Metal stamping parts are widely used in various fields of our lives.
Hardware: parts processed from steel or some non-ferrous metals, processing methods: cold/hot stamping, extrusion, rolling, welding, cutting, etc., including other processes, the definition is relatively broad.
Stamping parts: The most used in metal processing, refers to the steel/non-ferrous metal and other plate molds at room temperature, which are formed into the specified shape by the pressure required for processing by the press.
Including some electronic devices, auto parts, decoration materials and so on. The stamping parts we usually refer to are cold stamping parts. For example, if you want to turn a piece of iron into a fast food plate, you must first design a set of molds. The working surface of the mold is the shape of the plate. Press the iron plate with a mold, and it will become the plate you want. This is cold stamping, which is to stamp the hardware material directly with the mold.
The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stampings with complex shapes can be used to test the surface is too small to be detected on ordinary benchtop Rockwell hardness testers.
Stamping processing includes blanking, bending, deep drawing, forming, finishing and other processes. The materials for stamping parts processing are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin-plated plates, stainless steel plates, copper and copper alloys plate, aluminum and aluminum alloy plate, etc.
The PHP series portable superficial Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in the fields of metal processing and machinery manufacturing. Stamping processing is a processing method that uses a mold to separate or form metal strips. Its application range is very wide.
The main purpose of hardness testing of stamping parts is to determine whether the annealing degree of purchased metal sheets is suitable for subsequent stamping parts processing. Different types of stamping parts processing technology require plates of different hardness levels. The aluminum alloy plate used for stamping processing can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, a Barcol hardness tester can be used instead. A pure aluminum plate or a low-hardness aluminum alloy plate should use a Barcol hardness tester.
In the stamping parts industry, stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet forming refers to the use of sheets, thin-walled pipes, thin profiles, etc. as raw materials for plastic processing. The forming methods are collectively referred to as sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered.
