5-Axis CNC-Controlled Hydraulic Cylinder Welding System
5-axis CNC system is adopted, which controls the 5-dimension action of rotating, welding torch up and down, forward and backward, left and right, by angle. The spindle revolving speed changes along with the workpiece rotating position, to keep thewelding line speed uniform.
Description
Main features
- MAG air-cooled welding torch is fixed while workpiece is rotating, welding position is horizontal.
- Adopt welded machine body, welding torch and pneumatic tail-stock can be adjusted longitudinally, it can be locked after adjustment.
- Workpiece is positioned by special fixture and pressed by pneumatic thimble. Rotating synchronously. Loading and unloading bracket are mounted under the workpiece.
- Japan OMRON PLC controls the whole machine operation. Workpiece rotation speed is adjusted by inverter, stepless adjustment, to improve the reliability.
- Japan OTC welding power source which has good performance of arc igniting, arc stabilizing and arc ending, to ensure that the welding seam is even and uniform.
- Welding current and welding voltage are controlled by D/A (digital analog). They can be preset and recalled in layer. To realize multi layer continuous welding when the arc does not stop.
- With good appearance and good quality, depth and width of fusion meet the requirement.
- Machine has good operating performance and low failure rate.
Welding oscillating mechanism is used to weld wide and multi layer seams of hydraulic cylinder.

Work process
Manual loading→clamp workpiece→pneumatically press workpiece→ pneumatically feed the welding torch to the welding position→ supply CO2 gas→arc igniting →welding→reach the set welding length,
welding torch oscillates and welds multi-layer, till finish welding →arc ending→stop CO2 gas → welding torch return quickly to origin→ release workpiece → manual unloading
