Method and device for applying compressive and/or tractional forces to essentially rod-shaped workpieces consisting of electroconductive and/or magnetisable material

本发明涉及一种用于将压缩力和/或牵引力施加到基本上为杆状的工件上的方法，依照该方法能够避免在杆状工件(1)中的机械接触。为此，本方法涉及将压缩力和/或牵引力施加到由导电和/或可磁化材料制成的基本上为杆状的工件上。在力的施加方向上具有梯度的磁场被施加到工件(1)上。本发明也涉及一种用于将压缩力和/或牵引力施加到由导电和/或可磁化材料制成的基本上为杆状的工件(1)上的装置。所述装置包括线圈装置(5)，该线圈装置中流有电流，并被设计为用于产生具有梯度的磁场。 The disclosure relates to a method for applying compressive and/or tractional forces to an essentially rod-shaped workpiece, according to which a mechnical engagement in the rod-shaped workpiece can be avoided. To this end, the method involves applying compressive and/or tractional forces to an essentially rod-shaped workpiece including an electroconductive and/or magnetizable material. A magnetic field is applied to the workpiece, including a gradient in the direction of the force to be applied. The disclosure also relates to a device for applying compressive and/or tractional forces to an essentially rod-shaped workpiece including electroconductive and/or magnetizable material. The device includes a coil arrangement that is supplied by a current and is designed to produce a magnetic field having a gradient.
