Abstract
PURPOSE: To improve the straightening accuracy, and to shorten the cycle-time of straightening work, by installing the circuit to always renew the elastic constant to be used at the straightening work.
CONSTITUTION: At the bend straightener to use the elastic constant of the long size material, the circuit is installed on purpose to memorize the press force and the bend at the end point of pressing action during the straightening work and the bend after finishing the straightening work, to operate the elastic constant, and to renew the elastic constant data before entering next straightening work. By using this circuit constitution, the straightening work is repeated carrying out the operation and renewal of the elastic constant until the post-straightening bend becomes less than the allowable limit. By employing this straightener, the quality of the long size product is improved, and the cost reduction of the straightening work can be contrived.
