Processing methods of pipe fittings there are many. Many also belong to the scope of machining and the like, the most widely used method of stamping, forging method, roller processing method, rolling method, bulging France, stretching, bending method, and a combination of processing method. Tube processing is machining and metal pressure processing of organic combination.




Follows is an example:
Forging method: with swaging machine pipe ends or part be reversed extension, Neptune Casino outer diameter less common rotary swaging machine has, link type, roller.
Stamping method: In the punch core with a tapered end of the tube to expand to the required size and shape.
Roller method: placed in the core of the inner tube, with the outer periphery of the roller pushing for round edge processing.
Rolling method: generally do not have the mandrel, suitable for thick-walled tube the inside edge of the circle.
Bending method: There are three methods more commonly used, a method called stretching method, another method called stamping method, and the third is more familiar roller method, 3-4 rollers and two fixed rollers, an adjustment roll, roll gap adjustment fixed, finished tube is curved. Broader application of this method, if the production of spiral, the curvature also increases.
Bulging method: one is placed in a rubber tube, with the upper punch compression, the tube bulge forming; Another method is hydraulic bulge forming, in the middle of the tube filled with liquid, the shape of the tube by liquid pressure drum to the desired like we used bellows production of most of the use of this method.
