この発明はピストンロッドなどのように、一端又はその
両端にフランジを備えた軸材の鍛造(こ使用されるアプ
セツタ一式横型プレスの金型に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a die for a horizontal press with an upsetter set used for forging a shaft member having a flange at one or both ends, such as a piston rod.

ジ部分のメタルフローが悉く切断されるところから材料
強度の面からも種々の問題が見られたものである。For example, when forging a large member with a flange at the shaft end, such as a piston rod for ships, conventionally, a steel material with a diameter matching the flange diameter was prepared, the whole was scorched, and one end was stamped with the desired flange thickness. - Because the cutting method is used, in which a notch is made leaving 1111111 and the shaft is extended to a predetermined diameter, an excessive amount of heat is required to heat the entire steel material. In addition, this method leaves a large amount of excess material on each part, which not only reduces machining costs and work efficiency, such as increasing the amount of cutting during finishing and complicating centering work, but also reduces the cost of the flange part. Since the metal flow was completely cut off, various problems were observed from the viewpoint of material strength.
一方、上述したような従来のせぎり鍛造の欠点を解消す

レーム1を摺動自在に設けてなるものである。On the other hand, in order to eliminate the drawbacks of the conventional segi forging as described above, the applicant had previously developed a horizontal press and had already received a patent (Patent No. 1075173). To explain the outline of Figure 1,
1 is a bed frame; 2 is a fixed frame installed in the middle of the bed frame 1;
A half-split anvil 3 and a die 4 can be attached to the fixed frame, while a crosshead 6 with a push anvil 5 is mounted on one side of the fixed frame, and a movable frame that receives the end of the round steel A on the other side. 1 is slidably provided.
尚、図中8はクロスヘッド6を介して押金敷5を押動す

したものである。In the figure, 8 is a cylinder frame that pushes the push anvil 5 through the crosshead 6, and 9 is a rotating device for the push anvil, which is capable of rotating by a fixed angle per one stroke of the push anvil. .

メタルフローが切断されて、軸強度を低下させるという
問題点が残されていたものである。First, in the above-mentioned horizontal press device, one end of the round steel A with the desired shaft diameter was scorched in advance, and the waist was attached to the anvil 3 of the fixed frame.
While protruding from the surface, its end is fixed horizontally by the movable frame 1, and it is upset between the push anvil 5, the anvil 3, and the die 4, thereby solving the various problems seen in conventional segi forging. This is a major solution to the
Even with this device, since the presser foot 5 has been flat and the mouth edge of the die 4 has been at right angles, it is possible to forge a piston rod having the shape shown in the dotted line in Figure 2, for example. In particular, there was still a large amount of excess material (shaded area in Figure 2) on the outer circumference of the flange, the flange base opening that required a certain curvature machining, and the stepped portion of the flange surface (shaded area in Figure 2), and the amount of cutting was large. In addition, there remained the problem that the metal flow in the above-mentioned portions A, B, and C was cut, reducing the shaft strength.
このような実情に鑑み、本件発明者は、更に研究、改善

続したメタルフローを得ることに成功したものである。In view of these circumstances, the inventor of the present invention has conducted further research and improvement, and for forging a large piston rod having the shape shown in FIG. By using a push anvil equipped with a protrusion and a die with a desired curvature surface formed on the rim of the die, it is possible to obtain die forging that is extremely close to the final shape of the desired shaft member.
As a result, we were able to significantly reduce the amount of finishing cuts and achieve continuous metal flow.

可能としたものである。The structure will be described in more detail below based on the embodiment shown in FIGS. 3 and 4. The half-split anvils 3, 3 fitted to the fixed frame 2 described above have a desired inner diameter when they are combined. A half-split die 4, 4 whose mouth edge has a curved surface configuration corresponding to the curvature (r) of the flange base is located at a position approximately matching the outer diameter of the flange F and set back from the end face by a distance corresponding to the flange thickness. is fitted inside, and a ring 10 is further fitted from the outside of the fixed anvil 3 to fix these members together.

With the scorching end of the round steel A protruding a certain length, it is pressed with the anvil 3, die 4 and ring 10, the other end is horizontally supported and fixed by the movable frame 1, and then the cylinder 8 and the rotating Activating the push anvil 5 by the device 9 and upsetting the flange F portion is the same as in the conventional horizontal forging, but the end of the round steel is moved by the action of the push anvil 5 to the fixed anvil 3 and the die 4. A predetermined flange F is forged and molded along the inner surface.

Since the upsetting pressure is sufficiently increased, the effect on the inside of the steel anvil is extremely good, and a forged product close to the final shape can be easily obtained.

。As described above, according to the present invention, by upsetting while regulating the external shape with a fixed anvil and at the same time providing a constant curvature surface (1) at the die mouth, the forged product is in the finishing stage. Not only does it significantly reduce the amount of cutting on each side of the flange, making the work more efficient, but it also improves the shaft strength by minimizing the cutting of the metal flow in each of the above parts. This brings about a remarkable effect in forging large shaft members having this type of flange.
