Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to a lead arm structure of a semi-automatic micro spot welding machine. Background Art

[0002] A micro-spot welder is a small, lightweight and efficient resistance welding device. The following is a detailed introduction to the micro-spot welder: The micro-spot welder uses the electrothermal effect to convert electrical energy into thermal energy, thereby achieving the welding of metal materials. Specifically, it uses current to transfer to the weldment through the electrode to form an arc. Through the high temperature of the arc, the metal material is locally melted, and then cooled and solidified to achieve welding. During the welding process, parameters such as power supply, current control, electrode contact, heat transfer, melting and cooling, and pressure control are precisely controlled to ensure the quality and effect of welding.

[0003] The welding wire is not pulled smoothly, and the wire pulling mechanism has design defects: When the semi-automatic micro-spot welding machine is pulling the welding wire, if the pulling mechanism is not designed reasonably, the wire may get stuck or twisted during the pulling process. This situation will increase the risk of wire breakage and affect the continuity and quality of welding. The wire material does not match the pulling speed: different welding wires have different hardness and toughness. If the pulling speed is too fast or too slow, the wire may not be able to adapt to the pulling force and break. Therefore, it is necessary to select a suitable pulling speed according to the material and characteristics of the wire. The substrate movement is not efficient. The wear of the traction mechanism may cause the wire to be pulled unevenly; the wear of the moving mechanism may cause the substrate to move inaccurately. Utility Model Content
