线式送丝机构是近年来国外为适应造船、大型结构的气体保护焊长距离推送大直径的药芯焊丝或长距离输送小直径有色金属焊丝的需要,而发展起来的一种新型送丝机构。据有关资料介绍,大约在一九六九年美国霍巴特兄弟公司就开始研制新型的送丝系统,它使用小型永磁马达,在马达的主轴上装有小型的送丝机构,送丝机构与马达电枢的中心位于一条直线上,使焊丝通过马达电枢的中空轴,这种直线排列的形式就构或了线式送丝系统。
In recent years, the wire wire feeding mechanism is a new type of wire feeding mechanism developed to meet the needs of long-distance large-diameter flux-cored welding wire or long-distance conveying small-diameter non-ferrous metal wire for gas shielded welding of shipbuilding and large-scale structures. . According to relevant information, about 1969, the United States, Hobart Brothers started to develop a new wire feeding system, which uses a small permanent magnet motor, the spindle motor is equipped with a small wire feeding mechanism, wire feeding mechanism and the motor The center of the armature is located on a straight line, passing the wire through the hollow shaft of the motor armature. This linear arrangement forms the wire feed system.
