Issuing time:2019/7/23 11:54:44

The processing metal stamping die can be cut in one step. At least the blank is cut or sawed on the raw material of the die steel, and then roughed. The rough, rough surface, size, etc. are relatively poor, so you need to grind the grinding machine once and then to grind it. This time is rough machining, so the size requirements are not high, generally enough to keep the tolerance of 50 wire. After roughing, heat treatment is required. The general heat treatment is a special heat treatment plant. There is not much to be introduced.
After the heat treatment, it is necessary to carry out finishing. Generally, the grinding machine is first used for fine grinding, and the dimensional requirements at this time are relatively strict. Generally, the accuracy should be around 0.01, and the specific precision requirements should also refer to the complexity and precision of the metal stamping parts that the metal stamping die needs to process.

After the grinding machine is finished, the design drawings before the installation are started for processing. Generally, the thread holes are first threaded, and then the upper thread cutting is performed according to the drawings to cut out the required size and shape, and then the milling machine, the CNC, etc., as the case may be. This specific also depends on the complexity of metal stamping parts.

To sum up, the equipment needed for metal stamping dies includes sawing machines, lathes, wire cutting, electric sparks, milling machines, drilling machines, grinding machines, etc. These are also a qualified metal stamping die fitter that requires skilled operation, but with In the development of the industry, in the process of processing metal stamping dies, many processes are also responsible for the external factory. After all, the industry has a specialization.
