Problems solved by technology

[0011] The forming lines used today often have high equipment investment and (especially for thermoforming processes) high energy consumption, mainly because of the need to heat the sheet during the thermoforming process in order to deform it
In metal forming, due to the long forming time, it is further limited by the limited degree of forming deformation

Embodiment Construction

[0033] In the various embodiments and drawings, components that are the same or that play the same role may be assigned the same reference numerals, respectively. In principle, the elements shown and their dimensional relationships to one another should not be considered to be true to scale. Rather, for better illustration and / or for better understanding, the dimensions of individual elements may be shown exaggerated in thickness or size.

Abstract

The invention relates to a device (100) for shaping workpieces, in particular for shaping body sheet-metal parts. The device (100) has a first magnetic forming apparatus (1), which comprises at leastone first forming tool (10) and at least one first magnetic tool (11), and a second magnetic forming apparatus (2), which comprises at least one second forming tool (20) and at least one second magnetic tool (21). The first magnetic forming apparatus (1) is designed to shape a workpiece (3) in a first magnetic forming process, and the second magnetic forming apparatus (2) is designed to further shape the workpiece (3) in a second magnetic forming process following the first magnetic forming process. The invention further relates to a method for shaping a workpiece (3).

Description

technical field [0001] The invention proposes a device for shaping workpieces by means of magnetic pulse shaping. Furthermore, the invention proposes a method for forming workpieces, in particular an electromagnetic forming method for forming body panel components. Background technique [0002] Electromagnetic forming is an electrokinetic high-energy forming method for the cold forming of flat and cylindrical semi-finished products made of electrically conductive materials with the aid of pulsed magnetic fields. The workpiece positioned near the coil is formed contactlessly, that is to say without mechanical contact with the tool (Werkzeug, die) on the side facing the magnet, by the force of a pulsed magnetic field of very high intensity processing. As a result, neither surface contamination nor tool impressions (Werkzeugabdruck, mold impressions) occur. [0003] The electromagnetic forming method is based on the physical fact that a temporally variable magnetic field ind...
