[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a multi-station progressive die for processing high-voltage circuit breaker frames, including a die body 7. From left to right, the die body 7 has a first station 1, a second station 2, a third station 3, a fourth station 4, a fifth station 5, and a sixth station 6. The first station 1, second station 2, third station 3, fourth station 4, fifth station 5, and sixth station 6 are all inclined and distributed along the length of the die body 7. The inclined arrangement reduces the gap between adjacent stations, thereby reducing the die volume and allowing for full utilization of the material. A first cutting punch 9 is located to the right of the first station 1 and above the second station 2. The first cutting punch 9 cuts the short left side and bottom of the workpiece. The second station 2... A second cutting punch 10 is provided between the second station 2 and the third station 3. The second cutting punch 10 cuts the left oblique edge and the right side of the workpiece. A third cutting punch 11 is provided below the second station 2. The third cutting punch 11 cuts the top and the right side of the workpiece. A fourth cutting punch 12 is provided above the fifth station 5. The fourth cutting punch 12 cuts the bottom of the workpiece. A fifth cutting punch 13 and a seventh cutting punch 16 are provided between the fifth station 5 and the sixth station 6, respectively. The fifth cutting punch 13 cuts the bottom and the upper left end of the workpiece. The seventh cutting punch 16 cuts the right side and the long left side of the workpiece. A sixth cutting punch 14 is provided below the fifth station 5. The sixth cutting punch 14 cuts the top of the workpiece.

[0027] The first workstation 1 is equipped with two first rough punches 101. The first rough punches 101 perform rough punching on the workpiece to remove most of the material, leaving sufficient machining allowance for the subsequent first fine punches 34 to perform fine punching. This avoids excessive burrs on the material caused by a single punching, thereby ensuring the punching quality. The two first rough punches 101 are on the same straight line.

[0028] The second workstation 2 is equipped with two second rough punches 21 and two first intermediate punches 22. The second rough punches 21 perform rough punching on the workpiece to leave sufficient machining allowance for the subsequent fine punches 31 to perform fine punching, thereby improving the quality of the workpiece. The first intermediate punches 22 perform punching on the workpiece.

[0029] The third station 3 is equipped with two second fine punches 31, two first small punches 32, two first fine punches 34 and a first large punch 33. The second fine punches 31 perform fine punching on the workpiece. The two first fine punches 34 are on the same straight line as the two first coarse punches 101, and the diameter of the two first fine punches 34 is larger than the diameter of the two first coarse punches 101. The two second fine punches 31 are on the same straight line as the adjacent second coarse punches 21.

[0030] The fourth station 4 is equipped with multiple second small punches 41 and second medium punches 42. Both the second small punches 41 and the second medium punches 42 are used to punch holes in the workpiece.

[0031] Among them, the fifth station 5 is equipped with multiple third small punches 51, which are used to punch holes in the workpiece.

[0032] The first station 1 is equipped with a third auxiliary punch 17 above it. The third auxiliary punch 17 punches holes in the workpiece so that the fourth cutting punch 12 can punch it in the future, thereby reducing the deformation of the workpiece and improving the quality of the workpiece. The first auxiliary punch 8 is equipped with a first auxiliary punch 8 below it. The first auxiliary punch 8 punches holes in the workpiece to prevent the third cutting punch 11 from having too much stress during the punching process, which would affect the punching quality of the workpiece.

[0033] Two auxiliary punches 15 are provided between the first station 1 and the second station 2. The auxiliary punches 15 punch the workpiece to remove part of the material and prevent the material from being excessively deformed during the subsequent seventh cutting punch 16 punching process.

[0034] Specifically, during the punching process, the workpiece moves to the first station 1 under the action of the external conveying equipment. The first rough punch 101, the third auxiliary punch 17, the second auxiliary punch 15, and the first auxiliary punch 8 punch holes, and the first trimming punch 9 cuts the short side of the left side of the workpiece. The workpiece moves to the second station 2, where the first intermediate punch 22 and the second rough punch 21 punch holes. The first trimming punch 9 cuts the bottom of the workpiece, the second trimming punch 10 cuts the oblique side of the left side of the workpiece, and the third trimming punch 11 cuts the top of the workpiece. Subsequently, the workpiece moves to the third station 3, where the first fine punch 34 performs fine punching on the rough holes punched by the first rough punch 101, and the second fine punch 31 punches the holes punched by the second rough punch 21. The rough punched holes are then fine punched. The first small punch 32 and the first large punch 33 punch holes. The workpiece continues to move to the fourth station 4, where the second small punch 41 and the second medium punch 42 punch holes. After punching, the workpiece moves to the fifth station 5, where the third small punch 51 punches holes. The fourth cutting punch 12 cuts the bottom of the workpiece, the fifth cutting punch 13 cuts the upper left end of the workpiece, and the seventh cutting punch 16 cuts the long left side of the workpiece. The top of the workpiece is cut at the fifth station 5. Finally, the workpiece moves to the sixth station 6, where the fifth cutting punch 13 cuts the bottom of the workpiece, and the seventh cutting punch 16 cuts the right side of the workpiece, separating the workpiece from the workpiece. This completes the punching of the workpiece.
