摩擦焊接比常用闪光对接焊具有质量好、废品率低、精度高、功率消耗少、效率高、易于自动化及能改善劳动条件等优点。它可以焊接黑色、有色金属同种或异种材料的工件及某些非金属材料,能以焊代锻,实现少无切削,经济效果显著。在摩擦焊接机上再加装焊接参数监控装置,则更能保证焊接质量。我院负责设计的QLM-4型排气门全自动摩擦焊接机,已由上海练塘机床厂试制成功,经组织鉴定符合需要。该机主要用于直径φ12.5毫米以下排气门的焊接,亦可用于φ20毫米以下的其他低碳钢零件的焊接。并设有切除焊接飞边及自动上下料装置,在结
Friction welding than the common flash butt welding with good quality, low rejection rate, high precision, low power consumption, high efficiency, easy to automate and can improve the working conditions and so on. It can weld black, non-ferrous metals of the same kind or different kinds of materials and some non-metallic materials, to welding forging, to achieve less no cutting, the economic effect is remarkable. Friction welding machine in the welding parameters and then install additional monitoring device, you can better ensure the welding quality. Our hospital is responsible for the design of the QLM-4-type exhaust valve automatic friction welding machine, Liantang Machine Tool Factory from Shanghai trial success, the organization identified in line with needs. This machine is mainly used for the welding of exhaust valves with the diameter of φ12.5mm or less, and also for the welding of other mild steel parts of φ20mm or less. And has cut off the welding flash and automatic loading and unloading device, at the end
