Electronic stamping factory's quality requirements for metal stamping parts

Stamping parts processing plant, processing metal stamping parts, metal stamping parts, mechanical parts, etc. In the stamping parts processing industry, there are a variety of metal stamping products with different functions; used for internal precision electronic stamping such as mobile phone electronic parts The requirements of the quality of the products are higher; the electronic stamping parts factory has very strict requirements on the metal stamping parts processed and produced. The shape and size of the stamping parts: higher precision, first of all, the requirements for the bent parts: 1. The shape of the bent parts should be Try to be as symmetrical as possible, and the bending radius should not be less than the minimum bending radius allowed by the material. 2. 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. 3. When bending parts with holes, avoid deformation of the holes. Secondly, the requirements for deep drawing parts: 4. The shape of the metal stamping parts should be simple and the depth should not be too large. In order to minimize the number of drawing times and easy to form; 5. The fillet radius of the metal stamping parts should not increase the process procedure as much as possible, otherwise the drawing times will be increased, and the number of molds will be increased, and it is easy to produce waste and increase costs. Whether the die used in the metal stamping parts adopts an elastic pressure discharge plate or a fixed discharge plate depends on the size of the discharge force, and the material thickness is the main consideration. With the enhancement of the elastic force of the elastic element for the mold (such as the use of a rectangular spring), the discharge force of the elastic discharge plate is greatly enhanced. According to the current situation, when the material thickness is about 2mm or less, the elastic unloading plate is used, and the fixed unloading plate is closer to reality when the material thickness is greater than 2mm. The thickness of the material punched by this mold is 1mm, so elastic unloading plates can be used; article recommendation: a brief introduction to the process problems of stamping parts processing Previous post: a brief introduction to the process problems of stamping parts processing
