Description
Technical field
The utility model belongs to electro-mechanical arts, especially relates to a kind of sky for finishing wire unit and crosses ring oiler.
Background technology
Mm finishing mill unit is used for high-speed rod workshop, is generally made up of eight rolling mills, is overhang roll ring gantry, and topcross 45 ° is alternately arranged.Pre-finishing mill group also alternately arranges unit for topcross 45 °, and two rolling mills are combined into a unit, totally two unit four rolling mill compositions.
Production-line arrangement has reducing-sizing mill, and therefore when producing large gauge product, pre-finishing mill group or mm finishing mill unit need gap to produce according to technological requirement.In order to save electric energy, when pre-finishing mill group or mm finishing mill unit gap, change into inactive from normal rotation.But cause unit to generate heat after continuing through unit to prevent red steel, impact even damaging the sealing of unit roll shaft and other parts, needing to continue to open collars cooling water and continuous spraying cooling is carried out to unit.After unit stall, roll shaft loses centrifugal force, high-pressure cooling water is directly injected to roller case roll shaft surface, the original double-lip seal of roll shaft cannot effectively stop cooling water to invade in unit by the sealing of roller case roll shaft, thus invading in the oil lubricating system of unit, after lubrication station water inlet, oil causes emulsion deterioration on the one hand, reduce oil quality and service life, cause the consumption of lubrication station filter inlet high-precision filter element to rise; The stable operation of the high-speed equipments such as another aspect serious threat production line mm finishing mill unit, reducing-sizing mill, pinch roll and Laying head.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of good sealing effect, long service life, and the sky for finishing wire unit crosses ring oiler.
To achieve these goals, the utility model is by the following technical solutions: a kind of sky for finishing wire unit crosses ring oiler, comprise the ring oiler main body be located between roll shaft and roller case panel, described ring oiler main body has the seal face can fitted with roller case panel surface and the inner ring that can be connected with roll shaft, and described seal face and roller case panel junction form the first seal groove; A double-lip sealing ring is compressed bottom first seal groove and between roller case panel; Along the narrow seal groove that described first seal groove madial wall one cast circularizes, be provided with in described narrow seal groove and contact and " X " shape sealing ring compressed with roller case panel surface; Described ring oiler main body inner ring place is provided with the second seal groove, in this second seal groove, is provided with " O " shape sealing ring." X " shape sealing ring that ring oiler main body end face of the present utility model is installed by newly-designed narrower annular seal groove, can be fitted on roller case panel tightly.When ring oiler is tightly fitted on roller case panel by roll shaft protective cap; wherein two sealing lips of " X " shape sealing ring and roller case panel fit tightly; static sealing very is reliably constituted between the two other sealing lip of " X " shape sealing ring and roller case panel; effectively prevent cooling water from the intrusion of ring oiler main body and roller case panel; and " O " shape sealing ring arranged can realize the sealing in roll shaft and ring oiler main body; lips movable sealing and the wider seal groove of ring oiler fit tightly, and serve the effect of sealing further.
Further, described " X " sealing ring both sides are circumferentially evenly equipped with two sealing lips, form circular arc-shaped recess between adjacent seals lip; Two sealing lips of described " X " sealing ring wherein side are pressed in bottom narrow seal groove, and " X " sealing ring other side two sealing lip is pressed in roller case panel.Such double-lip seal and both sides sealing place all form two seals, and sealing reliability is good.
In sum, the utility model has the intrusion that effectively can control mm finishing mill unit cooling water, greatly reduces the risk of lubrication station water inlet.

Detailed description of the invention
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As Figure 1-5, a kind of sky for finishing wire unit crosses ring oiler, the roll shaft 1 that described mm finishing mill unit comprises roller case, is located at the roller case panel 2 of roller box top and is installed on roller case panel 2.The described sky for finishing wire unit is crossed ring oiler and is comprised ring oiler main body 3, and described ring oiler main body 3 is located at roll shaft 1 and roller case panel 2 socket place.
Concrete, as shown in Figure 3, described ring oiler main body 3 has seal face and inner ring, described seal face is located at ring oiler main body 3 outer ring, and seal face can be fitted with roller case panel 2 surface, realizes being tightly connected, inner ring can be tightly connected with roll shaft 1, described seal face and roller case panel 2 junction form the first seal groove 4 of annular, and the width of narrow seal groove 41, first seal groove 4 circularized along described first seal groove 4 madial wall one cast is greater than the width of narrow seal groove; Compress a double-lip sealing ring 7 between seal face and roller case panel 2, this double-lip sealing ring 7 is positioned at the first seal groove 4 inner bottom part, and the cross section of this double-lip sealing ring 7 takes the shape of the letter U;
Moreover the opening of described narrow seal groove 41 is towards rod case panel 2 surface, and " X " shape sealing ring 6 in narrow seal groove 41, should compress with roller case panel 2 surface contact by " X " shape sealing ring 6, realize sealing; Described " X " sealing ring 6 both sides are circumferentially evenly equipped with two sealing lips 61, form circular arc-shaped recess 62, as shown in Figure 4 between adjacent seals lip 61.Two sealing lips of described " X " sealing ring 6 wherein side are pressed in bottom narrow seal groove 41, and " X " sealing ring 6 other side two sealing lip is pressed on roller case panel 2.
Preferably, described ring oiler main body 3 inner ring place is provided with second seal groove 31, in this second seal groove 31, is provided with " O " shape sealing ring 8, should can realize sealing with roll shaft 1 close contact by " O " shape sealing ring 8.
When mm finishing mill unit gap is produced; original dynamic ring oiler is dismantled; the dirt that roller case panel 2 seals position is cleaned out; according to the installation method of common ring oiler; sky is crossed ring oiler to load, evenly compress, after installing roll shaft protective cap 5; check " X " shape sealing ring 6 of ring oiler and the laminating situation of roller case panel 2 with clearance gauge, then check roller case flooded condition according to normal roller case spray test.Dismounting is simple, and easy to use, the sealing effectiveness of water-inlet-proof clearly.In order to expand the empty scope of application crossing ring oiler, described sky is crossed ring oiler and is arranged different dimensions, point " 10 " and " 8 " two kinds according to roller case, and wherein " 10 " ring oiler is due to pre-finishing mill group, and " 8 " ring oiler is for mm finishing mill unit.Produce in pre-finishing mill group or mm finishing mill unit gap, and use this sky to cross ring oiler, effectively can control the intrusion of pre-finishing mill group or mm finishing mill unit cooling water, greatly reduce the risk of lubrication station water inlet.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
