七十年代到八十年代初,我国自行车行业科技进步工作热火朝天。环型电镀线,Ω油漆线、高频焊管、橡胶棒凸形,气体保护焊等工艺设备相继在那个时期诞生,为自行车行业上产量,上品种、上档次、上质量起到积极的推动作用。然而,近年来自行车行业的技术进步相对步子变慢了。技改费用大大减少,久日不 From the 1970s to the early 1980s, the scientific and technological progress of China’s bicycle industry was in full swing. Circular electroplating lines, Ω paint lines, high-frequency welded pipes, convex rubber rods, gas shielded welding equipment and other equipment were born one after another in that period, and they played an active role in the production of the bicycle industry, in terms of variety, quality, and quality. . However, the relative pace of technological progress in the bicycle industry has slowed down in recent years. The cost of technical reforms has been greatly reduced.
