Information

There are many processing methods of pipe fittings, many also belong to the category of mechanical processing, the most used is the stamping method, forging method, roller processing method, rolling method, bulging method, stretching method, bending method, and combined processing method.

Pipe fitting machining is an organic combination of machining and metal pressure machining. Examples are given as follows: forging press: with the end of the pipe or part of the punching machine to reduce the outside diameter, the common type forging machine has rotary, connecting rod, roller type. Punching: Tube ends are expanded to the desired size and shape with taper cores on a punch press. Roller method: the core is placed in the tube, and the circumference is pushed by the roller for the round edge processing. Rolling method: generally do not use mandrel, suitable for thick wall tube inside round edge. Bending forming method: there are three methods more commonly used, one method is called stretching method, another method is called stamping method, the third is the more familiar roller method, there are 3-4 rollers, two fixed rollers, an adjustment roller, adjust the fixed roller distance, the finished pipe fitting is bending. This method is widely used. If spiral tube is produced, the curvature can be increased. Swelling method: one is to place rubber in the tube, the upper part of the punch compression, so that the tube protruding shape;Another method is hydraulic bulging, in which a liquid is filled in the middle of the pipe. * Liquid pressure is used to blow the pipe into the desired shape. This method is used for most of the production of bellows like the ones we commonly use.
