Induction braze welding device for irregular parts

Abstract

The invention discloses an induction braze welding device for irregular parts. The induction braze welding device comprises a strip-shaped electromagnet, a protection cover, a clamp, a base and an induction heating power supply, wherein the base is welded at the bottom end of one side of an outer side wall of the induction heating power supply; two sliding grooves, which are parallel to each other, are formed in the outer side wall of the induction heating power supply above the base; the sliding grooves are in sliding connection with fixed plates vertical to the induction heating power supplythrough sliding blocks. According to the induction braze welding device for the irregular parts, disclosed by the invention, a heating plate is fixed at the inner side of the protection cover, and heat conducting fins, which extend into an evaporation chamber, are uniformly distributed at the outer side of the heating plate and can be used for collecting a magnetic field at the outer side of thestrip-shaped electromagnet and heating by utilizing the heating plate in a process of heating a workpiece, so as to absorb radiation heat generated by the workpiece; the magnetic field generated in anelectrifying process of the strip-shaped electromagnet is sufficiently utilized and the utilization rate of electric energy is increased; influences, caused by the fact that the heat of the workpieceis too high, on the external environment are avoided and the radiation of heat of the workpiece is hindered.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an induction brazing device for irregular parts. 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 contact with the base metal must first be removed. Oxide film and oil on the surface, in order to facilitate the function of the capillary after the solder melts, increase the wettability and capillary fluidity of the solder, according to the different melting points of the solder, brazing is divided into hard brazing and soft soldering . [0003] Induction brazing is a welding method that uses high-frequency, medium-frequency or power-frequency induction current as a heat source. High-frequency heating is suitable...

Problems solved by technology

[0005] The object of the present invention is to provide an induction brazing device for irregular parts, to solve the problem that the existing induction brazing device proposed in the above background technology cannot ensure that the placement position is located inside the coil due to the placement of the workpiece during use. In the middle of the coil, it is easy to be heated unevenly during the heating process, and due to the limitation of the internal magnetic field of the ring coil, only tubular parts can be welded, which easily makes the workpiece heated unevenly, and it is not convenient to heat irregular parts. , and in the process of use, the power consumption during the coil electrification process cannot be fully utilized, the energy consumption is large, and the production cost is increased.
