1. During the bending and forming of sheet metal, special attention shall be paid to the manufacturing of industrial aluminum profile stamping die and abrasive tools. Because the aluminum material is very easy to cause iron filings during the bending of sheet metal, which will lead to point injury and embossing, the aluminum raw materials need to be pasted with PE film. Under the condition of roller and electroplating process, the formed blocks should be polished and plated with hard chromium.
2. All die-casting wounds are required to be cut with slow thread to prevent rough edges and unsatisfactory blanking. Industrial aluminum profile processing is very easy to cause high temperature, so the punch strength is required to be above 60 °, SKD11 material can be used, and there can be no D2 differential punch.
3. In view of the situation that the number of engineering projects is not endangered, the punching shall be arranged behind the engineering projects as far as possible, and even for the commodities with a large number of punching, it can be considered to make one more engineering project and punch the punching behind.
4. Because the aluminum material is brittle, it is very easy to crack, especially in the case of flanging, so it is not necessary to do the crimping as much as possible. Even if it is necessary, the crimping should be wider and shallower.
5. The aluminum material is too soft and the mold shell is very easy to be blocked by materials. Therefore, when the mold shell is placed in the design scheme, a gap of 10% of the thickness of multi edge material must be placed. 2mm is more suitable for the straight depth of the wound, and 0.8-1 ° is suitable for the finish.
6. For the metal stamping parts to be processed after anodizing, if there is a paving and leveling process flow of 180 °, the goods cannot be pressed, and the pressing of industrial aluminum profile will cause acid spitting. A 0.2-0.3mm seam must be reserved to facilitate the smooth and immediate discharge of acid. Therefore, the limit switch block must be made in the process flow and the die height shall be calibrated on the die shell.
The company is committed to the development, manufacturing and sales of industrial aluminum products and various civil aluminum products. It has supporting production equipment and suppliers such as aluminum rod melting and casting, large extruder, anodic oxidation line, coloring oxidation line, electrophoretic painting line, electrostatic spraying line and product machining.
