Abstract

PURPOSE: Not only to grip the work without damaging it but also to give it tensile force.
CONSTITUTION: Two wedges 8, 9 are fitted to the rod 7 by inserting them into the inclined T-groove 12 provided on the tip of the piston rod 4. And, the rod 7 is moved to the right, the wedges 8, 9 are moved to the right along the T-groove 12, the work 10 is inserted between them by leaving a mutual space, and after that, pressure oil is fed from the feed and discharge port 14, it is discharged from the feed and discharge port 15, the wedges 8, 9 are moved to the left along the T- groove 12 by the rod 7, and the work 10 is pressed from the upper and lower sides by generating the wedge grip action between the piston rod 4 and the wedges. Subsequently, pressure oil is fed from the feed and discharge port 16, it is discharged from the feed and discharge port 17, the piston rod 4 is moved to the right, and tensile force is put on the work 10. In this way, the wedges 8, 9 are moved only in the direction meeting at right angles to the work 10, and therefore the work 10 is not damaged.
