Abstract
The disclosure relates to a cutting machine and more particularly to a cutting machine for cutting off short lengths of elongated material such as circular in cross section wire-like or tubular elements and more particularly to material commonly known as liquid silver which is small diameter tubular silver elements used to make necklaces or the like. The machine comprises a means for feeding intermittently a plurality of elongated work pieces in parallel relationship to each other and for sequencially and intermittently operating a circular saw which moves laterally relative to the work pieces and cuts off short lengths thereof. The machine comprises means for automatically sequencing the feed means and the cut-off means in timed relation to each other and such that, as for example, as many as 30,000 to 70,000 pieces may be cut in 1 hour's time.
Claims12
In a cutting machine:
- a frame;
- a material feed means adapted to feed a plurality of work pieces such as circular in cross section wire-like or tubular elements;
- said feed means having a plurality of elongated and substantially parallel material guides;
- each guide having an inlet end and an outlet end;
- an elongated feed roller having an axis of rotation disposed at substantially right angles relative to said guides;
- said feed roller having a peripheral portion provided with a plurality of annular driving grooves therein;
- said driving grooves having a depth less than the diameter of said work pieces;
- each of said driving grooves aligned with a respective one of said guides;
- a soft resilient idler roller having a peripheral portion closely adjacent said annular driving grooves of said feed roller;
- said peripheral portion of said idler roller adapted to engage said work pieces for holding them in firm engagement in said grooves of said feed roller;
- a receiver disposed to receive said work pieces from said feed roller;
- said receiver having a plurality of holes extending therethrough and adapted to receive and closely fit the exterior of said work pieces;
- intermittent drive means for intermittently rotating said feed roller a predetermined distance;
- a high speed rotary saw having a peripheral blade operable adjacent said receiver for cutting off predetermined lengths of work pieces adjacent thereto;
- said saw having an axis of rotation substantially parallel to said guide and adapted to rotate said saw in a plane at substantially right angles to said work pieces as they project from said receiver;
- means for rotating said saw at high speed;
- and actuating means for intermittently moving said saw in a direction at right angles to said guide means and said work pieces, projecting from said receiver.
