Abstract

The invention discloses a reinforcement cage welding tool and a fixed electrode thereof. The fixed electrode of the reinforcement cage welding tool comprises an electrode base body and a conductive part. The electrode base body is mounted at one end of a seam welder spindle. The conductive part is detachably and fixedly mounted on the electrode base body. A peripheral contour base line of the conductive part is matched with a peripheral contour base line of a reinforcement cage workpiece to be welded. The conductive part is provided with locating structures for reinforcement cage workpiece main reinforcement steel bars and can be electrically connected to one power output end of the welding tool through the electrode base body or a conductive mechanism arranged on the electrode base body.Through the reinforcement cage welding tool and the fixed electrode thereof, the problem that a fixed electrode is corroded in the manufacturing process of a reinforcement cage and needs to be integrally replaced is solved, and the purpose of reducing the production cost is achieved.

Description

technical field [0001] The invention relates to a reinforcement cage welding tool and a fixed electrode thereof, belonging to the technical field of welding equipment. Background technique [0002] Inside various piles, columns, beams and other components in construction projects, it is necessary to set up a steel skeleton (commonly known as a steel cage) to restrain the concrete to ensure the integrity of the concrete components. For example, during the construction of cast-in-situ piles for bridges and high-rise buildings, it is necessary to place reinforcement cages in foundation pile holes to enhance the tensile performance of cast-in-situ piles. The reinforcement cage includes a plurality of main reinforcements extending in the same direction and stirrups arranged perpendicular to the extension direction of the main reinforcements or spirally surrounding them. The stirrups are fixed to the outer or inner circumference of the main reinforcements by welding. According to ...
