Aluminum alloy scratch, bruises and solutions
[China Aluminum Industry Net] Aluminum alloy scratches, scratches, and bumps are surface damages that occur when aluminum extrusions flow out of the die hole and come into contact with objects, equipment, etc. in subsequent processes. There are mainly the following reasons: Wheel Hub Assembly For JAGUAR,Front Wheel Bearing Assembly,Rear Wheel Bearing Hub Assembly,Hub And Bearing Assembly SHAOXING ZHENGHONG AUTO PARTS CO.LTD , https://www.kontinental-bearing.com
1, artificial drag on the swing bed constitutes a bruise;
2. In the course of transportation, the profiles resist each other or knead to form damage; the copper belt 3, the mold cavity or the mission belt have debris, the mold mission has a low hardness, and the mission belt surface is injured when kneading. Scratched profile
4. There are hard inclusions in the exposed metal or graphite strip on the discharge track or oscillating bed. When it comes into contact with the profile, it will scratch the surface of the profile.
5. When the fork material rod sends the profile from the discharge rail to the swing bed, the profile is damaged due to the excessive speed. Chromium zirconium copper plate common solution:
1. Strengthen the control of the quality of the ingot;
2. Reasonably arrange the profiles in the material frame to avoid conflicting with each other;
3, improve the quality of mold repair, die punctuality nitride and strict implementation of the nitriding process; aluminum bronze plate 4, the production should be gently, try to avoid arbitrary drag or flip profile;
5. Insulate the profiles and auxiliary tools with soft felt to minimize contact damage between profiles and auxiliary tools
