Elbow push system and methods of several kinds of material selection and bend processing

elbow push system and material selection of

the elbow push system and the selection of materials, in the process of the alloy elbow push system, under normal circumstances wall thickness should not be changed, but if for tool reason, some local wall reduction happens, so generally refer to material, wall thickness to add some allowance, such as the elbow is. Mm wall thickness, generally. Mm around the pipe to prevent the push system error due to the local reduction of thickness. After the good shape, bend diameter, wall thickness size has reached the requirement.

alloy elbow to plastic under thermal state. After the plastic outer diameter to reach the size of the finished product. Wall thickness in the wall thickness of incoming material control. Elbow and pipe wall thickness tolerance is the same, are the plus or minus. %。 Because of some elbow after improper handling, will be distorted, this is not allowed. In addition, after have a haircut is usually large front end diameter, through plastic mould for plastic. Plastic mould is actually a press, want to have a set of mould, two and a half arc, the upper one. Elbow materials used in a broad categories with special electrical, sound, heat, power, chemical, and biological function of new materials, biotechnology, energy technology such as the important foundation of technology and national defense construction materials. Elbow materials used in a broad categories with special electrical, sound, heat, power, chemical, and biological function of new materials, biotechnology, energy technology such as the important foundation of technology and national defense construction materials, but also to reform some traditional industries, such as agriculture, chemical industry, building materials play an important role.

bend of the material is special, in certain areas show different use value, to some extent influence the development of other industries. Production of carbon steel elbow need some special raw material for production of materials, the material must carry on the strict selection and control, to select suitable raw materials, otherwise the production of carbon steel elbow there will be no quality assurance.


pipe bending processing several kinds of methods of

stamping, forging, machining method, the bending method, and the combination of roller is processing volumes of several common way to use most is: pipe fittings processing is machining and metal pressure processing of organic links.

pipe bending processing way introduced:

forging method: use the swaging machine will be washed out the pipe end or a local, make the diameter cut, common forging machine with reverse type, rod type, roller type.

stamping method: on the punch with a tapered core of tube end expanding to the required size and shape.

roller method: placed in the tube core, peripheral with wheeled push, used for circular edge processing.

forming method: there are three kinds of method is relatively common, a method called stretching method, another method called stamping method, and the third is all the more familiar with roller method, a - a roll, two fixed roller, an adjusting roller, adjust the fixed roller spacing, products fitting is crooked. This kind of method used widely, if produce spiral pipe, curvature can be increased.

the above to bend processing technology made a simple introduction.
