The embodiment of the invention provides a foaming steering wheel and a manufacturing method, the foaming steering wheel comprises a steering wheel framework, a foaming body and a functional pad, the foaming body is formed by placing the steering wheel framework in a foaming mold for foaming forming, comprises a hub part, a spoke part and a handle ring part, and comprises a primary foaming body and a secondary foaming body; the hub part and the spoke part are formed by the primary foaming body, a wrapping base face is formed on the handle ring part, the functional pad wraps the wrapping base face, the secondary foaming body is formed on the side, away from the wrapping base face, of the functional pad, and a circumferential closed contour of the handle ring part is formed or the secondary foaming body and the primary foaming body jointly form the circumferential closed contour of the handle ring part. According to the steering wheel, the hub part and the spoke part are formed through two-time foaming forming and one-time foaming, whether appearance defects which cannot be repaired exist in the appearance area of the hub part or not can be directly detected, waste of parts and production time can be reduced, part cost and production cost are saved, and production efficiency is improved.
本说明书实施例提供一种发泡方向盘及制作方法,发泡方向盘,包括方向盘骨架、发泡体和功能垫,发泡体由方向盘骨架置于发泡模具中进行发泡成型,包括轮毂部、轮辐部和把圈部,发泡体包括一次发泡体和二次发泡体,一次发泡体成型轮毂部和轮辐部,并在把圈部形成包覆基面,功能垫包覆在包覆基面,二次发泡体成型在功能垫远离包覆基面的一侧,形成把圈部的周向封闭轮廓或与一次发泡体共同形成把圈部的周向封闭轮廓。方向盘通过两次发泡成型,一次发泡形成轮毂部和轮辐部,可直接检测轮毂部外观区域内是否有无法返修的外观缺陷,可减少零件和生产工时的浪费,节约零件成本、生产成本和提高生产效率。
