Description

Technical Field

[0001] The utility model relates to the field of rotor sheet stamping dies, in particular to a multi-station rotor sheet stamping die. Background Art

[0002] Rotor sheets are key components in motors or generators. They are made through complex stamping and forming processes, with specific shapes and structures designed to optimize the performance and efficiency of the motor. As one of the core components of the motor, rotor sheets play a crucial role in modern motor technology. During the production and processing of rotor sheets, stamping dies are usually required to produce the rotor sheets needed in equipment such as motors and generators.

[0003] In traditional rotor sheet stamping dies, the die base is the basic structure of the entire die, responsible for supporting and fixing each component of the entire die. It is usually made of strong metal materials to ensure the stability and reliability of the die. The blanking unit is located at the top of the die and is used for the preliminary blanking operation of the rotor sheet. Each station is equipped with blanking tools, which can cut according to the set shape and size of the rotor sheet. Modern multi-station rotor sheet stamping dies usually integrate an automated control system to manage the operation process of the die. These systems can automatically adjust the working sequence between stations and monitor the parameters of the blanking and forming processes.

[0004] However, the die base in traditional rotor sheet stamping dies often does not have a stable fixing structure. Usually, the rotor sheet is directly processed on the workbench surface. This stamping fixing method may cause the offset of the rotor sheet, resulting in inaccurate stamping positions of the rotor sheet and affecting the stamping quality of the rotor sheet. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a multi-station rotor sheet stamping die, aiming to improve the problem that the die base in traditional rotor sheet stamping dies often does not have a stable fixing structure, resulting in inaccurate stamping positions of the rotor sheet and affecting the stamping quality of the rotor sheet.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A multi-station rotor sheet stamping die, including a base, wherein a plurality of first chutes are opened inside the base, a motor is fixedly connected inside the base, the output end of the motor is fixedly connected with a turntable, a plurality of arc-shaped rods are rotatably connected to the upper surface of the turntable, a plurality of sliding tables are arranged inside the base, the sliding tables are slidably connected inside the first chutes, one end of the arc-shaped rod is rotatably connected to the side wall of the sliding table, a clamping plate is fixedly connected to the top of each sliding table, a stamping table is arranged on the top of the base, a plurality of second chutes are opened inside the stamping table, the clamping plate is slidably connected inside the second chutes, and a supporting component is arranged at the bottom of the base, and the supporting component is used for the supporting structure.

[0007] Further, the support assembly includes a support table, and the support table is fixedly connected to the bottom of the base.

[0008] Further, a fixing frame is fixedly connected to the side wall of the support table, and a rotating table is fixedly connected to the top of the fixing frame.

[0009] Further, a hydraulic push rod is fixedly connected to the side wall of the fixing frame, and the output end of the hydraulic push rod is rotatably connected to a second rotating plate.

[0010] Further, a first rotating column is rotatably connected to the inside of the rotating table, and a first rotating plate is fixedly connected to the outer wall of the first rotating column.

[0011] Further, a second rotating column is rotatably connected to the inside of the first rotating plate, and the second rotating column is fixedly connected to the inside of the second rotating plate.

[0012] Further, a punching frame is rotatably connected to the outer wall of the second rotating column, and a connecting frame is fixedly connected to the side wall of the fixing frame.

[0013] Further, the punching frame is slidably connected to the inside of the connecting frame, and a punching tool is fixedly connected to the bottom of the punching frame.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, firstly, the motor outputs a rotating force to the turntable to drive the turntable to rotate. At this time, the multiple arc-shaped rods on the surface of the turntable also rotate and change the inclination angle. The movement of the multiple turntables can pull the sliding table.

[0016] 2. In the utility model, the hydraulic push rod outputs a pushing and pulling force to the second rotating plate on the side wall of the fixing frame to drive the second rotating plate to rotate and change the inclination angle, and finally push the punching frame to slide inside the punching tool. While the punching frame slides, the punching tool can cut the rotor sheet. With this structure, the cutting force of the punching tool can be adjusted according to the specifications of different rotor sheets, improving the applicability of this device and ensuring the accuracy and efficiency of the punching process.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: a multi-station rotor sheet stamping die, including a base 1, a plurality of first chutes 2 are provided inside the base 1, a motor 3 is fixedly connected inside the base 1, the output end of the motor 3 is fixedly connected with a turntable 4, a plurality of arc-shaped rods 5 are rotatably connected to the upper surface of the turntable 4, a plurality of slide tables 6 are arranged inside the base 1, the slide tables 6 are slidably connected inside the first chutes 2, one end of the arc-shaped rod 5 is rotatably connected to the side wall of the slide table 6, a clamping plate 7 is fixedly connected to the top of each slide table 6, a stamping table 8 is arranged on the top of the base 1, a plurality of second chutes 9 are provided inside the stamping table 8, the clamping plate 7 is slidably connected inside the second chutes 9, and a support assembly is arranged at the bottom of the base 1, and the support assembly is used for supporting the structure.

[0024] Specifically, first place the rotor sheet on the surface of the stamping table 8, then start the motor 3, the motor 3 outputs a rotational force to drive the turntable 4 to start rotating, and the plurality of arc-shaped rods 5 on the surface of the turntable 4 rotate and change the inclination angle accordingly. These movements guide the slide tables 6 to slide inside the first chutes 2, and the movement of the slide tables 6 causes the clamping plates 7 on their tops to move inside the second chutes 9, thereby effectively fixing the rotor sheet on the surface of the stamping table 8 and preventing it from shifting during the stamping process. This design not only ensures the stable fixation of the rotor sheet but also can adapt to rotor sheets of different specifications. This mechanism not only improves the accuracy of the stamping process but also significantly enhances the applicability of the equipment and the flexibility of operation.

[0025] Referring to Figure 3, the support assembly includes a support table 10, the support table 10 is fixedly connected to the bottom of the base 1, a fixed frame 11 is fixedly connected to the side wall of the support table 10, a turntable 13 is fixedly connected to the top of the fixed frame 11, a hydraulic push rod 12 is fixedly connected to the side wall of the fixed frame 11, the output end of the hydraulic push rod 12 is rotatably connected to a second rotating plate 16, a first rotating column 14 is rotatably connected inside the turntable 13, a first rotating plate 15 is fixedly connected to the outer wall of the first rotating column 14, a second rotating column 17 is rotatably connected inside the first rotating plate 15, the second rotating column 17 is fixedly connected inside the second rotating plate 16, a punching frame 18 is rotatably connected to the outer wall of the second rotating column 17, a connecting frame 19 is fixedly connected to the side wall of the fixed frame 11, the punching frame 18 is slidably connected inside the connecting frame 19, and a punching tool 20 is fixedly connected to the bottom of the punching frame 18.

[0026] Specifically, the hydraulic push rod 12 applies a pushing and pulling force to the second rotating plate 16 through the side wall of the fixed frame 11, pushing the second rotating plate 16 to rotate and change its inclination angle. The movement of the second rotating plate 16 simultaneously drives the first rotating plate 15 to rotate. The top first rotating column 14 of the first rotating plate 15 starts to rotate inside the turntable 13, and the angle change of the first rotating column 14 also drives the bottom second rotating column 17 to rotate. The bottom punching frame 18 of the second rotating column 17 slides inside the punching tool 20 accordingly. As the punching frame 18 slides, the punching tool 20 can accurately cut the fixed rotor sheets. This structural design allows adjusting the cutting force of the punching tool 20 according to the specifications of different rotor sheets, thereby improving the applicability and flexibility of the equipment. At the same time, this system ensures the accuracy and high efficiency of the punching process, ensuring that each rotor sheet can be accurately punched according to the expected shape and size.

[0027] Working principle: When it is necessary to fix the rotor sheet, first place it on the surface of the stamping table 8. At this time, start the motor 3. The motor 3 outputs a rotating force to the turntable 4 to drive the turntable 4 to rotate. At this time, the multiple arc-shaped rods 5 on the surface of the turntable 4 also rotate and change the inclination angle. The movement of the multiple turntables 4 can pull the sliding table 6 and drive the sliding table 6 to slide inside the first chute 2. Through the sliding of the sliding table 6, the clamping plate 7 on its top can slide inside the second chute 9 to effectively fix the rotor sheet on the surface of the stamping table 8 to prevent it from shifting during the stamping process, and it can adapt to rotor sheets of different specifications, ensuring the accuracy of the stamping process while improving the applicability. When it is necessary to perform stamping operations on the fixed rotor sheet, start the hydraulic push rod 12. The hydraulic push rod 12 outputs a pushing and pulling force on the side wall of the fixing frame 11 to drive the second rotating plate 16 to rotate and change the inclination angle. At this time, the second rotating plate 16 drives the first rotating plate 15 to rotate. While the first rotating plate 15 rotates, the first rotating column 14 on its top rotates inside the rotating table 13. Through the angle change of the first rotating column 14 and the first rotating plate 15, the second rotating column 17 at their bottom is driven to rotate. While the second rotating column 17 rotates, the blanking frame 18 at its bottom slides inside the blanking tool 20. While the blanking frame 18 slides, the rotor sheet can be cut by the blanking tool 20. With this structure, the cutting force of the blanking tool 20 can be adjusted according to the specifications of different rotor sheets, improving the applicability of this device and ensuring the accuracy and efficiency of the blanking process.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
