PURPOSE:To obtain a pushing and drawing device which is excellent in capacity and durability, has a small-sized and simple structure, and is inexpensive by providing a driving band consisting of a windable band plate so as to be slidable in a guide groove, connecting a tip part of the driving band to a tool to be pushed and drawn, and constituting it so that it can be driven to move forward and backward by a driving device. CONSTITUTION:A driving band V of a pushing and drawing device is constituted of a band plate 4 of a band-shaped spring plate, etc., provided so as to be slidable in a guide groove 6 consisting of a C-shaped bar material 5 provided in a T-groove 1a provided on a bolster 1, etc. of a press machine, and a pushing and drawing output part V1 consisting of a bolt 11 and a sleeve 12 provided on a tip part 4a of the driving band V is connected to an input part M1 of a floor surface of a tool to be pushed and drawn M3. Also, a slide opening part 6a opened along the lengthwise direction is provided on the upper face of said guide groove 6, and said pushing and drawing output part V1, etc. are constituted so as to be slidable. A base part 4b of said driving band V is constituted so as to be windable and feedable in a take-up case 10 by an operation of a driving wheel 7 and driven wheels 8, 9 of a driving device D1. |
