How to avoid unevenness in the production of metal stamping parts in Guangdong + 3 million punching next day production capacity

Many friends from the hardware stamping parts processing plant in Guangdong have reacted. In the production and processing of stamping parts, various factors often cause unevenness on the surface. Today, Xiaoshuo will sort out and share with you what are the reasons for this phenomenon: From the inspection and correction of the drawing die: the drawing die needs to be regularly inspected and maintained to reduce the occurrence of unevenness and maintain a stable state. The usual practice is to use samples to check the bonding scratches of the blank holder and the processing surface (the rounded corners of the die, the rounded corners of the punch). From the inspection and correction of the shearing die: the reason for the unevenness after the shearing process is that iron powder is produced during the shearing process, so the iron powder must be observed before punching to avoid the occurrence of unevenness. Check the cut surface: When cutting the coil, the wear and damage of the cutting die will produce a lot of tiny iron powder attached to the cutting edge, so the double cut surface must be checked in the material area or the press line before the stamping production, and the sheet should be cleaned in time Remove burrs. The bending caused by the internal stress of the steel plate. The internal stress generated by the steel plate during rolling and winding will move to the surface after stamping, and the stamped parts will be bent. The solution is to remove the internal stress before stamping (it can be done by leveling machine or annealing), or it can be leveled after stamping, or by heat treatment annealing and other methods. If it reaches the standard, it needs to be inspected, repaired, cleaned and settled. When the cleaning oil is lacking, it must be cut in time. Hardware, 15 years of focusing on the production of metal stamping parts in Guangdong, 5000 square meters production workshop, hundreds of precision processing production equipment, more than 20 R u0026 D design engineers. The monthly processing capacity of 100+ sets of molds, the daily production capacity of 3 million punching times, the stamping accuracy can reach 0.01mm, and the 16 quality inspections are strictly controlled. It can quickly solve the time-urgent problem of stamping parts, solve the problem of stamping accuracy, and solve the problem of production quality for you. Choose, choose rest assured!
