What kind of production process is used to form the GB elbow

Hot push elbow forming process is a process in which the common elbow pushing machine, core die and heating device are used to make the blank on the die move forward under the push of the pushing machine, and it is heated, expanded and bent in the process of motion.Hot push bend deformation characteristics are based on volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter bend diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by hole diameter, wall thickness uniform Angle is obtained.

Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production, so it has become the main forming method of carbon steel and alloy steel elbow, and is also used in the forming of some specifications of stainless steel elbow.

Stamping elbow is the earliest forming process used in mass production of seamless elbow, which has been replaced by hot pushing or other forming processes in the production of elbow of common specifications.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.

Before stamping, the tube billet is placed on the lower die, the inner core and end die are loaded into the tube billet, the upper die moves downward to suppress, and the elbow is formed through the constraint of the outer die and the supporting effect of the inner die.
