Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
Technical solution provided by the utility model is illustrated in more detail with reference to Fig. 1 to Fig. 4.
As shown in Figures 1 to 4, originally can position inner intumescence type rolling tools includes：
Retainer 10 surround on retainer 10 and the multiple roller slots 20 radially opened up is distributed with, tight in each roller slot 20
It is close that roller 30 is installed；
Mandrel 40, axial activity are threaded through 10 middle part of retainer, and the mandrel 40 is docked with the inner end of each roller 30 simultaneously,
Whole roller 30 can be driven to surround the structure of encircling to be formed when 40 axial displacement of mandrel to expand or inwardly bounce back outward, at this time
Each roller 30 realizes upper and lower displacement in corresponding roller slot 20.
The utility model protects one kind that can position inner intumescence type rolling tools, and mandrel 40 is axial to be movably arranged on retainer 10
On, it is distributed with multiple rollers 30 in 40 outside of mandrel, mandrel 40 and roller 30 cooperate, and roller 30 is radial or slightly
It is tiltedly mounted on retainer 10, mandrel 40 and roller 30 are fitted close, when work, first by rolling tools clamping in lathe
Or machining center, then the whole roller 30 on retainer 10 is surrounded to the structure of encircling to be formed (i.e. each roller 30 surrounds
Form the overall structure around 40 outside of mandrel) minimum degree is bounced back to, the pipe expanded required for then rolling tools stretch into
It is interior, it then drives 40 axial displacement of mandrel and roller 30 is driven to expand outward, the inner wall contact of 30 outer end of roller and pipe, in pipeline
Inner wall is rolled, and tube wall metal is forced to extend into predeterminable level, and caliber increases, until reaching expansion requirements, when exiting,
Negative direction drives 40 axial displacement of mandrel, roller 30 to recycle, and mandrel 40 automatically exits from, after release can by rolling tools from
It is taken out in pipe, pipe expansion segment is still cylindrical after this rolling tools ensures expanded joint, and auto-feed when processing may be implemented is moved back
Go out, can reliably, efficiently realize tubular expansion operation.
As a kind of preferred or optional embodiment, the front end outer side of mandrel 40 is equipped with the first default taper, mandrel 40
Front end be in beloid setting；It is default that the outside of the roller 30 is equipped with second be adapted to the first default taper of mandrel 40
The lateral surface of taper, 40 front end outer side face of the mandrel and 30 inner end of roller connects.
In the present invention, mandrel 40 and roller 30 have certain taper allow distribution periphery roller 30 more
Add and reliably docked with mandrel 40, when assembly, roller 30 is opposite with 40 taper direction of mandrel so that tubular expansion operation more may be used
It leans on, and ensures that pipe expansion segment is still cylindrical after expanded joint.
Moreover, certain feeding angle is preset between roller 30 and mandrel 40, to realize auto-feed when processing.
Preferably, the inclined-plane 21 that inside is equipped with and 30 lateral surface of roller is adapted to of roller slot 20, not only prevents plowing from rolling in this way
30 side of column can also limit roller 30 and be detached from retainer 10, have effects.
It is worth mentioning that：The setting on inclined-plane 21 can be fitted close with 30 lateral surface of roller so that roller 30 can also
Rotation, but not it is detached from retainer 10 outward, to the rolling effect of inside pipe wall when further ensuring expansion.
Further, for the roller 30 in this case around being symmetrically distributed on retainer 10,40 outside of such mandrel is symmetrical
Ground is distributed preferred 3-5 roller 30, can efficiently, steadily realize tubular expansion operation, and maintaining is convenient, and roller 30 acts
It is unified.
It is respectively equipped with guide surface 31 in the front and back ends of roller 30 so that when mandrel 40 advances and exits, reduce 30 He of roller
The interference effect of mandrel 40 ensures the smooth, steady of work, avoids blocking.
Be additionally provided with the spacing collar 50 for expanding displacement outward for limiting roller 30 outside retainer 10, the roller 30 to
It is outer expand and and spacing collar 50 when contacting, the stopping of roller 30 extends out, and degree is extended out at this time for maximum, before mandrel 40 also stops continuation
Into.
Spacing collar 50 is preferably fixed on 10 outside of retainer by structures such as the screws that is radially arranged, and dismounting is easy for installation；
Spacing collar 50 also ensures roller 30 without departing from retainer 10, and roller 30 is also avoided constantly to extend out and self structure is caused to become
Shape.
In the present invention, so that it is relatively reliable that mandrel 40 works, bearing block preferably is installed on retainer 10
60, the mandrel 40 include positioned at front end and docked with roller 30 work department 41, positioned at the rod-shaped interconnecting piece 42 at middle part and position
Mounting portion 43 in rear end, the interconnecting piece 42 extend through bearing block 60, at the position that interconnecting piece 42 and work department 41 connect
It is arranged with the first spring 70 outside, 70 both ends of the first spring are connected with work department 41, bearing block 60 respectively.
Such structure setting so that 40 front end of mandrel can avoid loosening always with 30 closed butt joint of roller, ensure expansion
When steady and sustainability.
As a further improvement, sleeve 80 is equipped with outside mounting portion 43, in the portion that interconnecting piece 42 and mounting portion 43 connect
Position is outer to be arranged with second spring 90, and 90 both ends of the second spring are connected with sleeve 80, bearing block 60 respectively.
It is arranged with bearing with solid lubricant 100 outside the position that interconnecting piece 42 is located in bearing block 60, hole is used in combination to be limited with baffle ring
In bearing block 60, ensure that the reliability that mandrel 40 moves, axial displacement are flexible.
Preferably, 90 both ends of second spring are connected by spring washer 120 and sleeve 80, bearing block 60 respectively, and docking is more
Add reliable.
In conclusion in it originally can position inner intumescence type rolling tools, mandrel 40 and roller 30 have certain taper, core
40 outside of axis is symmetrically distributed multiple rollers 30, when assembly roller 30 with 40 taper direction of mandrel on the contrary, after to ensure expanded joint
Pipe expansion segment is still cylindrical, has certain feeding angle to realize auto-feed when processing between roller 30 and mandrel 40.
The operation principle of this rolling work is as follows：Rolling work clothes are clipped in lathe or machining center first, then will be protected
It holds frame 10 and retreats to 40 predeterminated position of mandrel, in the pipe expanded required for then rolling tools stretch into, make mandrel 40, roller 30, pipe
Sub- inner wall is mutually adjacent to pusher and starts to process into mandrel 40, and mandrel 40 pushes ahead (it is counterclockwise that may be otherwise) clockwise,
Roller 30 then reversely rotates, and is rolled in inner wall of the pipe, tube wall metal is forced to extend so that caliber increases, until reaching swollen
Until swollen requirement, when exiting, mandrel 40 only need to be done to rotation counterclockwise, mandrel 40 will automatically exit from, can be from pipe after pine
Interior taking-up.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
