Abstract

The utility model discloses an interchangeable side guide roller for use on a metallurgy production line. Bearings of the same types and specifications are adopted above and below a vertical roller, and the structures and sizes of a drum and a shaft are matched with upper and lower bearing positions, so that the assembly relation of parts inside the vertical roller keeps constant after the upper position and the lower position of the drum of the vertical roller are exchanged. The side guide vertical roller on a strip steel processing production line can be used continually by exchanging the upper position and the lower position of the vertical roller after the vertical roller is scratched and worn by deviated strip steel.

Description

Interchangeability side deflector roll
Affiliated technical field
The utility model relates to a kind of interchangeability side deflector roll of metallurgical production line, and bilateral guide roller is given the correction of band steel guiding, and side is led edger roll energy interchangeability and used.
Background technology
At present, in the production process of strip processing line, because hot-rolled steel winding steel has the not gentle template problem of limit wave, in addition the hardness of material itself is larger, makes to be with steel in the time keeping straight on operation, particularly in the time of threading, whipping, occurred level transverse movement sideslip and bob simultaneously, therefore on strip processing line, be all equipped with the side roller (guide) apron that quantity does not wait, converge in opposite directions the band steel of sideslip by left and right side edger roll, thereby the sideslip being in operation with steel with guidance tape steel, minimizing makes its linear running.In side roller (guide) apron, be that side is led edger roll to the parts that play guiding correction effect with steel, but the strip speed of sideslip is very fast, opposite roller can produce the double action of radial frictional force and axial runout frictional force, again because band steel self gravitation is downward, scuffing and wearing and tearing that vertical roller is subject to are focused mostly at the lower semisection of edger roll cylinder, after asking, need to change the roller of edger roll in the time using one section, and edger roll cylinder in the past up and down transposition secondary utilize, so just caused the problem that edger roll cylinder replacing quantity is many, maintenance of equipment cost is larger.
Summary of the invention
The edger roll of side deflector roll just needed to change roller after the latter half scuffing and serious wear in the past, and the first half of roller mostly is idle running and can't harm.But roller internal structure was in the past: upper bearing (metal) deep groove ball bearing mainly bears radial load, also can bear a small amount of bi-directional axial load simultaneously, and lower bearing is that single row angular contact ball bearing can only bear unidirectional axial load.This structural limitations vertical roller can not exchange up and down use, just caused the waste of the first half of edger roll cylinder.In order to overcome this deficiency, the utility model contralateral guidewire edger roll parts upper/lower terminal adopts the bearing of same type and specification, and vertical roller internal structure matches with it, and edger roll cylinder can upper and lowerly be exchanged, roller after change service courts can continue to use, and plays the function of guiding correction with steel.
The utility model solves the technical scheme that its technical problem adopts: consider that roller is subject to radial load compared with large and be subject to the situation that axial force is not too large in steel running, upper and lower bearing adopts and can bear radially and the single-row angular contact ball bearing of one-way shaft to connected load, reaches the effect that deep groove ball bearing adds thrust ball bearing; And the structure of roller inside, axle is matched.Like this, the first half of roller and the latter half its stress performance after location swap is constant, can exchange use.
The beneficial effects of the utility model are, the side deflector roll that this upper-lower position can exchange, compared with side deflector roll with pre-structure, can extend one times the service life of edger roll, when simultaneously edger roll cylinder upper and lower position exchanges, do not need dismounting yet or change bearing, need dismantle when changing edger roll cylinder compared with bearing in the past and reduce roll changing time yet, like this, save the maintenance cost of equipment, also improved work efficiency.

Fig. 3 is the sectional structural map that novel side is led edger roll parts.
In Fig. 1: 1. left side edger roll, 2. band steel, 3. right side edger roll.
In Fig. 2, Fig. 3: 4. cover plate, 5. go up oil scraper ring, 6. mounting, 7. descends oil scraper ring, 8. upper bearing (metal), 9. roller, 10. lower bearing, 11. axles.
Detailed description of the invention
In Fig. 1, A/F between left side edger roll (1), the right side edger roll (3) of side roller (guide) apron is good according to the width adjustment of band steel (2), in strip processing line production process, while there is sideslip in band steel (2), left side edger roll (1), right side edger roll (3) will be converged guidance tape steel (2) in opposite directions, thereby the sideslip being in operation with steel with guidance tape steel, minimizing makes its linear running.
In Fig. 2, side is led edger roll modular construction: upper bearing (metal) (8) is deep groove ball bearing, lower bearing (10) is single row angular contact ball bearing, roller (9), at internal diameter φ 1, the height a at upper bearing (metal) position place, is all not identical with internal diameter φ 3, height b at lower bearing position place; Axle (11) is also not identical at axle journal φ 2, the φ 4 at upper and lower bearing position place.The upper and lower structure of edger roll inside is completely different, makes the upper and lower position of roller (9) can not exchange use.
In Fig. 3, side is led edger roll modular construction: upper bearing (metal) (8), lower bearing (10) are single-row angular contact bearing, and roller (9) is all identical at internal diameter φ 1, the height a at upper bearing (metal) position place and the internal diameter φ 1 at lower bearing position place, height a; Axle (11) is also identical at the axle journal φ 2 at upper and lower bearing position place.The upper and lower structure of this vertical roller (9) inside is identical with size, and the specification of upper bearing (metal) (8) and lower bearing (10) is also identical, and the assembly relation of other part is also identical up and down.
In the time exchanging the upper-lower position of roller, first pull down cover plate (4), edger roll is taken out from mounting (6), unload after oil scraper ring (5) and lower oil scraper ring (7), axle (11) is extracted out from roller (9), do not need to dismantle bearing, directly will be with the upper and lower Rotate 180 ° of roller (9) of upper bearing (metal) (8) and lower bearing (10), the unworn upper semisection of roller (9) is put into below edger roll, the lower semisection having worn and torn be put into edger roll above; Press again shown in Fig. 3, by axle (11), lower oil scraper ring (7), exchange position and install to mounting (6) with parts such as the roller (9) of bearing, upper oil scraper ring (5), cover plates (4) upper, complete the exchange of edger roll cylinder upper-lower position successively.
