Description
Technical field
The invention belongs to new material modular construction and manufacture method thereof that a kind of color packing paper case printing and die-cutting machine is used, is a kind of reticulated duct and manufacture method thereof specifically, is mainly used in the color packing paper case printing and die-cutting machine.
Background technology
Reticulated duct is the critical component in the color packing paper case printing and die-cutting machine, and every printing and die-cutting machine needs 4 reticulated ducts, and reticulated duct is the consumptive material series products.Therefore the market of reticulated duct is big, and prospect is very wide.At present, reticulated duct is mainly based on traditional metal reticulated duct, and traditional metal reticulated duct anti-wear performance is poor, and service life is short, has only usually about 10 days, does not therefore satisfy the requirement of current high-speed color Packaging Box printing and die-cutting machine.Improve traditional metal reticulated duct in recently external (as the U.S., Japan, Europe), promptly adopt and carry out alumina ceramic coating on the metal tube surface and prepare reticulated duct, though its anti-wear performance of this way has certain improvement, though the ceramic coating reticulated duct improves than metal reticulated duct anti-wear performance, but because alumina ceramic coating and the difference of base material on thermal coefficient of expansion and elastic modelling quantity, the internal stress that exists causes fine crack can occurring in the use, thereby also can influence printing quality, shortened service life, be generally one month to two months.And domesticly oneself can't produce this ceramic coating reticulated duct, and almost all from external import, and costing an arm and a leg, its average price reaches 7000 yuan/part.Therefore necessary this is improved.
Summary of the invention
The objective of the invention is to: at the deficiency of existing color packing paper case printing machine reticulated duct, develop that a kind of wearability is better, long service life, and the low new type colorful Packaging Box printing and die-cutting machine reticulated duct of cost.
Another object of the present invention is to provide a kind of manufacture method of above-mentioned color packing paper case printing and die-cutting machine reticulated duct.
The objective of the invention is to be achieved through the following technical solutions: a kind of color packing paper case printing and die-cutting machine reticulated duct is characterized in that described reticulated duct is a ceramic overlapping curved pipe.According to the requirement of reticulated duct to material wear ability, intensity, toughness, to consider simultaneously to reduce manufacturing cost, described ceramic overlapping curved pipe is that selective oxidation zirconium reinforced alumina ceramic material prepares ceramic overlapping curved pipe, is the toughness reinforcing Al2O3 complex phase ceramic of ZrO2; Its weight and cost are lower than zirconia ceramics, but its wearability and strength and toughness that the ratio aluminum oxide ceramic coating will be good again is many.Product three-point bending strength 〉=500-600MPa of the present invention; Fracture toughness 〉=6.8-10MPa.m 1/2, hardness (Hv) 〉=1200-1500GPa.
Making of the present invention adopts gel injection molding and forming technology to prepare ceramic overlapping curved pipe, and method is simple and feasible; But consider that ceramic anilox pipe size is bigger, ftracture when avoiding binder removal, introduce intensity and the elastic modelling quantity that the stress sustained release agent is regulated gel network structure during moulding, cause the product distortion because of rate of drying control is improper when avoiding drying and crack, a kind of new drying means is proposed, promptly place the base substrate behind the shaping and demoulding polyethylene glycol aqueous solution to carry out drying, test shows that this is a kind of effective method.Be similarly when guaranteeing ceramic anilox pipe sintering and do not produce distortion, adopt vertical sintering (comprise and hang burning) technology, effect is obvious.Described ceramic overlapping curved pipe manufacturing process flow is:
The toughness reinforcing Al2O3 complex phase ceramic of ZrO2 powder preparation-→ ball milling-→ stir mill (introduce dispersant, pH value is regulated) produce high solid phase ceramic size-→ gel injection-moulding-→ drying-→ sintering-→ attrition process-→ the high-precision ceramic reticulated duct.
Wherein, the toughness reinforcing Al2O3 complex phase ceramic of described ZrO2 powder preparation is that zirconia powder and alumina powder are mixed (or according to 100 parts of zirconia powders: 20-80 part alumina powder carries out proportioning) according to any than row;
Described ball milling is with the zirconia powder and the alumina powder compound puts into ball mill and mixer is pulverized;
Described stirring grinds and gets high solid phase ceramic size is zirconia powder after pulverizing and alumina powder compound to be inserted in the mixer stir according to 100 parts of compounds adding 30-50 part water, and add: the dispersant of the general ceramic usefulness of 0.5-1 part according to 100 parts of compounds, carry out the pH value simultaneously and regulate, the pH value is between 5-6.Thereby prepare the complex phase ceramic suspended substance that solid concentration reaches 55vol%;
Described gel injection-moulding is that high solid phase ceramic size is injected metal die or the mould of plastics moulding that does not contain pore;
Described drying is that the water content ceramic body that casting solidifies is carried out drying in poly-hexylene glycol solution;
Described sintering is that dried casting ceramic body is placed shuttle kiln high temperature sintering kiln sintering;
Described attrition process is that the base substrate that will sinter is placed on garden attrition process outside the interior garden of carrying out the ceramic anilox pipe on the abrasive working appts.
The invention has the advantages that: in view of the reticulated duct size is bigger, general external diameter is 200-280mm, and length is 1.6-2.2mm, and thickness is bigger; Therefore adopt the gel casting forming technology, technology is easy, flexibility and reliability.
For the thick cross section of the large scale ceramic product of avoiding gel casting forming in drying or skimming processes because of defectives such as stress concentration crack, can introduce a small amount of stress sustained release agent, or in the poly-hexylene glycol aqueous solution, carry out drying, thereby can effectively solve the crack problem of ceramic anilox pipe body.
Adopt the gel casting forming technology of comparative maturity, technology is easy, and manufacturing cost is lower.Because this product size is big, for avoiding the molding blank season cracking; In the poly-hexylene glycol aqueous solution, carry out drying, thereby effectively solve the scasoning check problem of ceramic anilox pipe body.Usually general employing of gel casting forming product dried in the shade or heat drying, because unbalanced stress is even, causes large-size ceramic product cracking easily.For defective such as avoiding cracking in the binder removal process, introduce a small amount of stress sustained release agent in the molding blank, regulate the intensity and the elastic modelling quantity of organic monomer polymerization crosslinking network structure, effect is obvious.
This project adopts the toughness reinforcing Al2O3 complex phase ceramic of ZrO2 to prepare ceramic overlapping curved pipe, thus overcome metal with ceramic coating because the generation of the difference on thermal coefficient of expansion and elastic modelling quantity internal stress causes can occurring in the use problem of fine crack.In addition, because intensity, toughness and the wearability ratio aluminum oxide ceramic coating of the toughness reinforcing Al2O3 diphase ceramic material of ZrO2 are better, so the longer service life of ceramic overlapping curved pipe, the weight of ceramic overlapping curved pipe also is less than the cermet reticulated duct simultaneously.
