Production quality requirements and design principles of precision metal stamping parts

Spring products such as precision metal stamping parts are very widely used products in our daily lives. 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 production quality and design principles of stamping parts.

The first is the requirements for the bending parts of precision metal stamping 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 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 metal stamping deep drawing parts:

1. The shape of the drawn part should be simple and symmetrical, and the depth should not be too large, so as to minimize the number of times of drawing and make it 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.

The design of precision metal stamping parts must meet the basic needs of products in various fields, so certain design principles are required:

1. It satisfies the use and technical performance of the product, and can be easily assembled and repaired.

2. It is beneficial to improve the utilization rate of metal materials, reduce the variety and specifications of materials, and reduce the consumption of materials as much as possible. Use low-cost materials where permitted, and make the parts as waste-free and waste-less as possible.

3. The shape is simple and the structure is reasonable, which is conducive to simplifying the mold structure and simplifying the number of processes, that is, the smallest and simplest stamping process is used to complete the processing of the entire part, reducing the use of other methods to process, and is conducive to the stamping operation. Facilitate the organization of mechanized and automated production to improve labor productivity.

4. Under the condition of ensuring normal use, try to make the dimensional accuracy grade and surface roughness grade as low as possible, and it is conducive to product interchange, reducing waste and ensuring stable product quality.

5. The design of precision metal stamping parts should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them, and is conducive to the extension of the service life of the die.

The above production quality requirements and design principles of precision metal stamping parts are summarized here, and I hope it will be helpful to everyone.
