[0002] F-shaped steel rails are used on medium and low-speed maglev tracks. In order to ensure the installation requirements of medium and low-speed maglev tracks, it is necessary to straighten or bend the F-shaped steel rails. Therefore, the device and method for bending F-rails for maglevs is an important agricultural resource. , in the existing F rail bending device and method for magl

Abstract

The invention discloses a device and a method for bending an F rail for magnetic levitation. The device comprises a headstock (1) for supporting, an upper roller (2) arranged on the headstock (1) androtating relative to the headstock (1), a lower roller (2) rotating relative to the headstock (1) and moving relative to the upper roller (2), a right roller (4) rotating relative to the headstock (1)and moving relative to the upper roller (2) and a left roller (5) rotating relative to the headstock (1) and moving relative to the upper roller (2). The right roller (4), the lower roller (3) and the left roller (5) are distributed along an arc-shaped line. The F type steel rail is clamped through the upper roller (2) and the lower roller (3); a bending action force is generated to the F type steel rail through the right roller (4) and the left roller (5); and extending and shrinking action forces are generated to the F type steel rail through the upper roller (2), the lower roller (3), theright roller (4) and the left roller (5). The F type steel rail is no longer straightly corrected manually or bended to deform, so that peristaltic wrinkles are prevented from being generated on the side part of the F type steel rail, and therefore, the deformation quality of the F type steel rail is improved.

Description

technical field [0001] The invention relates to a device and method for bending F rails for magnetic suspension, in particular to a device and method for bending F rails for magnetic suspension. Background technique [0002] F-shaped steel rails are used on medium and low-speed maglev tracks. In order to ensure the installation requirements of medium and low-speed maglev tracks, it is necessary to straighten or bend the F-shaped steel rails. Therefore, the device and method for bending F-rails for maglevs is an important agricultural resource. , in the existing F rail bending device and method for maglev, there is no device and method for F rail bending for maglev, and artificial straight line correction or bending deformation is carried out, because artificial straight line correction or bending deformation can only When the bending deformation force is applied, creep wrinkles will be produced on the side of the F-shaped rail, which affects the deformation quality of the F-...
