation of the punching part is positive and the lower deviation is zero.

3. Considering the wear of the convex and concave die in punching, when designing the blanking die, the basic size of the concave die should be the smaller size of the dimensional tolerance range; when designing the punching die, the basic size of the convex die should take the workpiece hole size tolerance range. Larger size inside. In this way, when the convex and concave molds are worn to a certain extent, the qualified parts can still be punched out. Clearances of convex and concave die are taken as the least fair clearance values. Our company also has Aluminum Stamping Lids on sale. Welcome to consult.

Testing the hardness of metal stampings

As a Metal Stamping Door Clasp Shell Supplier, share with you. Metal stamping parts testing is divided into Metal Stamping testing and stamping die testing. Metal stamping parts are generally Rockwell hardness testers. Small, complex-shaped stampings can be used to test small planes, which cannot be detected on ordinary benchtop Rockwell hardness testers. The PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamped parts. Alloy stamping parts are the most commonly used parts in the field of metal processing and machinery manufacturing. Stamping is a processing method that uses a mold to separate or form metal sheets and strips. Its application range is very wide.Metal Stamping Door Clasp Shellfor

1. Hardness testing of metal stamping die

The main material of stamping die is dying steel (including tool steel and high speed steel), and sometimes carbide is also used.

Stamping molds usually require high hardness and abrasion resistance, and heat treatment is essential.

2.Hardness testing of metal stamping parts

The main purpose of hardness testing of stamping materials is to determine whether the degree of annealing of the purchased metal sheet is suitable for the subsequent stamping process. Different types of stamping process require different hardness levels of the board. The aluminum alloy plate used for stamping parts processing can be tested with a Vickers hardness tester. When the thickness of the material is greater than 13mm, it can be replaced with a Barcol hardness tester. A pure aluminum plate or a low-hardness aluminum alloy panel should be used.

In order to improve the technology of metal stamping parts, we must first analyze from its own characteristics. Metal stamping parts are thin and easy to form, and can be formed into parts of various shapes. With the application of welding, assembly, riveting and other processes, the product is given the possibility of achieving multiple structures.

1. When designing the structural shape of a metal stamping part, it is best to use a simple and reasonable surface and its combination. At the same time, the number of processing surfaces and the processing area should be minimized.

2. The selection of stamping oil should meet the process requirements. The stamping oil with excellent performance can significantly improve the processing environment and improve the accuracy of the workpiece.

3. Select the method of blank preparation in reasonable mechanical manufacturing, which can directly use profiles, casting, forging, stamping and welding. The selection of the blank is related to the specific production technical conditions, and generally depends on the production batch, material properties and processing possibilities.

How to ensure the continuity of aluminum casing stamping?

In the production process of aluminum casing, stamping is a very important process. However, with the continuous improvement of people’s requirements for aluminum casings, if the improvement of the production process is not enough to achieve the refined production of the stamping department, it is necessary to further improve the continuity in the production, so that the stamping department can be realized. At the same time of refined production, it can also effectively ensure product quality. So how should we ensure the continuity of aluminum casing stamping? The following editor will introduce to you:

The methods to ensure the continuity of the stamping of the aluminum casing are as follows:1. Make preparations for the stamping of the aluminum casing:

Carefully and carefully understand the structure and size of the product, check whether all aspects of the punch and die can operate normally, carefully hold a meeting to list and explain each element and step before stamping a new product, and consider the possible downtime factors during production.

2. Reduce the defects of aluminum casing during stamping:

Pay close attention to the phenomenon of waste products produced during production, analyze the reasons for the defective products, find out the root cause, and then summarize the methods to solve the problem completely.

3. Reduce or eliminate downtime when stamping aluminum casings:

Machine tools and molds are repaired as soon as there is a problem, that is, immediate repairs; operators and mold room masters maintain machine tools and molds every day, that is, routine repairs, such as using mold trial methods to predict potential failures and ensure production equipment. And machine tools will not be downtime due to failures, that is, preventive maintenance.

Selection of stamping process plan

A stamping part usually has many stamping process plans to choose from. If you want to choose a good scheme, you should consider all factors comprehensively, and then choose a suitable one that is more reasonable in technology and economy. Zhejiang Balford Precision Stamping Co., Ltd., a manufacturer with rich experience in stamping and precision stretching, come to talk about it.The best processing scheme for stamping parts is always relative; This is related to the specific production conditions of the stamping factory. Therefore, when determining the stamping process plan, we should start from the existing production conditions, ensure the quality of stamping products and meet the production batch requirements, and complete the stamping process in an economical and reasonable way.

In addition, for some combined stamping parts or stamping parts with special requirements, after analyzing the process nature, quantity sequence and process combination mode of stamping parts processing, non stamping auxiliary processes, such as drilling, turning and other mechanical processing processes, welding, riveting, heat treatment, surface treatment, cleaning and deburring, should also be considered.
