Welding mechanism capable of adjusting longitudinal bar spacing automatically on wire welding machine

Abstract

The invention discloses a welding mechanism capable of adjusting longitudinal bar spacing automatically on a wire welding machine. The welding mechanism comprises an upper beam, a lower beam and a machine frame, wherein a plurality of independent welding units are installed on the upper beam in a sliding fit mode, a welding electrode set composed of a lower electrode and an upper electrode is arranged in each independent welding unit, a positioning device is arranged on each independent welding unit to position the independent welding unit, interlocking devices are arranged between every two adjacent independent welding units to enable the independent welding units to be locked or loosened, and the independent welding unit at the tail end of the plurality of independent welding units is connected with a traveling device which is arranged on the upper beam. The welding mechanism capable of adjusting the longitudinal bar spacing automatically on the wire welding machine has the advantages that the lower electrode and the upper electrode are arranged in each independent welding unit, the independent welding units are driven by the traveling device to adjust the longitudinal bar spacing freely when a weld mesh crate is changed, therefore, adaptability is strong, labor intensity of operators is relieved, adjustment is convenient, automatic production is achieved, welding efficiency is improved, and the independent welding units are convenient to maintain.

Description

technical field [0001] The invention relates to a wire mesh welding machine, in particular to a welding mechanism for automatically adjusting the distance between longitudinal ribs on the wire mesh welding machine. Background technique [0002] The welding mesh machine is a special equipment for welding the longitudinal and transverse bars together through electrodes to form a metal grid. In the prior art, the upper and lower electrode holders of the welding machine are respectively equipped with upper and lower electrodes, and the upper and lower electrode holders are fixed on the frame through dovetails; when adjusting the distance between longitudinal ribs, it is necessary to loosen the fasteners on each upper and lower electrode holders respectively , Manually move the electrode seat to a suitable position to complete the adjustment of the upper and lower electrode positions, and then tighten the fasteners to fix the upper and lower electrode seats. [0003] The structu...
