Abstract

The utility model discloses a straightening roller balancing device. The device is characterized by comprising oil cylinders (6) which are fixed at the two ends of the inner side of an upper roller frame (1) and at the two ends of the inner side of a lower roller frame (9), wherein the piston rods of the oil cylinders (6) are connected with a left straightening roller bearing seat (7) and a right straightening roller bearing seat (8) adjacent to each other respectively. The straightening roller balancing device disclosed by the utility model adopts a simple adjusting mode, has strong balancing capability and can conveniently adjust the stress through the oil cylinders on the two sides; and moreover, the device not only can ensure that a straightening roller is in close contact with a support roller in the straightening process, but also can ensure that the center line of the straightening roller after abrasion coping can be conveniently adjusted to be always kept at the same height as the position before replacing the roller in the roller replacing process, thereby being favorable for aligning a spline tooth and a spline sleeve of the straightening roller in the roller replacement so as to realize more convenient roller replacing operation and shorten the roller replacing time.

Description

A kind of smoothing roll bascule

Technical field

The utility model relates to the device that is used for the smoothing roll balance in the straightener.

Background technology

Straightener be cut deal rolling line and finishing line, and traverse on one of main process equipment; Be used for to before the smooth aligning that rolls steel plate after steel plate or the heat treatment of back, the heat treatment steel plate being carried out pre-straightening and the steel plate (or band steel) of normal temperature being aligned, to acquire better glacing flatness.Rely on smoothing roll to act in the aligning process and wait to rectify on the steel plate (or band steel); Make it that elastic-plastic deformation take place, play the effect of aligning, smoothing roll leans on backing roll to support; Bear stressed in the aligning process, therefore how to guarantee that smoothing roll is very important with tight contact of backing roll.In the prior art, the balance of smoothing roll is mainly following form:

First kind of structure: the upper straightening roll bascule is made up of nut, pull bar, dish spring group etc.; Pull bar links to each other with the upper straightening roll bearing block (or the pull bar part is an one with the smoothing roll bearing block), and dish spring group is enclosed within on the pull bar, and nut compact disc spring group realizes precommpression to it; Can adjust the pretightning force of dish spring through the rotation nut; To reach the weight of balance upper straightening roll, make upper straightening roll and backing roll tightly fit together, following smoothing roll relies on self gravity and backing roll to fit together.

Second kind of structure: upper and lower smoothing roll equilibrium phase all is to rely on the effect of dish spring to realize together, is made up of nut, pull bar, dish spring group etc.; Pull bar link to each other with the smoothing roll bearing block (or pull bar part is an one with the smoothing roll bearing block); Dish spring group is enclosed within on the pull bar, and nut compact disc spring group realizes precommpression to it, can adjust the pretightning force of dish spring through the rotation nut; To reach the weight of balance smoothing roll, make smoothing roll and backing roll tightly fit together.

Above structural disadvantages does: a. dish spring is in compressive state in using, and losing efficacy appears in the long-term back of using easily, influences counterbalance effect; B. after roll wear, roller directly diminishes, and can make the dish spring extend, and pretightning force diminishes, and needs manual adjustments; C. after roll wear, move or move down (following smoothing roll) on the center line of smoothing roll, the centering of smoothing roll spline tooth and spline housing when being unfavorable for roll change.

The utility model content

The purpose of the utility model provides a kind of smoothing roll bascule simple in structure, the centering of smoothing roll spline tooth and spline housing when being beneficial to roll change.

To achieve these goals; Adopt following technical scheme: a kind of smoothing roll bascule; It is characterized in that: said device comprises the oil cylinder that is fixedly installed on inboard two ends of top roll frame and the inboard two ends of lower roll frame, and the piston rod of oil cylinder joins with adjacent left side smoothing roll bearing block and right side smoothing roll bearing block respectively.

The utility model adjustment mode is simple; Balanced capacity is strong; Oil cylinder through both sides can make things convenient for the stressed size of adjusting, both can guarantee that smoothing roll closely contacted with backing roll, also can adjust the position of roll wear rear center line; The centering of smoothing roll spline tooth and spline housing when helping roll change is saved the time of roll change.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

As shown in Figure 1, a kind of smoothing roll bascule, top roll frame 1 inboard is fixed with oil cylinder 6 through bearing pin 5 and bearing 4, and the piston rod of oil cylinder 6 links to each other with right side smoothing roll bearing block 8 with the inboard left side smoothing roll bearing block 7 of top roll frame respectively.Equally, lower roll frame 9 also is connected with the left side smoothing roll bearing block 7 and right side smoothing roll bearing block 8 that is positioned at lower roll frame 9 inboards with the same manner through oil cylinder 6.

In the aligning process, through the effect of oil cylinder 6, make smoothing roll 3 closely contact with backing roll 2, guaranteed that power normal delivery in the aligning process is to the basis.

When roll change; Rely on the effect of oil cylinder 6, promote left side smoothing roll bearing block 7 and 8 motions of right side smoothing roll bearing block, before the center line of adjustment smoothing roll 3 and the roll change all the time at sustained height; Guarantee the accurate centering of smoothing roll spline tooth and spline housing, save the time of roll change.

Claims

1. smoothing roll bascule; It is characterized in that: said device comprises the oil cylinder (6) that is fixedly installed on inboard two ends of top roll frame (1) and the inboard two ends of lower roll frame (9), and the piston rod of oil cylinder (6) joins with adjacent left side smoothing roll bearing block (7) and right side smoothing roll bearing block (8) respectively.
