How to maintain the discharge plate of the metal stamping die?

How to maintain the unloading plate in the metal stamping mold? Let's briefly talk about it below; 1. The disassembly of the unloading plate in the metal stamping mold can be balanced with two screwdrivers first, and then use both hands to balance the force to take it out. When it is difficult to disassemble, check whether the mold is cleaned. Whether the locking screws are completely disassembled, whether there is any damage to the mold caused by the jam, etc., the cause should be found out as soon as possible; 2. When assembling the unloading plate in the metal stamping mold, the punch and the unloading plate should be cleaned first. Add lubricating oil to the entrance of the column and the punch, put them in steadily, press them in place with both hands, and repeat several times; if it is too tight, find out the reason; 3. Check the unloading back plate if there is a pressing block on the fixed plate Whether the material is stolen enough, the material contact surface between the discharge plate and the concave mold will produce indentation after long time stamping (the gap between the discharge plate and the concave mold is generally the material thickness minus 0.03-0.05mm. When the indentation is serious, It will affect the pressing accuracy of the material and cause the product size to be abnormal and unstable. It is necessary to repair or re-grind the unloading insert and the unloading plate. 4. The middle-high sleeve of the metal stamping mold should be checked for accuracy, which varies. When it is high, it will cause the unloading plate to tilt, and its precise guiding and smooth elastic pressing function will be damaged, and it must be maintained.
