Abstract

A radial press is provided including a base, a hollow ring die mounted on the base rotatably relative to a press axis with an inner contour tapering in the direction of the axis and rotationally symmetrical, and a rolling element unit rotatable relative to the axis and having a pressure ring, which surrounds the axis, and a plurality of rolling elements arranged around the axis which are rotationally symmetrical. The rolling elements are supported on the pressure ring at a variable distance from the axis and can roll on the inner contour of the ring die. A rotary drive acts on the ring die or the rolling element unit and effects rotation about the axis. A feed drive also acts on the rolling element unit or the ring die and effects axial displacement of the rolling element unit and the ring die relative to each other.

Dependent claims

A radial press, comprising

a base (2),
a hollow annular die (8) mounted rotatably thereon relative to a press axis (X) and having an inner contour (10) that tapers in the direction of the press axis (X) and is rotationally symmetrical relative to the press axis (X) and
a rolling-element unit (9) capable of rotating relative to the press axis (X) and having a thrust ring (11) surrounding the press axis (X) and a plurality of rotationally symmetric rolling elements (12), which are disposed around the press axis (X) and taper at least in regions, which are rotatably axially braced on the thrust ring (11) with variable distance to the press axis (X), and which can roll along the inner contour (10) of the annular die (8),
wherein a rotary drive acts on the annular die (8) and/or on the rolling-element unit (9), causing their rotation around the press axis (X), and wherein furthermore a feed drive acts on the rolling-element unit (9) and/or on the annular die (8), causing axial adjustment of the rolling-element unit (9) and of the annular die (8) relative to one another along the press axis.
