Problems and methods that should be paid attention to in the stamping of industrial aluminum profiles

Because the material of aluminum alloy stamping is softer than metal iron, it is expensive, easy to break, and some aluminum alloy products require subsequent processing, such as wire drawing, anodizing, etc., which are particularly prone to top scratches and scratches during stamping production. In terms of manufacturing, pay special attention to the following points: 　　 1. For punching holes that do not affect the number of projects, try to arrange the punching holes in the back of the project punching, even for products with a large number of punching holes, consider doing one more project and also arranging the punching holes. Punch at the back. 　　 2. The aluminum material is soft and the mold is more likely to block the material, so when designing the mold gap, a gap of 10% of the thickness of the bilateral material should be placed. The straight depth of the knife edge is more suitable for 2MM, and the taper is 0.8-1°. .　　3. When bending and forming, because the aluminum material is easy to produce aluminum chips during bending, it will cause spot damage and indentation. The aluminum raw material needs to be coated with PE film. In the case of rollers and electroplating, the forming block is polished and hardened. Chromium is better. 　　4. For stamping parts that need post-anodization, if there is a flattening and flattening process of 180°, the product cannot be fully pressed. Complete pressing will cause acid spitting, and a 0.2-0.3MM seam is required. In order for the acid to flow out smoothly and in time, it is necessary to make a limit block and calibrate the mold higher than the mold in this process. 　　 5. Because the aluminum material is brittle and easy to crack, especially in the case of reverse folding, try not to do it. For crimping, even if it is to be done, make the crimping a little wider and lighter. 　　6. All aluminum knife edges are required to be cut with a slow-moving thread to prevent burrs and irregular blanking. Aluminum parts are prone to high temperatures. Therefore, the hardness of the punch is required to be above 60°, at least the material of SKD11 is above, and there should be no inferior punches such as D2. 　　 Aluminum is soft, so it is easy to cause top damage, crushing, scratching, and deformation during stamping production. When the mold is required to be required, the following points must be achieved in the stamping production: 　　 1. In order to stamp the aluminum parts well and reduce the defect rate, the first step is to do a 5S, especially cleaning, including the mold and the punching table. , The assembly line and packaging materials must be free of sharp debris, no dirt, and regular clear rectification, and the mold must be cleaned up and down, and there is no debris. 　　 2. If the product is found to have large burrs, it must be sent to the mold for repair in time and follow up to the result. 　　3 Aluminum parts are more likely to heat up and become hard when they are stacked together. Therefore, when punching and blanking, it is necessary to apply a little pressure plate oil on the material (which can dissipate heat and smoothly dredge the blanking) and then press. 　　4. Many products need to be hit to clean the surface of the mold, and the tube condenser is to ensure that the mold and the product are always clean and free of debris, and the top damage is reduced. If the top damage is found, the problem of the top damage of the mold must be found and solved before the production can continue. .　　5. Pushing the mold and pushing block will produce aluminum scraps, so the aluminum scraps under the pushing block must be cleaned after the production of the pushing block every day.
