Abstract

A press die certification system for certifying a press die including a vibration severity monitor operationally connected to the press die to be certified, the monitor creating output containing vibration severity data and press run speed data. Software is utilized for creating a die certificate and die certificate data, calculated on monitor output data obtained from data memory and from press setup information.

Claims

1. A press die certification system for certifying a press die, said system comprising:

a vibration severity monitor operationally connected to the press die to be certified, said monitor creating output containing vibration severity data and press run speed data;

a data input means for entering press setup information;

a press die data memory means for saving said monitor output; and

software means for creating a die certificate and die certificate data calculated on said monitor output data obtained from data memory means and from said press setup information.

2. The system of claim 1 in which said press die data memory means is tamper resistant.

3. The system of claim 1 in which said software means outputs die certificate data to said press die data memory means.

4. The system of claim 1 in which said press die data memory means is tamper evident.

5. The system of claim 1 in which said vibration severity data and press run speed data is time stamped on its saving into said memory means.

6. The system of claim 1 in which said press setup information includes at least one of press type, stock feed material thickness, stock feed material type, die operating shutheight, and die kiss block clearance at press bottom dead center slide settings.

7. The system of claim 1 in which said data input means permits an operator to enter at least one die condition for which die certification is sought, said software determining if the die for certifying would operate at such condition and then communicating success or failure of certification at such die condition.

8. The system of claim 7 in which said vibration severity data and press run speed data is time stamped on its saving into said memory means.

9. The system of claim 7 in which said press setup information includes at least one of press type, stock feed material thickness, stock feed material type, die operating shutheight, and die kiss block clearance at press bottom dead center slide settings.

10. A press die certification method comprising the steps of:

operating a press die at various speeds and conditions and thereby creating press die performance data;

saving said created press die performance data to a memory means;

transferring said saved press die performance data to certification software;

inputting at least one of die setup and press run condition data into the certification software;

creating a press die certification document through the use of the certification software utilizing the saved press die performance data and inputted data.

11. The method of claim 10 further comprising saving the press run condition data to said memory means.

12. The method of claim 11 in which said press run condition data includes vibration severity data and press run speed data, said saving step further comprising time stamping said vibration severity data and said press run speed data on its saving into said memory means.

13. The method of claim 10 in which said saving step includes time stamping said press run condition data on its saving into said memory means.

14. The method of claim 10 in which said press run condition data includes vibration severity data and press run speed data, said saving step further comprising time stamping said vibration severity data and said press run speed data on its saving into said memory means.

15. The method of claim 10 in which said press die performance data includes selected die performance criteria measured versus press speed or selected die performance criteria versus time.

16. A press die certification system for certifying a press die, said system comprising:

a press die performance monitor operationally connected to the press die to be certified, said monitor creating output containing press die performance data and press run speed data;

data input means for entering press setup information;

a press die data memory means for saving press die performance data, press setup information and time stamp information, said data memory means accepting input from said press die performance monitor and said data input means;

software means for creating a die certification document and die certification data based on data obtained from data memory means and data input means and comparison of performance level to pre-determined acceptable/non-acceptable performance criteria levels.

17. The system of claim 16 in which said press die data memory means also saves die certification data from said software means.

18. The system of claim 16 in which said press die data memory means is tamper resistant to prevent data alteration.

19. The system of claim 16 in which said press die performance data and press run speed data is time stamped on its saving into said memory means.

20. The system of claim 16 in which said performance criteria levels include at least one of:

vibration severity zone levels, tipping moment severity zone levels, load severity levels, historical vibration severity versus time accumulation levels, and variations in press bottom dead center measurement.

21. A press certification system for certifying a press, said system comprising:

a press performance monitor operationally connected to the press to be certified, said monitor creating output containing press performance data and press run speed data;

data input means for entering press setup information;

a press data memory means for saving press performance data, press setup information and time stamp information, said data memory means accepting input from said press performance monitor and said data input means;

software means for creating a press certification document and press certification data based on data obtained from data memory means and data input means and comparison of performance level to pre-determined acceptable/non-acceptable performance criteria levels.

22. The press certification system of claim 21, wherein said press certification document is an assurance of a level of at least one of performance and usefulness of said press under a given set of use conditions.

23. A machine certification system for certifying a machine, said system comprising:

a machine performance monitor operationally connected to the machine to be certified, said monitor creating output containing machine performance data and machine run speed data;

data input means for entering machine setup information;

a machine data memory means for saving machine performance data, machine setup information and time stamp information, said data memory means accepting input from said machine performance monitor and said data input means;

software means for creating a machine certification document and machine certification data based on data obtained from data memory means and data input means and comparison of performance level to pre-determined acceptable/non-acceptable performance criteria levels.

24. The machine certification system of claim 23, wherein said machine certification document is an assurance of a level of at least one of performance and usefulness of said machine under a given set of use conditions.

25. The machine certification system of claim 23, wherein the machine certification system is configured for certifying at least one of a press, a press die, and a press machine.

26. The machine certification system of claim 23, wherein said machine data memory means is at least one of tamper proof and tamper evident.

27. The machine certification system of claim 23, wherein said performance criteria levels include at least one of:

vibration severity zone levels, tipping moment severity zone levels, load severity levels, historical vibration severity versus time accumulation levels, and variations in press bottom dead center measurement of a machine press.
