What are the differences in the manufacture of stamping dies?

First, the manufacturing difference of stamping dies

1. Different smelting process

The smelting process of Dachang material is electric furnace smelting, out-of-furnace refining, and vacuum degassing. The chemical composition of the steel in this process is accurately controlled, the gas content in the steel is low, and the steel purity is high. The materials of small factories are generally mixed scrap and furnace materials in the intermediate frequency furnace, and the flat steel ingots are directly poured. The chemical composition deviation of this process is large, the impurities in the steel are large, and the gas content is high, resulting in more shrinkage cavities and internal cracks in the finished product, which seriously affects the processing performance of the steel.

2. The rolling process is different

Dachang’s steel ingots are forged into billets and then rolled into products. During the rolling process, multiple rolling mills and multiple deformations are used for continuous rolling. Small mills are steel ingots that are directly rolled back and forth by a single rolling mill. The ingot deformation is small, the rolling ratio is small, the internal microstructure is uneven, and the non-metallic inclusion particles are large. It is directly manifested as the local “saw and drill” of the material.

3. Different appearance quality

Since the material of the big factory is continuously rolled, and the number of deformations is large, the precision of its appearance and size is high, and the two sides are approximately right angles. Because the production process of the small factory material is all controlled manually, its appearance size deviation is large, the thickness and width tolerance is large, the flat steel fillet is large, and the cross-section deviates from the rectangle.

4. Different heat treatment methods for finished products

After the material of the big factory is finished, the global annealing process is adopted to ensure that the carbide grade in the steel is not greater than grade 4, and the uniformity of hardness is ensured. Small factory materials adopt general softening annealing process, even natural cooling, which cannot guarantee the uniformity of carbide grade and hardness in steel.

5. The effect is different

Due to the different production processes, it directly affects the use effect of materials. First of all, the material size deviation of the small factory is large, and the straightness is relatively poor, resulting in a large enough machining allowance during processing, otherwise it cannot be processed. Secondly, due to the uneven hardness of materials in small factories, it is difficult to process and punch holes, and the processing efficiency is low. After processing, the workpiece is easily deformed, and even the mold is scrapped.

What are the maintenance methods of hardware drawing molds?

1. Maintenance method of metal drawing die

The punch of the metal drawing die is relatively less frequently repaired, and it is broken due to failure. Therefore, in order to ensure that the metal drawing die has sufficient rigidity, the die and the unloading plate should be guided by the small guide posts on the four fixed punch fixing plates to ensure the uniformity of the punch gap, and multiple small punch guides. , The discharge screw on the discharge plate should adopt the same height sleeve to ensure the smooth punching.

The bottom of the effective cutting edge of the concave die is completely hollowed out or vacuum adsorption is used to ensure smooth discharge of punching waste; in addition, the punch edge of the metal drawing die should be ground regularly to ensure its sharpness; when the metal drawing die is not in use , You should apply anti-rust oil to the working part in time, but it should be noted that when you use the hardware stretching mold next time, you should first clean it, and then use oil-absorbing paper to test the flushing until the oil is absorbed cleanly, otherwise it will affect the plating quality. When moving the metal drawing die, it should be light, steady and slow to avoid shock and severe vibration. When storing, there should be a fixed position to control the air humidity, and it should not be placed directly on the shelf or metal stretching die.

The above are the two brothers’ methods for the maintenance of metal stretching molds. Correct use and maintenance can not only guarantee the service life of the metal drawing die, but also the quality of the final product. Therefore, it is still very necessary. If you have any questions about the maintenance of metal drawing dies, you can consult our manufacturers!

What are the assembly steps of the stamping die?

1. Assembly steps of stamping die

1. Select the assembly reference parts. When assembling, first select the datum part. The principle of selecting the reference parts is determined according to the dependence of the main parts of the mold in the processing process. The main components that can be used as assembly reference components are punch, die, punch, guide plate and fixed plate.

2. Component assembly. Component assembly refers to the assembly work in which the mold connects two or more components into a component according to the specified technical requirements before assembly. Such as mold base assembly, punch, die, fixed plate assembly, unloading, assembly of various components of the thrust mechanism, etc. These parts should be assembled according to the function of each part to ensure the assembly accuracy of the entire stamping die.

3. Overall assembly. Final assembly is the process of combining parts and components into a complete stamping die. Before final assembly, the assembly reference parts should be selected and the assembly sequence of the upper and lower molds should be arranged.

4. Adjust the gap between the convex and concave die. When assembling the mold, the uniformity of the punch and die gap must be strictly controlled and adjusted. After adjusting the clearance, tighten the screws and pins.

The methods of adjusting the gap between convex and concave molds mainly include light transmission method, measurement method, gasket method, coating method, copper plating method, etc.

5. Inspection and debugging. After the stamping die is assembled. The assembly accuracy must be guaranteed, the specified technical requirements must be met, and the function of each part of the mold must be checked according to the technical conditions for mold acceptance. Die tryouts are carried out under actual production conditions, and adjustments and corrections are made according to the parts produced by the die. After the mold test is qualified, the mold processing and assembly are basically completed.

Why do metal stamping dies need to try out?

After stamping and producing qualified samples, the performance and forming conditions of the mold have mastered the methods and rules of the product parts during the stamping process, which provides a reliable process design basis for the mass production of the mold. In the production of cold stamping dies in metal stamping parts factory, it is difficult to accurately calculate the size and shape of the blank before the blank is deformed, such as deformation, stretching, forming, cold extrusion and other product parts with complex shapes or high precision requirements. In order to obtain more accurate blank shape dimensions and material standards, qualified parts can only be determined by repeatedly debugging the mold.

In die design and process design, it is difficult to determine some process dimensions by calculation methods, such as complex protrusions of deep drawing die, rounded corners of concave die, geometry and size of certain parts. The metal stamping parts factory must carry out test punching and trimming at the same time, and the shape and size of the parts can only be determined after the qualified parts are punched out. After debugging, the problems, debugging and solutions exposed in the process, mold design and manufacturing are fed back to the relevant design and process departments to provide reference for the next design and manufacturing, and improve the level of mold design and processing. The metal stamping parts factory verified the quality and precision of the mold through the mold test, which provided the basis for future production.

The above is why metal stamping dies need to be tested before use. I hope it helps you. If you want to know more about stamping die, you can also pay attention to our website, we will update the information of stamping die from time to time!

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.

How much do you know about the principle of stamping parts processing?

1. The principle of stamping processing

Stamping parts are actually the use of punches and dies to apply external forces to sheets, strips, pipes, and profiles to cause plastic deformation or separation, so as to obtain the required shape and size of the workpiece. The processing method, the obtained workpiece It’s stamping parts.

1. Stamping parts are made by stamping under the premise of low material consumption and small 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. The dimensional accuracy of the stamping parts is high, and the size of the stamping parts is uniform and the same as that of the die, and the interchangeability is good. The general assembly and use requirements are well met without further machining.

3. The surface quality of stamping parts is good, the appearance is smooth and beautiful, which provides convenient conditions for surface coating, electroplating, phosphating and other surface treatments.
