Wire feeding device of automatic welding machine

Abstract

The invention relates to the technical field of welding machines, in particular to a wire feeding device of an automatic welding machine. The wire feeding device comprises a shell, a protective door is hinged to the front side of the shell, bases are bolted to the left side and the right side of the bottom of the shell, a partition plate is bolted to an inner cavity of the shell, a connecting disc is bolted to the inner cavity of the shell, and the connecting disc is located on the left side of the partition plate. According to the wire feeding device, through the arrangement of the connecting disc, a disc shaft, a motor, a speed change mechanism, wire feeding wheels, pressing rollers and a control panel, the wire feeding device has the advantages that a fed welding wire cannot be bent, the wire feeding stability can be improved, the welding quality of the automatic welding machine can be improved, and meanwhile the wire feeding speed, the wire feeding time and the withdrawing speed can be set; and the problems that a wire feeding device used by an existing automatic welding machine is poor in practicability, unstable in wire feeding and poor in wire feeding uniformity, so that the quality of a welding seam is seriously affected, and a welding wire is likely to adhere to a welding material are solved.

Description

technical field [0001] The invention relates to the technical field of welding machines, in particular to a wire feeding device of an automatic welding machine. Background technique [0002] The wire feeding device plays an important role in the entire automatic welding machine system, especially the stability, reliability, continuity and efficiency of the weld. The quality of the weld seam of welding products depends to a certain extent on the thickness of the welding layer. If the welding thickness is inconsistent, the surface of the product may be raised, causing the surface to be rough. The common feeding mechanism has unstable wire feeding and poor uniformity, resulting in poor weld quality. [0003] At present, the wire feeding device used in the automatic welding machine has poor practicability, unstable wire feeding and poor uniformity of wire feeding, which seriously affects the quality of the weld seam, and the wire feeding device cannot quickly brake and withdraw...

The common feeding mechanism has unstable wire feeding and poor uniformity, resulting in poor weld quality

[0003] At present, the wire feeding device used in the automatic welding machine has poor practicability, unstable wire feeding and poor uniformity of wire feeding, which seriously affects the quality of the weld seam, and the wire feeding device cannot quickly brake and withdraw when the operation is stopped. The wire tip will cause the welding wire to easily stick to the welding material. Therefore, we propose a method that can prevent the sent welding wire from bending, improve the stability of the wire feeding, and help improve the welding quality of the automatic welding seam machine. At the same time, it can control the wire feeding speed, Wire feeding device with wire feeding time and withdrawal speed can be set to solve this problem
