Definitions

  • the invention relates to a device for hardening rails, in particular profiled rails, optionally with respectively different cross-sectional shape and a length of greater than 50m by cooling at least part of the respective rail cross-section over the entire rail length in a coolant, consisting of Querverschiebeschn in the area a roller table, of directing means and manipulation gripper for moving the rail in the device, at least one positioning means, each with a basin or trough with coolant and a cooling bed.
  • a coolant consisting of Querverschiebeschn in the area a roller table
  • Rails of carbon-containing, optionally low-alloy steels which are placed on a cooling bed after rolling and allowed to cool, have a pearlitic structure throughout, the material having corresponding mechanical properties.
  • the microstructure can be adjusted in such a way that at least the claimed rail head high hardness, high abrasion resistance and a has low Rissinitiation, ie, that the rail in the track has improved performance characteristics.
  • a device for hardening rails by a targeted formation of the microstructure during the cooling of the same can be designed for a passage through a spray cooling device or for a dip in a coolant.
  • Continuous spray cooling systems for rail hardening are generally simple in construction, but have the disadvantage of a large footprint, require a complex technology and can not exclude unwanted hingeschwankungen the rails in a production process not efficient. Furthermore, a precise tuning of the cooling to changing cross-sectional profiles such as tongue, groove, Vignol rails and the like. Not often done in a continuous sprayer to the extent necessary, with also possibly a delay in the cooling of cross-sectional areas in the flow to unevendeffenbeetzschschschitch and thus leads to hardness variations of the material over the rail length.
  • the invention seeks to remedy the deficiencies and sets itself the goal of creating a device of the type mentioned for the hardening of rails, especially profiled rails, with which high throughput with high reliability high quality rails can be produced economically.
  • a system according to the objective of a manipulation gripper for an unimpeded rapid movement of the expiring from the rollers rails, which allows axial alignment thereof, and a dimensionally accurate Einbringiana in a positioning and / or depositing on a transfer agent and / or on a Cooling bed accomplished exhibit.
  • the goal is achieved in a generic device, when the manipulation gripper is formed from pliers having gripping arms, which are each formed with centering parts for an axial alignment of the head of the rail and with gripping parts for cross-aligned holding the rail foot and thus a dimensionally accurate introduction of Rail in the positioning and a determination of the same is possible in this.
  • the pliers are at the same time rotatable in the same direction about a common axis at least with an angular amount to align rails from different roller positions, eg from a reclining position on the head side, hold cross-section aligned and accurately by axial rotation to be able to bring into a positioning.
  • the rail In the course of the discharge of the rail from the positioning means can be stored by rotation of the pliers, the rail with advantage in a desired cross-sectional position on a transfer agent and / or on a cooling bed.
  • the pliers are each formed with a similarly movable or engageable gripping arm.
  • the manipulation gripper and the associated transfer means can be moved transversely with more than the greatest rail height over the roller table and only the gripping arms of the pliers can be lowered vertically between the rollers of the roller table for receiving the rail, loading of the roller table end area from the rollers remains leaking rails undisturbed with respect to a simultaneous placement of rails in the hardening device, which ensures high flexibility and performance of the same or a high throughput.
  • FIG. 1 is shown in cross section an embodiment of the invention.
  • a rail 1 is spent after the stitch in the last rolling caliber (not shown) on a roller table 2 and positioned by a transverse pushing means 21 on this.
  • FIG. 1 illustrated inventive manipulator gripper 3 is designed such that this a track 1 in a lying position on the roller table 2 of this by means of a plurality of pliers 30 on the rail length correctly picks up and aligned by holding the gripping arms 31,31 'axially.
  • the pliers 30 are vertically, horizontally and rotationally movable, so that a laterally located rail from the roller table 2, axially directed, in a suspended position with a horizontal foot surface together by machine-trained parts with simultaneous clamping of the centering parts 312.312 'perpendicular to the rail axis rotated, in a positioning means 4, as in Fig. 3 shown on facilities 41,41 'can be introduced.
  • a rail 1,1 'from the roller table 2 or by a positioning means 4 can be received and stored on a cooling bed 6 or on a transfer means 61.
  • An inventive positioning means 4 is in Fig. 3 shown and has over the length of a rail 1 holding components 40, 40 'with systems 41,41', in which the rail 1 is inserted axially directed. Clamping elements 42, 42 'can be adjusted in the direction of the systems 41, 41' towards the flange ends of a rail foot 11. Positioning means 4 and 5 basin with coolant 50 cooperate during the hardening process of rails 1.
  • FIG. 1 shows in the illustrated device at least two basins 5 with coolant 50 axparallel arranged side by side, each of which is usable for curing a rail 1 part of the coolant 50 in the basin 5 has a depth which is greater than the maximum rail height to a full immersion allow the same in the cooling liquid 50.
  • coolant inlet 54 anddeschellenk Rheinen 53 are arranged on the bottom side in the basin 5, wherein to smooth out the flow velocity of the coolant 50 during flow of a rail 1 over the entire length of the basin 5 through-flow plates 51 and / or nozzle plates 52 are used for diving down.
  • Positioning means 4 for rails 1 and 5 with refrigerant tank 50, as previously mentioned, together and by means of control means (not shown) are relatively movable and at least in the positions "diving of cross-sectional parts" and / or “head hardening” and / or “full Dip hardening "can be positioned for periods.
  • a groove rail 1R in comparison with a Vignolschiene 1V in Fig. 4 can Ax deviations A Z , A R between Kopfaxe x and preparedaxe y be given.
