Among them, the three-dimensional bending of the multi-curvature profile is often processed by stretch bending. However, in the existing multipoint three-dimensional stretch bending forming process, after the clamp completes the bending forming in the horizontal direction, the clamp needs to drive the profile and the multipoint mold to move in the vertical direction at the same time, the gravity and friction of the multipoint mold aggravate the load of the clamps at two ends, the motion track of the clamp is disturbed, the profile cannot be completely attached to the mold, and the forming precision on a vertical plane is difficult to control. In addition, the clamp is used as a unique power output source in the forming process, and the bending of a complex target geometric shape, such as the three-dimensional bending of a multi-curvature section bar, cannot be realized, so that the forming requirement of rapid development of modern high-end equipment cannot be met.
Therefore, the utility model discloses based on the thought of multiple spot shaping, invented a multiple curvature section bar multiple spot complicated bending shaping school shape integrated device, solved the problem that clamp load changes and brings the shaping precision reduction. By adding the actuating mechanism at each multi-point mould position, the forming and shape correction of the complex three-dimensional bending part are realized, the forming efficiency is improved, and the forming device has wide application prospect and market space.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the multi-point complex bending forming and shape correcting integrated device for the multi-curvature section is used for realizing complex three-dimensional bending forming and shape correcting of the multi-curvature section and improving forming precision and production efficiency.
The utility model provides a many curvatures section bar multiple spot complicated bending take shape school shape integrated device for many curvatures section bar take shape. The device consists of a frame, a workbench, unit bodies and clamps. The multi-curvature section multi-point complex bending forming and shape correcting integrated device is characterized in that the rack is formed by welding rectangular steel, the workbench is arranged on the rack, and the unit bodies are arranged on the workbench. In the forming process, the shape adjustment in the horizontal direction is realized by driving of a third hydraulic cylinder and a second motor, and then the section is driven by a clamp to axially stretch and attach to the die in the horizontal direction. At the moment, the sectional material cannot be completely attached to the die locally due to the self mechanical bending deformation characteristic of the sectional material. Therefore, the first hydraulic cylinders drive the pressure heads to contact the section bars on the plurality of unit bodies, so that the section bars are completely attached to the die, the shape correction work of the section bars is completed, and the forming precision is improved. After the forming in the horizontal direction, the second hydraulic cylinders on the plurality of unit bodies provide power to complete the forming of the vertical plane. Therefore, qualified three-dimensional bent parts can be formed, and the change of the section shape and the type of the section only needs to replace the die head without replacing other parts, so that the manufacturing cost of the die is greatly saved.
