Description
Technical field
The present invention relates to a kind of calibrator and method thereof that is applied to tyre rebuilding, belong to the rubber manufacturing machinery field.
Background technology
For elastomeric material that practice thrift to make tire and reduce pollution on the environment thus, the old tire that has been worn to tread contour generally takes to renovate the method for processing at present, to drop into recycle once more.
Generally need to use the tyre surface make-up machine in the existing tire recapping equipment; With the tire clamping to the assembly drum of calibrator; Through pinning the rim of the mouth and inflating so that tire is propped up and located to tire; Calibrator and tire be rotation together under the drive of drive motors, and tyre surface is polished and new tyre surface sticker is combined on the old tire.
Existing tyre surface make-up machine, the assembly drum of its calibrator lack constraint of effective spreading and resetting structure, so the secter pat of assembly drum is easy to dislocation, deadlock phenomenon occur, just need integrally dismantle assembly drum and repair or replace in case this type of problem occurs.
When tire is inflated, the position, rim of the mouth is difficult to fixing and is easy to gas leakage in addition, and the crown of tire and position, rim of the mouth occur eccentric and have influence on tyre surface polishing and applying quality.
Summary of the invention
The present invention provides a kind of calibrator and method thereof of tyre surface make-up machine; Be to address the above problem with defective and in the process of the outside spreading of assembly drum; Secter pat is applied entad constraint and reset response power; To avoid occurring secter pat dislocation and locked problem, solved assembly drum integral demounting and replacing problem, improve the production efficiency of tyre rebuilding.
Another goal of the invention is that the strength that improves between the calibrator internal structure transmits, and guarantees that tire can be clamped effectively and locate.
Goal of the invention also is, can pin tyre rim and keep crown and the position, rim of the mouth has the same center of circle all the time, to improve tyre surface polishing and applying quality, for follow-up vulcanization process provides the good premise condition.
For realizing the foregoing invention purpose, the calibrator of said tyre surface make-up machine includes the tool disk and the circular cylinder that are mutually permanently connected.
At the horizontal guide post of the center fixation of tool disk one, at the outside of guide post socket one conically shaped, fixedly mount a shoring at the guide post front end, shoring is connected in cylinder body through bolt.The support piece of 2 symmetrical distributions is installed between conically shaped and shoring, supports that piece connects outwardly directed locking post.
Along the circumferencial direction of cylinder body, supporting the piece outside to be nested with an assembly drum.
The difference with the prior art part is,
Assembly drum includes several secter pats that along the circumferential direction distribute, and adjacent secter pat is pegged graft each other through sawtooth and is integral.At the excircle of secter pat sheathed one annular gum cover, gum cover is fastenedly connected through screw and one of them secter pat.
Be provided with the tracheae that is communicated with outside gas circuit in cylinder interior, the inner air path that is made up of tracheae extends to the end of conically shaped.
Like above-mentioned scheme characteristic, when Compressed Gas is supported piece through conically shaped jack-up and during with the outside spreading of assembly drum, assembly drum pins tyre rim and inflates to tire.
In this process, annular gum cover applies entad a reseting elasticity to several secter pats all the time simultaneously, and adjacent secter pat also the sawtooth through each other radially with vertical on, form mutual locking, position-limiting action power.Therefore, secter pat can not occur misplacing and mutual locked problem.
Be to improve that assembly drum pins tyre rim and to the efficient of tire inflation, the further improvement project that can take is,
Be provided with the tracheae that is communicated with external environment condition in assembly drum inside, tracheae extends between the secter pat.
Be introduced into the Compressed Gas of inside tires from external environment condition, can get into through the gap of secter pat.When the secter pat retraction resetted, the gas that charges into tire still can be discharged assembly drum through this gas circuit structure.
Further refinement scheme is, described secter pat is provided with the even number greater than 2, and the inner face of each secter pat is set to taper.The outer face of several secter pats, common formation and the corresponding circular contour of tire inward flange.
For improving the strength transfer capability between the calibrator internal structure, between guide post and conically shaped, be provided with spring, spring compression is at the inner face of conically shaped.Along periphery cuff one back-moving spring of supporting piece.
In addition, between tool disk and cylinder body, be provided with sealing ring, between guide post and conically shaped, be provided with an O-ring seal, between cylinder body and conically shaped, be provided with an O-ring seal.
Be used in combination above-mentioned calibrator, the present invention has realized a kind of method for shaping that is applied to the tyre surface make-up machine:
The excircle of assembly drum is inserted at the position, rim of the mouth of tire, feeds Compressed Gas, support piece with assembly drum spreading from inside to outside through conically shaped jack-up to cylinder interior, to the tire inflation so that tire is propped up and is located;
Calibrator and tire rotate under external force together, to the tyre surface operation of polishing and fit;
When finishing above-mentioned tyre surface polishing and fitting operation, cut off external air source, conically shaped, support piece and assembly drum all bounce back and reset, and tire is unloaded from calibrator.
The simultaneously outside spreading of several secter pats of assembly drum is to pin tyre rim and to inflate to tire.Clamp in the process of tire at assembly drum, the annular gum cover that is arranged on the secter pat excircle applies entad a reseting elasticity to it all the time.Sawtooth between the adjacent secter pat, assembly drum radially with vertical on each other the locking, spacing.
On this basis, at assembly drum pinning tyre rim and in the process of tire inflation, the crown of tire and position, rim of the mouth have the same center of circle.
To the tracheae of cylinder body introducing Compressed Gas, extend to the end of conically shaped from the outside.
Through the tracheae of assembly drum to tire inflation, extend to secter pat between.
Promote the conically shaped jacking at Compressed Gas and support that the spring that is pressed on the conically shaped inner face applies a reseting elasticity to it all the time in the process of piece.
Supporting piece outwards to promote in the process of secter pat, cuff applies entad a reseting elasticity to it all the time at the spring of supporting the piece periphery.
In sum, the present invention has the following advantages and beneficial effect:
1, the calibrator and the method thereof of existing tyre surface make-up machine are improved, can be solved secter pat at all and dislocation and locked failure problems occur, reduce the assembly drum integral demounting and change probability, improve the production efficiency of tyre rebuilding.
2, the strength transmission efficiency between the raising calibrator internal structure, tire can be clamped reliably and located.
3, through pinning the position, rim of the mouth, can keep crown and rim of the mouth to have the same center of circle all the time, thereby improve tyre surface polishing and applying quality with to the tire inflation.
