We do not bring pipe familiar in everyday life often have access to, use of pipe fittings of a very large extent, reflect the difference in some of our country, in Japan, whether the sample or information on, many types of pipe fittings, the Type all kinds. If you give a definition of the tube, I think that all pipe products after processing, should belong to the scope tube. Since then the tube is a tube made by processing raw materials into a product, therefore, the product has pipe and mechanical parts of the double feature is the combination of the two. Pipe is pipe the raw materials necessary, but a lot of tube processing methods, as long as the mechanical processing method, which can be applied.
Many kinds of pipe fittings, there are several main types of induction:
1. Variable diameter pipe, that pipe ends or possession of a portion of reduced diameter;
2. Variable wall thickness of pipe fittings, refers to the direction along the tube length to thickness changes;
3. Change the section of the tube, on request, the circular section into a square, oval, polygon, etc.;
4. Curved pipe, we contacted more and more, is to become a straight pipe bends of different radius of curvature, such as elbows, bends, etc.;
5. With flange and round edge of the tube, the former refers to the inner tube or outer end of scoliosis, which refers to the direction of the circumference of the pipe form a bulge or recess of the tube;
6. Classes with Juan Bian and back fittings, pipe end to increase the total strength of the outside or the inside of the tube or pipe crimping to seal the tube end;
7. Expanding pipe, pipe fittings as required to end or extend a part of the formation of various shapes of tube;
Tube 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, and the combination of processing methods. Tube processing is the processing of machining and metal combination of pressure.
An example is as follows:
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.
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.
Roller method: place the cores in the tube, with a wheel peripheral push for a round edge processing.
Why pipe so rapidly in overseas development, I think there are two prominent advantages: the first part of the machine instead of processed products, and the ratio of machining parts, casting, forging structural parts, light weight, save material; second, than mechanical saving processes processing products, working hours and lower parts costs.
