Detailed description of the invention
The cold rolling pipe expander of liner, including head end lid, end cap, center-pole.Center-pole is through head end lid and end cap
Centre bore.The outside of head end lid is provided with clamp nut, and center-pole is threadeded with clamp nut, clamp nut and head end lid it
Between be provided with thrust ball bearing.It is provided with inner press roll on center-pole between head end lid and end cap.On head end lid circumference uniform
Having shifting chute, end cap is provided circumferentially about shifting chute.Shifting chute on head end lid and the shifting chute on head end lid are correspondingly arranged.
Between shifting chute on head end lid and the shifting chute on head end lid, external compression bar is set.Outer pressure roller it is provided with in external compression bar.Inner press roll,
Outer pressure roller is round table-like.The face area of inner press roll end cap side is more than the face area of inner press roll head end lid side, external pressure
The face area of roller end cap side is less than the face area of outer pressure roller head end lid side.
Arranging interior runner between clamp nut and thrust ball bearing, interior rotaring wheeling sleeve, on center-pole, head end lid is fixed and is set
Being equipped with the first rotating shaft and the second rotating shaft, deflecting roller is arranged in the second rotating shaft, and runner is arranged in the first rotating shaft, head end lid circumference
On be fixedly installed change, engaged transmission between interior runner and deflecting roller, engaged transmission between deflecting roller and runner, deflecting roller with turn
Inside gear drive between ring.
Described external compression bar centrage is positioned in two different planes from the centrage of center-pole.
Copper sheathing it is provided with between center-pole and end cap.
Before work, inner press roll does not contacts with outer pressure roller, receives in outer pressure roller and external compression bar.Stainless steel inner lining is put into needs repair
In multiple pipeline.Rotatably compressing nut makes center-pole move to head end lid.The inner press roll outer pressure roller of extrapolation, external compression bar is along head end lid
Extend out with the shifting chute in end cap.After clamp nut is tightened.Center-pole high speed rotating, by interior runner, deflecting roller, runner band
Rotating Vortex between dynamic change and head end lid and center-pole.Between inner press roll and outer pressure roller, friction rotates simultaneously so that outer pressure roller
And counter rotating between center-pole.Rub between outer pressure roller and stainless steel inner lining.
Owing to external compression bar centrage is positioned in two different planes from the centrage of center-pole, outer pressure roller is with stainless
Contact line between steel lining is parallel to the centrage of external compression bar, produces with stainless steel inner lining in outer pressure roller rotary course
It is parallel to the frictional force of center-pole, controls the direction of rotation of outer pressure roller, outer pressure roller can be made to advance towards end cap and expand
Footpath operation.
Finally should be noted that: it is only limited by above example in order to the technical solution of the utility model to be described
System；Although being described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the field should
Understand: still detailed description of the invention of the present utility model can be modified or portion of techniques feature is carried out equivalent and replace
Change；Without deviating from the spirit of technical solutions of the utility model, it all should contain the technical scheme being claimed at this utility model
In the middle of scope.
