AI Technical Summary

Technical Problem

When existing small resistance welding machines are welded manually by hand plate-shaped workpieces, it is difficult to ensure that the surface of the workpiece and the electrode surface are kept horizontal, resulting in damage to the welding points and affecting welding quality and efficiency.

Method used

A resistance welding machine is designed, using a combination of slide and pushing spring. Pressure is applied to the weldment through a pressurization device to make the slide and plate-shaped welder come into contact with the workpiece and press the workpiece to ensure that the workpiece surface remains horizontal with the electrode surface. After the welding is completed, the workpiece is continued to be pressed by the elastic force of the pushing spring to prevent damage to the welding point.

Benefits of technology

It effectively prevents damage to the welding points of the workpiece that are not completely cooled when taken out, improves welding quality and efficiency, and ensures the firmness of the welding points.

Abstract

The present invention relates to the technical field of welding equipment, and in particular to a resistance electric welding machine, comprising a control system and a pressure device; and also comprising a welding device, wherein the welding device is installed on the pressure device, and the welding device applies pressure to the weldment by the pressure device to drive the slide to contact the plate-shaped weldment and press the weldment by the elastic force of a push spring, and at the same time, the slide slides in the annular groove to drive the rectangular slider to push the push groove, so that the pressing block slides upward to drive the welding head to fit with the surface of the weldment and apply a reverse deformation force to the welding point under the elastic force of the compression spring, so as to prevent the welding point from being deformed when the plate-shaped workpiece is not level with the electrode surface when held manually; the pressure device drives the electrode clamp to move upward to leave the weldment, and the slide clamps the weldment under the elastic force of the push spring until the rectangular slider slides to the bottom end of the rectangular slide groove and releases the weldment, so as to prevent the weldment that is not completely cooled from being damaged when the workpiece is taken out, thereby affecting the quality of the workpiece welding.
