H beam assembling welding and straightening integral machine

Assembling welding and straightening integral machine is a special machine which can make direct assembling, welding, and straightening for the H-beam flange and web plate. It combines the working procedures of assembling machine, gantry welding machine, and straightening machine into one machine, which makes visible higher production efficiency, lower machine cost, and smaller space. Thus it is a high-efficient machine for H-beam and T-beam production.

This equipment is composed by assembling and welding main machine, assistant straightening machine, pre-centering system, driving elevating roller conveyor, driving roller conveyor, idle roller conveyor, flux recycling system, hydraulic system, electrical controlling system, and welding power source etc.

The assembling and welding main machine is composed by bottom stand, up frame, flange and web plate centering system, main transmission device, welding torch adjusting device, and conduction device etc.

The bottom stand is welding construction, on which there is flange and web plate centering device, main transmission roller, welding torch adjusting system, conduction device and up frame. On down part of the bottom stand, there is transmission axis, and chain wheel, chain of the main transmission system. The main transmission motor speed-reducer is assembled at the side of the machine bottom stand.

On the up frame, there is assembled with up pressing roller. The up pressing roller is fixed on the elevating beam of the up frame, the elevating beam can make up and down elevating movement on the rail of the up frame, which is driven by up pressing cylinder.

The flange and web plate centering device is driven by hydraulic motor, the pinch roller centering and pinching the flange and web plate is driven by worm speed-reducer, gear transmission, screw rod lead screw

The main transmission is of motor speed reducer driven, the main transmission roller rotation is driven by chain transmission, meanwhile the chain from main machine drive the main straightening roller of the assistant straightening machine rotating at the same speed. The assembling and welding speed adopts AC frequent speed adjusting, which can be adjusted in the range of 0.35-3m/min.

The machine web and flange plate orientation, centering, pinch and up pressing roller pinch is driven by hydraulic system. The action pressure can be adjusted by the pressure adjusting valve of the hydraulic station.

Assistant straightening machine is composed by up straightening roller system, down straightening roller system, flange centering device etc. The two up straightening roller is driven by hydraulic cylinder, and can press down the flange. One down straightening roller is driven by chain of the main machine which can make continuous straightening of the workpiece.

Pre-centering device is used for making primary centering for the flange and web plate that fed into the roller conveyor. The flange and web plate two centering system action is driven separately by the two hydraulic cylinders.

The driving elevating roller conveyor has the function of elevating, and also the supporting of the welded and deformed workpiece.

The flux recycling system can send the flax to the welding seam, and recycle the remained flux after welding, which make a circular system of the flux feeding and recycling.
