High-frequency welding mechanism and method of wire feeding machine

Abstract

The invention discloses a high-frequency welding mechanism and a method of a wire feeding machine. A workpiece tool, a cylinder adjusting mechanism, a wire feeding mechanism and a brazing device are arranged on a worktable; workpieces to be machined are fixed on the workpiece tool positioned at the lower end of an induction coil; the electromagnetic induction heating is performed on the workpiecesto be machined through the induction coil on the brazing device; a control system controls a cylinder device on the cylinder adjusting mechanism to feed a wire feeding nozzle onto the workpieces to be machined; a force sensor induces if welding wires are molten to achieve accurate wire feeding; the wire feeding mechanism, the brazing device and the force sensor are matched to realize precise matching between the welding wires and welded parts, so that the operation efficiency and the convenience are improved; a control system is adopted to replace manual control, so that full automation of all actions is guaranteed; the welded parts and the welding wires are precisely matched to reach optimal product quality; and the mechanism can adopt single-station and multi-station welding operations,can perform mated use according to actual scene conditions, and solves the product welding problems.

Description

technical field [0001] The invention belongs to the technical field of high-frequency induction high-frequency brazing, and relates to a high-frequency welding mechanism and a control method of a wire feeder. Background technique [0002] The welding of pipe joints in the air-conditioning and refrigeration industry requires a wire feeder and high-frequency equipment for welding operations. Traditional welding is designed with flame and wire feeder, which not only needs to constantly adjust the flame pressure to ensure the stability of the product, but also the gas is not fully combusted, which increases costs and pollutes the environment, which is not conducive to reducing production costs and ensuring product stability. sex. [0003] In the existing welding mechanism, the flame pressure is unstable during the welding process, and the temperature is easily unstable. The welding wire does not melt at the beginning of wire feeding, and there are problems such as welding wire ...

AI Technical Summary

Problems solved by technology

Traditional welding is designed with flame and wire feeder, which not only needs to constantly adjust the flame pressure to ensure the stability of the product, but also the gas is not fully combusted, which increases costs and pollutes the environment, which is not conducive to reducing production costs and ensuring product stability. sex

[0003] The flame pressure of the existing welding mechanism is unstable during the welding process, and the temperature is prone to instability. The welding wire does not melt at the beginning of wire feeding, and problems such as welding wire deviation or insufficient solder volume occur, and the best quality of the product cannot be guaranteed.
