Hot forging bolt machining method

The invention discloses a hot forging bolt machining method, and belongs to the technical field of machining. The hot forging bolt machining method includes the following steps that step 1, blanking is carried out to obtain a blank, and the two ends of the blank are subjected to end face flattening and chamfering turning to obtain a blank I; step 2, the blank I is subjected to rod shrining to obtain a blank II; step 3, the blank II is subjected to heat-forming to form a bolt head and a washer surface, and a blank III is obtained; and step 4, subsequent processing is carried out on the semi-finished bolt, and a finished bolt is obtained. The problems that in the prior art the washer surface machined by turning is prone to be oval, and turning is time-consuming and labor-intensive are solved. The production cost is saved, and the dimension consistency of the machined washer surface is better. 本发明公开了一种热锻螺栓加工方法，属于机械加工技术领域，该热锻螺栓加工方法包括以下步骤：步骤1，下料，得到毛坯，并其两端均平端面和车倒角处理，得到毛坯一；步骤2，对毛坯一进行缩杆加工，得到毛坯二；步骤3，对毛坯二热成型处理，形成螺栓头部和垫
