Abstract
The invention relates to a method for creating elevations (21) in a workpiece (1) by forming techniques. In a first step, depressions (11, 12) are created, with dimensions that differ from dimensions of depressions (20) to be created between the elevations (21). In a second step, the elevations (21) are created from regions (13) between the depressions (11, 12). The invention also relates to an apparatus for implementing the method and to a product thereby created.
Claims20
A method for forming elevations in a workpiece, comprising the steps of:
- in a first step, producing a plurality of depressions in the workpiece using a tool, wherein the plurality of depressions include first depressions and second depressions, and wherein the first depressions have dimensions which differ from dimensions of the second depressions, and
- in a second step, producing elevations from regions of the workpiece between the first depressions and the second depressions.
An apparatus for forming elevations in a workpiece, comprising:
- a first tool including a first cavity configured to accommodate the workpiece, and first teeth projecting into the first cavity and radially positioned about a longitudinal axis of the first tool;
- and
- a second tool including a second cavity configured to accommodate the workpiece, and second teeth projecting into the second cavity and radially positioned about a longitudinal axis of the second tool;
- wherein:
- end regions of the first teeth of the first tool are at different spacings from the longitudinal axis of the first tool,
- at least two of the first teeth of the first tool have different dimensions, and
- the second teeth of the second tool have the same dimensions.
A method for forming elevations in a workpiece, comprising the steps of:
- in a first step, producing a plurality of depressions in the workpiece using a tool, wherein the plurality of depressions include first depressions and second depressions, and wherein the first depressions have dimensions which differ from dimensions of the second depressions, and
- in a second step, producing elevations from regions of the workpiece between the first depressions and the second depressions,
- wherein dimensions of the first depressions have larger dimensions and are at smaller spacings from a longitudinal axis of the workpiece than the second depressions based on a configuration of the tool.
