近年来软管自动电焊已广泛应用于生产上,该设备由焊接电源(变压器或直流电焊机)、配电箱、送丝机构、软管及手把等组成(见图1)。它主要是由送丝机构将焊丝送入软管,通过手把的导电嘴向焊缝方向送进。这种设备虽然很好,但是在应用上及加工制造方面也有下述不方便的地方: 软管半自动焊设备的结构比较复杂,附件多,加工较力困难,尤其是36伏的小电动机、36伏的变压器、送丝机构的齿轮箱、空心软管,及一整套的控制线路等,在一般技木条件差的厂根本不能制造;并且在操作方面,由于送丝机构离开工件有一定的距离,要使2毫米的焊丝通过一根3.5米
In recent years, automatic hose welding has been widely used in the production of the equipment by the welding power source (transformer or DC welding machine), distribution box, wire feeding agencies, hoses and handgrips and other components (see Figure 1). It is mainly by the wire feeding mechanism into the hose, through the hand of the conductive nozzle to the weld direction. Although this kind of equipment is very good, there are some inconveniences in terms of application and manufacture as follows: Hose semi-automatic welding equipment has complicated structure, many attachments and difficult processing, especially small 36-volt motor, 36 Volt transformer, wire feeding gear box, hollow hose, and a full set of control lines, etc., in the general poor technical condition of the plant simply can not manufacture; and in operation, as the wire feeding mechanism to leave the workpiece a certain distance , To make 2 mm wire through a 3.5 meters
