Description

Technical Field

[0001] This utility model relates to the field of ultra-thick wall tube flaring technology, and in particular to a large-diameter ultra-thick wall tube flaring cooling device. Background Technology

[0002] Flaring and cooling of ultra-thick-walled pipes is a process that uses mechanical transmission and flame heating to flare ultra-thick-walled pipes, increasing the diameter of the billet end. The billet enters the deformation zone under axial force, where it undergoes tangential tensile flaring plastic deformation. It then enters the stable deformation zone, finally forming the pipe. The flaring shape can be conical or cylindrical. Some shorter ultra-thick connecting pipes are used for pipe connections after flaring. After heating and flaring, the pipes need to be cooled.

The material tray is then placed in the cooling pool... Next, the limiting frame is inserted through the fixing frame and plugged into the connecting seat. Then, the limiting frame and the connecting seat are connected and fixed with the second bolt and nut. This can play a guiding and limiting role when lifting the material tray. Then, the limiting plate is sleeved on the outside of the third bolt and then threadedly connected to the protrusion. The bottom of the limiting plate is attached to the top of the connecting frame to prevent the limiting plate from rotating, thereby fixing the limiting plate. The outer side of the end of the limiting plate is attached to one end of the second bolt to prevent the second bolt from falling off.
