[0002] Spokes are one of the most important parts of a bicycle, and the quality of spokes directly affects the performance of the entire bicycle. Spoke threading machines are one of the most important equipment for producing spokes. In the current process of producing spokes, the spoke blanks need to be threaded and then cut off at the ends, and some spokes will also be embossed with marks or patterns on the surface.
[0003] In the prior art, for example, Chinese patent number: CN218611484U discloses a bicycle spoke cutting and threading device, which includes: a workbench, a lower cutter seat is provided at the end of the workbench, and the lower cutter seat has a U-shaped groove extending to the left side of the workbench, and the U-shaped groove is used to place the spoke; a strip-shaped through hole provided on the workbench and vertically passing through the U-shaped groove; a lower tooth plate embedded and installed on the workbench and located at the rear side of the lower cutter seat; a sliding seat installed on the side of the workbench through a guide rail bracket, and the sliding seat has an upper tooth plate corresponding to the lower tooth plate; an upper cutter seat installed on the side of the workbench, the upper cutter seat corresponds to the lower cutter seat, and is raised and lowered by a driving assembly; and a rear baffle provided on the workbench and located at the rear side of the lower tooth plate. The utility model places the spoke on the lower tooth plate, cooperates with the upper tooth plate of the sliding seat to complete the thread rolling, and then the lower cutter seat cooperates with the upper cutter seat to complete the cutting and shaping of the spoke end, thereby realizing the spoke processing, and the strip-shaped through hole goes down to the embossing pliers, which can complete the embossing of the surface pattern mark, thereby improving the production efficiency.
[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that although it can place the spoke on the lower tooth plate, cooperate with the upper tooth plate of the sliding seat to complete the thread rolling, and then use the lower knife seat to cooperate with the upper knife seat to complete the cutting and shaping of the spoke end to realize the spoke processing, the single lower knife seat cooperates with the upper knife seat to cut the spoke, and can only produce a single spoke. When the spokes need to be produced in large quantities, the production efficiency is low, resulting in low production benefits of the enterprise. In addition, in the process of thread rolling, the spokes are prone to produce more silk scraps, and the silk scraps may adhere to the surface of the spoke under the action of magnetism, resulting in poor quality of spoke production. Utility Model Content
[0005] The purpose of the utility model is to solve the problem in the prior art that although the spokes can be placed on a lower tooth plate, the upper tooth plate of the sliding seat is cooperated to complete the thread rolling, and then the lower knife seat cooperates with the upper knife seat to complete the cutting and shaping of the spoke ends to achieve spoke processing, the single cutting of the spoke by the lower knife seat and the upper knife seat can only produce a single spoke. When the spokes need to be produced in large quantities, the production efficiency is low, resulting in low production benefits for the enterprise, and the spokes are prone to produce more wire scraps during the thread rolling process. The wire scraps may adhere to the surface of the spoke under the action of magnetism, resulting in poor quality of the spoke production.
