1 DRFT Heavy duty - adjustable force nitrogen gas spring stripper Direct mounting to standard retainers for ball-lock and ISO headed punches new

2 1 1 DRFT Ball-lock punch ISO 800 headed punch 1 Bronze aluminum blank holder and stripping head Stripping force identified with colored ring 5 Ball-lock punch 7 ISO 800 punch S.H.C.S ground shoulder bolt 4 M6 charging port 6 Triangle precision retainer for ball-lock punch 8 Triangle precision retainer for ISO 800 punch Features: - Mounts directly to standard retainers - uided bronze stripping head that is removable and machinable - nti - rotation head with 8 mm stroke - 7 models from 10 mm punch diameter to 40 mm - Stripping force as high as 4100 dan - 9,000 lbs - djustable stripping force - Linkable to other NITRO STRI units for versatility - Compact design

3 Example of nitrogen stripper unit linked system DRFT Features - unique design for easy linked mounting - M6 side port connecting hole - ideal combination with Micro hoses and connection style - see nitrogen cylinders catalog of Special Springs Benefits - Same pressure in all units - djustable forces - Easy control of stripping force through control panel - Higher safety through over pressure rupture plug on the control panel. Example of 17 units mounted on aerial cams for a multi piercing of automotive door

The machining of the long stripper head, over 10 mm, always reduces the nominal stroke. Final users are required always to machine the bronze aluminum stripper head when needed before installation. Maximum stroke length must always be calculated from the first point of contact on the piercing area. The NITRO STRI unit is either available with basic stripper head (no punch point, shape built-in) or with punch point built-in. See examples how to order. lways secure the NITRO STRI on the punch retainer using thread lock (Loctite 4) and tightening torque 4 Nm.
