Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 , figure 2 As shown, the structure of the existing reversible cold rolling unit steering roll device is that a bearing 3 is respectively installed on the two ends of the steering roll 1, and each bearing 3 is connected by a respective bearing seat 2, end cover 4 and connecting fasteners. It is installed on the connecting bottom plate 8, and an encoder 6 is fixedly installed on the support 7 on the outer side of the end cover 4 of the bearing 3 on one side. The rotary shaft of the encoder 6 is coaxially connected with the steering roller 1 through the small shaft 5, and rotates synchronously. Realize indirect measurement of strip speed to meet the requirements of speed and AGC thickness control. In order to ensure the level of the steering roller 1 and the parallelism with related parts during on-site installation, i...

Abstract

The invention discloses a turning roll device of a reversible cold rolling mill unit. The turning roll device comprises two fixing bearing bases, the front edge of the lower end of each fixing bearing base is provided with a groove which is meshed and clamped with a step on a bottom plate, and the rear edge of the lower end of each fixing bearing base is provided with a positioning stopping block used for limiting. A combined piece of a turning roll and bearings at the two ends of the turning roll is mounted in an open groove in the upper portion of each fixing bearing base, and a gland bearing pedestal is buckled to the opening edge of the open groove in the upper portion of each fixing bearing pedestal. According to the turning roll device of the reversible cold rolling mill unit, the overall form of each bearing pedestal of the turning roll is changed to be of a split structure, the phenomenon that a large amount of time is consumed for dismounting, mounting and maintaining due to the fact that the device breaks down in the using process is avoided, the phenomenon that due to the difference of the technological levels of maintaining and mounting personnel, the mounting precision of equipment cannot meet the design requirement, so that the normal production of the unit is affected is also avoided, and maintaining and replacing can be achieved conveniently and quickly.

Description

technical field [0001] The invention belongs to the technical field of rolling equipment, and relates to a steering roll device of a reversible cold rolling unit. Background technique [0002] The steering rolls before and after the coiler in the reversing cold rolling unit in the rolling workshop are important auxiliary equipment. Their working status directly affects whether the strip can be rolled smoothly during the rolling process, without deviation and neatly coiled after rolling. The steering roller plays an important role in the rolling process and the coiling process of the strip. The steering roller realizes the change of the running direction of the strip and meets the requirements of the coiler for stable coiling; the end of the steering roller is equipped with an encoder The speed of the strip can be measured indirectly to meet the needs of speed and thickness control; the steering rollers on both sides of the rolling mill are parallel to the reel and roll axis ...
