Dimensional accuracy of metal stamping parts
Metal stamping products are widely used in all areas of our lives, including some electronics, auto parts, decorative materials and other parts. Hardness testing metal stamping metal stamping parts using Rockwell hardness tester. Small, with complex shape stamping components, can be used for small test surface, can not be tested on the normal desktop Rockwell hardness. The following editor will introduce what is the size of precision metal stamping parts.
The dimensional accuracy of metal stamping parts refers to the difference between the actual working size of the stamping part and the basic structure size. The smaller the difference, the higher the calculation accuracy of the metal stamping part. The main influencing factors that cause the dimensional data error of the company's hardware stamping parts are: the manufacturing technical accuracy of the convex and concave molds; the gap between the convex and concave molds; the elastic recovery of the material after stamping; the accidental environmental factors in the production development process, such as inaccurate positioning, Material product performance is unstable and so on. The surface quality of metal stamping parts should not be higher than the surface quality of the raw materials, otherwise it needs to increase the follow-up processing to achieve, increase the production cost.
The dimensional accuracy of metal stamping parts can generally be divided into two categories: precision and ordinary. The accuracy level is the accuracy that can be achieved by the stamping process, while the general level is the accuracy that can be achieved by a more economical method. In the case of high mold manufacturing accuracy, the dimensional accuracy of metal stamping parts can reach 0, and the inner hole size can reach 9.
