Abstract

PURPOSE:To automate the mounting and dismounting of feed bars by moving a clamp rod by way of a wedge mechanism by the cylinder secured to one of the split type feed bars of a transfer press and engaging its head part with the other feed bar. CONSTITUTION:To disconnect the connected feed bars, pressure fluid is discharged and supplied to and from openings 6b, 6a respectively, then the piston 7 in a cylinder 6 moves upward against the pressing force of a spring 8. This causes a taper block 9 to be moved upward, then a movable taper block 11 and a clamp rod 12 are pushed toward the left in the figure and the takeout side feed bar 3 having been clamped by the rod 12 is moved upward by a moving bolster or the like and is transferred to outside the press together with the dies. To connect the feed bars, on the other hand, the bar 3 descends upon touch-down of the moving bolster and the rod 12 head part fits into the groove 3a. The piston 7 is moved downward by the action of the pressure fluid reverse to the above-mentioned case and the rod 12 is pulled to the stationary feed bar 4 side, by which the bar 3 is clamped to the bar 4.
