[0038] Specifically, the hydraulic cylinder 2 17 in the equipment is started, so that its output end starts to move, thereby driving the punch head 15 to descend; when the punch head 15 collides with the heat exchange plate, it will penetrate the plate and complete the first punching process; after the punching is completed, the equipment will automatically enter the next operation; the hydraulic cylinder 13 starts to work and drives the cross bar 16 to move; in this process, the slider 14 slides in the slide groove 14, plays a limiting role, and ensures the accuracy and stability of the movement of the cross bar 16; as the cross bar 16 moves, the two hydraulic cylinders 2 17 will also move backward until they reach the preset specified position. position; after reaching the specified position, the hydraulic cylinder 17 is started again to drive the punching head 15 to perform the horizontal punching process; this horizontal punching method enables the equipment to complete multiple punching tasks at one station, greatly improving the processing efficiency; when transposition punching is required, the drive motor 10 will start; the rotation of the threaded rod 9 further drives the movable plate 8 to move horizontally; the movement of the movable plate 8 drives the heat exchange plate installed on its rear side to move horizontally, thereby realizing transposition punching; this automated transposition method not only improves the processing efficiency, but also avoids the potential safety hazards caused by manual operation.

[0040] Specifically, first, when the right clamping plate 202 is pulled, the spring 203 is squeezed, thereby storing energy; in this process, the elastic potential energy of the spring 203 is gradually accumulated, preparing for the next action; as the right clamping plate 202 retracts, the left side of the heat exchange plate is smoothly inserted into the left clamping plate 208; then, when the right clamping plate 202 is released, the spring 203 begins to release the previously accumulated potential energy, pushing the right clamping plate 202 to move; this action is precise and rapid, allowing the right side of the heat exchange plate to be smoothly inserted into the right clamping plate 202; in this process, the slider 204 slides in the slide groove 205, which not only provides a stable trajectory for the movement of the right clamping plate 202, but also The smoothness and accuracy of the entire action are ensured; it is worth mentioning that the heat exchange plate can be stably clamped and installed through the symmetrically designed left clamp 208 and right clamp 202; this symmetrical design not only improves the structural stability of the equipment, but also effectively reduces the error during the installation process; while the right clamp 202 moves, the arc rod 206 will penetrate the vertical block 207; at this time, the bolt 11 is installed in the through hole 12 exposed on the arc rod 206, which further enhances the stability of the heat exchange plate after installation; this design cleverly utilizes the cooperation between the bolt 11 and the through hole 12, so that the heat exchange plate is not prone to position displacement when being stamped, thereby greatly improving the stamping accuracy of the heat exchange plate.

The position of the heat exchange plate can be punched at multiple positions, thereby improving the processing efficiency and avoiding the safety hazards caused by manual operation, which can meet the needs of use, and the right clamping plate 202 is pulled while the spring 203 is squeezed and stored, pulling the right clamping plate 202 to retract, inserting the left side of the heat exchange plate into the left clamping plate 208, and at the same time releasing the right clamping plate 202, the spring 203 extends the potential energy to push the right clamping plate 202 to move, so that the right side of the heat exchange plate is inserted into the right clamping plate 202, and the right clamping plate 202 moves while bringing The movable slider 204 slides in the slide groove 205, and the moving trajectory of the right clamping plate 202 is planned. The heat exchange plate can be stably clamped and installed through the symmetrically designed left clamping plate 208 and right clamping plate 202. When the right clamping plate 202 moves, the arc rod 206 passes through the vertical block 207. At the same time, the bolt 11 is taken and installed in the through hole 12 exposed on the arc rod 206, which further increases the stability of the heat exchange plate after installation, avoids the position deviation of the heat exchange plate during stamping, and thus increases the stamping accuracy of the heat exchange plate, which brings convenience to processing.
