RÖHM
Two-jaw bar pullar chucks - GF
Type 546-00 Two bar puller chucks GF for cylindrical shank DIN 69880
Chucks without shank, without jaws
APPLICATION RANGE
These bar puller chucks are mainly used for moving and positioning bars and tubes.
To grip the work, the bar puller chuck is moved against the chucked round stock, usually by means of the toolholder provided on the machine. The 30° approach angle chamfer causes the jaws to be positively forced outward until the workpiece diameter is reached and the work is gripped on the outside diameter.
The gripping force is produced by a floating cup spring assembly acting on the jaws. The workholding chuck opens to release the round stock which has been gripped by the bar puller and moved into the predeterminated position. In this position, the work is chucked again by the workholding chuck while the bar puller is simply pulled off.
The jaws are automatically pushed inward by the the cup spring assembly to return them to their initial position. The interchangeable cylindrical shank meets DIN 69880.
TECHNICAL FEATURES
When the chuck is open, the top jaws have a slight inward inclination.
In this position, the serrations must be so positioned (with respect to the workpiece) that the distance between the gripping surfaces of the jaws is 2-3 mm smaller than the workpiece.
