Study And Analysis Of Accuracy About Cold Rolling Forming Of Steel

Cold rolling forming technical is the quickly developing engineering manufacturing technical in the world presently and it has gradually formed one technological science. This article briefly introduces cold rolling technical status and its developing trend. It analyzes stresses relation equation of bending wide plate and analyzes the effect for bending recovery amount under free bending condition according to differential coefficient balance equation, plastic condition , plane strain condition etc. theories and methods. Through experiment,the author has summed up the related parameters in bending recovery amount and in rolling procedure and put forward the relevant methods to improve manufacturing precision..
