Description

i DK 166662 B1in DK 166662 B1

Opfindelsen angår et båndstålstanseværktøj af den i krav l's indledning angivne art. Fra DE-patentskrift nr. 31 33 980 kendes et båndstålstanseværktøj, med hvilket der fra et papir- eller kartonark i flere stanse-5 trin samtidigt kan udstanses flere emner ved, at der parallelt med båndstålstanseknivene og tæt ved siden af disse er fastklæbet profilstrimler af skumgummi, ved hjælp af hvilke de enkelte emner under stansningen atter løftes op over båndstålstanseknivenes skæreægge 10 til videretransport af hele papir- eller kartonarket.The invention relates to a strip steel punching tool of the kind specified in the preamble of claim 1. DE Patent Specification No. 31 33 980 discloses a strip steel punching tool, with which a plurality of punches can be simultaneously punched from a paper or cardboard sheet at several stages by the parallel strips of the strip steel punching knives and adjacent to them foam rubber, by means of which the individual items during the punching are raised again over the cutting edges 10 of the strip steel cutter knives for further transport of the entire paper or cardboard sheet.

For at de stansede dele ikke skal falde ud, er disse endnu forbundet med hinanden punktvis, idet der i båndstålstanseværktø jerne findes udsparinger, så at de enkelte emner på disse steder endnu er forbundet indbyr-15 des ved materialerester. Såfremt emnerne ikke på kor rekt vis løftes ud af stansekniv formene, kan papirarkene som helhed ikke længere videretransporteres til den næste stansestation, hvorved den kontinuerlige produktion standses.In order that the punched parts should not fall out, they are still connected to each other in point form, with recesses in the band steel punching tools, so that the individual blanks in these places are still interconnected by material residues. If the blanks are not properly lifted out of the die cutting molds, the sheets of paper as a whole can no longer be transported to the next punching station, thereby stopping continuous production.

20 Det er endvidere kendt at anbringe fjederpåvirkede ud- kastere mellem båndstålstanseknivene, hvilket imidlertid er kompliceret og bekosteligt.Furthermore, it is known to place spring-loaded ejectors between the band steel punch blades, which, however, is complicated and costly.

De kendte profilstrimler har med henblik på en enkel fremstilling og anbringelse et kvadratisk tværsnit.The known profile strips have a square cross section for easy manufacture and placement.

25 Især når der ved stansning på modpladen er anbragt præ ge- eller rillematricer, deformeres de enkelte emner, og papiret eller kartonen rives itu, inden materialet er helt gennemstanset. Især når kartonen er forsynet med et dæklag, er dette tilbøjeligt til at flosse ud, 30 så at der fås meget uskønne flossede stansekanter, især når overfladen er farvet. Forbindelsesstederne skal til forhindring af deres overrivning have forholdsvis store tværsnitsdimensioner.25 In particular, when stamping or grooving matrices are placed on the counterplate, the individual blanks are deformed and the paper or cardboard torn apart before the material is completely punched. Especially when the carton is provided with a cover layer, this tends to floss, so that very unkempt frayed punch edges are obtained, especially when the surface is colored. The joints must have relatively large cross-sectional dimensions to prevent their tearing.

DK 166662 B1 2DK 166662 B1 2

Opfindelsen tager sigte på at afhjælpe ovennævnte ulemper ved forbedring af et båndstålstanseværktøj af den angivne art på en sådan måde, at der opnås en stansning med rene kanter uden frynser, selv når der anvendes 5 prægematricer. Desuden skal forbindelsstederne kunne have et så lille materialetværsnit som muligt, så at emnerne senere let kan skilles ad. Ovennævnte formål opnås ved det i krav l's kendetegnende del angivne.The invention aims to alleviate the aforementioned disadvantages of improving a strip steel punching tool of the kind specified in such a way as to obtain a punch with clean edges without fringes, even when 5 embossing matrices are used. In addition, the connection points must be able to have as small a material cross section as possible, so that the items can be easily separated later. The above object is achieved by the characterizing part of claim 1.

Ved denne bevægelsestendens spændes emnernes stansede 10 kanter mod hinanden, så at risikoen for en for tidlig udrivning inden den fuldstændige gennemstansning er væsentlig reduceret, og der derved fås en bedre kantkvalitet. Desuden nedsættes trækbelastningen på forbindelsesstederne væsentlig, så at disses nødvendige tvær-15 snitsflader kan holdes små, og der senere efter fuld stændig adskillelse blot resterer kun lidt generende små afrivningsflader. Ved vertikal belastning forsættes stansematerialekontaktfladen i sideretningen. Hældningsvinklen over for lodret kan hensigtsmæssigt være 20 ca. 10°.At this movement tendency, the punched edges of the blanks are tensioned against each other, so that the risk of premature tearing before complete punching is substantially reduced, thereby providing a better edge quality. In addition, the tensile load at the junction sites is substantially reduced so that their required cross-sectional surfaces can be kept small, and only after a complete separation, only slightly annoying small tear surfaces remain. For vertical loading, the punch material contact surface is moved in the lateral direction. The angle of inclination to the vertical may conveniently be 20 approx. 10 °.

Samme virkning kan opnås ved det i krav 3 angivne, og denne virkning kan yderligere forstærkes ved det i krav 4 angivne. I tilfælde af en hældningsvinkel danner dette tværsnitsområde en vinkel med basisfladen, og det 25 tipper ved vertikal belastning under stanseprocessen, hvorved hældningsvinklen øges.The same effect can be obtained from that of claim 3, and this effect can be further enhanced by that of claim 4. In the case of an angle of inclination, this cross-sectional area forms an angle with the base surface and it tips at vertical load during the punching process, thereby increasing the angle of inclination.

Den omtalte tippebevægelse under stanseprocessen kan ifølge opfindelsen også opnås ved, at profilstrimlen er udformet som hulprofil, hvis vinkelret på bærepladen 30 forløbende indre vægge skråner i retning mod båndstål- stanseknivens skær, idet ifølge opfindelsen profilstrimlen kan have et tilnærmet parallellogramformet tværsnit, og der ved belastning fås en parallelforskydning af stansematerialekontaktfladen i forhold til skæreæg- DK 166662 B1 gen i lighed med en parallellogramagtig ledfirkants sammenklapningsbevægelse.According to the invention, the said tipping movement during the punching process can also be achieved by the profile strip being formed as a hollow profile if the inner walls extending perpendicular to the support plate 30 are inclined towards the cutter of the strip steel die cutter, according to the invention the profile strip may have an approximate parallelogram shape. load, a parallel displacement of the punch material contact surface relative to the cutting edge is obtained, similar to the folding motion of a parallelogram-like joint square.

Ifølge opfindelsen kan profilstrimlens bort fra bånd-stålstansekniven vendende kant være stærkt afrundet, 5 så at der opnås en jævn overgang for fladepresningen og dermed vidtgående undgås pressesteder i kantområdet, eller sådanne pressesteder i det mindste bliver langt mindre synlige.According to the invention, the edge of the profile strip away from the strip-steel punch knife can be strongly rounded so that a smooth transition for the surface pressing is achieved and thus far avoiding pressing points in the edge region, or such pressing points at least become much less visible.

Profilstrimlen kan være sammensat af mindst to delstrimler 10 af skumgummi, af hvilke den nærmest båndstålstansekniven værende delstrimmel har størst hårdhed.The profile strip may be composed of at least two foam rubber sub-strips 10, of which the closest strip steel strip knife has the greatest hardness.

Til øgning af de anvendte hulprofilers langtidsstyrke kan ifølge opfindelsen overgangene i hulprofilens indre være afrundet.In order to increase the long-term strength of the hollow profiles used, according to the invention, the transitions in the interior of the hollow profile may be rounded.

15 I det følgende forklares opfindelsen nærmere ved hjælp af tegningen, hvor fig. 1 er et partielt snit i en udførelsesform for stanseværktøjet ifølge opfindelsen, og fig. 2 til 5 viser forskellige udførelsesformer for 20 profilstrimler.15 In the following, the invention is explained in more detail with reference to the drawing, in which fig. 1 is a partial sectional view of one embodiment of the punching tool according to the invention; and FIG. Figures 2 to 5 show different embodiments of 20 profile strips.

Ved den efterfølgende beskrivelse af forskellige udførelseseksempler for værktøjet ifølge opfindelsen er analoge dele betegnet med samme henvisningsbetegnelser.In the following description of various exemplary embodiments of the tool according to the invention, analogous parts are designated by the same reference numerals.

Den i fig. 1 i tværsnit viste del af båndstålstanse-25 værktøjet ifølge opfindelsen har en bæreplade 1 af kryds finer med slidser 2, i hvilke der er indsat stanseknive 3 af båndstål. Knivene 3 er med deres ryg 4 understøttet af en hærdet stålplade 5, så at knivenes modstående skær 6 ikke kan undvige under belastning. På begge sider i 4 DK 166662 Bl af knivene 3 er anbragt profilstrimler 7, 7r med en kontatkflade 9 for det materiale, der skal stanses, hvilken er beliggende parallelt med bærepladen l's overflade 8, og hvormed profilstrimlerne rager op over kniv-3 skærene 6. Profilstrimlerne 7, 7' er så tæt som muligt ved knivene 3 fastgjort, fortrinsvis fastklæbet på bærepladen l's øvre flade 8.The FIG. 1 is a cross-sectional view of the strip steel punch tool according to the invention having a plywood veneer 1 with slots 2 into which strip steel punching knives 3 are inserted. The knives 3 are supported with their backs 4 by a hardened steel plate 5, so that the opposite cutting edge 6 of the blades cannot avoid under load. On both sides of the knives 3, profile strips 7, 7r are provided with a contact surface 9 for the material to be punched, which is parallel to the surface 8 of the support plate 1 and with which the profile strips protrude over the knife-3 inserts 6. The profile strips 7, 7 'are secured as closely as possible to the blades 3, preferably adhered to the upper surface 8 of the support plate 1.

Under stanseprocessen anbringes papir- eller kartonarket, der skal bearbejdes, på profilstrimlernes kontakt-10 flade 9, hvorefter en ikke vist modplade på kendt vis presses mod knivskærene 6, hvorved profilstrimlerne 7, 7' sammentrykkes, indtil kartonen eller papiret er gennemstanset. Dernæst løftes modpladen atter op. På grund af profilstrimlernes elasticitet løftes de gen-15 nemstansede emner, der endnu er forbundet med hinanden på ikke viste forbindelsessteder, op fra knivskærene 6. Det samlede papir- eller kartonark kan dernæst fremføres til den næste bearbejdsningsstation uden risiko for, at det bliver hængende i båndstålstanseknivene 20 3.During the punching process, the paper or cardboard sheet to be machined is placed on the contact surface 9 of the profile strips, after which a counterplate not shown in the known manner is pressed against the cutters 6, thereby compressing the profile strips 7, 7 'until the cardboard or paper is punched. Next, the counterplate is raised again. Due to the elasticity of the profile strips, the punched items still connected to each other at lifting points not shown are lifted from the cutters 6. The assembled paper or cardboard sheet can then be fed to the next processing station without the risk of being stuck in the strip steel punching knives 20 3.

Til undgåelse af en for tidlig overrivning på stansestedet under indvirkning af trækkræfter i kartonen, har profilstrimlerne 7, 7' en speciel form. Fig. 2 til 4 viser forskellige udførelsesformer for profilstrim-25 lerne. Fig. 2 viser en massiv profilstrimmel af skum gummi eller korkgummi. Profilstrimlens mod den ikke viste båndstansekniv 3 vendende sideflade 10 danner med lodret en vinkel 11, som kan variere alt efter anvendelsesformålet. En vinkel 11 på ca. 10 til 15° har 30 vist sig at være særlig fordelagtig ved bearbejdning af sædvanlig karton til foldeæsker. Ved hjælp af en runding 12 eller skråflade ved profilstrimiens bort fra stansekniven 3 vendende øvre kant mindskes fremkomsten af synlige aftryk på kartonen, især i tilfælde af DK 166662 Bl 5 følsomme overflader.To avoid premature tearing at the punching site under the influence of tensile forces in the carton, the profile strips 7, 7 'have a special shape. FIG. Figures 2 to 4 show different embodiments of the profile strips. FIG. 2 shows a solid profile strip of foam rubber or cork rubber. The side surface 10 of the profile strip facing the band punch knife 3 not shown is vertically formed at an angle 11 which may vary according to the purpose of use. An angle 11 of approx. 10 to 15 ° 30 has been found to be particularly advantageous in machining conventional cardboard for folding boxes. By means of a rounding 12 or oblique surface at the upper edge facing away from the punching knife 3, the appearance of visible imprints on the carton is reduced, especially in the case of sensitive surfaces.

Fig. 3 viser en hulprofil-profilstrimmel med et tilnærmet trapezformet tværsnit. Det indre hulrum 14 i profilstrimlen har afrundede hjørner 13 til opnåelse 5 af en øget styrke i lang tid. Til øgning af forskyd ningsvirkningen i retning mod kniven 3 har det nærmest kniven 3 beliggende nedre hjørne 13' og det længst borte fra kniven beliggende øvre hjørne 13" i profilstrimlens hulrum 14 en større krumningsradius end de øvrige 10 to hjørner 13.FIG. 3 shows a hollow section profile strip with an approximately trapezoidal cross section. The inner cavity 14 of the profile strip has rounded corners 13 to obtain 5 of increased strength for a long time. To increase the shear action in the direction of the knife 3, the lower corner 13 'located closest to the knife 3 and the furthest corner 13 "furthest away from the knife, in the profile strip cavity 14 has a greater radius of curvature than the other two corners 13.

Til yderligere øgning af forskydeligheden mod knivskæret kan profilstrimlen 7 have tværsnitspartier 15, 15' bestående af gummi, skumgummi eller lignende med forskellig hårdhed, idet det parallelt med sidefladen 10 15 forløbende og denne dannende tværsnitsparti 15 har størst hårdhed (over 40 Shore). Overgangen mellem dette hårde tværsnitsparti 15 og profilstrimlens resterende tværsnit 15' er i fig. 3 og 4 antydet ved en kortstreg-linie 16. Profilstrimlernes nævnte tværsnitspartier med for-20 skellig hårdhed kan f.eks. være sammenklæbet.To further increase the cutting blade displacement, the profile strip 7 may have cross-sectional portions 15, 15 'consisting of rubber, foam rubber, or the like with different hardness, with the greatest hardness (over 40 Shore) running parallel to the side surface 10 15. The transition between this hard cross-sectional portion 15 and the remaining cross-section 15 'of the profile strip is shown in FIG. 3 and 4 are indicated by a dashed line 16. The said cross-sectional sections of the profile strips of different hardness may e.g. be glued.

Til yderligere øgning af profilstrimlernes evne til at tippe i retning mod stanseknivene kan som vist i fig. 4 profilstrimlernes modsat disses nærmest stansekniven 3 værende sideflade 10 beliggende sideflade 17 25 forløbe parallelt med førstnævnte sideflade 10, som vist ved kortstreg-linierne til højre i fig. 4.To further increase the ability of the profile strips to tip in the direction of the punch blades, as shown in FIG. 4, opposite side 17 of the profile strips opposite to the punching knife 3, the lateral surface 17 of the profile strip 10 is parallel to the first mentioned side surface 10, as shown by the dashed lines to the right in FIG. 4th

Ved en i fig. 5 vist yderligere udførelsesform for en elastisk profilstrimmel findes der i sidefladen 10, der vender mod stansekniven og danner en vinkel på ca.In one of FIG. 5 shows another embodiment of an elastic profile strip is found in the side surface 10 facing the punching knife and forming an angle of approx.
