[0018] The following is only a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions under the concept of the present invention should fall within the scope of protection of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figures 1 to 4 The tool box 1 is provided with two movable parts, and the movable part 4 is fixed with the movable part 4 at the bottom end of the tool box 1. The movable part 4 is connected with the movable part 4 to the movable part 4 at the bottom end of the tool box 1. The movable part 4 is connected with the movable part 4 to the movable part 4 at the bottom end of the tool box 1.

[0020] The moving mechanism 6 includes two threaded rods 18, which are rotatably inserted into the cavity 5. A threaded seat 26 is inserted into each threaded rod 18. The lower ends of the two connecting blocks 4 are fixedly connected to the upper ends of the two threaded seats 26. A bevel gear a19 and a bevel gear b20 are fixed on the two threaded rods 18, and the bevel gear a19 and the bevel gear b20 are meshed. A turning handle 21 is provided on one side of the processing table 1. One end of the threaded rod 18 passes through the processing table 1 and is fixedly connected to one end of the turning handle 21. By turning the handle 21, one of the threaded rods 18 can be driven to rotate, thereby driving the bevel gear a19 to rotate. Since the bevel gear a19 and the bevel gear b20 are engaged, the rotation of the bevel gear a19 can drive the bevel gear b20 and the other threaded rod 18 to rotate simultaneously, and ultimately the two threaded rods 18 can be rotated simultaneously. Therefore, the two threaded seats 26 can be moved simultaneously along the two threaded rods 18, so as to drive the two connecting blocks 4 to slide along the slide groove 3, and ultimately the two stoppers 2 can be driven to move simultaneously.

[0021] Two pillars 10 are fixed to the upper end of the processing table 1, and a mounting plate 11 is fixed to the upper end of the two pillars 10. A hydraulic cylinder 12 is installed on the upper end of the mounting plate 11, and a fixed seat 13 is provided below the mounting plate 11. The output shaft of the hydraulic cylinder 12 passes through the mounting plate 11 and is fixedly connected to the upper end of the fixed seat 13. The fixed seat 13 can be driven up and down by the output shaft of the hydraulic cylinder 12. A fixing sleeve 14 is fixed to the lower end of the fixing seat 13, and a slidable limiting sleeve 15 is passed through the lower end of the fixing sleeve 14. A limiting mechanism 16 is set in the fixing sleeve 14, and the limiting mechanism 16 is connected to the limiting sleeve 15. A detachable stamping die 17 is also installed at the lower end of the fixing seat 13, and the stamping die 17 is located in the fixing sleeve 14. When the metal gasket to be processed is placed on the processing table 1, the fixing seat 13 can be moved downward to drive the fixing sleeve 14 and the limiting sleeve 15 to move downward at the same time, and then the limiting sleeve 15 can be made to fit the surface of the metal gasket. As the fixing seat 13 continues to move downward, the top end of the limiting sleeve 15 can slide upward along the inside of the fixing sleeve 14, and then the stamping work of the metal gasket can be completed by the stamping die 17. When the limiting sleeve 15 slides upward along the inside of the fixed sleeve 14, the metal gasket can be pressed and fixed by the limiting mechanism 16 to prevent the metal gasket from shifting during the stamping process, thereby ensuring the stamping effect of the metal gasket and further increasing the processing efficiency of the metal gasket.

[0022] The limiting mechanism 16 includes several limiting springs 22, and a limiting groove 23 is provided at the lower end of the fixed sleeve 14. The upper end of the limiting sleeve 15 can be slidably located in the limiting groove 23. The upper ends of several limiting springs 22 are respectively fixed to the top of the limiting groove 23, and the lower ends are respectively fixedly connected to the upper end of the limiting sleeve 15. When the top of the limiting sleeve 15 slides upward along the limiting groove 23, the several limiting springs 22 can be squeezed to generate elastic force. Therefore, the elastic force generated by the limiting spring 22 can be applied to the upper surface of the metal gasket, thereby achieving the effect of pressing and fixing the metal gasket. When the metal gasket is stamped, the limiting sleeve 15 can be driven back to the initial position by the reset effect of the limiting spring 22 to facilitate the next stamping work.

[0023] A plurality of fixing pins 24 are pierced through the side wall of the fixing seat 13, and a mounting hole is provided on the lower side of the fixing seat 13, and the upper end of the stamping die 17 is located in the mounting hole, and the top ends of the plurality of fixing pins 24 are respectively located in the stamping die 17, and each fixing pin 24 is pierced with a reset spring 25, and the two ends of the reset spring 25 are connected between the outer wall of the fixing seat 13 and the tail end of the fixing pin 24. The staff can replace the stamping die 17 according to the metal gaskets of different specifications, so as to facilitate the replacement of the appropriate stamping die 1 7 punches out the corresponding inner holes. At this time, the staff can pull the several fixing pins 24 so that the top ends of the several fixing pins 24 are disengaged from the stamping die 17. At this time, the reset spring 25 is squeezed to generate elastic force, and then the stamping die 17 can be disassembled and replaced. When replacing the new stamping die 17, the reset effect of the reset spring 25 can drive the several fixing pins 24 to be pushed into the stamping die 17 again to fix the stamping die 17, thereby completing the replacement of the stamping die 17.

[0024] A waste hole 7 is provided on the upper surface of the processing table 1, and a waste port 8 is provided on one side of the processing table 1, and the waste hole 7 cooperates with the waste port 8. A waste box 9 is provided on one side of the processing table 1, and the waste box 9 is located below the waste port 8. When the metal gasket is stamped, the waste chips generated by stamping its inner hole can fall into the waste hole 7, and then can fall into the waste box 9 through the waste port 8 for collection. Therefore, the stamped metal gasket can be separated from the waste chips, thereby saving the staff's sorting time and further improving the processing efficiency of the metal gasket.

[0025] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention.
