And the plane for passing through two cusps is pore throat plane L.
Compared with prior art, advantages of the present invention is as follows：
The hot finished steel pipe of variable stagger-angle provided by the invention revolves expansion machine, is driven, is made to roll by driving mechanism
Obtaining roll can be carried out along its axial reciprocating motion, circumferentially rotating by center axis of its axis and is with a vertical centerline
The swing at center can effectively match with a variety of various sizes of mother tubes to be adjusted to roll, will be existing
The mode of replacement different size roll is changed to the mode of adjustment roll, and tool of production setting up expenses can so be effectively reduced, and drops
Low production cost, while the replacement number of roll can be effectively reduced during carrying out expanding to various sizes of mother tube,
Improve production efficiency.
The foregoing is merely the schematical specific embodiment of the present invention, the range being not intended to limit the invention.It is any
Those skilled in the art, under the premise of not departing from design and the principle of the present invention made equivalent variations with repair
Change, should belong to the scope of protection of the invention.
