Abstract

PURPOSE:To improve the efficiency and accuracy in straightening by detecting the reaction force exerted on a straightening jig from a material to be straightened, calculating the bend amt. of the material to be straightened as well and executing the necessary straightening based on the bend amt. arithmetic value. CONSTITUTION:More than three straightening units 2 at least are provided in a line at about equal intervals for the material 1 to be straightened. The pressure sensor 9 of a distortion gage, etc., is then arranged respectively on each straightening jig 4, 5 constituting the unit 2. The material 1 to be straightened having the bend to the straightened is interposed by the straightening jig 4, 5 and the jigs 4, 5 are varied until the state of the bend being eliminated. In this case, the pressure sensors 9, 10 detect the pressure against the bending amt. Based on the signal of the sensors 9, 10, the initial bend amt. of the material 1 is operated and each straightening jig 4, 5 is driven to straighten the material 1. Consequently, the efficiency and accuracy in straightening are improved.
