Cold forming skills of precision stamping shrapnel 'hardware'

Cold forming skills of precision stamping shrapnel: 1. Cold forming skills can be automated at one time. The cold forming machine has now expanded to 12 jaws. The steel wire in the size of (0.3～14)mm can basically be formed at one time by the 8-jaw forming machine. The current development direction of forming technology equipment: ①Increase the forming speed, the primary development trend is to increase the forming speed of the equipment, that is, the output power; ②The durability of the equipment is improved by improving the precision of equipment parts and strengthening the heat treatment effect; ③Adding length sensors and The laser rangefinder is used for the active closed-loop operation of the CNC forming machine to control the manufacturing process. 2. The scale of cold forming skills. Nowadays, the large wire diameter precision stamping spring spring coiling machine can reach 20mm, u003d2000MPa, and the winding ratio is 5. There are still limitations to the cold forming skills of shrapnel for reduced or equal diameter Minic-Block precision stamping parts and shrapnel for offset precision stamping parts.
