Abstract

Provided are an induction welding device and method for sectional materials. The device comprises an induction welding device body, a PLC control system, a hydraulic system, a cooling system and an induction heating power supply, and further comprises a left mounting plate, a right mounting plate and two sub-coils. The method includes the following steps that two pieces of sectional materials to be welded are located through locating pieces installed on the lower portion of a center shaft of the induction welding device body in a connected mode; a clamping oil cylinder drives two sets of clamp bodies to rotate around the center shaft respectively to clamp and center the sectional materials to be welded; an opening-closing induction heating coil moves the butt joint of the sectional materials with the help of an auxiliary oil cylinder, a locating oil cylinder pushes and wraps the two sub-coils and makes contact with an electrode structure; the PLC control system starts the induction heating coil to heat; when the preset welding temperature is reached, the induction heating power supply is closed, the locating oil cylinder separates the two sub-coils, and an upset forging oil cylinder applies set upset forging force in a heating process of the but joint of the sectional materials all the time to enable end faces of the sectional materials to be welded together; a jaw opens, and the sectional materials are loosened. The induction welding device achieves automatic operation and is high in efficiency.

Description

technical field [0001] The invention relates to the welding technology of profiles, in particular to induction welding equipment and methods. Background technique [0002] At present, resistance contact welding, induction welding, and friction welding used for common rails, steel bars, steel pipes, channel steel and other profiles all belong to the category of pressure welding. Pressure welding does not need to be filled with welding materials during the welding process, and it is low-consumption and environmentally friendly. Friction welding is limited by the power of the spindle motor, so it cannot weld large cross-section profiles; while contact flash welding, which is widely used at present, is difficult to control the current density of the lintel, contact resistance, and depth of the fire hole, and it is easy to generate welding defects such as gray spots , will have a greater impact on the quality and life of the welded joint. On the other hand, there are many monit...
