Self-Adjusting Bar Puller
December 1, 2013
The EZ-PULLER from Accudyne Corporation is a self-adjusting bar puller used in CNC turning centers to provide automatic operation of the machine. The design of the EZ-PULLER allows the programmer or set-up person to change bar sizes in the machine without having to manually adjust the tool.
The tool functions by means of polyurethane springs that provide force to pivoting arms. These arms in turn apply force to circular grippers at the end of the arms. The grippers rotate only under extreme load and have a serration geometry that is said to generate minimal stock penetration while providing maximum grip for a more accurate pull.
To set the tool for gripping and pulling bar stock, the tool is moved in the Z-axis until the grippers are at least .180" past the end of the stock, then moved in the X-axis until the grippers are on centerline with the material being pulled. A standard pull cycle is then initiated. The EZ-PULLER can accommodate the following bar stock sizes:
- Round stock .125" to 1.625"
- Hexagonal stock .125" to 1.375"
- Square stock .125" to 1.000".
