DESCRIBE
参数
Rockwell hardness tester is used for hardness testing of metal stamping parts. Small stamping parts with complex shapes can be used to test. The plane is very small and cannot be tested on ordinary bench Rockwell hardness tester
the processing of metal stamping parts includes blanking, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tinplate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc
the main purpose of hardness testing of stamping materials is to determine whether the annealing degree of purchased metal plates is suitable for the subsequent stamping processing. Different kinds of stamping processing processes require plates with different hardness levels. The aluminum alloy plate used for stamping can be tested with Wechsler hardness tester. When the material thickness is greater than 13mm, it can be used with Babbitt hardness tester. The pure aluminum plate or low hardness aluminum alloy plate shall be used with Babbitt hardness tester
Introduction to burr removal methods on metal stamping parts
I: there are tools to remove burr of metal stamping parts
1 Hole: use a chamfering knife or the front end of a larger diameter drill
2 Edge: use file, oilstone, sandpaper, grindstone,
3 Welding slag: vibration slag removal tools can also remove brittle burrs
4 Outer diameter: the lathe is used for guiding angle during machining
5 There are also polishing, grinding and sand blasting. It depends on the workpiece and product requirements
2: the deburring process of metal stamping parts should be determined according to the product. If it is a single product, it should be removed manually
1 Electrochemical deburring. If self-made equipment, the cost is not high, and it is economical, effective and easy to use
2. Vibration grinding deburring (gear deburring) has high efficiency and good quality
3. Heat treated parts can also be deburred by shot peening, and the surface stress
4 The deburring effect of air gun with various shapes of gun head is better and the efficiency is also high
5 The following methods can be used for gear deburring: 1. Electrolytic deburring has good efficiency and good quality, but the equipment cost is too high for general small enterprises; 2. Vibration deburring is of average quality, but the cost is low. 3. Manual deburring is of good quality, but the efficiency may be lower; 4 rolling can be used. Stainless steel electrode
6 Pneumatic deburring
