Abstract

The invention discloses a nickel-based alloy rotary forging strengthening effect prediction method, which realizes effect prediction through a nickel-based alloy rotary forging strengthening process database, and comprises the following steps: step 1, establishing a nickel-based alloy rotary forging strengthening process database, and step 2, according to the strengthening effect of a nickel-based alloy material preset value, calculating the nickel-based alloy rotary forging strengthening effect according to the nickel-based alloy material preset value. A set of initial swing grinding process parameters are obtained through database query; 3, the nickel-based alloy rotary forging strengthening process database transmits the process data scheme to a nickel-based alloy rotary forging forming control system and a computer software simulation system through a set control center; 4, according to the difference value of the experimental data and the simulation data, the nickel-based alloy rotary forging strengthening process database reselects rotary forging parameters based on the response relation; and 5, an experiment is directly conducted according to the reselected rotary forging parameters, the steps 1-4 are repeated till the error is controlled within 5%, and it is considered that the process parameters can achieve the preset strengthening effect.

Description

technical field [0001] The invention relates to the technical field of metal plastic forming parameters, in particular to a method and a system for predicting the strengthening effect of pendulum forging of nickel-based alloys. Background technique [0002] Pendulum forming is a processing method in which the upper die is used to locally pressurize the blank and continuously roll around the center. It and spinning are both incremental forming technologies. Local plastic deformation is achieved through the contact between the die and the workpiece. Through this local plastic deformation The cumulative realization takes shape. The process involves many process parameters such as motion trajectory, swing speed, feed speed, feed displacement, geometric dimensions, material properties and so on. The process parameters in the local plastic forming process all affect the final forming result of the metal. This process can not only avoid various defects caused by heating during ho...
