How to maintain the stripper of the continuous mold

Stamping parts manufacturers know that in the production of stamping molds, it is necessary to maintain the machinery and equipment in order to increase the life of the mold and increase the efficiency of production. Concave and convex molds, stripper plates, guide plates and mold gaps all require special attention. The author of this article will introduce how to maintain the stripper of the continuous stamping die. 1. To remove the stripper, first use two screwdrivers to balance the prying, and then use both hands to balance the force to take it out. When it is difficult to disassemble, check whether the inside of the mold is cleaned, whether the locking screws are completely disassembled, whether the mold is damaged due to jamming, find out the reason and then do the corresponding treatment, and do not blindly dispose of it. 2. When assembling the stripper plate, first clean the punch and stripper plate, add lubricating oil to the guide post and the lead-in place of the punch, put it in steadily, press it in place with both hands, and repeat it several times. If it is too tight, find out the reasons (whether the guide post and guide sleeve are oriented normally, whether there are damages in various parts, whether the new punch can pass the stripper plate smoothly, whether the position is correct), and then deal with it accordingly. 3. If there is a press block on the fixed plate, check whether the clearance on the stripping back plate is sufficient. The material contact surface between the stripper plate and the die is stamped for a long time to produce indentation. When the indentation is serious, it will affect the pressing accuracy of the material and cause the product size to be abnormally unstable. It is necessary to correct the stripper insert and the stripper. Repair or re-grind. 4. The contour sleeve should be checked for accuracy. When it is not equal in height, the stripper plate will be tilted, and its precise guiding and smooth spring pressing function will be damaged and need to be maintained.
