Fixed electrode insulating mechanism of sliding welding machine

Abstract

The invention provides a fixed electrode insulating mechanism of a sliding welding machine, wherein, the outer side of the fixed electrode is fixedly installed with a plurality of insulation boards; the spacing between insulation boards corresponds to a guide rib tank which is arranged on the fixed electrode; a base body of the fixed electrode is installed with a plurality of guide rib tank bodies which are provided with the guide rib tank; the back cut surface of the guide rib tank body is flush with the outer surface of the insulation board or is lower than the outer surface of the insulation board; or the two sides of the back cut surface of the guide rib tank body are provided with platforms; the insulation boards are arranged on the platforms to shorten as possible the distance between the outer side of the back cut surface guide rib tank of the guide tank body and the guide tank body, thus ensuring that when the electrode body is in a welding station, effective contact between aelectrode body and a hooping, a longitudinal rib, the fixed electrode can be realized; when the electrode is not in the welding station, the electrode body and the fixed electrode can be insulated effectively as the hooping is deformed and concaved downward by the acting force which is carried out by the electrode body on the hooping between two longitudinal ribs, thus eradicating the generation of heavy current energy wastage or even device burning-out by the direct contact between the electrode body and the fixed electrode.

Description

Technical field: [0001] The invention relates to welding equipment, in particular to welding elongated metal cages formed by cross-welding of metal ribs, such as fixed electrodes in electrode parts of welding equipment such as reinforcement cages for concrete components. Background technique: [0002] The existing roll welding equipment for long metal cages, such as the welding equipment for steel cages for concrete pipe piles, is designed for concrete pipe piles. There are several grooves for guiding ribs, and the fixed electrodes are fixed on the bracket. Since there are only longitudinal bars and stirrups of the metal cage between the fixed electrode and the electrode body of the movable electrode, and the electrode body is not in the welding station, the force exerted by the electrode body on the stirrup between the two longitudinal bars causes the stirrup to change. When the shape is concave, the electrode body directly contacts the fixed electrode through the stirrup ...

AI Technical Summary

Problems solved by technology

Since there are only longitudinal bars and stirrups of the metal cage between the fixed electrode and the electrode body of the movable electrode, and the electrode body is not in the welding station, the force exerted by the electrode body on the stirrup between the two longitudinal bars causes the stirrup to change. When the shape is concave, the electrode body directly contacts the fixed electrode through the stirrup to generate a large current, resulting in waste of energy, and may seriously burn out the equipment
