るおそれがあって。Problems to be Solved by the Prior Art and the Invention As shown in Japanese Patent Publication No. 48-2108, a die block of the header body has a first forging die and a space below it. A second heading die is installed with a gap between the two heading dies, and an elevating body that moves up and down with a stroke equal to the distance between the first and second heading dies is installed at the tip of a ram that reciprocates back and forth opposite the die block, Three punch holders, first to third, are fixed to the surface of the elevating body that corresponds to the die block in order from the top, with an interval equal to the interval between the first and second forging dies, and The configuration is such that the first to third punches are fitted into the respective punch holders, and the elevating body is connected to one of the rams.
During each reciprocating movement, the first and second punches are moved up and down alternately to two positions: positions corresponding to the first and second heading dies, and positions where the second and third punches are respectively corresponding to the first and second heading dies. By driving, the material supplied by the material supply device is subjected to primary forming by the first heading die and the first punch, and the primary formed product is transferred to the second heading die by the second punch, and the primary formed product is Secondary forming is performed between the second heading die and the second punch, and tertiary forming is performed on the secondary formed product between the second heading die and the third punch to produce the tertiary formed product. A device is known in which the punch is projected from a second heading die and dropped, but in such a device, an elevating body to which the first to third punches are attached in the vertical direction moves in the vertical direction. Therefore, due to space constraints, it is not possible to install a device to remove the tertiary-formed product ejected from the second heading die at high speed. Therefore, when the operating speed of Heragu is increased, the product ejected from the second heading die is crushed between the second punch, etc. and the front end face of the second heading die or die block. This may result in a defective product or damage to the equipment.

に適さなかった。There is a drawback that the operating speed cannot be increased, and in addition, in the above-mentioned device, the elevating body moves back and forth in a straight line, which occupies a large movement space, and the device requires a sliding guide to make linear movement. It was large and unsuitable for high-speed operation.

成とした。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a die block of the header body with a first forging die and a second forging die arranged side by side at a predetermined interval in the horizontal direction. A punch mounting body that rotates around the center of curvature of an arc passing through the centers of each of the first and second forging dies is attached to the tip of a ram that reciprocates back and forth opposite the die block, and the punch A first punch holder, a second punch holder, and a third punch holder are placed on a surface of the attachment body corresponding to the die block, and the two punch holders are formed on an arc that is the same distance as the radius of curvature from the center of rotation of the punch attachment body. The punch mounting body is fixed at a distance equal to the distance between the dies, and the punch mounting body is positioned such that the first and second punch holders correspond to the first and second forging dies, respectively, and the second and third punch holders correspond to the positions where the first and second punch holders correspond to the first and second forging dies. The ram is equipped with a driving mechanism that rotates alternately at two positions corresponding to the first and second heading dies, and the first heading dies are attached to the material supplied to the first punch holder by the material supply device. The first punch performs primary forming between the first punch and the die, and the second punch holder receives the primary formed product from the first heading die, and the first punch performs the primary forming between the second punch holder and the second heading die. A second punch that performs secondary forming on the product is fitted into the third punch holder, and a third punch that performs tertiary forming between the secondary forming die and the second heading die is inserted into the third punch holder. In addition, a scraping-off position S for scraping off the tertiary-formed product ejected from the second heading die from above was provided in front of the second heading die.

向上する効果を奏する。Function The two-die, three-blow type ladder of the present invention has the above-mentioned configuration, and by rotationally driving the punch mounting body, the first and second punches are moved to the positions corresponding to the first and second heading dies, respectively, and the second and second punches are moved to positions corresponding to the first and second heading dies, respectively. Since the three punches are moved to two positions corresponding to the first and second heading dies, there is no need for guides or a large movement space unlike in reciprocating linear movement, so the device is compact. Therefore, it is suitable for high-speed operation, and since the product ejected from the second die is forcibly removed by the knock-off device installed in front of the second die, it is suitable for high-speed operation of the header. The ejected product completely escapes from the second die before the ram approaches again, thus avoiding double striking and damage to the equipment thereby allowing high-speed operation of the yatsugoo. This has the effect of significantly improving product production efficiency.

により払い落される。When the punch mounting plate 25 is rotated clockwise and held at the first position shown in FIG. 3, the next material sheared by the shearing die 7 is placed in front of the first heading die 12 as shown in FIG. The material is transferred by the fingers 60 of the transfer device in the same manner as described above, and then, as the ram 15 moves forward, as shown in FIG. The held primary molded product is pushed into the forming hole 12b and subjected to primary molding, and between the second heading die 14 and the second punch 36, the second punch 36, which advances as the ram 15 advances, C is pushed into the forming hole 14b of the second heading die 14, and the tip surface of the second punch 36 comes into contact with the second heading die 14 before the ram 15 reaches the front dead center position, thereby causing contact with the second heading die 14. The gap is eliminated, and as the ram 15 advances, the second punch 36 relatively retreats within the second punch holder 32, and at the same time, the forming pin 40 further pushes the primary molded product C into the forming hole 14b, thereby forming the ejecting pin 14c. The primary molded product C is crushed between the molding pin 40 and the molding pin 40 to perform secondary molding, and then the ram 15 retreats and the punch mounting plate 25 rotates counterclockwise to the second position shown in FIG. As the ram 15 moves forward after being held at 2 heading dies 1
4 and the forming hole 41 of the second punch 43 to perform tertiary forming, and then when the ram 15 retreats, the primary formed product C in the first forging die 12 is crushed into the first forging die 12 in the same manner as described above. 2 punch 36 and the second heading die 1
4, the product e subjected to tertiary forming is projected forward by the ejection pin 14c, and the ejected product e swings downward in front of the second heading die 14.

本実施例においては、パンチ取付板２５をその回転軸２
６周りに回転駆動するようにしたから。In this embodiment, the punch mounting plate 25 is attached to its rotating shaft 2.
Because it is driven to rotate around 6.
パンチ取付板２５が移動の際に占める空間が極く小さく
、したがって装置空間が小さくなって装置が小型となり

ヘッダーを高速度で運転することが可能となる。The punch mounting plate 25 occupies an extremely small space when moving, so the device space becomes small and the device becomes compact.Furthermore, the French drawing lever 56 only needs to cross in front of the second heading die 14, so the second The product e ejected from the heading die 14 can be immediately brushed off, making it possible to operate the header at high speed.
