Opfindelsen angår et stanseapparat til udstansning af emner med kurvede eller buede kanter fra arkformet materiale, navnlig etiketter og lignende tryksagsemner i stort styktal i én arbejdsoperation, omfattende midler 5 til understøtning af en stabel med et stort antal arkfelter, der hver for sig indeholder ét af nævnte emner, og et over nævnte understøtningsmidler anbragt og i forhold dertil relativt bevægeligt stansejern, omfattende et hovedsageligt rørformet legeme, hvis ene ende er ud-10 formet som plan rundtgående skærekant svarende til formen af nævnte emner.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a punching apparatus for punching blanks with curved or curved edges from sheet-shaped material, in particular labels and similar large-scale printed matter in one operation, comprising means 5 for supporting a stack having a plurality of sheet fields each containing one of the said blanks, and a support means positioned above and relative thereto relatively movable, including a substantially tubular body, one end of which is formed as a plane circumferential cutting edge similar to the shape of said blanks.
Ved fremstilling af etiketter til brug på flasker og lignende frembringes et stort antal identiske etikettryk ved siden af hinanden på et arkformet materiale, som 15 f.eks. et papir- eller plastlaminat, og det trykte ark opskæres efter rette skærelinier i sædvanligvis rektangulære felter, som hver for sig rummer et etiketaftryk med en veldefineret beliggenhed indenfor det enkelte felt.In the manufacture of labels for use on bottles and the like, a large number of identical label prints are produced side by side on a sheet-shaped material such as e.g. a paper or plastic laminate, and the printed sheet is cut according to straight cutting lines in usually rectangular fields, each of which contains a label print with a well-defined location within the individual field.
Efter sammenstabling af et antal sådanne arkfelter 20 til en stabel eller et stød sker udstansning af etiketterne til deres endelige form ved hjælp af et stansejern af den ovennævnte art, idet et helt stød føres ind på en under stansejernet liggende, bevægelig trykplade, ved hvis efterfølgende aktivering stansejernet gennemskærer 25 arkfelterne i støddet, således at de udstansede etiket-emner ved trykpladens bevægelse presses gennem stansejernets indvendige hulhed.After stacking a plurality of such sheet fields 20 into a stack or punch, the labels are stamped to their final shape by means of a die of the aforementioned kind, an entire punch being inserted on a movable printing plate underneath the die, the subsequent activating the die cuts the 25 sheet fields in the punch so that the stamped label items are pushed through the inside of the die by the movement of the printing plate.
Ved kendte stansejern til dette formål har den indvendige hulhed for at nedsætte friktionen, når de udstan-30 Sede etiketemner presses gennem stansejernet, været udført med svagt skråtstillede vægge, således at hulhedens tværsnitsareal øges i retning bort fra stansejernets skærekant.In known punches for this purpose, the inner cavity for reducing friction when the embossed label items are pressed through the die has been made with slightly inclined walls such that the cross-sectional area of the cavity increases in direction away from the cutting edge of the die.
Som følge af, at det ved de kendte stansejern, der 35 sædvanligvis er fremstillet af værktøjsstål, er nødvendigt at foretage opslibning af skærekanten med forholdsvis korte intervaller, medfører den nævnte form, at tværsnitsarealet i skærekantens plan undergår en gradvis for- U9 m 2 øgelse, således at de udstansede etiketemner allerede efter forholdsvis få genopslibninger ikke længere holder de tilsigtede mål, til hvis nøjagtighed der af hensyn til den efterfølgende anvendelse i en etiketteringsmaskine 5 stilles forholdsvis strenge krav. Resultatet heraf er en kort levetid for stansejernet, således at dette ofte må kasseres efter et relativt beskedent antal genopslibninger .Due to the fact that in the known die-casting usually made of tool steel it is necessary to grind the cutting edge at relatively short intervals, the said shape causes the cross-sectional area of the cutting edge plane to undergo a gradual increase in the cutting edge. so that, after relatively few resurfaces, the stamped label items no longer meet the intended targets, for which the accuracy of the subsequent use in a labeling machine 5 sets relatively stringent requirements. The result of this is a short life of the die, so that this often has to be discarded after a relatively modest number of resins.
Til brug navnlig, men ikke udelukkende ved udstans-10 ning af etiketter og lignende tryksagsemner tilsigtes det ved opfindelsen at frembringe et stansejern, hvor de ovennævnte ulemper er afhjulpet.In particular, but not exclusively for stamping labels and similar printed matter, the invention aims to provide a die with the above-mentioned drawbacks being rectified.
Med henblik herpå er et stanseapparat ifølge opfindelsen ejendommeligt ved, at det rørformede legeme er frem-15 stillet af en sintret hårdmetallegering med en indvendig hulhed, hvor i det mindste det rørformede legemes inderside ved skærekanten er glatsleben og står vinkelret på skærekantens plan, medens tilslibning af skærekanten til foreskrevet skarphed og skærevinkel alene er foretaget på 20 ydersiden af det rørformede legeme.To this end, a punching apparatus according to the invention is characterized in that the tubular body is made of a sintered cemented carbide alloy with an internal cavity, at least the inside of the tubular body is smooth-cut and perpendicular to the plane of the cutting edge, while grinding of the cutting edge for the prescribed sharpness and cutting angle alone is made on the outside of the tubular body.
Med denne udformning af stanseapparatet kan der foretages et i praksis næsten ubegrænset antal genopslibninger med fuld bevarelse af skærekantens målnøjagtighed, og som følge af fremstillingen af en sintret hårdmetal-25 legering opnås yderligere en væsentlig forlængelse af tidsintervallerne mellem genopslibning i forhold til de kendte stansejern.With this design of the punching apparatus, a virtually unlimited number of resuspensions can be practiced, with full preservation of the cutting edge's target accuracy, and as a result of the manufacture of a sintered cemented carbide alloy, a further substantial extension of the time intervals between resuspending relative to the known punching iron is obtained.
Opfindelsen beror på erkendelsen af, at det ved stansejernets fremstilling er muligt at foretage slib-30 ning af de på skærekanten vinkelrette vægflader af den indvendige hulhed til en sådan glathed, at der opnås en ringe friktion, som tillader udformning af den indvendige hulhed med et konstant, til det udstansede emne svarende tværsnit på en betydelig længde regnet fra skære-35 kanten.The invention is based on the recognition that, in the manufacture of the die, it is possible to grind the wall surfaces perpendicular to the cutting edge perpendicular to the smoothness so as to obtain a slight friction which permits the forming of the inner cavity with a constant, corresponding to the punched blank corresponding to a considerable length from the cutting edge.
Med henblik på at lette udstansning fra en stabel eller et stød indeholdende et stort 3 149424 antal enkelte emner i én operation er en foretrukken udførelsesform for stanse apparatet ifølge opfindelsen ejendommelig ved, at den indvendige hulhed omfatter en ud til skaerekanten liggende del, hvor det rørformede legemes in-5 derside passer til formen af nævnte emner, og en hertil stødende del .med forøget tværsnitsareal,In order to facilitate punching from a stack or shock containing a large number of individual blanks in one operation, a preferred embodiment of the punching apparatus according to the invention is peculiar in that the inner cavity comprises a portion adjacent to the cutting edge where the tubular the inside of the body corresponds to the shape of said workpieces, and an adjacent portion thereof with increased cross-sectional area,
Udover til etiketter og lignende tryksagsemner kan et stansejern ifølge opfindelsen også finde anvendelse ved udstansning fra andre arkformede materialer, som 10 f.eks. tekstiler, gummi og lædervarer. Som eksempler på emner, der med fordel kan udstanses af sådanne materialer ved hjælp af et stanseapparat ifølge opfindelsen, kan nævnes overlæderemner og såler til brug ved skofremstilling, segmenter til tennisbolde og lignende emner med kurvet 15 eller buet, ikke-skarpkantet periferi.In addition to labels and similar printed matter, a die according to the invention may also be used for punching from other sheet-shaped materials such as e.g. textiles, rubber and leather goods. Examples of items which can be advantageously punched out by such materials by means of a punching apparatus according to the invention include upper leather and soles for use in shoe making, tennis balls segments and similar items with curved or curved, non-sharp-edged periphery.
Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, hvor fig. 1 skematisk illustrerer en udførelsesform for et stanseapparat ifølge opfindelsen, 20 fig. 2 viser et længdesnit af et stanseapparat ved udførelsesformen i fig. 1, og fig. 3 viser stansejernet i fig. 2, set i retning mod skærekanten.The invention will now be explained in more detail with reference to the drawing, in which 1 schematically illustrates an embodiment of a punching apparatus according to the invention; FIG. 2 shows a longitudinal section of a punching apparatus in the embodiment of FIG. 1, and FIG. 3 shows the punch in FIG. 2, towards the cutting edge.
Ved et etiketstanseapparat som illustreret i fig. 1 25 er udgangsmaterialet en stabel eller et stød 1, indeholdende et stort antal sædvanligvis rektangulære arkfelter med hvert sit individuelle etiketaftryk. Sådanne arkfelter, som ikke er vist på tegningen, er ved en forudgående operation frembragt ud fra et trykark indeholdende 30 et stort antal side om side liggende etiketaftryk ved opskæring af dette ark efter rette skærelinier.In a label punching apparatus as illustrated in FIG. 1 25, the starting material is a stack or punch 1 containing a large number of usually rectangular sheet fields, each with its own individual label print. Such sheet fields, not shown in the drawing, are produced by a preliminary operation from a printing sheet containing a large number of side-by-side label prints by cutting this sheet along straight cutting lines.
Støddet 1, i hvilket de enkelte arkfelter som nævnt bærer hvert sit etiketaftryk med en veldefineret beliggenhed i forhold til arkfeltets tilskårne kanter, 35 føres ved hjælp af et styr 2 ind på en understøtningsplade i form af en f.eks. hydraulisk eller pneumatisk drevet trykplade 3, som befinder sig under stanse- 4 U9424 jernet 4 parallelt med planet indeholdende stansejernets skærekant.The shock 1, in which the individual sheet fields, as mentioned above, each carry their own label print in a well-defined position with respect to the cut edges of the sheet field, is introduced by means of a guide 2 into a support plate in the form of a e.g. hydraulic or pneumatically driven pressure plate 3, which is under the die 4 U9424 iron 4 parallel to the plane containing the cutting edge of the die.
Ved aktivering af trykpladen 3 til bevægelse i retning mod stansejernet 4 udskæres de individuelle 5 etiketemner på arkfelterne i støddet 1, og de udstansede etiketemner presses' gennem stansejernets indvendige hulhed.By activating the printing plate 3 for movement in the direction of the die 4, the individual 5 label pieces are cut on the sheet fields in the punch 1 and the stamped label pieces are pressed through the inner cavity of the die.
Med henblik på fjernelse af den tilbageblivende, bortskårne del af arkfelterne i støddet 1 er der i til-10 slutning til stansejernet 4's skærekant på i og for sig kendt måde anbragt en opskæringskniv 5.In order to remove the remaining, cut-off part of the sheet fields in the support 1, a cutting knife 5 is arranged in connection with the cutting edge 4 of the cutting edge 4 in a manner known per se.
Som det nærmere fremgår af fig. 2 og 3, omfatter det i sin helhed med 4 betegnede stansejern ifølge opfindelsen et hovedsageligt rørformet legeme 6, hvis ene 15 ende er udformet som en plan rundtgående skærekant 7 svarende til formen af.de etiketemner, der skal udstanses. Det rørformede legeme 6 er fremstillet af en sintret hårdmetallegering, hvortil der foretrækkes en wol-fram-koboltlegering, fortrinsvis en 20 legering, som indeholder i det væsentlige 90% wolfram-karbid og 10% kobolt.As will be more apparent from FIG. 2 and 3, the full stamped iron of the present invention, designated as 4, comprises a substantially tubular body 6, one end of which is formed as a plane circumferential cutting edge 7 corresponding to the shape of the label items to be punched. The tubular body 6 is made of a sintered cemented carbide alloy to which a wool-framed cobalt alloy is preferred, preferably an alloy containing substantially 90% tungsten carbide and 10% cobalt.
I overensstemmelse med opfindelsen er det rørformede legeme 6 fremstillet med en indvendig hulhed, hvis vægside 8 er glatsleben og i det mindste ved skærekanten 25 7 er vinkelret på skærekantens plan, medens den fornødne skarphed af skærekanten 7 alene er tilvejebragt ved tilslibning på ydersiden af det rørformede legeme 6.In accordance with the invention, the tubular body 6 is made with an internal cavity whose wall side 8 is smooth-cut and at least at the cutting edge 25 7 is perpendicular to the plane of the cutting edge, while the necessary sharpness of the cutting edge 7 is provided only by grinding on the outside of it. tubular body 6.
Tilslibningen af skærekanten 7 kan f.eks. foretages ved hjælp af en slibemaskine, der som vist i fig. 2 30 ved 9a og 9b frembringer en rundtgående slibning i en art facetter, hvoraf i det mindste slibningen 9a nærmest skærekanten 7 er en hulslibning til opnåelse af en foreskrevet skærevinkel ved skærekanten 7.The sanding of the cutting edge 7 can e.g. is carried out by means of a grinding machine which, as shown in FIG. 2 at 9a and 9b produce a circumferential grinding in a kind of facets, at least the grinding 9a closest to the cutting edge 7 being a hollow grinding to obtain a prescribed cutting angle at the cutting edge 7.
Til brug ved udstansning af etiketter og lignende 35 tryksagsemner er skærevinklen fortrinsvis mellem 5° og 10°, f.eks. ,ca. 7°.For use in stamping labels and similar printed matter, the cutting angle is preferably between 5 ° and 10 °, e.g. , C. 7 °.
