Benchmark mesh welding device for goods-shelf mesh and welding method thereof

Abstract

The invention belongs to the technical field of wire mesh welding machines and welding methods, and discloses a benchmark mesh welding device for goods-shelf mesh and a welding method thereof. The benchmark mesh welding device for goods-shelf mesh is mainly and technically characterized in that a machine frame is included; an upper beam slide is arranged above the machine frame, an upper beam is arranged in the upper beam slide, an eccentric mechanism with a connecting rod is arranged near and below the machine frame, and the upper end of the connecting rod of the eccentric mechanism is connected with the upper beam; an upper electrode holder communicating with a transformer is fixedly connected with the upper beam, plate type upper electrodes are arranged on the upper electrode holder, and a lower beam is fixed on the portion, located below the upper electrode holder, of the machine frame; and a plurality of elastic top pressure bodies are arranged transversely on the upper beam, a lower electrode holder communicating with the transformer is arranged above the elastic top pressure bodies, upper electrodes are fixed to the upper electrode holder, and a clapping and leveling mechanism is arranged on the outer side of the machine frame. In the welding process, the pressure between an organzine and a tram in each welding sport is almost equal, welding quality is high, and mesh flatness is good.

Description

technical field [0001] The invention belongs to the technical field of a metal mesh welding device and a welding method, and in particular relates to a welding device and a welding method for a shelf net reference mesh. Background technique [0002] Displaying items in supermarkets, item display and other places requires a large number of shelf nets. The mesh of the shelf net includes a reference mesh composed of a warp with a smaller diameter at the bottom and a weft with a larger diameter in the middle. There are short wires in the same direction as the warp on the upper side, and there are two short wires on one side. At present, the wire mesh welding machine mainly includes an upper beam and a lower beam. The upper welding head is fixed on the upper beam through an elastic compression spring. The upper beam can move up and down, while the lower beam is fixed with the frame, and the lower welding head is fixed on the lower beam. On the beam, during welding, when the uppe...

AI Technical Summary

Problems solved by technology

When using the above-mentioned ordinary welding machine to weld the reference mesh of the shelf net, there are the following defects: First, because the lower electrode is easy to wear during the production process, and the degree of wear of each lower electrode is inconsistent, the warp wire on the lower electrode with serious wear The position is lower than the warp on other lower electrodes. Second, during the machining process, due to the influence of machining accuracy, the flatness of the lower beam and the cumulative error of each part, the lower electrodes are not on the same level.

In this way, during the pressing process of the upper electrode, due to the large diameter and high strength of the weft wire, it is not easy to bend, resulting in uneven pressure on each solder joint, affecting the flatness of the mesh, and it is easy to cause warping at the lower warp wire. wire burn
