Due to thermal expansion and contraction of
aluminum profiles, after being discharged, its specifications will be about 1 silk meter u003d 10 millimeters smaller than the mold specifications. The most widely used non-ferrous metal structural material in the aluminum alloy profile industry is in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, and decoration. For square pipes and round pipes, when the new mold comes, first measure whether the wall thickness is uniform, and then check whether the working belt is flat, before starting to use or repair. The most widely used non-ferrous metal structural material in the aluminum alloy profile industry is in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, and decoration. 1. It's fast (bulge up): block the fast place or the slow place, grind the guide port in the feed direction on the fast side of the working belt (slow down), and grind the guide port in the discharge direction on the slow side of the working belt. Narrow the working belt (speed up); 2. It is slow (recessed, there is also a slow drum): the place that is worn slowly or that is blocked, the opposite direction is the same as the above (solid and hollow appear on the same aluminum profile, and the solid is larger than the hollow. The material started to be slow at first, and then it followed up); 3. The material head was not fast, and later it became fast: the work is uneven, grind it in the direction that makes it slow, and make it work smoothly; 4. The material head is not slow, and later Slow is false and slow: the working belt is not flat, grind it in the direction that makes it fast, and make it work flat; 5. Twisting with teeth: grind in the opposite direction of the twisting direction (because you grind in which direction it will go Which direction is twisted); 6. The groove with groove is small and large: Grind a storage hole on the side of the working belt adjacent to the groove, and block the surrounding area; 7. The profile has scratches: the new mold nitriding test mold After polishing the front pilot port, the rod is not good, and the work contains garbage; 8. The aluminum alloy profile has ribs: the mold working belt is cracked, washed off, and there are small scratches. Solution Return to the factory for repair, use a grinding pin to scratch around the working belt Grind left and right flatly to make it slightly concave; 9. Uneven wall thickness: knock the side with the thinner wall of the upper mold, and grind the side with the thicker wall; 10. The radiator and similar radiator teeth are slower or faster: slower Open a storage hole on the top of the tooth, if it is fast, it will be blocked; 11. With screw holes and small holes of the same kind are slow and fast: open the deflector hole, polish the small hole working belt, and block the diversion hole . The most widely used non-ferrous metal structural material in the aluminum alloy profile industry is in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, and decoration.
