Axle Head CO2 Automatic Welding Machine
I.Design mission
Complete the automatic welding of two circular seams in the joint between axle head and axle housing. To make sure that welding specification is even and uniform. With uniform surface and good appearance. Easy and reliable to use, welding quality meets welding requirement, quick and convenient to load and clamp.
II.Basic Conception
Welding torch is fixed, while the workpiece is rotating. Welding position is horizontal. The two ends of axle are pressed pneumatically and rotate together.
Using double water-cooling torches and two power sources to reduce the welding deformation.
The machine has high voltage and slow wire feeding performance, which guarantees reliable arc igniting. Machine also has low welding voltage and low current for filling crater.
The welding torch must have oscillating and synchronous lifting functions to realize the automatic lifting and oscillating of the welding torch during the welding process to complete the multilayer welding and fill up the welding pass.
The welding current, voltage and welding speed of each layer in each welding parameter, the welding torch oscillating frequency, oscillating scope, oscillating time, welding torch automatic lifting time, lifting distance and lifting frequency can be preset and recalled in steps. 100 sets of welding parameters can be pre-stored.
Welding torch, rotation axis box and tailstock can be adjusted longitudinally, to meet different types welding.
Using PLC to control the whole machine operating, AC frequency speed regulator, to improve the reliability of equipment.
Adopts axis central hole position and pneumatic pressed mode.
Using the man-machine interface to modify parameter.
