Embodiment 1

[0024] Embodiment 1: a kind of manufacturing method of version roller, comprises the steps:

[0025] (1) Production of plate roller base: it is processed by seamless steel pipe;

[0026] Among them, in terms of mass percentage, the formula of the seamless steel pipe is: C: 0.01%; Si: 0.50%; Mn: 0.02%; S: 0.005%; P: 0.005%; Cr: 21.00%; : 0.35%; N: 0.01%; Ti: 0.03%; the balance is Fe and unavoidable impurities;

[0027] (2) Copper plating treatment on the base of the version roller: place the base of the version roller in an electroplating tank equipped with a copper plating solution for copper plating, and the thickness of the copper layer plated is 15-18 μm;

[0028] Among them, the copper plating solution includes 8g / l CuSO 4 , 0.8g / l Na 2 SO 3 , 0.5g / l complexing agent, 0.3g / l NaCl and 0.02g / l PAA, and the pH of the copper plating solution is 11.0-11.5;

[0029] (3) Surface treatment of plate roller after copper plating: grinding the copper surface;

[0030] (4) Glue c...

Embodiment 2

[0035] Example 2: A method of manufacturing a plate roll, the difference from Example 1 is that the formula of the seamless steel pipe is: C: 0.02wt%; Si: 0.72wt%; Mn: 0.04wt%; S: 0.01 Wt%; P: 0.01wt%; Cr: 20.00wt%; Ni: 8.00wt%; Cu: 0.30wt%; N: 0.02wt%;

Embodiment 3

[0036] Example 3: A method of manufacturing a plate roll, the difference from Example 1 is that the formula of the seamless steel pipe is: C: 0.02wt%; Si: 0.72wt%; Mn: 0.04wt%; S: 0.01 Wt%; P: 0.01wt%; Cr: 22.00wt%; Ni: 9.25wt%; Cu: 0.40wt%; N: 0.02wt%;

Abstract

The invention discloses a manufacturing method of a plate roller. The manufacturing method comprises the following steps: a plate roller base is manufactured and is formed by machining a seamless steel pipe according to a specific formula; the plate roller base is subjected to copper plating treatment in an electroplating bath containing specific copper plating liquid and the thickness of a copper layer is 15-18 micrometers; plate roller surface treatment is carried out after copper plating since rinding treatment is carried out on a cooper surface; gluing of the plate roller is carried out since the plate roller after the copper plating and the surface treatment is coated with a layer of 0.10-0.15mm thick glue solution and air drying treatment is carried out; laser image document manufacturing, laser engraving manufacturing of the plate roller and development of the plate roller are carried out; corrosion of the plate roller is carried out since spraying type corrosion treatment is carried out with special corrosive liquid; cleaning of plate roller is carried out since spraying type cleaning treatment is carried out with specific cleaning liquid; and chromium plating of the plate roller is carried out since chromium plating treatment is carried out in an electroplating bath containing specific chromium plating liquid and the thickness of a chromium layer is 5-8 micrometers. The manufacturing method has the advantage of reducing the differences of surface flatness of different parts of the same plate roller.

Description

technical field [0001] The invention relates to plate roll technology, in particular to a method for making plate roll. Background technique [0002] Plate rolls, also known as steel rolls, are generally used for plate making. Commonly used version rollers are copper-plated on the surface of the cylinder, engraved with a gravure electronic engraving machine, and then plated with a layer of chrome. The completed plate roll is often used for printing on plastic packaging. [0003] The Chinese patent application published as CN103481638A and published on January 1, 2014 discloses a master roll for laser paper printing and its manufacturing process, which includes copper plating, encapsulation, laser engraving, corrosion, degumming and Chrome finish. In these processes, the surface of the plate roll is treated multiple times, and the degree of reaction of the plate roll is different, resulting in a large difference in the surface smoothness of different parts on the same plat...
