Problems solved by technology

Although both can realize push-pull wire feeding, both have disadvantages. The mechanical structure is complex and the inertia is large. The stepping or servo rotary motor push-pull system needs to increase the welding wire coordination mechanism between the wire feeding motor and the push-pull motor, so that the whole is bulky and complicated. , the control is not convenient enough

Abstract

The invention provides a vibrating wire feeding welding device based on a linear motor, and belongs to the technical field of welding equipment. The device specifically comprises wire feeding box body, a linear motor unit, an insulation plate, a wire feeding running pipe assembly, a connector, a wire feeder unit, a welding wire and a welding wire plate, wherein the wire feeding box comprises a side frame, a box chassis and a box side wall; the linear motor unit consists of a stator and a rotor; the stator is fixed to the box chassis; the wire feeder unit is fixed to the rotor through an the insulation plate; one end of the wire feeding running pipe assembly is connected with the connector and fixed on the side wall of the box body, and the other end of the wire feeding running pipe assembly is mounted on the wire feeder unit; and the wire welding plate is hung on a side frame of the box body and supports wire feeding. The wire feeder unit receives a constant speed command to enable thewelding wire to be fed forwards at a constant speed, and after the linear motor unit receives a vibration command, the mover drives the wire feeder unit to enable the welding wire to be pushed forwards and drawn back backwards, so that the effect of vibration wire feeding is achieved. The device achieves the purposes of reducing heat input and welding defects.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a linear motor-based vibrating wire-feed welding device, which is mainly used in metal gas shielded welding, which can reduce the overall heat input and improve the quality of weld seam formation. Background technique [0002] Gas metal arc welding (GMAW) is a welding method that uses the arc generated between the welding wire and the workpiece as a heat source to melt the metal under the protection of inert gas or active gas. This method can weld most metals and their alloys, but in the welding process, due to the complex factors involved, the unreasonable setting of parameters such as welding voltage, current, wire feeding and welding speed, it is easy to cause cracks, pores, and penetration in the weld metal and spatter and other welding defects. Wire feeding is a very important operation link in the welding process. In molten electrode welding, the perf...
