Abstract
The present invention relates to a kind of cutter (2,3) for cutter sweep in producing the machine of product of the tobacco industry, wherein, cutter (2,3) are made up of martensitic stain less steel.
Description
The present invention relates to the cutter for cutter sweep in producing the machine of rod-shaped objects of the tobacco industry of a kind of preamble special-shaped with claim 1.
The rod-shaped objects of the tobacco industry e.g. medicated cigarette, cigarlet or filter plug.Content material shape is packed regularly wherein by these products with packaging material, such as paper.Using modern machines to produce rod-shaped objects, this machine, including such job step, i.e. cuts rod-shaped objects by cutter in this job step in cutter sweep from the tobacco rods of conveying continuously.
Cutter sweep includes the knife rest rotated, and cutter are fixed on described knife rest, and include the pipe with the guider for guiding tobacco rods.Described guider also forms the bearing of the cutter crossing tobacco rods except guiding outer to tobacco rods while.Owing to this abrasion of fair wear and tear to be experienced of cutting frequency height cutter causes the cut edge of the cutting surfaces of tobacco rods uneven.In order to this abrasion is compensated, by one or more sharpening dish, cutter are sharpened in the machine, and by feed arrangement by its supplementary propelling towards direction, cut edge.Cutting must be switched off after certain abrasion, generally have to interrupt the operation of machine for this.
This shortcoming sharpened again of cutter is to there will be spark during sharpening.These sparks are to be reduced to minimum in principle, because owing to spark splashes the parts of machine in extreme circumstances itself, or tobacco rods can be impaired, or even can be burned.
The task of the present invention is to provide a kind of cutter.This cutter can reduce the formation of spark when sharpening, and has high wearability.
In order to complete this task according to it is proposed that, cutter are formed by stainless martensite steel.Martensite steel has the advantage that, the martensite i.e. occurred in hardening process by austenite conversion causes significantly improving wearability.Martensite can be formed when the steel with the carbon content more than 0.2% being cooled down suddenly in hardening process.Additionally, steel should be stainless, this can be reached by following measure, and its way is, this steel has the chromium of at least 10.5%, and the carbon of most 1.2%.Chromium component causes forming the most wear-resisting carbide in steel when hardening.The wearability of cutter can be improved the most further by this carbide.The wearability of cutter is mainly by carbide rather than is that the tension by grizzly bar row (Gitterverband) obtains as in the case of the cutter of prior art in this case.Another advantage used as the composition of alloy by chromium is to be improve by incombustible chromium and cause spark to form required energy, as a result of which it is, totally say the formation of spark when can reduce sharpening when the sharpening speed of regulation.Therefore, use rustless martensite steel to provide by suggestion cutter and there is high service life, or wearability, and produce the cutter of less spark when sharpening simultaneously.Thus can provide such cutter, the most this cutter simply means can have the characteristic of improvement in terms of two standards.Additionally, sharpening speed also can be brought up to 60 meter per seconds, and at the spark produced among these not over the degree jeopardizing equipment safety always.It is produced from and another advantage is that, during transportation, or also need not give cutter oiling at memory period in order to avoid corrosion.
Showing through different tests, steel should have the chromium (Cr) of at least 10.5%, so, almost can completely stop when sharpening speed and being 30-60 meter per second and spark occurs.
In addition test is it is also shown that steel should have 0.2-1.2%, and preferably 0.8% at carbon component, and sample just can be by the hardness of hardening of steel to required at least 500HV.
In addition test has 0.2-1.0% it is also shown that work as steel, and niobium (Nb) composition of preferably 0.7% is favourable.Niobium is also a kind of carbide former, and the advantage of this carbide former is to quickly form Niobium carbide, can be stoped forming the biggest chromium carbide by the formation of this Niobium carbide.Due to carbide totally the least thus can the blade of cutter be sharpened thinner, the sharpest.This is again favourable to the quality of the facet of product.
Additionally, the present invention also advises, steel has 0.5-1.5%, molybdenum (Mo) composition of preferably 1.1%.Alloy carbide is formed again by this molybdenum.The ruggedness of cutter, or wearability is can further improve by this special carbonization.
Another preferred form of implementation of the present invention is that steel has 0.5-1.5%, the composition of the vanadium (V) of preferably 0.9%.The intercrystalline corrosion being likely to occur due to the formation of carbide is reduced by vanadium.Additionally, by vanadium, when the hardness of cutter can be stoped to be decreased until cutter be heated to temperature 600 degree, the heating caused by sharpening can be stoped to reduce again the hardness of cutter by this measure.This prevention hardness declines the service life causing again extending cutter.
Additionally, in order to obtain enough wearabilities, the present invention also advises, cutter have the hardness of at least 400-700HV, it is therefore preferred to have the hardness of 600HV.
By a preferred embodiment, the present invention is described in more details below.This unique figure is:
Fig. 1: be used for producing tobacco products, and there is the knives rack of the cutter sweep of the machine of the cutter according to the present invention.
In FIG it can be seen that be used for producing tobacco products, and there is the cutter sweep of rotatable knives rack 1, described knives rack accompanies two cutter 2 and 3.The product of the tobacco industry can be such as medicated cigarette, cigarlet, or filter plug.These products are cut according to the length of regulation from the volume bar carried by cutter sweep.To this end, cutter sweep has two cutter 2 and 3.It is suspended on toolframe 1 described cutter universal joint, and carries out the relative rotary motion relative to toolframe 1 by unshowned machinery during knife rest 1 rotary motion.Additionally, also set up the Sharpening device 4 with the sharpening dish 5 by motor-driven on cutter sweep.Cutter 2 and 3 pass through to sharpen from described sharpening dish with regular spacing.Wherein, the sharpening speed of the cutter 2 and 3 30-60 meter per second to be produced by the velocity of rotation of toolframe 1 and sharpening dish 5 is sharpened.
In order to reduce the spark occurred when sharpening, it is made up of martensitic stain less steel according to cutter 2 and 3 of the present invention.Exemplary steel class is such as open with material number 1.4153.03.
Steel is martensite, say, that it has the carbon component of 0.8%, and the most hardenable to more than 400HV, preferably arrives the hardness of 600HV.Enough ruggedness, or wearability is can reach by thus acquired hardness, so, optional the greatlyyest in the quantity changing the product cut between interval with cutter 2 and 3.Can be reached by following measure to obtain the enough martensite compositions in steel of required hardness, i.e. the composition of carbon is between 0.2-1.2%, and wherein, the Confirmation Of Number of 0.8% is particularly advantageous.Additionally, the steel for cutter 2 and 3 selection is a kind of rustless steel, this this means that according to the regulation of standard DINEN10020, and steel has the chromium component of at least 10.5%.This chromium component causes reducing the spark occurred when sharpening, because by incombustible chromium, improves for forming the energy required by spark by the microgranule of release during sharpening.
Additionally, cause formation carbide to cause improving further hardness by chromium, the use time of cutter 2 and 3 so can be improved further.
Therefore, using the not only available required wearability of the rustless steel of martensite by cutter 2 and 3, and can reduce and spark occur, therefore, the steel proposed by employing simply means can improve the characteristic of cutter 2 and 3 in terms of two standards.
Additionally, the steel of cutter 2 and 3 has 0.2-1.0%, the niobium composition of preferably 0.7%, so, make the chromium carbide of formation diminish by quickly being formed of Niobium carbide.Can sharpen cutter 2 and cutter more subtly by less chromium carbide, the blade of cutter 2 and 3 is sharper in such event, and improves the quality of the facet of product.
Additionally, by 0.5%-1.5%, the alloy of the molybdenum of preferably 1.1% adds the formation that can improve carbide further.Molybdenum is also that a kind of so-called alloy carbide produces element, preferably forms the most undersized by this element, and has the carbide of above-mentioned advantage.
Additionally, the material of cutter can have 0.5-1.5%, the vanadium composition of preferably 0.9%, can prevent cutter 2 and 3 from being declined by thermally-induced hardness by this vanadium composition.Because alloying component vanadium is also carbide produces element, so also can obtain such as the advantage similar by interpolation niobium or molybdenum by adding vanadium.
The hardness of cutter 2 and 3 is at least 400-700HV, it is therefore preferable to 600HV.Described hardness can be adjusted by corresponding martensite composition and the carbide comprised wherein.
Alternatively or additionally can be by the appearance of Effects of Heat Treatment carbide targetedly.
