Abstract (en)
[origin: CA2652329A1] The invention relates to a device for hardening of rails, in particular profiled track rails, each optionally having a different cross-sectional shape and a length of more tha n 50 meters, by cooling at least a portion of the respective rail cross section over the entire length of the rail in a coolant, comprising transverse shunting means in the area of a roller gear, straightening means and manipulation grippers for conveying the rail in the device, at least one positioning means, each with a basin and/or trough with coolant and cooling bed. To create a device with which high quality rails can be manufactured economically with a high throughput and with a great reliability, it is proposed according to the present invention that the manipulation gripper should be formed from a plurality of identically shaped aligned tongs (30) that can be operated to have the same movement, each having gripper arms (31 , 31') which are shaped with centering parts (312, 312') for an axial alignment of the head (12) of the rail and with gripper parts (311, 311') for a cross-sectionally aligned holding of th e rail base, and a precision introduction of the rail (1) into the positioning means (4) and securing of same therein are made possible and/or the positioning means (4) has a plurality of holdin g components (40) aligned horizontally with supporting rigs (41) for the base (11) of a rail ( 1) introduced in a hanging position, said base (11) being securable on the supporting rigs (41) by releasable chucking elements (42) and/or hold-down devices so that it is secured from distortion in the axial rail (1) and/or at least basins (5) are arranged horizontally at the same height side-by-side so they are axially parallel with positioning means (4), and the part of the coolant (50) that can be used for rail hardening in the basin (5) has a depth which exceeds the height of the largest rail profile by at least 10% and/or the basin (5) and the supporting rigs (41) and the releasable chucking means (42) for the base (11) of the hanging rail (1) of all the components o f the positioning means (4) can be moved in a controlled manner relative to one another vertically at the same time for introducing the rail into the coolant, and a respective vertical holding position and duration of same are adjustable.
