MACHINE FOR PRODUCTION OF CUTTING-DRAWING SCREEN OF SHEET MATERIAL Russian patent published in 2015 - IPC B21D31/02 B21D35/00 B21D47/02 

FIELD: process engineering.

SUBSTANCE: invention relates to forge-and-press equipment, particularly to machine for stamping grates from sheets. Moving knife beam with cut-out blade is articulated with machine eccentric shaft. Note here that said beam is provided with straps and jaws arranged on beam both sides to displace in contact. Note also that said jaws have lubricant feed holes to contact with straps. Besides, fixed beam with fixed knife includes position adjustment mechanisms arranged at edges. Kinematic linkage of moving knife beam is composed of the first main kinematic link. The latter makes said moving knife beam with cut-out blade to swing relative to swing axis. Second auxiliary kinematic link drives the moving knife beam with cut-out blade in crosswise direction. Third kinematic link is composed of sheet stepwise feed mechanism.

EFFECT: enhanced performances, higher quality.
