Elbow machine

Elbow production and manufacturing process, elbow is used for pipe turning a pipe fitting, there are 90 degree elbow, 45 degree elbow, etc., can be produced according to the needs of the project, different materials and different pressure of the elbow production and manufacturing process is different.

Heat push elbow is a process adopted in the production and manufacture of seamless elbow. Elbow push machine, mandrel and heating device are adopted. The blank on the mold is pushed forward by elbow push machine, and the process of heating and expanding and bending is carried out in the operation of pipe.The deformation characteristics of the hot push elbow are to determine the diameter of the pipe according to the law of constant volume before and after the deformation of the metal material. When the pipe is used, the diameter of the pipe is smaller than the diameter of the elbow. In the heating deformation of the elbow, the diameter of the pipe is compensated to the due to the expansion

While thinning other parts, so get a uniform wall thickness of the elbow, this is pushing the elbow manufacturing process.Elbow push system machine push out of the elbow, beautiful appearance, uniform wall thickness can be continuous production and manufacturing, mass production can elbow push system, so the general carbon steel elbow, alloy steel elbow push system adopted by the main technology of manufacture is production and manufacturing, and also used in some of the specifications of the stainless steel elbow forming (thermoforming machine advantages of elbow push system)

The hot push elbow machine is to place the pre-cut pipe section on the head of the horn core and heat it to the austenite zone. Through the thrust applied at the back of the pipe section, the pipe section receives eccentric expansion and bending deformation, and is processed into an elbow with enlarged diameter and unchanged wall thickness.Flame heating, the temperature of the billet in setting is also high, generally above 70 ° c, so you need to setting long some other deformation occurring in order to prevent the elbow for mandrel itself, in the process of pushing bending, mandrel in heating furnace in paragraphs are high temperature, and the pipe resistance to deformation of the gravitational pull on the mandrel, mandrel to work long hours under high temperature stress have been straight or the possibility of brittle fracture, so using the intermediate frequency induction heating.Elbow pushing machine itself belongs to non-standard products, so there is no specific specifications and models, we can directly customize according to customer requirements

We can make elbow diameter from 21mm to 1620mm and wall thickness from 3mm to 120mm

Elbow machine is mainly used for bending carbon steel and alloy steel. If you need stainless steel elbow, please choose cold push elbow
