Automatically complete welding two circular seams of axle head. To make sure that welding specification is even and uniform. With uniform surface and good appearance. Easy and reliable to be used. Welding quality meets welding requirement, quick and convenient to load and clamp.
Axle Welding Machine video:
The machine is composed of main frame, rotation axis box, tailstock and pressing mechanism, workpiece support mechanism, welding torch feeding and adjustment mechanism, electric control system, pneumatic system and welding power source.
3.1 Main frame
3.2 Rotation Axis Box
Rotation head consists of AC frequency motor, reducer, fixture and conductive sleeve, etc. The rotation speed is regulated by controlling inverter to adjust motor speed. Reducer with two-grade worm and gear, aluminum shell, with high output torque, easy installation and maintenance. Conductive sleeve adopts copper sleeve. Conductive oil is poured between copper sleeve and rotation axis, abrasion resistant and good electrical conductivity.
3.3 Tailstock Clamping Mechanism
Pneumatic tailstock is adjustable along the guide rail, to meet the welding requirements of different varieties. Pneumatic tailstock adopts manual screw adjustment. The workpiece is tightened by pneumatic thimble and rotates with it.
3.4 Torch Clamping&Adjustment&Pneumatic Lifting Mechanism
3.5 Electric Control System
3.6 Pneumatic System
It consists of solenoid valve, air cylinder, oil-water separator and cables, etc. To control workpiece clamping, welding torch up and down and other actions. Pneumatic components use famous brand products.
3.7 Welding Power Source
Japan OTC CPVE-500 (rated output current is 500A) welding power source. Its arc is stable, which controls heat input for good penetration and reduced spatter and smoke. 1 set power source will go with your machine.
Push-type wire feeder(OTC) is installed at the moving arm of the torch holder for short distance wire feeding and give stable feeding.Machine is with high welding voltage and slow wire feeding performance, which guarantees reliable arc igniting. Machine is also with low welding voltage and low welding current for filling crater.
Manual loading→hold and clamp the workpiece→falling down the welding torch→supply CO2 shielding gas—→high voltage, slow wire feeding for arc igniting→detect welding current signal→rotate workpiece, weld the bottom weld→reach set welding length→welding torch automatically lifts and oscillates →reach set welding length→small current, low-voltage for arc ending→stop CO2 shielding gas→ welding torch returns→ open sliding door→ unload the workpiece
