| description | A forged and pressed embedded step shaft comprises a head part, a rod part and a head part blank, the head part blank is a sleeve formed through forging, and an annular groove is formed in the contact position of the rod part and the head part blank. The head blank is sleeved with the annular groove of the rod part and then forged and pressed into the annular groove, the pressed material and the annular groove are tightly attached to form the head, and the rod part and the head blank are connected into a whole to form the embedded step shaft which is forged and pressed. According to the utility model, the machining allowance can be reduced or a step shaft forging process is omitted, the utilization rate of raw materials is improved, the manufacturing cost is reduced, the head part and the rod part can be manufactured by using different metal materials as required, and a new technology for manufacturing the step shaft by using combined materials is created; and the effect is more obvious when precious material |
