Definitions
- the invention relates to a method for shaping and hardening steel materials.
- Hardened steel components have the advantage in particular in car body of motor vehicles that, by their outstanding mechanical properties is a possibility to create a particularly stable passenger cell, without construction ⁇ parts must be used, which are formed in normal strength much more massive and thus heavy become.
- steel grades which are curable by quench hardening are used.
- Such types of steel are, for example, boron-alloyed manganese boron steels, the most widely used one being 22MnB5. But other boron-alloyed manganese carbon steels are also used for this purpose.
- the steel material In order to produce the components hardened from these steel grades, the steel material must be heated to the austenitizing temperature (> AC 3 ) and allowed to stand until the steel material is austenitized. Depending on the desired degree of hardness partial or full austenitisings can be achieved here.
- the device thus produced is then austenitized and then inserted into a shape hardening tool, in the pressed it, but is converted into very low and the heat from the component flowing through the pressure in the pressing tool, with the above the critical Härtegeschwindig ⁇ not or speed.
- press hardening in which a board separated from a steel strip bsp. From ⁇ cut or punched, then the board is made ⁇ tenitinstrument and the hot platinum at a temperature below 782 ° C in a preferably single-stage step umge ⁇ formed and cooled simultaneously with a velocity lying above the critical speed.
- Form hardening is also referred to as an indirect process and press hardening as a direct process.
- the advantage of the indirect process is that more complex workpiece geometries can be realized.
- the advantage of the direct process is that a higher degree of material utilization can be achieved. However, the achievable component complexity is lower, especially in the single-stage forming process.
- From DE 10 2004 054 795 B4 discloses a process for manufacture of vehicle components, as well as body parts, be ⁇ known, wherein a material composite of two verbun ⁇ which sheet is subjected to at least one forming operation with each other, whereby the material composite hot formed and at least one curable prealloyed Sheet metal is subjected to in situ press hardening with the mold halves closed.
- a schiroch horrumformver- is driving, in which a hollow structure made of hardenable steel ⁇ blechen is expanded through a gas under pressure, which flows into the inner space between the sheets, wherein the work ⁇ piece in a is cooled forming tool and the workpiece is formed in one go by the pressure of the gas and formed by the temperature of this gas from the inside and the temperature of the forming tool from the outside in the same tool and hardened, the gas pressure in the workpiece by Rela ⁇ tive movement of a press upper part and Flow direction of the mold is generated and amplified by a pressure intensifier.
- DE 10 2007 043 154 A1 discloses a method and a device for hardening profiles.
- This method is designed in particular for open profiles, wherein the member is heated at least in partial areas to a temperature above the austenitizing temperature of the base material and the component after the heating at a velocity is cooled ness, which is above the critical Härtegeschwindig ⁇ ness, wherein the for the heating necessary energy ⁇ at least partially introduced by induction, wherein in the component for setting a temperature and / or hardness ⁇ gradients over the cross section of the component free edges are arranged, wherein size, type and extent of the edges on a desired degree of hardness and / or hardness gradients render ⁇ be arranged.
- These edges have the effect that edges on inductive heating increase the current density, so that heating in these areas can be carried out very quickly, at least faster than in flat areas.
- the object of the invention is to provide a method for forming and hardening of galvanized steel pipes, with the zuver ⁇ casual and crack-free hardened steel pipes can be produced.
- galvanized pipes were considered to be non-microcrackable and hardenable without hydroforming. Be the ⁇ like galvanized pipes or pipe components by internal high pressure forming ⁇ , there are always microcracks in very large scale, so unlike other molding processes, the press ⁇ curing process or mold hardening process for metal components was not applicable.
- the inventors have recognized that the micro-crack free forming pipe components succeeds when it performs a special Tempe ⁇ temperature and process control.
- such pipe components are prefabricated and vorgebo ⁇ gen analogous to the known hydroforming process, pre-squeezed or preformed in any other way.
- these tubes are austenitized, which means that they are brought to a temperature above AC 3 and held there until a desired Austeniti- stechniksgrad is achieved.
- the tube is then allowed to passively cool to temperatures between 400-650 ° C. or forcibly actively cooled. This cooling can take place in that the component is transferred into the hydroforming and thereby cools passively in air or, optionally, the tool according to the training tenitmaschinesofen for example by blowing or claims ⁇ hen actively cooled with suitable cooling media, and is then transferred into the hydroforming.
- Such active cooling is performed with> 5 K / sec preferably> 10 K / sec more preferably> 20 K / sec Abkühlgeschwindig ⁇ ness.
- the tube is end-formed, wherein a medium under pressure is pressed into the tube, so that a known internal high-pressure forming is achieved.
- this transformation is performed with a tempe ⁇ tured medium.
- the medium has, for example ⁇ a temperature of 400-650 ° C.
- the invention has in fact been found to be already subjected to when using a kal ⁇ th medium parts of the pipe subjected to curing before the final forming takes place. This signified tet ⁇ that complete formation is prevented.
- the forming takes place with a temperature-controlled medium, where ⁇ in the tempered medium preferably a temperature be ⁇ sitting, which corresponds to the temperature of the tube to be formed and at least so high that the martensite start temperature (Ms) of the steel alloy used is exceeded.
- Ms martensite start temperature
- the internal high-pressure forming is performed in a hot tool with the warm un ⁇ ter pressurized forming medium. Subsequently, the so um ⁇ shaped component is removed from the tool and passively allowed to cool in air, when the cooling in air is sufficient, the critical cooling rate of the steel material to errei ⁇ chen, so that a martensitic curing is ensured.
- This passive cooling is primarily sheet thickness-dependent on thinner sheet thicknesses of about 1 mm from a passive cooling ⁇ can of air to be sufficient to achieve the critical Abkühlge ⁇ speed.
- a second variant of the invention is in turn converted in the warm tool with the warm pressurized medium and subsequently transferred to the tube in a cold mold hardness ⁇ tool.
- this cold form hardening tool ent ⁇ the die cavity from the contour forth speaks exactly the Au ⁇ hkontur of the pipe, so that the tool is present on all sides on the pipe over the entire surface during the closing of the tool and thereby a quench hardening is obtained.
- Cold in the sense of the invention means that the martensite starting temperature of the selected steel material is at least 50 ° C below, ie Ms - 50 ° C.
- the order ⁇ modeling in the warm tool with the aid of the pressurized heated Umformmediums is carried out, the order ⁇ modeling in the warm tool with the aid of the pressurized heated Umformmediums, but after forming a cold medium is passed through the tube so that the martensitic hardening by exceeding the kriti ⁇ rule quenching by the cooling is achieved with the cal ⁇ th medium.
- the warm gaseous medium it is technologically possible to be under pressure ⁇ the warm gaseous medium to carry out the internal high with one and the ex ⁇ scary process with a cold gaseous medium, but also with a liquid cold medium.
- the temperature of the cold medium is preferably the martensite start temperature of the material, ie Ms - 50 ° C.
- the pipes generally have an inlet and a drain.
- tubes in the context of the invention not only cylindri ⁇ cal tubes are understood, but any form of elongated hollow bodies made of sheet steel, in particular structural components, side members, reinforcements, sills and the like Struk ⁇ tur turbines, especially of motor vehicles.
- a material which is curable, such as the materials of the prior art and re insbesonde ⁇ a curable boron manganese steel such as a steel material of the type 22MnB5 or 20MnB8 or comparable.
- Such steel sheets may be provided with a zinc layer, a zinc alloy layer and, in particular, a zinc iron layer.
- a so-called galvannealed coating is preferred, ie, a pre-reacted by tempering zinc coating on a steel sheet, which consists of zinc-iron phases and also resistant to the injection of a pressure medium.
- the invention is exemplified erläu ⁇ tert reference to a drawing.
- the single figure shows the procedure with the two variants of the method.
- An austenitized tube 1 1 is in this case placed a ⁇ into a mold 2, the tube 1 is to be ⁇ sammenform example, of two plates 3, wherein the plates in the area of a Gaszuept ⁇ tion and discharge to a space formed by the sheets hollow ⁇ space 4 each has a corresponding access 5.
- tem ⁇ perêts gas heated to 400-650 ° C, for example, gas is filled into the cavity 4, the pipe 1 is expanded in the mold 2, so the fully preformed green body is produced.
