| 摘要 | High speed cutters are attached adjacent the outlet of a wire cage making machine to sever individual cages as they issue from the machine. Upon actuation, a positioning piston swings the jaws of each cutter into a cutting position around each longitudinal cage wire and simultaneously opens a control spool to admit hydraulic fluid to a power cutting piston to sever the wire. The pistons and jaws then quickly retract to avoid interference with the advancing wires of the next cage. A hoist neutralizes the weight of the cut cage while the wrap wires are cut, and a second hoist automatically transports and deposits the cage at a preselected location. | ||||||
| 权利要求 | 1. Wire cutting apparatus for use on a machine for making wire cages for reinforcement of concrete structures, comprising: a. a support frame, b. opposed wire cutter jaws, c. means on said frame mounting said jaws for movement into and out of a cutting position adjacent said frame, d. means connected to said frame for moving said jaws into and out of said cutting position, and e. means connected to said frame for operating said jaws to cut a wire therebetween when said jaws are in said cutting position. 2. Wire cutting apparatus as defined in claim 1 comprising means actuated by said jaw moving means after predetermined movement of said jaws toward said cutting position for effecting operation of said jaw operating means. 3. Wire cutting apparatus as defined in claim 1 wherein said means for moving said jaws into and out of said cutting position comprises a piston having valve spool means connected thereto and operated thereby, said spool means also being connected to said jaw operating means for causing operation of said jaws after predetermined movement of said jaws toward said cutting position. 4. Wire cutting apparatus as defined in claim 1 wherein said jaws are mounted about a common pivot for cutting movement toward one another, and wherein said jaw operating means comprises a power piston and inclined surface means on said piston and said jaws to move each said jaw toward the other upon actuation of said power piston. 5. Wire cutting apparatus as defined in claim 4 wherein said jaws are pivoted into and out of said cutting position about said common pivot. 6. Wire cutting apparatus as defined in claim 1 wherein at least a portion of said jaw operating means operates in a direction at least somewhat parallel to the usual direction of movement of the cage wire to be cut, to reduce the dimensions of said cutter normal to the wire path. 7. Wire cutting apparatus as defined in claim 1 further comprising a hoist assembly to support a wire cage adjacent the cage making apparatus during operation of said cutting apparatus to sever the cage wire. 8. Wire cutting apparatus as defined in claim 7 further comprising a self-propelled hoist and controls therefor for carrying a severed cage to a predetermined location, depositing the cage, and returning for another cage. 9. Wire cutting apparatus for use on a machine for making wire cages for reinforcement of concrete structures, comprising: a. a support frame, b. opposed scissors action wire cutter jaws mounted about a common pivot for cutting movement toward one another, c. a power piston operably connected to said wire cutter jaws to move each said jaw toward one another upon actuation of said power piston, d. means on said frame mounting said jaws about said common pivot for movement into and out of a cutting position adjacent said frame, e. positioning piston means connected to said frame for moving said jaws into and out of said cutting position, and f. valve spool means connected to and operated by said jaw positioning piston means, said spool means also being connected to said jaw power piston for actuating said power piston to operate said jaws after predetermined movement of said jaWs toward said cutting position. 10. Wire cutting apparatus as defined in claim 9 further comprising: a. a hoist assembly to support a wire cage adjacent the cage making apparatus during operation of said cutting apparatus to sever the cage wire, and b. a self-propelled hoist and controls therefor for carrying a severed cage to a predetermined location, depositing the cage, and returning for another cage. |
