Description

Technical Field

[0001] This utility model relates to the field of stamping machine platform structure technology, and in particular to a stamping machine platform servo rotary device. Background Technology

[0002] As the core components of a motor, the quality of the stator and rotor laminations directly affects the motor's energy efficiency and operational stability. Traditional stator and rotor stamping production uses a progressive die continuous blanking process, where silicon steel sheets are blanked into ring-shaped laminations and then stacked to form the final product.

[0003] In actual production, the rotor core is mainly formed by stacking several rotor laminations. Due to the difference in thickness in different areas of the rotor laminations during production, once all the rotor laminations are stacked, the error in the same area will accumulate and add up, resulting in poor uniformity of the rotor core, which ultimately affects the performance of the rotor core.

[0004] There is a need for a new type of servo rotary device for stamping presses that can solve the problems mentioned above. Utility Model Content

[0005] This utility model provides a servo rotary device for a stamping machine. By technically modifying the existing stator and rotor stamping machine, it solves the problem that the rotor core will have thickness errors during the processing of the stator and rotor of the existing stamping machine, resulting in poor product quality and precision.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A servo rotary device for a stamping press is installed at the stamping die of the stamping press. The stamping die includes an upper die and a lower die. The servo rotary device is provided at the lower die. The servo rotary device includes a rotary bushing and a drive motor. The rotary bushing is rotatably connected to the lower die. A stacking cavity is provided inside the rotary bushing for storing stacked layers of stator or rotor laminations. A drive motor is installed on the stamping press and is drivenly connected to the rotary bushing.

[0008] Preferably, the rotary bushing is rotatably connected to the lower mold via a fixed support bearing.

[0009] Preferably, the drive motor is a servo motor, and the output end of the servo motor is connected to the rotary bushing via a coupling. The stamping machine is also equipped with a servo motor encoder, which is used to control the rotation angle of the rotary bushing driven by the servo motor.

[0010] Preferably, the drive motor is mounted on a motor mounting bracket via an adjusting support, and the motor mounting bracket is fixedly connected to the stamping machine table via a punch press connecting plate.

[0011] Preferably, the adjusting support includes a horizontal adjusting screw and a vertical adjusting screw. The horizontal adjusting screw is used to adjust the installation position of the drive motor in the horizontal direction of the motor mounting bracket, and the vertical adjusting screw is used to adjust the installation position of the drive motor in the vertical direction of the motor mounting bracket.

[0012] Preferably, a matching positioning pin and positioning groove are provided between the upper mold and the lower mold.

[0013] Preferably, anti-tamper plates are symmetrically arranged on both sides of the motor mounting bracket. The anti-tamper plates are L-shaped steel plates, with their vertical edges attached to the drive motor housing via elastic damping pads, and their horizontal edges fixed to the motor mounting bracket via fixing bolts.

[0014] The beneficial effects of this utility model are as follows:

[0015] The present invention also provides a servo rotation device at the lower die of the stamping die of the stamping press. The servo rotation device includes a rotation bushing and a drive motor. The drive motor can drive the rotation bushing to rotate, causing the stamping pieces to rotate at a certain angle before being stacked and riveted. This ensures the perpendicularity, parallelism, and concentricity of the iron core, so that the thickness of the stacked stamping pieces with uneven thickness is evenly distributed, which can eliminate the problem of inconsistent product thickness and compensate for the stacking accumulation error caused by uneven material thickness, thereby improving the motor performance.

[0016] The drive servo encoder configured in this application controls the drive servo to perform high-precision indexing rotation, eliminating cumulative angle errors. Furthermore, when the servo rotary device used in this application produces the motor rotor, the servo rotary device rotates at a set angle, and the resulting superposition of these angles forms a motor rotor with a torsional shape. The rotor laminations are rotated and superimposed layer by layer to form a preset torque angle, thereby eliminating the influence of the rotor magnetic poles and improving motor performance.

[0022] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

The stacking cavity 211 is used to store the stacked layers of stator or rotor laminations. A drive motor 22 is installed on the stamping machine 1. The drive motor 22 is drivenly connected to the rotary bushing 21.

[0024] Furthermore, the rotary bushing 21 is rotatably connected to the lower mold via a fixed support bearing, which can improve the smoothness of rotation.

[0025] Furthermore, the drive motor 22 is a servo motor, and the output end of the servo motor is connected to the rotary sleeve 21 via a coupling. The stamping machine base 1 is also equipped with a servo motor encoder, which is used to control the rotation angle of the rotary sleeve 21 driven by the servo motor.

[0026] Furthermore, the drive motor 22 is mounted on the motor mounting bracket 4 via the adjusting support 3, and the motor mounting bracket 4 is fixedly connected to the stamping machine base 1 via the punching machine connecting plate.

[0027] Furthermore, the adjusting support 3 includes a horizontal adjusting screw 31 and a vertical adjusting screw 32. The vertical adjusting screw 32 is used to adjust the installation position of the drive motor 22 in the vertical direction of the motor mounting bracket 4. The horizontal adjusting screw 31 is connected to the motor mounting plate 5, and the drive motor is mounted on the motor mounting plate. The horizontal adjusting screw 31 is used to adjust the installation position of the drive motor 22 and the motor mounting plate 5 in the horizontal direction of the motor mounting bracket 4.

[0028] Furthermore, a matching positioning pin and positioning groove are provided between the upper and lower dies. The positioning pin and positioning groove can improve the stamping accuracy and stability, ensure that the silicon steel sheets can be quickly and accurately aligned when stacked, and reduce stamping deformation caused by inaccurate stacking.

The anti-tamper plates 6 are L-shaped steel plates, and their vertical edges are fitted to the housing of the drive motor 22 through elastic damping pads.

The servo rotary device 2 includes a rotary bushing 21 and a drive motor 22. The drive motor 22 can drive the rotary bushing 21 to rotate, causing the stamping pieces to rotate at a certain angle before being stacked and riveted. This ensures the perpendicularity, parallelism, and concentricity of the iron core, so that the thickness of the stacked stamping pieces with uneven thickness is evenly distributed, which can eliminate the problem of inconsistent product thickness and compensate for the stacking accumulation error caused by uneven material thickness. This improves the magnetic performance characteristics of the motor and improves the motor performance.

[0032] The drive servo encoder provided in this application controls the drive servo to perform high-precision indexing rotation, eliminating cumulative angle errors. Furthermore, when the servo rotary device 2 used in this application produces the motor rotor, the servo rotary device 2 rotates at a set angle and then superimposes the rotations to form a motor rotor with a twisted shape. The rotor laminations are rotated and superimposed layer by layer to form a preset torque angle, thereby eliminating the influence of the rotor magnetic poles and improving motor performance.
