Automation Welding System for Hydraulic Cylinder, Hydraulic Cylinder Flange Automatic Welding Machine
I. Machine Instruction
Workpiece Loading & Unloading Method: Manual
Locating Method of The Workpiece: Self-centering chuck in the left clamp the workpiece to locate the center of rotation by manual. Two supporting racks locate the center of the workpiece and rotate together with the workpiece coaxially. Pneumatic tailstock is equipped in the right end, the centre of the tailstock sustain the workpiece gyration.
Methods For Welding: Single torch gas shielded arc welding, automatic single-layer welding or multi-layer welding can be achieved once. Single-layer & single-pass welding, multi-layer & single-pass welding, multi-layer & multi-pass welding can be achieved full automatically.
The one end of the workpiece must be clamped and another end has an inner bore. The outer diameter can be supported by the contact rollers to locate the centre of the workpiece. (can weld workpiece while only the chuck clamp it directly or the chuck clamp it and the tailstock press it or the chuck clamp it and the contact rollers support it)
