Abstract:

Springback is the key technique for the control of the computer numeric control (CNC) frame bender. Research had been done for the springback of frame cool bend. This paper proposed the regression analysis results with samples of frame bend production recorded in the shipyard. The characteristics of the frame bending with trial-and-error method had been analyzed. Based on the regression function of the sample, this paper proposed a forming control method by excess bending and the amount of control parameter can be calculated with the regression function. In this way, one or two operations were needed to achieve the acceptable shape of the section. This method can increase the efficiency of frame bend production obviously. A new control system had been proposed with this control method, the system had been applied in the frame bender in shipyard, and the production efficiency had been increased effectively.
