Method and device for strain straightening of work
专利汇可以提供Method and device for strain straightening of work专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve the straightening accuracy and product yield by measuring the relation of a proper deformation amt. and permanent deformation amt. on each straightening work, operating a regression curve as well and estimating the deformation amt. to be given to the straightening work based thereon.
CONSTITUTION: The supporting device I of a bar like body work 1, a deflection amt. detection device II and pressurizing device III are respectively provided and a pressure control device IV and automatic arithmetic and control unit V are respectively arranged as well. The bending amt., maximum bending position and direction of the work 1 are decided by an arithmetic unit 9 by rotating the work 1 with a roller 2 in advance and inputted to the pressure control device IV. The necessary push-in amt. is then given by the pressure device III and after measuring the deformation amt. by a deformation amt. measuring instrument 7-1 a permanent deformation amt. is detected. Moreover, the work 1 pressurizing is repeatedly effected by finding the relative regression curve of the permanent deformation amt. and proper deformation amt. Since the pressurizing is performed by finding the regression curve on each work the straightening accuracy and product yield are improved.
