Definitions

  • a device for forming workpieces by means of magnetic pulse forming is specified. Furthermore, a method for forming workpieces, in particular a magnetic forming method for forming body sheet metal parts, is specified.
  • Magnetic forming is an electrodynamic high-energy forming process for cold forming of flat and cylindrical semi-finished products made of electrically conductive materials using pulsed magnetic fields.
  • the workpiece positioned near the coil is formed by the force of a pulsed magnetic field of very high intensity without contact, i.e. without mechanical contact with a tool on the side facing the magnet. As a result, neither surface contamination nor tool marks occur.
  • the magnetic forming process is based on the physical fact that a time-varying magnetic field induces eddy currents in neighboring electrically conductive bodies.
  • the strength of the induced currents and thus the force acting on the workpiece depend crucially on the electrical conductivity of the material used.
  • the magnetic field exerts forces on these currents, the strength of which depends on the spatial gradient of the magnetic flux density and the magnitude of the induced currents, so that the conductive body to be formed experiences a force in the opposite direction to the direction of the coil. This force only acts for a few microseconds while the capacitors are discharging.
  • the workpiece absorbs the required forming energy in the form of an impulse, which accelerates it and reaches speeds of up to 300 m/s.
  • the occurring in the workpiece Stresses so high that flow occurs in the sense of forming technology and the shape of the tool underneath the workpiece is adopted.
  • Magnetic fields suitable for magnet forming are generated, for example, by discharging charged capacitors in the course of a few tens of microseconds via a coil adapted to the workpiece geometry, which creates a very high magnetic field pulse in the area of the workpiece surface. The magnetic forces cause the coil to expand and the workpiece to move toward lower fields.
  • a flat, spiral-shaped coil is usually arranged parallel to a flat sheet metal workpiece which lies on a forming tool or die underneath. If the magnetic field is generated directly above the material, it is pressed into the recesses of the forming tool or die by the electromagnetic forces. The magnetic field acts like a conventional press stamp.
  • the pulsed magnetic field can be dosed very precisely, which means that metals can be pressed onto glass, plastics, composites or metals with high repeat accuracy. Magnetic fields and magnetic forces work unhindered through materials such as glass, ceramics and plastic, which is why magnet forming can also be used under vacuum, in an inert gas atmosphere or under clean room conditions. Forming in a liquid is also possible (e.g. water).
  • the magnetic impulse is transmitted through the fluid in the form of a wave.
  • high-strength steel and aluminum alloys can be cold formed in almost any way without cracks occurring in the material.
  • forming is the generic term for all manufacturing processes in which metals or thermoplastics are plastically shaped in a targeted manner.
  • a primary material is formed into a semi-finished product or workpieces are produced from the semi-finished product.
  • the material retains its mass and cohesion during the forming.
  • Forming differs from deformation in that the change in shape is introduced in a targeted manner. Deformation, on the other hand, is an untargeted plastic change in shape.
  • Forming lines that are currently known in the state of the art have a large number of presses and deep-drawing systems in which high-strength and high-strength steels are cold, semi-hot or hot formed. For this purpose, the material is partly heated in the press or deep-drawing system and then formed. One forming is usually carried out per station, so that the workpieces are transported between the individual stations by hand or fully automatically.
  • Forming in several steps can have various reasons, one of which is the limited formability of the material per work step.
  • Sometimes components are reheated between the forming steps in order to reduce the stresses in the material introduced during the forming. This has a high energy consumption as well as a longer one result in process time.
  • a lot of energy is required for forming and for heating the material.
  • the forming lines currently used often have high plant costs and, especially in the hot forming process, high energy consumption, among other things because the hot forming process requires heating of the metal sheets for forming. Further limitations are given by limited degrees of deformation in metal forming due to long forming times.
  • a device for forming workpieces, having a magnetic forming device which comprises a forming tool and a magnetic tool, the magnetic forming device being designed to form a workpiece in a magnetic forming process.
  • a method for forming a workpiece comprising the steps of providing a device for forming workpieces, providing a workpiece, forming the workpiece by means of a magnetic forming device in a forming process.
