DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1-5 As shown, the utility model provides a technical solution, a stamping die for easy replacement of a stamping head, comprising a lower die 1 and a hydraulic rod 2, a movable frame 3 is installed at the bottom of the hydraulic rod 2 by screws, a fixed plate 4 is installed at the bottom of the movable frame 3 by screws, a stamping head 5 is arranged at the bottom of the fixed plate 4, a rotating plate 6 is rotatably connected to the top of the stamping head 5, clamping rods 7 are installed at both ends of the top surface of the fixed plate 4 by screws, a bidirectional threaded rod 8 is rotatably connected to one end of the top of the fixed plate 4, an insertion rod 9 is threadedly connected to the outer side of the bidirectional threaded rod 8, and an insertion groove 10 is provided at the position of the rotating plate 6 corresponding to the insertion rod 9;

[0025] The insertion rod 9 is inside the insertion groove 10, and a rectangular groove is provided at the position of the fixed plate 4 corresponding to the rotating plate 6. The longitudinal section of the clamping rod 7 is L-shaped, and the top surface of the rotating plate 6 and one end surface of the clamping rod 7 are in contact with each other;

[0026] A gear rod 11 is provided at one end of the mobile frame 3, and the gear rod 11 is connected to the mobile frame 3 by a fixed screw 20, the gear rod 11 is meshed with the gear 12, the limiting telescopic rod 16 is fixedly installed at one end of the lower mold 1, and a threaded groove is provided at one end of the mobile frame 3 corresponding to the position of the fixed screw 20, one end of the lower mold 1 is rotatably connected to the gear 12, one end of the gear 12 is fixedly installed with a threaded barrel 13, the inside of the threaded barrel 13 is connected with an adjusting threaded rod 14 through a thread, one end of the adjusting threaded rod 14 is fixedly connected with a connecting plate 15, one end of the bottom of the connecting plate 15 is fixedly connected with the limiting telescopic rod 16, both ends of the connecting plate 15 are evenly rotatably connected, a spring sheet 18 is welded on the outside of the ratchet 17 inside the connecting plate 15, and a rotating roller 19 is fixedly installed at the end of the ratchet 17.

[0027] According to the size of the stamped parts, the personnel move the punching head 5 to pass the rotating plate 6 through the fixed plate 4, and then rotate the rotating plate 6 to make the rotating plate 6 rotate 90°, and rotate the two ends of the rotating plate 6 to the inside of the clamping rod 7 to preliminarily limit and fix the rotating plate 6. Then, the personnel drive the insertion rod 9 to move by rotating the two-way threaded rod 8, and move the insertion rod 9 to the inside of the insertion groove 10 to fix the rotating plate 6, thereby realizing the fixation of the punching head 5. Since the punching head 5 is in an arc state, the punching head 5 and the rotating plate 6 are movably connected, which does not affect the use of the rotating plate 6, and is convenient for personnel to install and disassemble the punching head 5, and can realize double fixation of the punching head 5, thereby improving the stability of the punching head 5 after fixation, thereby ensuring the use of the punching head 5.

[0028] Then the personnel put the material between the two lower dies 1 and the punch head 5, and pass the material through the middle of the two rotating rollers 19. According to the size of the punch head 5, the personnel adjust the position of the toothed rod 11, and then fix the fixed screw 20, so that the moving distance of the rotating roller 19 can be adjusted, and then the hydraulic rod 2 is turned on to drive the moving frame 3 and the punch head 5 to move, so as to realize the stamping of the parts. After the stamping is completed, the moving frame 3 moves up, drives the toothed rod 11 to move, and then drives the gear 12 to rotate, and the rotation of the gear 12 drives the threaded barrel 13 to rotate, and the threaded connection between the threaded barrel 13 and the adjusting threaded rod 14 drives the adjusting threaded rod 14 to move, and the movement of the adjusting threaded rod 14 drives the connecting plate 15 moves, thereby driving the rotating roller 19 to move. Since the rotating roller 19 is in contact with the surface of the part, and the use of the ratchet 17 and the spring sheet 18 prevents the rotating roller 19 from rotating in the opposite direction, at this time, there is direct friction contact between the rotating roller 19 and the part, thereby driving the part to move, realizing the feeding of the part, and facilitating the next stamping of the part. This solves the problem that in the existing life, after the stamping is completed, manual loading is required, resulting in low loading efficiency, affecting the efficiency of part stamping, and easily causing personal injury. During the stamping process, the ratchet 17 is in contact with the arc surface of the spring sheet 18, and the rotating roller 19 will rotate, causing the rotating roller 19 to rotate, facilitating the next feeding of the part.

[0029] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
