_..',--------.......""""""=~-------------------------------- INCLINABLE -..r~=--------------------------------------------------- . - ~' AI R COUNTERBALANCES Air counterbalances are standard equipment on C-75 and C-l10 presses. They are also available, and are recommended, for use with heavy dies and long strokes, as an optional feature on C-22 thru C-60 presses. WHAT ARE AIR COUNTERBALANCES Air counterbal,mces are devices that support the weight of slide, connection, and upper die sO that it is not suspended from the crankshaft bearings. ny geared press with long stroke (regardless of size), and any press with flanged slide for large, heavy die, can benefit significantly from air counterbalancing. HOW THEY WORK Air counter alances on Bliss C-series I nclinables consist of one or t\(\lO framllmounted air cylinders with pistons connected lJy ro $ to the 3lide. Air pressure is adjustab'le to support the combined weight of the slidfl, connection, and various s:i~e die. The effect of counterbalancing Ihe ciprocat;ng mass is t.o put all clearanC€s on the "up" s de- of the ilSSem Jly. WHY COUNTERBALANCES ARE USED Counterbalancing the slide prevents ~dden shlfting of clearanoe-s. when the slide contacts the work. Weight is take off the mai be rings and the slide runs more freely. Beilriri1J wear i signific311l1y reduced and gear performance is improved, since til", t.(l!lth of the gear f.loat when tM weigh of the sHde is removed from the drive train.

o TIONAL QUIPMENT r- -----. "r -'.' ---- I A portable, ratchet-type inclining mechanism can be furnished for press sizes C-22 thru C-60 as an optional feature. This device is arranged so that it can be easily operated by hand from the side of the press. The unit is portable and can serve several presses of the same size. The inherent versatility of Bliss "C" I nclinables can be greatly extended by adding "UCO"-type die cushions to geared models. They supply blankholder pressure for drawing and forming operations and can act as bottom knockouts or lift-out pads. Every geared Bliss Inclinable now in service can be equipped with a Bliss cushion without modification. Selected specifications on pages 26·29 include Cushion model numbers for each press from 45 to 110 tons. 19
