Description
жени одного относительно другого в вертиксшьно поперечных плоскост х заготовка подвергаетс скручиванию. Причем скручивание со стороны передней и задней частей заготовки происходит в противоположных направлени х до тех пор, пока существуют выступы . Дальнейшее обжатие заготовки приводит к образованию новых выступов . В результате скручивани в теле заготовки действуют дополнительные по сравнению с эффектом воздейст ВИЯ известного инструмента сдвиговые деформации, которые интенсифицируют деформирование литой структуры металла и способствуют завариванию внутре них дефектов.bridging one against the other in the vertical transverse planes of the workpiece is twisted. Moreover, the twisting from the front and rear parts of the workpiece occurs in opposite directions as long as the projections exist. Further compression of the workpiece leads to the formation of new projections. As a result of twisting in the body of the workpiece, additional shear deformations, as compared with the effect of the known tool, intensify the deformation of the cast metal structure and contribute to the brewing of internal defects.
Режим ковки на предлагаемом инст .рументе дл ковки валов должен быть следующим: чередование обжатий и подач с кантонками после каждого прохода . При этом подача заготовки равна величине смещени между вырезами, обжатие - удвоенной глубине вырезов. Предлагаемый ин)струмент дл ковки валов ПО сравнению с базовым объе том, в качестве которого прин т прототип , noBHiaaeT качество вгшов за. .счет интенсификации деформировани The mode of forging on the proposed tool for forging shafts should be as follows: alternation of reductions and feeds with cantones after each pass. In this case, the feed of the workpiece is equal to the amount of displacement between the notches, the reduction is twice the depth of the notches. The proposed Institute for the forging of rolls comparing with the base volume, which was taken as a prototype, noBHiaaeT quality of tires for. by intensifying deformation
литой структуры металла и создани более благопри тных условий заваривани внутренних дефектов.the cast metal structure and the creation of more favorable conditions for brewing internal defects.
