    摘要: A squeezing caster comprises a bed which carries a bottom plate, an intermediate carrier member, and two dies. The intermediate carrier member is of the split type. Each of the dies is mounted on a crosspiece and provided with a mechanism which drives it along the intermediate carrier member. The crosspiece is rigidly attached to said mechanism accommodated in a housing which is mounted on the intermediate carrier member. The die driving mechanism comprises a rack and four pushers. On the external surface of each pusher there is a buttress thread meshed with an internal thread of a gear whose outer teeth are meshed with the rack. One of the racks is intended for connection to a rod of a drive cylinder and provided with a link which is kinematically coupled to the other rack. The caster also contains a means for a preliminary advance of one of the dies.
