Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a wheel hub spinning machine. Background Art

[0002] A wheel hub is a cylindrical metal component mounted on an axle, supporting the tire's inner profile. It's also called a rim, steel wheel, wheel, or wheel bell. Wheels come in a variety of types, depending on their diameter, width, forming method, and material. Aluminum alloy wheel spin forming is a process developed based on conventional spin forming for cylindrical parts. The resulting product boasts comparable precision to machining, while offering superior material utilization and mechanical properties.

[0003] During the hub spinning process of the hub spinning machine, the hub needs to be pressed by the upper and lower spindles to prevent the hub from shifting during the spinning process. After the hub spinning is completed, the material needs to be removed. For common spinning machines, the removal structure has certain inconveniences in use. Utility Model Content

Since the output end of the main drive motor 4 is connected to the spinning lower support plate 3, the spinning lower support plate 3 can be driven to rotate by the main drive motor 4, and then the entire spinning lower support plate 3 and the top pressure plate 6 drag the wheel hub to rotate, thereby performing the spinning action.

[0028] The annular gasket groove 12 is opened on the upper part of the inner support plate 5. The annular gasket groove 12 is located on the inner side of the upper part of the spun lower support plate 3, and the annular gasket groove 12 is annular, and a stripping ring 8 with an annular structure is overlapped in the groove of the annular gasket groove 12. The height of the stripping ring 8 is less than the groove depth of the annular gasket groove 12. Therefore, after the stripping ring 8 is placed in the groove of the annular gasket groove 12, it does not affect the normal lifting of the wheel hub by the surface of the spun lower support plate 3. At the same time, the top of the stripping ring 8 will be in contact with a part of the structure of the wheel hub, which is convenient for the subsequent lifting of the stripping ring 8 to lift the wheel hub. The bottom annular array of the stripping ring 8 is fixed with a stripping connector 9 extending downward and inward, and a groove is provided on the surface of the inner support plate 5 to allow the stripping connector 9 to extend into, that is, when the stripping ring 8 is attached to the groove of the annular gasket groove 12, the stripping connector 9 is placed in the groove of the inner support plate 5, and the stripping ring 8 moves longitudinally, and the stripping connector 9 will move longitudinally in the groove of the inner support plate 5, and anti-stripping grooves 10 are provided on the side walls of the groove of the inner support plate 5, and anti-stripping sliders 11 are fixed at both ends of the stripping connector 9. When the stripping connector 9 is placed in the groove of the inner support plate 5, the anti-stripping sliders 11 are inserted into the two groups of anti-stripping grooves 10, and the anti-stripping sliders 11 can slide in the grooves of the anti-stripping grooves 10, and when the top of the anti-stripping grooves 10 is closed, a limit is provided for the rise of the anti-stripping sliders 11.

[0029] The top pressure connector 7 is fixed to the lower part of the top pressure plate 6. The top pressure connector 7 adopts a rectangular structure. The inner side of the inner support plate 5 is combined into a rectangular groove adapted to the top pressure connector 7. Positioning connection holes 13 are opened on the surfaces of the stripping connector 9 and the top pressure connector 7. After the top pressure plate 6 is completely attached to the upper part of the wheel hub, the positioning connection holes 13 at the top pressure connector 7 and the stripping connector 9 are aligned. A group of connecting rods 14 can be horizontally inserted into the holes of the top pressure connector 7 and the stripping connector 9. A groove is set on the surface of the spun lower support plate 3, and the connecting rod 14 is horizontally arranged in the groove of the spun lower support plate 3. Under the connection of the connecting rod 14, the stripping ring 8 and the top pressure connector 7 are combined. When the hydraulic drive moves the top pressure plate 6 upward, the stripping ring 8 will move upward under the connection of the stripping connector 9, and the top of the stripping ring 8 lifts the wheel hub, thereby lifting the wheel hub upward.

[0030] The driving mechanism is arranged at the top of the spinning plate main board 1. The connecting rod parts 14 and the driving mechanism are distributed in multiple groups along the upper annular array of the spinning plate main board 1. The driving mechanism can make the multiple groups of connecting rod parts 14 move radially synchronously and extend into the groove of the positioning connection hole 13. The driving mechanism includes a rotating ring part 15, a guide inner plate 16, a guide sleeve 17, a guide slot 18 and a guide connection block 20. The rotating ring part 15 is rotatably installed on the top of the spinning plate main board 1. The guide sleeve 17 is fixed on the top of the rotating ring part 15. The guide inner plate 16 is slidably connected to the inner side of the guide sleeve 17. The guide slot 18 is provided on the surface of the guide inner plate 16. The guide slot 18 is slidably connected in the groove of the guide slot 18. One end of the connecting rod part 14 is connected to the guide connection block 20 by a pin. Through the connection of the pin, there is a certain rotational connection effect between the front end of the connecting rod part 14 and the guide connection block 20. The spinning A radial limit piece 19 is fixed to the top of the main board 1, and a groove is provided on the surface of the radial limit piece 19 to allow the connecting rod part 14 to pass through. The radial limit piece 19 can limit the connecting rod part 14 so that the connecting rod part 14 can move radially. At the same time, the larger space inside the connecting rod part 14 allows the connecting rod part 14 to move longitudinally to a certain extent. A part of the guide connecting block 20 is embedded in the guide groove 18 and cannot be detached. At the same time, the guide connecting block 20 can slide in the groove of the guide groove 18, and the connecting rod part 14 moves longitudinally, which can synchronously drive the guide inner plate 16 to move longitudinally on the inner side of the guide sleeve 17. The motor drive is set at the bottom of the rotating ring part 15, so that the rotating ring part 15 can rotate on the top of the spinning plate main board 1. After the rotating ring part 15 rotates, the guide connecting block 20 will change the contact point with the guide slot 18, thereby causing the connecting rod part 14 to move radially, so that the connecting rod part 14 enters the slot of the spinning lower support plate 3 and continues inward, and finally the connecting rod part 14 is inserted into the groove of the positioning connection hole 13, completing the combination of the stripping ring 8 and the top pressing connector 7. Conversely, after the rotating ring part 15 is rotated in the opposite direction, the connecting rod part 14 is pulled outward without affecting the normal rotation of the spinning lower support plate 3.
