Shipyard thin plate splicing butt-joint laser hybrid welding system

Abstract

The invention discloses a shipyard thin plate splicing butt-joint laser hybrid welding system which is characterized in that a laser hybrid welding spliced plate pressure frame is arranged between a feeding platform and a discharging platform; the laser hybrid welding spliced plate pressure frame is composed of an adjustable liner plate, a grounding device, a piano key type pressing unit, a milling device, a recycling system and a welding device; the adjustable liner plate and the grounding device are arranged between two fixed gantries; the feeding platform pushes a thin plate to a welding station of the laser hybrid welding spliced plate pressure frame through a clamping frame, and spliced plates are automatically welded through the welding device and then sent out of the system throughthe discharging platform, so that the automatic line production of spliced plate butt joint is achieved. Compared with the prior art, the shipyard thin plate splicing butt-joint laser hybrid welding system provided by the invention integrates thin plate splicing, milling and welding, is simple in structure and good in compatibility, and is used for the spliced plate butt-joint automatic welding ofthe plane thin plates in the shipyard plate hull manufacturing and machining process, so that the production efficiency of thin plate splicing and welding can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of jigsaw butt welding, in particular to a shipyard thin-slab jigsaw butt welding laser composite welding system. Background technique [0002] Thin plate units with plate thickness below 6mm account for a considerable proportion in luxury cruise ships, high-end ro-ro passenger ships, and military ships, and their assembly and welding processes are quite different from conventional ship plates. Due to the structural characteristics of thin plates, it is difficult to control the amount of deformation during processing, and shipowners have high requirements for shipbuilding quality. At present, domestic production mainly relies on high-level workers, which brings a bottleneck to large-scale production. Improve the automation and intelligent production capacity of thin plate processing in shipyards, maximize the saving of construction hours and workers' workload, help promote the speed of intelligentization in ...

AI Technical Summary

Problems solved by technology

The long-distance welding seam of the butt joint of the hull plane plate is very suitable for the production line operation, but the production line of the shipyard cannot be similar to the automobile production line, and the complete flow operation is realized. Different ship types or different parts of the same ship hull have great differences in plate thickness specifications , the shipyard production line needs to adapt to the assembly and welding of steel plates of various thicknesses, and the production line for thin plates must also take into account thick plates, otherwise the production efficiency cannot be fully provided

[0003] Submerged arc welding, MIG or MAG arc welding methods are commonly used for butt welding of steel plates in shipyards in the prior art, which has relatively large input energy, low welding productivity, sensitivity to thick plate defects, difficulty in controlling thin plate deformation, and reduced joint performance. It is difficult to meet the needs of modern shipbuilding in terms of welding quality and speed
