Folding detection
The hardness testing of metal stamping parts adopts Rockwell hardness tester. Small and complex shaped stamped parts can be used to test surfaces that are too small to be tested on ordinary desktop Rockwell hardness testers.
Stamping processing includes processes such as punching, bending, deep drawing, forming, and finishing. The materials used for stamping processing are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet and strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plated plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.
The PHP series portable surface Rockwell hardness tester is highly suitable for testing the hardness of these stamped parts. Alloy stamping parts are the most commonly used components in the fields of metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal plates and strips. Its application range is very broad.
The hardness testing of stamping materials is mainly aimed at determining whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping processing. Different types of stamping processing techniques require sheets of different hardness levels. Aluminum alloy plates used for stamping parts processing can be tested using a Vickers hardness tester. When the material thickness is greater than 13mm, a Babbitt hardness tester can be used instead. Pure aluminum plates or low hardness aluminum alloy plates should use a Babbitt hardness tester.
In the stamping industry, stamping, as introduced by Shenzhen Chuangxing Hardware Products Factory, is sometimes referred to as sheet metal forming, but with slight differences. The so-called sheet metal forming refers to the forming method of plastic processing using sheet metal, thin-walled tubes, thin materials, etc. as raw materials, collectively known as sheet metal forming. At this time, the deformation in the direction of thick plates is generally not given much consideration.

Folding design principles
(1) The designed stamping parts must meet the requirements of product usage and technical performance, and be easy to assemble and repair.
(2) The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and minimizing material consumption as much as possible. If possible, use low-cost materials to achieve zero waste and minimal waste cutting of parts.

(3) The designed stamping parts must have a simple shape and a reasonable structure, which is conducive to simplifying the mold structure and simplifying the number of processes, that is, completing the entire part processing with the least and simplest stamping process, reducing the need for other methods of processing, and facilitating stamping operations, facilitating the organization to achieve mechanization and automation production, and improving labor productivity.

(4) The designed stamping parts should have lower requirements for dimensional accuracy and surface roughness levels while ensuring normal use, which is beneficial for product interchangeability, reducing waste, and ensuring stable product quality.
(5) The designed stamping parts should be conducive to processing them using existing equipment, process equipment, and process flow as much as possible, and to extending the service life of the stamping die.
