Precision stamping parts processing for shape and size control

by：Fortuna 2021-04-29

In the electronic hardware stamping parts factory, the production quality requirements for stamping are very strict. Therefore, we must strictly control the shape and size of stamping parts: 　　1. Requirements for bending parts: 　　1. The shape of the bending parts should be as symmetrical as possible, and the bending radius should not be less than the minimum bending radius allowed by the material.　　2, when bending parts with holes, in order to avoid the deformation of the hole 　　3, the curved edge is too short and it is not easy to form, so the straight part of the curved edge should be made H>2δ. If H is required to be very short, you need to leave a proper margin to increase H, and then cut off the added metal after bending.　　 2. Requirements for deep-drawn parts: 　　 1. The shape of the deep-drawn 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.　　2, the fillet radius of the deep-drawn parts without increasing the process procedures. Otherwise, it will inevitably increase the number of deep drawing and shaping work, but also increase the number of molds, and it is easy to produce waste and increase costs.
