Metal Stamping Supplier - Things to Keep in Mind When Processing Stamped Parts

It is possible for stamping parts to be produced and processed with various problems, which results in multiple problems and affects their use. Our goal with this guide is to let everyone know what details are crucial in the production and processing of stamping parts in order to avoid problems based on our years of experience.

When manufacturing the stamping die, the design cannot be changed at will

The stamping die is a crucial component of metal stamping parts manufacturers. It allows the stamping products needed for production to be processed. When manufacturing the stamping die, the design of the stamping die cannot be changed at will. It must be processed according to the reviewed drawings.

 

The design structure of the die cannot be altered at will, nor can the number of parts of the die be increased or decreased. Debugging, however, can be made easier by trimming the clearance and changing the positioning mode of the original mold structure. It is possible to modify the external and internal dimensions of a convex or concave mold part after Zui without changing the dimensions. The spring-back angle of the bending die, the filet radius, and the drawing depth of the male and female dies of the drawing die can be debugged so that the parts meet the drawing requirements.

 

It is found during the adjustment that the design and structural design must be changed before qualified metal stamping. When this happens, the mold design department should be contacted with the reasons for the change as well as the design change scheme. As soon as the scheme has been approved, it must be modified together, and then the revised design drawing must be redrawn. By changing the base drawing of the design drawing, the qualified stamping dies can be accurately used and manufactured during the next casting.

Small hole punching precautions during stamping

The microhole processing method that was previously used has gradually been replaced by the Metal Stamping Supplier process as a result of the development of science and technology and society. The punch strength can be improved by making it firm and stable. Fractures can be prevented, and the blank's stress state during punch can be adjusted. Since the punch diameter is tiny, if the standard method is used for punching small holes in stamping parts, the tiny punch is easy to break, so try to improve the punch strength to prevent it from cracking and bending.

 

Punching a hole plate involves extruding the material into the punch, not shearing it. The punching process is not a shearing process, but an extruding process. A portion of punched waste is compressed and squeezed into the surrounding area of the hole at the beginning of extrusion, so the thickness of punched waste is usually less than the thickness of raw material.

When using aluminum alloy as a mold, what should you keep in mind?

It is recommended that the stamping process be arranged as late as possible, provided that the process is not affected. For dies with many punch holes, one process can be added, and the punching process can be arranged last. Aluminum's hardness is relatively soft, and it is easy to block the mold.

 

A gap of 10% of the material thickness should be reserved on both sides of the mold, the knife edge should have a straight depth of 2mm, and the taper should be between 0.8 and 1 degree when designing the mold gap. As aluminum raw material is prone to producing aluminum chips during bending, PE film should be applied to it during bending in the stamping plant, causing damage, such as indentation and point damage, to the work piece. Aluminum alloy work piece cutting edges must be processed by slow wire cutting to prevent burrs and uneven blanking. PE film can help reduce the deterioration of the work piece.

Stamping parts for automotive applications: design considerations

The metal stamping parts used in automotive manufacture are called automotive stamping parts. They include brackets, spring seats, spring brackets, end caps, seals, compression valve covers/valve sleeves, etc. The production of products must meet the requirements of service performance and process performance and be more economical. There are some precautions to take when designing automobile stamping parts. Read more: www.tenral.com

 

Stamping parts manufacturers should use simple and reasonable structural shapes when designing automobile parts and reduce the number of processing surfaces and areas. In addition to meeting the technical requirements of product design, automobile stamping parts must meet the stamping process requirements of stamping parts processing plants as well as the cutting, electroplating, cleaning, and other processing requirements after stamping.
