Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of spoke production, in particular to a high-strength spoke production process. Background technique [0002] Spokes are many rods, rods or straight lines extending outward on the same plane from a center or hub. Spokes are usually drawn and formed when they are processed; [0003] The manufacturing process of high-strength spokes currently on the market still has defects during use. For example, the produced spokes have low strength, are prone to bending and breaking, and the produced spokes are easily corroded and difficult to store for a long time. Contents of the invention [0004] The purpose of the present invention is to provide a high-strength spoke manufacturing process to solve the problems raised in the above-mentioned background technology. [0005] The technical scheme that the present invention adopts is as follows: [0006] A high-strength spoke manufacturing process, comprising the follow...
