The invention belongs to the technical field of telescopic supporting rods, and particularly relates to a cold extrusion forming method for a telescopic supporting rod and the telescopic supporting rod. A metal raw material is subjected to two-stage annealing and cold extrusion treatment after coating, and then a part is subjected to heat treatment reinforcement, so that the telescopic supporting rod which is formed through pure cold extrusion and high in strength is manufactured. The telescopic supporting rod component is simple in structure, high in fatigue resistance and light in weight, the product quality of the telescopic supporting rod component is effectively improved, various metal treatment modes are creatively integrated and arranged in the whole machining process, and the telescopic supporting rod component has remarkable substantive features.

    本发明属于伸缩支杆技术领域,具体涉及一种伸缩支杆冷挤压成型方法及伸缩支杆,通过对金属原材料进行两段的退火、皮膜后冷挤压处理,然后对部件进行热处理加固的方式,制作出纯冷挤压成型,抗疲劳强度高且重量较轻的伸缩支杆部件,有效提高了伸缩支杆部件产品质量,且整个加工过程创造性地整合和排列了多种金属处理方式,具有显著的实质性特点。
