  • New energy hardware torsion spring
Product Introduction
New energy hardware manufacturing: Hardness testing of metal stamping parts adopts 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. Stamping processing includes punching, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) sheet metal materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin plates, stainless steel plates, copper and copper alloys Plate, aluminum and aluminum alloy plate, etc. The PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. After heat treatment, the hardness can reach about HRC-degree of chromium's hardness. Alloy stamping parts are #commonly used parts in the field of metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal strips. New energy hardware has a wide range of applications. The main purpose of the hardness test of stamping 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 Barcol hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate should use the Barcol hardness tester. In the stamping industry, stamping is sometimes also called sheet forming, but there is a slight difference. The so-called sheet forming refers to the forming method of plastic working with sheet material, thin-walled tube, thin profile, etc. as raw materials, which is collectively called sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered. Any pitting or indentation will be easily found. 4. Oiling inspection Wipe the surface of the outer cover with clean gauze. Then use a clean brush to apply oil evenly to the entire outer surface of the stamping in the same direction. Put the oiled stamping parts under strong light for inspection. When installing the mold on the small punch (T), first loosen the locking device of the guide rail, install the upper and lower molds, and then adjust the guide rail stroke until it meets the requirements and is locked tightly. In addition, when the high-punch mold is mounted, the single stroke must be hit. After the upper mold is locked, the lower mold is locked after hydraulic clamping, and another inspection is performed before the production of new energy hardware.
