Abstract

The invention relates to a method for producing the vehicle floor (1) of a mine-protected vehicle, wherein the vehicle floor (1) consists of a plurality of individual sheets (11-17) of armour steel connected to one another. The invention further relates to a vehicle floor (1) produced according to the method of the invention. In order to easily prevent the vehicle floor (1) from being torn open in the area of weld seams in the event of a mine explosion, the invention proposes the use of tailored blanks (10) made of armour steel, from which the contour of the respective vehicle floor (1) can then be produced by cold or hot forming. Normalised individual sheets (11-17) of appropriate wall thicknesses, which are connected to one another by means of laser beam welding, are used to produce the tailored blanks (10). These tailored blanks (10) are hardened and tempered only after the welding process and the final vehicle floor (1) is then produced by forming.

Description

BESCHREIBUNG  DESCRIPTION
Verfahren zur Herstellung des Fahrzeugbodens eines minengeschützten Method for producing the vehicle floor of a mine-protected
Fahrzeuges  vehicle
Die Erfindung beschäftigt sich mit einem als Tailored Biank ausgeführten Fahrzeugboden für ein insbesondere minengeschütztes Fahrzeug und betrifft ein Verfahren zur Herstellung des Fahrzeugbodens eines minengeschützten Fahrzeuges, wobei der Fahrzeugboden aus mehreren, miteinander verbundenen Einzelblechen aus Panzerstahl besteht. Die Erfindung bezieht sich ferner auf einen nach dem erfindungsgemäßen Verfahren hergestellten Fahrzeugboden. Wesentlich hierbei ist, dass zunächst das Verschweißen der Einzelbleche erfolgt, dem sich das Umformen anschließt mit dem abschließenden Vergüten, Eine Alternative besteht in einer Kombination aus Umform- und Vergütungsprozess. The invention relates to a designed as Tailored Biank vehicle floor for a particular mine protected vehicle and relates to a method for producing the vehicle floor of a mine-protected vehicle, wherein the vehicle floor consists of several, interconnected individual sheets of armored steel. The invention further relates to a vehicle floor produced by the method according to the invention. It is essential here that the individual sheets are initially welded, followed by the forming followed by the final tempering. An alternative consists of a combination of forming and tempering process.
Fahrzeugböden minengeschützter Fahrzeuge müssen derart aufgebaut sein, dass einerseits ein Aufreißen des Fahrzeugbodens im Falle einer Minenexplosion verhindert wird und andererseits die durch eine Minenexplosion verursachten Beulen im Fahrzeugboden die vorhandenen Einbauten im Fahrzeug nicht beschädigen. Außerdem muss der Fahrzeugboden Schutz gegen ballistische Bedrohungen bieten, und zwar zum einen gegen Splitter explodierender Minen und zum anderen gegen einen Waffen beschuss, insbesondere im Übergangsbereich des Fahrzeugbodens zur Fahrzeugseite. Vehicle floors of mine-protected vehicles must be designed such that on the one hand tearing of the vehicle floor in the event of a mine explosion is prevented and on the other hand caused by a mine explosion bumps in the vehicle floor damage the existing fittings in the vehicle. In addition, the vehicle floor must provide protection against ballistic threats, on the one hand against splinters exploding mines and on the other hand against a weapons firing, especially in the transition region of the vehicle floor to the vehicle side.
Bei bekannten Fahrzeugböden minengeschützter Fahrzeuge werden vergütete Einzelbleche aus Panzerstahl üblicherweise mit Hilfe eines M IG- Verfahrens (Metall-Inert-Gas- Verfahren) verschweißt, wobei die teilweise unterschiedliche Wandstärken aufweisenden Einzelbleche sich im Bereich der Schweißnaht überlappen. Derartige Schweißnähte bilden Schwachstellen, da sie eine geringere Festigkeit als der Panzerstahl aufweisen. Außerdem kommt es durch das Schweißverfahren in der jeweiligen Wärmeeinflusszone zur Versprödung des Materials, sodass diese Bereiche bei einer Minenexplosion besonders rissanfäliig sind. Aus der EP 1 564 520 A2 ist es daher bekannt, die Schweißnähte samt deren Wärmeeinflusszonen durch Schutzbleche zu überdecken, was allerdings sowohl mit einer Zunahme des Gewichtes als auch mit einem zeitaufwendigeren Fertigungsprozess des entsprechenden Fahrzeugbodens verbunden ist. In the case of known vehicle floors of mine-protected vehicles, tempered individual steel sheets made of armor steel are usually welded by means of a MIG process (metal inert gas process), the individual sheets having partially different wall thicknesses overlapping in the region of the weld seam. Such welds form weak points, since they have a lower strength than the steel armor. In addition, the welding process in the respective heat affected zone embrittles the material, so that these areas are particularly susceptible to cracking in a mine explosion. From EP 1 564 520 A2 it is therefore known to cover the weld seams together with their heat affected zones by protective sheets, which however is associated both with an increase in weight and with a more time-consuming production process of the corresponding vehicle floor.
Die EP 1 291 610 B1 beschäftigt sich mit einem gepanzerten Fahrzeug, das durch einfache Maßnahmen einen Schutz des Innenraumes gegen eine Einwirkung von Minen gewährleistet. Dazu ist der Bodenbereich einer Seitenwandausnehmung des Innenraums über mindestens ein knick- oder bausteifes Stützelement mit dem Fahrzeugdach verbunden. Der Rand einer Bodenwand des Bodenbereichs verläuft gekrümmt nach oben und überlappt einen Wandbereich der Fahrzeugseätenwand, der mit einem arideren Wandbereich verschweißt ist. Dieser besitzt einen wellenförmigen Verlauf. Dadurch soll ein Reißen der Schweißnaht verhindert werden. EP 1 291 610 B1 deals with an armored vehicle which, by simple measures, ensures protection of the interior against the action of mines. For this purpose, the bottom region of a side wall recess of the interior is connected to the vehicle roof via at least one kink-like or structural support element. The edge of a bottom wall of the bottom portion is curved upward and overlaps a wall portion of the vehicle body wall which is welded to a different wall portion. This has a wavy course. This is to prevent tearing of the weld.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs erwähnten Art anzugeben, mit dem auf einfache Weise bei einer Minenexplosion ein Aufreißen des Fahrzeugbodens im Bereich von Schweißnähten vermieden wird, ohne dass hierzu eine Verstärkung der Schweißnahtbereiche mittels zusätzlicher Bleche erforderlich ist. Es soll ferner ein nach diesem Verfahren hergestellter Fahrzeugboden offenbart werden. The invention has for its object to provide a method of the type mentioned above, with a simple way in a mine explosion tearing of the vehicle floor in the region of welds is avoided without requiring a reinforcement of the weld seams by means of additional sheets is required. It should also be disclosed by this method produced vehicle floor.
Diese Aufgabe wird erfindungsgemäß hinsichtlich des Verfahrens durch die Merkmale des Anspruchs 1 und hinsichtlich des Fahrzeugbodens durch die Merkmale des Anspruchs 3 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche. This object is achieved with respect to the method by the features of claim 1 and with respect to the vehicle floor by the features of claim 3. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
Die Erfindung beruht im Wesentlichen auf dem Einsatz von Tailored Bianks. Beim Tailored Welded Blank (TWB) werden die einzelnen, vorzugsweise maßgeschneiderten Blechplatinen aneinandergeschweißt. Dies erfolgt in der Regel als Stumpfstoß mittels Laserschweißen. Vorteilhaft sind die vielseitigen Materiaikombinationen und Geometrien. In Weiterführung bestehen diese aus Panzerstahl, aus denen die Kontur des jeweiligen Fahrzeugbodens dann durch Kalt- oder Warmumformung hergestellt wird. Zur Herstellung der Tailored Bianks werden normalgeglühte Einzelbleche entsprechender Wandstärken verwendet, die mittels Laserstrahlschweißens miteinander verbunden werden. Einen derartigen Ansatz für die Automobilindustrie ist u.a. der http://www.thyssenkrupptai!oredblanks.it default.asp?page=8&titolo=1 oder der http://vAA w^hvssenkrupptaiioredblanks.it/default.asp?page=2&titolo=1 entnehmbar. The invention is based essentially on the use of tailored bianks. With the Tailored Welded Blank (TWB), the individual, preferably tailor-made sheet metal blanks are welded together. This is usually done as a butt joint by laser welding. Advantageous are the versatile combinations of materials and geometries. In continuation, these consist of armored steel, from which the contour of the respective vehicle floor is then produced by cold or hot forming. For producing the tailored bianks, normalized individual sheets of appropriate wall thicknesses are used, which are connected to one another by means of laser beam welding. Such an approach for the automotive industry is the http: //www.thyssenkrupptai! oredblanks.it default.asp? page = 8 & titolo = 1 or the http: // vAA w ^ hvssenkrupptaiioredblanks.it / default.asp? page = 2 & titolo = 1 removable.
Die Taiiored Bianks werden für das eigene Anliegen der Erfindung jedoch erst nach dem Schweißvorgang vergütet und danach wird dann der endgültige Fahrzeugboden durch Umformung hergestellt. The Taiiored Bianks are tempered for their own concern of the invention, however, only after the welding process and then then the final vehicle floor is made by forming.
Durch das Vergüten nach dem Schweißen, vorzugsweise dem besagten Laserschweißen, entsteht ein nahezu homogener Übergang zwischen den Blechen, wodurch eine Schwächung durch späteres Schweißen vermieden wird. Zugleich wird es einfacher, Bleche unterschiedlicher Dicke und / oder Güte miteinander zu kombinieren, sodass sich ein Gewichtseinsparungspotential ergibt, auch dadurch, dass Überlappungen vermieden werden und die minimal nötigen Blechdicken an der richtigen Stelle eingebunden sind. By annealing after welding, preferably the said laser welding, a nearly homogeneous transition between the sheets, whereby a weakening is avoided by subsequent welding. At the same time, it is easier to combine sheets of different thickness and / or quality with each other, so that there is a potential for saving weight, also in that overlaps are avoided and the minimum required sheet thicknesses are involved in the right place.
Das Vergüten ist als Prozess eine Wärmebehandlung wie bei Stählen hierbei bevorzugt, also eine Kombination aus Härten und Anlassen. Beim Härten von Stählen wird zunächst bei Temperaturen oberhalb Ac(3) der Kohlenstoff im Austenit gelöst und anschließend auf Temperaturen unterhalb M{s) bzw. M(f) abgeschreckt. Das Anlassen ist dann ein erneutes Erwärmen nach dem Abschrecken auf Temperaturen unterhalb Ac(1 ), um eine Umwandlung in kubischen Martensit, sowie die Ausscheidung feiner Karbide und ggf. weitere Koagulation dieser Partikel zu erreichen. As a process, heat treatment is preferred as a heat treatment as in steels, ie a combination of hardening and tempering. When hardening steels, the carbon is first dissolved in austenite at temperatures above Ac (3) and then quenched to temperatures below M {s) or M (f). Tempering is then reheating after quenching to temperatures below Ac (1) to achieve conversion to cubic martensite, as well as the precipitation of fine carbides and optionally further coagulation of these particles.

In Fig. 1 ist mit 1 ein erfindungsgemäßer Fahrzeugboden {Fahrzeugwanne) und / oder Zwischenboden eines nicht näher dargestellten minengeschützten Fahrzeuges dargestellt, der im Wesentlichen zwei U-förmige Abschnitte 2 und 3 aufweist. Die beiden U- förmigen Abschnitte 2, 3 umfassen jeweils einen äußeren Schenkel 4 und einen inneren Schenkel 5, wobei die beiden inneren Schenkel 5 der U-förmigen Abschnitte 2, 3 einen tunnelförmigen Abschnitt 6 bilden. Fig. 2 shows a longitudinal section through a sheet metal plate (Taiiored Blank), which is composed of individual sheets of different wall thickness, for the production of the vehicle floor shown in Fig. 1. 1 shows an inventive vehicle floor {vehicle pan) and / or intermediate floor of a mine-protected vehicle (not shown in more detail), which has essentially two U-shaped sections 2 and 3. The two U-shaped sections 2, 3 each comprise an outer leg 4 and an inner leg 5, the two inner legs 5 of the U-shaped sections 2, 3 forming a tunnel-shaped section 6.
Bei dem aus bevorzugt Panzerstahl bestehenden Fahrzeugboden 1 ist nun vorgesehen, dass der in den Fahrzeuginnenraum eines nicht dargestellten minengeschützten Fahrzeuges ragende tunnelförmige Abschnitt 6 eine Wandstärke von beispielsweise 10 mm und die Bodenabschnitte 7 zwischen den beiden Schenkeln 4, 5 der U-förmigen Abschnitte 2, 3 jeweils eine Wandstärke von 12 mm besitzen, da sie bei einer Minenexplosion besonders stark von deren Druckwelle betroffen sind und außerdem den Fahrzeuginnenraum des entsprechenden Fahrzeuges vor Splitter schützen sollen. In the preferred consisting of armored steel vehicle floor 1 is now provided that the projecting into the vehicle interior of a mine-protected vehicle not shown tunnel-shaped portion 6 has a wall thickness of for example 10 mm and the bottom portions 7 between the two legs 4, 5 of the U-shaped sections 2, 3 each have a wall thickness of 12 mm, since they are particularly affected in a mine explosion of the pressure wave and also to protect the vehicle interior of the corresponding vehicle from splinters.
Die äußeren Schenkel 4 der beiden U-förmigen Abschnitte 2, 3 setzen sich aus jeweils zwei Teilabschnitten 8, 9 zusammen. Dabei weist der erste Teilabschnitt 8 ebenfalls eine Wandstärke von beispielsweise 12 mm und der sich anschließende zweite Teilabschnitt 9 eine Wandstärke von 15 mm auf, da der Teilabschnitt 9 besonders durch direkten Besch uss gefährdet ist. The outer legs 4 of the two U-shaped sections 2, 3 are composed of two sections 8, 9 together. In this case, the first section 8 also has a wall thickness of for example 12 mm and the subsequent second section 9 has a wall thickness of 15 mm, since the section 9 is particularly endangered by direct Beschus.
Fig. 2 zeigt den Längsschnitt durch eine mit dem Bezugszeichen 10 bezeichnete Blechplatine (Tailored Blank) vor dem Umformen bzw. nach dem Verschweißen bzw. Vergüten, aus der der erfindungsgemäße Fahrzeugboden 1 (Fig. 1) durch Umformen hergestellt wird. 2 shows the longitudinal section through a sheet-metal blank (designated blank) designated before the forming or after welding or tempering, from which the vehicle floor 1 according to the invention (FIG. 1) is produced by forming.
