[0004] However, the existing processing equipment has the following shortcomings: Existing equipment often directly performs the punching step during the processing process, and lacks constraints on the workpiece. Since the workpiece is subjected to a large force during the punching process, when the workpiece lacks constraints and is directly processed by the equipment, the workpiece will deviate during the processing process, resulting in deformation of the structure of the punching part and reduced strength of the notch part.

[0010] Preferably, the number of columns is four, and the four columns are arranged in a circular array about the hydraulic cylinder. The connecting sleeve matches the number of columns, and the compression spring matches the number of columns. Through the cooperation between the column and the connecting sleeve, the deformation direction of the compression spring can be guided to avoid the possibility of deviation in the deformation direction of the compression spring.

[0011] Preferably, the compression spring is socketed with the surface of the column, the compression spring is socketed with the surface of the connecting sleeve, the extrusion block is located directly above the load-bearing block, the load-bearing block is trapezoidal, and the position of the pressure plate can be constrained by the compression spring under the action of the connecting frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a linkage unit and a punching unit. When processing is performed, the loading robot places the workpiece above the mold. When the loading robot places the workpiece and leaves the processing area, the fuselage controls the hydraulic cylinder to work. The hydraulic cylinder pushes the connecting frame downward. Under the action of the column, the connecting sleeve and the compression spring, the connecting frame pushes the pressure plate and the extrusion block downward. The pressure plate is forced to move downward to the top of the workpiece and press the workpiece downward, thereby clamping the workpiece in cooperation with the mold below the workpiece. When the pressure plate clamps the workpiece, the hydraulic cylinder continues to push the connecting frame downward, and the connecting frame moves downward, and continues to push the compression spring, the column and the extrusion block. The compression spring is deformed under the force of the pressure plate, and the column is pushed to slide into the connecting sleeve. The extrusion block is pushed to continue to move downward, and contacts the inclined surface of the load-bearing block during the movement, thereby squeezing the load-bearing block. Under the action of its own inclined surface and the extrusion block, the load-bearing block is forced to push the punching cutter head in the direction of the workpiece. At the same time, the slider is pushed by the load-bearing block and squeezes the reset spring under the guidance of the guide column and the damping sleeve. The reset spring is squeezed and deformed, and the punching cutter head moves toward the workpiece during the pushing process, thereby cooperating with the mold to punch the workpiece. By setting the linkage unit and the punching unit, the equipment can clamp the workpiece before punching, thereby avoiding the workpiece from being offset during the punching process, resulting in structural deformation of the punching part, and causing the problem of reduced strength, thereby further improving the processing effect of the equipment on the workpiece.

[0017] 2. The present invention sets a waste conveying unit. When the equipment is working, the machine body supplies power to the servo motor, and the servo motor rotates the drive shaft clockwise when powered on. The drive shaft cooperates with the roller to rotate the conveyor belts on both sides. When the equipment completes punching and the punching cutter head is reset, the machine body controls the blowing mechanism to work, and the blowing mechanism cooperates with the air hole to blow air into the punching cutter head, thereby blowing out the waste in the punching cutter head. The blown waste falls onto the conveyor belt. During the rotation of the conveyor belt, it cooperates with baffle 1 and baffle 2 to send the waste on its surface out of the processing area. By setting the waste conveying unit, the waste generated during the equipment processing can be quickly sent out of the processing area, thereby improving the working efficiency of the equipment.

[0030] The effect achieved by the entire mechanism is as follows: during processing, the loading robot places the workpiece above the mold 2. When the loading robot places the workpiece and leaves the processing area, the fuselage 1 controls the hydraulic cylinder 4 to work. The hydraulic cylinder 4 pushes the connecting frame 611 downward. Under the action of the column 612, the connecting sleeve 613 and the compression spring 614, the connecting frame 611 pushes the pressure plate 615 and the extrusion block 616 downward. The pressure plate 615 is forced to move downward to the top of the workpiece and press the workpiece downward, thereby clamping the workpiece with the mold 2 below the workpiece. When the pressure plate 615 clamps the workpiece, the hydraulic cylinder 4 continues to push the connecting frame 611 downward. The connecting frame 611 moves downward and continues to push the compression spring 614, the column 612 and the extrusion block 616. The compression spring 614 is deformed under the force of the pressure plate 615, and the column 612 is pushed to slide into the connection The extrusion block 616 is pushed to continue to move downward, and contacts the inclined surface of the load-bearing block 623 during the movement, thereby extruding the load-bearing block 623. Under the action of its own inclined surface and the extrusion block 616, the load-bearing block 623 is forced to push the punching cutter head 624 in the direction of the workpiece. At the same time, the slider 622 is pushed by the load-bearing block 623, and under the guidance of the guide column 627 and the damping sleeve 628, the reset spring 625 is squeezed and deformed. The punching cutter head 624 moves toward the workpiece during the pushing process, thereby cooperating with the mold 2 to punch the workpiece. By setting the linkage unit 61 and the punching unit 62, the device can clamp the workpiece before punching, thereby avoiding the workpiece from being offset during the punching process, resulting in structural deformation of the punching part, and causing the problem of reduced strength, thereby further improving the processing effect of the device on the workpiece; In addition, when the equipment is working, the body 1 supplies power to the servo motor 633, and the servo motor 633 is powered on to rotate the drive shaft 632 clockwise, and the drive shaft 632 cooperates with the roller to rotate the conveyor belts 636 on both sides; when the equipment completes punching and the punching head 624 completes resetting, the body 1 controls the blowing mechanism 5 to work, and the blowing mechanism 5 cooperates with the air hole 629 to blow air into the punching head 624, thereby blowing out the waste in the punching head 624, and the blown waste falls onto the conveyor belt 636. During the rotation of the conveyor belt 636, it cooperates with the baffle 1 637 and the baffle 2 638 to send the waste on its surface out of the processing area. By setting the waste conveying unit 63, the waste generated during the equipment processing can be quickly sent out of the processing area, thereby improving the working efficiency of the equipment.
