Equipment composition for the tank round line welding machine
1. Gantry frame and drive device
The gantry frame and driving device are welded by the shape steel, which not only reduce the weight, but also meets the requirement of machine horizen space and rigidity, the gantry fram connected with the bilateral driving device become the walking body. The drive motor is a low-speed three-phase induction motor,stable motion, no torque ripple and adopts frequency conversion speed regulation ,high bilateral synchronous performance.
2 welding trolley
precision welding trolley, smooth walking on the tank, use the servo motor planetary reducer-driven, to guarantee welding more stable.
3. Welding power
Panasonic KR-500 gas shielded welder, welding current range 15-500A. Free load voltage 86V. Weight 50KG.
4. Wire moving device
Adopt stepper motor control to drive the ball screw to move smoothly and steadily, can adjust the moving speed according to the usage.
5. Control system
Use digital control system and PLC programmable technology to control the the action of all components , achieve automatic welding
6 .welding gap tracking
Automatic gap tracking for Up and down
Operators can adjust the right and left welding position in real time according to the deviation of the welding gap
7. Weld swing
According to the welding process to adjust the swing frequency of welding gun , time, swing, dwell time of edge and other parameters
8, control method
Welding system use the automatic control mode to copy the workpiece , the welding trolley can be on the surface of the workpiece, to uniform linear motion welding along the shape of the workpiece , the workpiece automatically rotate or stop controlled by the signal sent by the sensor, to ensure that the line speed is constant when the workpiece rotation speed changed.
