Brazing welding tool

Abstract

The invention relates to the technical field of welding machining, in particular to a brazing welding tool. The brazing welding tool comprises a base, a rocking curved rod, an extrusion plate, a fixing plate and a clamping unit; the clamping unit comprises first pressing plates, second pressing plates, push rods, airbags and cleaning brushes; the push rods are installed on the side walls, close tosprings, of the first pressing plates; the cleaning brushes are symmetrically installed on the side walls of the top ends of the extrusion plate and the fixing plate, and the bottom ends of the cleaning brushes communicate with the airbags through rubber pipes; and through cooperation of the base, the rocking curved rod, the extrusion plate, the fixing plate and the clamping unit, the side wall of a blank can be clamped, the cleaning brushing effect on the side wall of the blank is achieved, the situation that after a thick oxidation layer adheres to the surface of the blank, the brazing welding quality is influenced is avoided, accordingly, the brazing welding difficulty is further reduced, meanwhile, great convenience is brought to workers, and the position accuracy of the blank in thewelding process is ensured.

Description

technical field [0001] The invention relates to the field of welding processing technology, in particular to a brazing welding tool. Background technique [0002] Brazing refers to a welding method in which the solder below the melting point of the weldment and the weldment are heated to the melting temperature of the solder at the same time, and the gap between the solid workpiece is filled with liquid solder to connect the metal; when brazing, the base metal must first be removed Oxide film and oil stains on the contact surface are used to facilitate the function of the capillary after the solder melts, increasing the wettability and capillary fluidity of the solder; according to the melting point of the solder, brazing is divided into hard brazing and soft soldering Welding; brazing deformation is small, the joint is smooth and beautiful, suitable for welding precision, complex and components composed of different materials, such as honeycomb structure plates, turbine bla...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, to solve the problem that during the brazing process, if the required welding raw materials have a high melting point, manual clamping by the staff cannot be performed at this time. Generally, induction welding guns are used for welding. Due to the high temperature, The staff cannot remove the oxide film produced by the high temperature on the surface of the blank in time, which seriously affects the welding quality of brazing.
