Aluminum intermediate alloy stamping dies are very easy to break and part of the aluminum intermediate alloy products need to be processed afterwards, such as metal brushing, oxidation treatment, etc. It is especially easy to cause top wound and scratch during the manufacturing of stamping dies.
The following aspects should be noted at the die manufacturing level.
For the aluminum intermediate alloy project number does not affect the condition of punching as far as possible in the back of the project punching, and even for the total number of punching more products can be considered to do one more project but also punching holes in the back of the line.
Aluminum intermediate alloy is too soft and the mold is very easy to material blockage, so in the design of the program mold put gap must be put multilateral material thickness 10% gap, wound straight deep bit to 2MM more suitable, the degree of finish to 0.8-1 ° for suitable.
Aluminum intermediate alloy bending forming, because the aluminum material in the bending is very easy to cause iron chips, will lead to point injury ﹑ embossing, aluminum raw materials need to paste PE film, in the case of roller and electroplating process, forming block to polishing polishing plating hard chrome is appropriate.
Aluminum intermediate alloy for the production of metal stamping parts that need to be anodized after processing, if the lay flat ﹑ push flat process 180 °, the product can not be completely pressed together, completely pressed together will cause spitting acid condition, have to leave 0.2-0.3 MM seam, to facilitate the success of the acid immediately discharge, so here on the process must do limit switch block and calibrate the mold height over the mold.
