Manufacturing method of super-large thick plate cross box member

Abstract

The invention provides a method for making a super-large thick plate cross box-shaped member, which is used to make a roll-over mold and a welding-resistant deformation mold; first, the inner web and wing plate of the cross box are assembled, and then fixed to form a well-shaped member; The front end and rear end of the component are respectively fixed with a rolling mold; the anti-welding deformation mold is inserted into the outer notch of the cross box wing plate, and the anti-welding deformation mold supports the notch; the CO2 gas shielded welding automatic trolley with small heat input is used to align the inner belly The plate welds are symmetrically welded, and the position of the construction welds is adjusted by rotating the tumbling mold; the outer webs of the cross-shaped box are assembled and welded; after the overall welding of the cross-shaped box is completed, after the components are slowly cooled to room temperature, The anti-deformation mold is disassembled, and the invention adopts a special hoisting and rolling mold, which reduces the use of cranes, saves time, and improves work efficiency; better controls the deformation in the process of processing and the dimensional accuracy of assembly, so that The production process is more standardized and simplified, the cost is lower, and the precision is more accurate.

Description

Technical field [0001] The invention belongs to the construction structure construction technique, and specifically, the method of fabricating a super large thick plate type member. Background technique [0002] In the ultra-large thick plate type cross box type structure, it is combined by two groove type and one microphone box. Because of its monomer groove type and merit shape, it is more deformed during welding, and it is difficult to Control, the subsequent repair amount is also large, and directly affects the assembly quality of the components. Such ultra-large thick plate cross box types are special, and there is no special spreader, and the lifting is extremely inconvenient, affecting the production efficiency of the components, and there is a large safety hazard. [0003] In the process of making a super large thick plate type structure, there is the following defects: 1) The prior art is to directly process two monomer groove types and one microphone type, and then comb...
