Definitions
- the invention relates to a method for producing Components of one of a thermoformable material, especially steel, using existing board a flowable active medium (see, e.g., U.S. Patent No. 5,632,172).
- the object of the invention is a method specify with which complex shaped components under optimized use of the properties of the can be produced.
- the board in one first step partially preformed semi-finished products using flowable active media in one produced suitable forming device.
- this preformed semifinished product is then the final form of the Molded component.
- the preforming takes place only in one limited area of the board. Preforming thus serves unlike, for example, a multi-level Deep drawing of components not intended for training Form elements, which in a further working stroke for It will be shaped as a preform produced in terms of material deformation and distribution and use of the Material properties optimal for the required Properties of the finally produced component is prepared.
- the preform according to the invention only generated in the areas where these are in terms of the geometric (settlement) and / or component-specific properties (strength) required are.
- Requirements may be the pre-deformation of the board without or with the help of a counterform.
- the Preform without counterform has the advantage that the Material of the board during pre-deformation unhindered can flow, so that, for example, an optimized Strength of the preform is achieved.
- the use of a Counterform has the advantage that the preform also optimal in terms of their spatial design can be prepared for the final shape to be generated. This can be a compromise between the free and the complete reshaping in a counterform thereby be found that the preformed portion of the board at the end of the pre-deformation only in a partial area at the Gegenform rests while in the other subarea a free deformation takes place.
- the transformation of the preformed board to the final shape of the Component preferably takes place against one of a Working medium applied support pressure. That way a carefully shaped, exactly shaped, produce high quality component, which due to the gentle processing optimized mechanical Properties and a good visual appearance having.
- the preformed blanks according to the invention can be connected to each other before the final deformation of the component, so that particularly large-area components or components can be manufactured in which the material distribution or the strength of the material present in the areas of the various boards targeted at the practical Use locally each occurring loads of the component are adapted.
- the boards can be material, force and / or positively connected with each other. Alternatively, loosely superimposed boards can be brought together in the final shape after preforming.
- Hollow molds can be with the invention Then make training especially easy if between the superimposed and possibly with each other connected, preformed boards already have a cavity is available.
- the forms thus formed are in particular suitable, by a hydroforming in the final shape the component to be molded, wherein the cavity during the final deformation of the boards to the final shape with high pressure is applied.
- Boards P1, P2 will be the respective board P1, P2 in individual areas B1, V1 and B2, V2 divided. It will distinguished between the area B1 and B2, from the each of the finished deformed component is generated, and the Range V1, V2, in which the pre-deformation of the respective Board P1, P2 is made.
- preforming may also be required the board P2 in a range V2, the in Operababroughen the respective area B2, from which the Component is finished, goes out (Fig. 4).
- the preforming area V2 is also in not provided in this case. Instead, the finds Pre-deformation only takes place where one appropriate preparation of the board P1 or P2 for the subsequent finished shapes appropriate and necessary is.
- the number of for the Preforms do not include one limited, but it may, if necessary, several determined such preform areas on a board become.
- subdivided board P4 Forming U1, U2 used for pre-forming the board P1 or a corresponding the board P2 in a vorzuverformenden area and an area from which the final shape of the produced Component is generated.
- a liquid active medium For example, water, filled container 1 on.
- the forming devices U1, U2 are each with a holding device 2, which each preformed board P1, P4 in their edge regions hold the edge surrounding an opening of the container 1.
- the board P1 or P4 is above the Opening tensioned, so that their the container interior assigned side are acted upon with the active medium can.
- the course of the edge of the opening of the container. 1 corresponds in each case to the course of the edge of the the preforming provided area V1 and V2 of each processed board P1, P4.
- the Preforming the board P1 is done without counterform, is the Forming device U2 equipped with a counter-mold 3, the distance from the opening in this example the container 1 tensioned board P4 is arranged.
- the preforming of the boards P1 - P4 also be performed in a device F2, which a container 20 for an active medium 21, in particular Water, and a holding device 22 has.
- the Holding device 22 is for example the preformed Board P1 held in the opening of the container 20.
- the finished molding of the board P1 is then done by means a punch 23, which in the opening of the container 20th is insertable and in the end face the shape of the forming component is formed.
- a punch 23 At a work stroke of the punch 23 is the preformed board P1 in the Container 20 pulled. In doing so, this exercises in the container 20 contained active medium one of the force of the punch 23rd opposing support pressure S, so that the preformed board P1 with increasing stroke of the Stamp 23 puts on these and so on by the stamp 23 given form.
- the pre-formed hollow bodies H1, H2 can be particularly well finished by applying pressure to hydroforming.
- the hollow body H1, H2 in a die a suitable device, not shown here positioned and with a flowable active medium, for example, water, filled.
- a flowable active medium for example, water
