Production quality requirements for metal stamping parts
Spring products such as metal stamping parts are very widely used products in our daily life. With the development of science and technology, people's requirements for metal stamping parts are getting higher and higher. Especially the requirements in terms of quality and technology are very high. 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: First of all, the requirements for bent parts:
1. The shape of the bending part 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 holes 3. The curved side is too short to be easily formed, so the straight part of the curved side 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. The second is the 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 drawing times and easy to form. 2. The fillet radius of the deep drawing part does not increase the process procedure. 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.
