Abstract
Description
Die Erfindung betrifft die Verwendung eines vorvergüteten Werkzeugstahls für die Herstellung von Formen für Kunststoffteile, insbesondere für Matrizen mit großen Abmessungen.The invention relates to the use of a pre-tempered tool steel for the Production of molds for plastic parts, in particular for matrices with large ones Dimensions.
Kunststofformen zum Spritzen oder Pressen von Kunststoffteilen bestehen stets aus zwei Hälften, einer Matrize und dem Kernteil. Die Oberflächengüte des Kunststoffteils wird durch die Qualität des Matrizenwerkstoffes wesentlich bestimmt.Plastic molds for spraying or pressing plastic parts always exist from two halves, a die and the core part. The surface quality of the plastic part is essentially determined by the quality of the matrix material.
Anforderungen an den Matrizenwerkstoff sind:
- gleichmäßig hohe Härte zur Vermeidung von mechanischen Beschädigungen und plastischen Verformungen durch Verkratzen, Verschleiß bei der Kunststoffverarbeitung, Deformation beim Zusammenfahren der Formhälften, Verbiegen und Rißbildung unter Betriebsbedingungen
- gleichmäßige Vergütungsgefügestruktur und hoher Reinheitsgrad zur Sicherstellung einer guten Maschinenbearbeitbarkeit und guter Polier- und fotochemischer Narbeigenschaften.
- uniformly high hardness to avoid mechanical damage and plastic deformation due to scratching, wear in plastics processing, deformation when the mold halves collapse, bending and cracking under operating conditions
- uniform tempered microstructure and high purity to ensure good machinability and good polishing and photochemical scar properties.
Dabei wird die Gebrauchshärte des Formenstahles von ca. 30-40 HRC bereits durch Vergüten des gewalzten oder geschmiedeten Rohlings bei Stahlherstellern eingestellt (vorvergüteter Kunststofformenstahl).Here, the working hardness of the mold steel of about 30-40 HRC is already by tempering the rolled or forged blank at steel manufacturers adjusted (pre-tempered plastic mold steel).
Formen für die Kunststoffverarbeitung werden heute überwiegend aus den Stählen Werkstoff-Nr. 1.2311 und 1.2738 sowie aus AISI P 20 hergestellt (Chemische Analysen siehe Tabelle 1). Molds for plastics processing are today predominantly made of steels Material number. 1.2311 and 1.2738 and made from AISI P 20 (Chemical Analyzes see Table 1).
Für spezielle Anwendungszwecke wie die Verarbeitung von verschleißfördernden, verstärkten Kunststoffen oder Salzsäure abspaltenden Stoffen wie PVC werden darüber hinaus spezielle hochharte (50 - 60 HRC) oder korrosionsbeständige chromlegierte Werkzeugstahllegierungen verwendet.For special applications such as the processing of wear-promoting, reinforced plastics or hydrochloric acid releasing substances such as PVC In addition, special high-hardness (50 - 60 HRC) or corrosion-resistant Chromium-alloyed tool steel alloys used.
Bei der Verwendung herkömmlicher vorvergüteter Kunststofformenstähle besteht ein besonderes Problem in der eingeschränkten Härtbarkeit der Stähle. Die Forderung nach gleichmäßiger Härte im gesamten Volumen der Stahlform erfordert Durchvergütung bis zum Kem des Stahlblockes, unabhängig von dessen Abmessungen.When using conventional pre-tempered plastic molds a particular problem in the limited hardenability of the steels. The requirement after uniform hardness in the entire volume of the steel mold required Through-hardening up to the core of the steel block, regardless of its dimensions.
Die Härtbarkeit der in der Regel ölgehärteten und auf ca. 30 HRC angelassenen Standardstähle AISI P2O, 1.2311 und 1.2738 ist in Bild 1 dargestellt. Daraus geht gleichzeitig die Maximalabmessung für den Einsatz des jeweiligen Stahles hervor, bis zu der noch kein signifikanter Abfall der Härte im Kern, verglichen mit der Randhärte eintritt.The hardenability of the usually oil-hardened and annealed to about 30 HRC Standard steels AISI P2O, 1.2311 and 1.2738 are shown in Figure 1. It goes at the same time the maximum dimension for the use of the respective steel, up to which there is still no significant decrease in hardness in the core, compared to the Edge hardness occurs.
Der Trend der Plastikindustrie zu immer größeren Teilen erfordert ständig größere Formen und entsprechend große Stahlblöcke mit Abmessungen von über 1000 mm Dicke. Für diese Dimensionen sind Blockgewichte von > 50 Tonnen heute üblich.Die dabei zwangsläufig zum Einsatz kommenden großen Schmiedeblöcke mit Gewichten von über 80 to erhöhen seigerungsbedingte Inhomogenitäten, die durch zunehmende Legierungsgehalte weiter verstärkt werden und bei Kunststofformen zu Qualitätsproblemen führen können (Mechanische Bearbeitung, Polieren, Narben). The trend of the plastic industry to ever larger parts requires ever larger Shapes and correspondingly large steel blocks with dimensions of over 1000 mm thickness. For these dimensions, block weights of> 50 tons are today usual. The inevitably used for large forging blocks with weights of over 80 to increase segregation-related inhomogeneities, the be further increased by increasing alloying levels and in plastic molds can lead to quality problems (mechanical processing, polishing, Scar).
In der EP 0 709 481 B1 wird beispielsweise ein Stahl für die in Rede stehende Anwendung vorgeschlagen, der bestimmte Gehalte an Bor aufweist, um die Härtbarkeit zu erhöhen, wobei Aluminium und Titan zur Abschirmung des Bors vor Stickstoff zugegeben werden müssen. Die Verwendung von Bor zur Verbesserung der Härtbarkeit führt jedoch bei größeren Durchmessern zu nicht reproduzierbaren Ergebnissen, d.h. undefinierten Härten insbesondere im Kernbereich.For example, EP 0 709 481 B1 describes a steel for the type in question Application proposed that has certain levels of boron, the hardenability to increase, with aluminum and titanium to shield the borer Nitrogen must be added. The use of boron for improvement However, the hardenability leads to non-reproducible at larger diameters Results, i. undefined hardening, especially in the core area.
Die DE 195 33 229 C1 beschreibt die Verwendung eines ähnlichen Stahles für Druckgasbehälter, die DE 37 28 476 C1 für die Herstellung von Rohren zur Türverstärkung.DE 195 33 229 C1 describes the use of a similar steel for Compressed gas tank, DE 37 28 476 C1 for the production of pipes for door reinforcement.
In der EP 0431 557 B1 ist ein Werkzeugstahl für die Verwendung im Kunststofformenbau beschrieben, der im Hinblick auf gute Schweißbarkeit einen Schwefelgehalt von 0,025 bis 0,10 Gewichtsprozent aufweisen soll. Ferner soll der Werkzeugstahl einer Zusatzbedingung BH = 326,0 + 847,3(C%) + 18,3(Si%) - 8,8(Mn%) - 12,5(Cr%) ≤ 460 genügen, was unter allen Umständen einen Kohlenstoffgehalt von höchsten 0,208 Gewichtsprozent bedeutet. Ein derartig niedriger Kohlenstoffgehalt ist zwar für die Schweißbarkeit von Vorteil, steht jedoch dem Erreichen der geforderten Härten des Werkzeugstahles nach dem Vorvergüten entgegen.In EP 0431 557 B1 is a tool steel for use in Plastic mold described in terms of good weldability Sulfur content of 0.025 to 0.10 weight percent should have. Furthermore, should the tool steel of an additional condition BH = 326.0 + 847.3 (C%) + 18.3 (Si%) - 8.8 (Mn%) - 12.5 (Cr%) ≤ 460, which is a carbon content under all circumstances of the highest 0.208 weight percent. Such a lower one Although carbon content is beneficial for weldability, it is available Achieving the required hardening of the tool steel after pre-tempering opposite.
Die Aufgabe der Erfindung besteht darin, einen Werkzeugstahl für Kunststofformen zu schaffen, der auch bei großen Durchmessern hohe Kernhärten ohne qualitative Nachteile ermöglicht.The object of the invention is a tool steel for plastic molds to create, even with large diameters high core hardness without qualitative Disadvantages enabled.
Erfindungsgemäß wird die Aufgabe durch die Verwendung Werkzeugstahl gelöst,
der die folgende Zusammensetzung (in Gewichtsprozent) aufweist:
Der Werkzeugstahl gemäß den Ansprüchen zur Vermeidung qualitativer Nachteile bewußt ohne Zugabe von Bor hergestellt, wobei die notwendige Härte durch den gezielt eingestellten Nickelgehalt erreicht wird. Überraschenderweise hat sich nämlich gezeigt, daß das fehlende bzw. nur im Rahmen unvermeidlicher Verunreinigungen vorliegende Bor bei sorgfältig eingestelltem Nickelgehalt nicht zu Nachteilen bei den erreichbaren Härtewerten führt, der Stahl gleichzeitig jedoch insbesondere bei größeren Werkstückdurchmessern besser reproduzierbare Ergebnisse in Bezug auf seine Härtbarkeit bei geringerer Neigung zur Versprödung zeigt. Entsprechend braucht auch kein Titan zur Abschirmung des Bors vor Stickstoff zugegeben zu werden.The tool steel according to the claims for avoiding qualitative disadvantages deliberately made without the addition of boron, with the necessary hardness through the targeted set nickel content is achieved. Surprisingly, it has become namely shown that the missing or only in the context of inevitable impurities Boron present at carefully adjusted nickel content not Disadvantages in the achievable hardness values, but the steel at the same time especially for larger workpiece diameters better reproducible results in terms of its hardenability with less tendency to embrittlement shows. Similarly, no titanium is needed to shield the boron from nitrogen to be admitted.
Damit ist der Werkzeugstahl ideal zur Verwendung in Kunststofformen geeignet, insbesondere auch bei größeren Durchmessern des Werkstückes über 400 mm bis zu 1300 mm und darüber.This makes the tool steel ideal for use in plastic molds suitable, especially for larger diameters of the workpiece over 400 mm up to 1300 mm and above.
Durch den vorgesehenen Gewichtanteil an Molybdän zwischen 0,3% und 0,8%, vorzugsweise zwischen 0,4% und 0,6% wird ferner eine verbesserte Anlaßbeständigkeit erreicht, so daß bei einem beispielhaften Werkstückdurchmesser von 1000 mm und einem beispielhaften Gehalt an Mo von 0,5 Gewichtsprozent zum Erreichen von 30 HRC eine Anlaßtemperatur von ca. 620°C vorteilhaft ist, während bekannte Formstähle mit Anlaßtemperaturen deutlich unter 600°C vergütet werden.Due to the intended weight fraction of molybdenum between 0.3% and 0.8%, preferably between 0.4% and 0.6% is further improved Starting resistance reached, so that at an exemplary workpiece diameter of 1000 mm and an exemplary Mo content of 0.5 percent by weight to reach 30 HRC, a tempering temperature of about 620 ° C is advantageous, while known mold steels with tempering temperatures significantly below 600 ° C be tempered.
Der Formenstahl ist ohne Spannungsrißgefahr in Wasser oder Polymer härtbar, weist nur geringe Seigerungen und einen hohen Reinheitsgrad auf und ist infolge der höheren Anlaßtemperatur nach der Wärmebehandlung sehr homogen und eigenspannungsarm.The mold steel is without risk of cracking in water or Polymer curable, has only low segregations and a high degree of purity and is very high due to the higher tempering temperature after the heat treatment homogeneous and low in residual stress.
Zur Verbesserung der Schweißbarkeit kann ein Schwefelgehalt von bis zu 0,15 Gewichtsprozent vorgesehen sein, im Regelfall wird man jedoch zur Sicherstellung eines hohen Reinheitsgrades bemüht sein, den Schwefelgehalt ebenso wie den Gehalt an Phosphor möglichst gering zu halten, beispielsweise S ≤ 0,005% und/oder P ≤ 0,02%.To improve weldability, a sulfur content of up to 0.15 Weight percent be provided, but usually one is to ensure a high degree of purity, the sulfur content as well as to keep phosphorus content as low as possible, for example S ≤ 0.005% and / or P ≤ 0.02%.
In Tabelle 1 und Bild 1 ist ein beispielhaft im Rahmen der
Zusammensetzung gemäß Anspruch 1 hergestellter Formenstahl marktüblichen Stählen gegenübergestellt.
Dabei wurde Kohlenstoff soweit abgesenkt, daß Seigerungen minimiert
werden und gleichzeitig Wasserhärtbarkeit gegeben ist (C max. 0,30 %). Der Siliziumgehalt
wurde zur Minimierung der Blockseigerungen auf einen Durchschnittswert
von 0,1 % abgesenkt, wie auch der Chromgehalt von 2,0 auf 1,25 %.
Weitgehend unverändert geblieben ist der härtbarkeitsfördemde Legierungsgehalt
von Mn (ca. 1,50 %),während der dem Stahl 1.2738 ebenfalls entsprechende Gehalt
an Ni (ca. 1,10 %) in Verbindung mit den sonstigen Gehalten zu den genannten
überraschenden guten Gesamteigenschaften führt. In Table 1 and Figure 1 is an example in the context of
Composition according to
Wegen des bei großen Abmessungen nicht reproduzierbaren härtbarkeitssteigenden Effektes und gleichzeitig versprödender Eigenschaften wurde auf Bor-Zugabe bewußt verzichtet, die Zugabe von Titan kann daher ebenfalls entfallen.Because of the non-reproducible in large dimensions hardenability Effect and at the same time embrittling properties was added to boron deliberately omitted, the addition of titanium can therefore also be omitted.
Die verbesserte Anlaßbeständigkeit wird durch höhere Zugaben von Molybdän
(0,5 % statt ca. 0,20 % bei 1.2738) und Vanadin (0,1 % gegenüber keinem Vanadin
bei 1.2738) eingestellt. Für große Abmessungen über 1000 mm verändern
sich die Anlaßtemperaturen für ca. 30 HRC dabei wie folgt:
Zur Sicherstellung eines hohen Reinheitsgrades wird der Gehalt an Schwefel auf ca. 0,002 % begrenzt.To ensure a high degree of purity, the content of sulfur on about 0.002% limited.
Der Vergleich der Härtbarkeit des Formenstahles gemäß Anspruch mit marktüblichen Standardstählen ist in Bild 1 dargestellt. Danach eignet sich der Stahl für vorvergütete Abmessungen bis ca. 1300 mm ohne qualitative Nachteile.The comparison of the hardenability of the mold steel according to claim Standard steel available on the market is shown in Figure 1. After that is suitable Steel for pre-tempered dimensions up to 1300 mm without any disadvantages.
