Abstract:

Cold extrusion technology was used to replace the machining process in order to improve the processing efficiency and strength of chain pipe. Through the comprehensive analysis of chain pipe part performance, a more perfect chain pipe cold extrusion process route, the corresponding chain pipe cold extrusion die structure and main die parts were designed. Through the test, the feasibility using the chain pipe cold extrusion process to replace lathing process technology was verified. The qualified cold extuding chain pipe parts were obtained using the technology.
