Embodiment Construction

[0021] figure 1 shows a cross-sectional profile view of an embodiment of a workpiece 2 according to the invention; as in figure 1 As shown in , the workpiece 2 may be a tubular element or a substantially cylindrical element. Among them, refer to figure 1 As shown in , the workpiece 2 can be extended down a certain distance. The invention is suitable for a somewhat more general representation of the workpiece 2 , ie the workpiece 2 is fitted in the end region in a tubular or cylindrical shape. Among them, as an example figure 1 As shown, the workpiece 2 can be free from the inside in this end region, but can of course also be filled or closed.

[0022] The workpiece 2 is formed in one piece, it is in particular not designed as an assembly of two or more separate parts, but rather consists of a single part or part. The workpiece 2 is made of only one part. The workpiece can in particular be a steel part, but of course also an aluminum part. Steel components are basically ...

Abstract

The present invention relates to an integral workpiece having a duct, and manufacturing method for same. The integral workpiece which has a duct (4) located within a region which extends, for example in an annular manner, and formed about an axis (A) of the workpiece (2). The workpiece (2) has a form-fitting connection (6) by which, when viewed in a cross section extending through the axis (A), the duct (4) is closed. The form-fitting connection (6) enables, in comparison with known manufacturing methods, particularly simple manufacturing of the workpiece (2). In particular, no welding or screwing is required for closing the duct (4).

Description

technical field [0001] The invention relates to a one-piece workpiece having a tube which is arranged, for example annularly, in a region extending around the axis of the workpiece, wherein the tube is formed by shaping. The invention also relates to a method for producing such workpieces. Background technique [0002] Such workpieces with matching tubes can be produced from steel or aluminum by casting, the tubes being designed coreless. In the case of steel components, the production can alternatively be carried out by means of a forging process, wherein the tube is formed by means of hot pressing rolls. These manufacturing methods are accompanied by high costs. The production of the tubes is also more expensive than production by means of brazing, welding or gluing. Contents of the invention [0003] It is therefore the object of the present invention to provide a matchable, one-piece workpiece which can be produced particularly easily, and a method for its manufactu...
