Retractable volume equipment drives the intermediate mandril to withdraw, and pushes up swelling shaft 2 and automatically retract, reset under the action of the second dynamic clamping head and quiet clamping head,
And each disjunctor rises by block 3 in the case where no top swelling shaft 2 abuts against, and under the action of the first dynamic clamping head and quiet clamping head 12, Ge Gelian
The body realization of block 3 of rising automatically resets, so that next retractable volume be waited to work.
The present embodiment uses purely mechanical structure, more adaptable there is no the limitation of use environment, improves the effect of production
Rate, and can guarantee better retractable volume precision, play the role of positioning for production high standard, high quality of products;
In addition, the present embodiment takes unitary module to design, the time of replacement mechanical expansion shaft is saved, adapts to variety classes volume
The coiled material folding and unfolding of core uses, and also saves the volume of retractable volume equipment.
As shown in Fig. 4, Fig. 5 and Fig. 9, based on the above embodiment on the basis of, further, first dynamic clamping head and quiet clamping head
12 include that reset screw 121 and first back-moving spring 122, the reset screw 121 are threaded on swelling shaft outer sleeve 1, institute
The one end for stating first back-moving spring 122, which is set in, to be resetted on screw 121 and abuts against with screw 121 is resetted, and described first resets bullet
The other end of spring 122 and the disjunctor block 3 that rises abut against;Specifically, the disjunctor rises to be provided on block 3 and be used for and first back-moving spring
The groove ports of 122 cooperations, the other end of first back-moving spring 122 is located in the groove port, when work, pushes up swelling shaft 2 and abuts against disjunctor
Rise block 3, extends radially the disjunctor block 3 that rises, and the disjunctor block 3 that rises compresses first back-moving spring 122, produces first back-moving spring 122
Raw elastic deformation, and when pushing up swelling shaft 2 and resetting, first back-moving spring 122 restores elastic deformation, to drive the disjunctor block 3 that rises multiple
Position, structure are simple.
As shown in Figure 3 and Figure 9, on the basis of based on the above embodiment, further, the connecting component 5 includes third
Connecting flange 51, bearing part 52 and locking member 53, the bearing part 52 are set on connecting mandrel 4 and are located in the swelling shaft 2 of top, institute

51 are connected in the swelling shaft 2 of top and fix the outer ring of bearing part 52 and top swelling shaft 2;The bearing part 52 preferably uses angular contact axis
It holds, the locking member 53 uses locking nut, can more effectively guarantee that connecting mandrel 4 will not rotate, and ensures that top swelling shaft 2 exists
Retractable volume abuts against disjunctor when working always and rises block 3, ensures the synchronous rotation of extraneous coiled strip cylinder and swelling shaft outer sleeve 1, raising folding and unfolding
The precision of volume, while realizing that connecting mandrel 4 pushes top swelling shaft 2 mobile.
It as shown in Figure 3 and Figure 4, further include pushing up swollen guiding axis 6 further on the basis of based on the above embodiment, it is described
The one end for pushing up swollen guiding axis 6 is connected on the second connecting flange 13, and the other end of the swollen guiding axis 6 in top protrudes into the swelling shaft 2 of top
And cooperated by linear bearing 7 and top swelling shaft 2, swollen guiding axis 6 is pushed up in setting can play the role of branch support swelling shaft 2, make to push up swelling shaft 2
It in stretching and withdrawal, is moved horizontally along the axial direction for pushing up swollen guiding axis 6, guarantees the mobile balance of top swelling shaft 2, avoid top swelling shaft
2 because self weight run-off the straight cause to have disjunctor rise block 3 abut against it is not in place, and for guaranteeing can be more preferable when top swelling shaft 2 resets
Ground and extraneous intermediate push rod cooperate.
Further, limited location snap ring is provided in the top swelling shaft 2, the limited location snap ring is for straight limit bearing 7
Axial float, specifically, the quantity of the linear bearing 7 are two, can better ensure that the swollen guiding axis 6 in top is in steady shape
State, while being conducive to push up the swollen rotation of guiding axis 6, the one end and top swelling shaft 2 of the linear bearing 7 abut against, the other end and limit
Position snap ring abuts against, so that linear bearing 7 be limited, prevents the axial float of linear bearing 7, structure is more firm.
In the present embodiment, it is preferable that second dynamic clamping head and quiet clamping head is second back-moving spring 8, the second back-moving spring 8
It is set on the swollen guiding axis 6 in top;Specifically, when pushing up the stretching of swelling shaft 2, top swelling shaft 2 compresses second back-moving spring 8, makes second to answer
Position spring 8 generates elastic deformation, and when pushing up the withdrawal of swelling shaft 2, second back-moving spring 8 restores elastic deformation, makes to push up by elastic force swollen
Axis 2, which is realized, to be resetted, and structure is more reliable.
As shown in Figures 1 to 5, on the basis of based on the above embodiment, further, the outer wall of the swelling shaft outer sleeve 1
It is arranged at intervals with slide-and-guide component 14, the slide-and-guide component 14 is for the ease of extraneous coiled strip cylinder is inserted in swelling shaft housing
On cylinder 1;Specifically, adjacent disjunctor, which rises, is equipped with slide-and-guide component 14 between block 3, and the slide-and-guide component 14 is along parallel
Be arranged at intervals with three in the axial direction of swelling shaft outer sleeve 1, slide-and-guide component 14 be set, reduce extraneous volume material tube inner wall with
The frictional force of 1 outer wall of swelling shaft outer sleeve makes extraneous coiled strip cylinder be easier to be fitted on swelling shaft outer sleeve 1, at the same be also easier to by
The extraneous coiled strip cylinder that winding is completed is easier to remove.
As shown in figures 3 and 8, further, the slide-and-guide component 14 includes slide-and-guide seat 141 and pulley 142,
The slide-and-guide seat 141 is fixed on swelling shaft outer sleeve 1, and 142 axis of pulley connects on slide-and-guide seat 141;Specifically,
During extraneous coiled strip wound packages is entered swelling shaft outer sleeve 1, the inner wall of extraneous coiled strip cylinder reduces under the action of pulley 142
Frictional force between 1 outer wall of extraneous coiled strip cylinder and swelling shaft outer sleeve, to keep extraneous coiled strip cylinder more labor-saving and rapidly be pushed into swollen
It is removed on outer shaft sleeve cylinder 1 or from swelling shaft outer sleeve 1.
