Achieving big time and money savings at the early planning stage

Screwdriving function modules form the basis of all automated, process-reliable screwdriving
assembly operations. Visitors to the MOTEK 2011 trade exhibition in Stuttgart showed great
enthusiasm for DEPRAG’s new - thousandfold proven - generation of screwdriver units. The
pioneering modular structure of the SFMs shown promises major benefits for system
integration and plant engineers, offering advanced screwdriving technology at reasonable
terms. Reliable timescale and cost data are known right from the planning stage.

With six standard structures, there are no restrictions to covering every requirement of
modern screwdriver assembly technology. The normal version, with its slim design, is
designed to carry out horizontal screwdriving tasks, or operations from above. The short
version is particularly suited to operations where space is restricted. The under-floor version
was designed for vertical screwdriving tasks from below. The vacuum version handles tasks
in hard-to-reach or recessed screw locations in any direction. The pick and place version is
used to deal with fasteners that have a specified pick position. The nut feed version feeds
and screws nuts onto the fastenings.

The SFM-L screwdriving function module is the light and compact single spindle version for
low torques of between 2 and 80 Ncm, and is suitable for screw head diameters up to 10
mm. The SFM-N screwdriving function module - also in single spindle design - executes
screw fastenings at higher torque ranges, from 0.06 to 20 Nm, and here, screw head
diameters can range up to 14 mm. The robust SFM-S multi-spindle version is used to handle
several screwdrivers along with high pressing forces. With this module the torque range
adjusts to the specific screwdriving task in hand. Screw heads can measure up to 14 mm in
diameter. All three versions have a feed stroke of 25 mm or 80 mm as standard. Special
stroke heights are available upon request.
