Taizhou metal stamping parts, why will stamping parts be concave and convex +15 years stamping manufacturers tell you

The hardware responsible for the hardware stamping parts in Taizhou said that most of the causes of the unevenness of the hardware stamping parts are caused by the dust or iron filings attached to the raw materials or the appearance of the mold. It degrades the appearance of the product and also greatly reduces the productivity. So how do we avoid this problem? The following Xiaoshuo summarizes the following methods to reduce the bumps of metal stamping parts based on practice: 　　1. Inspection and correction of drawing dies: The drawing dies need to be regularly inspected and checked. Maintenance to reduce the occurrence of bumps and maintain a stable state. The usual method is to use samples to check the bonding scratches and processing surfaces of the blank holder (die fillet, punch fillet).　　2. 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. Therefore, it is necessary to observe the iron powder before stamping to avoid the occurrence of unevenness.　　3. Proper manipulator speed: For semi-automatic drawing die production, when the drawing punch is at the lower die position and the manipulator speed is fast, the burrs will fall on the upper part of the punch, causing bumps. In order to avoid this kind of problem, we can do the discharging test of the part before production, and set the speed and discharging angle of the manipulator reasonably so that it will not touch the part and the lower mold. 4. Check the cut surface: When cutting the coil material, the wear and breakage of the cutting die will produce a lot of tiny iron powder attached to the cutting edge, so it is necessary to check the double cut surface in the material area or the press line before stamping production, and clean it in time The sheet is deburred. Hardware, 15 years of focusing on Taizhou metal stamping parts, 5000 square meters production workshop, hundreds of precision processing production equipment, more than 20 Ru0026D and design engineers, monthly processing capacity of 100+ sets of molds and production capacity of 3 million punching times per day, stamping accuracy can reach 0.01mm, 16 quality inspection layers are strictly controlled. It can quickly solve the urgent problem of time when choosing hardware stamping processing, solve the problem of stamping accuracy, and solve the problem of production quality. Over the past 15 years, I have been conscientious and dedicated to the results of your needs only for the results of your work!
