H-beam Gantry Welding

Features of H-beam Gantry Welding

Developed based on the particularity of H-beam ship-shaped welding and combined with years of technical experience in developing welding equipment, it is mainly composed of gantry, slide mechanism, welding gun mechanical tracking device, flux recovery system, pneumatic system, electrical control system and submerged arc welding machine.

The gantry is the skeleton of the machine. Its rigidity and strength have been calculated in detail and the design is reasonable. The main parts are stress-relieved after welding, and the operation is long and has a long service life. The walking mechanism is driven by two AC motors through frequency conversion control to achieve bilateral synchronous drive. The side of the rail is equipped with a wheel mechanism to ensure the smooth and safe operation of the gantry.

The welding head can be operated up and down and left and right smoothly through multiple sets of adjustable eccentric wheels and rectangular guide rails. The left and right movement of the slide and the up and down movement of the welding arm are all equipped with motor reducers and gear rack mechanisms to adapt to the welding of steel sections of different specifications, and avoid the phenomenon of not being able to stop positioning in the middle of the cylinder transmission, ensuring smooth and reliable operation.

Equipped with an H-beam arc guide frame, H-beam ship-shaped welding can be performed. The arc guide frame adopts three-axis mechanical tracking. The up and down tracking uses pneumatic and welding arm self-weight guide wheels to press the workpiece. The left and right rotation is floating tracking. It also has a welding gun fine-tuning mechanism to ensure the accurate position of the welding gun and avoid the welding deviation phenomenon of conventional products.
