Compared with the prior art, the process of the invention is greatly simplified; the anilox roller has light weight, low manufacture cost, is convenient for disassembly and cleaning, contains no metals of copper or chromium of plating process with pollution, and belongs to the environmental protection technique.
Description
Technical field
The present invention relates to a kind of inking device of flexographic presses, particularly relate to anilox roll and the technology of making this anilox roll on the inking device.
Background technology
Anilox roll of the prior art has two kinds, and a kind of is traditional copper anilox roll, and another kind is the laser ceramics anilox roll.
(1) traditional copper anilox roll: material is steel roller faces copper facing, and with electronics graver engraving reticulate pattern, last chromium plating improves wearability again.Just there are two problems in this: the one, and anilox roll is very heavy, mounting or dismounting when being not easy to clean; Two have been to use electro-coppering, chromium process, the not environmental protection of the electroplating technology utmost point, show according to interrelated data, the chromium that the plating raw material is used is Cr VI, suck and to make pneumosclerosis, pulmonary emphysema behind the human body, feel sick etc., and hexavalent chromium compound is a carcinogen, and plating baths such as copper, hydrochloric acid, sulfuric acid, sodium hydroxid all can cause various diseases to the people.
(2) conventional laser ceramic anilox roller: be to spray one deck pottery, carve reticulate pattern with laser carving method at ceramic surface again in steel roller faces.This laser carving method cost is higher, and very heavy.
Summary of the invention
First technical problem to be solved by this invention is: a kind of anilox roll is provided, and this anilox roll adopts the aluminium and the aluminium alloy of lightweight, does not contain existing copper, chromium metal with contaminative.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: comprise the roller top layer, described roller top layer material is an aluminum or aluminum alloy, and the Surface Machining on the roller top layer has reticulate pattern, and net grain surface is with one deck oxide ceramic layer.
Preferably: described reticulate pattern is made of the ink cell unit, and the cross sectional shape of described ink cell unit is arbitrary shape in helical teeth shape, pyramid, terrace with edge shape, bowl-type or the test tube shaped.
Preferably: described aluminium alloy is an almag.
Second technical problem to be solved by this invention is: the manufacturing process of above-mentioned anilox roll is provided, and this manufacturing process can be used for making the anilox roll of the aluminiferous metals of lightweight, and this anilox roll does not contain existing copper, chromium metal with electroplating technology of contaminative.
In order to solve above-mentioned second technical problem, the present invention adopts following technical scheme: be used to make the manufacturing process of described anilox roll, may further comprise the steps:
Steps A: labor and materials are processed into semi-finished product roll body to be carved;
Step B: reticulate pattern processing is carried out by the electronic engraving method in the surface at the semi-finished product roll body, and the semi-finished product roll body is processed into anilox roll;
Step C: differential arc oxidation is carried out on the anilox roll surface handle, make its surface generate the metal oxide ceramic layer that one deck has wearability.
Preferably: differential arc oxidation among the described step C is handled and is comprised: in alkaline electrolyte, make the surface of anilox roll grow the ceramic layer of layer of metal autoxidation thing under the high-frequency impulse electric field action.Differential arc oxidation is handled and can be generated the technology that one deck oxide ceramic layer and processing procedure do not have the restricted element of environmental protection on the almag surface.This technology can effectively prevent galvanic corrosion and the unexpected frettage between the atmospheric corrosion of almag, the connection of different metal, has greatly improved the aluminium alloy resistance to corrosion and has improved the metal surface abrasive resistance.
The invention has the beneficial effects as follows: the anilox roll that the present invention makes adopts the aluminium of lightweight, does not contain copper, the chromium metal of contaminated environment, helps the production environment that keeps good; Also saved electro-coppering, electrodeposited chromium technology compared to existing technology, its work simplification is a lot; This anilox roll light weight, low cost of manufacture, cleaning also for convenience detach.
The present invention is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is an anilox roll surface structure schematic diagram of the present invention.
The specific embodiment
The invention provides a kind of anilox roll, roll body comprises the roller top layer.The material on roller top layer 1 is an aluminum or aluminum alloy, is preferably almag.Referring to Fig. 1, in the Surface Machining of roll body 1 reticulate pattern 2 is arranged, reticulate pattern 2 surfaces are with one deck oxide ceramic layer 3.
The shape of the ink cell unit of reticulate pattern is seen as helical teeth shape from sectional area.Also can be other shapes such as pyramid, terrace with edge shape, bowl-type or test tube shaped.
In order to make above-mentioned anilox roll the present invention a kind of manufacturing process of making this anilox roll is proposed also.This manufacturing process is as follows.
Steps A: labor and materials are processed into semi-finished product roll body to be carved;
Step B: reticulate pattern processing is carried out by the electronic engraving method in the surface at the semi-finished product roll body, becomes anilox roll;
Step C: differential arc oxidation is carried out on the anilox roll surface handle, make its surface generate the metal oxide ceramic layer that one deck has wearability.
Wherein step B is included in the cutting fluid that is used for reducing sticking cutter in the engraving process in the processing reticulate pattern process simultaneously.Because the electronic engraving cutter is suitable for carving hardness most at the HV170-190 material, and the hardness ratio of aluminium or aluminium alloy engraving hardness is low, might be because viscous force effect meeting produces sticking cutter phenomenon in the engraving process.In order to solve sticking cutter problem in the electronic engraving process, can take in processing reticulate pattern process, to follow and use cutting fluid to fall engraving viscous force technology, change satisfactory cutting fluid and solve sticking cutter problem.Perhaps in the alloy aluminium, change the content of alloying component, suitably improve the way of alloy aluminium hardness.
Differential arc oxidation among the step C is handled and is comprised: in alkaline electrolyte, make the surface of anilox roll grow the ceramic layer of layer of metal autoxidation thing under the high-frequency impulse electric field action.Because the shape of ink cell unit has various ways such as helical teeth shape, pyramid, terrace with edge shape, the different ink cell opening degrees of screen density are also different with the degree of depth, might be after the ceramic treatment technology, the hardness of ceramic layer, the possible inconsistent problem of uniformity can adopt differential arc oxidation to handle in the ink cell.
Differential arc oxidation is handled can not have the restricted element intervention of environmental protection in aluminium, Mg alloy surface generation one deck oxide ceramic layer and processing procedure.This technology has effectively prevented galvanic corrosion and the unexpected frettage between the atmospheric corrosion of magnesium alloy, the connection of different metal, has greatly improved aluminium alloy resistance to corrosion, high temperature heat etching and surface abrasion resistance ability.
Anilox roll surface ceramic deposition treatment technology is to take in alkaline electrolyte, makes its surface grow the ceramic layer of layer of metal autoxidation thing under the high-frequency impulse electric field action.In processing procedure, can take to adjust concentration, temperature and the processing time of electrolyte, guarantee its hardness, uniformity unanimity.
