The metal spring piece is a kind of sheet metal formed and processed by mould, which needs to be used in high-speed punch. If the operation is improper, the mold will be seriously damaged, and the safety of the operator will also be injured, so Heju precision will tell you the safe operation steps in the processing of metal shrapnel.
1. Before pulling the mold, it is necessary to make sure that the support plate of the feeding port of the mold has been loosened and removed. 2. The hinge hole position on the door panel can be easily installed, and the hole can be punched into a circle shape to facilitate fine adjustment up and down. 3. When the mold cannot be pulled, one person can pull outward and one person can push backward. (do not push the die backward at the same time to push the die out of the punch platform). You can also use the die lifting screw to wind the screw hole of the lower die base, and then lift both hands up a little at the same time and then pull it out. 4. The gap between the hinge and the portal frame must be considered when installing the hinge hole on the portal frame. The welding position of the three hinges is very important, and the concentricity requirement is very high. I think it is necessary to punch more holes for positioning hinge when punching the hinge. When processing the hinge, two protrusions can be punched on the hinge, corresponding to the hole on the door plate, which is used for positioning. 5 The tool car should not turn too fast to prevent the guide plate or material support plate from hanging on the punch or the sound insulation cover of the punch, causing damage to the die parts or sliding of the die. 6. When the mold is shut down normally, it is necessary to move the mold inching until the guide needle enters the round hole of the material belt. ）It is forbidden to stop the mold at the bottom dead center. (easy to reduce the service life of in mold spring)
The above is about the six safety operation steps of metal spring stamping. Hope that in the daily shrapnel processing process, each peer can strictly follow the safety production process to prevent the occurrence of abnormal quality of hardware shrapnel.
