Definitions

  • the invention relates to elongate structural parts as safety elements for automobile body construction, known in the form of lateral impact supports, bumpers, and column reinforcements. Because of more stringent requirements, the use of high strength and highest strength steels has increased.
  • the structural parts in general, are manufactured as pressed parts from sheet metal blanks or by shaping and stamping tubes. However, they can also be produced by edge rolling/profiling of steel strip. In addition to a very high strength, such structural parts must have a minimum ductility of 5% to 10%.
  • each structural part is first shaped or configured by shaping blanks, steel strip, or tubes of hardenable steel in the soft state; is heated subsequently, in a substantially vertical position, at least regionally to the austenitizing temperature required for hardening by an induction element, surrounding the structural part and movable relative to the structural part from the bottom to the top so as to follow the contour of the structural part; and is finally cooled by a cooling unit following the induction element in the direction of movement.
  • hardenable steels for example, 22 Mn B5 mod.
  • the blanks or tubes of hardenable steel are shaped in the soft state to the desired configuration of the structural parts.
  • the structural parts can also be manufactured by edge rolling/profiling of steel strip.
  • the term blank is meant to include sheet metal blanks or pieces, tubes, and steel strips or bands.
  • the structural parts can be designed as open or closed profile members.
  • the profile cross-sections can vary between the structural parts and can be of different complexity. Furthermore, the profile cross-sections can change over the length of the structural parts.
  • the structural parts can be provided without problems with curvatures and bent portions.
  • the wall thickness of the structural parts can be extremely small. In general, the wall thickness is in the range of 1 mm to 3 mm.
  • the structural parts After configuration of the structural parts they are then hardened while being substantially vertically positioned. Heating during hardening is realized by means of an induction element that can be moved relative to the structural parts along their length, i.e., in the longitudinal direction.
  • the induction element surrounds the structural parts and the shape of the induction element is matched to the cross-section of the structural parts.
  • the induction element can be an induction coil with a single winding or several windings.
  • a plate induction element is also feasible.
  • One advantage of a plate-shaped induction element is that it provides improved efficiency and ensures a more uniform heating of the diverse cross-sections when used on complex pressed parts with varying cross-sections.
  • the induction element When the induction element is appropriately designed, it can simultaneously heat at least two adjacently positioned structural parts. For this purpose, the induction element surrounds all structural parts.
  • the induction element can be matched to each of the structural parts as needed. Furthermore, it is possible without problems to select a frequency for the induction current that is matched to the structural parts.
  • the advancing speed of the induction element and/or the power can be adjusted in order to ensure at all times a uniform heating temperature over the length of the structural part as well as across the entire cross-section.
  • the cooling of the heated structural parts is carried out with the aid of a cooling unit which follows the induction element in its direction of movement.
  • the induction element and the cooling unit can be moved upwardly relative to the position-fixated structural parts (from the bottom to the top) or, alternatively, the structural parts can be moved downwardly (from the top to the bottom) relative to the induction element and the cooling unit arranged below it.
  • the respective cooling medium comes into contact with the structural parts only after they have been heated so that heating and cooling are definitely separated from one another by a certain amount of time. Furthermore, contact of the liquid cooling medium with the induction element is prevented, and the risk of voltage flashover is eliminated.
  • the induction element and the cooling unit are guided along the contour of the structural part such that the two device components are positioned at all times substantially perpendicularly to the center axis of the cross-section of the structural part. This ensures a heating and cooling action as uniform as possible even for complex, spatially curved structural parts.
  • the inventive method provides substantial cost savings in regard to the device to be used as well as to the energy consumption. Furthermore, another advantage is the minimization of the hardening distortion of the structural part.
  • a directed adjustment of crash or failure behavior of the structural parts can be achieved.
  • the non-hardened regions of the structural parts then form the constructively desired folding and crumple (collapsible) zones which enhance the predefined deformation of the structural parts.
  • a directed local adjustment of the strength values with regard to the component load can be provided, e.g., in analogy to the so-called tailored blanks comprised of different steel quality.
  • any type of welding seam is eliminated when employing inductive hardening as suggested with the method of the invention.
  • wide transitional strength zones can be realized, and an abrupt strength jump is thus prevented.
  • the hardening distortion which cannot be prevented during hardening, can however be reduced by a suitable fixation of the structural parts during hardening.
  • the degrees of freedom of the securing means accordingly can directly influence the distortion behavior.
  • already during shaping of the structural parts from blanks or tubes or by edge rolling of steel strip it is possible to take into account later hardening distortions by providing a respectively adjusted shape. An improved dimensional precision of the structural parts will result.
  • the securing means can be of a flexible design for accommodating various configurations.
  • the induction element and the cooling unit can be position-adjusted relative to one another.
  • the adjustability of the spacing between the induction element and the cooling unit can be used to affect the cooling rate and thus the hardness or strength of the structural parts.
  • the cooling unit can be a divided into several cooling elements in the circumferential direction of the structural part in order to thus influence more precisely the hardening distortion.
  • the induction element is operated at high frequency.
  • frequencies of 400 kHz to 800 kHz are especially advantageous.
  • complex, thin-walled structural parts can be heated substantially uniformly over the entire cross-section.
  • the induced eddy current in the structural parts is substantially uniformly distributed over the cross-section.
  • each structural part is subjected to a liquid stream in the area of the cooling unit.
  • the cooling liquid can be, e.g., water, oil or an oil/water mixture.
  • Another possibility of subjecting the structural parts to a cooling medium is to provide a liquid mist that is sprayed onto the structural part in the area of the cooling unit. Such a liquid mist is finely atomized. This produces a gentler cooling in comparison to the abrupt cooling action of a liquid. It is also possible to realize an incomplete cooling of the structural parts, i.e., a certain residual heat is retained in the structural part which then results in self-tempering of the structural part.
  • each structural part in the area of the cooling unit may be a gaseous medium.
  • the gaseous medium may be air or compressed air or an inert gas.
  • An inert gas prevents at the same time scale formation at the structural part. In this manner a possibly required scale removal, for example, by sand blasting, can be eliminated. Also, possible decarburization of the material of the structural part can be prevented.
  • a gaseous cooling medium or a liquid mist in combination with a liquid for cooling of the heated structural part. Accordingly, a slow cooling action by a gas stream or a liquid mist and a subsequent quenching with a liquid can be performed.
  • the cooling units with the different cooling media are arranged at a different spacing below the induction element. In this way, a defined course of the cooling curve within the time-temperature-conversion diagram is possible.
  • each structural part can be partially hardened as desired according to specific requirements.

  • the structural part 1 , 1 ′ is surrounded according to the representations of FIGS. 1 and 3 by an induction element 12 having a cross-section that is substantially matched to the structural part 1 , 1 ′.
