浅析吊扇叶片成形模具中凹、凸模成形面的车削加工方法

Analysis of a Ceiling Fan Blade Forming Concave, Convex Molding Surface Machining Method of Mould

吊扇叶片成形模是大型的方形模具,其型面加工一般采用铣削方式进行加工,但由于模具的长度尺寸大,所需的机床型号也大,多数生产厂家不具备这样的大型机床。而三维凸面铣削加工的精度也难以保证,即使能保证,加工成本也高。因此,设计了一套加工方案,使此套模具可以在普通车床上加工,而且有加工周期短、生产成本低、加工精度高等特点。

A ceiling fan blade forming mould is square mould large, its surface is usually machined by milling processing, but due to the large size of die, the required type of machineis also large, most manufacturers do not have such large machine tool. And it is difficult to guarantee the three-dimensional convex milling machining precision, even if can guarantee,processing cost is high. Therefore, a set of processing scheme is designed, so that this set of mould can be in ordinary lathe, and processing cycle short, the production cost is low,the processing precision high.
