Structural design of metal sheet metal stamping parts is of great significance, affecting the quality of stamping parts and the efficiency of stamping. Reasonable design can not only ensure the performance of finished products, but also play a very important role in reducing manufacturing costs, improving production efficiency, and improving product qualification rates.
Structural design of metal sheet metal stamping parts:
1. The shape of the stamping parts, including the bent and unfolded shapes, should be as simple and regular as possible, which not only reduces the difficulty of mold design but also minimizes waste during layout. Principles of simplification, uniformity, and symmetry.
2. The internal and external corners of the stamping parts should be designed as arc transitions as much as possible to avoid excessive sharp corners. There should be arc connections at the junctions of straight lines or curves. This is because sharp corners can easily cause chipping and excessive wear, and they can easily crack during heat treatment during subsequent further processing.
3. Choose a design that improves metal utilization, reduces the variety and specifications of materials, and reduces waste as much as possible.
4. When the requirements for dimensional accuracy level and surface roughness level can be appropriately reduced, they should be reduced as much as possible.
5. Set a reasonable edge distance between holes based on the strength of the tool mold and the quality of the blanking parts.
6. Adjust the stamping part gap taking into account the burr height and the bright strip condition of the cross section.
7. When selecting materials, the mechanical properties, formability, corrosion resistance, cost and other factors of the material should be comprehensively considered. For example, the material design of Deep groove ball bearing double-sided seal dust cover stamping parts usually chooses stainless steel and cold-rolled carbon steel tin steel plates.
8. The design of stamping parts should avoid long and narrow cantilevers and slots, that is, the depth and width of the protruding or recessed parts of the stamping parts should be designed reasonably.
Metal stamping parts are common metal processing parts. Structural design of metal sheet metal stamping parts directly affects the quality, cost and production efficiency of the product. Bearing accessories outer spherical bearing dust cover skeleton stamping parts that are common in life are also one of the metal stamping parts. When designing the structure of the stamping parts, we must also pay attention to the problems of sharp corners and arcs.
