Problems solved by technology

[0002] In the production and manufacture of cryogenic containers, copper pipes and stainless steel pipes are often welded. Some welded parts are used at a low temperature of -196°C, which requires high welding quality and requires liquid nitrogen -196°C cold shock and The destructive test, if the conventional welding method is used, basically cannot meet the performance at low temperature, so the important welding parts are completed by induction brazing, but the temperature on the workpiece is very high when the induction brazing is used to weld the pipe fittings , the operator cannot support the workpiece with his hands, and the workpiece cannot be positioned quickly and accurately, which affects the welding quality and welding efficiency

Abstract

The invention discloses a welding tool for induction soldering pipe fittings. The welding tool comprises a base plate, two stand columns, a supporting plate and a lifting table. The two stand columns are fixed to the base plate in parallel in a spaced mode. The supporting plate is fixed to the top ends of the two stand columns. The lifting table is arranged in the middles of the two stand columns in a height-adjustable mode. A through hole is formed in the lifting table. An induction coil of an induction soldering machine is arranged at the portion, between the two stand columns, above the lifting table. One end of the inner pipe fitting to be welded is connected to the supporting plate through a connecting assembly, and the other end of the inner pipe fitting to be welded penetrates through the induction coil, the outer pipe fitting to be welded and the through hole. The outer pipe fitting to be welded is arranged at the portion, outside the inner pipe fitting to be welded, of the lifting table through a limiting assembly. The welding tool for the induction soldering pipe fittings is simple in structure and convenient to operate, the welding efficiency is improved, and welding reliability and reliability are ensured.

Description

technical field [0001] The invention relates to a welding tool, in particular to a welding tool for induction brazing pipe fittings. Background technique [0002] In the production of cryogenic vessels, copper tubes and stainless steel tubes are often welded. Some welded parts are used at a low temperature of -196 °C, which requires high welding quality and needs to undergo cold shock and cold shock of liquid nitrogen at -196 °C. Destructive test, if the conventional welding method is used, it basically cannot meet the performance at low temperature, so induction brazing is used for important welded parts, but the temperature on the workpiece is very high when induction brazing is used to weld pipe fittings , the operator cannot support the workpiece by hand, and the workpiece cannot be positioned quickly and accurately, which affects the welding quality and welding efficiency. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a welding ...
