Abstract (en)

[origin: CA1144404A] The forging device is equipped with two upsettingtool holders which are shaped as angular elements. They are installed between a head and a base, are mounted slidably in a direction transverse to the head movement and are connected with the head by articulated connectors. The arms of the angular elements which are situated parallel to the head movement are equipped with upsetting tools. Between the upsetting tools a gripper of the formed material is installed, which is composed of two jaws. The arms of the angular elements, which are transverse to the head movement, are mounted slidably with regard to the jaw of the gripper in the direction transverse to the head movement. These arms are pressed against the jaw in the direction of the head movement and cause the clamping of the material between the jaws. After the material has been clamped, the jaws remain immobile during the whole metal forming process, The device permits to upset a rod or a tube simultaneously at two places or to manufacture branched forgings, like crosses, T-shapes, Y-shapes and the like.
