What is the matter of the upward movement of waste in stamping parts processing?

Stamping parts processing plant, processing metal stamping parts, metal stamping parts, mechanical parts, etc.; what is the upward movement of waste? The upward movement of the waste refers to the phenomenon that the waste in the die is brought up with the rise of the punch during the punching of the stamping part, and then falls into the die. If the phenomenon of the upward movement of the waste occurs, on the one hand, it will be caused by Careless operation leads to personal injury and death accidents; on the other hand, mold breakage can also be caused during automated production, so measures must be taken to solve it immediately; analysis of the reasons for the upward movement of waste in stamping parts processing; 1. When the gap is too large It is easy to move up the waste of stamping parts; 2. If the straight wall of the die is polished or ground, the waste will move up due to the too smooth position; 3. The straight wall of the die is too high, and the waste is easy to occur when the wall is blocked. The stamping waste material moves upward; 4. When it hits the back of the die and the waste material is blocked, it is easy to cause the waste material to move upward; 5. Compared with the thickness of the plate, the shape of the blanking waste material is large and thin, and it is tightly adsorbed under the punch; 6. Adhesion occurs due to the use of high-viscosity lubricating oil; 7. After the die is ground, the cutting edge is too sharp; 8. The position and function of the discharge plate are not suitable 9. The adsorption phenomenon is caused by magnetism; 10 , The punch is inserted into the die too little; debugging method; 1. Select the appropriate gap value to modify; 2. Use a rough grinding wheel when grinding the straight wall of the die; for punching with low dimensional accuracy, use a drilling machine to process In the straight wall part of the die edge, there is rarely the phenomenon of stamping waste moving up; 3. It is anticipated in advance that the straight wall of the reground die will have the risk of waste moving up. In addition, because the rear collision will cause burr clogging and waste upward movement, the straight wall of the die should be corrected; 4. Insert the punch 3~5mm into the die, and the clogged waste is limited to three pieces or less; 5. When the material is very thin, Due to oil, magnetism, vacuum and other reasons, waste is easily adsorbed on the bottom of the punch. 6. After grinding, the concave mold has a strong tendency to move up the waste. If there is any upward movement, the cutting edge needs to be slightly dulled with a grinding wheel; 7. During mass production, the cutting edge will produce magnetism, so it is necessary Demagnetize regularly; 8. When removing the waste from the punch, if you are not careful, accidents will occur once the stamping waste falls, so you need to take corresponding measures. A thin baffle can be set on the straight wall of the concave mold. When the punch passes the baffle, the baffle is inserted to prevent the waste from falling; article recommendation: analysis of various problems in the debugging of metal stamping parts (2) Previous : Analysis of various problems in the debugging of metal stamping parts (2)
