The utility model aims to overcome the defects in the prior art and provide a roller for bimetal composite rolling, the stress of the aluminum alloy after the composite is finished is changed from the original unidirectional stress to the bidirectional stress, and a composite belt is not easy to be adhered to the roller; the service life of the working roll is prolonged, the replacement and adjustment frequency is greatly reduced, the roll replacement difficulty is reduced, and the effective production time is greatly prolonged; the number of the working roller is changed from four to two, so that the production investment is reduced; the subsequent grinding and repairing processes are reduced, and the production cost of the product is reduced.
In order to achieve the purpose, the technical scheme of the utility model is to design a roller for bimetal composite rolling, which comprises a pair of opposite rollers, namely an upper roller and a lower roller, wherein the pair of opposite rollers are provided with a ring groove for ensuring the width dimension of a bimetal composite strip and avoiding the generation of flash, the rotation axis of the ring groove is parallel to the rotation axis of the lower roller, and the cross section of the ring groove is rectangular or U-shaped. The width of the upper roller is the same as that of the lower roller; the concave ring grooves are formed in the surfaces of the rollers, so that a customized concave space is formed on the contact surfaces of the two rollers and used for rolling the bimetal composite plate strip, and the problems that four rollers are adopted, namely two pairs of rollers are easy to generate flash in the width direction, burrs are easy to generate at the bottom corners, and the width dimension is not easy to guarantee are solved.
The further technical scheme is that the upper roller and the lower roller are both provided with ring grooves, the ring grooves are formed in the outer surface of the middle of the roller surface, and the ring grooves of the upper roller and the ring grooves of the lower roller are matched to form a space for bimetal composite rolling. The upper and lower rollers are provided with circular grooves with U-shaped sections (or circular grooves with rectangular sections), so that the aluminum alloy parts are uniformly distributed in the upper and lower rollers from top to bottom, when the rollers rotate, the stress of the aluminum alloy parts after compounding is changed from the original unidirectional stress into bidirectional stress, the composite plate strip is not easy to be adhered to the rollers, and the composite strip can be easily pulled out by proper front tension.
The technical scheme is that the middle outer surface in the width direction of the lower roller is provided with an annular positioning part protruding outwards, the middle outer surface in the width direction of the upper roller is provided with a positioning groove matched with the annular positioning part, the groove bottom wall of the positioning groove is provided with the annular groove, and the middle part of the annular positioning part is also provided with the annular groove. After the arrangement, the upper ring groove and the lower ring groove (namely the ring groove on the upper roller and the ring groove on the lower roller) are aligned and level with each other by positioning the rollers, the positioning part and the positioning groove are arranged to play a positioning role, and the defects of flash, burr and the like can be avoided. The upper and lower working rolls are used in pairs, and the edge parts are provided with positioning parts, so that the side surfaces of the upper and lower U-shaped grooves (ring grooves) can be aligned.
The further technical scheme is that the roller for bimetal composite rolling is used for rolling the aluminum alloy stainless steel composite plate strip, the groove depth of the ring groove in the upper roller is half of the thickness of the aluminum alloy raw material plate, and the sum of the half thickness of the aluminum alloy raw material plate and the thickness of the stainless steel raw material plate is equal to the groove depth of the ring groove in the lower roller. The arrangement of the groove depth enables the central line position of the aluminum alloy in the compounded plate strip to be flush with the roll surfaces of the upper working roll and the lower working roll; (after the composite strip is taken out of the rolls, the aluminum alloy parts are evenly adhered to the upper and lower rolls, and are separated along with the rotation of the rolls, so that the requirement on the outlet tension is reduced).
The other technical scheme is that the lower roller is provided with a ring groove which is arranged on the outer surface of the middle part of the roller surface of the lower roller. Compared with four-roller rolling, the mode can avoid flash, but the rolling mode has large total deformation of aluminum alloy and large rolling pressure, the aluminum alloy metal is easy to adhere to the roller, the rolled composite strip can adhere to the roller and cannot be separated from the roller < the normal maximum outlet tension is far less than the adhesion force (friction force and side steel-aluminum adhesion separation force) of the composite strip and the roller >, and when the outlet tension is increased, the composite strip is easy to break. Therefore, the more preferable solution is the last solution.
The utility model has the advantages and beneficial effects that: the service life of the working roll is prolonged, the replacement and adjustment frequency is greatly reduced, the roll replacement difficulty is reduced, and the effective production time is greatly prolonged; the number of the working roller is changed from four to two, so that the production investment is reduced; the subsequent grinding and repairing processes are reduced, and the production cost of the product is reduced. The upper and lower rollers are provided with circular grooves with U-shaped sections (or circular grooves with rectangular sections), so that the aluminum alloy parts are uniformly distributed in the upper and lower rollers from top to bottom, when the rollers rotate, the stress of the aluminum alloy parts after compounding is changed from the original unidirectional stress into bidirectional stress, the composite plate strip is not easy to be adhered to the rollers, and the composite strip can be easily pulled out by proper front tension. Make things convenient for the location of roll to guarantee the parallel and level of upper and lower annular (also annular on the upper roll and the annular on the lower roll) to location portion and positioning groove's setting play the positioning action, can also avoid producing defects such as overlap burr. The upper and lower working rolls are used in pairs, and the edge parts are provided with positioning parts, so that the side surfaces of the upper and lower U-shaped grooves (ring grooves) can be aligned. The arrangement of the groove depth enables the central line position of the aluminum alloy in the compounded plate strip to be flush with the roll surfaces of the upper working roll and the lower working roll; (after the composite strip is taken out of the rolls, the aluminum alloy parts are evenly adhered to the upper and lower rolls, and are separated along with the rotation of the rolls, so that the requirement on the outlet tension is reduced).
