What are the reasons for the jamming of the mold in the fabrication of precision automobile stamping parts?

Tooling is an indispensable and important equipment for the fabrication of precision stamping parts. In the process of fabrication, if you encounter poor stamping of the die, you need to analyze the principle in time, and propose an effective solution to deal with the problem well, in order to avoid greater failures. Reduce production costs and ensure smooth production. In the process of precision stamping parts, mold jam is a common problem, so how to solve it?

The reasons for the jamming of the mold in the fabrication of precision automobile stamping parts are as follows:

• 1. The feeding distance, pressing and loosening of the feeder are improperly adjusted. Workaround: Recheck the adjustment.
• 2. The delivery distance varies during production. Workaround: Readjust.
• 3. The stamping of the die is abnormal, and the sickle bend is caused. Solution: Eliminate the camber of the material belt.
• 4. The hole diameter of the guide material is insufficient, and the upper die pulls the material. Solution: study and punch positive hole convex and concave dies.
• 5. The material removal function of the material guide plate is not set properly, and the material belt is put on the belt. Solution: Modify the guide material, and put the anti-material belt on the belt.
• 6. The upper and lower parts of the bending or tearing position are not smooth. Solution: Adjust the force of the stripping spring, etc.
• 7. The material is curved, the width is out of tolerance, and the burrs are large. Solution: replace the material and control the quality of the feed.
• 8. The material is thin and warps during feeding. Solution: add upper and lower pressing materials between the feeder and the mold, and add upper and lower extrusion safety switches.
• 9. The mold is not set up properly, and the deviation from the verticality of the feeder is large. Solution: Re-erect the mold.
