摘要: A progressive forming machine with die and tool units, one of said units sliding a limited distance along its axis and biased by a spring force towards the other unit, the units each having an end face with a smooth surface finish adapted to press against the smooth surface finish of the end face of the other unit, the end face area of one of the units being relatively small compared to its major cross-sectional area whereby a high contact pressure between the end faces is obtained for a given spring bias force such that extrusion/cooling oil coating a workpiece received in cavity portions is restrained from leakage from the cavity portions across said end faces during a hydrostatic trapped extrusion shaping the workpiece to a degree beyond limits of conventional cold-forming processes.

摘要: A progressive former having a bolster and a ram reciprocal towards and away from the bolster, a plurality of workstations evenly spaced across the bolster and ram including aligned tooling piece holders on the bolster and ram, cylindrical die cases in the tooling holders on the bolster and cylindrical tool cases in the tooling holders on the ram, the tooling cases at the workstations being coaxial, a sideways forming mechanism at one of said workstations, the mechanism including a cam and a cam follower radially outward of imaginary outward projections of the associated tooling cases, the cam follower being arranged to be activated by forward motion of the ram towards the bolster, the mechanism including a tool for forming the blank by applying a sideways force on the blank.

摘要: A method of improving the surface finish of a sheared end face of a cylindrical blank in a progressive forming machine comprising deforming the end face out of its original as sheared transverse plane into a first shape concentric with the axis of the blank that slightly departs from the original plane a distance that increases with proximity to the axis of the blank, thereafter deforming the end face from the first shape into a second shape in a direction opposite a direction the first shape was displaced from the original shear plane, the second shape slightly departing from a transverse plane a distance that increases with proximity to the axis of the blank.

摘要: A method and tooling for forming a cartridge case blank comprising backward extruding a tube from a length of wire stock in multiple backward extrusion steps with progressive tooling to obtain an intermediate blank that can be finish drawn without a preceding annealing step and which if otherwise not subjected to multiple backward extrusion steps, would require annealing prior to finish drawing to avoid tearing.
