Description

Technical Field

[0001] This utility model relates to the field of motor rotor forming technology, specifically to a motor rotor lamination processing and forming device. Background Technology

[0002] Rotor laminations are made by stamping silicon steel sheets into laminations of different specifications to suit the stator and rotor of motors with different power ratings. The rotating part of the motor rotor is made of stacked silicon steel sheets. There are short-circuit rings at both ends of the rotor, which is the mechanism for the motor's power output. The motor stator, the fixed part inside the motor, is made of stacked silicon steel sheets and has embedded coil windings. The windings generate a rotating magnetic field, which drives the rotor to rotate.

[0003] Currently, when manufacturing motors, the internal rotor laminations need to be stamped by stamping equipment on silicon steel sheets before the finished product can be obtained. However, in most existing stamping processes, workers place the round silicon steel sheets on the stamping table and then stamp them. When placing the silicon steel sheets, workers need to manually adjust the precise position of the silicon steel sheets to avoid inaccurate stamping. This results in a long stamping time, affecting the manufacturing efficiency and failing to meet current needs.

[0004] Therefore, a motor rotor lamination processing and forming device that can improve manufacturing efficiency is now being designed to address this type of defect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a motor rotor lamination processing and forming device, which solves the problem of slow processing efficiency of motor rotor laminations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motor rotor lamination processing and forming device, comprising a processing box, wherein side sliding frames are fixedly connected to both sides of the inner cavity of the processing box via fixing plates, a load-bearing pressure platform is slidably installed between the inner sides of the two side sliding frames, a docking slot is provided on the right side of the load-bearing pressure platform, and a lower mold seat is slidably installed on the inner side of the docking slot, and a cylinder is fixedly connected to the top of the processing box via an opening, and a lower pressure seat is fixedly connected to the bottom end of the cylinder.

[0007] Preferably, the bottom of the lower pressure seat is fixedly connected to a stamping die that cooperates with the lower die seat via a fixing plate, and the top of the lower die seat is fixedly connected to a limiting ring frame that cooperates with the stamping die.

[0008] Preferably, telescopic spring rods are fixedly connected to both sides of the rear of the load-bearing pressure table via fixing plates, and the rear end of the telescopic spring rods penetrates through the processing box and extends to the rear of the processing box. A pressure-bearing horizontal plate is fixedly connected between the two sections of the telescopic spring rods extending to the rear of the processing box, and a spring is sleeved on the surface of the telescopic spring rods and between the inner wall of the load-bearing pressure table and the processing box.

[0009] Preferably, the processing box has a rearward sliding slot, and the rear of the lower pressure seat is fixedly connected to an inclined pressure frame that cooperates with the pressure-bearing horizontal plate, and the inclined pressure frame passes through the rearward sliding slot and extends to the rear of the processing box.

[0010] Preferably, the bottom of the inner cavity of the processing box is provided with an inclined guide groove, and the right side of the bottom of the load-bearing pressure table is fixedly connected with a vertical scraper that works in conjunction with the inclined guide groove by a fixing block. Beneficial effects

[0011] This invention provides a device for processing and forming motor rotor laminations. Compared with existing technologies, it has the following advantages:

[0012] (1) The motor rotor lamination processing and forming device has a lower mold seat installed by opening a docking slot on the right side of the load-bearing pressure table, and a limiting ring frame installed on the top of the lower mold seat. It is used in conjunction with the pressure plate and the inclined pressure frame. The setting of these structures allows the operator to accurately place the rotor lamination inside the limiting ring frame. After the inclined pressure frame squeezes the pressure plate, it drives the limiting ring frame to move directly below the stamping die. The whole process is simple and quick, and the operator does not need to make tedious position adjustments, which effectively improves the overall preparation efficiency.

[0013] (2) The motor rotor lamination processing and forming device is equipped with a sloping guide groove at the bottom of the processing box and a vertical scraper. The structure allows the stamping die to rise after stamping, and the load-bearing pressure table to move forward and reset, so that the stamping fragments can be swept away by the vertical scraper at the bottom and discharged through the sloping guide groove, which is convenient for the staff to clean and collect, and meets the current use requirements.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a motor rotor lamination processing and forming device, including a processing box 1. Side sliding frames 2 are fixedly connected to both sides of the inner cavity of the processing box 1 via fixing plates. A load-bearing pressure platform 3 is slidably installed between the inner sides of the two side sliding frames 2. A docking slot 4 is provided on the right side of the load-bearing pressure platform 3, and a lower mold seat 5 is slidably installed on the inner side of the docking slot 4. The lower mold seat 5 and the docking slot 4 are interference-fitted and have friction. A cylinder 6 is fixedly connected to the top of the processing box 1 through an opening. A lower pressure seat 7 is fixedly connected to the bottom end of the cylinder 6. The bottom of 7 is fixedly connected to a stamping die 8 that works with the lower die base 5 via a fixing plate. The top of the lower die base 5 is fixedly connected to a limiting ring frame 9 that works with the stamping die 8. Both sides of the rear of the load-bearing pressure table 3 are fixedly connected to telescopic spring rods 11 via fixing plates. The rear end of the telescopic spring rods 11 passes through the processing box 1 and extends to the rear of the processing box 1. A pressure-bearing horizontal plate 12 is fixedly connected between the two telescopic spring rods 11 extending to the rear of the processing box 1. A spring 14 is sleeved on the surface of the telescopic spring rods 11 and between the inner wall of the load-bearing pressure table 3 and the processing box 1.

[0022] In use, the operator first inserts the corresponding lower mold seat 5 into the inner side of the docking slot 4. Then, the operator places the rotor lamination to be stamped into the inner side of the limiting ring frame 9. Subsequently, the cylinder 6 is activated to push the lower pressure seat 7 and the stamping mold 8 down. When the lower pressure seat 7 descends, it will drive the inclined pressure frame 13 to descend synchronously. When the inclined pressure frame 13 descends, it will press down on the bearing plate 12. After the bearing plate 12 is pressed, it will use the limiting of the two telescopic spring rods 11 to pull the load-bearing pressure table 3 backward under the guidance of the side sliding frame 2. When the inclined pressure frame 13 pulls the load-bearing pressure table 3 to the last part, the limiting ring frame 9 and the rotor lamination are located directly below the stamping mold 8. At this time, after the lower pressure seat 7 has completely descended, the stamping mold 8 at the bottom will stamp the rotor lamination inside the limiting ring frame 9.

[0023] Furthermore, a rearward sliding slot 10 is provided at the rear of the processing box 1, and a sloping pressure frame 13 that cooperates with the pressure-bearing horizontal plate 12 is fixedly connected to the rear of the lower pressure seat 7 via a bracket. The sloping pressure frame 13 is pre-set so that the limiting ring frame 9 can be moved directly below the stamping die 8 before the stamping die 8 is stamped. The sloping pressure frame 13 passes through the rearward sliding slot 10 and extends to the rear of the processing box 1. A sloping guide groove 15 is provided at the bottom of the inner cavity of the processing box 1, and a vertical scraper 16 that cooperates with the sloping guide groove 15 is fixedly connected to the right side of the bottom of the load-bearing pressure table 3 via a fixing block.

[0024] After processing is completed, the cylinder 6 is started to drive the lower pressure seat 7 and the stamping die 8 to rise until the inclined pressure frame 13 is completely separated from the pressure plate 12. Then, the load-bearing pressure table 3 moves forward and resets under the elastic force of the spring 14. At this time, the vertical scraper 16 at the bottom pushes the stamped metal fragments forward to discharge them. Then, the workers take out the stamped rotor laminations and replace them.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
