Several typical structures of continuous mode

Continuous die is a kind of punching die. It has the characteristics of many stations and high efficiency. In order to ensure the quality of stamping parts, accurate positioning is very important. Today, we will introduce several typical structures of it according to the characteristics of its positioning.

1. Use the guide pin to locate

For products positioned with guide pins, the distance between the punching punch and the blanking punch is called the feeding step. During the operation, the initial position is limited by using the stopper pin, and the two front punches are punched. A hole, the spring that started using the stopper pin will reset after completion. The strip will be fed one step, and roughly positioned by the fixed stopper pin. When blanking, it needs to be accurately positioned according to the guide pin. During blanking, two holes can be punched at the punching station until the entire material is blanked. The strip is completely flushed.

Among them, the guide pin in the die and the blanking punch should be reasonable when matching. When connecting, it should be easy to assemble and disassemble. The shape of the head of the guide pin should be convenient for the guide to be inserted into the punched hole.

2. Punching and blanking with fixed distance of guide pins

Generally, this positioning method is more commonly used for the blanking of thicker sheets and blanking parts with lower precision. During processing, it needs to be guided by the guide plate and the punch with clearance fit. However, in order to facilitate imitation, automatic stopper positioning can be used to make the feeding direction of the strip more accurate.

3. Side edge positioning

The continuous die with side edge positioning requires that the feeding step and the length of the side edge section be the same during processing, so as to ensure that the position of the hole and the shape is correct.

The above are the typical structures of the three continuous molds. No matter which structure is used, it should be operated in strict accordance with the process requirements.
