[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A carbon fiber wheel rim preforming fixture includes a base 1, with casters 2 fixedly installed around the bottom of the base 1, and vertical poles 3 fixedly installed at both ends of the top of the base 1. A preforming device 4, an opening and closing separation device 5, and a forming and pressing device 6 are respectively arranged between the two vertical poles 3.

[0022] To facilitate the removal of the pre-formed carbon fiber wheel rim, an opening and closing separation device 5 is provided, including a fixed shaft 51 and a rotating sleeve 52. One end of the fixed shaft 51 is fixedly installed on the opposite surface of the vertical pole 3, and the rotating sleeve 52 is fixedly installed on the surface of the other vertical pole 3. An adjusting screw 53 is threadedly connected to the inner wall of the rotating sleeve 52. One end of the adjusting screw 53 passes through and extends to one end of the vertical pole 3, and an operating handwheel 54 is also fixedly installed on one end of the adjusting screw 53.

[0023] Specifically, this is implemented to facilitate the removal of the pre-formed carbon fiber wheel rim. The opening and closing separation device 5 includes a fixed shaft 51 and a rotating sleeve 52. One end of the fixed shaft 51 is fixedly installed on the opposite surface of the vertical pole 3, and the rotating sleeve 52 is fixedly installed on the surface of the other vertical pole 3. An adjusting screw 53 is threadedly connected to the inner wall of the rotating sleeve 52. One end of the adjusting screw 53 passes through and extends to one end of the vertical pole 3, and an operating handwheel 54 is also fixedly installed on one end of the adjusting screw 53. The opening and closing separation device 5 has a relatively simple structure, is easy to maintain and replace worn parts, thereby reducing long-term maintenance costs.

[0024] To achieve the pre-forming action of carbon fiber wheel rims, a pre-forming device 4 is provided, including a limiting forming plate 41 and a power forming plate 42. One end of the limiting forming plate 41 is rotatably connected to one end of the fixed shaft 51 through a bearing, and one end of the power forming plate 42 is rotatably connected to one end of the adjusting screw 53 through a bearing. Wheel rim forming grooves 43 are provided on the arc surface of the limiting forming plate 41 and the arc surface of the power forming plate 42.

[0025] Specifically, the wheel rim forming groove 43 opened on the arc surface of the limiting forming plate 41 and the power forming plate 42 can accurately guide the carbon fiber material to be formed according to the predetermined shape and size, ensuring the dimensional accuracy of the wheel rim; the design of the pre-forming device 4 plays an important role in ensuring the forming quality of carbon fiber wheel rims, improving production efficiency, reducing operation difficulty and maintenance costs, and is an indispensable part of the carbon fiber wheel rim production process.

[0026] Both the surface of the limiting forming plate 41 and the surface of the power forming plate 42 are provided with weight reduction holes 44. The surface of the limiting forming plate 41 is also provided with a ring array of insertion posts 45. The surface of the power forming plate 42 is provided with insertion holes 46. The inner wall of the insertion hole 46 is slidably inserted into the arc surface of the insertion post 45.

[0027] Specifically, the design of the weight-reducing hole 44 reduces the weight of the forming plate itself, making operation easier and reducing the overall weight of the equipment, making it easier to handle and move; the design of the insertion post 45 and the insertion hole 46 allows for precise alignment between the two forming plates, ensuring accurate alignment of the forming groove, thereby guaranteeing the precision of the wheel rim forming.

[0028] In order to realize the pressing action in the carbon fiber wheel rim forming, the forming pressing device 6 is set up, including a horizontal bar 61 fixedly installed at the top of the vertical pole 3, an infrared sensor 62 fixedly installed at the bottom of the horizontal bar 61, a drive plate 63 fixedly installed on one side surface of the horizontal bar 61, and a telescopic cylinder 64 fixedly installed on the surface of the drive plate 63.

[0029] Specifically, the use of infrared sensor 62 enables precise alignment of carbon fiber sheets in the manufacturing of carbon fiber wheel rims, allowing them to be individually bonded inside the wheel rim forming groove 43 to pre-form the wheel rim.

[0030] A U-shaped seat 65 is fixedly installed at the telescopic bottom end of the telescopic cylinder 64. The inner walls on both sides of the U-shaped seat 65 are rotatably connected to the pressing shaft 66 through bearings. A pressing wheel 67 is fixedly installed on the arc surface of the pressing shaft 66. The pressing wheel 67 is located directly above the wheel rim forming groove 43.

[0031] Specifically, this is implemented by adjusting the telescopic cylinder 64 to move the pressing roller 67 vertically. In the carbon fiber sheet application, the pressing roller 67 controls the carbon fiber sheet to adhere firmly without edge separation. During the layering process, the vertical position is adjusted by telescopic adjustment to form a prefabricated wheel rim through multi-layer pressing, thus providing the quality and precision of the prefabrication.

[0032] By integrating the preforming device 4, the opening and closing separation device 5, and the forming and pressing device 6, the preforming of carbon fiber wheel rims can be automated or semi-automated, reducing manual operation steps and improving production efficiency. The preforming device 4 can ensure that the carbon fiber material maintains uniform tension during the preforming process, thereby ensuring the dimensional accuracy and strength of the finished wheel rim. This improves production efficiency, ensures product quality, reduces labor intensity, and enhances safety.

[0033] Working principle: During operation, after the limiting forming plate 41 and the power forming plate 42 are pressed and bonded together, the operator takes carbon fiber sheets and bonds and stacks them inside the wheel rim forming groove 43 to preform them. During operation, the infrared lines of the infrared sensor 62 are aligned and the bonding operation is carried out. At the same time, the pressing roller 67 is used to press. Under the circumferential motion of the rotating limiting forming plate 41, the carbon fiber sheets rotate and bond inside the wheel rim forming groove 43 to form a ring. They are stacked one by one to gradually form a preformed wheel rim. After preformation, the operating handwheel 54 is used to rotate and drive the power forming plate 42 to separate from the limiting forming plate 41. The preformed wheel rim is taken out and placed into the forming mold to form a carbon fiber wheel rim.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
