Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to a motor stator and rotor slotting die. Background Technology

[0002] In the process of motor manufacturing, the stator and rotor are the main internal structures of the motor. During the production process, the stator and rotor of the motor are combined by laminating and riveting thin sheets. Therefore, in order to obtain thin sheets of a specified shape, the raw material sheet is stamped, which requires the use of motor stator and rotor slotting dies.

[0003] Existing motor stator and rotor slotting dies are prone to deformation during stamping due to downward pressure and friction between the sheet metal and the die during upward return. This prevents the sheet metal from adhering tightly to the lower die base, thus reducing stamping quality. When using a quick-lock riveting method, grooves need to be punched downwards into the stamped sheet metal, but the sheet metal cannot be penetrated. Therefore, the riveting head needs to extend downwards to a suitable length. The length of the downward extension of the riveting head varies depending on the thickness of the sheet metal. Traditional punches cannot adjust the length of the downward extension of the riveting head, requiring the replacement of the entire punch, which reduces stamping efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems that the above-mentioned sheet metal is prone to deformation during the stamping process, which makes the sheet metal unable to fit tightly against the lower die base, thereby reducing the stamping quality, and that the traditional punch cannot adjust the downward extension length of the rivet head, and can only replace the entire punch, which is more time-consuming and labor-intensive. This utility model provides a motor stator and rotor slotting die.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A motor stator and rotor slotting die includes a lower die base, an upper die base, and a limiting sleeve. The upper and lower die bases are distributed vertically and are slidably connected by the limiting sleeve. A left punch is fixedly installed inside the left side of the upper die base, and a right punch is slidably connected inside the right side of the upper die base. Rivet heads are uniformly fixed inside the right side of the upper die base. A threaded rod is rotatably connected above the right punch inside the right side of the upper die base, and the threaded rod extends downward to the center of the top of the right punch and is threadedly connected to the right punch. Therefore, during the rotation of the threaded rod, the right punch can be moved up and down. An installation groove is provided at the center of the bottom of the upper die base. Inclined plates are symmetrically hinged to the left and right sides of the bottom of the installation groove. Rollers are rotatably connected to the bottom of each inclined plate. Springs are fixedly connected between the left and right inclined plates.

[0006] Furthermore, the rivet head extends downward through the right punch to the lower side of the right punch, and the right punch is slidably connected to the rivet head at both the upper and lower limits, so that the right punch can be adjusted up and down relative to the rivet head.

[0007] Furthermore, an internal hexagon block is fixedly connected to the top of the threaded rod, and the internal hexagon block extends upward to the top of the upper mold base, so that the threaded rod can be driven to rotate by the cooperation of a wrench and the internal hexagon block at the top of the upper mold base.

[0008] Furthermore, the inclined plates on the left and right sides unfold symmetrically from top to bottom, so that as the upper mold base moves downward, the inclined plates can unfold to both sides on the plate.

[0009] Furthermore, fastening bolts are threaded onto the outer sides of the left and right punches on both sides of the upper die holder. The fastening bolts are evenly distributed on the outer sides of the left and right punches and are fixed to the left and right punches by pressing them inward.

[0010] Furthermore, a plate is placed above the lower mold base, and the plate moves from left to right to perform grooving and lamination.

[0011] The beneficial effects of this utility model are as follows: This invention utilizes a design with an inclined plate and rollers between the left and right punches at the bottom of the upper die base. During the downward movement of the upper die base for stamping, the inclined plate drives the rollers to roll and spread out on both sides of the upper surface of the sheet metal. This allows the sheet metal to better adhere to the upper surface of the lower die base, ensuring stamping quality. Furthermore, by using a rotating threaded rod to adjust the up and down movement of the right punch, the length of the rivet head extending downward from the bottom of the right punch can be adjusted. This allows for quick-locking riveting assembly of sheet metal of different thicknesses after stamping, eliminating the need to replace the entire punch and improving stamping efficiency.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0015] A preferred embodiment of the present invention, a motor stator and rotor slotting die, will be described in detail below, as follows: Figures 1-7 As shown, a motor stator and rotor slotting die includes a lower die base 1, an upper die base 2, and a limiting sleeve 3. The upper die base 2 and the lower die base 1 are distributed vertically and are connected by the limiting sleeve 3. A left punch 4 is fixedly installed inside the left side of the upper die base 2, and a right punch 5 is slidably connected inside the right side of the upper die base 2. Rivet heads 6 are evenly fixedly installed inside the right side of the upper die base 2. The rivet heads 6 penetrate the right punch 5 and extend downward to the lower side of the right punch 5. The right punch 5 is slidably connected to the rivet head 6 in a vertically limited manner, so that the right punch 5 can be adjusted vertically relative to the rivet head 6.

[0016] A threaded rod 7 is rotatably connected to the upper limit of the right punch 5 inside the right side of the upper die base 2. The top of the threaded rod 7 is fixedly connected to an internal hexagon block 71, which extends upward to the top of the upper die base 2. This allows the threaded rod 7 to be driven to rotate by the cooperation of a wrench and the internal hexagon block 71 at the top of the upper die base 2. The threaded rod 7 extends downward to the center of the top of the right punch 5 and is threadedly connected to the right punch 5. Therefore, during the rotation of the threaded rod 7, the right punch 5 can be moved up and down.

[0017] A plate 13 is placed on top of the lower mold base 1. The plate 13 moves from left to right to perform grooving and lamination. An installation groove 8 is provided in the center of the bottom of the upper mold base 2. Sloping plates 9 are symmetrically hinged on the left and right sides of the bottom of the installation groove 8. The left and right sloping plates 9 unfold symmetrically from top to bottom, so that the sloping plates 9 can unfold on the plate 13 to both sides during the downward movement of the upper mold base 2. Rollers 10 are connected to the bottom of the sloping plates 9 for limiting rotation. Springs 11 are fixedly connected between the left and right sloping plates 9.

[0018] The left punch 4 and right punch 5 on both sides of the upper die base 2 are threaded with fastening bolts 12. The fastening bolts 12 are evenly distributed on the outside of the left punch 4 and right punch 5, and they are fixed by pressing inward.

[0019] The working principle of this utility model is as follows: During assembly, the left punch 4 and right punch 5 are first fixedly installed at the bottom of the left and right sides of the upper die base 2 by fastening bolts 12. Then, the upper die base 2 and the lower die base 1 are slidably assembled. After the assembly is completed, the upper die base 2 and the lower die base 1 are installed in the stamping machine.

[0020] After assembly, plate 13 is placed on top of lower mold base 1 and driven to move from left to right. During the interval of plate 13 movement, upper mold base 2 is driven to move downward. During the downward movement of upper mold base 2, the left punch 4 on the left side of upper mold base 2 cooperates with lower mold base 1 to punch grooves on the left side of plate 13.

[0021] When the plate 13 area with the grooved part moves to the lower part of the right punch 5, the plate 13 with the grooved part can be punched out downward by the downward movement of the upper die base 2. By extending downward to the rivet head 6 on the lower side of the right punch 5, the punched plate 13 can be deformed and quickly stacked and riveted to complete the production of the stator and rotor.

[0022] It should be noted that during the process of driving the upper die base 2 to move downward for stamping, the design of the inclined plate 9 allows the inclined plate 9 to stretch the spring 11 to both sides. Under the action of the spring 11, the bottom roller 10 rolls to both sides on the upper surface of the sheet metal 13 and presses the sheet metal 13 downward. Therefore, when the sheet metal 13 is stamped by the left punch 4 and the right punch 5 on the left and right sides, the sheet metal 13 can better adhere to the upper surface of the lower die base 1, thereby ensuring the quality of stamping.

[0023] When stamping plates 13 of different thicknesses, first loosen the fastening bolts 12 on the outside of the right punch 5, and then use a wrench and an internal hexagon block 71 to drive the threaded rod 7 to rotate at the top of the upper die base 2. During the rotation of the threaded rod 7, the right punch 5 can be adjusted up and down by using the threaded connection between the threaded rod 7 and the top of the right punch 5, thereby adjusting the length of the rivet head 6 extending downward from the bottom of the right punch 5. This allows for quick-locking stacking and riveting assembly after stamping plates 13 of different thicknesses without having to replace the entire punch, thus improving stamping efficiency.

[0024] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
