Detail

The thickness of the guide ring is the main factor that determines the size of the opening angle of the high frequency welded pipe machine. The thickness of the guide ring of the commonly used unit is shown in the table below.

 

High frequency welded pipe machine

 

The main basis for the determination of the guide ring is to ensure that the welding opening angle of the high frequency welded pipe machine is between 2°and 6°, and the thickness of the new guide ring corresponds to about 6°. With the occurrence of wear, the opening angle gradually becomes smaller; when the thickness After the wear exceeds 1/2 of its wear, you should consider replacing the guide ring.

 

The bevel angle of the guide ring is related to the width of the tube blank, the forming allowance, and the thickness of the guide ring. See formula:

The addition of 2°to 5°in brackets is to ensure that the guide ring is in contact with the outer edge of the forming tube first, so as not to damage the inner edge of the tube blank.

 

The ideal contact state between the guide ring and the tube blank should be that the thickness of the tube blank just fits the slope of the guide ring. When the ideal contact state cannot be achieved in actual operation, the inner edge of the tube blank should be avoided to ensure that the guide ring is in contact with the outer edge of the forming tube.

If the guide ring contacts the inner circle edge of the forming tube earlier, it will accelerate the wear of the guide ring and crush the inner circle edge of the tube blank.

 

Outer diameter of guide ring:

The outer diameter of the guide ring is too small, and the ring is easy to roll to the edge of the tube blank, causing the edge of the formed tube blank to be curled;

If the outer diameter of the guide ring is too large, it is difficult to penetrate the magnetic rod, and it is not economical.

The thin-walled tube takes the larger value.

Thick-walled pipes take the smaller value.

 

The above is to determine the main dimensions of the guide ring of the high frequency welded pipe machine, and also to ensure the quality of the welded pipe forming and weld repair quality when the high frequency welded pipe machine produces welded pipes, so as to produce standard welded pipes.
