Problems solved by technology
This kind of equipment and method has good welding quality, but the equipment is huge and complicated, the cost is high, and the operation is inconvenient
With this equipment and method, since the double gantry frame is fixed, the station must be fixed, the operating space is small, the placement of the workpiece is troublesome, and the operation is inconvenient; with this equipment and method, it is necessary to add a set of steel plate conveying device and adjustment The cost of the device is relatively high; with this equipment and method, workers cannot visually observe and intervene in the welding process at close range, which increases the difficulty of operation for workers; with this equipment and method, the flux cylinder of the flux distribution and recovery device is placed at a relatively high position Inconvenient to add

Embodiment Construction
[0048] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0049] The invention provides a thin plate splicing submerged arc welding machine, see for details figure 1 , which mainly includes a group of longitudinal guide rails arranged in the workshop. The difference between it and the prior art is that the splicing submerged arc welding machine includes a half-gantry device arranged on a group of longitudinal guide rails. There is a lifting and rotating device between the bilateral pressure frame device and the semi-gantry device; the bilateral pressure frame device ...

The invention relates to a thin plate splicing submerged arc welding machine, which is submerged arc welding equipment for welding two thin steel plates into one steel plate. The splicing submerged arc welding machine includes a semi-gantry device set on a set of longitudinal guide rails, a double-sided pressure frame device is provided under the semi-gantry device, and a lifting and rotating device is provided between the bilateral pressure frame device and the semi-gantry device; The pressure frame device is equipped with an adjustment beam and a welding trolley device, and a weld seam alignment fine-tuning device is installed at both ends. The welding trolley is connected with a flux distribution and recovery device; a grounding device is provided on the semi-gantry. By using this equipment for tailor welding of thin steel plates, it is not only convenient to carry out splicing and welding of thin plates and improve welding efficiency, but also prevent or greatly reduce deformation during steel plate welding and improve welding quality.
Description
technical field [0001] The invention relates to the technical field of steel plate splicing, in particular to a submerged arc welding machine for thin plate splicing. Background technique [0002] At present, in industrial production, two types of welding equipment and methods are mainly used for submerged arc welding of thin steel plates, one is submerged arc welding trolley plus simple guide rail and weight iron, and the other is fixed gantry submerged arc welding plus The way of bilateral bulls pressing. [0003] The method of submerged arc welding trolley plus simple guide rail and pressing iron is to place two steel plates spliced by spot welding on a steel platform with better flatness. According to the length of welding, place pressing iron on one steel plate, A simple guide rail is laid on the surface, and the submerged arc welding trolley is erected on the simple guide rail. Before welding, adjust the parallelism between the simple guide rail and the weld seam, a...
