Abstract
A continuous processing machine for bending long metal rods includes a rod bundle handling machine for separating a bundle of rods and advancing the rods one after the other, a rod cutting station and a rod bending station provided downstream of the handling machine for cutting and subsequently bending the rods. Transfer means are provided for transferring the rods from station to station.
Claims34
A continuous processing machine assembly for bending long metal rods comprising:
- a rod bundle-handling unit comprising a frame having a front side and a rear side,
- an elongated support extending outwardly at said front side of said frame for supporting a bundle of rods at the middle portion of the rods with said rods extending transversely to the direction of extension of said support, said support having a rear end and a forward end and being mounted on the frame at the rear end of said support for reciprocation upwardly and downwardly with respect to the frame,
- means for vibrating said support;
- said support being mounted for positioning in an inclined position with respect to the frame;
- means for adjusting the inclination of said support;
- means adjustably mounted at lateral opposite sides of said frame engageable with the opposite ends of the rods for positioning the rods with respect to said support,
- means for raising and lowering said support,
- an advancing roller rotatably mounted at the forward end of said support and having grooves in the periphery thereof for advancing individually the rods from the forward end of said support,
- a cantilever arm mounted on said frame above said support extending in substantially the same direction as said support and being inclined downwardly toward the forward end of said support defining a space between said support and said cantilever arm providing a gradually restricting space for limiting the number of rods moving toward said advancing roller and a restricted space adjacent said advancing roller for the passage therethrough of single rods,
- power means for adjustably positioning said cantilever arm in said inclined position, and
- sliding bars disposed downstream of said advancing roller outwardly therefrom for receiving said rods from said advancing roller and supporting the rods for sliding movement of the rods forwardly;
- cutting means disposed downstream of said sliding bars for cutting the rods;
- feeding means for feeding the rods from said rod bundle-handling unit to said cutting means;
- bending means disposed downstream of said cutting means for bending said rods;
- means for feeding the cut rods from said cutting means to said bending means;
- and
- means for removing bent rods from said bending means.
