Abstract
The invention discloses a stainless steel-aluminum double-metal ring part rolling forming method. The method comprises the steps: firstly upsetting, punching and pre-rolling stainless steel and an aluminum alloy rod into a stainless steel ring blank and an aluminum alloy ring blank; and sleeving the aluminum alloy ring part with the stainless steel ring blank and placing the two on a ring rolling machine to be rolled to obtain the a stainless steel-aluminum double-metal ring part. According to the method, a rolling deformation resistance specific value is derived by virtue of a rolling rate of double metals to determine the rolling deformation temperature, so as to separately heat the metals to corresponding temperatures to be rolled and formed, thereby obtaining the double metal ring part which is good in performance and dimension. The method is used for double metal ring part rolling forming.
