Quality requirements of precision electronic stamping parts

In the stamping parts processing industry, there are various metal stamping products with different functions. Among them, precision electronic stamping parts have higher quality requirements. Because the requirements for electronic products are very high, electronic stamping parts factories also need to have very strict requirements for the processing and production of precision electronic stamping parts. The shape and dimensional accuracy of electronic stamping parts are more demanding. First of all, we will introduce the requirements for bent parts. 1. The shape of the bent part should be as symmetrical as possible, and the bending radius should not be less than the lower limit of the allowable bending radius of the material. 2. The curved side is too short to be formed, so the straight part of the curved side should be h:2δ. If h is required to be very short, you need to leave an appropriate margin to increase h, and then cut off the added metal after bending. 3. When bending parts with holes, avoid hole deformation. Secondly, the requirements for deep-drawn parts: 4. The shape of metal stamping parts should be simple, and the depth should not be too large. In order to reduce the number of drawing and easy formation; 5. The chamfering radius of metal stamping parts should not increase the processing procedures as much as possible, otherwise it will increase the number of drawing times and the number of dies, which is easy to produce waste and increase costs. Whether the mold used for metal stamping parts adopts an elastic ejector plate or a fixed ejector plate depends on the size of the ejection force, and the material thickness is the main consideration. As the elastic force of the elastic element used in the mold increases (for example, a rectangular spring is used), the ejection force of the elastic ejection plate is greatly improved. According to the current situation, when the material thickness is about 2mm or less, the elastic discharge plate is used, and when the material thickness is greater than 2mm, the fixed discharge plate is closer to reality. The thickness of the material stamped by this die is 1mm, so an elastic stripper can be used. [Related recommendation] Learn more: What are the methods for polishing the surface of stainless steel?
