Tank longitudinal weld grinding machine

Workpiece diameter range is 400mm~2800mm, workpiece length: 400~3000mm, workpiece thickness: 6mm,

Workpiece weight: ≤5T

Grinding estimate: The tank longitudinal weld grinding equipment uses a sanding belt and double grinding heads to grind the inside and outside of the longitudinal weld at the same time. Each grinding takes about 4 minutes (taking the longest longitudinal weld as an example)

Grinding steps:

1 Input the workpiece diameter and length, and the servo motor adjusts the roller base and roller spacing;

2 Place the workpiece on the roller, manually control the workpiece to rotate slowly, and adjust the longitudinal weld of the workpiece to the bottom;

3 The equipment column base moves horizontally, and the speed is variable and adjustable, driving the grinding head to process and feed. In the horizontal direction, the upper grinding head is located on the inside of the workpiece, and the lower grinding head is located on the outside of the workpiece. (The horizontal distance between the upper and lower grinding heads and the contact wheel is 400mm, leaving space for heat dissipation)

4 The sanding belt grinding head extends into the workpiece, and the upper and lower grinding heads are controlled by cylinders respectively. The sanding belt fits the workpiece and floats under constant pressure to grind the inner and outer surfaces of the longitudinal weld at the same time. (Grinding head air nozzle for air cooling)
