    • In order to permit the use of bars of material to be machined without a piminary preparation of the rearward end of the bar being necessary, the pusher head presents ribs extending inwardly, and the surfaces of which directed toward the axis form cone portions. Between these ribs are free spaces where possible burrs may lodge. The ribs include shearing edges for eliminating the burrs if the burr is located on a rib, rather than in the free space. Furthermore, the angle of conicity is small. Thus, a rear bar face in rough state, not having been prepared by straightening or taper turning, does not express itself by any appreciable decentering.

    • Feed apparatus for automatic lathes comprises a central section bar surrounded by one or more peripheral section bars, longitudinal grooves of arcuate cross-section in all the section bars matching and cooperating with each other to form longitudinal passages for guiding bar stock when the section bars are assembled. Linings may be placed in these passages to form tubes for guiding the bar stock, these tubes being very accurately positioned relative to the outer surface of the apparatus, which may be an outer tube into which the assembly of section bars is inserted. Hence the stock-guiding tubes can be more precisely positioned, and the apparatus can be produced at low cost because the section bars are inexpensive and assembly is simple. The apparatus is particularly suitable for feeding lathes on which objects made from bar stock of very different diameters has to be machined.
    • 自动车床的进给装置包括一个由一个或多个周边部分条围绕的中央部分条,在所有截面条中的弓形横截面的纵向槽彼此匹配并配合,以形成纵向通道,用于当条形杆 组装 可以将衬片放置在这些通道中以形成用于引导棒料的管子,这些管子相对于设备的外表面非常准确地定位,该外部管子可以是插入组件的组件的外管。 因此,可以更精确地定位原料引导管,并且可以以低成本生产该装置,因为截面棒是便宜的并且组装简单。 该装置特别适用于进给车床,在其上必须加工有非常不同直径的棒材制成的物体。
