Abstract
The invention relates to a blade (2, 3) for a cutting device in a machine for producing products in the tobacco processing industry. Said blade (2, 3) is made from a rust-resistant martensitic steel.
Description
The present invention relates to a kind of cutter that are used for cutter sweep in the machine of the rod-shaped objects of producing the tobacco industry with preamble special-shaped of claim 1.
The rod-shaped objects of the tobacco industry for example is cigarette, cigarlet or filter tip.In these products, use packaging material, for example paper with content material fixed in shape ground packing wherein.Adopt modern machines in order to produce rod-shaped objects, this machine promptly cuts rod-shaped objects by cutter comprising such job step from the tobacco rods of continuous conveying in cutter sweep in this job step.
Cutter sweep comprises the knife rest of rotation, and cutter are fixed on the said knife rest, and comprises the pipe with the guider that is used to guide tobacco rods.Said guider is also formed the bearing of the cutter that cross tobacco rods simultaneously except tobacco rods is led.Because will experiencing this wearing and tearing of fair wear and tear, the high cutter of cutting frequency cause the cut edge on cutting surface of tobacco rods uneven.For this wearing and tearing are compensated, in machine, cutter are carried out sharpening, and pass through feed arrangement its additional propelling of direction towards the cut edge by one or more sharpening dish.After certain wearing and tearing, must cuts be changed, must interrupt the operation of machine usually for this reason.
The shortcoming of this sharpening again of cutter is during sharpening, spark can occur.These sparks say in principle be reduced to minimum because because spark splashes in the parts of machine under the extreme case itself, perhaps tobacco rods understand impaired, perhaps even can be burnt.
Task of the present invention provides a kind of cutter.This cutter can reduce the formation of spark when sharpening, and have high wearability.
Advise according to the present invention that in order to accomplish this task cutter are formed by stainless martensite steel.Martensite steel has such advantage, and the martensite that promptly occurs in hardening process through the austenite conversion causes improving widely wearability.When in hardening process, forming martensite when steel greater than 0.2% carbon content cools off suddenly to having.In addition, steel should be stainless, and this can reach through following measure, and its way is, this steel has at least 10.5% chromium and maximum 1.2% carbon.Chromium component causes when sclerosis, in steel, forming very wear-resisting carbide.Can totally further improve the wearability of cutter through this carbide.The wearability of cutter mainly is through carbide in this case, rather than is that tension through grizzly bar row (Gitterverband) obtains as in the situation of the cutter of prior art.With chromium be, improved through incombustible chromium and caused that spark forms required energy, consequently, totally say the formation of the spark in the time of when the sharpening speed of regulation, can reducing sharpening as another advantage that the composition of alloy uses.Therefore, use rustless martensite steel to provide to have high service life through the suggestion cutter, perhaps wearability, and when sharpening, produce the cutter of less spark simultaneously.So just such cutter can be provided, promptly this cutter simply means have improved characteristic aspect two standards.In addition, also can sharpening speed be brought up to 60 meter per seconds always, and can not surpass the degree that jeopardizes device security at this spark that wherein produces.Generation is during transportation, perhaps also needn't give the cutter oiling at memory period for fear of corrosion from another advantage of the present invention.
Show that through different tests steel should have at least 10.5% chromium (Cr), like this, when sharpening speed is the 30-60 meter per second, almost can stop fully and spark occur.
Test shows that also steel should have 0.2-1.2% in addition, and preferably 0.8% at carbon component, and appearance just can be with the hardness of hardening of steel to desired at least 500 HV.
Test also shows in addition, and when steel has 0.2-1.0%, preferably 0.7% niobium (Nb) composition is favourable.Niobium also is a kind of carbide former, and the advantage of this carbide former is to form the niobium carbide soon, and the formation through this niobium carbide can stop the very big chromium carbide of formation.So can the blade sharpening of cutter be got thinner, more sharp owing to carbide is overall less.This quality to the cut surface of product is again favourable.
In addition, the present invention advises that also steel has 0.5-1.5%, preferably 1.1% molybdenum (Mo) composition.Form alloy carbide again through this molybdenum.Can further improve the durability of cutter, perhaps wearability through this special carbonization.
Another preferred form of implementation of the present invention is that steel has 0.5-1.5%, preferably the composition of 0.9% vanadium (V).Reduce because the intercrystalline corrosion that the formation of carbide possibly occur through vanadium.In addition, through vanadium, the decrease of hardness that can stop cutter can stop because the caused heating of sharpening reduces the hardness of cutter again through this measure up to cutter being heated to temperature 600 when spending.This prevention decrease of hardness causes prolonging the service life of cutter again.
In addition, in order to obtain enough wearabilities, the present invention advises that also cutter have the hardness of 400-700 HV at least, preferably have the hardness of 600 HV.
By a preferred embodiment the present invention is described in more details below.This unique figure is:
Fig. 1: be used to produce tobacco products, and have knives rack according to the cutter sweep of the machine of cutter of the present invention.
In Fig. 1, can see being used to produce tobacco products, and have the cutter sweep of rotatable knives rack 1, on said knives rack, accompany two cutter 2 and 3.The product of the tobacco industry for example can be cigarette, cigarlet, perhaps filter tip.These products are cut from the volume bar length according to the rules that is transferred by cutter sweep.For this reason, cutter sweep has two cutter 2 and 3.Be suspended on the toolframe 1 said cutter universal joint, and during knife rest 1 rotatablely moves, carry out relative rotary motion with respect to toolframe 1 through unshowned machinery.In addition, on cutter sweep, also be provided with and have Sharpening device 4 through electric motor driven sharpening dish 5. Cutter 2 and 3 with spacing clocklike from said sharpening dish through to carry out sharpening.Wherein, the sharpening speed of the 30-60 meter per second that produces with the velocity of rotation through toolframe 1 and sharpening dish 5 of cutter 2 and 3 is by sharpening.
For the spark that reduces to occur when the sharpening, cutter 2 and 3 are processed by martensitic stain less steel according to the present invention.Exemplary steel class is for example open with material number 1.4153.03.
Steel is martensitic, that is to say that it has 0.8% carbon component, and therefore can harden to greater than 400 HV, preferably to the hardness of 600 HV.Hardness through being obtained thus can reach enough durabilities, and perhaps wearability like this, can be selected greatly accordingly in the quantity of changing the product that cuts with cutter 2 and 3 between intermittence.For the enough martensite compositions in steel of obtaining desired hardness can reach through following measure, promptly the composition of carbon is between 0.2-1.2%, and wherein, 0.8% Confirmation Of Number is particularly advantageous.In addition, the steel of selecting for cutter 2 and 3 is a kind of stainless steel, and this stipulates that according to standard DIN EN's 10 020 this is meaning, and steel has at least 10.5% chromium component.This chromium component causes reducing the spark that when sharpening, occurs, because through incombustible chromium, has improved the particulate that is used for through discharging in the sharpening process and has formed the desired energy of spark.
In addition, cause that through chromium forming carbide causes improving further hardness, can improve the service time of cutter 2 and 3 so further.
Therefore, use martensitic stainless steel not only can obtain desired wearability, and can reduce and spark occurs through cutter 2 and 3, therefore, adopt the steel of being advised simply means aspect two standards, improve the characteristic of cutter 2 and 3.
In addition, cutter 2 and 3 steel have 0.2-1.0%, 0.7% niobium composition preferably, and like this, the quick formation through the niobium carbide has diminished the chromium carbide of formation.Through littler chromium carbide sharpening cutter 2 and cutter more subtly, cutter 2 and 3 blade are sharper in such event, and have improved the quality of the cut surface of product.
In addition, through 0.5%-1.5%, preferably the alloy of 1.1% molybdenum adds the formation that can improve carbide further.Molybdenum also is that a kind of so-called alloy carbide produces element, preferably form through this element more undersized, and carbide with above-mentioned advantage.
In addition, the material of cutter can have 0.5-1.5%, and 0.9% vanadium composition preferably can prevent the decrease of hardness that cutter 2 and 3 are caused by heat through this vanadium composition.Because also being carbide, the alloying component vanadium produces element, so also can obtain as passing through to add niobium or the similar advantage of molybdenum through adding vanadium.
Instead or additionally can pass through the appearance that heat treatment targetedly influences carbide.
