Three modules of operation principle point for being used to bend the bending machine of oil pipe are illustrated.
The operation principle of stretch bending module is：Oil pipe fixture is clipped admittedly and so that oil pipe needs the duct section of bending to be located at
Between the stretch bending roller of stretch bending module and the first benchmark roller, under original state, stretch bending roller externally protrudes out in the first benchmark roller, draws
Contracting driving cylinder action so that the piston rod of pulling-down driving cylinder is retracted, drives stretch bending roller to retract so as to drive duct section to inside contract, and
First benchmark roller props up that duct section is motionless, and then realizes the bending of duct section.
The operation principle of bending module is：Oil pipe fixture is clipped admittedly and so that oil pipe needs the duct section of bending to be located at
Between the bending roller of bending module and the second benchmark roller, under original state, the second benchmark roller externally protrudes out in bending roller,
That is, bending roller most the inside near ejection driving cylinder position, oil pipe is located at middle and the second benchmark roller most
Outside, ejects driving cylinder action so that the piston rod ejection of ejection driving cylinder, drives bending roller outwards to eject oil pipe, and the
Two benchmark rollers prop up that oil pipe is motionless, and then realize the bending of the duct section of oil pipe.
Twist and warping module operation principle be：Oil pipe fixture is clipped admittedly and so that oil pipe needs the duct section of bending to be located at
Between the twist and warping roller and the 3rd benchmark roller of twist and warping module, the piston rod for driving twist and warping driving cylinder rises, and promotes cylinder rotation
Core rises and rotates, and then drives square shaft to rotate, then drives main axis so that twist and warping roller is public around the 3rd benchmark roller
Turn, the oil pipe bending being most clipped at last between two rollers.And, the ascensional range of mechanism's energy precise control cylinder, and then
Precise control twists and warps revolution angle of the roller around the 3rd benchmark roller, the bending angle and dynamics of final precise control oil pipe.
And, the bending angle for twisting and warping module to oil pipe is maximum.
After above structure, the present invention for bending the bending machine of oil pipe compared with prior art, with advantages below：
