Flattening roller

Technical Field

The utility model relates to a mechanical equipment technical field uses extensively in accurate stainless steel production line.

Background

The internal stress of the ultrathin stainless steel with the thickness of 0.02mm is released after the annealing of the bright lines, the situation that the plate types are different appears at each position of the steel strip after the releasing, the situation that the plate types are different is expressed in a wave form, and when the steel strip is longitudinally stretched, because the stress of the part with the wave and the part without the wave is different, the elastic deformation of the produced shape is also different, so that the condition of wrinkles can appear, and the wrinkle which cannot be eliminated can appear in serious cases. Moreover, the wave may appear at any position of the steel strip, while the convexity of the general flattening roll can only be located in the middle of the roll and cannot be adjusted, and if the wave position appears at the edge or other positions except the middle, the general flattening roll cannot be flattened, which brings great difficulty to the production of the ultrathin stainless steel. Therefore, the spiral mandrel type flattening roll is designed and invented, the convexity position of the flattening roll can be freely adjusted according to different rotation angles of the roll, the convexity direction of the flattening roll faces the wavy position of a steel strip, the steel strip can be well stretched, and the problem of wrinkles is solved.

Detailed Description

The invention aims to overcome the defects of a conventional arc-shaped flattening roller and provides a flattening roller of a spiral mandrel, which can adjust the position of convexity through adjusting the rotating angle of a mandrel 3 so as to deal with the wrinkle defects of various ultrathin stainless steels. The position of the wrinkles generated by different specifications of steel strips is different, so that the position of the convexity of the flattening roll is different. The general flattening roll can only spread the steel strip from the middle, and the general flattening roll can not cope with the condition that the steel strip wave is not in the middle or more than one wave. Therefore, the spiral mandrel 3 type flattening roller is designed, the flattening roller can realize the change of the convexity position of the roller only by rotating the angle of the mandrel 3, and therefore, the roller can deal with various complex wave conditions. The specific scheme is as follows:

the spiral mandrel 3 type flattening roller consists of a spiral mandrel 3, a rolling bearing, a bearing seat 1 and a rubber sleeve 2. The dabber 3 of 3 formula nip rolls of spiral dabber is helical structure, and 3 fixed 6 sets of bearings in dabber surface, fixed pivoted nylon sleeve between bearing and the bearing, the outside cladding bearing frame 1 of nylon sleeve. The bearing seat 1 is a rubber sleeve 2, the diameter of the spiral mandrel 3 is 50mm, the diameter of the spiral arc corresponding to a circle is 150mm, the spiral length is 850mm, and the number of turns is 1. Rotation of the helical mandrel 3 from 0 to 180 enables the convexity to change position steplessly. The angle of the mandrel 3 can be adjusted through an adjusting hole on the mandrel 3.

The principle of flattening the wrinkles is as follows: the position of the mandrel 3 is adjusted and then the mandrel is fixed, the rubber sleeve 2 rotates around the mandrel 3, the running direction of the roller surface convexity position of the flattening roller is parallel to the running direction of the steel belt after the wave position of the steel belt passes through the convexity position of the flattening roller, and the running directions of all points at the positions at two sides of the convexity form a certain angle with the running direction of the steel belt, so that the force to two sides is applied to the steel belt, and the wave of the steel belt can be unfolded.

The structural shape of the mandrel 3 and the position change of the convexity are shown in fig. 2. The roller is at the position of 0 degree, the convexity direction of the roller is positioned at the lowest part and corresponds to the lower edge wave of the steel belt; when the angle is 90 degrees, the convexity direction of the roller is positioned at the middle position and corresponds to the middle wave of the steel belt; at the 180-degree position, the convexity direction of the roller is positioned at the top and corresponds to the upper edge wave of the steel belt. The mandrel 3 rotates from 0 degrees to 180 degrees, and the convexity position can be adjusted in a stepless way.

The mandrel 3 is spiral, the diameter of the spiral arc corresponding to the circle is 150mm, and the number of turns is 1. The convexity position of the mandrel 3 changes along with the rotation of the mandrel 3 when viewed from the side, and can correspond to any position of the steel strip,

the bearing and the nylon sleeve are arranged on the mandrel 3, and the rubber sleeve 2 which is integrated is arranged outside the mandrel as the bearing seat 1. The rubber sleeve 2 is continuously deformed as the roller rotates, and the rubber sleeve 2 is preferably made of polyurethane lined internally with reinforcements, such as fibers.

Bearing seats 1 are installed at two ends of the mandrel 3, and the mandrel 3 is fixed inside the bearing seats 1 through nylon sleeves. In the fastened state of the bearing seat 1, the mandrel 3 is fixed. The angle of the bearing seat 1 can be adjusted through an adjusting hole in the mandrel 3 after the bearing seat is opened.

The whole flattening roll comprises two bearing blocks 1, a mandrel 3 and a roll body. The two bearing blocks 1 are installation parts and are connected with the frame through bolts.

The flattening roll can be arranged at the positions which are easy to generate folds, such as the front part of the guide roll, the front part of the pinch roll, the front part of the rectification roll and the like, and can effectively extend and unfold the waves of the ultrathin stainless steel.

As shown in figure 2, the angles of the mandrels 3 are different, and the convexity can be adjusted at will to deal with various complex conditions. The following table shows the general specification wave service conditions:

the flattening roll is put into use on a vertical bright annealing line from 2018 and 9 months, the problem of wrinkles of various plate-type steel strips can be perfectly solved, and products are accepted by customers.

The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
