Abstract
The utility model discloses an utilize small roller footpath collars that condemned big roller footpath collars made, this small roller footpath collars includes condemned big roller footpath collars and middle cover, middle cover is the hollow cylinder structure, middle suit in condemned big roller footpath collars hole, big roller footpath collars with middle cover interference fit, the designing requirement outer diameter of small roller footpath collars is arrived in the outer fringe coping of condemned big roller footpath collars. The technical scheme of the utility model make simply, structural design is reasonable, and maneuverability is strong.
Description
Technical field
This utility model relates to high-speed wire mill apparatus field, utilizes written-off big roller footpath collars particularly to one
The pony roll footpath collars made.
Background technology
Second and third high line production time of Bei Ying steel rolling mill has connect last decade, and a large amount of collars external diameters are close to scrapping size
(175mm).Little external diameter collars brings two problems, the first roller case two roll mandrel limit to adjust a size of 176mm-190mm,
The little external diameter pinch roll of 175mm cannot play the purpose controlling product afterbody ring, and strong influence produces direct motion and outward appearance matter
Amount.Secondly after reducing because of external diameter, collars Year's consumption increases, and within 2013, consumes 20 (normal consumption 10, abnormal consumptions 10 altogether
Sheet), close to the 10.4% of backlog total, normal production if things go on like this will be affected because of collars lazy weight.Bei Ying steel rolling mill
Three-hypers line pinch roll collars a size of Ф 180/175* Ф 87.32*72mm, need to be equipped with 192 collars by specification rolling yield and follow
Ring uses.Run over 10 years that a large amount of collars external diameters are close scraps size (175mm).Pony roll footpath collars has affected normal production and dish
Volume presentation quality.And a large amount of Ф 191* Ф 120*72mm collars has been scrapped in four high line finish rolling.Both thickness is identical, can add in order to
With.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide one and utilizes written-off big roller footpath collars system
The pony roll footpath collars become, concrete technical scheme is as follows:
A kind of pony roll footpath collars utilizing written-off big roller footpath collars to make, this pony roll footpath collars include written-off greatly
Roller footpath collars and intermediate sleeve；
Described intermediate sleeve is hollow cylinder structure, and described intermediate sleeve is loaded on described written-off big roller footpath roll collar inner hole；Institute
State big roller footpath collars and described intermediate sleeve interference fit；
The outer rim reconditioning of described written-off big roller footpath collars requires outside dimension to the design of pony roll footpath collars.
Described a kind of pony roll footpath collars utilizing written-off big roller footpath collars to make, its preferred version is described to report
The useless size after the collars reconditioning of big roller footpath is Φ 185 × Φ, 120 × 72mm.
Described a kind of pony roll footpath collars utilizing written-off big roller footpath collars to make, its preferred version is described centre
The outside dimension of set is Φ 120, and internal diameter size is Φ 87.34, and height dimension is 72mm.
Described a kind of pony roll footpath collars utilizing written-off big roller footpath collars to make, its preferred version is described big roller
Footpath collars coordinates the magnitude of interference reaching 0.05mm-0.08mm with intermediate sleeve；

Set is 0.010mm with the axiality of big roller footpath collars.
The beneficial effects of the utility model: the technical solution of the utility model is simple to manufacture, convenience, workable, this
The utility model of structure utilizes four high line finish rolling collars and three line pinch roll thickness are identical but feature that internal diameter is slightly larger.In the middle of making
Set, cold charge is in collars inner ring integrally formed therewith, and overall dimensions meets pinch roll collars installation requirement, utilize written-off greatly
Roller footpath collars replaces the original collars in pony roll footpath, reaches to improve production efficiency, stabilized product quality, the purpose of saving business capital.
Because the second high-speed wire production line possesses equal conditions, therefore this technology can apply simultaneously to two, three-hypers line.By every collars
6991.45 yuan of meters, can save collars and 13.98 ten thousand yuan/year are lost, will save new collars for enterprise in the long run and purchase fund
134.23 ten thousand yuan.
Therefore this structure is used to have great Social benefit and economic benefit.
