Metal plate rolling bending forming springback compensation mechanism

Abstract

The invention discloses a metal plate rolling bending forming springback compensation mechanism. The springback compensation mechanism comprises a transverse moving base, a servo motor, a first gear,a second gear, an angle adjusting seat and rollers, wherein the transverse moving base has a function of sliding in the horizontal direction, the servo motor is arranged on the transverse moving base,the first gear is fixed on a rotating shaft of the servo motor, the second gear is meshed with the first gear, the number of teeth of the second gear is larger than that of the first gear, the angleadjusting seat is fixed to a rotating shaft of the second gear, the rollers are arranged on the angle adjusting seat, rotating shafts of the rollers are perpendicular to the rotating shaft of the second gear, and when the servo motor drives the first gear and the second gear to rotate, the angle adjusting seat is used for adjusting the rolling angles of the rollers along with the rotation of the second gear. According to the springback compensation mechanism, the angles of the rollers can be changed under driving of the servo motor so as to achieve angle bending on a metal plate which is located on a line, the springback angel or edge width is detected under the cooperation with a sensor, the detected springback angle or edge width is input into a programmable controller, and feedback control is carried out on a bending roller so as to achieve bending on the springback.

Description

technical field [0001] The invention relates to a springback compensating mechanism, in particular to a springback compensating mechanism for sheet metal rolling and bending. Background technique [0002] The so-called "roller forming" is a forming technology in which metal sheets are continuously bent laterally by multi-stage rollers to form profiles with special cross-sections. It has a wide range of uses, and is widely used in metal products in industries such as automobiles, steel pipes, drawer slides, and construction. Roll forming method. [0003] In the current springback compensation method of roll forming, the angle of the rolls is fixed and cannot be adjusted freely. Once the angle prediction is wrong, the rolls must be remade, and the angle springback of high-strength steel is difficult to accurately predict. Remaking rolls is time consuming and costly. [0004] In view of the above problems, it is necessary to have profile rollers that can adjust the angle to i...
