Abstract

Provided is a shaping device (10) for a roller electrode for seam welding that prepares shapes for a first roller electrode (17) and a second roller electrode (23) attached to an arm (49) of a robot (48). This shaping device is provided independently from the robot and disposed within rotational range of the arm, and is provided with a first roller (12) and a second roller (13) that are disposed on a line orthogonal to a line joining the rotational centers of the first and second roller electrodes and are in contact with the outer circumferences of the first and second roller electrodes.

Description

technical field [0001] The invention relates to a shaping device and a shaping method of a roller electrode for seam welding. Background technique [0002] Hold multiple metal plates with a pair of roller electrodes. A welding current flows between these roller electrodes. Then, the metal is melted by Joule heat to form a weld between the metal plates. By rotating the roller electrode, a linear weld called a seam is obtained. [0003] In seam welding, the roller electrode is pressed against the sheet metal. On this basis, the roller electrode becomes high temperature due to Joule heat. Due to pressure and temperature, wear and plastic deformation (hereinafter referred to as deformation) of the roller electrode increase in proportion to the use time and frequency of use. When the deformation reaches a certain limit or periodically, a process for restoring the shape of the roller electrode is performed. This processing is called "shaping". [0004] The welding manipulat...
