Gantry welding structural principle 

 H-beam welding seam should be straight, beautiful, welding reasonable, LMH gantry welding machine submerged arc welding position 45 ° boat measures, a complete solution to many problems in the welding area. 

 Mainly by the gantry gantry welding, welding arm and extension units, mechanical tracking device torch, flux handling systems, electronic control systems, and submerged arc welding power supply and other components. Mainly from the gantry to support and promote the various parts to weld the various parts of the role of walking speed, the lower part of the two walking beams, the two AC motor driven by the reducer in the gantry on rail travel. Gantry travel speed adjustable, can be adjusted to the desired frequency welding speed, and it also has a rapid return of function. Two pairs of walking beam close to the rail side of the guide rollers to ensure smooth running, the platform located in the middle rack care. Installation of gantry welding arm and pallet rack, pallet upload more than one set by the wheel close up and down, move around the rail. Through the worm gear reducer - gear rack pair, extension units can be hand-tune the left and right move by motor - worm gear reducer - gear rack vice can be driven welding arm, the next move. Welding torch welding machine tracking device installed in the lower arm, wire feeder mechanical tracking device installed in the torch on the welding nozzle is always aligned with the weld seam and maintain a certain gap. One pair of guide wheel close to the weld on both sides of the workpiece, when the weld around the bend, the guide rollers of the upper cross slide by the elastic spring effect for the left and right direction of adjustment; when welding the upper and lower bending, cross slide guide wheel drive for, under the direction of adjustment; the torch mechanical tracking device to adjust the micro-switch; manual also has a gun left and right to adjust the organization. Flux from the soldering iron treatment systems, recycling machines and other flux components, soldering iron and solder recycling boxes were installed in two welding arm, two flux recovery system on the gantry platform; flux from the soldering iron to flow through the valve to be welding seam, the welding nozzle followed by welding, flux recovery in the nozzle tube back into the recovery of the remaining flux tube, the mesh filter, then the flux through the valve into the bucket, dust inhalation flux recycling machine, large blocks remain in the Recycle Bin to the flux. Electrical control system consists of an electric control box and the box composed of two operations, the control box mounted on the gantry to walk under the beam, the two operating box installed in the central gantry, gantry use them to achieve all the action.
