ELECTRODE TIP SHAPING DEVICE AND ELECTRODE TIP SHAPING TOOL

摘要

An electrode tip shaping device for a resistance welder enabling a reduction in size by reducing the rotatingly driving force of electrode tip shaping tools and the electrode tip shaping tools. Since the radius of curvature of the shaping parts (4) of the shaping tools (2) is adjusted to adjust the contact width of the tips (5) of the electrode tips on the shaping parts (4) of the shaping tools (2) starting at the rotating center of the shaping tools (2) to the outside, a shaping work performed by the shaping tools (2) can be uniformized in all the areas of the shaping parts (4) starting at the rotating center of the shaping tools (2) to the outside. Accordingly, a loss by an excess shaping work can be eliminated and the tips (5) of the electrode tips can be shaped by the minimum shaping work. Thus, since the rotatingly driving force of the shaping tools (2) is reduced, the electrode tip shaping device can be so formed that labor can be saved and the size can be reduced.
