Method to reduce the bumps of metal stamping parts-hardware

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, which degrades the appearance of the product and also greatly reduces the productivity. So how do we avoid this problem? The following author summarizes the following methods to reduce the unevenness of metal stamping parts based on practice. 5 methods to reduce the unevenness of stamping parts: 1. Inspection and correction of drawing die: drawing die Regular inspection and maintenance are required 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, 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 bi must check the double cut surface in the material area or the stamping line before stamping production, and timely Clean the sheet to remove burrs. 5. Inspection of sheet metal cleaning device: Before stamping production, bi needs to be inspected and trimmed at the same time to clean and settle, so that it may clean the sheet more effectively. This is also very necessary, and it is also necessary 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 of stamping parts and produce defective products as much as possible. The above is the introduction of the hardware author. I hope that some of the common work stations mentioned in your search for metal stamping parts manufacturers will be helpful. Because what some manufacturers say are words used in the industry, they need to know more information about metal stamping parts, please consult:
