闭合式磁力接头在电焊机地线上的应用

Application of auto-close magnetic terminal in welding machine ground line

传统电焊机焊接地线与工件接触端接触点少,易使电缆发热烧损;地线与工件接触不良易使高精度工件表面损坏造成应力集中,降低焊接质量;高处作业时焊工手持焊接地线作业,存在安全隐患。为了解决这些问题,将可闭合式磁力器进行改造作为地线接头,这样可解决地线接头与焊接工件之间导电不良的问题。该接头结构简单,使用方便,最大限度地保证了焊接回路电流的畅通和工件表面的清洁。由于在焊接过程中没有了因地线位置放置不当产生的磁偏吹,焊接质量也大为提高。在高空作业时,有效减少了弧光和飞溅对焊工的伤害,也在一定程度上降低了高空作业带来的风险。

To solve the problem of the traditional grounding cable that the contact point between the grounding calbe and the weldment is too few,which leads to the damage to the cable because of its overheating,the problem that the poor contact between the grounding cable and the weldment causes the saburface damage of high-precision weldment as well as the concentration of the stress,which reduces welding quality,and also the problem that welders who hold welding grounding cable in the high places may suffer from potential safety hazard,we can rebuild the auto-close magnetic separator as the ground wire terminal which avoids the poor electricity conduction between grounding cable terminal and the weldment.This terminal is simple and convenient to operate,which guarantees the good connection of the welding circuit and keeps clean the surface of the weldment.During the course of operating,the welding quality is greatly improved due to the avoiding of improper position of the grounding cable,which causes magnetic blow.During safe aerial work,it reduces the hurting of the arc and splash to the welders,and brings down the risk it brings to the high-place operating.
