ジに鍛造している。Conventional technology and its problems Conventionally, when manufacturing rear axles and other general flanged shafts for various vehicles by forging, a rod-shaped material cut to a predetermined length is used as shown in Fig. 6. After going through several steps to make it easier to form a flange by upsetting a conical shape on one end of the material and further crushing it, this is held in a grip die to form a flange with the same diameter as the flange to be formed or smaller. A punch with a large diameter is used to forge the upsetting or crushing previously formed in the previous process into a flange of the required diameter.

す。Means for Solving Problems In view of this, the present invention enables even large-diameter flange forming to be completed using a small upsetter, and involves an upsetting process at one end of a rod-shaped material cut to a required length. Either the material is then crushed, or directly from upsetting, it is held in a grip die, and a groove is formed in this grip die to match the diameter of the flange to be formed, and a punch facing the grip die is inserted from the diameter of the forming flange. It has a small diameter and is pressed into the punch insertion hole formed on the end face of the grip die, and is swung or crushed in the previous process to move the inside toward the outer circumference to obtain the desired flanged axle.
実施例 以下本発明を図示の実施例に基づいて説明する。Example The present invention will be explained below based on illustrated embodiments.

イにて挾持せしめ、まず円錐形に据込みＷｚを行なう。First, cut the rod-shaped material W1 of the desired material to a preset length C according to the product, and then cut the material at room temperature or at 800~ Forging is performed by heating to SOO°C and further heating to SOO'C or higher. Heating at 800 to 800°C is warm forging, and heating at 900°C or higher is hot forging, but regardless of whether it is warm or hot, it is only necessary to heat at least the side that will form the flange. . After the rod-shaped material is heated to a desired temperature in this manner, it is held in the grip die of the upsetter, and first, it is upset into a conical shape Wz.
これは素材径と成形フランジ径との間に大きな隔たりが
ある場合、１工程だけでなく数工程を経て行なわれる。If there is a large gap between the diameter of the material and the diameter of the formed flange, this is done not only in one step but also in several steps.
この据込み工程を経た素材を直接仕上用グリップダイに
セットすることもできるが、一般にはこの据込み工程を
経た素材をさらに潰し工程にかけフランジを成形しやす
い形状に予じめ整える。The material that has undergone this upsetting process can be directly set in a finishing grip die, but generally the material that has undergone this upsetting process is further subjected to a crushing process to pre-shape it into a shape that is easy to form into a flange.
この潰し工程を経た素材Ｗ８をグリップダイにセットす

−ど亘って二つ割となっている。The material W8 that has undergone this crushing step is set in a grip die, and the finished grip die is divided into two halves, both top and bottom and along the length of the material.
グリップダイは第２図に詳示される如く、各工

とするものである。The grip die summer shown in Fig. 2 (λ) is used when performing conical upsetting, and the rod-shaped material W1 is made to have its tip slightly protruded and other parts are clamped, and then the rod-shaped material W1 is soldered, facing this grip die. The punch 2 has a shape that allows conical upsetting. Also, the grip die 8 of TBL in the same figure
The side facing the punch is slightly recessed, and the other part is formed to hold the rod-shaped part so that it can be crushed into the desired shape, and the punch 4 facing the grip die 8 also cooperates with the punch and the grip die. It is made into the required crushed shape by action.

and a disk-shaped groove 6b forming a flange, and a punch insertion hole 5C having a diameter d smaller than the diameter of this flange,
The punch 6 facing the die 6 enters into the die through a hole 5C formed in the end face of the die 6.

である。これは素材のフランジ成形端と反対側端を自由
端とすることによって行なえる。When the punch 6 of the material W8 set in the grip die 5 for finishing is advanced toward the grip die side by driving the sputter, the punch coaxial with the grip die enters into the punch insertion hole 6c of the grip die. At this time, the conical upsetting or crushing part is inside this punch insertion hole,
By press-fitting the punch, the excess thickness of the material is pressed, which causes the groove side C to move. When the punch is press-fitted into the die to the set depth, the movement of the meat is completed and a predetermined flange is formed. At this time, the press-fitting reaction force of the punch is supported by clamping the bar-shaped part of the material at the clamping part 6 of the die, but if there is still excess material even after the groove 6b is completely filled, an excessive load will cause the die and the rod-shaped part to be supported. This prevents the die from getting caught in the upsetter and damaging the die or upsetter. In order to prevent peeling, when a die or the like is subjected to a load exceeding the maximum load set in the membrane chamber, the material held by the die is made to slide or the die is made to slide to release the excess load. This can be done by leaving the end of the material opposite the flanged end as a free end.
このようにして小型のアプセツターを用いて大径のフラ
ンジを有する製品を増進するものである。In this way, a small upsetter is used to enhance the production of products with large diameter flanges.
また異なる実権例としてはフランジ形成側のグリップダ

を一体に形成スることも可能である。Another practical example is to close the end face of the grip die on the side where the flange is formed, apply a pressing force to the material stored in the die from the side opposite to the side forming the flange, and form the flange integrally in the same way. is also possible.

存する。Effects of the Invention According to the present invention, when the required load for J-type punching is recommended to be the nominal weight of the machine, even if conventional punching is not possible, the punching area of the material by punching can be reduced, and the excess material can be removed in the outer circumferential direction. This has the advantage that even a small-sized upsetter can easily increase the fN of a large-diameter flanged axle.
