Abstract

An acoustic methodology  has been developed and expression have been obtained for determining the initial deformation rate v0 during high-speed forging of rod products. The most rational layout of the recording device relative tothe installation elements has been established while using the obtained expressions. The essence of the developed technique lies in recording, using a recording device, sound waves generated during the departure of the impactor from the shaft of the installation and its further collision with the shaping punch, followed by finding the time ∆t during which the impactor travels the distance L between two known points of its trajectory. In turn, the value ∆t is defined as the difference between the recording time of the sound wave generated by the departure of the impactor from the shaft of the installation, and the recording time of the sound wave generated by the collision of the impactor with the shaping punch. The initial deformation rate, registered using the developed technique during the implementation of the process of high-speed forging of rod products, was v0 = 115.46 m/s.
