Разработка схемы ковки валов с интенсивными пластическими деформациями

Разработка схемы ковки валов с интенсивными пластическими деформациями

Abstract

The schemes of forging shafts with preliminary of a profiling workpiece by wedge dies were investigated. The non-uniform of strain distribution in the transverse cross-section of the forgings was determined. The forging of the profiling workpiece by flat ensures the uniform strain distribution. The maximal value of the parameter of the stress state scheme was provided at the final forging the profiling workpiece by flat die. В работе исследованы схемы ковки валов с применением предварительного профилирования заготовки клиновыми бойками. Для этой схемы установлена неравномерность распределения деформаций по сечению поковки. Правка профилированной заготовки плоскими бойками обеспечивает равномерное распределение деформаций. Максимальное значение показателя жесткости схемы напряженного состояния обеспечивается при окончательной ковке плоскими бойками профилированной заготовки.
