在毛主席革命路线指引下,我厂广大职工坚持自力更生精神,试制成功两台带式输送机托辊加工简易专用机床。经过几年生产实践,效果较好,既能提高生产效率和加工质量,又能减轻工人劳动强度。一、半自动切管机(图1) 用此机床可以一次完成下料与车3×30°倒角两道工序。适用于钢管直径φ76,φ89,φ Under the guidance of Chairman Mao’s revolutionary line, the vast majority of our factory workers insisted on the spirit of self-reliance and successfully trial-produced two simple and special machine tools for belt conveyor idler processing. After several years of production practice, the effect is better, both to improve production efficiency and processing quality, but also reduce the labor intensity of workers. First, semi-automatic pipe cutting machine (Figure 1) This machine can be used to complete the cutting and car 3 × 30 ° chamfer two processes. For pipe diameter φ76, φ89, φ
