[0024] The present application will be further described in detail below in combination with the drawings and specific embodiments:

[0025] Referring to Figures 1-5A wheel hub processing device includes a lower mold unit 1, an upper mold unit 2 and a clamping assembly 3.

[0026] The lower mold unit 1 includes a work station 11 and a lower mold 12, wherein the lower mold 12 is installed on the work station 11, and has a portion on the lower mold 12 for placing or accommodating the aluminum rod, which can be located at the center of the lower mold 12. The aluminum rod can be installed to the lower mold from the side of the lower mold, or a longitudinal through hole can be opened in the center of the lower mold so that the aluminum rod can be lifted from the center of the lower mold by a lifting component to be exposed above the lower mold.

[0027] A first bracket 31 is installed on the workbench 11 . The first bracket 31 can be specifically installed on one side of the workbench 11 . One or two extension bars extend from the first bracket 31 , and a first driving unit 32 is installed on the extension bar.

[0028] First guide rails 33 are longitudinally installed at the left and right ends of the first bracket 31, and a second bracket 34 is slidably connected to the first guide rails 33. Specifically, the left and right ends of the second bracket 34 respectively have corresponding sliders 35, so that the second bracket 34 can slide longitudinally on the first bracket 31 through the cooperation between the sliders 35 and the first guide rails 33.

[0029] Furthermore, the output end of the first drive unit 32 is connected to the end of the second bracket 34. For example, if a first drive unit 32 is provided at the left and right ends of the first bracket 31, the output ends of the two first drive units 32 are connected to the left and right ends of the second bracket 34, respectively. Thus, the two first drive units 32 drive the longitudinal movement of the second bracket 34. Providing a first drive unit 32 at both ends can make the longitudinal movement of the second bracket 34 more stable. In this embodiment, the first drive unit 32 can be a pneumatic cylinder, a hydraulic rod, or an electric cylinder.

[0030] Furthermore, a second guide rail 36 is mounted on the second bracket 34 and can be arranged transversely on the upper surface of the second bracket 34. Two first sliders 37 are slidably connected to the second guide rail 36. Each first slider 37 is fixedly provided with an extension arm 38, and each extension arm 38 is fixedly provided with a clamping block 39. In this embodiment, the first slider 37, the extension arm 38, and the clamping block 39 constitute a clamping unit.

[0031] Specifically, two clamping units are slidably connected to the second guide rail 36, each corresponding to a second drive unit 310. The two second drive units 310 are respectively fixed to the second bracket 34 or the workstation 11, and their output ends are connected to the corresponding clamping units to control their lateral movement. In one embodiment, the output end of the second drive unit 310 is connected to the downwardly extending portion of the inner end of the extension arm 38. The second drive unit 310 can be a pneumatic cylinder, hydraulic rod, or electric cylinder.

[0032] Thus, the first bracket 31, the first drive unit 32, the first guide rail 33, the second bracket 34, the second guide rail 36, and the clamping unit constitute a clamping assembly, and the two second drive units 310 act synchronously to clamp the aluminum rod through the two clamping blocks 39 and release the aluminum rod when necessary.

[0033] As one embodiment, a notch 391 adapted to the raw material (aluminum rod) is formed at the outer end of the clamping block 39 .

[0034] The upper mold unit 2 includes a frame 21 , a mounting block 22 , a third driving unit 23 , a first upper mold 24 and a second upper mold 25 , wherein the frame 21 is mounted on a driving component for driving the upper mold to close the mold.

[0035] Mounting block 22 is slidably connected to frame 21. The output end of third drive unit 23 is connected to mounting block 22, driving the lateral movement of mounting block 22. A first upper mold 24 and a second upper mold 25 are both mounted on mounting block 22. Driven by third drive unit 23, the desired mold is moved to a position above lower mold 12. Third drive unit 23 can be a pneumatic cylinder, hydraulic rod, or electric cylinder.

[0036] In this embodiment, the first upper die 24 is used for the first step, namely, preforming the blank; the second upper die 25 is used for the second step, namely, forming the hub ribs. In practice, the first upper die 24 is first moved above the lower die 12, and then the upper die unit is driven by the drive component to close the mold, completing the first step of preforming the blank. The second upper die 25 is then moved above the lower die 12 by the third drive unit 23, and the upper die unit is then driven by the drive component to close the mold, completing the second step of forming the hub ribs.

[0037] Furthermore, the first upper mold 24 and the second upper mold 25 are arranged on the left and right sides and their centers are located on the same straight line.

[0038] As another embodiment, the first upper mold 24 and the second upper mold 25 can also be switched by a robotic arm.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
