Definitions
- the invention relates to a method and an apparatus for producing hardened steel components.
- Hardened steel components have the advantage in particular in car body of motor vehicles that, by their protruding ⁇ mechanical properties, there is a way 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 steels are, for example, boron-alloyed manganese carbon steels, with the most widely used, here 22MnB5. But other boron-alloyed Mangankoh ⁇ lenstoffstähle be used for this purpose.
- the steel material must be heated and to wait until the steelworks ⁇ material is austenitized to the austenitizing temperature (> AC 3). 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.
- ⁇ layers for example be used with zinc or an alloy based on zinc boards provided with metallic corrosion protection.
- 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 that a higher Mate ⁇ rialversgrad can be achieved.
- the goal of reaching ⁇ cash component complexity is lower, especially the single-stage process Umformpro-.
- microcracks are formed in the surface.
- first-order microcracks and second-order microcracks.
- Microcracks of the first order are attributed to the so-called liquid metal embrittlement.
- Liquid zinc phases are thought to interact with remaining austenite phases during forming, ie, while tensile stresses are being applied to the material, creating microcracks with depths of up to several hundred microns in the material.
- the applicant has succeeded by active or passive cooling of the material between removal from the Erhitzungs ⁇ oven and before the start of Warmumformvorgangs on tempera ⁇ reindeer, where no liquid zinc phases are left, to stop these microcracks first order. This means that hot working takes place at temperatures below about 750 ° C.
- the second order microcracks to date in the Warmumfor ⁇ tion despite pre-cooling can not be controlled and are also formed in Warmumformtemperaturen below 600 ° C.
- the crack depths here are up to several 10 pm.
- Neither microcracks first order still microcracks second Ord ⁇ voltage be accepted by the users, as this is a Moegli ⁇ che source of damage.
- a production of components can not be backed up without Darge ⁇ microcracks second order.
- the die used for hot forming and press hardening should be liquid coated in its defined by a positive drawing radius Ziehkanten Society with a material material or be provided with an insert which has a thermal conductivity which is lower by at least 10 W / (mx K) than the thermal conductivity of the drawing edges ⁇ area adjacent section of the die which comes into contact during Warmum ⁇ forming and press hardening of the work piece with the same.
- the workpiece-facing surface of the material applied in the draw ⁇ edge region or the arranged Einsat zers should have a extending over the drawing edge transverse dimension, which is in the range of 1.6 times to 10 times the positive drawing radius of the die. This makes the flow characteristics of workpieces made of sheet steel is to be improved during the hot forming and thus the risk of occurrence of cracks during hot forming of work pieces made of sheet steel, preferably galvanized steel plates, are fixed ⁇ Lich reduced. With such a tool, however, microcracks of the second kind can not be avoided.
- micro-cracks of the second type are corresponds when entering tensile-strained areas occurring zinc ⁇ vapor in sufficient concentration to the steel, so- ⁇ -called Vapor metal embrittlement (VME).
- VME Vapor metal embrittlement
- Zinc vapor is formed by tearing the zinc iron layer during stretching during the forming process.
- Sufficient concentration occurs in particular in those areas in which direct contact of the sheet with the tool prevails or there is a very small distance between the sheet and the tool.
- a very small distance in the sense of the invention is less than 0.5 mm.
- the zinc vapor occurs either by gas streams ⁇ in the tensile-strained regions (Deh ⁇ voltage rand fiber) (convection) is discharged or blown off or sufficiently diluted.
- gas streams ⁇ in the tensile-strained regions (Deh ⁇ voltage rand fiber) (convection) is discharged or blown off or sufficiently diluted.
- by access Of zinc fluids are rapidly converted into a stable compound such as zinc oxide or ZnJ2.
- protection of the steel against second order microcracks can also be achieved by creating a protective layer such as an oxide layer by supplying a fluid. All measures described have ever ⁇ shown wells that microcracks are significantly reduced.
- gaseous oxygen-containing fluids such as air or oxygen, as these may not unduly contaminate the tool or a allvert ⁇ celled unwanted massive cooling effect as Ex. Water can be easily regulated by tempering the fluid.
- microcracks of the second order is ensured here by the fact that in the region of the positive radii, ie in the region of the drawing edges of the matrix and / or the patrix in the drawing direction, there is a cutout following the drawing edge or other contact regions outside the positive radii / pulling edge is, which is dimensioned so that on the one hand, the deep drawing is not affected or the board or the workpiece is wavy and on the other hand so di ⁇ dimensioned that the heat dissipation, which is necessary for curing, also not significantly affected.
- the recesses but are dimensioned so that they constitute a Reser ⁇ voir for oxygen so that sufficiently acidic ⁇ material to which pulling board or the material passes in order to supply liberated zinc phases or zinc iron phases for the oxidation with oxygen.
- the cutout acts as a fluid reservoir especially for Sau ⁇ erstoff, but this reservoir may be other fluids contained ⁇ th, such as water or nitrogen. If these are filled with a noble gas or even in particular continuously be washed with, they do not act by oxidation but by dilution or removal of the occurring zinc vapor.
- the recesses can be fed advantageously tool side during the forming process continuously with oxygen-containing fluids, for example, by ge ⁇ suitable access openings, wherein advantageously capable of forming a Strö ⁇ mung pillow.
- the tool cavity can be rinsed after forming a workpiece and before inserting another board with a particular oxygen-containing fluid, which is then present in the recesses ⁇ .
- an oxygen-containing fluid is air than water and that these can be fed in liquid or gaseous ⁇ shaped.
- the invention is exemplified erläu ⁇ tert reference to a drawing. It shows:
- Figure 1 shows the tool area, adjacent to a pulling edge with an exemption according to the invention
- FIG. 2 shows the pulling edge portion of a tool with a white ⁇ more advanced embodiment of the exemption of the invention
- 3 shows the drawing edge region of a tool with a he ⁇ inventive slot arrangement in a partially sectioned side view
- Figure 4 shows the arrangement of Figure 3 in a plan view.
- the pulling edge region 1 or region of a positive radius 1 is arranged on a molding tool and has two workpiece-side surfaces 3, 4, which meet in the region of a drawing edge or a positive radius 2.
- the drawing edge 2 in the drawing direction subsequent surface 4 a cutout 5 according to the invention is arranged.
- the cutout 5 is dimensioned such that the remaining thickness of the de drawing edge 2 between the surface 3 and the Freis ⁇ Parung 5 corresponds approximately to its radius in order to provide an adequate supporting effect for the material to be drawn.
- the cutout 5 has between the pulling edge 2 and the surface 4 has a height which is approximately 25 to 35 mm, at ei ⁇ ner depth of 5 to 9 mm.
- Figure 2 is instead of a large-scale cutout 5 adjacent to the drawing edge 2, and this belas ⁇ send in already described strength, in the surface 4, a groove 6 is introduced.
- the groove 6 be ⁇ sits a height between the surface 4 and the drawing edge 2, which is approximately 8 to 12 mm, at a depth of 5 to 9 mm.
- a Runaway ⁇ Henden cutout 5 has a plurality of extending in the drawing direction Nu ⁇ th 7 adjacent in the area of the wall 4 is provided to the pulling edge 2, wherein the grooves or slots 7 7 beispiels- example, have a slot width of 4 to 8 mm and a Schlitzab ⁇ stand of 7 to 11 mm, so that the remaining Ste ⁇ ge have a width of 1 to 5 mm.
- the grooves 7 and slots 7 here also have a depth of 5 to 9 mm.
- the recesses 5, the groove 6, the slots 7 back ie by the tool, by means of feeds and correspondingly drilled lines with an oxygen-containing fluid ver ⁇ provides, if necessary, the oxygen partial pressure in the region of the recesses 5, grooves 6 and 7 slots still increase.
