AI Technical Summary

Technical Problem

During resistance welding, spatter generated during welding may adhere to the inner wall of the protective cover and drip back onto the workpiece surface, affecting the welding quality.

Method used

An intelligent resistance welding device including an anti-splatter component, an extrusion component, and a cooling component was designed. The device collects spatter impurities through an inclined baffle and uses the baffle and cooling plate for rapid cooling and replacement to prevent impurities from dripping. At the same time, the extrusion component ensures the stability of the welding process.

Benefits of technology

This effectively prevents splashing impurities from dripping directly onto the workpiece surface, ensuring welding quality. Furthermore, by reducing the impact of impurities through cooling and replacing baffles, the stability and efficiency of welding are achieved.

Abstract

This invention discloses a low-spatter intelligent resistance welding device for manufacturing automotive harmonica tubes, belonging to the technical field of intelligent welding systems. It includes a support base with a first electric push rod at one end. By incorporating anti-spatter components, this design allows for the sealing of the outer shell by moving the cover plate to one side during harmonica tube welding. If spatter occurs during welding, the spattered impurities will fall onto the surfaces of the first and second partitions. Since both partitions are tilted, the molten impurities will descend along the slope, preventing them from directly dripping onto the harmonica tube surface. Furthermore, when excessive impurities adhere to the surfaces of the first and second partitions, they can be removed and replaced.
