Hole slot diameter is smaller at outside wall surface, the ball steel ball that diameter is equal to hole slot width at inner wall is even placed inside hole slot 131, then
It can only be in the internal motion of reshaper housing 13, and can not reach outside reshaper；131 lower end wall surface of hole slot is thicker, upper end
Wall surface is relatively thin, i.e. upper end hole slot is deeper, and lower end hole slot is shallower；The bottom end of reshaper housing 13 is provided with internal thread.
The plug 15 is shaped like " mountain " font, and top outer diameter is identical with the internal diameter of 13 lower part of reshaper housing,
On be provided with external screw thread；15 lower end of plug is set as frustum cone structure；Plug 15 is internally provided with cylindrical-shaped structure, and body diameter is slightly
Less than crowded swollen 11 internal diameter of body.
9 upper end of stop collar is connect with 1 the lowermost spring base of Power Component, 7 bottom thread, 9 lower end of stop collar and reshaper
13 threaded upper ends of housing connect；Bearing 14 is installed in the junction of 9 lower end of stop collar and 13 upper end of reshaper housing；Guide way
10 are placed in stop collar 9, and two column keys 102 of guide way 10 are embedded in two rectangular recess 91 of stop collar 9；It squeezes swollen

It crosses bearing 14 to connect, the inside of bearing 14 is connect with squeezing swollen 11 lower end of body, and outside and 13 lower end of reshaper housing of bearing 14 connect
It connects；The bottom end of reshaper housing 13 is threadedly coupled with plug 15.
The course of work of this kind of self-rotary hydraulic reshaper is as follows：
Before shaping starts, spring 6 is pressurized, and 5 the top of piston and the lowermost end of top connection 3 offset, due to piston 5 and central tube
8 cross principal columns of a hall cooperation, therefore central tube 8 is in the top of its motion state, and guide way 10 is similarly in the most top of its motion state
End；Two column keys 102 of guide way 10 are located in two grooves 91 of stop collar 9；Since stop collar 9 is fixed, guide way
10 can only axially move along reshaper；Two sliding pins 111 for squeezing swollen body 11 are located at two slide openings 103 of guide way 10
It is interior；It squeezes swollen 11 upper and lower side of body and is both provided with bearing 14, therefore it can only rotate；Ball steel ball 12 is at squeezing swollen body
Between 11 chaste tree dentation turntable structure 112 and six hole slots 131 of reshaper housing 13, and ball steel ball 12 is located at lowermost end.
When shaping starts, reshaper is suppressed, pressure is acted on first on three pistons 5, piston 5 is generated larger
Lower pressure；5 downlink compressed spring of piston, 6 downlink, makes spring 6 store elastic potential energy；The downlink of piston 5 drives center simultaneously
8 downlink of pipe, 8 downlink of central tube drive 10 downlink of guide way；10 downlink of guide way, the oblique slide opening 103 of guide way act on crowded swollen
On the sliding pin 111 of body 11, axial movement is converted into circumferential movement；It squeezes swollen body 11 to rotate, chaste tree dentation turntable structure 112
Ball steel ball 12 will be squeezed to move outward；Due to shallow under depth on the hole slot 131 of reshaper housing 13, ball 12 is outside
It can also be moved upwards in motion process；Increase pressure, ball 12 will form internal surface of sleeve pipe and roll, and casing reaches expanding shaping.
After shaping, pressure is released, acting on lower piston 5 in spring 6 will move up, and finally offset with top connection 3；Piston
5 move up and central tube 8 will be driven to move up, and central tube 8, which moves up, moves up drive guide way 10；Guide way 10 makes to squeeze swollen during moving up
Body 11 reversely rotates, and squeezing the reverse rotation of swollen body 11 will reduce 12 extruding force of ball steel ball, and ball steel ball 12 will be downward
Fall to lowermost end；Final shaping device returns to original state.

It can move round about；It is cylindrical structure to squeeze swollen body bottom end；
The reshaper housing, inside are cylinder latus rectum structure, and internal diameter is identical with stop collar internal diameter；The outer set upper side setting of reshaper
There is external screw thread, this external screw thread can be with the screw-internal thread fit of stop collar lower end；It is circumferentially equidistant in the middle part of housing to open that there are six hole slot, hole slots
Through the inside and outside wall surface of reshaper housing, it is relatively large in diameter close to hole slot at internal face, and it is smaller close to hole slot diameter at outside wall surface；
Hole slot lower end wall surface is thicker, and upper end wall surface is relatively thin, i.e. upper end hole slot is deeper, and lower end hole slot is shallower；The bottom end of reshaper housing is set
It is equipped with internal thread；
The plug is shaped like " mountain " font, and top outer diameter is identical with the internal diameter of reshaper housing lower part, is provided with
External screw thread；Plug lower end is set as frustum cone structure；Plug is internally provided with cylindrical-shaped structure, and body diameter slightly smaller than squeezes swollen internal
Diameter；
The limiting set upper side is connect with Power Component the lowermost spring base bottom thread, stop collar lower end and reshaper housing
Threaded upper ends connect；The junction of set upper side is equipped with bearing outside stop collar lower end and reshaper；Guide way is placed in limiting
In set, two column keys of guide way are embedded in two rectangular recess of stop collar；The inside that swollen body is placed on guide way is squeezed,
Two sliding pins squeezed on swollen body are placed in two slide openings of guide way；Squeeze the shoulder convex of swollen body upper end and the inner ring of bearing
It is connected；Squeeze swollen external side and each reshaper housing hole-and-slot into cavity in be placed with 6 ball steel balls, the diameter of steel ball
