It is also called a wheel rim, steel rim, wheel, and tire bell. There are many types of rims depending on the diameter, width, molding method, and material. There are three methods for manufacturing rims: gravity casting, forging, and low-pressure precision casting. These rims form rim blanks after molding, but the rims need to be refined and polished afterwards. The existing technology often uses a milling machine to refine the rims and a sandblasting machine to polish the rims.

The clockwork spring 64 is fixedly mounted on the winding wheel 63.

[0023] The feeding assembly 4 transfers the rim blank to the bottom of the processing box 1, the clamping assembly 7 descends to the bottom of the processing box 1 to clamp the rim blank on the feeding assembly 4 and drive the rim blank to rise into the processing box 1, then the layer plate assembly 6 located below the milling machine 2 is actuated, the driving wheel 62 rotates to drive the winding plate 61 to move, the support bar 611 moves in the moving groove, the winding plate 61 composed of the support bar 611 and the deformation bar 612 is located below the milling machine 2 to close the processing box 1, and the support bar 611 is located below the clamping assembly 7 to support the clamping assembly 7 and the rim blank, the winding plate 61 moves and is released from the winding wheel 63 and the spring spring 64 accumulates power, the milling machine 2 performs milling and finishing processing on the rim blank, and the debris in the processing process falls onto the winding plate 61 below the milling machine 2, and when the winding plate 61 is opened again, the driving wheel 62 drives the winding plate 61 to move, and the spring spring 64 drives the winding wheel 63 to rotate, and the winding plate 61 is opened again. The winding wheel 63 winds up the excess part of the winding plate 61. During the winding process of the winding plate 61, the debris on the winding plate 61 falls down. After the milling machine 2 completes the processing of the rim stock, the clamping assembly 7 drives the rim stock to continue to rise and move to the position of the sandblasting machine 3. The layer plate assembly 6 located below the sandblasting machine 3 is actuated, and the corresponding winding plate 61 moves to the bottom of the sandblasting machine 3. The winding plate 61 is located below the sandblasting machine 3 to close the processing box 1. The sandblasting machine 3 sprays out grinding sand to polish the surface of the rim stock, remove burrs on the surface of the rim stock and improve the smoothness. The grinding sand falls onto the winding plate 61 below. When the corresponding winding wheel 63 winds up the winding plate 61, the grinding sand on the corresponding winding plate 61 falls down. After the sandblasting machine 3 completes the processing of the rim stock, the clamping assembly 7 continues to drive the rim stock to rise to the position of the discharging assembly 5, and the discharging assembly 5 discharges the processed rim stock.

[0024] The rim blank is moved from the feeding component 4 to the positions of the milling machine 2, the sandblasting machine 3 and the discharging component 5 in sequence by the clamping component 7, so that the rim blank can be subjected to a combined processing of milling and sandblasting, the rim blank can be finely trimmed and polished, defects such as bumps and burrs on the rim blank can be removed, and the surface finish of the rim blank can be improved, thereby improving the quality of the rim blank. The rim blank can be subjected to feeding, milling, sandblasting and discharging in sequence, thus saving the transportation of the rim blank between different processing equipment and improving the processing efficiency. When the rim blank is subjected to milling and sandblasting, the winding plate 61 corresponding to the milling machine 2 and the sandblasting machine 3 closes the processing box 1, and the debris generated by the milling and the grinding sand sprayed by the sandblasting machine 3 fall onto the corresponding winding plate 61. After the processing is completed, the winding plate 61 is wound to release the sealing of the processing box 1, and the debris and grinding sand on the winding plate 61 fall down, which is convenient for collecting and reusing the debris and grinding sand, thereby improving the cleanliness of the processing box 1, and the debris and grinding sand will not accumulate in the processing box 1 to affect the processing.

[0026] The clamping assembly 7 descends to the position of the feeding assembly 4, clamps the rim blank on the feeding assembly 4, and then rises. The clamping assembly 7 drives the rim blank to rise and move through the feeding port to the position of the milling machine 2. When the milling machine 2 and the sandblasting machine 3 complete the processing of the rim blank, the closing plate 51 moves to open the discharge port, and the clamping assembly 7 drives the rim blank to rise. The rim blank passes through the discharge port, and the closing plate 51 moves to the bottom of the rim blank. The transfer conveyor belt 52 on the closing plate 51 moves to the bottom of the rim blank. The clamping assembly 7 moves downward to place the rim blank on the transfer conveyor belt 52 to release the clamping of the rim blank. The transfer conveyor belt 52 moves to drive the rim blank to move and discharge.

[0027] Example 3, reference Figure 1-Figure 11 , which is different from the above-mentioned embodiment, is that: the clamping assembly 7 includes a plurality of clamping units 71, a driving unit 72 and a lifting unit 73, the driving unit 72 includes a rotating ring 721, and the plurality of clamping units 71 are arranged on the rotating ring 721, the clamping unit 71 includes a pushing cylinder 711 and a clamping block 712, the pushing cylinder 711 is fixedly installed on the rotating ring 721, the output end of the pushing cylinder 711 passes through the rotating ring 721 and slidably cooperates with the rotating ring 721, the clamping block 712 is fixedly installed at the output end of the pushing cylinder 711, and a clamping groove is provided on the clamping block 712.

[0028] The pushing cylinder 711 drives the clamping block 712 to move, and the multiple clamping blocks 712 clamp the rim blank. The rotating ring 721 in the driving unit 72 rotates, and the rotating ring 721 drives the clamping block 712 to rotate. The clamping block 712 drives the rim blank to rotate, so that when the sandblasting machine 3 processes the rim blank, the rim blank can be driven to rotate, so that the rim blank is evenly sandblasted and polished, the polishing of the rim blank is more uniform, and the polishing effect is better.

[0029] Example 4, reference Figure 1-Figure 11 , which is different from the above-mentioned embodiment, is that the driving unit 72 also includes a driving ring gear 725, a driving gear 722, a driving motor 723 and a fixed frame 724, the rotating ring 721 is rotatably connected to the fixed frame 724, the driving ring gear 725 is fixedly mounted on the rotating ring 721, the driving motor 723 is fixedly mounted on the fixed frame 724, the driving gear 722 is fixedly mounted on the output end of the driving motor 723, and the driving gear 722 is meshed with the driving ring gear 725.

[0030] The driving motor 723 drives the driving gear 722 to rotate, the driving gear 722 drives the driving gear ring 725 to rotate, the driving gear ring 725 drives the rotating ring 721 to rotate, and the rotating ring 721 drives the clamped wheel rim blank to rotate.

[0031] Example 5, reference Figure 1-Figure 11 , which is different from the above-mentioned embodiment in that: the lifting unit 73 includes a plurality of telescopic cylinders 731, a support frame 732, a closing plate 733 and a closing spring 734, the support frame 732 is fixedly mounted on the top of the processing box 1, the telescopic cylinder 731 is fixedly mounted on the support frame 732, the output end of the telescopic cylinder 731 is fixedly mounted on the fixed frame 724, one end of the closing spring 734 is fixedly mounted on the support frame 732, and the other end of the closing spring 734 is fixedly mounted on the closing plate 733, and the closing plate 733 is located at the discharge port.

[0032] The telescopic cylinder 731 passes through the discharge port to drive the clamping unit 71 and the driving unit 72 to move, and drives the rim blank clamped on the clamping unit 71 to move. Because the telescopic cylinder 731 passes through the discharge port, the closing plate 51 cannot completely close the discharge port. The closing plate 733 is pressed into the discharge port by the closing spring 734. The closing plate 733 is sleeved on the output end of the telescopic cylinder 731. The closing plate 51 moves to the top of the closing plate 733. The closing plate 51 cooperates with the closing plate 733 to close the discharge port. The sealing prevents the debris and grinding sand in the processing box 1 from splashing to the outside of the processing box 1 through the discharge port, and will not pollute the external environment of the processing box 1. When the telescopic cylinder 731 drives the clamping assembly 7 and the rim blank clamped by it to move to the discharge assembly 5, the closing plate 51 moves to open the discharge port, and the fixed frame 724 rises to push the closing plate 733 to rise. The closing plate 733 compresses the closing spring 734, and the telescopic cylinder 731 drives the rim blank to move through the discharge port to the top of the processing box 1.

During the rotation of the driving wheel 62, the driving groove on the driving wheel 62 engages with the support bar 611, and the driving wheel 62 pushes the support bar 611 to move. Because the support bar 611 moves in the moving groove, the support bar 611 and the deformation bar 612 will not bend, thereby pushing the winding plate 61 to move. The driving wheel 62 pushes the winding plate 61 to move, and the support bar 611 and the deformation bar 612 located outside the moving groove lose the limitation of the moving groove, the deformation bar 612 can be deformed and bent, and the winding wheel 63 can wind the winding plate 61.

[0035] The support bar 611 is made of one of stainless steel and carbon steel, and the deformation bar 612 is made of one of rubber and silicone.
