Hinge shaft part and machining method thereof
The invention discloses a hinge shaft part and a machining method thereof.The hinge shaft part comprises a cylindrical rod part which comprises an insertion part, a spline and a rotating part, the insertion part is used for being inserted into a first connecting piece in a hinge mechanism, and the rotating part is used for being rotationally connected with the first connecting piece in the hinge mechanism; the spline is used for being connected with a second connecting piece in the hinge mechanism in a nested mode. The flange is connected with the end part of the rod part, and the flange and the rod part are of an integrated structure; the inner hole penetrates from the flange to the rod part, and the inner hole is a square blind hole; wherein the rod part, the flange and the inner hole are coaxially arranged. The hinge shaft part is provided with the spline and the flange so that the hinge shaft part can be connected with an external part, and the functional requirement that the hinge shaft part in an automobile door structure needs to be linked with other parts is met; in order to produce the hinge shaft part, the machining method takes a cold extrusion process as a main process, the production efficiency of the part is improved, and the machining method is more suitable for batch production. The invention relates to the technical field of automobile manufacturing.
本申请公开了一种铰链轴零件及其加工方法，铰链轴零件包括杆部，其呈圆柱状，包括插入部、花键和转动部，其中插入部用于插入铰链机构中的第一连接件，转动部用于与铰链机构中的第一连接件转动连接，花键用于与铰链机构中的第二连接件嵌套连接；法兰，其与杆部的端部相接且与杆部为一体式结构；内孔，其从法兰贯穿至杆部，内孔为方形盲孔；其中，杆部、法兰以及内孔均同轴设置。本申请中的铰链轴零件设置有花键和法兰以用于与外部零件相接，满足汽车门结构中铰链轴零件需要与其他零件进行联动的功能性需求；为了生产上述铰链轴零件，本加工方法将冷挤压工艺作为主要工艺，提升该零件的生产效率，更适合批量生产。本申请涉及汽车制造技术领域。
