The technology of medium frequency elbow machine to produce elbow pipe fittings

The heating method of the forming process of the elbow is medium frequency or high frequency induction heating (heating ring can be multi-turn or single turn), flame heating and reflection furnace heating, which heating method is adopted depends on the forming product requirements and the energy situation.Stamping elbow is the earliest forming process used in mass production of seamless elbow, which has been replaced by hot pushing or other forming processes in the production of elbow of common specifications. However, in some specifications of elbow, the amount of production is small, the wall thickness is too thick or too thin.

The product is still in use when there are special requirements.The stamping of the elbow is made of tube billet equal to the outside diameter of the elbow, which is directly pressed into shape in the die by a press.

Elbow machine equipment is the most basic pipe fitting equipment of our company. Elbow machine uses medium frequency induction high temperature to push the elbow. This heating method has strong continuity and fast production efficiency, which is suitable for large-scale elbow production.How to make elbow in plate welding?

Make half of the elbow section with the medium plate and press, then weld the two sections together.This process is generally used to make more than DN700 elbow.Seamless elbow forming adopts the forming technology of extruding the tube billet to the outer die and then shaping the tube billet through the ball inside.But this process is relatively complex, troublesome operation, and the forming quality is not as good as cold push elbow machine, medium frequency elbow machine and other processes, so less used.

Elbow machine is an important machine in the range of pipe fitting machinery.It is composed of the following parts: elbow machine hydraulic system is mainly composed of axial piston pump, gear pump, two position cartridge valve system and lock cylinder, push cylinder, core turning cylinder, core turning auxiliary cylinder, stripping cylinder five cylinders, etc.
