Bending head for bending rod- and pipe-shaped workpieces

摘要

In a bending head for bending rod-shaped and tubular workpieces, with a retainer that can be rotated about a rotational axis and that carries a bending mandrel at one axial end, and with at least two further tools, which each comprise a retaining body with, at its axial end facing the bending mandrel, a bending pin and which can each be rotated—in each case independently of the other tools—the retaining bodies of the tools are arranged concentrically to the retainer of the bending mandrel and pivotable about its rotational axis.

主权项

1. A bending head for bending rod-shaped and tubular workpieces, the bending head comprising:
a retainer with a bending mandrel at an axial end of the retainer, the retainer rotatable about a rotational axis, the bending mandrel comprising an axially extending bending pin; and a plurality of further tools, each of which comprises a retaining body with an axial end positioned at the bending mandrel axial end and a bending pin, and each of the plurality of further tools rotatable about the rotational axis and independently rotatable with respect to the retainer with the bending mandrel and with respect to each of the other plurality of tools, wherein a bending pin of one of the plurality of tools is positioned relative to the rotational axis such that the bending pin is displaced radially relative to the rotational axis and wherein the retaining body of said one of the plurality of tools is rotatably attached to an upper end wall of a housing, the retaining body is in drive connection with a first rotary drive secured to the housing, the retaining body has a lower section lying directly above the upper end wall of the housing, and the retaining body is provided with external teeth, the external teeth engaging a toothed wheel being driven by said first rotary drive, said first rotary drive being secured below the upper end wall and opposite to the toothed wheel, the toothed wheel being connected through the upper end wall to the rotary drive.
