Metal stamping parts processing is the requirement of bending parts：
1.The shape of the bending part should be symmetrical as far as possible, and the bending radius should not be less than the minimum bending radius allowed by the material.
2.The curved edge is too short to form easily, so the straight part of the curved edge H> 2delta should be made. If H is required to be very short, a suitable margin should be set aside to increase H, bend well and then cut off the added metal.
3.When bending parts with holes, the deformation of holes should be avoided.Next is the requirement of deep drawing parts.
4.The shape of metal stamping parts should be simple and symmetrical, and the depth should not be too large. In order to minimize the number of deep drawing, easy to shape.
5.The fillet radius of metal stamping parts does not increase the technological process. Otherwise, it will increase the number of deep drawing and shaping work, increase the number of moulds, and easily produce waste products and increase costs.
Whether the die used for metal stamping parts is elastic pressure unloading plate or fixed unloading plate depends on the unloading force, and material thickness is the main factor to be considered. With the increase of elastic force of elastic components used in die (e.g. rectangular spring), the unloading force of elastic discharging plate is greatly enhanced. Hardware stamping is a method of forming and processing parts (stamping parts) with required shape and size by applying external force to sheets, strips, pipes and profiles by press and die to produce plastic deformation or separation.
