Abstract

The invention provides a steel rail torsion tool used for steel rail torsion and a steel rail manufacturing device, and relates to the technical field of steel rail manufacturing techniques. The steelrail torsion tool comprises a first torsion block, a second torsion block and a base, wherein the first torsion block is provided with a first through hole penetrating through the first torsion blockin the thickness direction, the first through hole comprises a first rail head hole, a first rail web hole and a first rail bottom hole, the first rail head hole is located in the top end of the first rail web hole, the first rail bottom hole is located in the bottom end of the first rail web hole, and the first rail head hole, the first rail web hole and the first rail bottom hole separately penetrate through a rail head, a rail web and a rail bottom of a steel rail; the second torsion block is provided with a second through hole penetrating through the second torsion block in the thicknessdirection, the second through hole comprises a second rail head hole, a second rail web hole and a second rail bottom hole, the second rail head hole is located in the top end of the second rail web hole, and the second rail bottom hole is located in the bottom end of the second rail web hole; and the first torsion block and the second torsion block are symmetrically arranged on the base in the length direction of the base.

Description

technical field [0001] The invention relates to the technical field of rail manufacturing, in particular to a rail torsion tool and a rail manufacturing device used for rail torsion. Background technique [0002] Steel rails are the main components of railway tracks. Its function is to guide the wheels of the rolling stock to move forward. When the rails are working, they need to bear the huge pressure of the wheels and transmit them to the sleepers. The rails must provide the wheels with a continuous, smooth and least drag rolling surface. In the electrified railway or automatic blocking section, the rail can also be used as a track circuit. [0003] The type of rail is expressed in kilograms per meter of rail mass. There are 75kg / m, 60kg / m, 50kg / m, 43kg / m and 38kg / m rails used in my country's railways. The section shape of the rail adopts the I-shaped section with the best bending resistance, which consists of three parts: the rail head, the rail waist and the rail bot...
