What are the machining methods for titanium fittings?

Titanium pipe fittings processing method has a variety of methods, 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 the combination of processing method. Pipe processing is the organic combination of machining and metal pressure processing.
Examples are as follows:
Forging method: with the type of forging machine will be the end of the tube or a part of the punch to stretch, so that the outer diameter is reduced, commonly used type of forging machine has a rotary, rod type, roller type.
Stamping method: in the press with a taper of the core will be expanded to the required size and shape of the tube end.
Roller method: A core is placed inside the tube and the outer circumference is pushed with rollers for rounded edge processing.
Rolling method: Generally no mandrel is used, suitable for the inner rounded edge of thick-walled tubes.

Bending forming method: there are three methods more commonly used, a method called stretching method, another method called stamping method, the third is more familiar with the roller method, there are 3-4 rollers, two fixed rollers, an adjustment roller, adjusting the fixed roller distance, the finished pipe fittings are bent. This method is more widely used, if the production of spiral pipe, the curvature can also be increased.
Drumming method: one is to place rubber inside the tube, above the punch compression, so that the tube protrudes into shape; another method is hydraulic drumming forming, in the middle of the tube filled with liquid, liquid pressure to drum the tube into the desired shape, like our commonly used corrugated pipe production most of the production is used in this way.
