The invention discloses a high-strength spoke manufacturing process, and relates to the technical field of spoke manufacturing. The high-strength spoke manufacturing process comprises the following steps that step 1, carbon steel is selected as a raw material for spoke manufacturing, and metallographic detection is adopted to analyze alloy components in the raw material and the three-dimensional spatial morphology of alloy structures. According to the high-strength spoke manufacturing process, during use, a spoke is manufactured in a hot forging mode, chromium and carbon are added in the manufacturing process to improve the strength of the spoke, in addition, acid pickling, phosphorization and saponification are adopted to pretreat the spoke before the spoke is drawn and formed, the plasticity of the spoke in the drawing process can be further improved, so that the phenomenon that cracks occur on a spoke upset head and an elbow is reduced; and meanwhile, under the action of an anti-corrosion coating, the spoke can be prevented from rusting, and the storage time of the formed spoke is prolonged.
本发明公开了一种高强度辐条制作工艺,涉及辐条制作技术领域,该高强度辐条制作工艺,包括以下步骤:步骤一、选用碳素钢作为辐条制作的原料,采用金相检测对原料中合金成分、合金组织的三维空间形貌进行分析,本发明中,使用时,通过热锻的方式制作辐条,在制作过程中,加入铬和碳,以提高辐条的强度,此外,在辐条拉拔成形前,采用酸洗、磷化、皂化对辐条进行预处理,可进一步提高辐条的拔拉时的可塑性,以降低辐条镦头和弯头出现裂纹的现象,同时配合防腐涂层的作用下,还可避免辐条生锈,延长辐条成形后的存放时间。
