304 Stainless Steel 4-Point Three-Way Elbow To Internal And External Wire Water Pipe Joint Direct Through DN15 Connector
Hot push elbow forming process is the use of special elbow push
machine, core die and heating device, so that the billet set on the
mold in the push of the machine to move forward, in the movement of
heating, expanding and bending forming process. 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,
suitable for mass production, so it has become the main forming
method of carbon steel, alloy steel elbow, and also used in the
forming of some specifications of stainless steel elbow.
The heating method of forming process has medium frequency or high
frequency induction heating (heating ring can be multiple or single
ring), flame heating and reflector heating, which heating method
depends on the requirements of forming products and energy
conditions.
