How To Maintain The Discharge Plate in The Stamping Die?

For the disassembly of the discharge plate in the stamping die, first use two drivers to pry it up, 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 the mold damage caused by material jam should be found out, and then deal with it accordingly. Do not dispose blindly.

When assembling the unloading plate, first clean the punch and the unloading plate, add lubricating oil to the guide post and the punch guide, place them stably, and then press them in place with both hands, and repeat several times. If it is too tight, find out the cause (whether the guide pillar and guide sleeve are guided normally, whether each part is damaged, whether the new punch can pass through the discharge plate smoothly, and whether the position is correct), find out the cause and then deal with it accordingly.

If there is a pressing block on the fixed plate, check whether the stolen material on the unloading backplane is sufficient. The material contact surface between the discharge plate and the die, Indentation occurs during long-time stamping (the material thickness between the unloading plate and the female die is generally reduced by 0.03-0.05mm. When the indentation is serious, it will affect the pressing accuracy of the material, resulting in abnormal and unstable product size. It is necessary to repair or regrind the unloading insert and the unloading plate. The contour sleeve should be checked for accuracy. When it is unequal in height, it will cause the unloading plate to tilt, and its precise guidance and stable elastic pressing function will be damaged, which must be maintained
