[0001] This utility model relates to the technical field of stator and rotor lamination processing equipment, and in particular to a stator and rotor lamination processing punch press. Background Technology

[0002] Laminations are made by stamping 0.3mm silicon steel sheets into laminations of different specifications to suit the stators and rotors of electric motors with different power ratings. A punch press is a type of stamping press. In national production, stamping technology has become increasingly widely used due to its advantages over traditional machining, such as saving materials and energy, high efficiency, low operator skill requirements, and the ability to produce products that cannot be achieved by machining through the application of various molds. Stamping production is mainly for sheet metal. Through molds, blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting, and extrusion parts can be produced, etc. It is widely used in various fields, such as switches and sockets, cups, cabinets, plates, computer cases, and even missiles and aircraft. Many parts can be produced by punch presses using molds.

[0003] Existing laminations are all formed by single-groove stamping, but this stamping process results in low stamping efficiency, which cannot meet production requirements. Therefore, it is necessary to design a new stamping press for stator and rotor lamination processing to solve the above problems. Utility Model Content

[0023] Example 1, referring to Figure 1-4 An embodiment of this utility model provides a stator and rotor lamination processing punch press, including a worktable 1, with a support leg 10 fixedly installed on the bottom outer surface of the worktable 1, and a housing 2 fixedly connected to the top outer surface of the worktable 1; a motor 9 is fixedly installed on the bottom inner wall of the housing 2, a rotating rod 8 is fixedly connected to the top of the output shaft of the motor 9, a rotating disk 4 is fixedly connected to the top end of the rotating rod 8, and a lamination body 3 is sleeved on the outer wall of the rotating disk 4; a column 5 is fixedly installed on the top outer surface of the worktable 1 and located behind the housing 2, a punching head 6 is movably connected to the front side of the column 5, and a connecting rod 26 is provided between the punching head 6 and the column 5; a connecting column 25 is fixedly installed on the bottom outer surface of the punching head 6, and a sliding rod 7 is fixedly connected to the bottom end of the connecting column 25.

[0024] By adopting the above technical solution:

[0025] It is convenient to drive the rotating disk 4 to rotate via the motor 9, which in turn drives the stamping body 3 on the outer wall of the rotating disk 4 to rotate, which facilitates the stamping of the stamping body 3 and improves the stamping efficiency.

[0026] Example 2, refer to Figure 3-4The outer wall of the slide rod 7 is sequentially fitted with a first slide cylinder 19, a second slide cylinder 16, and a third slide cylinder 17; a stamping die head 18 is fixedly connected to the bottom outer surface of the first slide cylinder 19, the second slide cylinder 16, and the third slide cylinder 17; a first movable rod 11 is fixedly connected to the rear side of the first slide cylinder 19, and a first rotating gear 13 is fixedly connected to the rear end of the first movable rod 11, and a first rotating shaft 14 is fixedly and movably fitted to the inner wall of the first rotating gear 13; a second movable rod 15 is fixedly connected to the rear side of the second slide cylinder 16, and a second rotating gear 20 is fixedly connected to the rear end of the second movable rod 15, and a second rotating shaft 21 is movably fitted to the inner wall of the second rotating gear 20; a first adjusting motor 12 and a second adjusting motor 22 are fixedly installed inside the stamping head 6, and a first adjusting gear 24 is fixedly fitted to the outer wall of the output shaft of the first adjusting motor 12, and a second adjusting gear 23 is fixedly fitted to the outer wall of the output shaft of the second adjusting motor 22.

[0027] By adopting the above technical solution, the output shafts of the first adjusting motor 12 and the second adjusting motor 22 can drive the first adjusting gear 24 and the second adjusting gear 23 to rotate, thereby causing the first rotating gear 13 and the second rotating gear 20 to rotate, and causing the first movable rod 11 and the second movable rod 15 to rotate, thereby adjusting the first slide cylinder 19 and the second slide cylinder 16 to adjust the spacing of the three sets of stamping dies 18 to meet different stamping conditions, thus changing single-slot stamping to multi-slot stamping.

[0028] Example 3, referring to Figure 1-4 The support leg 10 is fixedly connected to the workbench 1 by welding, which facilitates the support and fixation of the workbench 1. A round hole is opened in the middle of the punch body 3 at the position corresponding to the rotating disk 4, and the punch body 3 is locked to the rotating disk 4 through the round hole, which facilitates the rotation of the punch body 3 by the rotating disk 4. A sliding groove is opened on the outer surface of the front side of the column 5 at the position corresponding to the connecting rod 26, which facilitates the movement of the connecting rod 26 on the column 5, driving the punch head 6 to rise and fall to punch the punch body 3. The first rotating gear 13 and the second rotating gear 20 are both incomplete gears, and the first rotating gear 13 meshes with the first adjusting gear 24 and the second rotating gear 20 meshes with the second adjusting gear 23, which facilitates the operation of the punch body 3. The rotation of the first adjusting gear 24 and the second adjusting gear 23 drives the rotation of the first rotating gear 13 and the second rotating gear 20. Limiting rotation holes are opened at the bottom and top of the stamping head 6, respectively, corresponding to the positions of the first rotating shaft 14 and the second rotating shaft 21. The first rotating shaft 14 and the second rotating shaft 21 are fixedly connected to the stamping head 6, which facilitates the limiting treatment of the first rotating shaft 14 and the second rotating shaft 21. The first adjusting motor 12 and the second adjusting motor 22 are symmetrically distributed, and the output shaft of the first adjusting motor 12 and the output shaft of the second adjusting motor 22 are at the same speed and in opposite directions, which facilitates the provision of a power source for the movement of the first movable rod 11 and the second movable rod 15.

[0029] By adopting the above technical solution, it is convenient to adjust the position of the first movable rod 11 and the second movable rod 15, so that the first slide cylinder 19 on the first movable rod 11, the second slide cylinder 16 on the second movable rod 15 and the third slide cylinder 17 maintain the same distance, thus ensuring stamping accuracy.

[0030] Working principle: Refer to Figure 1-4 This utility model proposes a stator and rotor lamination processing press, which represents a significant improvement over traditional devices. When using this press, the lamination body 3 is first attached to the outer wall of the rotating disk 4. The three sets of stamping dies 18 are then adjusted as needed. The adjustment process involves starting the first adjusting motor 12 and the second adjusting motor 22. The output shafts of these motors drive the first adjusting gear 24 and the second adjusting gear 23 to rotate, which in turn drives the first rotating gear 13 and the second rotating gear 20 to rotate, ultimately causing the first movable rod 11 and the second movable rod 15 to rotate. The movement is achieved because the ends of the first movable rod 11 and the second movable rod 15 are fixedly connected to the first slide cylinder 19 and the second slide cylinder 16, which are connected on the slide rod 7. This allows the first slide cylinder 19 and the second slide cylinder 16 to slide on the slide rod 7, adjusting the spacing of the three sets of stamping die heads 18 to adapt to different conditions. Then, the motor 9 is started to drive the rotating rod 8 to rotate, which in turn drives the stamping body 3 to rotate. The power source in the column 5 (not shown in the figure) is started to drive the stamping head 6 to move up and down in a cyclical manner to stamp the stamping body 3, changing the traditional single-groove stamping to multi-groove stamping, thereby improving stamping efficiency.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
