Suzhou precision stamping processing plant, the cause of the bumps in metal stamping parts + 3 million punching next day

The hardware in charge of the Suzhou precision stamping processing plant said that most of the causes of the unevenness of the metal 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 five methods to reduce the bumps of metal stamping parts according to practice: 　　1, inspection and correction of drawing dies: 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, the iron powder must be observed before punching 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 the double cut surface must be checked in the material area or the press line before stamping production, and cleaned in time The sheet is deburred.　　5. Inspection of sheet material cleaning device: It is necessary to inspect and trim the cleaning device at the same time before stamping production, so that it may clean the sheet material more effectively. This is also very necessary, and also needs to pay attention to the roller gap and the quality of the cleaning oil. The detailed method is to apply red paint on a steel plate to make it clean and settle. Currently, check the antecedent shape of the red paint being cancelled. If the removal rate is not up to the standard, it is necessary to check, trim, clean and settle. When the cleaning oil is lacking, it must be cut in time.　　 Mastering the five major methods to reduce the bumps of metal stamping parts can avoid the bumps and bumps of the stamping parts and produce defective products as much as possible. Hardware, 15 years of focus on Suzhou precision stamping processing plant, 5000 square meters production workshop, hundreds of precision processing production equipment, more than 20 Ru0026D and design engineers, monthly 100+ sets of mold processing capacity and daily production capacity of 3 million punches, stamping accuracy can be Up to 0.01mm, 16 quality inspection layers are strictly checked. 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!
