Combination type pressing-down balancing device and its control method

Abstract

The invention discloses a combination-typed press-down balance device and a control method thereof. The device comprises a press-down hydraulic cylinder, a balance hydraulic cylinder, a connecting sleeve and a bent hook which are engaged with each other by a gear, a supporter, a balance colloid and a roller slideway H-shaped block. The press-down hydraulic cylinder piston rod is at least two-step diameter-contracting rod; a fine-diameter rod is sheathed with the balance hydraulic cylinder. The end of the balance hydraulic cylinder piston rod is connected with a tooth-shaped connecting sleeve; a connecting sleeve gear is engaged with two opposite bent hooks; the top of the bent hook is provided with a rotation shaft; the two ends of the rotation shaft respectively pass through two shaft end sliding block; the supporter is arranged on a front end cover of the press-down hydraulic cylinder; the two sides of the supporter is provided with a long trough; the shaft end sliding block slides in the long trough of the supporter; the position in the front end cover of the press-down hydraulic cylinder corresponding to the long trough is provided with a balance colloid; the bent hook can be connected with the roller slideway H-shaped block. The combination-typed press-down balance device is used for two-roller or multi-roller continuous rolling mills, can realize the press-down operation and the balance of the roller in narrow rolling machine space and meets the normal production and fast roller switching operation of the rolling machine.

Description

technical field [0001] The invention relates to a reduction balance device and its control method, in particular to a combined reduction balance device and its control method for two-roll and multi-roll continuous rolling mills. Background technique [0002] At present, the pressing hydraulic cylinders and balancing hydraulic cylinders used in rolling mills are separated separately. Generally, a roll needs to have 4 or more balancing hydraulic cylinders. The balancing hydraulic cylinders occupy a large space. Compared with use and maintenance It is troublesome, the cost is relatively high, and the operation of changing rolls is relatively complicated. Taking the three-roll continuous rolling mill as an example, if each roll is equipped with 4 balance hydraulic cylinders, and the balance hydraulic cylinders are installed on a small frame, 12 balance hydraulic cylinders and corresponding piping need to be installed in one rolling mill. This is difficult to do in tight mill sp...
