Embodiment 1

[0024] Such as figure 1 with figure 2 As shown, the present invention provides a double eccentric and convex traverse roll for a twenty-high rolling mill, comprising a mandrel 7, one end of which is sleeved with a large eccentricity shaft sleeve 2, and the other end is sleeved A small eccentricity shaft sleeve 10 is provided, a large eccentricity shaft sleeve 2 and a small eccentricity shaft sleeve 10 are provided with a roller 8 sleeved on the mandrel 7 with a protrusion 802 in the middle, the large eccentricity shaft sleeve A joint bearing 4 is provided between the inner wall of 2 and the inner wall of the small eccentricity sleeve 10 and the spindle 7. The joint bearing 4 is provided with a distance ring 5 at one end close to the roller 8 and a press buckle 3 at the end far away from the roller 8 , The joint bearing 4, the press buckle 3, and the distance ring 5 are all sleeved on the mandrel 7 and can slide along the inner wall of the large eccentricity sleeve 2 or the sma...

Embodiment 2

[0039] On the basis of Example 1, in particular, in order to prevent the belt deviation from not being detected and adjusted in time, the belt will be quickly clipped into the rotating equipment and be torn. The present invention provides protective measures, namely Both ends of the roller 8 are respectively provided with ribs 801 coaxial with the roller 8, the outer diameter of the rib 801 is larger than the outer diameter of the roller 8, which effectively prevents the belt from being clamped into the equipment.

Embodiment 3

[0041] On the basis of embodiment 1, further, the protrusion 802 is located on the outer surface of the roller 8, and the protrusion 802 is symmetrical with respect to the radial centerline of the roller 8. Specifically, the outer surface of the roller 8 has a certain shape. The convexity is symmetrical with respect to the center of the width direction of the roller 8. The belt is bent to a certain extent on the outer surface of the roller 8, which increases the contact range and lateral friction to prevent the belt from deviating.

Abstract

The invention provides a double-eccentric bulged cross-sliding type wrapper roll for a twenty-high rolling mill. The wrapper roll comprises a mandrel, wherein one end of the mandrel is sleeved with a large-eccentricity shaft sleeve, the other end of the mandrel is sleeved with a small-eccentricity shaft sleeve, a roller which is arranged on the mandrel in a sleeving manner and is provided with a bulge at the middle part is arranged between the large-eccentricity shaft sleeve and the small-eccentricity shaft sleeve, joint bearings are respectively arranged between the inner walls of the large-eccentricity shaft sleeve and the small-eccentricity shaft sleeve and the mandrel, one end, close to the roller, of each joint bearing is provided with a distance ring, one end, away from the roller, of the joint bearing is provided with a pressing buckle, and the joint bearings, the pressing buckles and the distance rings are all arranged on the mandrel in a sleeving manner and can slide on the inner wall of the large-eccentricity shaft sleeve or the small-eccentricity shaft sleeve; and two rolling bearings arranged on the mandrel in a sleeving manner are arranged between the roller and the mandrel, and the two end parts of the mandrel are respectively provided with a nut. By rotating the nuts, the mandrel and the roller are driven to horizontally move so as to adjust the horizontal distance between the wrapper roll and a centerline of a unit, so that the double-eccentric bulged cross-sliding type wrapper roll has the characteristics of wide contact range, various adjustment means, high production efficiency, and the like; and the wrapper roll is simple in structure and easy to operate and maintain.

Description

Technical field [0001] The invention belongs to the technical field of 20-high rolling mill production equipment, and specifically relates to a double-eccentric traverse type roll with crown of a 20-high rolling mill. Background technique [0002] The products of the 20-high mill are mostly high-precision extremely thin strips, and the jaws of the traditional coiler cannot clamp and coil the strips of this specification. Therefore, the 20-high mill must be equipped with a belt coiler to ensure the steel The coiling quality of the belt and the production efficiency of the unit. The belt coiler wraps the strip on the coiler drum through the coiling belt, and the strip rotates with the drum for several times before rolling with high tension. [0003] Regardless of whether the vertical belt winder or the horizontal belt winder, the common problem is that the belt deviation cannot be effectively adjusted. Due to the existence of objective reasons such as processing accuracy, installat...
