Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] A series of large high-speed rollers ( figure 1 ) manufacturing process, including roller split manufacturing process, parts material selection and manufacturing process, roller assembly and processing technology.

[0027] Roller split manufacturing process is to split the roller into left and right support shafts 1, 5, left and right end covers 2, 4 and cylinder body 3 five components ( figure 1 ), the five parts are separately semi-finishing and then combined and then processed. First, the left and right support shafts 1, 5 and the left and right end covers 2, 4 are respectively combined into left and right supports ( Figure 5 , Image 6 ) and finish machining, and then assemble the left and right supports with the cylinder body 3 to form a roller ( figure 1 ), and then carry out overall finishing, dynamic balancing, finishing and final hea...

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...
