Metal stamping

Regarding the maintenance of metal stamping dies:

1. Keep the surface of the convex and concave die clean. The blank of the precision stamping part needs to be wiped clean before deep drawing to avoid that the work surface of the die or the surface of the material is not clean and mixed with debris, which damages the surface of the precision stamping part and affects the quality.

2. Adjust the appropriate clearance of the convex and concave dies to avoid the surface of the workpiece being scratched when the drawing is too small or uneven.

3. Grind the corner radius of the die to avoid rough round corner surface of the die. The surface is scratched.

4. Appropriately increase the hardness of the surface of the male and female molds and check the surface of the male and female molds regularly when drawing. Even if the metal scraps are left behind, when the metal and metal wastes are attached to the surface, the drawing will be deepened Pull marks on precision stampings.

5. Use lubricants suitable for the deep-drawing process. If necessary, filter the lubricant before use to avoid impurities from entering. If the quality of the lubricant is poor, the surface roughness of the drawn precision stamping parts will increase, reducing the precision and quality of the stamping.

Common bad phenomena in stamping:

1. Jumping waste: refers to jumping out of the cavity of the concave mold during the stamping process, causing defects such as embossing.

Lösung:

  • Add ejector in the punch
  • Fügen Sie ein sekundäres Luftloch in den Stempel ein
  • Verjüngen Sie die Stirnfläche des Stempels
  • Verwenden Sie einen Matrizeneinsatz als Luftblasgerät

2. Grat: Scharfe Rippen am Querschnitt des Produkts nach dem Stanzen verbessern im Allgemeinen den Produktionsprozess und verbessern die Stanzbedingungen, wodurch der Grat verringert werden kann.

Lösung:

  • Schleifen Sie die Messerschneide
  • Kontrollieren Sie die Bearbeitungsgenauigkeit und ändern Sie das Konstruktionsspiel
  • Der neue Stempel und der konkave Einsatz

3. Faltenbildung und Rissbildung: Sie tritt häufig in scharfen Ecken von gedehnten Teilen und Formteilen auf.

 

Lösung:

  • Polieren
  • R-Winkel erhöhen
  • Zunehmende Rippen
