How to care for stamping dies

The quality of stamping die is the prerequisite for producing good stamping parts. In the process of stamping parts production in a stamping factory, stamping dies are constantly worn. When the dies are worn to a certain degree, it will directly affect the normal production of stamping parts. Therefore, mastering the maintenance of the mold has become a necessary thing for the stamping plant. Precision has been engaged in the production of stamping parts for more than ten years, and can provide one-stop services for mold development, stamping, injection molding, and automated assembly. After years of production experience summary, we believe that stamping dies should be maintained from the following aspects: 1. General problems of repairing stamping dies: routinely inspect the structure of stamping dies, and constantly track the problems that occur in the mold; check the mold’s machinery Structure, check whether the positioning pin, side pin, ejector and ejection device and spring can work normally. Check the connection between the mold and the punch to ensure that the connection is normal; record the molding of the mold, the pressing material, the height dimensions of various balance weights and gaskets, and record them, compare them with the dimensions of the drawings, and repair the changed dimensions . 2. Overhaul of the drawing part mold: check the thinning rate of the deformation area of u200bu200bthe drawing part, check the area and degree of the roughened area of u200bu200bthe workpiece, and compare with the previous state to check whether there is an obvious deterioration trend; check the upper and lower molds of the mold , The coloring diagram between the blanking ring and the blanking plate can optimize and restore the areas that affect the quality of the parts; check the flatness of the drawbeads, grooves, forming areas and insert joints, and trim the materials that affect the forming. 3. Overhaul of the trimming and punching die: check and analyze the cross-section of the workpiece and waste, check and trim the trimming and punching gap; check and repair the cutting edge and corners of the punch and die; the cutter and the punch are combined In-depth inspection and maintenance. Check and optimize the scrap cutter; check whether there is abnormal waste in the mold, check the integrity of the scrap slide, and make the waste be discharged out of the mold in a reasonable and smooth manner. 4. Return spring detection: check whether the mold spring and other components are operating normally to ensure that the mold is correctly reset. 5. Inspection of mold parts: check the list of mold standard parts to ensure that there are enough spare parts in the warehouse; check the vulnerable non-standard parts in the mold to ensure that they can work normally.
