Description
Technical field
The present invention relates to piston ring production equipment technical field, more particularly, to a kind of ring opening is two-way to be stirred arrangement and polishes
Device.
Background technology
In the production process of piston ring, have and ring is carried out cut, then to carrying out this two procedures of polishing at cut；Existing
It is typically all that good mouth is broken on ring present cut machine in technology, then the piston ring breaking good mouth is taken away polishing by workman, has plenty of handss
Work is polished one by one, so the preferable still inefficiency of the piston ring quality of polishing, and human cost is high；Some enable automatization
The equipment of polishing is typically also that needs manually by piston ring, by marshalling at cut and then polish by feeding, and workman needs to stand in one
Ceaselessly set right break location on side, and operation more bothers, and the cut polishing of piston ring is also employing hydraulic pressure one by one
The mode that cylinder pushes is polished, and the comparatively fine single polishing support force of piston ring not easily bends, and stability is poor.
Authorize the patent documentation of Publication No. cn103753374 b, date of publication is on 02 17th, 2016, it discloses
A kind of piston ring automatic opening trimming machine, the arrangement achieves piston ring with opening up horizontal suspension type numerical control pusher mode feeding,
Can be accurately positioned during pusher, binder is reliable and stable, improve production efficiency, reduce cost it is ensured that the processing of piston ring is smart
Degree and crudy；But this equipment does not effectively combine with cut machine, remain and operate after good mouth is broken on cut machine
Personnel manage the opening of piston ring, opening up be placed on horizontal feeding t type guide plate, polishing from cut machine to cut still needs
Expend larger manpower and this device structure is complex.Therefore need to design a structure simply and enable auto arrangement,
And arrange the equipment that speed is fast and accurate, polishes in batches after arrangement.
Content of the invention
An object of the present invention be for the deficiencies in the prior art in place of, overcome piston ring in prior art and broken mouth
Do not enable auto arrangement afterwards, some auto arrangement device structure complex array effect on driving birds is not goods, and then do not enable piston ring and open
The problem of mouth batch polishing.Provide a kind of two-way the stirring of ring opening to arrange and sanding apparatus.
