[0032] Referring to Figure 2 and Figure 4The inner wall of the workbench 1 is slidably connected with a waste groove 22 for collecting the debris generated during the machining. The inner wall of the supporting plate 5 is fixedly connected with a sleeve 14. The inner wall of the sleeve 14 is rotatably connected with a knob 15. The inner side of the knob 15 is fixedly connected with a rectangular plate 20. Rotating the knob 15 can drive the rectangular plate 20 to rotate. The inner wall of the sleeve 14 is elastically connected with an extrusion block 17 through a return spring b16. One end of the return spring b16 is fixedly connected with the outer wall of the extrusion block 17. The other end of the return spring b16 is fixedly connected with the inner wall of the sleeve 14. The surface of the extrusion block 17 is provided as an inclined surface. The side wall of the rectangular plate 20 is in contact with the inclined surface of the extrusion block 17. The rotation of the rectangular plate 20 can extrude the inclined surface of the extrusion block 17 to make it extrude the return spring b16 to move outward. At the same time, the return spring b16 generates a repulsive force to the extrusion block 17 due to the deformation, so as to facilitate the reset of the extrusion block 17. The side wall of the extrusion block 17 is provided with a rectangular protruding structure embedded in the inner wall of the sleeve 14 to prevent the extrusion block 17 from rotating and deviating during the movement.

When the rectangular plate 20 is rotated to be clamped in the notch 21, the limiting block 18 is extended outward to the maximum state and clamped in the limiting groove 19 to fix the bottom plate 6. When the limiting block 18 and the limiting groove 19 are disengaged, the bottom plate 6 can be tilted through the handle behind the bottom plate 6, so that the debris generated during the machining can quickly slide into the waste groove 22, and the cleaning is convenient.

[0033] Working principle: Place the raw materials on the mold 8. Start the hydraulic pump 3 to make the top plate 4 drive the punch 7 to descend to stamp the materials. When the mold 8 or the punch 7 is worn out after long-term use, pull out the two groups of pull rods 13 to make the clamping block 12 out of the clamping groove 10. At this time, the punch 7 or the worn-out mold 8 can be disassembled. The new punch 7 or the plug 9 at the bottom of the mold 8 is inserted into the insertion slot 23 to be fixed. No additional auxiliary tools are needed for disassembly and assembly, which is convenient. When the debris generated during the machining needs to be cleaned, rotate the knob 15 to make the rectangular plate 20 slide out of the notch 21. The return spring b16 pushes the extrusion block 17 to move inward in the sleeve 14, drives the limiting block 18 to be retracted, and disengages the limiting groove 19. At this time, the handle can be used to turn over the bottom plate 6, so that the waste generated during the machining can slide into the waste groove 22, and the cleaning is convenient.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
