Abstract

A processing system and method for processing a cast raw casting has a spray system for cooling the raw casting. The spray system has at least one nozzle device for at least temporally, locally, or quantitatively variable application of a free-flowing medium to at least one section of the raw casting. The processing system also has a temperature measuring device for measuring the temperature on at least one section of the raw casting and a monitoring device for controlling and adjusting the nozzle device as a function of the measured temperature.

First claim

What is claimed is:

1. A processing apparatus for processing a cast raw casting, the processing apparatus comprising:
a spraying apparatus for cooling the raw casting, said spraying apparatus having at least one nozzle device for temporally, spatially, or quantitatively variable application of a flowable medium to at least one section of the raw casting;
a temperature measurement device for measurement of temperature at at least one section of the raw casting; and
a control device operatively configured to control and regulate the at least one nozzle device as a function of measured temperature;
wherein the processing apparatus is configured to coarsely deburr and finely deburr the raw casting during a single processing step.

2. The processing apparatus according to claim 1 , further comprising:
a geometry measurement device for measurement of at least one geometry of the raw casting.

3. The processing apparatus according to claim 2 , further comprising:
a comparison device that: (i) compares a value of the measured temperature with a reference temperature value, and/or (ii) compares a value of the measured geometry with a reference geometry value.

4. The processing apparatus according to claim 1 , wherein
the at least one nozzle device has at least one two-substance nozzle for application of two mutually different flowable substances to the raw casting, and
by way of the two-substance nozzle, the two mutually different flowable substances are combinable in a quantitatively variable fashion to form the flowable medium.

5. The processing apparatus according to claim 1 , wherein the spraying apparatus has a plurality of nozzle devices arranged statically or movably relative to the raw casting to be cooled, the plurality of nozzle devices being arranged spaced apart from one another within the spraying apparatus.

6. A casting cell for producing a cast component, the casting cell comprising:
a casting machine having at least, one cavity for generating a raw casting; and
a processing apparatus for processing the raw casting, the processing apparatus comprising:
a spraying apparatus for cooling the raw casting, said spraying apparatus having at least one nozzle device for temporally, spatially, or quantitatively variable application of a flowable medium to at least one section of the raw casting;
a temperature measurement device for measurement of temperature at at least one section of the raw casting; and
a control device operatively configured to control and regulate the at least one nozzle device as a function of measured temperature;

wherein the casting cell is configured to coarsely deburr and finely deburr the raw casting during a single processing step.

7. The casting cell according to claim 6 , wherein the processing apparatus further comprises:
a geometry measurement device for measurement of at least one geometry of the raw casting.

8. The casting cell according to claim 6 , wherein the processing apparatus further comprises:
a comparison device that: (i) compares a value of the measured temperature with a reference temperature value, and/or (ii) compares a value of the measured geometry with a reference geometry value.

9. The casting cell according to claim 6 , wherein
the at least one nozzle device has at least one two-substance nozzle for application of two mutually different flowable substances to the raw casting, and
by way of the two-substance nozzle, the two mutually different flowable substances are combinable in a quantitatively variable fashion to form the flowable medium.

10. The casting cell according to claim 6 , wherein the spraying apparatus has a plurality of nozzle devices arranged statically or movably relative to the raw casting to be cooled, the plurality of nozzle devices being arranged spaced apart from one another within the spraying apparatus.

11. A method for producing a cast component, the method comprising the acts of:
casting a raw casting, via a casting machine, within at least, one cavity of the casting machine;
measuring a temperature of at least one section of the cast raw casting via a temperature measurement device; and
processing the cast raw casting by way of a flowable medium applied to the cast raw casting by a processing apparatus;
wherein the raw casting is subjected to coarse deburring and fine deburring during a single processing step.

12. The method according to claim 11 , wherein the raw casting is at least cooled or straightened via the flowable medium.

13. The method according to claim 12 , wherein:
the flowable medium is applied in a spray mist form to the raw casting, and
application of the flowable medium is temporally, spatially, and/or quantitatively controlled via a control device.

14. The method according to claim 11 , wherein at least one geometry of the raw casting is measured via a geometry measurement device.

15. The method according to claim 14 , wherein:
a value of the temperature measured by the temperature measurement device is compared, via a comparison device, with a reference temperature value, and/or
a value of the at least one geometry measured by the geometry measurement device is compared with a reference geometry value.

16. The method according to claim 11 , wherein the cast component is produced within one casting cell having:
a casting machine having at least one cavity for generating a raw casting; and
a processing apparatus for processing the raw casting, the processing apparatus comprising:
a spraying apparatus for cooling the raw casting, said spraying apparatus having at least one nozzle device for temporally, spatially, or quantitatively variable application of a flowable medium to at least one section of the raw casting;
a temperature measurement device for measurement of temperature at at least one section of the raw casting; and
a control device operatively configured to control and regulate the at least one nozzle device as a function of measured temperature.

17. The method according to claim 11 , wherein the act of processing the cast raw casting makes use of the processing apparatus comprising:
a spraying apparatus for cooling the raw casting, said spraying apparatus having at least one nozzle device for temporally, spatially, or quantitatively variable application of a flowable medium to at least one section of the raw casting;
a temperature measurement device for measurement of temperature at at least; one section of the raw casting; and
a control device operatively configured to control and regulate the at least one nozzle device as a function of measured temperature.
