Filed pipe fittings of us are intimately familiar with in their daily lives often have access to, pipe fittings use a very large extent, reflect the difference in some of our country, in Japan, regardless of
Samples or data is introduced, pipe fittings are many kinds of variety. If you give a definition of pipe fittings, I think that all pipe products after processing, should belong to pipe
fittings category. Japan did so. Since then the pipe fittings are made of raw materials through processing tube into a product, so the product has pipe and mechanical parts of the double feature
Is a combination of the two. Pipe fittings pipe is necessary for raw materials, processing methods, but a lot of pipe fittings, as long as the mechanical processing methods, which can be applied to. pipe fittings for the
What is the development in foreign countries so rapidly, I think there are two prominent advantages: the first part of the machine instead of processed products, and more than machining parts, casting, forging structural parts, light weight, save material;
Second, save more than mechanical processes processing products, working hours, lower parts costs. Japanese materials industry information on a kind of truck used method of connecting rod machining method and pipe fittings done more, the same production
Product weight with the weight of the different materials, machining method is 10.35kg, and to do this part with the pipe fittings are used 9.32kg, saving materials; machining of parts is priced at 240 yen, if
Use of pipe fittings is priced at 140 yen. So, pipe fittings have the edge in price, nearly 50% lower. From a performance sense, pipe fittings law is superior to mechanical processing method.
many kinds of pipe fittings, there are several main types of induction:
1. Variable diameter pipe fittings, pipe end or pipe that a part 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 pipe fittings, upon request, the circular section into a square, oval, polygon, etc.;
4. Curved pipe fittings, we have come more and more, is to straight pipe into different radius of curvature of the bend, such as elbows, bends, etc.;
5. With flange and the circular edge of the pipe fittings, the former refers to the inside pipe end or outside scoliosis, which refers to the direction of the circumference of the pipe form a bulge or recess of the pipe fittings;
6. With crimping and back like pipe fittings, pipe end to increase the total strength of the outside or the inside of the tube or pipe fittings crimp sealed end of the pipe fittings;
7. Expanding pipe fittings, pipe fittings as required will end or extend a part of the formation of various forms of pipe fittings;
pipe fittings processing methods there are many. Many also belong to the class machining area, the most used method is stamping, 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:
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 on the 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.
