Abstract
1. Способ изготовления деталей типа «вал с фланцем» путем торцевой раскатки, включающий установку нагретой заготовки в матрицу с проходным отверстием под вал детали, и последующее формирование фланца заготовки пуансоном, установленным под углом к оси матрицы, отличающийся тем, что используют цилиндрическую заготовку постоянного диаметра, при этом в заготовке предварительно выполняют продольную проточку с образованием опорной поверхности в виде радиального уступа и возможностью размещения проточенной части заготовки в отверстии матрицы.2. Способ по п.1, отличающийся тем, что в качестве заготовки используют сортовой прокат с сечением в виде круга.3. Способ по п.1, отличающийся тем, что в качестве заготовки используют толстостенную трубу.4. Способ по п.1, отличающийся тем, что радиальный уступ опорной поверхности заготовки выполняют величиной, не менее 0,07 от диаметра проходного отверстия в матрице.5. Способ по п.1, отличающийся тем, что радиальную величину продольной проточки заготовки выполняют с обеспечением теплового зазора между ней и проходным отверстием в матрице.6. Способ по п.1, отличающийся тем, что используют заготовку, длина которой определяется длиной самого вала с учетом массы сминаемой части и удлинения заготовки при раскатке.1. A method of manufacturing parts of the "shaft with a flange" type by end rolling, comprising installing a heated billet in a matrix with a bore for the shaft of the part, and the subsequent formation of the billet flange with a punch installed at an angle to the axis of the matrix, characterized in that they use a cylindrical billet of constant diameter, while in the preform, a longitudinal groove is preliminarily performed with the formation of a supporting surface in the form of a radial ledge and the possibility of placing the machined part of the preform in the hole of the mat tsy.2. The method according to claim 1, characterized in that high-quality rolled products with a cross section in the form of a circle are used as billets. The method according to claim 1, characterized in that a thick-walled pipe is used as a preform. The method according to claim 1, characterized in that the radial ledge of the supporting surface of the workpiece is performed with a value of not less than 0.07 from the diameter of the through hole in the matrix. The method according to claim 1, characterized in that the radial value of the longitudinal groove of the workpiece is performed to provide a thermal gap between it and the passage hole in the matrix. The method according to claim 1, characterized in that a workpiece is used, the length of which is determined by the length of the shaft itself, taking into account the mass of the crushed part and the elongation of the workpiece during rolling.
