- the cast component is to be manufactured and in particular machined within a casting cell.
- the inventive processing device for processing a cast Gußrohteils has a spray device for cooling the Gussrohteils having at least one nozzle means for at least temporally, locally or quantitatively variable application of a flowable medium on at least a portion of Gussrohteils, as well as a temperature measuring device for measuring the Temperature at least a portion of Gussrohteils and a control device for controlling and regulating the nozzle device depending on the measured temperature.
- the Gussrohteil itself is advantageously a blank, which arises after the casting process, but still processed in the following and in particular must be straightened and deburred, so that from this Gussrohteil a cast component can arise, which is understood according to the present invention as a finished component, which for example, in a component group can be arranged.
- the processing device itself advantageously serves to process the casting raw part cast by means of in particular a casting machine in the following.
- the processing device has a spraying device which has at least one nozzle device which serves to apply a flowable medium, which is advantageously a water-air mixture, to at least portions of the cast raw part.
- the nozzle device of the spraying device itself can be arranged, for example, statically, that means immovable, or movable relative to the casting blank to be cooled.
- statically that means immovable, or movable relative to the casting blank to be cooled.
- the casting blank is moved along a processing or transport path through the spray device along the nozzle device or past this.
- the cast raw part is moved not only in translational movement in the direction of the transport path along the nozzle device, but also rotationally about the longitudinal axis along the nozzle device, so that there is the possibility that by means of the nozzle device on any portion of the Gussrohteils the flowable medium can be applied.
- the nozzle device In the event that the nozzle device itself is arranged to be movable relative to the casting raw part to be cooled, the nozzle device can be moved along the casting blank, which is advantageously arranged statically and therefore immovably within the spraying device, in order to enable the flowable medium to be applied to any section of the casting blank , Which amount of flowable medium is to be applied in which mixing ratio in which time period and on which portion of the casting blank is advantageously determined on the basis of the measured values of the temperature measuring device.
- a control device that communicates with the temperature measuring device and advantageously with the nozzle device advantageously serves to at least control or regulate the nozzle device as a function of the measured temperature. Consequently, the control device may define how much amount of flowable medium is to be applied to the soft section of the casting blank in which time period and / or in what mixing ratio.
- the processing device serves on the one hand for cooling the Gußrohteils and on the other advantageous also for straightening Gussrohteils, as described in more detail below.
- the casting raw part is cooled by means of the processing device according to the invention due to the precisely metered flowable medium to a temperature of advantageously less than 80 ° C and more preferably less than 50 ° C, so that in the subsequent step, the coarse and fine trimming in a single Processing step can be advantageously made possible within a casting cell.
- the processing device according to the invention advantageously has a geometry measuring device for measuring at least one geometry of the casting blank.
- the geometry measuring device is advantageously a unit of the processing device and is also connected to the control device in a data-communicating manner in a wired or wireless manner in order to forward determined or measured measured values to the control device, which then determines whether a deviation of the geometry and in particular of individual dimensions of the cast raw part is present.
- control device can advantageously control the at least one nozzle device based not only on the measured values of the temperature measuring device but also based on the measured values of the geometry measuring device in such a way that they apply a defined amount of free-flowing medium to a defined section or region at defined time intervals the Gussrohteils, advantageously in a defined mixing ratio, applies to cool the Gussrohteil specifically and therefore due to a targeted Flow of Gussrohteils by means of the flowable medium targeted counteract possible distortion occurring.
- the processing device has a comparison device for comparing the measured temperature value with a reference temperature value and / or the measured geometry value with a reference geometry value. Consequently, the comparison device, which is advantageously also a unit of the processing device, is particularly advantageously connected in a data-communicating manner to the control device and compensates the actual values obtained with desired values stored, for example, in a memory device.
- the storage device is preferably a unit of the control device, but may also be an independent unit. The adjustment of the values leads, for example, to a defined application of the flowable medium to defined sections of the cast raw part and thus to a defined cooling and / or straightening of the cast raw part or else to a cooling stop and / or directional stop.
- the nozzle device has at least one two-fluid nozzle for applying two mutually different flowable substances on the Gussrohteil, wherein by means of the two-fluid nozzle, the two flowable substances to the flowable medium are quantitatively variable combined.
- the flowable medium which is for example a water-air mixture, is flexibly variable in its mixing ratio.
- the flowable medium in the form of a spray is applied to the casting blank and in particular at least a portion of the casting blank.
- the Leidenfrost effect is the lower pronounced, the finer the water droplets are atomized.
- a physical effect is described, which includes the delayed material conversion and in particular the temporally extended change of the state of matter. Based on the Leidenfrost effect, it is therefore disadvantageous possible that would extend a desired short time to cool down the Gussrohteils, for example, by an annealing between the Gussrohteil and the cooling medium steam layer.
- the amount is regulated real-time controlled, depending on the duration of spraying or the raw casting temperature.
- water accumulation on the casting raw part and, consequently, associated water carry-over within the casting cell can be prevented, in particular by the amount of sprayed water being steadily reduced, so that in particular the temporally last period of the cooling phase is advantageously carried out exclusively with air.
- the spraying device has a plurality of nozzle devices arranged statically or movably relative to the raw casting part to be cooled, which are arranged at a distance from one another within the spraying device.
- the spraying device can advantageously have two or more nozzle devices, which are advantageously controlled or regulated independently of one another by means of the control device. Accordingly, it is advantageously possible for each nozzle device of the spraying device to apply a flowable medium having a different amount to a different nozzle device of the spraying device or else a flowable medium having a different mixing ratio to each section or regions of the cast blank that are different from one another. In this way, a defined cooling of individual sections of Gussrohteils be made possible, which in turn advantageously counteracts occurring distortion by the defined cooling or by which a targeted straightening is brought about. It is also conceivable that the spraying device has a sprue gripper for positioning the casting blank relative to the nozzle device. By means of the sprue gripper, the cast raw part can advantageously be fixed within the spray device, so that the shrinkage occurring during cooling can exert no influence on the gripping position.

- the casting blank also eliminates additional manufacturing steps by within a casting cell, the cast Gußrohteil deburred after cooling and advantageously can also be addressed simultaneously, the coarse deburring and the fine deburring advantageously carried out during a processing step.
- deburring is to be understood as meaning a mechanical processing of the cast raw part, in which the casting and overflow system are removed.
- the casting machine which can also be referred to as a die-casting machine, advantageously has a mold-closing unit which serves to open and close the die-casting mold and in particular the cavity.
- the mold clamping unit itself advantageously has a fixed machine plate for receiving a fixed Eing manformhhan and a movable machine plate for receiving a hydraulic ejector.
- the movable machine plate is guided by guide columns. Closed are the fixed machine plate and the movable machine plate, for example by means of a lock cylinder.
