Abstract

The invention discloses a stainless steel vehicle corrugated plate automatic seam welding welding device and welding method, which comprises a central axis support frame, one side of the central axis support frame has welding equipment; The supporting mechanism is separated by a fixed plane structure between adjacent rolling supporting mechanisms; the rolling supporting mechanism and the fixed plane structure jointly support the corrugated plate; the device also includes: a guiding and pressing mechanism integrated in the welding equipment ; The guiding and pressing mechanism compresses the corrugated plate and limits the displacement of the corrugated plate. The device and method of the present invention solve the welding problem of automatic seam welding of 0.6mm thin plates, and at the same time, no reinforcement is generated in the weld seam; the production efficiency is improved through the device and method, and it only takes 7 minutes to weld the weld seam of a 10m long corrugated plate , The production efficiency is more than 3 times higher than that of the original carbon steel MIG arc welding, and there is no smoke and dust, realizing green production.

Description

technical field [0001] The invention relates to the technical field of processing stainless steel vehicle corrugated plates, in particular to an automatic seam welding welding device and welding method for stainless steel vehicle corrugated plates. Background technique [0002] At this stage, the demand for lightweight stainless steel vehicles is increasing. The underframe corrugated plate is made of three austenitic high-strength thin-plate stainless steels with a width of about 0.7m~1m, a length of about 10m~12m, and a thickness of 0.6mm or 0.8mm. Material lap welding is complete. see figure 1 as shown, figure 1 A schematic diagram of a stainless steel corrugated plate welded structure in the prior art is shown. Wherein, the corrugated plate of the chassis includes three thin plates, which are respectively the first corrugated plate, the second corrugated plate and the third corrugated plate, the first corrugated plate is lapped on the second corrugated plate, and the s...
