Abstract

Pressing tools and jaws are described which include communication provisions that enable information concerning the jaws to be used with the press tool, to be transmitted to the tool. The press tool includes provisions that limit or otherwise tailor the output of the tool based on information concerning the jaws.

First claim

What is claimed is:

1. A method of managing a system of at least one power tool and at least one tool accessory, the method comprising:
providing a controller disposed within the at least one power tool to:
count use cycles of the at least one power tool to provide a first cumulative total;
identify the at least one tool accessory attached to the at least one power tool;
count use cycles of the at least one tool accessory to provide a second cumulative total, wherein the use cycles of the at least one tool accessory are counted based on the identification of the at least one tool accessory;
compare the first cumulative total to a tool use warning value;
compare the second cumulative total to a tool accessory warning value; and
generate a warning signal when at least one of the first cumulative total is greater than the tool use warning value, and the second cumulative total is greater than the tool accessory warning value.

2. The method of claim 1 wherein the at least one power tool comprises:
interconnectivity provisions for communicating with at least one electronic mobile devices.

3. The method of claim 1 wherein the at least one power tool comprises:
interconnectivity provisions for communicating with a cloud-based server.

4. The method of claim 1 wherein the at least one power tool comprises communication provisions configured to receive information from an RFID chip to identify the at least one tool accessory.

5. The method of claim 1 wherein the at least one power tool comprises communication provisions configured to receive information from an NFC chip to identify the at least one tool accessory.

6. The method of claim 1 wherein the at least one power tool is a press tool.

7. The method of claim 1 further comprising:
storing the second cumulative total on a memory of at least one of a cloud server, a mobile device, a computer, and the at least one power tool.

8. The method of claim 3 wherein the cloud-based server stores the number of use cycles of the at least one power tool.

9. The method of claim 3 wherein the cloud-based server stores the number of use cycles of the at least one tool accessory.

10. The method of claim 6 wherein the press tool comprises:
a motor actuated by a displaceable trigger;
a hydraulic circuit including a pump, a reservoir, a hydraulic cylinder, and a piston movably disposed in the cylinder, wherein upon actuation of the motor, the pump is operated to thereby move the piston relative to the cylinder;
a displaceable ram assembly in operable engagement with the piston;
engagement provisions for releasably engaging a jaw assembly with the press tool;
communication provisions for receiving information associated with a jaw assembly to be used with the press tool.

11. The method of claim 8 wherein the cloud-based server maintains a usage history of the at least one power tool.

12. The method of claim 9 wherein the cloud-based server maintains a usage history of the at least one accessory.

13. The method of claim 10 wherein the press tool further comprises:
a magnetic switch configured to sense a position of the ram assembly.

14. The method of claim 13 wherein the press tool further comprises:
a hydraulic valve located in the hydraulic circuit of the press tool, wherein the hydraulic valve is positionable between an open stat and a closed state based upon the output state of the magnetic switch.

15. A system including a power tool and at least one tool accessory, the system comprising:
a memory disposed in the power tool;
a controller disposed in the power tool for controlling operation of the power tool, the controller configured to:
count use cycles of the power tool to provide a first cumulative total;
identify the at least one tool accessory attached to the power tool;
count use cycles of the at least one tool accessory to provide a second cumulative total, wherein the use cycles of the at least one tool accessory are counted based on the identification of the at least one tool accessory;
compare the first cumulative total with a power tool use warning threshold;
compare the second cumulative total with a tool accessory use warning threshold; and
generate a warning signal when one of the first cumulative total exceeds the power tool use warning threshold and the second cumulative total exceeds the power tool accessory use warning threshold.

16. The system of claim 15 wherein the power tool further comprises communication provisions configured to receive identification information from one of an RFID chip and an NFC chip on the at least one tool accessory.

17. The system of claim 15 wherein the power tool is a press tool.

18. The system of claim 15 wherein the at least one tool accessory includes a jaw assembly configured for use with a press tool.

19. The system of claim 17 wherein the press tool comprises:
a motor actuated by a displaceable trigger;
a hydraulic circuit including a pump, a reservoir, a hydraulic cylinder, and a piston movably disposed in the cylinder, wherein upon actuation of the motor, the pump is operated to thereby move the piston relative to the cylinder;
a displaceable ram assembly in operable engagement with the piston;
engagement provisions for releasably engaging a jaw assembly with the press tool;
communication provisions for receiving information associated with a jaw assembly to be used with the press tool.

20. The system of claim 18 wherein the jaw assembly includes:
a first jaw arm member;
a second jaw arm member;
wherein each of the first and the second jaw arm members define a front end and a rear end, and inwardly facing cam surfaces at the rear ends;
a pair of side plates between which the first and the second jaw arm members are pivotally retained; and
an electronic chip incorporated into the jaw assembly for identifying and/or providing information relating to the jaw assembly.

21. The system of claim 18 wherein the jaw assembly includes:
a first jaw arm member;
a second jaw arm member;
wherein each of the first and the second jaw arm members define a front end and a rear end, and inwardly facing cam surfaces at the rear ends;
a pair of side plates between which the first and the second jaw arm members are pivotally retained;
wherein at least one of the side plates includes a physical feature for providing information concerning the jaw assembly.

22. The system of claim 18 wherein the jaw assembly includes:
a first jaw arm member;
a second jaw arm member;
wherein each of the first and the second jaw arm members define a front end and a rear end, and inwardly facing cam surfaces at the rear ends;
wherein at least one of the first jaw arm member and the second jaw arm member includes a physical feature for providing information concerning the jaw assembly.

23. The system of claim 19 wherein the press tool further comprises:
a magnetic switch configured to sense a position of the ram assembly.

24. The system of claim 20 , wherein the chip is one of a RFID chip and an NFC chip.

25. The system of claim 21 wherein the physical feature is selected form the group consisting of a protrusion, a recess, and combinations thereof.

26. The system of claim 22 wherein the physical feature is selected from the group consisting of a boss, a protrusion, a recess, and combinations thereof.

27. The system of claim 25 wherein t
