What are the daily maintenance work of stamping dies?

The quality of stamping dies is the most basic requirement for the qualification of stamping products, and in the process of stamping processing, stamping dies are a process of constant wear and tear. The wear of the mold directly affects the normal production of stamping parts, so mastering the maintenance of molds has become a necessary ability for a stamping factory. The maintenance of stamping dies is generally carried out in the following aspects: ① General problem maintenance of stamping dies: routine inspection of structural damage of stamping dies, continuous tracking of mold problems that have occurred; inspection of mechanical structure problems of molds , Check whether the positioning pins, side pins, ejector and ejection devices, springs, etc. can work normally. Check the connecting part of the mold and the punch to ensure that the connection function is normal; make a record of the mold's molding, pressing, various balance weights and the height of the gasket, etc., and compare the dimensions of the drawing to change the size Repair the parts of the mold; inspect the movable guide parts of the mold, such as the upper and lower molds, the pressing ring, and the pressing plate, to ensure that the guiding gap is reasonable and without serious wear; and the appearance inspection of the return spring or polyurethane to ensure its normal operation; Inspect the appearance of the mold, repair and improve unreasonable or missing identification texts and signs; check whether the positioning parts such as pins are working properly, check whether the fastening screws are working properly, and tighten with a reasonable torque. ②Maintenance of drawing parts mold: check the thinning rate of the main deformation area of u200bu200bthe stamping and drawing parts, check the roughness area and degree of the workpiece, and compare with the historical state for obvious deterioration trends; check the upper mold, lower mold, and pressure of the mold The coloring diagram between the material ring and the binder plate optimizes and restores the areas that affect the quality of the parts; check the smoothness and smoothness of the drawbeads, grooves, molding areas and the joints of the inserts, and repair the materials that affect the molding Casting and welding sand holes; check, repair and track the existing solder joints in the mold functional area; check the surface treatment area for serious wear or bump damage. ③ Overhaul of trimming and punching dies: inspect and analyze the cross-section of the workpiece and waste materials, inspect and repair the trimming and punching gap; inspect and repair the inserts, punches, and the cutting edges and corners of the dies; Check and repair the depth of the knife and punch. Check and optimize the length of the scrap cutter; check whether there is any abnormal waste in the mold, and check the integrity of the scrap chute, so that the waste can be discharged out of the mold reasonably and smoothly. ④ Inspection of the return spring: check whether the mold spring and other mechanisms are working properly to ensure that the mold returns safely and correctly; whether the lubrication is normal. ⑤ Inspection of stamping die parts: check the list of standard parts of the mold to ensure that there are enough parts in the warehouse; check the vulnerable non-standard parts of the mold to see if it can work normally. As long as the daily inspection work of the stamping die is mastered, the damage rate of the die can be minimized, and the problem of the die can be solved as soon as possible, and the normal stamping production will not be affected.
