Definitions
- the present invention relates to a method according to the preamble of claim 1 as well as a device for carrying out such a method.
- a light-alloy wheel provided with spokes for a vehicle passes through several different processing steps or processing stations during its production process.
- the rear spoke edges i. those spoke flanks, which are not visible to a viewer in the finally purpose-mounted on the vehicle alloy wheel, are deburred or rounded.
- This above-mentioned burr then builds up in the further machining of the light metal wheel, which is a machining machining - for example by means of turning tool - extremely on - especially on the outlet side of the turning steel - and can even be referred to as a collection of material rather than burr.
- This burr or accumulation of material is highly undesirable because he or she reduces the mechanical quality of the alloy wheel and hinders significantly the paintability of the alloy wheel. Therefore, this or this at the rear
- Burr edges or have formed burr or material collection must be deburred or rounded. This is to minimize the notch effect and, in view of the subsequent painting of the spokes in the course of the manufacturing process of the light-alloy wheel, the construction of a corresponding sufficient the paint layer thickness in the edge area to avoid edge corrosion can be ensured.
- so-called brush deburring machines are used for the automated removal of said unwanted burr or said unwanted material accumulation.
- these brush deburring machines are not able to achieve the desired result reliably. You achieve - and only by a high cost of materials - a partial result, which requires manual rework in each case. Namely, the brush of the brush deburring machine of the prior art can not reach every portion of the spokes of the light metal wheel, so that in certain areas as a result of machining missing a rounding and these areas must then be treated manually with great effort.
- the invention is therefore based on the object to provide a method for rounding an unwanted burr and / or an undesirable accumulation of material at the rear edges of spokes of a light metal wheel in the process of its manufacture for a vehicle, which is more reliable than that of the prior Technically known rounding can be carried out by means of a brush deburring machine and makes the need for appropriate manual post-processing of the spokes of the light-alloy wheel dispensable or at least lowers considerably compared to the prior art.
- a further object of the invention is to provide a device for carrying out this novel method.
- the method according to the invention involves rounding off an unwanted grain and / or undesired accumulation of material at the back edges of spokes a light metal wheel for a vehicle, in particular for a motor vehicle, which is in the process of being manufactured.
- the occurrence of this undesired ridge or unwanted material accumulation and the question of why this ridge or this collection of material are undesirable have already been explained or discussed above.
- the rear edge of a spoke is that edge of the spoke of the light metal wheel which is not visible to the observer when the alloy wheel is mounted on a vehicle as intended.
- the front edge of a spoke that edge of the spoke of the light metal wheel is referred to, which is visible to the viewer when the alloy wheel is mounted on the vehicle as intended.
- the light metal wheel may be, for example, an aluminum wheel or a magnesium wheel, or the light metal wheel may consist, for example, of an aluminum-containing alloy or of a magnesium-containing alloy. But it can also be any other alloy wheel with spokes.
- the said burr or the named material accumulation is rounded by means of a laser remelting process using a laser beam generated by a laser.
- this rounding is achieved by orienting the light-metal wheel during the laser in such a way that the rear edge of the respective spoke to be lasered is directed downwards, and that by introducing energy of the laser beam, the light metal is at the abovementioned Speiche partially and directly from above, ie at a front edge of this aforementioned spoke, and / or laterally melted from above, so that the melt flowing as a result of gravity flowing down, cures on the spoke back in the form of a rounding and on this way rounds out the unwanted burr existing there or the unwanted accumulation of material existing there.
- Protective gas is preferably applied to the respective affected edge during the entire reflowing and curing in order to avoid contamination of the light metal and furthermore to ensure consistent metal quality and quality.
- Aligning the rounding to the underside of the spoke, ie to the rear edge of the spoke, is carried out in the method according to the invention only by the physically given weight, since the laser process is carried out from above and the molten metal can flow to the bottom of the spoke.
- a rigid laser is preferably used for carrying out the method according to the invention, and the light metal wheel is operated by means of a three-dimensional manipulator, for example by means of a robot with gripper. correspondingly past the stationary laser source, wherein in most embodiments of the method according to the invention the three-dimensional manipulator keeps the light metal wheel firmly clamped during this aforementioned movement.
- the light metal wheel is preferably measured three-dimensionally beforehand by means of a suitably designed measuring device, all of which
- an exemplary embodiment of the method according to the invention proceeds as follows, and very preferably completely automatically: a) gripping the light metal wheel by the three-dimensional manipulator, for example by a robot gripper,
- step d) on the basis of the measured values obtained in step c), automated calculation of the necessary laser paths along the spokes of the light metal wheel, thus the corresponding necessary trajectories of the three-dimensional manipulator, and feeding the corresponding calculation results to a control guiding device of the three-dimensional manipulator for the purpose of corresponding subsequent control of the movement of the three-dimensional manipulator with respect to the fixed laser head,
- An exemplary embodiment of a device according to the invention for carrying out the exemplary embodiment of the method according to the invention described in the preceding paragraph has the following: the stationary laser, which may be, for example, a fiber laser or a CO 2 laser, with the fixed laser head,
- the automated three-dimensional manipulator which can be for example a robot with gripper
- control device for controlling the movement of the three-dimensional manipulator
- the measuring device for the automated three-dimensional measuring of the light metal wheel in the spoke area of the light metal wheel
- a data processing device for the automated calculation of the necessary laser paths along the spokes of the light metal wheel, that is to say the corresponding necessary trajectories of the three-dimensional manipulator
- a device for supplying the corresponding calculation results of the data processing device to said control device of the three-dimensional manipulator for the purpose of corresponding subsequent control of the movement of the three-dimensional manipulator with respect to the fixed laser head the fixed laser with the fixed laser head, the automated three-dimensional manipulator, the control device for controlling the three-dimensional manipulator, the aforementioned measuring device, said data processing device and the device for supplying the calculation results of the data processing device to the control device for controlling the three-dimensional manipulator and that the embodiment of the device according to the invention described here is capable of carrying out the above-described embodiment of the method according to the invention described above.
