Claims (1)

Способ восстановления опорных поверхностей несущих деталей грузовых вагонов, включающий размещение на опорной поверхности детали накладки из износостойкой стали, нагретой до температуры ковки, и осаживание ее равномерно распределенной статической нагрузкой до толщины, равной отклонению положения опорной поверхности от номинального размера в направлении приложения нагрузки, охлаждение накладки ниже температуры Аr1 с выдержкой при максимальной нагрузке, разгрузку детали и приварку накладки к детали, отличающийся тем, что нагретую до температуры ковки накладку размещают с напуском за контур опорной поверхности и осуществляют при температуре выше Аr1 одновременно с осаживанием загиб выступающих краев накладки к боковым стенкам детали, примыкающим к опорной поверхности, при этом величину напусков накладки принимают с учетом удаления сварных швов к ненагруженным при эксплуатации зонам, равного не менее 1/2 толщины стенки, расположенной у опорной поверхности, после чего разгружают деталь и проводят приварку к ней кромок накладки по линии сопряжения со стенками детали.The method of restoring the bearing surfaces of the load-bearing parts of freight cars, including placing on the bearing surface of a part of a lining made of wear-resistant steel heated to forging temperature and depositing it with a uniformly distributed static load to a thickness equal to the deviation of the position of the supporting surface from the nominal size in the direction of load application, cooling the lining below the temperature Ar 1 with holding at maximum load, unloading the part and welding the plate to the part, characterized in that it is heated to forging temperatures, the overlay is placed with an inlet over the contour of the supporting surface and is carried out at a temperature above Ar 1 simultaneously with the bending of the protruding edges of the overlay to the side walls of the part adjacent to the supporting surface, while the overlap overlays are taken into account taking into account the removal of welds to areas not loaded during operation equal to at least 1/2 of the wall thickness located at the supporting surface, after which the part is unloaded and the edges of the lining are welded to it along the line of interface with the part walls.
