Definitions
- the invention relates to a process for the production of structural components from an extruded profile, in particular consisting of aluminum (Al), magnesium (Mg), or their alloys, which after emerging from the die of the extrusion press for the purpose of forming it as a straight or curved (rounded) Profile is guided by one or more guide tools, after which an end section is cut off with a cutting tool and fed to one or more further processing stations in succession.
- an extruded profile in particular consisting of aluminum (Al), magnesium (Mg), or their alloys
- an essential proposal according to the present invention is that after a section of the extruded profile has been cut off by means of a separating tool, the extruded profile in the hot state is fed to a hot-forming process by means of gripping tools. This step ensures that the heat of the hot strand is retained for the downstream hot-forming process, components which are ready for installation being able to be produced as a result of this hot-forming process.
- the working window that is suitable for the forming temperature can be realized with optimal forming capacity for aluminum or magnesium or for aluminum / magnesium alloys without additional energy expenditure or without great energy expenditure, for example by cooling the workpiece.
- a particular advantage of the method according to the invention is that it offers the possibility of accepting lower accuracy requirements with regard to the contour of the extruded profile, since the hot-forming step can simultaneously be used for calibration in order to achieve the exact shape of the finished structural component.
- An additional advantage of the method according to the invention is that by including the Process step of hot forming an increase in added value is made possible by the fact that in the same process step further design features of the end product can be realized such as the introduction of holes, the creation of small shapes or the like.
- the extrusion speed can be increased, making it possible to use the extrusion system, which is expensive to purchase.
- Al and Mg semi-finished parts are connected to one another by means of friction stir welding to form new structural components. This can expediently take place in a welding and machining center, which is arranged after the hot curing process that follows the hot-forming process.
- the joining of Al and Mg components by gluing can be considered. It should be noted here that the adhesive components after hot forming process are applied so that the final strength is achieved in the subsequent heat curing.
- the forming process is that the extruded profiles are processed further in an IHU step (hydroforming).
- the associated high tool costs often speak against the use of the IHU process, which is desirable because of its accuracy.
- the IHU is always designed as a cold forming process for calibrating AI components; Mg components, on the other hand, are advantageously a hot-forming process. In this way, the formation of an unfavorable hexagonal metal grid structure is avoided for the first time.
- Forging should be considered as a much cheaper forming process; a hot stamping step is also possible, which is more accurate than forging. A sequential sequence of both methods may also be advantageous.
- the hot forming process also includes a calibration step which, for example, follows the forging.
- the hot forming temperature or, before other processing stations the processing temperature is set by cooling the workpiece to the optimum temperature for the respective alloy of the workpiece to be produced.
- this advantageously means the setting of a hot forming temperature of 180 ° C to 400 ° C. preferably 225 ° to 280 ° C.
- a suitable temperature for hot forming after extrusion is below 200 ° C.
- the cooling of the extruded profile is expediently to be carried out in such a abrupt manner that there are no Mg 2 Si precipitates in a temperature range from 520 ° C. to 200 ° C.
- the subsequent hot-forming step must then be carried out in the shortest possible time in order to utilize the full formability of this material here, too, before the material is hardened by Mg 2 Si precipitates.
- the hot forming temperature between 300 ° C and 600 ° C, preferably between 400 ° C and set 520 ° C; If an embossing step is provided, it is expedient to set the forming temperature rather at the upper limit of the temperature range mentioned, that is to say close to 600 ° C.
- further processing stations can be connected to the hot forming process in the processing of Al and Mg structural components, preferably hot curing in the heating furnace and then various mechanical processing stations, the workpiece being able to be cooled in an upstream cooling zone before the hot curing.
- the cooling zone can also be provided before the hot forming process. This applies in particular to the processing of hardenable wrought aluminum alloys. As already expressed above, this is about avoiding undesirable structural hardening by Mg 2 Si precipitates.
- the guiding robots have a guiding device which is movable in a plane perpendicular to the pressing plane and / or rotatable about its longitudinal axis. It is used to deform the extruded profile within a plane with a constant or variable radius and to twist the profile around its longitudinal axis.
- the cycle times with which the process and processing steps follow one another are significantly adapted to the respective extrusion speed. Accordingly, the invention provides that for the production of Al structural components after extrusion, a multiplication, e.g. a doubling of the manufacturing chain required for Mg structural components is established. This results as a result of significantly higher extrusion speeds for aluminum components (up to 25 m / min) compared to magnesium components (up to 1.5 m / min).
- the invention provides that at least one guide robot is path-controlled depending on the press path of the extruded profile and the respective curvature profile, the press path being attached directly to the emerging strand by means of a robot on the guide robot Sensor device can be measured.
- the extruded profile is deformed by the guide robot and expediently supported by a handling robot in order to be finally cut to length by a cutting robot.
- an outlet table can also be sufficient for support.
- only one guide robot may be required for the manufacturing process according to the invention, which takes over the rounding of the extrusion profile emerging straight from the extrusion press and simultaneously supports it.
- straight as well as arbitrarily curved components can be produced.
- at least two guide robots are useful.
- Robot technology requires a particularly large effort for the production of spatially rounded extruded profiles with variable curvature.
- at least two spatial axes and the angle of rotation must be numerically controlled.
- the three-dimensionally curved extruded profile can no longer be placed on an outlet table, but must be supported in the room by two or more handling robots in such a way that undesired deformation of the still soft extruded profile is avoided.
- Two exemplary embodiments of the production chain proposed according to the invention are described below.
- FIG. 1 shows a block diagram of a production chain for an AI structural component
- Fig. 2 shows a block diagram of a manufacturing chain for a Mg structural component.
- an extrusion press 1 is followed by one or more guide robots 2, which are controlled by means of a path controller 4.
- the guide robots 2 have guide devices, e.g. in the form of roller cages which guide or support the extruded profile extruded from the extruder 1 and - in the case of a rounded profile - deform with a constant or variable curvature in one plane or in space.
- guide devices e.g. in the form of roller cages which guide or support the extruded profile extruded from the extruder 1 and - in the case of a rounded profile - deform with a constant or variable curvature in one plane or in space.
- up to three handling robots 3 may be required, which grasp the profile, support it, and finally on one, without exerting any deformation forces pass on the subsequent cutting robot 5, which is provided with a cutting tool, for example in the form of a circular saw, which cuts the extrusion profile during a brief interruption of the extrusion process.
- a cutting tool for example in the form of a circular saw, which cuts the extrusion profile during a brief interruption of the extrusion process.
- a flying saw that cuts the extrusion profile without interrupting the extrusion process, by moving it together with the separating robot to which it is attached, with the extrusion profile.
- a plurality of moving handling robots 3 are required, which are controlled in such a way that they can be returned to a starting position when an end position is reached, so that preferably two handling robots 3 always attack the extrusion profile, while a third handling robot 3 is implemented.
- the separated extrusion profile is taken over by a handling robot 3, which either either directly processes the hot-forming process 8 or upstream of it.
- th cooling zone 9 supplies Fig. 1).
- the finished molded structural component is in turn subjected to the process step of heat curing 10 via handling robots 3 or another transport device before it is fed to a downstream processing center, for example by means of further handling robots 3.
- AI structural component according to FIG. 1 is to be connected to further Mg modules, this is done either by gluing 7 before the heat curing 10 or in a welding and processing center 11 for friction stir welding of Al-Mg modules. Another machining operation can take place in a conventional machining center 12. Only then can the finished structural component be delivered to the dispatch 13.
- the cooling zone 9 shown in dashed lines in FIG. 1 is only required for special materials in which abrupt cooling before the hot-forming process 8 is unavoidable, as is the case, for example, with hardenable wrought aluminum alloys (Al-Mg-Si alloys). With these alloys, it is important to avoid hardening by Mg 2 Si precipitates in a temperature range from 520 ° to 200 ° C.
- the inert gas atmosphere comprises all manufacturing steps vo exit from the extrusion press 1 to the entrance to the hot forming process 8.
- a cooling zone 9 can be connected to the hot forming process 8, which serves to accelerate the process sequence, i.e. enables a faster feeding of the extruded profile to the subsequent curing in the heating furnace 10.
- Such a cooling zone 9 is of course also conceivable in connection with the process control according to FIG. 1.
- the component can be connected to other components or modules by gluing 7 before the thermosetting 10.
