As of the filing date of this application, an Operator's Manual for the BH9000 backhoe is located at http://www.woodsequipment.com/manuals/manuals/Ag/38638.pdf. - Turning now to
FIG. 2 , the rebar cutter/bender utilized in the illustrated embodiment of the invention is shown broadly atreference numeral 20. The rebar cutter/bender 20 includes atop handle 21 and abottom lever 22. The top handle includes a distal portion 23 (shown in phantom) and aproximal portion 27. In order to configure the rebar cutter/bender 20 for mounting on the backhoe, thedistal portion 23 of thetop handle 21 of the rebar cutter/bender 20 is cut away and the entire bottom lever 22 (also shown in phantom) of the rebar cutter/bender 20 is removed. All components illustrated with solid lines inFIG. 2 remain to form the modified rebar cutter/bender. Among these components are acam receiver 24, amovable cutter cam 25, astationary cutter cam 26, ahandle cam 30, and acoupling cam 31. Themovable cutter cam 25 includes adistal end 43 and a proximal end 45. Thehandle cam 30, thecam receiver 24, and thecoupling cam 31 are pivotably joined together by apivot pin 32. Thecoupling cam 31 is also attached to thehandle cam 30 by afixed pin 33 that carries abolt 34. Thecoupling cam 31 also carries afirst bending post 35. Thecam receiver 24 includes abase plate 40 and anupright plate 41. Asecond bending post 42 extends from theupright plate 41. Thestationary cutter cam 26 and thedistal end 43 of themovable cutter cam 25 are pivotably joined to theupright plate 41 of thecam receiver 24 by apivot pin 44. The proximal end 45 of themovable cutter cam 25 is pivotably joined to theupright plate 41 of thecam receiver 24 by asecond pivot pin 46. Themovable cutter cam 25 and thestationary cutter cam 26 each define twonotches 47 for receiving a length of rebar “R” (FIG. 5 ). - Looking at
FIG. 3 , a backhoe utilized in the illustrated embodiment of the invention is shown broadly atreference numeral 50. Thebackhoe 50 includes abucket 51, a bucket articulation mechanism, and a hydraulic power system. The bucket articulation mechanism includes asupport arm 53, first andsecond brace bars brace bar bracket 56 centrally disposed between the first andsecond brace bars bucket 51 to the hydraulic power system of thebackhoe 50. The hydraulic power system comprises ahydraulic cylinder 57 that carries ahydraulic cylinder rod 60 that has a T-shapeddistal end 61 for engaging thebrace bar bracket 56 of the bucket articulation system. The bucket articulation mechanism has been modified by fixedly securing, for instance by welding, astop rod 62 onto thesupport arm 53 and and by fixedly securing around thefirst brace bar 54, for instance by welding, a coupler such as asupport sleeve 63. - As shown in cross-section in
FIG. 4 , the modified rebar cutter/bender 20 (FIG. 2 ) is welded to the modified bucket articulation mechanism of the backhoe 50 (FIG. 3 ) by fixedly securing, for instance by welding, thebase plate 40 of thecam receiver 24 of the rebar/cutter bender 20 to thesupport sleeve 63 that has been fixedly secured to thefirst brace bar 54 of the bucket articulation mechanism of thebackhoe 50. Thesupport sleeve 63 transmits the articulating motion of the bucket articulation mechanism to the rebar cutter/bender 20 during use of the system 10 (FIG. 1 ). As shown inFIG. 1 , thestop rod 62 on thesupport arm 53 of the bucket articulation mechanism limits the motion of theproximal portion 27 of thetop handle 21 of the modified rebar cutter/bender 20 during use of thesystem 10. - As is also shown in
FIG. 1 , a length of rebar “R” may be bent by actuating the rod cutting andbending system 10. Specifically, the rebar “R” may be threaded under thepivot pin 32 and over the first andsecond bending posts hydraulic cylinder rod 60 is retracted into thehydraulic cylinder 57, the T-shapeddistal end 61 of thehydraulic cylinder rod 60 moves thebrace bar bracket 56, which in turn moves thefirst brace bar 54 and the support sleeve 63 thereon, thereby urging the first andsecond bending posts cam receiver 24 toward thepivot pin 32 such that the rebar “R” is urged against thepivot pin 32, causing the rebar “R” to bend around thepivot pin 32. -
FIG. 5 illustrates a length of rebar “R” placed in the rod cutting and bendingsystem 10 to be cut. After thehydraulic cylinder 57 moves thehydraulic cylinder rod 60 such that thenotches 47 in themovable cutter cam 25 and thenotches 47 in thestationary cutter cam 26 are aligned, a length of rebar “R” may be placed in thenotches 47. When thehydraulic cylinder rod 60 is retracted into thehydraulic cylinder 57, themovable cutter cam 25 pivots about thepivot pin 44 while thestationary cutter cam 25 remains stationary. This movement of thenotches 47 of the movable andstationary cutter cams stationary cutter cams - Rod cutting and bending systems within the scope of the invention may also cut and bend rods of other materials and dimensions than the rebar illustrated herein. In addition, rod cutting and bending systems within the scope of the invention may utilize power sources other than hydraulic power systems and others installed on backhoes and similar earth moving equipment. The particular rebar cutter/bender and backhoe disclosed herein and the modification, assembly, and operation of those structures in the disclosed embodiment of the invention are described only to provide an example of one possible embodiment of the invention and are not provided to limit the scope of the invention. Unitary powered rod cutters and benders and powered rod cutters and benders assembled from hardware other than the specific devices described herein may fall within the scope of the invention. Furthermore, the power source for actuating the rod cutter and bender does not have to be hydraulic. It may alternatively be electric, gas-powered, or pneumatic.
- A rod cutting and bending system and method of fabricating same is described above. Various details of the invention may be changed without departing from its scope. Furthermore, the foregoing description of an embodiment of the invention are provided for the purpose of illustration only and not for the purpose of limitation—the invention being defined by the claims.
