PURPOSE:To enable two-pieces production and to improve operability by disposing die groups on both sides of a feed bar, providing fingers on the feed bar and conveying a material to be worked to the dies of the succeeding stage. CONSTITUTION:When works 6 are gripped by fingers 5 and a lifting table 19 is raised by turning a cam shaft, a feed bar 1 and the fingers 5 ascend and the works 6 are lifted. The bar 1 and the fingers 5 are moved in a direction D to feed the works 6 to above dies 32-3n, 42-4n of the next stage. The bar 1 is then lowered and the works 6 are imposed on the dies 32-3n, 42-4n. The works 6 are supplied from a supply part 9 to the dies 31, 41. A finger driving shaft 8 is moved in a direction E via links 54A, 54B to detach the fingers 5 from the works 6. Upper dies are lowered to press the works 6. The bar 1 is returned in the direction opposite from D to press sequentially the works 6 and to discharge the pressed works 6 to a receiving part 10 during this time. |
