The invention discloses an automatic shaping system for profile multi-point stretch-bending die head bodies and belongs to the field of mechanical engineering. The system comprises a workbench and a plurality of die units, wherein the die units are controlled to move horizontally through ball screws, a hydraulic telescopic mechanism is arranged inside each die unit, and the lower end of each hydraulic telescopic mechanism is connected with a horizontal shaping motor; a rotation angle detection device is arranged on a central shaft of each horizontal shaping motor; the upper end of each hydraulic telescopic mechanism is provided with a rectangular groove; the middle of the rectangular groove at the upper end of each hydraulic telescopic mechanism is provided with a die head body base; the die head body bases rotate along with the rotation of the horizontal shaping motors; a vertical shaping motor is arranged in each die head body base; the output end of each vertical shaping motor is connected with the corresponding die head body; and the vertical shaping motors drive the die head bodies to rotate so as to achieve the torsion required during vertical bending forming and die pasting.The system not only saves the shaping time and improves the production efficiency, but also improves the forming precision of a workpiece.
Description
technical field [0001] The invention discloses an automatic shape adjustment system for the head body of a profile multi-point stretch bending die, which relates to profile plastic processing, multi-segment curvature metal profile stretch forming and a mechanical automatic control device, belongs to the field of mechanical engineering, and is especially suitable for designing metal profile stretch bending The multi-point forming method can be widely used in the production of three-dimensional curved structural parts in profile space. Background technique [0002] With the requirement of lightweight components, the demand for three-dimensional curved structural parts in profile space is increasing. Large-scale machinery and equipment used in aerospace, rail trains and other fields have higher and higher requirements for profiles with multiple curvatures, long lengths, and complex cross-sectional shapes. Therefore, the forming efficiency and forming accuracy of parts are beco...
