Welding wire winding machine capable of automatically controlling lag angles

Abstract

The invention relates to a welding wire winding machine capable of automatically controlling lag angles. According to the technical scheme, a wire take-up mechanism and a wire arranging mechanism of the welding wire winding machine are arranged in parallel; a first variable-frequency motor (1) of the wire take-up mechanism and a shaft of a wire winding plate (12) of the wire take-up mechanism are connected; two guide rods (6) of the wire arranging mechanism penetrate through corresponding through holes of a mobile platform (7), and a left limit switch (2) and a right limit switch (11) are correspondingly installed at the parts, close to the two ends, of one guide rod (6); a screw rod (5) in threaded connection with the mobile platform (7) is connected to a shaft of a second variable-frequency motor (3), the mobile platform (7) is fixedly connected to the rear end of a swinging strip-shaped plate (9) through a supporting shaft (18), an angular displacement sensor (17) on the mobile platform (7) is fixedly connected to the swinging strip-shaped plate (9) through a connecting rod (16), and guide devices (8) are symmetrically installed at the two ends of the swinging strip-shaped plate (9). The welding wire winding machine has the advantages that error accumulation is small, the adaptation range of the diameters of welding wires is wide, the wire arranging stroke is easy to adjust and control over the lag angles is accurate.

Description

technical field [0001] The invention belongs to the technical field of welding wire layer winding machines. In particular, it relates to a welding wire layer winding machine which automatically controls the lagging angle. Background technique [0002] When using welding wire for arc welding, the welding current is often adjusted according to the speed at which the welding wire is fed. Therefore, whether the feeding of the welding wire is stable or not will directly affect the stability of the arc combustion and the formation of the weld seam. To achieve stable wire feeding, the finished wire must be wound in precise layers. The layer winding of welding wire is the most labor-intensive process in the welding wire production process. The wire arrangement mechanism is one of the keys to determine the working efficiency of the layer winding machine. The best wire arrangement mechanism should meet: [0003] 1. The reciprocating cycle of the wire arrangement mechanism is strict...
