Common production process of elbow

Common production process of elbow

Elbow is used in the pipe bend a pipe, in the pipeline system used by all the pieces, accounts for the largest share, of different material or wall thickness of the elbow to select different forming technology, the most common is hot forming elbow machine.
Hot forming is a dedicated elbow push system movement mode and heating device, make on the mould of billet in pushing forward movement, under the impetus of the machine in motion is heated hole enlargement and 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.
Elbow hot forming  process with good appearance even wall thickness and continuous operation, suitable for the characteristics of mass production, thus become the main forming methods of carbon steel alloy steel elbow, and also the application in some of the specifications of the stainless steel elbow forming.
