The secondary mould of shape；
The main mould is connected with turn in a rectangular parallelepiped shape for bending steel pipe close to the side of the secondary mould towards main mould sliding
Mould；
The side wall of main mould, secondary mould and revolving die is in the cambered surface with steel pipe cooperation and is respectively connected with respectively its three offer power
Force piece；
Secondary mould and revolving die slide towards main mould and by steel pipe clampings, and revolving die is around master while subsequent main mould is along own axis
Mould is axis rotation, makes steel pipe bending；
The other end of the body is detachably installed with fixing pipe, in fixing pipe and stretch to revolving die direction be detachably installed with it is soft
Bar.
By using above-mentioned technical proposal, steel pipe is placed in binding clasp and is clamped, and the end of steel pipe is made to be placed on master
At mould position, soft bar is fixedly arranged in fixing pipe and is plugged in steel duct, soft pipe is enable to fill the inside of steel pipe
Full, then secondary mould is pushed to and rotates revolving die with steel pipe cooperation position, unlatching master cylinder, make the end of steel pipe by starting clamping cylinder
Portion is bent under the limit and promotion of revolving die, since steel duct is plugged with the soft bar full of steel pipe, so steel pipe
Side wall is difficult to be recessed inwardly under the extruding of revolving die and secondary mould, reduces the generation of defect.
Preferable: the soft bar includes being threadedly connected in fixing pipe and capable of extending to made of the rubber at main mould to protect
Guard bar.
Possess reversible deformation, so in steel pipe quilt since guard bar is rubber material by using above-mentioned technical proposal
