Title:
CUTTING TOOL AND METHOD FOR MAINTAINING WELDING ELECTRODE HAVING A CENTRAL DEPRESSION
Document Type and Number:
WIPO Patent Application WO/2020/221362
Kind Code:
A1
Abstract:
A cutting tool and a method for maintaining a welding electrode having a central depression. The cutting tool comprises a main body (1) and cutting components (2). The cutting components (2) are disposed in the main body (1) and comprise one or more cutting blades (21, 22). The cutting blades (21, 22) are distributed radially around the central axis of the main body at equal intervals. The cutting blades (21, 22) partition the main body into a plurality of cutting cavities (80a, 80b, 80c, 80d). Two cutting cavities are formed by the axial outer side surfaces of two ends of each cutting blade and the main body. At least one axial outer side surface of each cutting blade is provided with a cutting edge (3400). A protrusion is provided on the middle of each cutting edge. The axial projection shape of the protrusion is the same as the cross-sectional shape of the central depression of a welding electrode. The cutting tool can perform maintenance accurately, quickly and regularly to restore the original welding surface shape of the welding electrode having a central depression, thereby keeping a high welding quality and ensuring the normal and orderly progress of production activities.
