Embodiment 1

[0020] In order to solve the problem that the rollers on the skin pass machine cause the strip on the rollers to vibrate when they move, causing the strip to wrinkle, and even cause uneven deformation of the galvanized sheet during skin skinning, resulting in local yield and slip lines on the surface after skin skinning Useless belt, what's more, causes broken belt, damages the problem of the work roll surface of the skin pass machine, the present embodiment provides such as figure 1 A chute-type anti-wrinkle roller device shown includes two opposite brackets 6, on which a chute 5 is installed, and a movable frame 2 is installed in the chute 5, and the movable frame 2 goes up and down along the chute 5 Sliding, hydraulic components are connected to the movable frame 2; the roller 1 is connected between the two movable frames 2.

[0021] The working process of this embodiment is:

[0022] The hydraulic component pushes the movable frame 2 to slide up and down along the chute 5...

Embodiment 2

[0026] On the basis of Embodiment 1, the hydraulic component is a hydraulic cylinder 7 , the head of the hydraulic cylinder 7 is fixedly connected to the upper end of the movable frame 2 , and the tail of the hydraulic cylinder 7 is connected to the lower end of the chute 5 .

[0027] Because the hydraulic cylinder 7 is fixedly connected with the movable frame 2, the hydraulic cylinder 7 will also promote the movable frame 2 to slide and lift along the chute 5 when the hydraulic cylinder 7 lifts, and the movable frame 2 drives the rollers to lift, so that the strip on the roller 1 (plated Zinc plate) has a uniform distribution of tensile stress in the width direction, which overcomes the problems of uneven deformation, local yield and broken strip on the strip surface.

Embodiment 3

[0029] On the basis of embodiment 1 or 2, such as figure 2 As shown, the chute type anti-wrinkle roller device also includes a shaft 14 and two shaft seats 10, the two ends of the shaft 14 are installed in the shaft seats 10, and there is a sleeve between the shaft seats 10 and the shaft 14. On the shaft sleeve 11, the shaft sleeve 11 is fixedly connected with the chute 5 through screws, and two gears 12 are symmetrically installed on the shaft 14;

[0030] A rack 13 is fixedly installed on the two movable frames 2 , and the rack 13 is arranged parallel to the axial centerline of the hydraulic cylinder 7 , and the rack 13 meshes with the gear 12 .

[0031] When the hydraulic cylinder 7 pushes the movable frame 2 up, there may be asynchronous rise, so that the surface of the roller 1 cannot contact the strip at the same time, resulting in some wrinkling problems on the strip on the roller 1, and in order to completely eliminate For this kind of wrinkling, the present embodime...

Abstract

The invention provides a sliding groove type crease-resistant roller device. The sliding groove type crease-resistant roller device comprises two oppositely arranged supports which are each provided with a sliding groove; a movable frame is installed in each sliding groove and slides up and down along the sliding groove; a hydraulic assembly is connected to each movable frame; and a roller is connected between the two movable frames. According to the sliding groove type crease-resistant roller device, the movable frames slide and run in the sliding grooves, the movable frames do not exceed the sliding grooves under the maximum stroke, so that the movable frames can steadily run, and therefore it is guaranteed that a strip material does not shake when the roller acts; racks and gears are in engagement transmission, it is guaranteed that the two ends of the roller run synchronously and make contact with the strip material at the same time, and the crease-resistant function is achieved; and hydraulic cylinders are installed on the inner side and each provided with a safety pin shaft, maintenance is convenient, and the structure is light and easy to implement.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a chute-type anti-wrinkle roller device and its use method and application. Background technique [0002] In the field of metallurgical equipment, especially metal strip finishing and processing units (such as hot-dip galvanizing units), when the galvanized sheet passes through the skin-passing machine, the galvanized sheet is under the action of high finishing force and large tension. Due to the fluctuation of production line speed and Due to reasons such as plate shape, when the galvanized sheet passes through the skin pass machine, the rollers on the skin pass machine will cause the galvanized sheet to vibrate, wrinkle, uneven tensile stress, and even the entrance tension disappears, resulting in uneven deformation of the galvanized sheet during skin pass. Uniformity, partial yielding, slip lines appear on the surface after skin skinning, resulting in waste belts, what is mor...
