Description

Technical Field

[0001] This utility model relates to the technical field of motor stator production equipment, specifically a multi-station continuous motor stator stamping device. Background Technology

[0002] As the core component of a motor, the stator's core is typically formed by stamping and laminating silicon steel sheets. The precision and production efficiency of stator laminations directly affect the motor's performance and manufacturing cost. With the surge in demand for motors from fields such as new energy vehicles and industrial automation, the production scale and quality requirements for stator laminations are continuously increasing, and traditional stamping equipment can no longer meet the demands for efficient and high-precision production.

[0003] In existing motor stator stamping processes, traditional equipment generally employs a decentralized process design, requiring the stamping and blanking of stator laminations to be completed separately on different equipment or at independent workstations. Due to this decentralized process, workpieces must be manually or mechanically transferred between different equipment or workstations. This process involves significant non-productive time, including time-consuming steps such as workpiece positioning and adjustment, and waiting for transfers. This results in extended production cycles for single laminations and low overall production efficiency, failing to meet the demands of modern manufacturing for efficient mass production. Therefore, there is an urgent need for a continuous stamping device that can integrate processes and reduce transfer time. Utility Model Content

[0004] The purpose of this invention is to provide a multi-station continuous motor stator stamping device to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A multi-station continuous motor stator stamping device includes an outer casing with a stamping cavity. A stamping table is installed inside the stamping cavity, and a stamping head is provided within the cavity. A stamping die is bolted to the bottom surface of the stamping head. A rotating shaft is rotatably connected to the wall of the stamping cavity, and a swing arm is mounted on the side of the rotating shaft. A material collection tray is connected to the bottom end of the swing arm. The outer casing has a first cavity inside, and driving components are provided within the first cavity and on the side of the outer casing. The driving components drive the stamping head to perform reciprocating vertical motion and cause the stamping die to press against the top surface of the stamping table. The driving components also drive the rotating shaft to... The reciprocating rotational motion rotates the material collection tray to a position below the raised stamping head. The stamping cavity provided by the outer casing offers a stable installation space for each component. The stamping table serves as the stamping support base and works in conjunction with the stamping die, which is bolted to the bottom of the stamping head, to ensure precise positioning during the stamping process. The drive unit connects the stamping head and the rotating shaft, enabling the stamping and material collection actions to be linked. The connection between the swing arm, the rotating shaft, and the material collection tray allows the material collection tray to rotate precisely to the designated position. This multi-component collaborative design reduces the gap between processes, shortens the production cycle of a single stamped piece, and thus improves overall production efficiency.

[0006] Furthermore, the driving component includes a connecting shaft installed in the first cavity, a turntable coaxially connected to the outer side of the connecting shaft, a connecting rod fixedly installed on the side of the turntable, a connecting rod rotatably connected to the free end of the connecting rod via a pin, the free end of the connecting rod being connected to the top surface of the stamping head via a pin, an opening being formed on the top surface of the stamping cavity, the connecting rod moving within the opening, a vertical limiting groove being formed on the side of the stamping cavity, a limiting block being installed on the side of the stamping head, the limiting block sliding within the limiting groove, and the driving component further includes a power component. The power component drives the connecting shaft to rotate. The first cavity provides installation space for components such as the connecting shaft and the turntable. The connecting shaft and the turntable are coaxially connected to ensure the synchronization of the rotational motion. The connecting rod and the connecting rod are rotatably connected by a pin. The connecting rod is then connected to the stamping head, realizing a smooth conversion from rotational motion to vertical reciprocating motion. The limiting groove on the side of the stamping cavity cooperates with the limiting block on the side of the stamping head to restrict the direction of movement of the stamping head, preventing the stamping head from deviating during movement. This ensures the precise docking of the stamping die and the stamping table, thereby improving the stamping accuracy of the stator laminations.

[0007] Furthermore, the outer casing has a second cavity communicating with the limiting groove and the first cavity. One end of the rotating shaft is located in the second cavity. The driving component includes a geared disc located in the second cavity. The geared disc and the rotating shaft are coaxially connected. A fixing rod is connected to the side of the limiting block. A vertical rack is installed at the free end of the fixing rod. The rack and the geared disc mesh. The second cavity provides a closed installation and movement space for the geared disc, rack, and other components, preventing impurities from interfering with the transmission process. The connection between the limiting block, the fixing rod, and the rack transmits the vertical movement of the punch head to the rack. The rack meshes with the geared disc, and the geared disc is then coaxially connected to the rotating shaft, realizing the linkage between the movement of the punch head and the rotational movement of the rotating shaft. No additional independent drive structure is required, simplifying the overall structure of the device, reducing energy consumption, and ensuring the synchronous coordination of the punching action and the material collection action, thereby improving the smoothness of the process connection.

[0008] Furthermore, the power component includes a motor mounted on the outside of the outer casing. The output end of the motor is connected to a drive gear, and a driven gear is coaxially connected to the outside of the connecting shaft. The drive gear and the driven gear mesh, and the radius of the drive gear is smaller than that of the driven gear. The motor, as a power source, transmits power to the connecting shaft through the meshing of the drive gear and the driven gear. The design of the drive gear having a smaller radius than the driven gear achieves the effect of speed reduction and torque increase, allowing the connecting shaft to obtain a more stable torque output. This, in turn, makes the movement of the stamping head driven by the turntable and connecting rod smoother, avoiding stamping accuracy deviations caused by unstable power output during the stamping process, thereby improving the stamping quality.

[0009] Furthermore, a protective cover is installed on the outside of the outer casing, covering the motor. The protective cover has a heat dissipation filter. The cooperation between the protective cover and the outer casing can isolate the motor from the external environment, preventing damage to the motor from external debris, dust, etc., and preventing personnel from accidentally touching the motor's operating parts and causing safety hazards. The heat dissipation filter on the protective cover can protect the motor while ensuring the heat dissipation requirements of the motor during operation, maintaining the motor's stable operating temperature, extending the motor's service life, and thus ensuring the continuous and stable operation of the entire device.

[0010] Furthermore, telescopic dust covers are installed on both sides of the limiting block, and the free ends of the telescopic dust covers are respectively connected to both sides of the limiting groove. The telescopic dust covers and the limiting groove are of the same width. The cooperation between the telescopic dust covers on both sides of the limiting block and the limiting groove can isolate the internal space of the limiting groove from the outside, preventing impurities such as iron filings and dust generated during the stamping process from entering the limiting groove. This avoids impurities affecting the smooth sliding of the limiting block in the limiting groove, ensuring the limiting effect of the limiting block on the stamping head, thereby maintaining the precise docking of the stamping die and the stamping table, and ensuring stamping accuracy.

[0011] Furthermore, the collecting tray is inclined when it is below the stamping head. The connection and cooperation between the collecting tray and the swing arm make it inclined when it is below the stamping head. This inclined structure utilizes gravity to allow the stamped workpiece to slide automatically to the lower end of the collecting tray, which facilitates the centralized collection of workpieces, reduces the time for manual workpiece sorting, and further improves production efficiency. At the same time, it avoids the problem of subsequent acceptance obstruction caused by the accumulation of workpieces in the collecting tray.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the multi-station continuous motor stator stamping device integrates the stamping and material collection processes through the linkage design of the drive components, stamping head, and rotating shaft, reduces the transfer links between processes, eliminates non-production time for transfer waiting, thereby shortening the production cycle of a single stamping piece, improving the overall production efficiency, and meeting the needs of modern manufacturing industry for efficient and high-precision mass production of motor stator stamping pieces.

[0015] 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.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a multi-station continuous motor stator stamping device, including an outer casing 1, the outer casing 1 having a stamping cavity 6, a stamping table 2 installed inside the stamping cavity 6, a stamping head 3 provided inside the stamping cavity 6, a stamping die 7 bolted to the bottom surface of the stamping head 3, a rotating shaft 9 rotatably connected to the wall of the stamping cavity 6, a swing arm 8 installed on the side of the rotating shaft 9, a material collection tray 4 connected to the bottom end of the swing arm 8, a first cavity 10 inside the outer casing 1, a driving component provided inside the first cavity 10 and on the side of the outer casing 1, the driving component driving the stamping head 3 to perform reciprocating vertical motion and causing the stamping die 7 to press the top surface of the stamping table 2, the driving component also driving the rotating shaft 9 to perform reciprocating rotational motion and causing the material collection tray 4 to press the top surface of the stamping table 2. When the disc 4 rotates to a position below the raised stamping head 3, the drive unit is activated. The drive unit generates two driving actions simultaneously. On one hand, it drives the stamping head 3 to reciprocate vertically. When the stamping head 3 moves downward, it drives the stamping die 7 on the bottom surface to move downward synchronously, so that the stamping die 7 squeezes the sheet metal on the top surface of the stamping table 2 to complete the stamping process. On the other hand, the drive unit drives the rotating shaft 9 to reciprocate. The rotation of the rotating shaft 9 will drive the swing arm 8 on the side to swing. The swing arm 8 will then drive the material collection disc 4 at the bottom to move. When the stamping head 3 rises after completing the stamping, the material collection disc 4 will rotate to a position below the raised stamping head 3 under the drive of the swing arm 8, so that the formed stator sheet stuck in the stamping die 7 falls into the material collection disc 4.

[0017] Specifically, the unloading roller for loading the roll material is placed on one side of the device, and the take-up roller is placed on the other side of the device. The free end of the roll material is passed through the stamping cavity 6 and finally fixed on the take-up roller. At the same time, the roll material is placed on the stamping table 2. During stamping, the take-up roller rolls up the roll material residue and pulls the roll material under the stamping die 7, thereby completing the loading.

[0018] As an embodiment of this utility model, the driving component further includes a connecting shaft 11 installed in the first cavity 10. A turntable 12 is coaxially connected to the outer side of the connecting shaft 11. A connecting rod 13 is fixedly installed on the side of the turntable 12. The free end of the connecting rod 13 is rotatably connected to a connecting rod 14 via a pin. The free end of the connecting rod 14 is connected to the top surface of the stamping head 3 via a pin. An opening is provided on the top surface of the stamping cavity 6, and the connecting rod 14 moves within the opening. A vertical limiting groove 21 is provided on the side of the stamping cavity 6. A limiting block is installed on the side of the stamping head 3, and the limiting block slides within the limiting groove 21. The driving component also includes a power component, which drives the stamping head 3. The connecting shaft 11 rotates, first driven by a power component. The rotation of the connecting shaft 11 will cause the turntable 12, which is coaxially connected to the outside, to rotate synchronously. When the turntable 12 rotates, it will cause the connecting rod 13, which is fixedly installed on the side, to make a circular motion. The free end of the connecting rod 13 pulls or pushes the connecting rod 14 through a pin. The connecting rod 14 moves in the opening on the top surface of the stamping cavity 6, thereby causing the stamping head 3 connected to it to make a vertical reciprocating motion. At the same time, the limiting block on the side of the stamping head 3 will slide synchronously in the vertical limiting groove 21 on the side of the stamping cavity 6, restricting the movement trajectory of the stamping head 3 and ensuring that the stamping head 3 always moves in the vertical direction.

[0019] As an embodiment of this utility model, the outer casing 1 further includes a second cavity 17 communicating with the limiting groove 21 and the first cavity 10. One end of the rotating shaft 9 is located in the second cavity 17. The driving component includes a gear disk 18 located in the second cavity 17. The gear disk 18 and the rotating shaft 9 are coaxially connected. A fixing rod 20 is connected to the side of the limiting block. A vertical rack 19 is installed at the free end of the fixing rod 20. The rack 19 meshes with the gear disk 18. When the punch head 3 moves vertically... During the reciprocating motion, the side limit block will slide within the limit groove 21. The sliding of the limit block will drive the rack 19 to perform vertical reciprocating motion via the side fixing rod 20. Since the rack 19 meshes with the gear disc 18 in the second cavity 17, the vertical motion of the rack 19 will be converted into the rotational motion of the gear disc 18. Since the gear disc 18 and the rotating shaft 9 are coaxially connected, the rotation of the gear disc 18 will drive the rotating shaft 9 to rotate synchronously, thereby realizing the linkage motion between the stamping head 3 and the rotating shaft 9.

[0020] As an embodiment of this utility model, the power component further includes a motor installed on the outside of the outer casing 1. The output end of the motor is connected to a drive gear 16, and the outer side of the connecting shaft 11 is coaxially connected to a driven gear 15. The drive gear 16 and the driven gear 15 mesh, and the radius of the drive gear 16 is smaller than the radius of the driven gear 15. The motor on the outside of the outer casing 1 is started first. After the motor runs, its output end will drive the drive gear 16 to rotate. Since the drive gear 16 and the driven gear 15 on the outside of the connecting shaft 11 mesh, and the radius of the drive gear 16 is smaller than that of the driven gear 15, the rotation of the drive gear 16 will drive the driven gear 15 to perform a decelerated rotational motion. The driven gear 15 is coaxially connected to the connecting shaft 11, thereby driving the connecting shaft 11 to rotate at a stable speed and torque, providing power support for the subsequent movement of the stamping head 3.

[0021] As an embodiment of this utility model, a protective cover 5 is further installed on the outside of the outer casing 1, covering the motor. The protective cover 5 has a heat dissipation filter. After the motor is installed on the outside of the outer casing 1, the protective cover 5 is installed on the outside of the motor and covers the motor, forming a closed protective space to prevent external debris from entering the motor. When the motor generates heat during operation, the heat will accumulate inside the protective cover 5. At this time, the heat dissipation filter on the protective cover 5 will form an air circulation channel. External cold air enters the protective cover 5 through the filter, exchanges heat with the surface of the motor, takes away the heat, and then discharges the hot air to achieve heat dissipation of the motor.

[0022] As an embodiment of this utility model, telescopic dust covers are further installed on both sides of the limiting block, and the free ends of the telescopic dust covers are respectively connected to both sides of the limiting groove 21. The telescopic dust covers and the limiting groove 21 are of the same width. When the stamping head 3 drives the limiting block to slide up and down in the limiting groove 21, the telescopic dust covers on both sides of the limiting block will expand and contract accordingly. When the limiting block slides upward, the lower telescopic dust cover contracts and the upper telescopic dust cover extends; when the limiting block slides downward, the upper telescopic dust cover contracts and the lower telescopic dust cover extends, always keeping the opening of the limiting groove 21 blocked and preventing impurities from entering the interior of the limiting groove 21.

[0023] As an embodiment of this utility model, the collecting plate 4 is tilted when it is below the stamping head 3. When the swing arm 8 drives the collecting plate 4 to rotate to below the stamping head 3, the collecting plate 4 will be tilted due to the installation angle design of the swing arm 8. The stamped workpiece falls off the stamping die 7 and into the tilted collecting plate 4. Under the action of gravity, the workpiece will slide along the tilted surface of the collecting plate 4 to the lower end of the collecting plate 4, realizing the automatic collection of the workpiece.

[0024] Specifically, driven by the driving component, the stamping head 3 moves vertically downwards, causing the stamping die 7, which is connected to the bottom surface by bolts, to move downwards synchronously. This causes the stamping die 7 to apply stamping pressure to the silicon steel coil on the top surface of the stamping table 2, thereby completing the forming process of the stator lamination. During this stage, the workpiece is tightly fitted into the cavity or working surface of the stamping die 7 due to the pressure of the stamping die 7. After the stamping is completed, the driving component continues to drive the stamping head 3 to move upwards to reset. The stamping die 7 rises synchronously with the stamping head 3. At this time, the stamping pressure of the stamping die 7 on the workpiece completely disappears, and the workpiece loses the pressure constraint that previously maintained the fitted state. At the same time, the workpiece itself has a certain weight, and under the action of gravity, it will gradually detach from the cavity or working surface of the stamping die 7, thus falling onto the collecting tray 4.

[0025] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
