Description

Technical Field

[0001] The invention relates to the technical field of steel mesh processing, and in particular to an automatic welding device and a welding method for a steel mesh for construction. Background Art

[0002] The steel mesh is made of longitudinal steel bars and transverse steel bars arranged at a certain interval and at right angles to each other, with all intersections welded together. Currently, most steel meshes are welded by steel mesh welding machines. Before welding, the existing steel mesh machines need to feed several transverse steel bars into the feeding end of the steel mesh welding machine through a transverse steel bar feeding device, and on the other hand, the longitudinal steel bars need to be fed one by one onto the transverse steel bars through a longitudinal steel bar feeding device, and then the longitudinal steel bars and the transverse steel bars are welded together through the welding device on the steel mesh welding machine, and finally formed into a steel mesh and then output.

[0003] This welding method requires manual feeding of multiple transverse steel bars into the corresponding transverse steel bar feeding device, which is rather troublesome. In addition, the longitudinal steel bar feeding device uses a circulating belt to feed the steel bars one by one, which is prone to leakage. When the longitudinal steel bars fall on the transverse steel bars, the angle is easily offset, which affects the welding effect. Feeding the steel bars one by one affects the overall welding efficiency. Summary of the invention
