What are the requirements of precision stamping for bent parts and deep-drawn parts

Precision stamping parts are widely used and can be seen everywhere in our daily lives. With the development of society and science and technology, people's needs and requirements are getting higher and higher, including the shape, dimensional accuracy, appearance, etc. of the stamping parts, then we must strictly control the production process . In this way, let's first understand what are the requirements for bent and drawn parts in the precision stamping process? Requirements for bending parts: 1. The shape of the bending parts should be as symmetrical as possible, and the bending radius should not be smaller than the smallest* bending radius allowed by the material. 2. When bending parts with holes, 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. Requirements for deep-drawn parts: 1. The shape of deep-drawn parts should be simple and symmetrical, and the depth should not be too large. In order to make the number of drawing less 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.
