Abstract

The utility model discloses a sleeve removing device for a rolling mill. A thrust bearing is additionally arranged outside a rotating arm of the sleeve removing device for the rolling mill, and is pressed by a pressing device. Axial force is applied to the rotating arm through the thrust bearing and simultaneously radial friction force is provided, so that the uneven stress of the rotating arm is eliminated and the abrasion of a sliding bearing caused by unilateral friction generated in a rotating process can be avoided.

Description

A kind of rolling mill sleeve barrel moving-out device

Technical field

The utility model relates to the machinery processing apparatus field, particularly a kind of rolling mill sleeve barrel moving-out device.

Background technology

Milling train is the equipment of realizing metal rolled process, and general reference is finished the equipment of stocking production overall process, includes capital equipment, auxiliary equipment, handling equipment and auxiliary device etc.In the operation of rolling, sleeve need be batched the pusher side transportation from the uncoiler side direction, revolute pair in the rolling mill sleeve barrel moving-out device adopts the sliding bearing form at present, see also Fig. 1, be that turning arm 2 is connected on the bearing pin 1 by sliding bearing 3, the characteristics of sliding bearing 3 can not be born axial force, cause sliding bearing 3 uneven wears under the situation of radial force inequality easily, and then damage bearing pin 1 and turning arm 2.Changing bearing pin 1 and sliding bearing 3 wastes time and energy, and influence is produced.

Therefore, how to improve the rolling mill sleeve barrel moving-out device, can enough improve the stressing conditions of sliding bearing 3, prolong 3 service lifes of sliding bearing, and then reduce the maintenance cost of milling train, become the important technological problems that those skilled in the art need to be resolved hurrily.

The utility model content

In view of this, the utility model provides a kind of rolling mill sleeve barrel moving-out device, so that it can improve the stressing conditions of sliding bearing, prolongs sliding bearing service life.

For achieving the above object, the utility model provides following technical scheme:

A kind of rolling mill sleeve barrel moving-out device comprises bearing pin and is connected turning arm on the described bearing pin by sliding bearing that the described turning arm outside increases a thrust bearing, and by hold down gag described thrust bearing is pressed on the described turning arm.

Preferably, described bearing pin end is provided with screw thread, and described hold down gag is and described bearing pin end thread nut engaged.Preferably, described bearing pin end arranges the diameter of threaded part less than the diameter of other parts of described bearing pin.

Preferably, the outer ring of described thrust bearing is equipped with bearing holder (housing, cover).

From technique scheme as can be seen, the rolling mill sleeve barrel moving-out device that the utility model provides, increase a thrust bearing in its turning arm outside, and use hold down gag that thrust bearing is compressed, radial frictional force is provided when by thrust bearing turning arm being applied an axial force, eliminate the cursor unbalance stress, avoid in rotation process, producing monolateral friction, the wearing and tearing sliding bearing.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of rolling mill sleeve barrel moving-out device in the prior art;

The structural representation of the rolling mill sleeve barrel moving-out device that Fig. 2 provides for the utility model embodiment.

The specific embodiment

The utility model provides a kind of rolling mill sleeve barrel moving-out device, so that it can improve the stressing conditions of sliding bearing, prolongs sliding bearing service life, and then reduces the maintenance cost of milling train.

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

See also Fig. 2, the structural representation of the rolling mill sleeve barrel moving-out device that Fig. 2 provides for the utility model embodiment.

A kind of rolling mill sleeve barrel moving-out device that the utility model provides comprises bearing pin 1 and is connected turning arm 2 on the bearing pin 1 by sliding bearing 3 that turning arm 2 outsides increase a thrust bearing 4, and by hold down gag thrust bearing 4 are pressed on the turning arm 2.

Compared with prior art, the rolling mill sleeve barrel moving-out device that the utility model provides, by increase a thrust bearing 4 in turning arm 2 outsides, when turning arm 2 is applied an axial force, offer 2 one radial frictional forces of turning arm, eliminate the cursor unbalance stress, avoid in rotation process, producing monolateral friction, wearing and tearing sliding bearing 3.

Bearing pin 1 end is provided with screw thread, and the hold down gag in the rolling mill sleeve barrel moving-out device that the utility model embodiment provides is and bearing pin 1 end thread nut engaged 5 that preferred, the diameter of bearing pin 1 end thread part is less than the diameter of other parts on the bearing pin 1.

In order to prevent in the course of work that the lubricating oil in the thrust bearing 4 throws away, the thrust bearing 4 that provides among the utility model embodiment is equipped with a bearing holder (housing, cover) 6 in its outer ring.

Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
