A stack welding device for thin-wall stamped sheets

Abstract

The invention relates to the technical field of laser processing, and discloses a stacking welding device for thin-wall stamping sheets. The stacking welding device for thin-wall stamping sheets comprises a transmission assembly, a swing arm air cylinder inner circle pressing assembly, an outer circle rotary supporting assembly and an outer circle pressing and buckling plate assembly. A sheet group is arranged on the transmission assembly and can vertically move under the action of the transmission assembly. The swing arm air cylinder inner circle pressing assembly and the outer circle rotarysupporting assembly are arranged at the upper end of the transmission assembly and used for pressing the inner circle and supporting the outer circle during welding. The outer circle pressing and buckling plate assembly is arranged at the lower end of the transmission assembly and used for pressing and buckling the outer circle of the sheet group during welding. The stacking welding device for thin-wall stamping sheets can realize stacking penetration welding of thin-wall sheets, all the assemblies do not interference with one another and work together, the predicted welding effect can be realized, and the stacking welding device for thin-wall stamping sheets is simple in structure, efficient, reasonable and good in welding effect.

Description

technical field [0001] The invention relates to the technical field of laser welding, and more specifically relates to a stack welding device for thin-wall stamped plates. Background technique [0002] When welding the inner and outer circles of thin-walled stamping plates, it is easier to weld the inner and outer circles of the plates independently, but when welding the inner circle first and then adding the plates to weld the outer circle for stacking and continuous welding, It is difficult to realize the mutual non-interference and non-affection in the structure and process of the inner and outer compression components. Due to the uneven conformal cooling circuit on the surface of the thin-walled stamping sheet, it is more difficult to tightly press and fit the inner and outer circles of the sheet. Only about 9mm of welding width is reserved for the inner and outer circles of the sheet. It is also more difficult to realize the supporting distance, pressing distance, weld...

Problems solved by technology

In addition, due to the thinness of the plates, it is easy to be thermally deformed during the welding process, and it is difficult to effectively control the thermal stress deformation; the stacked welding plates need to have good surface quality, and the upper surface and the back of the plates need to be protected by gas
