Knuckle punching from Shear-Form Machine Tools

The 2 by 20 ton servo electric punching power is transferred to the ram through a knuckle system for a softer punching action and programmable stroke. This produces a high punching rate at reduced energy costs to alternative machine configurations, it is claimed. The machine, available from Dimeco Alipresse's sole UK representative Shear-Form Machine Tools, is controlled by a Dimeco SIMOSTAR NC control managing up to 11 programmable servo axis, features x and y positioning axis, 200 kN high speed press drive systems with programmable bottom and upper dead points, 52 standard cartridge tools selection system fitted in 4 exchangeable cassettes, which if required can be replaced by auto-index or multi-tool programmable rotating dies. This all electric punching machine is designed for coil strip up to 34 in wide using one side tool holder and up to 68 in using 2 side tool holders facing each other. Other options include a punching tonnage monitoring including automatic toll brake control and tool lubrication with oil injection through the top of the tool using programmed oil quantities.
