Pattern roller manufacturing method

Abstract

The invention relates to a method for manufacturing a patterned roll, which comprises the following steps: 1) selecting a suitable cold rolling roll material according to the hardness of a rolled patterned metal plate; 2) making a roll blank according to a conventional process; 3) making the roll blank 4) heat-treat the roll blank to make its hardness meet the rolling pattern requirements; 5) carry out surface pretreatment according to the size required by the roll; 6) heat-treat the roll surface Laser strengthening treatment; 7) Carry out pattern electric machining and forming treatment on the surface of the roll. The invention uses water-based quenching liquid for heat treatment, so that the quality and size requirements of the finished roll can be guaranteed as long as there is a small processing allowance for the roll blank, thereby achieving the purpose of reducing product costs; after laser surface strengthening treatment, the roll The hardness of the roll body is also improved, which improves the service life of the product. The number of times each pair of rolls are used on the machine is increased from 7-8 times to 14-15 times.

Description

technical field [0001] The invention relates to a method for manufacturing a patterned roll. Background technique [0002] At present, patterned rolls are usually made of ordinary steel materials. In order to improve the working hardness and wear resistance of patterned rolls, heat treatment is carried out. However, in the existing heat treatment, it is usually necessary to leave a large amount of processing allowance for the roll blank. , otherwise the size of the product cannot be guaranteed, which will lead to an increase in the processing cost of the product. In addition, when a large machining allowance is left, the product after heat treatment needs to be machined twice, so that the quenched layer on the surface of the product becomes thinner, making it difficult to Meet people's use requirements. Contents of the invention [0003] For the problems existing in the prior art, the object of the present invention is to provide a technical scheme of a manufacturing meth...
