2.Description

This machine used to weld round conical pole and polygon prism pole. It also suitable for equal diameter pipe’s welding.

This machine adopt workpiece moving and welding gun fixing. When welding, vertical pressurized cylinder and lateral pressure cylinder change synchronization pressurized according to the workpieces. Keep sure the position of the welding gun and gaps of welding unchanged.

This machine combined by mechanical system, hydraulic system, welding system and control system and so on. Mechanical system include gantry frame, welding wrong side control mechanism,welding institutions,seam institutions,water-cooled cooper pads,workpiece running trolley and track,lifting rotation roller and so on.

1,Mechanical System

1.1,Gantry body

Gantry body is host skeleton, installed lifting beams,it can be move up and down and suitable for welding different diameters.

Floating beams mounted on the workpiece positioning mechanism, welding wrong side control agencies, welding head ,cooling water tank and so on.

1.2,Welding wrong side control mechanism

Seam device complete by cylinder drive pressure wheels. Upper pressure wheels adjust the workpieces with wrong sides. Pressing ensure the welding smooth and prevent trail to be wrong.

1.3,Welding institutions

In the upper pressure wheels there is one group of welding correcting leading wheel, make sure the welding to be at the 12 o’clock position and welding running well. Leading device has leading blades which made of resistant materials, it can provide the best guiding and make the welding and welding gun centralized. Keep in the same line.

1.4,Seam institutions

Seam institution has two groups of side pressure units, upper pressure wheels workpieces positioning. Pressure from four directions combined longitudinal seam closing. At the same time, control longitudinal seam unfitness. All pressure wheels assembly is driven by hydraulic system pressure adjustable seaming. Side pressure head device has two cylinders and pressure head institutions. The angle of the pressure head can be adjusted.

Seam institutions make the workpieces closed, all the pressure points are roller wheels institutions and reduce the friction of the workpieces.

1.5,Water-cooled copper pads

To avoid melting when during the submerged arc welding process, we design the water-cooled copper pads, ensure the welding is deep and forming penetration. Welding forming pads were driven by gas cylinder.

1.6,Workpieces running trolley

Trolley driven by frequency conversion motor, via the reducer, gear, rack moving with workpieces. Trolley has quick empty return. On trolley there installed workpieces positioning block to prevent workpieces horizontal scrolling. Trolley speed can be adjusted.

1.7,Lifting rotating roller

Lifting rotating roller(welding assist in device)installed on the trolley. Lifting rotating roller drive workpiece rotate smoothly into the center of the welding. Convenient to be automatic seam welding state.;when the workpieces combined by many sheets, it needs change position of welding.

1.8,Circulating water cooling system

Circulating water cooling system used to cool the copper pads device.

2,Welding System

Welding system includes u.s. lincoln dc-1000,ac-1200 welding source,with na-3control casing,na-4control casing,na-3s wire feeder,welding cable, and flux transported recovery device and so on.

Welding system select dual power.

Flux recovery machine recover the flux after submerged arc welding.

Flux recovery system is composed of collector, storage barrel, small funnel, nozzle, dust and impurities collection boxes. Welding flux. Use pressure conveyor and gravity discharge. Flux recovery use vacuum recovery.

3,Hydraulic System

This hydraulic system pump station combined by fuel tank, double pump motors and hydraulic components and so on. Hydraulic components has direction change valve, relief valve, proportional relief valve, check valve, pilot operated check valve and other components. The system has a selection of high quality hydraulic ,accessories , comply with the technical requirements of gb3766-87 general technical conditions of the hydraulic system.

This hydraulic system adopt fully enclosed tank structure. Allow work in harsh environments with large dust. But it should pay attention to regular cleaning dust on hydraulic equipments and ensure that the hydraulic system has good heat dissipation.

4,Control System

Control system use plc as the main control unit. Adjustment button on the control box can achieve welding speed, technical parameters’ adjusting and welding head position.
