Butt welding machine high-strength lower clamp

Abstract

The invention relates to a high-intensity lower jig for butt welders, which is characterized in that two sets of lower jig engaging lugs (2) are cast on a permanent seat mounting plate (3); a fixed support block (4) is cast between the two lower jig engaging lugs (2); a horizontal plane of a copper electrode seat (5) in a shape of '7'is arranged on the fixed support block (4); a vertical plane ofthe copper electrode seat in the shape of 7 is laterally provided with a cooling pipe (6); a plurality of threaded holes (7) are arranged on the vertical plane beneath the cooling pipe. The high-intensity lower jig for butt welders has the advantages of high intensity, shock resistance, convenient assembly, firm locking, resistance to damage, flexible operations, fine conductibility and long service life.

Description

technical field [0001] The invention relates to a high-strength clamp for a butt welding machine, in particular to a lower clamp for welding fixed steel bars on a butt welding machine. Background technique [0002] The butt welding machine is a commonly used welding equipment for building steel bars. It is mainly composed of upper and lower clamps, screw pressurization devices, main transformers, and connecting components. , high temperature and high pressure in the welding area, the screw pressurizing device exerts a large external force on the upper and lower fixtures, and has higher requirements on the strength and service life of the upper and lower fixtures. The upper fixture of the upper and lower fixtures of the existing butt welding machine is movably installed on the two sets of connecting ears of the lower fixture, and the fixing seat mounting plate of the lower fixture is installed on the fixing seat. The copper electrode seat is in an inverted "T" shape, and its ...

AI Technical Summary

Problems solved by technology

The upper fixture of the upper and lower fixtures of the existing butt welding machine is movably installed on the two sets of connecting ears of the lower fixture, and the fixing seat mounting plate of the lower fixture is installed on the fixing seat. The copper electrode seat is in an inverted "T" shape, and its horizontal surface passes through the screw Locked on the bottom surface of the mounting plate of the fixed seat, the vertical surface is located between the two sets of connecting ears of the lower fixture. After frequent impacts by the screw pressurization device, the locking place between the copper electrode seat and the bottom surface of the mounting plate of the fixed seat is easy to loosen and contact Poor, after long-term use, the horizontal surface of the copper electrode seat is easy to break, low strength, no pressure resistance, easy damage, short service life, affecting the normal use of the butt welding machine
