Method for Determining the Feed Speed ​​of the Core Roll Driven by the Feed in the Ring Rolling Process

Abstract

A method for determining the feed rate of the core roll driven by the feed rate in the ring rolling process. Firstly, the biting condition and the rolling through condition of the ring rolling process are considered, and the starting rolling, steady rolling, reduction, The curve of the feed amount changing in real time with the outer diameter of the ring in the four stages of the full circle; secondly, determine the equation of the feed amount at each stage; finally, reverse the solution according to the mathematical relationship between the core roller feed speed and the feed amount Core roll feed speed, to realize the determination of the core roll feed speed driven by the feed amount in the ring rolling process. In this method, the feed rate in the ring rolling process is changed according to the four stages of start rolling, steady rolling, reduction and full circle, and the core roll feed speed suitable for the control requirements of the ring rolling equipment is obtained, thereby improving the stability and stability of the ring rolling process. The problem of forming quality meets the control requirements of the ring rolling equipment in the actual ring rolling process. It is efficient and scientific and reliable, and provides important technical support for the optimal design and robust control of the ring rolling process.

Description

technical field [0001] The invention belongs to the field of ring rolling forming processing, and in particular relates to a method for determining the feed speed of a core roll driven by the feed amount in the ring rolling process. Background technique [0002] In the ring rolling forming process, the feed speed of the mandrel roll is an important parameter affecting the feed rate, which has an important impact on the stability of the ring rolling process and the quality of the formed ring. The greater the feed speed of the core roll, the greater the feed per revolution, otherwise the smaller the feed per revolution. When the feed speed of the core roll is too high, the feed amount per revolution is too large to meet the biting conditions of the ring rolling process, so that the ring cannot be bitten into the rolling pass smoothly, and the feed speed of the core roll is too small, and the feed rate per revolution is too small. The feed rate is too small and does not meet t...
