MACHINE FOR MAKING CUT-THROUGH STRETCHED GAUZE OF SHEET MATERIAL Russian patent published in 2003 - IPC

FIELD: forging equipment, namely forming gauzes of sheet material. SUBSTANCE: machine includes frame supporting flywheel type drive mechanism, eccentric shaft joined through pair of connecting rods with beam on which cut-through cutter is mounted with possibility of reciprocation motion across direction of sheet material feed. Lower stationary cutter is mounted on table. Feeding rolls provides motion of blank at each revolution of eccentric shaft. Feeding mechanism controls angular turning of rolls; said mechanism includes support unit mounted on frame with possibility of linear adjustment motion; rocker arm whose one end is jointly secured to support unit; cam secured to cutter beam; roller mounted on rocker arm and engaging with cam; electromagnetic coupling and driven pinion both mounted on drive roll. Said driven pinion engages with driving pinion whose shaft supports freewheel clutch with casing. Casing is jointly connected with another end of rocker arm. EFFECT: possibility for continuous control of material feed, simplified adjustment of lowered-size machine, decreased metal consumption. 1 dwg
