Problems solved by technology

[0005] The welding grooves of the existing welding process are generally V-shaped and U-shaped grooves, and the grooves are all greater than 40 degrees, and conventional parameters are used. This method has no strict requirements on welding errors. Although it meets the requirements of welding depth, However, welding fluid splashes will be generated during welding, and the operation is unsafe. Pores are also likely to be generated in the weld, which affects the quality. Because of the large groove angle and wide gap to be filled, the horizontal accuracy is difficult to guarantee, and the number of welding times is large. Large amount, time-consuming, material-intensive, affecting welding quality, difficult to apply to high-precision welding operations

Abstract

The invention discloses a method for welding a T-shaped movable beam for a deformed glass machining system. The T-shaped movable beam consists of a longitudinal stepping / servo mechanism longitudinal beam, a rib plate, channel steel, a square pipe, a longitudinal stepping / servo mechanism transverse beam, a bottom plate and a vertical plate, and is characterized in that the rib plate, the channel steel, the square pipe, the bottom plate and the vertical plate are 10-15 millimeters in thickness. Automatic rotary welding equipment is adopted, electric resistance welding and carbon dioxide gas protection dual-gun balanced welding are adopted for welding, the welding way of the electric resistance welding includes point welding and backing welding, and the welding way of the carbon dioxide gas protection dual-gun balanced welding includes transverse welding and flat welding, so that the T-shaped movable beam has the advantages of high welding speed, no air hole in welding lines, small bevel angle, high quality, reliable performance and high mechanical performance of joints, and horizontal accuracies of upper and lower horizontal planes are ensured; and when the deformed glass machining system runs, the T-shaped movable beam has ideal synchronizing performance, is firm and highly rigid in structure, runs more stably, and can bear large-torque grinding without being deformed.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding method for a T-shaped moving beam of a special-shaped glass processing system. [0002] Background technique [0003] At present, the moving beam of special-shaped glass processing equipment on the existing market is driven by two sets of driving mechanisms. When the two sets of driving mechanisms operate at the same time, the synchronization is difficult to control, and the operation stability is poor, which affects the dimensional accuracy of high-grade glass products. [0004] A T-shaped moving beam for special-shaped glass processing system is now designed. The T-shaped moving beam adopts an integral frame structure, which is welded by ribs, channel steel, square tubes, bottom plates, vertical plates, and reference planes. The special-shaped glass processing system During operation, the T-shaped moving beam has ideal synchronous performance, strong and rigid struc...
