Embodiment 1

[0031] The slider assembly of Embodiment 1 includes a slider body 1, the upper surface and the lower surface of the slider body 1 are respectively provided with several rollers 2, and the outer edge formed by the generatrix at the top of the side of at least two rollers 2 on the upper surface The top surface is higher than the upper surface, and the bottom surface of the outer edge formed by at least two rollers 2 side bottom busbars on the lower surface is lower than the lower surface. It forms an acute angle with the bottom surface of the outer edge.

[0032] In Embodiment 1, the upper surface of the slider body is parallel to the top surface of the outer edge, and the lower surface of the slider body 1 is parallel to the bottom surface of the outer edge; the upper surface and the lower surface of the slider body 1 are respectively provided with a straight cage 3 , The roller 2 is embedded in the straight cage 3 .

[0033] The roll gap adjustment device in Embodiment 1 incl...

Embodiment 2

[0037] The difference between embodiment 2 and embodiment 1 is that the slider body 1 includes a first slider body 1a and a second slider body 1b, the upper surface of the slider body is the upper surface of the first slider body 1a, and the slider body The lower surface is the lower surface of the second slider body 1b, the first slider body 1a and the second slider body 1b are connected by a connecting block 1c, and the connecting block 1c is used to connect with the output end of the reciprocating drive device.

[0038] In Embodiment 2, the first slider body 1a and the second slider body 1b are columnar bodies with an oblong cross section, and the two sides of the first slider body 1a and the second slider body 1b are sleeved respectively. There is an annular cage 9, and several rollers 2 are embedded in the annular cage 9, and several rollers 2 are in motion fit with the corresponding first slider body 1a or second slider body 1b, and the first slider The axial direction o...

Embodiment 3

[0041] The difference between embodiment 3 and embodiment 2 is that the first slider body 1a and the second slider body 1b are respectively provided with oblong hole-shaped annular grooves 13, and the annular grooves 13 run through a long side groove body in the circumferential direction. Rectangular openings are formed on the corresponding upper surface or lower surface, and the rollers 2 are arranged side by side in the annular groove 13. The rollers 2 can roll along the direction of circumferential extension. The straight-line distances between them are all less than the radius of the bottom surface of the roller 2. Among them, a preferred embodiment is that the arc transition portion of each annular groove 13 along the circumferential direction can accommodate at least four rollers 2 .

[0042] The reciprocating drive device of the slider assembly in Embodiment 3 is a servo motor 8c, the output end of the servo motor 8c is connected to the lead screw 11 through the reducer...

Abstract

The invention discloses a driving slider, a roller gap adjusting device and a strip rolling mill. A slider assembly is disclosed. The upper surface and the lower surface of the slider assembly are respectively provided with several rollers, and at least two rollers on the upper surface are sideways The top surface of the outer edge formed by the top bus bar is higher than the upper surface, and the outer edge bottom surface formed by at least two rollers on the lower surface is lower than the lower surface, and the roller axes of the upper surface and the lower surface are parallel , the top surface of the outer edge and the bottom surface of the outer edge form an acute angle with each other. The slider assembly is applied to the roller gap adjustment device. The slider assembly improves the sliding friction between the adjustment block and the bearing block in the traditional adjustment to rolling friction by setting rollers on the surface of the slider assembly, which greatly reduces the friction between the sliding parts; the slider The application of components in the roll gap adjustment device can reduce the requirements for the driving mode in the device; the strip mill can realize real-time fine control of the roll gap during continuous production.

Description

technical field [0001] The invention relates to the technical field of strip rolling mills, in particular to a slider assembly, a roll gap adjusting device and a strip rolling mill. Background technique [0002] The strip mill is the equipment that realizes the metal rolling process. The rolling mill mainly includes the following mechanisms: rolls, rolling mill arches, bearing packages, bearings, worktables, rolling guides, rail seats, roll adjustment devices, upper roll balance devices and roll change devices. Among them, the roll adjustment device is used to adjust the roll gap so that the rolled piece can reach the required section size. [0003] There are three types of roller gap adjustment devices: manual, electric and hydraulic. The manual pressing device is mostly used in profile rolling mills and small rolling mills; the electric pressing device has high precision and convenient speed regulation, but the disadvantage is that its transmission efficiency is low, the...
