The reason for the faster wear of the punch in the metal stamping die

What is the main reason for the rapid wear of the punch in the metal stamping mold? Stamping parts processing manufacturers take you to take a look; ①The gap of the metal stamping parts die is too small. Generally, it is recommended that the total gap of the metal stamping part die is 20% or 25% of the material plate thickness. ②The centering of the convex and concave molds is not good, including the lack of precision of the mold base and the metal stamping mold guide components and the turret inserts. ③The temperature of the punch is too high, mainly due to the overheating of the punch caused by the same metal stamping die for a long time. ④Improper method of mold sharpening, resulting in the annealing of metal stamping parts, and increased wear. ⑤Partial unilateral punching, such as nibbling, angle of attack or shearing, the lateral force of aluminum alloy door and window fittings will make the punch to one side, and the gap on this side will be reduced, causing serious mold wear. If the machine tool stamping parts are processed The installation accuracy of the mold is not high, and the punch will deviate from the upper mold seriously, causing damage to the punch and the concave mold.
