[0019] See also Figure 1-5 As shown, a steel wheel shaping device for manufacturing a single steel wheel roller includes a curved surface rolling block 1, an oil cylinder 2, an electromagnetic heating coil 3, a first rack block 5, a first gear 6, a second rack block 7, an arc-shaped gear rod 8, a second gear 9, a V-shaped frame 10, a fixed guide wheel 11, a reduction motor 12, a hydraulic lift 17 for lifting a steel wheel workpiece 15, and a side support 18 for tooling the steel wheel workpiece 15. The back of the curved surface rolling block 1 is fixedly connected to the output end of the oil cylinder 2 and is located on the curved surface rolling block. 1. A second rack block 7 connected to one end of the back side of the first rack block 5 is meshed with a first gear 6. A ceramic short column 4 is installed inside the ring block 510 at the top of the first rack block 5. The top end face of the ceramic short column 4 is fixedly connected to one end of the electromagnetic heating coil 3. The electromagnetic heating coil 3 and the curved rolling block 1 are dislocated and move to contact the steel wheel workpiece 15. The electromagnetic heating coil 3 is covered by a movable cover at the convex part to be shaped and repaired on the steel wheel workpiece 15. Combine Figure 3 and Figure 5 As shown, by connecting the robot arm connecting flange 14 to the end of the external robot arm, the external robot arm can be used to move the connected electromagnetic heating coil 3 and the curved surface rolling block 1 to the position inside or outside the steel wheel workpiece 15 to be shaped, and at the same time, the relative position of the contact is touched by using a workpiece with the same curvature to prevent secondary deformation during the rolling process; The curved surface rolling block 1 and the second rack block 7 are pushed and pulled forward and backward by the extension of the oil cylinder 2. At the same time, the second rack block 7 moving forward or backward drives the first gear 6 to rotate forward or reverse, so that the first rack block 5 meshing with the first gear 6 moves in the opposite direction to the second rack block 7, so as to complete the replacement between the electromagnetic heating coil 3 and the curved surface rolling block 1 at the part to be finalized; The electromagnetic heating coil 3 is used to heat the covered part at a high temperature, so that the convex part to be formed is quickly heated to a hot state, ensuring that the ductility of the convex part to be formed can be quickly implemented after it is heated. By removing the electromagnetic heating coil 3 and replacing it with the curved surface rolling block 1, the cylinder 2 is used to reciprocate and squeeze the convex part to be formed. In combination with the curvature of the curved surface rolling block 1 being consistent with the curvature of the steel wheel workpiece 15, the convex part to be formed is gradually pressurized. The benefit of this is that by utilizing the extension and contraction of the oil cylinder 2 as the power for the alternating movement of the electromagnetic heating coil 3 and the curved surface rolling block 1, the two shaping processing tools can be quickly replaced nearby, which greatly shortens the duration of the traditional processing tool replacement process, has high shaping processing efficiency, and has good quality of the shaped and trimmed curved surface. At the same time, the corresponding shape end of the electromagnetic heating coil 3 is utilized to cover the convex parts to be shaped, ensuring sufficient heating at each convex part, providing a hot and extensible processing surface for subsequent rolling, and reducing the difficulty of shaping processing.

[0020] The middle part of the side wall of the arc-shaped gear rod 8 is fixedly connected to the flange 210 located on the cylinder body of the oil cylinder 2 by a connecting bolt 211. The two fixed guide wheels 11 and the second gear 9 are distributed in a triangular shape to form a structure for positioning the arc-shaped gear rod 8. Each of the fixed guide wheels 11 is in rolling contact with the inside of the corresponding arc groove 810 located on the surface of the arc-shaped gear rod 8. The second gear 9 and the inner tooth surface of the arc-shaped gear rod 8 are meshed and connected to each other. The second gear 9 and the shaft end of the reduction motor 12 connected to the middle of the V-shaped frame 10 are connected to each other through a coupling. The arc-shaped gear rod 8 forms a rolling power for the curved rolling block 1 with the central axis of the steel wheel workpiece 15 as the center of the circle; Combine Figure 1 and Figure 2 As shown, the operation of the reduction motor 12 drives the connected second gear 9 to rotate back and forth, so that the arc-shaped gear rod 8 meshing with the second gear 9 and connected to it reciprocates within a range of 120 degrees. Since the arc-shaped gear rod 8 generates a rolling force on the curved surface rolling block 1 with the central axis of the steel wheel workpiece 15 as the center, the arc-shaped gear rod 8 and the curved surface rolling block 1 connected to it via the oil cylinder 2 perform reciprocating rolling on the convex part to be formed. The benefit of this is that: the arc-shaped toothed rod 8 which is concentric with the steel wheel workpiece 15 is in a reciprocating driven state, which greatly reduces the space occupied by the processing structure, and the curved surface rolling block 1 connected to the arc-shaped toothed rod 8 contacts the convex part to be formed, so that the curved surface rolling block 1 rolls the convex part to be formed, especially solving the problem of inconvenience in implementing rolling forming treatment due to limited internal space of the steel wheel.

[0021] Two driving rollers 16 are arranged in parallel at the top of the hydraulic lift 17, and the two driving rollers 16 are in rolling contact with the corresponding surfaces of the steel wheel workpiece 15. One side of each side support 18 is provided with an electromagnet combination curved surface 19, and the electromagnet combination curved surface 19 is magnetically attracted and fixed to the corresponding surface of the steel wheel workpiece 15 by an electromagnetic field. Combine Figure 1As shown, the same curved side surfaces of the two side supports 18 are in contact with the surface of the steel wheel workpiece 15, and at the same time, the electromagnet combined curved surface 19 that generates a magnetic field when energized is used to fix the steel wheel workpiece 15. After the magnetic fixation is released, the hydraulic lift 17 is operated to push the two driving rollers 16 upward, so that the steel wheel workpiece 15 is lifted and rotated sideways under the action of the running driving rollers 16, so as to achieve the effect of adjusting the processing position.

[0022] Furthermore, the first gear 6 is rotatably installed between the two side plates 610, one end of the side plate 610 is fixedly connected to the cylinder body of the oil cylinder 2, and a slide 521 is installed at the other end of the side plate 610, and the slide 521 is slidably connected to the first guide rail 520 located at the corresponding side wall of the first rack block 5.

[0023] Furthermore, the two ends of the V-shaped frame 10 are rotatably connected to the lateral shaft ends of the two fixed guide wheels 11, and the two side rods and the reduction motor 12 of the V-shaped frame 10 are fixedly connected to the corresponding parts on one side of the same rectangular block 13. A robotic arm connecting flange 14 is installed on the other side of the rectangular block 13, and the robotic arm connecting flange 14 is fixedly connected to the end of the external robotic arm.

[0024] Furthermore, the curvature of the curved rolling block 1 matches the curvature of the surface of the steel wheel workpiece 15, ensuring that the curvature remains consistent after shaping and repair.

[0025] Furthermore, the side brackets 18 are arranged in groups of two, and a second guide rail 20 is slidably mounted on the bottom of the two side brackets 18 .

[0026] Working principle: Combination Figure 3 and Figure 5 As shown, by connecting the robot arm connecting flange 14 to the end of the external robot arm, the external robot arm can be used to move the connected electromagnetic heating coil 3 and the curved surface rolling block 1 to the position inside or outside the steel wheel workpiece 15 to be shaped, and at the same time, the relative position of the contact is touched by using a workpiece with the same curvature to prevent secondary deformation during the rolling process; The curved surface rolling block 1 and the second rack block 7 are pushed and pulled forward and backward by the extension of the oil cylinder 2. At the same time, the second rack block 7 moving forward or backward drives the first gear 6 to rotate forward or reverse, so that the first rack block 5 meshing with the first gear 6 moves in the opposite direction to the second rack block 7, so as to complete the replacement between the electromagnetic heating coil 3 and the curved surface rolling block 1 at the part to be finalized; The electromagnetic heating coil 3 is used to heat the covered part at a high temperature, so that the convex part to be formed is quickly heated to a hot state, ensuring that the ductility of the convex part to be formed can be quickly implemented after it is heated. By removing the electromagnetic heating coil 3 and replacing it with the curved surface rolling block 1, the cylinder 2 is used to reciprocate and squeeze the convex part to be formed. In combination with the curvature of the curved surface rolling block 1 being consistent with the curvature of the steel wheel workpiece 15, the convex part to be formed is gradually pressurized. The advantages of this method are as follows: by utilizing the extension and contraction of the oil cylinder 2 as the power for the alternating movement of the electromagnetic heating coil 3 and the curved surface rolling block 1, the two shaping processing tools can be quickly replaced nearby, which greatly shortens the time of the traditional processing tool replacement process, has high shaping processing efficiency, and has good quality of the shaped and trimmed curved surface. At the same time, the corresponding shape end of the electromagnetic heating coil 3 is used to cover the convex parts to be shaped, ensuring sufficient heating of each convex part, providing a hot and ductile processing surface for subsequent rolling, and reducing the difficulty of shaping processing; Combine Figure 1 and Figure 2 As shown, the operation of the reduction motor 12 drives the connected second gear 9 to rotate back and forth, so that the arc-shaped gear rod 8 meshing with the second gear 9 and connected to it reciprocates within a range of 120 degrees. Since the arc-shaped gear rod 8 generates a rolling force on the curved surface rolling block 1 with the central axis of the steel wheel workpiece 15 as the center, the arc-shaped gear rod 8 and the curved surface rolling block 1 connected to it via the oil cylinder 2 perform reciprocating rolling on the convex part to be formed. The benefit of this is that: the arc-shaped toothed rod 8 which is concentric with the steel wheel workpiece 15 is in a reciprocating driven state, which greatly reduces the space occupied by the processing structure, and the curved surface rolling block 1 connected to the arc-shaped toothed rod 8 contacts the convex part to be formed, so that the curved surface rolling block 1 rolls the convex part to be formed, especially solving the problem of inconvenience in implementing rolling forming treatment due to limited internal space of the steel wheel.
