Machining device and method of high-precision intaglio roller

Abstract

The invention relates to a machining device of a high-precision intaglio roller. The machining device is used for roughly turning the external circle of a steel pipe to be machined, the steel pipe tobe machined is used for manufacturing the intaglio roller, the machining device of the high-precision intaglio roller comprises a lathe and mandrel, the mandrel is detachably connected with the lathe,the lathe is used for supporting the mandrel and driving the mandrel to rotate, and the mandrel is matched with the steel pipe to be machined and used for supporting the inside of the steel pipe to be machined. When the external circle rough turning process is carried out, the steel pipe to be machined is mounted on the mandrel, the mandrel tightly supports the inside of the steel pipe to be machined, the lathe is started, the mandrel is driven to rotate, and external circle rough turning is carried out. Compared with the prior art, the result of roughly turning the external circle is more accurate, the steel pipe with the smooth external circle of the pipe wall and more uniform thickness of the pipe wall can be obtained, complicated dynamic balance detection, counterweight and re-detection procedures in the machining process of the high-precision intaglio roller can be omitted, the production cost is reduced, and the production time is shortened.

Description

technical field [0001] The invention relates to the field of gravure plate roll processing, in particular to a high-precision gravure plate roll processing device and method. Background technique [0002] The material of the gravure plate substrate is generally seamless steel pipe, and a few are made of aluminum. Because the price of steel pipes is low and firm, most of them use steel pipes, with a weight ranging from 10 kg (narrow and small printing machines) to hundreds of kilograms (wide and large printing machines, monochrome gravure printing press). The wall thickness of the steel pipe is from 6mm to 30mm, and the large size roller is thicker. The wall thickness of the steel pipe is from 6mm to 30mm, and the large size roller is thicker. According to the needs of printing machines, printing plates are divided into shaftless and shafted. Generally, small flexible packaging printing machines use shaftless hollow printing plates, and large printing machines use shaft pri...

AI Technical Summary

Problems solved by technology

[0011] 1) Although the dynamic balance process in the above processing can make the rotation of the plate roll stable, the problem of uneven wall thickness of the plate roll cannot be solved. If the process is carried out by boring the inner hole, the inner hole of the steel pipe needs to be processed The margin, the material consumption is large, the processing time is long, and the production cost of the plate roller is increased

[0012] 2) During the dynamic balancing process, the welding of the balance weight and balance block should be carried out, which will cause deformation of the plate roller
