Embodiment 1

[0023] In order to solve the problem that the driving roller of the single-side driving tension leveling machine is easy to tilt and cause the casting strand to deviate, such as Figure 5 with Image 6 As shown, in this embodiment, a balance mechanism for driving the drive roller of the tension leveler on one side is installed between the tension leveler 2 and the speed reducer 6, such as figure 1 with figure 2 As shown, the balance mechanism includes a slide plate 13 and a support plate 1 that are oppositely arranged. The slide plate 13 is fixed on the side of the tension leveler 2, and the support plate 1 is fixed on the speed reducer 6. The output shaft of the speed reducer 6 is connected to the tension leveler. The upper driving roller of machine 2 is connected;

[0024] Bolt 2 10 is installed on the support plate 1, and the bolt 2 10 is located below the output shaft of the reducer 6. A ball 11 is installed on the end surface of the bolt 2 10, and the ball 11 is in sli...

Embodiment 2

[0029] On the basis of Example 1, such as figure 2 As shown, the body surface of the tension leveling machine 2 is processed with a sliding plate groove 12, and the sliding plate 13 is fixed on the sliding plate groove 12 by screws 14. The sliding plate groove 12 is a plane processed on the body surface of the tension leveling machine 2 to ensure the installation accuracy of the sliding plate 13, save materials and make the installation easier. The slide plate groove 12 is opened on the side of the tension leveler 2 where the reducer 6 is installed. The installation of the slide plate groove 12 on the tension leveler 2 has height and dimension requirements, and the specific is based on the hydraulic cylinder stroke of the tension leveler 2 .

Embodiment 3

[0031] On the basis of Example 2, such as figure 2 As shown, a block 15 is welded on the slide plate 13 , and the block 15 is located between the slide plate 13 and the slide plate groove 12 . Stop block 15 is welded on the bottom surface of slide plate 13, and when slide plate 13 was under force in use, stop block 15 played a position-limiting effect, and slide plate 13 was fixed after installation, does not slide, and during use, ball 11 slides on slide plate 13.

Abstract

The invention provides a balance mechanism for a driving roll of a unilaterally-driven tension leveler. The balance mechanism consisting of a support plate and a slide plate is mounted between a tension leveler body and a speed reducer. In the production process, when the speed reducer droops due to the weight to generate a tilting moment to an upper driving roll on a tension leveler, the power of the speed reducer is transferred to the slide plate through a roll ball on the support plate and is transferred to the tension leveler body through the slide plate so as to support the speed reducer, so that the trends of left and right tilting caused when a casting blank is pressed down by the upper driving roll under the action of a hydraulic cylinder is prevented, and an upper roll of the tension leveler presses down in a state of being completely parallel with a blank surface. The balance mechanism is simple, easy to maintain and independently mounted, so that the maintainability of the whole device is improved. The balance mechanism is applicable to the design of a novel tension leveler and the remolding of an old tension leveler.

Description

technical field [0001] The invention belongs to the technical field of metallurgical continuous casting, and in particular relates to a balance mechanism suitable for driving rollers of a drawing and leveling machine on one side. Background technique [0002] In the design of billet continuous casting machine, due to the requirement of multi-strand number, special steel type and light reduction function of the casting machine, it is necessary to adopt the design of single-frame tension-leveler driven by one side, and adopt the method of continuous arrangement of multiple frames To meet the needs of the continuous casting process, this single-frame tension-leveler with unilateral drive has a relatively simple design, but it is difficult to avoid the disadvantages of the drive system arranged on one side: The tendency of inclination, when the slab is wide, it is easy to bring the possibility of strand deviation. Contents of the invention [0003] The purpose of the inventio...
