AI Technical Summary

Problems solved by technology

The traditional silicon steel sheet cutting line has the following disadvantages: 1. The longitudinal length of the feeding channel of the silicon steel sheet cutting line is generally several meters, and the feeding device is set at the starting point of the feeding channel, and the feeding distance is long. Each roll of silicon steel sheet is several meters long. waste, wasted material

2. The feeding device adopts push-type feeding, and the conveying distance is long. When the silicon steel sheet to be conveyed is narrow or thin, deformations such as twisting and swelling are prone to occur during the feeding process, and it is difficult to increase the feeding speed

3. The distance between the feeding device and the shearing device is relatively long, and the cutting accuracy will be affected after long-distance feeding

The three-step operation of the traditional silicon steel sheet cutting line restricts the improvement of silicon steel sheet production efficiency

5. The shearing device of the traditional silicon steel sheet cross-cutting line is generally fixed, and the shearing angle cannot be adjusted, so the scope of application is narrow

6. The material collecting device of the traditional silicon steel sheet cross-cutting line is high-speed discharge. After the silicon steel sheet flies out of the conveyor belt, the silicon steel sheet is pressed down by the lower pressing block from top to bottom, so that it falls to the set position, but this method The safety is low, and the silicon steel sheets collected at the same time are not neat, and need to be stacked and sorted by manpower, which affects efficiency and wastes human resources

[0004] In the process of punching, punching V-mouth and shearing the silicon steel sheet, the above-mentioned cross-cutting line equipment, for the punching device, V-mouth shearing device and pendulum shearing device, by designing the V-mouth shearing device to be laterally movable , so that the punching device and the V-mouth shearing device can realize synchronous punching work, but for the shearing action between the punching device and the pendulum shearing device or the V-mouth shearing device and the pendulum shearing device, it is still necessary to For distributed cutting, the work efficiency is still not very high. In addition, the lateral distance between the two punching devices is fixed, so that when punching holes on silicon steel sheets of different specifications, it is still necessary to carry out separate operations. Step punching increases the shearing time required for the same silicon steel sheet and reduces work efficiency
