Aluminum Alloy stamping metal iron because material is relatively soft, expensive, easy to break and some Aluminum Alloy products also need subsequent processing, such as drawing, anode processing, especially in stamping production to produce top injuries, scratches, in the mold manufacturing should pay special attention to the following:1, for the project does not affect the number of cases, punching as far as possible behind the project, punching, and even for punching a large number of products, may consider more than one project, but also the punching line in the back.2, aluminum material is soft, and the mold is easy to block material, so in the design of mold gap should be put bilateral material thickness of 10% gap, the knife edge straight depth to 2MM is more appropriate, the taper to 0.8-1 degrees is appropriate.3, bending forming, because aluminum material in bending when easy to produce aluminum chip, will cause spot injury, indentation, aluminum raw material needs to stick PE film, in the roller and electroplating case, forming block with polishing hard chromium is better.4, the need for anode processing after stamping, such as pressing and flattening process of 180 degrees, the product can not be completely pressed, completely pressed will spit acid phenomenon for 0.2-0.3MM seam, acid to timely outflow, so we must do this step on the limiting block and calibration mode is higher than the norm out on.5, because the aluminum material is crisp, easy to crack, especially in the case of anti flanging, so try not to do the line, even if you want to do, but also to make the line width a little bit, a little lighter.6, all aluminum blade are required to use wire cut, to prevent the burrs and blanking is not smooth, easy to produce high temperature aluminum, so the punch hardness requirements of more than 60 degrees, at least with SKD11 material, has no D2 arithmetic matter punch.
Aluminum material is soft, so it is easy to produce the top injury, pressure injury, scratch and deformation in the stamping production. Besides the requirements on the die, the following points should be done in the stamping process:1, to make aluminum stamping, reducing non-performing rate, the first to do 5S, especially clean, including mold, punch table, pipeline and packaging materials must be no sharp debris, no dirt regularly clear rectification, the upper and lower mold must be clean without debris.2, found that product burr larger, must promptly send mold maintenance, and follow the results.3, aluminum parts easier to heat, and the backlog of hard together, so in the blanking, when the material needs to be coated with a little pressure on the oil (to heat dissipation, but also smooth to clear the material), and then stamping.4, punching more products need to do blow cleaning the mold surface, do product mould, keep clean, reduce top injury, injury must be found on top of the mold top point to find out and solve the injury problems to continue production.5, push the flat mold block will produce aluminum chip, so push block production every day, must be washed under the push block aluminum scrap.Our company with advanced production equipment and technology, relying on a strong technical team, and has established a perfect quality management system, ensure the reliable quality of products, products with first-class quality, reasonable price, sold in the city and region, sales performance is good, whether we are in a peer or in the guest account, have a high reputation.
