The invention discloses a manufacturing method of a wheel spoke . The method includes the following steps that S1, profile selection is performed, specifically, a plate-shaped profile with a variablecross section matched with the outer contour surface of a spoke finished product in shape is selected or prepared; S2, edge rolling is performed, specifically, the plate-shaped profile obtained in S1is sheared according to the size of the spoke, a profile with the suitable length is obtained, then edge rolling, opening aligning and butt-joint seam welding are performed, and a spoke rough blank isobtained; S3, shape modification is performed, specifically, the spoke rough blank obtained in S2 is shaped and machined, and a spoke fine blank is obtained; and S4, machining is performed, specifically, the spoke fine blank obtained in S3 is subjected to machining including assembling hole machining, center hole machining, end surface machining and outer diameter machining, and the spoke is manufactured. The invention also provides the wheel prepared with the method. According to the method, the material utilization rate can be effectively increased, the production efficiency can be greatlyimproved, the prepared spoke is high in strength, and weld joints are not prone to cracking.
本发明公开了一种车轮轮辐制造方法,包括以下步骤:S1、型材选型:选用或制备带有与轮辐成品外轮廓面形状相适配的变截面的板状型材;S2、卷圆:将步骤S1获得的板状型材依据轮辐大小剪切,得到长度适用的型材,而后卷圆、对口,对接缝焊接,制得轮辐粗坯;S3、修形:对步骤S2获得的轮辐粗坯进行整形加工,制得轮辐精坯;S4、机加工:对步骤S3获得的轮辐精坯进行包括装配孔、中心孔、端面和外径的机加工,制得轮辐。本发明还保护上述方法制备的车轮。本发明能够有效提高材料利用率,并能极大地提高生产效率,制备的轮辐强度高,焊缝不易开裂。
