subject: Pipe Fittings Processing Methods [print this page] pipe fittings processing methods there are many. Many also belong to the class machining area is the most used punch method, forging method, roller processing method, rolling method, bulging method, stretching,
Bending method, and the combination of processing methods. pipe fittings and metal machining process is the combination of pressure processing.
An example is as follows:
Stamping method: In the red bed with a tube with a taper of the cores will be extended to the end of the size and shape requirements.
Forging Method: The type forging machine or part of the tube ends to be washed and puts a diameter less common type forging machine with rotary type, link type, roller type.
Roller method: place the cores in the tube, with a wheel peripheral push for a round edge processing.
Rolling method: general do not spindle, suitable for thick-walled tube inside a round edge.
Bending method: There are three methods more commonly used method called the extended method, another method called stamping method, the third is all the more familiar roller method, a 3-4 roll, two fixed roller, a
Months to adjust roll, roll to adjust the fixed distance, finished pipe fittings is bent. Wider application of this method, if the production of spiral, the curvature can be increased.
Bulging method: one is placed in the tube of rubber, with a punch at the top of compression, so that bulge forming tube; Another approach is hydraulic bulge forming, the central tube filled in the liquid, the liquid pressure to drum into the tube
The required shape, as we often bellows is used in the production of most of this method.
In short pipe fittings are widely used variety. Japanese production methods are authorized, and some pipe fittings production methods and processes to declare the patent, pipe fittings patent is
Many, mostly combined processing. Our pipe fittings processing disparities, for example: Three four-way bicycle use in foreign countries as early as 2045 on the head with bulging shape of the tube, while the factory in China
Home to the present method may also welded. It almost did not recognize such things, it is difficult to accept new things, if any, manufacturers are not necessarily willing to change this process. This side in pipe fittings in China
