There are many kinds of steel pipes. Spiral pipe is one of them. Today, Xiaobian will share with you about its specific classification and the methods of deburring. Don't miss it if you pass by.
Spiral steel pipe can be divided into mobile type, semi fixed type and fixed type according to the working mode.
How to form and clean the internal burr of spiral steel pipe?
The process of removing internal burrs is very difficult. As the special device for internal burr cleaning is located in the steel pipe, the working environment is very poor, invisible and difficult to approach. Due to the influence of strip steel precision, unit equipment precision, forming process and weld shape, it is impossible to ensure the burr removal in continuous welded pipe production line or off-line production line.
There are several ways to remove internal burrs:
Cutting method: this method uses a fixed cutting edge or rotating cutting head to extend it into the pipe to cut burrs.
Rolling method: extend the rolling equipment to the pipe to make the internal burr plastic deformation, so as to reduce the height of the internal burr.
Oxidation method: at the beginning of the welding of anti-corrosion spiral steel pipe, use the exhaust nozzle to spray oxygen on the inner weld, and the residual heat of the weld will accelerate the oxidation and falling off of the inner burr and seal it in the air flow.
Drawing method: when the anti-corrosion spiral steel pipe passes through the die, remove the burr in the steel pipe through the annular blade of the float.
There are two kinds of external deburring devices: one is a planer and the other is two planers. When you stop the machine with a planer and change tools, and remove burrs with two planers, you can also change tools continuously.
