Abstract

PURPOSE:To simplify the setting of a stock and to prevent the wall thickness of a product from being biased by arranging a die and an inner punch to the upper die and an outer punch to the lower die. CONSTITUTION:When a cup-shaped stock W is mounted with its opening end upward on the end surface of the outer punch 10 and the upper die 1 is lowered, the bottom wall of the stock W is put between the inner punch 6 and the outer punch 10. Under such a state the inner punch 6 is lifted against a spring 5a and the stock W is pushed from the opening end side into the orifice part 3a of the die 3. In this case, the material of the stock W is drawn inward by the orifice part 3a, pushed out by a compression from the bottom to the top to perform extrusion forming and to form the inner teeth after the forming tooth form 6a of the outer circumference of the inner punch 6 on the inner circumference of the stock W. Thereafter, with the elevation of the upper die 1 the die 3 and the inner punch 6 are elevated to the knockout pin 8 and the product is released from the die, while the bottom wall of the product is pushed by the knockout pin 8 to the end surface of the outer punch 10.
