The working principle of the punch-specific rapid die change system: the pneumatic oil pump unit is used to generate high oil pressure, the hydraulic oil enters the oil circuit connected with the clamp, and the piston and the lever mechanism of the clamp are driven to realize the mold. Quick clamping, quick release of the mold by means of system pressure relief and rapid release of the clamp, thus greatly reducing the time of the upper and lower molds.

Under the premise of system safety, the direct value of the punch-specific rapid die change system is the exchange time saved by the quick change system, that is, the added value created by the saved time.

Punch change time = mold clamp release time + mold removal time + mold preparation time (can be completed when the press is working) + mold shift time + mold positioning time + mold clamping time + press adjustment time (can be The first few orders are completed at the same time).

Indirect value of the punch-specific quick change system:
1. Shorten delivery time;
2. Reduce the inventory quantity;
3. Reduce resource fluctuations;
4. Reduce storage space;
5. Reduce (light) labor;
6. Reduce management load;
7. More small batch and leveling production capacity;
8. Enterprises are more competitive.
