Processing Mode Of Pipe Fittings
- Dec 27, 2017 -

There are many kinds of processing method of pipe fittings, many also belongs to the category of manufactured machinery, with many stamping method, forging method, roller processing method, rolling method, bulging method, tensile test, bending method, and the combination of processing method. Tube processing is an organic combination of machining and metal pressure processing. To illustrate as follows: forging method: type forging machine will be at the end of the pipe or part shall be rushed out, the diameter reduced, commonly used swaging machine have rotary, connecting rod type, roller type. Stamping method: with a taper core on the punch press the end of the tube to the required size and shape. Roller method: the core is placed in the tube, and the outer circle is pushed and pressed with the roller for machining round edge. Rolling method: generally without mandrel, suitable for thick wall pipe inside round edge. 

Bending forming method: there are three kinds of methods are commonly used, a method called stretch method, another method called stamping method, the third is more familiar with roller method, 3 - 4 and two, a fixed roller, a roller adjustment, adjust the fixed roller distance, the finished product is bent pipe. This method is widely used, if the spiral tube is produced, the curvature can also be increased. Method: a bulge is placed in the rubber tube, punch the compression above the tube bulge forming; another method is hydraulic bulging in the middle pipe, filling liquid, * liquid pressure into the pipe drum into the required shape, like the production department we used bellows is divided by this method
