Description
(54) СПОСОБ ПРОИЗВОДСТВА КРУПНЫХ ПОКОВОК(54) METHOD OF MANUFACTURE OF MAJOR FORGES
1one
Изобретение относитс к способам кузнечнопрессового производства.This invention relates to a forge and press manufacturing process.
Известен способ производства крупных поковок путем электрошлаковой сварки по меньшей мере двух заготовок и последуюш,ей ковки сваренного блока на окончательные размеры .A known method for the production of large forgings by electroslag welding of at least two blanks and the subsequent forging of a welded block to its final dimensions.
Однако известный способ не обеспечивает получени однородного по физико-механическим свойствам металла шва и заготовки.However, the known method does not provide a uniform in physicomechanical properties of the weld metal and the workpiece.
По предлагаемому способу ковку сваренного блока начинают с обжати сварных швов по периметру, совмеш,а плоскость шва с плоскостью симметрии деформирующей нагрузки. Это обеспечивает получение однородного по физико-механическим свойствам металла шва и заготовки.According to the proposed method, the forging of a welded block begins with a reduction of the welds along the perimeter, smeshmes, and the weld plane with the plane of symmetry of the deforming load. This ensures that the weld metal and the workpiece are uniform in the physicomechanical properties.
Способ производства крупных поковок заключаетс в том, что вначале из нескольких заготовок получают, например, с помощью электрошлаковой сварки сваренный блок. Затем блок куют на окончательные размеры.The method of producing large forgings consists in the fact that, at first, several blocks are produced, for example, by means of electroslag welding, a welded block. Then the block is forged on the final dimensions.
При этом вначале проковывают путем обжати по периметру сварные швы, совмеща плоскость шва с плоскостью симметрии приложенной деформирующей нагрузки, совпадающей обычно с осью деформирующего усили . Предлагаемый способ обеспечивает получение достаточной однородности металла сварного шва и заготовки, низкую анизотропию свойств по всей поковке.At the same time, welds are first forged by crimping along the perimeter, aligning the plane of the seam with the plane of symmetry of the applied deforming load, which usually coincides with the axis of the deforming force. The proposed method provides sufficient uniformity of the weld metal and the workpiece, low anisotropy of properties throughout the forging.
