Abstract

PURPOSE:To make possible the clear soan of feed bars to be quickly, surely changed correspondingly to the size of the work, by installing a specified length changer between the push-pull rod for moving the feed bars mutually near and apart, and the actuating cam mechanism for this push-pull rod. CONSTITUTION:The work B, while being pressed, is clamped or released by or from the clampers 36a, 36b and is advanced or elevated. Hereby, the cam 39 swings in the direction C, the swing lever 43 swings in the arrowed direction, and the rack rod 35 moves in the arrowed direction. As a result, the push-lull rods 16, 15 respectively moves oppositely to the left and the right, and the feed bars 32a, 32b are brought mutually near or away. The length changer 55 is installed between the link member 49 of this swing lever 43 and the rack rod 35. This length changer 55 connects the outer shell 56, provided with the through hole 57 and being connected to the member 49, to the rod 35 with the slidable inner shaft 58. Plural stopping through holes 59 of the inner shaft are matched to the through hole 57, and the stopper pin 60 is inserted or withdrawn by the device 62. The length of slide motion of the inner shaft is detected by the detector 72.
