The outer sides of the force wheel 30, the support wheel 29 and the isolation wheel 28 are meshed with a conveyor belt 26. When the plate is pulled and sent to the front end of the conveyor belt 26 at the rear, the second cylinder 12 can be turned on. The second cylinder 12 controls the gas rod to fall and drives the multiple sets of punching cylinders 14 to fall, so that the punching head 15 at the bottom fits the plate and the bottom fits the punching tube 17. Then the punching cylinder 14 drives the punching head 15 to pop up downward to punch holes in the plate. The punched waste is collected by the collection bin 18, and then the plate continues to be transported backward. The punching head 15 of the punching device can be disassembled to adapt to the apertures of different requirements. The third cylinder 2 0 Extend the gas rod to control the cutting plate 21 to fall, and cut the plate on the cutting table 22. The cut plate will continue to be driven by the conveyor belt 26 on the rear side to move backward. When the aperture is changed and becomes smaller, the required fin width will also become narrower. However, since the pulling distance of the plate is the same each time, plates with different apertures require different cutting positions. Therefore, the worker needs to control the slider 24 to slide back and forth on the second slide rail 23. When a batch of punched plates arrives at the specified position, the slider 24 moves forward to the specified position, and at this time, the operating frame and the cutting table 22 will be driven to move together. At the same time, the inner The isolation wheel 28 at the bottom will also follow the displacement, so as to ensure that the conveyor belt 26 always has a gap for the cutting table 22, first cut the excess amount of the plate head, and then move forward again to cut the plate of the required width, and at the same time start the power wheel 30 to drive the conveyor belt 26 to start and transport the cut plate backward. The plate in front will not be affected by the conveyor belt 26 due to the clamping of the rear clamping plate 10. Then the slider 24 continues to move forward to repeat the previous cutting rule, and returns to its original position after waiting for the cutting to be completed, so as to realize automatic punching and change the cutting position to cope with holes of different specifications and widths, which is practical and improves efficiency.
