Specific embodiment
Embodiment with reference to the accompanying drawing is described further the present invention:
As shown in Fig. 1,2,3,4,5, a kind of annular element inner hole numerical control hydraulic shape expanding machine, including Jiao Xing pawl mechanism 1, support base 2, master
Oil cylinder 3, rotating mechanism 4, drawback cylinder system 5, measuring device 6 and hydraulic, automatically controlled, lubrication, cooling and other auxiliary systems
System；It is set on school shape pawl 14 to annular workpieces by automatic bulging.Hydraulic, automatically controlled, lubrication and cooling system are respectively the present invention
Equipment provides power, control, lubrication, refrigerating function, realizes the automation of Bulging Process.
As shown in figure 3, Jiao Xing pawl mechanism 1 includes work support platform 11, guide support 12, pyramid pull rod 13, school shape pawl
14, big nut 15, wearing plate 16；Wearing plate 16 is set between pyramid pull rod 13 and school shape pawl 14, and wearing plate 16 is coated on
13 surface of pyramid pull rod；It is closely packed together between pyramid pull rod 13 and school shape 14 by wearing plate 16, bears pyramid and draw
The radial forces that the drop-down of bar 13 generates, wearing plate 16 play the role of load, anti-attrition.
11 top of work support platform is provided with 12 rectangle guide grooves, and certainly, the quantity of guide groove can be according to setting
The difference of standby size and it is different；Rectangle guide groove surrounds the center radiation profiles of work support platform 11；12 guide supports
12 are just plugged in one by one in 12 rectangle guide grooves of work support platform 11, and can be free to slide in it；
One end of guide support 12 and school shape pawl 14 are connected firmly together by bolt and card key, guide support 12 and school shape pawl 14
It may be integrated design；In this way, school shape pawl 14 can with guide support 12 pyramid pull rod 13 tension effect and
Under the action of drawback cylinder system 5, radial motion is done around the center of work support platform 11 along guide groove；When bulging, pyramid
The tension of pull rod 13 acts on school shape pawl 14, guide support 12, and the two is far away from the centre on work support platform 11, outward
Movement；As soon as after time bulging, school shape pawl 14, guide support 12 are under the effect of drawback cylinder system 5, towards work support platform
Centre movement on 11.
As shown in Fig. 1,4, support base 2 includes upper flange 21, column 22 and lower flange 23；Upper flange 21 and work support platform
11 underrun bolt connects firmly, and lower flange 23 and the cylinder cap flange 31 of master cylinder 3 are connected firmly by bolt；In this way, passing through support
Seat 2 links together master cylinder 3 and Jiao Xing pawl mechanism 1, forms equipment body.
Master cylinder 3 is made of cylinder cap flange 31, cylinder bottom flange 32, piston rod 33, cylinder barrel 34；Piston rod 33 and pyramid are drawn
Bar 13 is connected firmly by a big nut 15；Cylinder bottom flange 32 can be used for fixed total system of the present invention, or be fixed on ground, or solid
Due to workbench；
Master cylinder 3 provides power for bulging: it is pulled through big nut 15 under piston rod 33, pyramid pull rod 13 driven to move downward, rib
The slope driving of cone pull rod 13 school shape pawl 14 moves outward along guide groove, thus to being covered on the outside of the shape pawl of the school 1.1.4
One outer expansion force of annular workpieces completes bulging function；After bulging, 33 uplink of piston rod drives pyramid by big nut 15
Body pull rod 13 moves upwards, and school shape pawl 14 resets under the thrust of drawback cylinder 15.
As shown in Figure 1, 2, 3, rotating mechanism 4 includes rotationally supporting deflector roll 41, support frame 42 and rotation motor 43；Whirler
Structure 4 has three groups, is separately mounted on three guide supports 12, and 120 ° of their intervals are evenly arranged；Rotating mechanism 4 is fixedly mounted on
On guide support 12, when bulging, radial motion is done with guide support 12；At the end of bulging, the rotation of rotating mechanism 4
Support deflector roll 41 independent under the driving of rotation motor 43 can be freely rotated, so that annular element be driven to rotate；So as to carry out
Second, third time bulging ...；Due to that can have gap between two neighboring school shape pawl 14, if a bulging, annular element
On can gap leave straight flange either trace, so having to eliminate this trace by multiple bulging；It in general, be into
Capable bulging more than three times, so must have rotating mechanism 4.
As shown in Figure 1,3, drawback cylinder system 5 includes: cylinder support 51, drawback cylinder system 52, push-and-pull support 53；Oil
Cylinder support 51 is fixed on 11 bottom surface of work support platform, and push-and-pull support 53 passes through work support platform 11 and is fixed on guide support 12
On, drawback cylinder system 52 is hinged with cylinder support 51, push-and-pull support 53 respectively by pin shaft；
Drawback cylinder system 52 is big intracavitary always full of the hydraulic oil for keeping certain pressure, in this way, the work of drawback cylinder system 52
Stopper rod passes through push-and-pull support 53, thrust certain to guide support 12 always, i.e. reset force, so that school shape pawl 14 passes through wearing plate
16 fit tightly on always on the inclined-plane of pyramid pull rod 13, so that school shape pawl 14 is done with the axial movement of pyramid pull rod 13
Radial motion.
As shown in Figure 1,3, measuring device 6 includes: measurement bay 61 and displacement sensor 62；Displacement sensor 62 can measure
The axial displacement data of pyramid pull rod 13, then the outer diameter data of school shape pawl 14, i.e. annular workpieces are calculated by controller
Inner diameter values.
The present invention is capable of the annular element of bulging various sizes, and implementation method is to be superimposed different thickness in the outer circle of school shape pawl 14
The mold of size is spent, specific size range can cover very wide.
The working principle of the invention and the course of work are as follows:
As shown in Fig. 1 to 5, cooperated by the inclined-plane of school shape pawl 14 and pyramid pull rod 13, the axial direction of pyramid pull rod 13 is moved
Turn turns to moving radially for school shape pawl 14, and is converted into the outer of school shape pawl 14 after the lower pulling force of master cylinder 3 is amplified decades of times
Expansive force, i.e. bulging power needed for annular workpieces bulging.
As shown in Figure 1, the present invention is in initial position before bulging starts, i.e. master cylinder 3 is fully extended, Jiao Xing pawl mechanism 1
In minimum position, the minimum outer diameter of Ji Jiaoxing pawl mechanism 1；Annular workpieces are sleeved in Jiao Xing pawl mechanism 1, bulging starts,
Master cylinder 3 pulls down, swollen outside Jiao Xing pawl mechanism 1；When the data and target data measured by measuring device 6 are coincide, under master cylinder 3
It draws and stops, holding position is motionless after a certain period of time, pushes up on master cylinder 3, and one time bulging terminates；Rotating mechanism 4 works, and drives annular
Workpiece rotation predetermined angular, such as 15 °, master cylinder 3 pulls down, and is repeated once Bulging Process, i.e., secondary bulging ... ...；Repeat with
Upper process, until obtaining the annular workpieces that meet the requirements.In practical application, it is only necessary to which 3 to 5 bulgings can be obtained satisfied knot
Fruit.The above Bulging Process is automatically performed under the control of apparatus control system.
The above described is only a preferred embodiment of the present invention, being not that the invention has other forms of limitations, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But without departing from the technical solutions of the present invention, above embodiments are made according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within the protection scope of technical solution of the present invention.
