The strip shape defect is caused by the different internal stress in the width direction of the strip, which causes a small length difference between the longitudinal fibers adjacent to the width direction. In order to obtain a flat strip, the length direction of the strip should be applied only to stress beyond the yield limit, so that the length and direction of the longitudinal fiber in the strip tend to be the same and the internal stress are consistent. Achieve leveling purposes.
The structural innovation of stretch bending machine refers to the structural improvement of a stretch bending machine. The upper side of the frame is connected with a large disk, and the front end of the frame is symmetrically pivoted with two rotating arms. The upper rail surface of the rotating arm is equipped with a movable cylinder seat with a chuck. One end of the pull-bend cylinder for driving the rotating arm is hinged at the front part of the frame, and the other end is hinged at the inner flange of the rotating arm by the outer end of the piston rod. An active triangular relationship is formed between the frame, the rotary arm and the tension bending oil cylinder on the outer part of the rotating arm. The pull-bend cylinder does not need to pass through the middle of the revolving arm, so the revolving arm does not need to be hollowed out in the middle of the revolving arm to ensure the integrality of the revolving arm and strengthen the strength and rigidity of the revolving arm.
