Description

Row welding machine for cabinet processing Technical Field The invention relates to the technical field of gang welders, in particular to a gang welder for cabinet processing. Background In the production and processing of the cabinet body, pipe fittings such as reinforcing ribs and connecting pipes are often welded on the surface of the plate of the cabinet body so as to improve the structural strength, a welding machine is generally adopted at present to carry out the welding operation, the welding machine is high-efficiency automatic metal welding equipment based on the resistance welding principle, the core working mode is that a welded workpiece is pressed between a pair of square electrodes through a pressurizing mechanism such as a cylinder, and then high current is applied, and the welded workpiece is instantaneously heated to a molten or plastic state by utilizing resistance heat of a workpiece contact surface, so that firm connection is realized. At present, although a common cabinet body welding machine is provided with a simple mechanical press arm or a cylinder press block, certain defects still exist, firstly, the pressing position in the welding machine in the prior art is usually fixed or manually preset, the actual joint position difference of each sheet caused by cutting, bending or feeding tolerance cannot be dynamically adapted, the pressing force is often caused to be not precisely acted on the area near a welding line, the pressing effect is unstable, even the pressing effect cannot be achieved, the whole adapting range of the welding machine is limited, secondly, the pressure of a pressing head is usually fixed, the sheet part still can be displaced under the influence of welding heat due to the fact that the sheet part is not effectively restrained, so that the welding machine cannot adapt to the installation position change of pipes with different specifications, the dimensional tolerance or assembly error of the sheet and the pipe is difficult to be compensated, the pressing force application point is inaccurate, the pipe part is not compacted, the welding point is warped at high temperature, and the welding point quality is uneven.
