发明名称 Device and non-cutting shaping method for introducing an outside profile into a workpiece
摘要 A portable handheld device for introducing an external profile into a longitudinal workpiece by noncutting shaping includes a locking element and a profiling tool having a pitchless profile disposed opposite the locking element and disposable at an adjustable angle as a function of a desired lead angle of the external profile within a force transmission plane, wherein the workpiece is disposable and removable between the profiling tool and the locking element, and wherein the profile tool and the locking element are configured to execute a feed movement relative to one another and to be adjustable to a neutral position.

主权项 1. A portable handheld device for introducing an external profile into a longitudinal workpiece by noncutting shaping, the device comprising: a profiling tool in the form of a thread-rolling tool configured to form the external profile in the workpiece; and a locking element forming an angle between 35° and 160° on a side facing the profiling tool so as to be configured to lock in place on an outer diameter of the workpiece, the profiling tool being disposed in a force transmission plane opposite the locking element, having a pitchless profile, and being disposable at an adjustable tilt angle so as to be inclined relative to the workpiece as a function of a desired lead angle of the external profile, wherein the workpiece is disposable and removable between the profiling tool and the locking element when the profiling tool and locking element are in a neutral position, wherein the profiling tool and the locking element are configured to execute a feed movement relative to one another such that the neutral position is adjustable, and wherein the locking element includes a profiling configured to engage in interspaces of the introduced external profile so as to improve a transfer of force by the locking element.
