Machining device and method for full metal hexagon flange face bolt

The invention belongs to the technical field of extrusion forming, and provides a machining device and method for a full metal hexagon flange face bolt. The rod end of a bolt blank to be machined is inserted into a positioning hole of a die core, axial force is applied to the small-diameter shaft end of the cone end of the bolt blank to enable the taper diameter external circle of the bolt blank to be forcedly squeezed into a hexagon hole in a hexagon flange face die, and therefore the purpose that a hexagon flange face is extruded on the cone end external circle of the bolt blank is achieved.The problem that the machining efficiency of milling the hexagon flange face after turning is low is solved, the production efficiency is improved, and the requirements for batch production are met. 本发明提供种全金属六角法兰面螺栓的加工装置及加工方法，将待加工的螺栓坯料的杆端插入模芯的定位孔内，在螺栓坯料的锥体端的小直径端轴向施力，使螺栓坯料的锥度直径外圆强行挤入六角法兰面模的六角孔内，进而达到在螺栓坯料的锥体端外圆挤出六角法兰面的目的。以解决车削后进行铣削六角法兰面加工效率低的问题，提高生产效率，满足批量生产的要求。属于挤压成型技术领域。
