PURPOSE:To obtain a clamp dirving device which is compact in its structure and is capable of operating at a high speed, by connecting an operating means of a clamp to a press machine, and providing it in a crown and an upright. CONSTITUTION:When a slide 5 is lifting, a material of a substance to be worked is carried into a station A through a material feed device 22, and also a product whose working has been completed is carried out from a station J. Subsequently, when the slide 5 goes down, the press work is performed in each station A-J. The substance to be worked of each station is held by a finger 24 of a lifting feed bar 23, and is sent to the next station. As for the clamp operation of said finger 24, a rotating motion of a clamp cam formed in one body with a rotary shaft which is not shown in the figure is transferred to an up-and-down motion of a connecting rod for clamping, also both gears 69 are operated through an L-lever and a clamp connecting rod 68, by which a pantagraph mechanism 70 is operated and the finger 24 is operated. |
