Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a reversible forming knife, including a fixed frame 1. A groove is formed at the bottom left side of the fixed frame 1. A reciprocating screw 8 is rotatably connected to the inner wall of the groove. A sliding connecting block 4 is provided on the outer wall of the reciprocating screw 8. A drive ring 9 is fixedly connected to the top of the reciprocating screw 8. A drive rod 10 is fixedly connected to the bottom of the drive ring 9. A rotating ring 7 is fixedly connected to the top of a telescopic rod 3. The telescopic rod 3 is used to accommodate the sliding connecting block 4 sliding up and down. The top of the rotating ring 7 has four rotating grooves, the inner wall of which is connected to the drive rod 10. The outer wall of ring 9 is engaged with the rotating ring 7, which has four drive grooves at its top. The inner wall of the drive grooves abuts against the outer wall of the drive rod 10 to enable the telescopic rod 3 and the reciprocating screw 8 to rotate synchronously. A servo motor 2 is fixedly connected to the top of the fixed frame 1. The drive end of the servo motor 2 is fixedly connected to the top of the driving ring 9. When working, the servo motor 2 is started, causing the driving ring 9 to drive the reciprocating screw 8 to rotate. The rotation of the reciprocating screw 8 causes the sliding connecting block 4 to slide up and down in the groove. At the same time, the driving ring 9 drives the drive rod 10 to make the rotating ring 7 rotate intermittently. This allows the blade to flip after moving up and down once, driven by the rotating ring 7 and the telescopic rod 3, which rotates the tool sleeve 5. This avoids tool wear due to prolonged use, improves tool life, reduces production costs, and allows for higher machining accuracy.

[0026] Reference Figure 1 , Figure 4 and Figure 6A blade sleeve 5 is rotatably connected to the bottom left side of the sliding connecting block 4. The top of the blade sleeve 5 is fixedly connected to the bottom of the telescopic rod 3. An adjusting disc 6 is connected to the top of the inner wall of the blade sleeve 5 via a damping shaft. A connecting disc 12 is rotatably connected to the bottom of the adjusting disc 6. The outer wall of the connecting disc 12 is fixedly connected to the inner wall of the blade sleeve 5. Multiple adjusting sliders 14 are slidably connected to the inner wall of the connecting disc 12. The bottom ends of the multiple adjusting sliders 14 on the adjacent side are fixedly connected to the top ends of the multiple fixed ring blocks 13 on the opposite side. Adjusting rods 15 are fixedly connected to the top ends of the multiple adjusting sliders 14 on the adjacent side. Figure 5 The bottom of the adjusting plate 6 has multiple arc-shaped adjusting grooves. The inner wall of the arc-shaped adjusting grooves is slidably connected to the outer wall of the adjusting slide rod 15 to control the spacing of multiple fixed ring blocks 13. An adjusting ring 11 is fixedly connected to the outer wall of the adjusting plate 6 for easy gripping. When it is necessary to change the tool, turn the adjusting ring 11 to rotate the adjusting plate 6. The rotation of the adjusting plate 6 drives the adjusting slide rod 15 to make the adjusting slider 14 slide on the inner wall of the connecting plate 12. The adjusting slider 14 drives the multiple fixed ring blocks 13 to slide, so as to adjust the spacing of the multiple fixed ring blocks 13 to accommodate the fixing of tools of different specifications.

[0027] Working principle: During operation, the servo motor 2 is activated, causing the drive ring 9 to rotate the reciprocating screw 8. The rotation of the reciprocating screw 8 causes the sliding connecting block 4 to slide up and down reciprocally within the slide groove. Simultaneously, the drive ring 9 drives the drive rod 10 to intermittently rotate the rotating ring 7. This causes the cutting tool to flip after each upward and downward movement, driven by the rotating ring 7 and the telescopic rod 3, which rotates the tool sleeve 5. This prevents tool wear over prolonged use, increases tool life, reduces production costs, and achieves higher machining accuracy. When tool replacement is required, the adjusting ring 11 is turned to rotate the adjusting disc 6. The rotation of the adjusting disc 6 causes the adjusting slide rod 15 to slide the adjusting slider 14 on the inner wall of the connecting disc 12. The adjusting slider 14 drives multiple fixed ring blocks 13 to slide, adjusting the spacing of the multiple fixed ring blocks 13 to accommodate different sizes of cutting tools.
