Chinese machine - feeder - soft aluminum material stamping should pay attention to what?

Aluminum material is soft, expensive, easy to break, and some aluminum alloy products need follow-up processing, such as wire drawing, anode treatment, etc., in the production of stamping, easy to produce the top injury, pressure injury, scratch, deformation.
In the mold manufacturing should pay special attention to the following points:
1. without affecting the number of projects, as far as possible behind the hole. For a large number of punching products, may consider even if a project to do more, but also to punch holes 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, 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. for the anode after processing the stamping parts, such as pressing and leveling 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 that of the mold on.
5., because the aluminum material is crisp, easy to crack, especially in the case of anti folding, 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.
All 6. pieces of aluminum blade are required for wire cutting, to prevent 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.
In stamping production to do the following:
7. 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.
8. found that the product is big burr, must be sent to the mold maintenance in time, and follow the results.
9. aluminum parts easier to heat, and the backlog of hard together, so in the blanking, the material needs to be painted on the point of pressing oil (to heat dissipation, but also smooth to clear the material), and then stamping.
10. punching more products need to be hit 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.
11. push the flat mold block will produce aluminum chip, so push block production every day must be washed under the push block aluminum scrap.
1) punch easily in punching aluminum scraps into the off board, and will produce high temperature punch wear or softening, so the production 3-7 days must be cleaned regularly punch or punched edge polishing, unfortunately the need for timely replacement.
2) for a 180 DEG bending flat products, must not 10-30 will tear film viewing PE folding without rupture, due to aluminum material in the material will have components of inequality, especially for the replacement of manufacturers stamping materials required strictly check first
