We usually need to use metal processing parts, do you know how to detect it? What I want to talk about today is about the inspection items of hardware processing parts. What are the specific ones? The editor of 7Swords will give you specific details.

metal processing parts

Generally, when we carry out the hardness test of Dongguan hardware stamping parts, most of them use Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the surface is very small, which cannot be tested on an ordinary desktop Rockwell hardness tester.

Dongguan hardware stamping parts also include punching, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled sheet metal materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate Wait. The PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal strips. Its application range is very broad.

The main purpose of the hardness testing of metal processing parts is to determine whether the annealing degree of the purchased metal sheets is suitable for the subsequent stamping parts processing. Different types of stamping parts processing techniques require plates of different hardness levels. The aluminum alloy plate used for stamping parts can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, the Bar col hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate should use the Bar col hardness tester.

In the stamping industry, stamping is sometimes called sheet forming, but there is a slight difference. The so-called sheet forming refers to the forming method that uses sheets, thin-walled tubes, thin profiles, etc. as raw materials for plastic processing, collectively called sheet forming, at this time, the deformation in the direction of the thick plate is generally not considered.
