Casting pipe ovality correcting machine group is used for correcting unqualified ductile iron casting pipe.

Functions

Casting pipe ovality correcting machine group is used for correcting unqualified ductile iron casting pipe.

General Situation

1.This equipment mainly consists of lifting mechanism, rotating mechanism and ovality correction mechanism, the former two mechanisms set up and rotate the cast iron pipe in order to inspect different parts of the cast iron pipe; and the ovality correction machine corrects oval pipes through pressure.

2. Two sets of lifting machines are equipped in order to inspect and correct the single side of the cast iron pipe to maximum.

 3.Set 4 pressure springs on the upper V-shape block, get enough contact of the V-shape block and the cast iron pipe in the process of ovality correction, but avoid exceeding part pressure to damage the pipe.

4.Using hydraulic motor to rotate the cast pipe and it is easy to change the speed.

5.Manual control, simple in operation and maintenance.

Process

1.Use the synch conveying mechanism to convey the unqualified cast iron pipe to the V supporting rollers of lifting machine I and lifting machine II.

2.Start the rotary button of the supporting rollers to make the cast iron pipe move towards the ovality correction machine.

3.Start the descending button of the lifting machines to drop the pipe in the middle part of the rotator and the rollers of the front rotary rollers group.

 4.Actuate the rotator to rotate the pipe and find out the direction of unqualified part.

5.Stop rotating and pull the handle of the lifting operating valve of the oil cylinder in the ovality correction machine to descend the indenter of the ovality correction machine to press the pipe and make the pipe reach the standard.

6.Push the handle in reverse direction to raise the indenter and at the same time actuate the lifting machines to hold the pipe moving away from the rotary rollers; start the supporting roller’s rotary button of the lifting machine to restore the pipe to the centering position.

 7.The lifting machine start to descend to put the pipe on the synch conveying mechanism.

8.Start the synch conveying mechanism to convey the pipe to the grinding station and the ovality correction process is finished.
