[0032] The utility model provides a technical solution: Figure 1-Figure 5 As shown, in this embodiment, a high-precision stamping device includes a frame 1, a cylinder 2, a mold 3 and a punch head 15. The cylinder 2 is fixed at the middle position of the upper end of the frame 1, and the mold 3 is fixed at the middle position of the lower end of the frame 1. The lower telescopic end of the cylinder 2 passes through the frame 1 and is fixed with a fixed plate 16. The punch head 15 is fixed to the right side of the lower end of the fixed plate 16. The punch head 15 is located directly above the mold 3. A positioning assembly is arranged on the fixed plate 16 on the left side of the punch head 15. A driving assembly is fixed to the lower right side of the frame 1 by bolts, and a cleaning assembly is installed on the right side of the driving assembly.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, the positioning assembly includes a U-shaped rod 17 that passes through the left part of the fixed plate 16. The front and rear ends of the U-shaped rod 17 are both equipped with positioning sleeves 18. The interior of the positioning sleeve 18 is connected to the end of the U-shaped rod 17 through a first spring. The positioning sleeve 18 is located on the upper side of the mold 3. The positioning sleeve 18 is driven down during the process of the cylinder 2 driving the punch head 15 to descend. The positioning sleeve 18 first contacts the left part of the material. As the cylinder 2 continues to press down, the U-shaped rod 17 will squeeze the first spring inside the positioning sleeve 18, while providing a descending space for the punch head 15, the positioning sleeve 18 can better press the material.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, the driving assembly includes a lower mounting seat 11 fixed to the lower right side of the frame 1 and an upper mounting seat 4 installed on the upper side of the lower mounting seat 11, a lower roller 20 is rotatably connected inside the lower mounting seat 11, and the horizontal tangent of the vertex of the lower roller 20 is at the same height as the upper end surface of the mold 3, and the upper mounting seat 4 and the lower mounting seat 11 are integrally formed with a pressing edge at the front and rear ends, and a guide rod passes through the front and rear pressing edges of the upper mounting seat 4, and the other end of the guide rod is fixedly connected to the pressing edge of the lower mounting seat 11 and a second spring is sleeved on the guide rod, and the front and rear pressing edges of the lower mounting seat 11 are both threadedly connected with an adjusting screw 12, and the top of the adjusting screw 12 is rotatably connected to the pressing edge of the upper mounting seat 4 through a bearing, and a servo motor 13 is fixed to the front side of the upper mounting seat 4. The inner output shaft of the servo motor 13 is connected to an upper roller 19, and the upper roller 19 is rotatably connected to the upper mounting seat 4. The upper roller 19 is located just above the lower roller 20. A controller is fixed to the upper end of the upper mounting seat 4. The controller is electrically connected to the cylinder 2 and the servo motor 13 through wires. The servo motor 13 can be regulated by the controller to ensure the orderly operation of the servo motor 13. The rotation of the servo motor 13 drives the upper roller 19 to rotate, so that the material between the upper roller 19 and the lower roller 20 can be fed. At the same time, when the operation stops, the material can also be pressed to avoid shaking during the stamping process, thereby ensuring accurate feeding and reducing manual operation.

[0035] like Figure 1-Figure 3 As shown, the cleaning assembly includes an upper cleaning frame 5 installed on the right side of the upper mounting seat 4 and a lower cleaning frame 10 installed on the right side of the lower mounting seat 11, and the upper end of the upper cleaning frame 5 and the lower end of the lower cleaning frame 10 are symmetrically fixed with fixing strips 14, and the upper mounting seat 4 and the lower mounting seat 11 are correspondingly fixed with fixing seats, the fixing strip 14 passes through the fixing seat and the top of the fixing seat is connected with bolts through threads, and the bolts pass through the fixing seat and contact the fixing strip 14, and the interior of the upper cleaning frame 5 and the lower cleaning interior are both bonded and fixed with a cleaning brush 9 through a fixing plate 16, and the height of the cleaning brush 9 on the lower side is higher than the height of the lower roller 20. By using the set cleaning assembly, the upper and lower surfaces of the material can be cleaned, and the bonded foreign matter can be brushed off to avoid affecting the stamping effect. At the same time, the cleaning brush 9 on the upper side can be adjusted in height following the upper mounting frame, and the set fixing strip 14 is used to facilitate regular replacement and cleaning of the cleaning brush 9.

[0036] like Figure 2-4As shown, a hanging rod 6 is welded and fixed on the right side of the upper cleaning frame 5, and two groups of adjusting nuts 7 are threadedly connected to the hanging rod 6. Two groups of limiting strips 8 are installed on the hanging rod 6 inside the two groups of adjusting nuts 7. A third spring is installed on the hanging rod 6 between the limiting strip 8 and the adjusting nut 7. The end of the third spring away from the adjusting nut 7 is fixedly connected to the side of the limiting strip 8. Limiting grooves are provided on the front and back sides of the hanging rod 6, and a protrusion matching the limiting groove is integrally formed inside the limiting strip 8. The setting of the limiting strip 8 cooperates with the third spring to limit the material from both sides, so as to ensure that the material is not offset during the feeding process. The setting of the adjusting nut 7 can be used to flexibly adjust the position of the limiting strip 8 as needed, thereby improving the accuracy of stamping.

[0037] The utility model provides a specific working principle as follows: during normal use, the design is first connected to electricity, and then one end of the material to be punched is placed on the cleaning brush 9 located on the lower side, and the height of the upper mounting frame is lowered by rotating the adjusting screw 12, thereby lowering the height of the upper cleaning frame 5, so that the cleaning brush 9 located on the upper side can fit the upper surface of the material, and then the material is continued to be pushed, and the position of the upper roller 19 is adjusted so that the upper roller 19 can contact the upper surface of the material, and the upper roller 19 is driven by the servo motor 13, so that the material can be driven in conjunction with the lower roller 20 to feed the material until the specified length, during the feeding process, the cleaning brush 9 brushes off foreign matter on the surface of the material, and then the cylinder 2 is operated, and the cylinder 2 pushes the fixed plate 16 to move downward, and the fixed plate 16 drives the punch head 15 to move downward, and at the same time drives the positioning assembly to move downward, and during the movement, the positioning sleeve 18 contacts the end of the material away from the driving assembly, and as the cylinder 2 continues to run, the first spring will be squeezed, so that the positioning sleeve 18 presses the end of the material, and finally the punch head 15 is used to complete the punching.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
