Hardware: Parts processed from steel or some non-ferrous metals, metal stamping parts processing methods: cold/hot stamping, extrusion, rolling, welding, cutting, etc. also include some other processes, the definition is relatively wide.
Stampings: Most used in metal machining refers to the use of steel/non-ferrous metals and other sheet metal molds at room temperature. The pressure required for processing is provided by the press to form the specified shape.
Portable surface Rockwell hardness testers are well suited for testing the hardness of these stamped parts. Alloy stampings are the most commonly used parts in metal processing and mechanical manufacturing. Stamping parts processing is a method of separating or forming a metal strip using a mold. Its application is very broad.
1, hardness testing of stamping parts materials
The hardness test of the stamping materials, the main purpose of the metal stampings is to determine whether the degree of annealing of the purchased sheet metal is suitable for the subsequent stamping parts processing. Different types of stamping parts processing technology require different hardness level sheets. Metal stampings Aluminium alloy plates used for stamping parts can be tested with a Vickers hardness tester. When the material thickness is greater than 13 mm, a Barcol hardness tester can be used. A pure aluminum plate or a low hardness aluminum alloy plate should be a Barcol hardness tester.
2, hardness testing of stamping parts mold
The main material for the stamping die is die steel (including tool steel and high speed steel) and sometimes carbide.
Hardness testing of metal stampings uses Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes. Metal stampings cannot be tested on an ordinary bench Rockwell hardness tester
