Description

Technical Field

[0001] This utility model relates to the field of magnetic pole processing technology, and in particular to a magnetic pole rounded corner stamping forming device. Background Technology

[0002] In the manufacturing of electromagnetic equipment such as motors and generators, magnetic poles are core components, and their edge shape and surface finish directly affect the electromagnetic performance and operational stability of the equipment. To avoid problems such as tip discharge and stress concentration during magnetic pole assembly and use, the edges of the magnetic poles need to be rounded and the burrs generated on the surface after stamping need to be removed. Therefore, the rounding and burr removal of magnetic poles are key processes in the magnetic pole processing flow. Currently, the industry mostly uses separate equipment for rounding and deburring magnetic poles. That is, after rounding is completed by a special stamping machine, the magnetic poles are manually transferred to a grinding machine for surface treatment. Although some highly automated production lines use robotic arms for transfer, they still require two independent control systems to control the stamping and grinding equipment respectively. The existing processing method has obvious shortcomings: First, the split operation requires manual or mechanical transportation, and the process connection is cumbersome, resulting in low processing efficiency; second, manual transportation is prone to magnetic pole positioning deviation, affecting processing accuracy; third, the stamping die is in direct contact with the magnetic pole, which is prone to surface damage, and traditional grinding equipment is difficult to clean burrs completely, affecting product quality; fourth, the two sets of equipment are controlled independently, which increases equipment investment and maintenance costs. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a magnetic pole rounded corner stamping forming device, which more accurately solves the issues of single function, lack of comprehensiveness and safety, and inability to meet diverse needs.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a magnetic pole rounded corner stamping forming device, including an operating table, a stamping component and a grinding component. The stamping component and the grinding component are both installed above the operating table. A positioning component is provided on the surface of the operating table. The positioning component is connected to a control system. The control system can determine the position of the magnetic pole by controlling the positioning component.

[0005] Furthermore, the positioning component includes a groove formed on the surface of the operating table, a placement piece inside the groove, the outer diameter of the placement piece matching the groove, and electric push rods symmetrically fixedly installed at both ends of the groove. The control system divides the extension process of the extended end of the electric push rod into two segments.

[0006] Furthermore, an arc-shaped piece is fixedly connected to the top of the electric push rod by bolts, and the curvature of the arc-shaped piece perfectly matches the side curvature of the placement piece.

[0009] Furthermore, a flexible gasket is embedded in the inner wall of the mold cavity.

[0021] like Figures 1-4 As shown in the figure, this utility model proposes a magnetic pole rounding stamping forming device, which can realize the integrated processing of magnetic pole rounding stamping and surface burr removal, greatly improving the accuracy and efficiency of magnetic pole processing. Its overall structure mainly consists of three parts: an operating table 1, a stamping component 3, and a grinding component 4. The operating table 1 has a positioning component 2 on its surface, which can accurately fix the magnetic pole to be processed in a preset stamping position, providing a stable and reliable positioning guarantee for subsequent rounding stamping and burr removal, ensuring the accuracy of the operation process. After completing the rounding stamping of the magnetic pole, the device smoothly moves the magnetic pole to the position of the grinding component 4, thereby completing the deburring of the magnetic pole surface, achieving a seamless connection from stamping to grinding. The positioning component 2 includes a placement plate 201, which has a disc-shaped structure with a layer of highly elastic and frictional rubber sheet adhered to its surface. A cross-shaped opening is located at the center of the rubber sheet. This cross-shaped opening structure allows the rubber to effectively clamp magnetic poles of different sizes through its elastic deformation. After the magnetic pole to be processed is placed on the surface of the placement plate 201 through the cross-shaped opening of the rubber sheet, the rubber sheet fits tightly against the magnetic pole surface, effectively preventing the magnetic pole from shifting during processing. Simultaneously, a groove matching the outer diameter of the placement plate 201 is provided on the surface of the operating table 1 corresponding to the installation position of the placement plate 201. The placement plate 201 is placed directly inside this groove, and the sidewalls of the groove provide longitudinal restraint for the placement plate 201, thus initially determining its longitudinal position. To further improve positioning accuracy, electric push rods 202 are symmetrically fixed to both sides of the groove. An arc-shaped piece 203 is bolted to the top of each electric push rod 202, and the curvature of the arc-shaped piece 203 perfectly matches the side curvature of the placement plate 201. When the placement piece 201 is placed into the slot, the electric push rods 202 on both sides start synchronously and extend to the preset length. The arc-shaped plates 203 abut against the side walls of the placement piece 201 from both sides, and the lateral position of the placement piece 201 is determined by the balancing effect of the thrust from both sides. By combining the longitudinal limiting of the slot with the lateral positioning of the electric push rods 202, precise positioning of the placement piece 201 on the surface of the operating table 1 is achieved, thus ensuring the stamping position accuracy of the magnetic poles. The control system divides the extension process of the extended end of the electric push rod 202 into two segments. The two positions of the placement plate determined by the electric push rod 202 are the stamping point and the grinding point, respectively. The system internally uses an STM32F10x microcontroller with abundant GPIO resources and timer functions. It can precisely control the motor drive chip by outputting PWM waveforms, thereby controlling the electric push rod 202 and accurately determining the extension distance of the electric push rod 202.

[0022] After the positioning component 2 positions the magnetic pole to the stamping point, the stamping component 3 immediately starts working. The stamping component 3 includes a hydraulic rod 301, which is fixed above the operating table 1, with its output end directly facing the center of the placement piece 201. The output end of the hydraulic rod 301 is fixedly connected to a stamping die 302 via a flange. The cavity shape of the die 302 matches the required rounded corner size of the magnetic pole. To prevent the die 302 from scratching or indenting the surface of the magnetic pole during the stamping process, a flexible gasket 303 is embedded in the inner wall of the cavity of the die 302. The gasket 303 is made of polyurethane material and has good cushioning performance. After the positioning component 2 positions the magnetic pole to the stamping point, the hydraulic rod 301 pushes the die 302 downward according to the preset pressure and stroke parameters. After the die 302 contacts the magnetic pole, under the action of hydraulic driving force, the edge of the magnetic pole is stamped and modified into the preset rounded corner shape. After the stamping is completed, the hydraulic rod 301 drives the die 302 to reset, waiting for the next stamping command. After the stamping process is completed, the electric push rod 202 on one side of the positioning assembly 2 remains extended, while the electric push rod 202 on the other side retracts. The difference in thrust between the two electric push rods 202 pushes the placement piece 201, along with the magnetic pole, towards the grinding point. A servo motor 401 is fixedly mounted at the bottom of the grinding point via a motor 401 mount. The output end of the servo motor 401 is connected to a drive shaft via a coupling. A vacuum nozzle 402 is fixedly mounted at the top of the drive shaft, with its suction port facing the grinding point. When the placement piece 201 is located at the grinding point, the vacuum nozzle 402 is at the center of its bottom. When the placement piece 201 moves above the grinding point under the thrust, the vacuum nozzle 402 activates and generates negative pressure, firmly adsorbing and fixing the placement piece 201 at the grinding point. A hydraulic rod 403 is also fixed above the grinding point via a bracket. The output end of the hydraulic rod 403 is threaded to a grinding component 404. The grinding component 404 has a ring-shaped structure, with its inner diameter slightly larger than the outer diameter of the magnetic pole, and its inner wall is evenly covered with a layer of sandpaper. After the placement piece 201 is fixed by the vacuum nozzle 402, the hydraulic rod 403 extends downwards, moving the grinding component 404 downwards until it completely covers the magnetic pole. At this point, the servo motor 401 is activated, driving the drive shaft and vacuum nozzle 402 to rotate, thereby driving the placement piece 201 and the magnetic pole to rotate together. During the rotation of the magnetic pole, the sandpaper layer on the inner wall of the grinding component 404 fully contacts and rubs against the surface of the magnetic pole, effectively cleaning away the burrs generated by the stamping process. After grinding is complete, the hydraulic rod 403 resets the grinding component 404, the vacuum nozzle 402 stops working, and the processed magnetic pole can be removed.
