METHOD OF MANUFACTURING RAIL LASHES AND COMPLEX FOR IMPLEMENTING METHOD Russian patent published in 2019 - IPC E01B11/46 E01B31/18 B23K31/02 B23K101/26 C21D9/04 

FIELD: rail vehicles.

SUBSTANCE: method of manufacturing and heat treating rail lashes comprises the manufacture of a rail lash, including successively butt-welding of rails, removing burrs and grinding the contour of welded joints. Then the editing of welded joints and quality control of welded joints is carried out. Heat treatment of a rail scourge includes the differentiated heating of elements of a rail scourge profile and their differential cooling. Heat treatment begins after the manufacture of the entire rail whip is completed, that is simultaneous manufacturing and heat treatment operations on a single rail scourge are excluded. Complex for the manufacture and heat treatment of rail lashes includes successively located welding unit, reamer, grinding unit for the contour of welded joints, straightening unit for the welded joints and quality control unit for the welded joints. Heat treatment unit for a fully made rail scourge is located independently of the components and assemblies for the rail scourge manufacturing and is made with the possibility of differentiated heating and cooling of the rail scurf profile elements in each of its cross sections. Means of moving the rail lash through the heat treatment unit are independent.

EFFECT: invention can be used for the manufacture of welded rail lashes and subsequent heat treatment thereof.
