(I) technical field

The invention relates to a leveling machine, in particular to a monotonous metal plate leveling machine.

(II) background of the invention

Each upper working roller of the existing single-adjustment type metal plate leveler is fixed on an independent upper beam, and each upper beam is controlled to lift by an independent pressing device, so that the position of each upper working roller is adjusted, a proper roll gap is adjusted, and the metal plate is leveled. Compared with an integral beam type metal plate leveling machine, the single type metal plate leveling machine can realize more forms of roll gap adjustment, the leveling capability and the leveling effect are superior to those of the integral beam type metal plate leveling machine, and the application range in the practical production is wider and wider.

The screw-down device of the existing single-adjustment type metal plate leveler realizes the lifting of an upper beam through two groups of screw rods and screw pairs (or oil cylinders) arranged at two ends of the upper beam. In the high-strength sheet leveler, the number of working rolls is large, the roll diameter and the roll distance of the working rolls are small, and the outer diameters of a lead screw and a screw pair (or an oil cylinder) of a screw-down device are small. In the process of adjusting the position of the upper working roll, the precise adjustment of the position of the upper working roll is realized by precisely controlling a lead screw and a screw pair (or an oil cylinder); in the plate flattening process, a lead screw and a nut pair (or an oil cylinder) bear huge straightening force transmitted from a working roller and an upper beam. Lead screw and nut pair (or oil cylinder) with small outer diameter for precise transmission in the process of plate leveling are deformed when bearing huge leveling force, and the position adjustment precision of the subsequent upper working roll is deteriorated, thereby affecting the plate leveling quality. In addition, the screw and the nut pair (or the cylinder) may not receive the correction force, and may be damaged.

Disclosure of the invention

In order to make up for the defects of the prior art, the invention provides the single-adjustment type metal plate leveler which ensures long-term accurate operation and stable and reliable performance.

The invention is realized by the following technical scheme:

the utility model provides a monotonic metal sheet material leveler, includes the host computer frame, installs down the work roll on the host computer frame, and lower work roll top is equipped with work roll, characterized by: the upper working rolls are arranged on upper roll bearing seats, each upper roll bearing seat is composed of a first upper roll bearing seat and a second upper roll bearing seat, and the upper working rolls at two ends are respectively arranged on the first upper roll bearing seats; when the number of the middle upper working rolls is even, every two adjacent middle upper working rolls are arranged on a second upper roll bearing seat; when the number of the middle upper working rolls is odd, the upper working rolls positioned at the output end are arranged on the first upper roll bearing seat, and every two other adjacent upper working rolls are arranged on the second upper roll bearing seat.

The first upper roll bearing seat is arranged at the bottom end of the first upper beam, and the second upper roll bearing seat is arranged at the bottom end of the second upper beam; a first nut is fixed at the top of the first upper beam, and a second nut is fixed at the top of the second upper beam; the first screw nut is arranged on the first lead screw, and the second screw nut is arranged on the second lead screw; the first lead screw and the second lead screw are respectively arranged on the screw-down device.

Go up the work roll top and be equipped with the backing roll, the backing roll passes through the backing roll assembly jig to be installed in first upper beam or second upper beam bottom.

And guide rail plates are respectively arranged on the side surfaces of the first upper roller bearing seat and the second upper roller bearing seat.

The invention has the beneficial effects that: the size of the side surface of the upper beam and the arrangement size of the lead screw and the nut are doubled, the outer diameter of the nut is doubled, the correction force capable of being borne is quadrupled, and the safety coefficient of the lead screw and the nut during plate correction is doubled; the stability of the screw rod and the screw nut in the working state is greatly improved, and the long-term stable and accurate operation of the screw-down device is ensured.

The first upper roll bearing seat 5 is arranged at the bottom end of the first upper beam 7, and the second upper roll bearing seat 6 is arranged at the bottom end of the second upper beam 8; a first nut 9 is fixed at the top of the first upper beam 7, and a second nut 10 is fixed at the top of the second upper beam 8; the first screw nut 9 is arranged on a first lead screw 11, and the second screw nut 10 is arranged on a second lead screw 12; the first lead screw 11 and the second lead screw 12 are respectively mounted on the screw-down device 13. And a supporting roller 14 is arranged above the upper working roller 3, and the supporting roller 14 is arranged at the bottom of the first upper beam 7 or the second upper beam 8 through a supporting roller assembly frame 15. Guide rail plates 16 are respectively arranged on the side surfaces of the first upper roll bearing seat 5 and the second upper roll bearing seat 6.

When the number of the upper working rolls 3 is even, the working rolls 3 at two ends, the first upper beam 7, the first lead screws 11 and the first nuts 9 of the screw-down device 13 keep the original one-to-one relative structural form unchanged, the rest upper working rolls 3 are set to be two adjacent sets of working rolls 3 which are arranged on the common second upper beam 8, the position adjustment of the common upper beam is realized by the second lead screws 12 and the second nuts 10 of the screw-down device 13, and the straightening force from the plate is borne when the plate is straightened, because the side of the second upper beam 8The surface size is twice of the original upper beam, the arrangement size of the second lead screw 12 and the second nut 10 of the screw-down device is also twice of the original size, the outer diameters of the second lead screw 12 and the second nut 10 are twice of the original size, and theoretically, the correction force capable of being born is four times of the original correction force (according to the formula S = pi R)²The cross-sectional area becomes 4 times as large).
