A support frame 10 for limiting the threaded rod 13 and the limiting rod 19 is fixedly connected to the right surface of the base 8. A clamping assembly for clamping the workpiece is provided on the inner wall of the support frame 10. A reset assembly for resetting the support plate 7 after being subjected to force is provided at the lower end of the support plate 7. A positioning assembly for fixing the rotation arc of the shaft 16 is provided on the outer wall of the shaft 16.

[0030] Reference Figure 1 - Figure 3The clamping assembly includes a threaded rod 13 for lifting the extrusion plate 15. A rotating plate 14 is fixedly connected to the upper end of the threaded rod 13 for easy rotation. The outer wall of the threaded rod 13 is threadedly connected to the inner wall of the support frame 10. The lower end of the threaded rod 13 is rotatably connected to the extrusion plate 15 for extruding objects. A limiting rod 19 is slidably connected through the inner wall of the support frame 10 to restrict the rotation of the extrusion plate 15. The lower end of the limiting rod 19 is fixedly connected to the upper surface of the extrusion plate 15, preventing the threaded rod 13 from wobbling left and right. The outer surface of the rotating plate 14 is provided with anti-slip texture. The front surface of the base 8 is fixedly connected with a handle 9 for easy movement of the base 8 by the operator. The positioning component includes a plate 23 for inserting into the slot 17 to fix the angle. The outer wall of the rotating shaft 16 is provided with a slot 17 for accommodating the plate 23. The outer wall of the plate 23 is inserted into the inner wall of the slot 17. The front surface of the plate 23 is fixedly connected with a connecting rod 20 for connecting the pull plate 11 and the plate 23. The front surface of the connecting rod 20 is fixedly connected with a pull plate 11 for easy pushing and pulling.

[0031] Reference Figure 1 - Figure 3 A protective box 18 for protecting the internal structure and supporting the spring is fixedly connected to the right surface of the base 8. A force-applying spring 21 for continuously applying force to the insert plate 23 is fixedly connected to the inner wall of the protective box 18. The rear end of the force-applying spring 21 is fixedly connected to the outer wall of the connecting rod 20. When the connecting rod 20 is pulled outward, one end of the spring applies a force to reset the connecting rod 20. The outer wall of the insert plate 23 is slidably connected to the inner wall of the protective box 18. The connecting rod 20 is slidably connected to the inner wall of the protective box 18. Multiple sets of limiting rods 19 are provided.

The upper end of the reset spring 22 is fixedly connected to the lower surface of the support plate 7, and the lower end of the reset spring 22 is fixedly connected to the inner wall of the sleeve 6.

[0032] Working principle: First, place the workpiece on the base 8, pull open the pull plate 11, causing the pull plate 11 to drive the connecting rod 20, causing the insert plate 23 to disengage from the slot 17. At this time, the rotating shaft 16 starts to rotate. Hold the handle 9 and adjust the base 8 to a suitable angle, then release the pull plate 11 and turn the rotating plate 14, causing the threaded rod 13 to drive the pressing plate 15 to press down on the workpiece to be processed. Due to the existence of the limit rod 19, the pressing plate 15 will not rotate horizontally. At this time, turn on the equipment, causing the hydraulic rod 3 to press down and drive the bending knife 4 to extrude the workpiece into the predetermined shape. During the extrusion, due to the sinking of the force point, the support plate 7 moves downward with the deformation of the workpiece. The return spring 22 inside the sleeve 6 presses down synchronously, completing the workpiece processing. Under the action of the force spring 21 inside the protective box 18, the connecting rod 20 begins to return to its original position. Turn the rotating plate 14 in the opposite direction to make the pressing plate 15 disengage from the workpiece surface. Pull out the pull plate 11 and rotate the base 8 to return to its original position. At this time, remove the workpiece, completing the workpiece processing operation.
