摘要： In the metal billet to be used for hot dilation forming, a forward side with respect to the pressing direction has a quadrate section and its diagonal length is not more than an inner diameter of a container. Moreover, a backward side with respect to the pressing direction has a circular section and its diameter is substantially same as the inner diameter of the container. The metal billet is heated to a temperature suitable for press working and is set into a container for press forming. While a center of a workpiece of the metal billet is being bored by a boring punch to be operated by a pressing machine, the metal billet is hot-dilated so that a bottomed container for a cask is formed.

摘要： Double-stem type extrusion method and apparatus used for extrusion-molding rod-like and tubular products. In order to upset a solid or hollow billet (5, 5A) supplied to a container (1), the end of the container (1) which is on the side of a press stem (6) is closed with a blistering-preventing cover (11) which is not moved relatively to the container (1). A pressure is then applied to the billet (5, 5A) from the side of a die (8) to start the yield deformation thereof from the same side thereof. As the yield deformation movement of the billet (5, 5A) progresses, the air existing between the inner surface of the container and billet (5, 5A) is discharged from the portion of the container (1) which is on the side of the cover (11).

An angle is defined between the punch axis and a line tangent to the surface of the punch head at the extruding corner which is in the range of about 130.degree. to about 170.degree.. The punch and die are formed so that upon the punch reaching the end of its stroke wherein it is located within the die recess, the distance between the surface of the punch head and the first bottom surface of the die is greater than the distance between the extruding corner of the punch and the side surface of the die.

摘要： A method for warm forging a cup-shaped piece is disclosed. In warm forging a blank is heated between 400.degree. and 800.degree. C. and is inserted within a die having a cross sectional area substantially larger than that of the blank. The ends of the blank are clamped between a recess in the die and a recess in an upsetting punch and the upsetting punch compresses the blank until its sides become sufficiently bulged to almost touch, or touch, the sides of the die. The upsetting punch is then removed and a backward extruding punch is press fitted into the bulged blank and the blank is extruded to form a cup. The extrusion punch is lubricated and cooled by lubricant and coolant applicators at a position remote from the die so that the blank is not prematurely cooled by the coolant.
