Mechanical production process for series large high-velocity roller

Abstract

The invention relates to a production process for a series large high-velocity roller. The production process comprises a roller disassembling production process, material selection and production processes of parts and a roller assembling machining process. Firstly, a roller is disassembled to five parts such as left and right supporting shafts, left and right end covers and a roller body, the five parts are respectively independently subjected to semi-finishing and then combined to be machined, the left and right supporting shafts and the left and right end covers are combined to form left and right bearings, then the left and right bearings and the roller body are assembled to form the roller, and finally, whole finish machining, dynamic balance, finishing cut and final heat-treatment are performed. The mechanical production process for the series large high-velocity roller is suitable for series large roller machining, production qualities can be guaranteed, requirements for large scale equipment are reduced, and the producing costs are low.

Description

technical field [0001] The invention relates to a series of large-scale high-speed rollers, in particular to a mechanical manufacturing process for large-scale high-speed rollers used for ink rolling and embossing. Background technique [0002] Printing machinery is developing towards high-speed, fully automated production lines. The large high-speed roller is an important part of the high-speed printing machine. The printing template installed on the high-speed roller is in contact with the printing cardboard, and the ink is imprinted on the surface of the printing cardboard according to the shape of the printing template, thereby printing various patterns. . The surface finish, geometric accuracy, and rotation accuracy of high-speed rollers have an important impact on the quality of printed matter. The existing low-speed roller manufacturing process is difficult to meet the rotation accuracy and stability requirements of high-speed rollers. The large-scale high-speed rol...

AI Technical Summary

Problems solved by technology

The existing low-speed roller manufacturing process is difficult to meet the rotation accuracy and stability requirements of high-speed rollers. The large-scale high-speed roller manufacturing process must not only ensure its manufacturing quality, but also ensure its high-speed rotation accuracy and stability. At the same time, consider Its manufacturing cost, production efficiency and labor intensity of workers
