Abstract

The invention discloses a rotary rail part assisting feeding device for high-speed turnout steel rail hot forging forming. The device is composed of a long limb hoisting rotating clamp and a short limb hoisting rotating clamp; the outer periphery of the long limb hoisting rotating clamp and the outer periphery of the short limb hoisting rotating clamp are in semi-arc shapes. The interior of the long limb hoisting rotating clamp is of a long limb side profile modeling profile of a rail part, and the interior of the short limb hoisting rotating clamp is of a short limb side profile modeling profile of the rail part; the two end sides of diameter parts of semicircles of the long limb hoisting rotating clamp and the short limb hoisting rotating clamp are provided with fastening bolt blocks respectively; and the long limb hoisting rotating clamp and the short limb hoisting rotating clamp are of hub-shaped structures respectively, and the long limb hoisting rotating clamp and the short limb hoisting rotating clamp are provided with rope groove installation portions.

Description

Technical field [0001] The invention belongs to the technical field of hot forging forming of steel rails, and specifically relates to a rail auxiliary feeding device for hot forging forming of steel rails. Background technique [0002] Since 2005, various domestic and foreign turnout manufacturers have carried out the transformation of the automatic rail feeding system in the AT rail heel end forging process. The system automatically clamps, moves up and down, moves left and right, and rotates within a 180° range. The rail parts are automatically released, horizontally moved and positioned, longitudinally positioned, drafted, reset, and blanked. However, due to factors such as high investment and development costs, limited company sites, and shorter rails in the original turnout design, the system is designed to meet the longest rail length of only 25 meters. [0003] In the railway industry, “high-speed railway turnouts” are commonly called “high-speed turnouts”. High-speed turn...
