The disclosure relates to wrench devices and more particularly pertains to a new wrench device for tightening or loosening fasteners in a cutting die. The device includes a tool which includes a handle, a shaft and a magnet disposed on the shaft. The magnet has a magnetic strength that is sufficient to break free of a fastener once the fastener has been approximately hand tightened. In this way a fastener in a cutting die can be tightened or loosened in a fastener well of the cutting die.
The prior art relates to wrench devices including an electromagnetic retrieval toll that includes an electromagnet disposed within a probe and a pistol grip. The prior art discloses a magnetic retrieval tool which includes a tube and a magnet retractably disposed in the tube. The prior art discloses a variety of telescopic retrieval tools which each at least includes a telescopic shaft and a magnet disposed on an end of the telescopic shaft.
An embodiment of the disclosure meets the needs presented above by generally comprising a cutting die that has a rubber surround and the rubber surround has a fastener well. A fastener is insertable into the fastener well in the rubber surround and the fastener includes a head. A tool is provided which has a handle, a shaft extending away from the handle and a magnet that is disposed on the shaft. The shaft is insertable into the fastener well in the rubber surround thereby facilitating the magnet to magnetically engage the fastener in the fastener well in the rubber surround. In this way the tool facilitates the user to tighten or loosen the fastener without requiring the fastener to be gripped.
An additional embodiment of the disclosure meets the needs presented above by generally comprising a method of tightening or loosening a fastener in a cutting die which includes the steps of providing a cutting die has a rubber surround which has a fastener well. The steps include providing a fastener that has a head and the fastener is insertable into the fastener well in the rubber surround. The steps include providing a tool that has a handle, a shaft extending away from the handle and a magnet that is attached to a distal end of the shaft which has a lower end. The steps include inserting the shaft into the fastener well in the rubber surround thereby facilitating the lower end of the magnet to magnetically engage the head of the fastener in the fastener well in the rubber surround. The steps include rotating the handle thereby facilitating the fastener in the fastener well in the rubber surround to be tightened or loosened.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A tool 28 is provided which has a handle 30, a shaft 32 extending away from the handle 30 and a magnet 34 that is disposed on the shaft 32. The shaft 32 is insertable into the fastener well 16 in the rubber surround 14 thereby facilitating the magnet 34 to magnetically engage the fastener 20 in the fastener well 16 in the rubber surround 14. In this way the tool 28 facilitates the user to tighten or loosen the fastener 20 without requiring the fastener 20 to be gripped. The shaft 32 is comprised of a rigid material, including but not being limited to steel or aluminum. Additionally, the magnet 34 may comprise a neodymium magnet which has a magnetic force sufficient to engage the fastener 20 to tighten the fastener 20 to a torque that is approximately equivalent to the torque an average person can apply by hand tightening the fastener 20. In this way the fastener 20 can be approximately hand tightened while still facilitating the magnet 34 to be disengaged from the fastener 20 when the fastener 20 has been approximately hand tightened. The fastener 20 may comprise a hex head bolt that is comprised of a ferromagnetic material.
The shaft 32 has a distal end 36 with respect to the handle 30 and the magnet 34 has a top end 38 and a bottom end 39. The top end 38 is attached to the distal end 36 of the handle 30 and the bottom end 39 has a well 40 extending toward the top end 38. Additionally, the well 40 in the bottom end 39 is centrally positioned on the bottom end 39. The bottom end 39 magnetically engages the top surface 24 of the head 22 of the fastener 20 in the fastener well 16 in the rubber surround 14 when the shaft 32 is inserted into the fastener well 16. In this way the tool 28 can tighten or loosen the fastener 20 in the fastener well 16 without engaging the perimeter surface 26 of the head 22 of the fastener 20 in the fastener well 16 in the rubber surround 14. The shaft 32 may have a length ranging between approximately 12.0 mm and 50.0 mm. The magnet 34 may have a length and a width ranging between approximately 12.0 mm and 24.0 mm.
In use, the handle 30 of the tool 28 is gripped and the shaft 32 is inserted into the fastener well 16 in the rubber surround 14 such that the magnet 34 magnetically engages the head 22 of the fastener 20 in the fastener well 16. In this way the fastener 20 can be loosened to remove the fastener 20 from the fastener well 16. Additionally, the magnet 34 facilitates the fastener 20 to be removed from the fastener well 16 once the fastener 20 is fully loosened. The fastener 20 can be dropped into the fastener well 16 and the shaft 32 can be inserted into the fastener well 16 such that the magnet 34 magnetically engages the head 22 of the fastener 20. Thus, the fastener 20 can be tightened for securing the cutting die 12 in place. Furthermore, the magnet 34 releases the head 22 of the fastener once the fastener 20 is tightened to a torque that is approximately equivalent to being hand tightened. In this way the fastener 20 is inhibited from being over tightened and potentially damaging the cutting die 12.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
