[0001] The utility model relates to the technical field of plastic forming of tensile and compressive thin plates, and more specifically, to a new type of comprehensive plastic forming equipment for tensile and compressive thin plates. Background Technique
[0002] At present, in recent years, many special-shaped buildings have been added in the domestic and foreign construction industries. These buildings require a large number of metal curved curtain wall decorative plates. These decorative plates have various shapes and are mostly thin plate parts with variable curvature. The equipment for producing thin plate parts with variable curvature is not yet mature in China. Creatively, the hydraulic press, skin stretcher, and multi-point die cannot be combined together, resulting in relatively weak stretching and pressing processes for metal thin plates, and unable to meet the usage requirements of aviation parts and metal curved curtain wall decorative plates. Content of the Utility Model
[0003] In order to make up for the above deficiencies, the utility model provides a new type of comprehensive plastic forming equipment for tensile and compressive thin plates, aiming to improve the relatively weak stretching and pressing processes for metal thin plates and the problem that they cannot meet the usage requirements of aviation parts and metal curved curtain wall decorative plates.
[0004] The utility model is implemented as follows: A new type of comprehensive plastic forming equipment for tensile and compressive thin plates includes a foundation. On the top of the foundation, tie rods are symmetrically and fixedly installed. On the tie rods, a lower beam is fixedly installed. On the lower beam, a lower lifting cylinder is fixedly installed. The output end of the lower lifting cylinder is fixedly installed with a lower workbench. On the top of the lower workbench, a lower multi-point die is fixedly installed. On both sides of the lower workbench, guide rails are fixedly installed. On the guide rails, a clamping assembly is installed. On the top ends of the two tie rods, an upper beam is fixedly installed. Inside the upper beam, upper lifting cylinders are symmetrically and fixedly installed. The output ends of the upper lifting cylinders are fixedly installed with an upper workbench. On the bottom end of the upper workbench, an upper multi-point die is fixedly installed.
[0005] In the preferred technical solution of the utility model, the lower multi-point die and the upper multi-point die are symmetric and cooperate with each other, and the lower multi-point die and the upper multi-point die are arranged at the center of the two tie rods.
[0006] In the preferred technical solution of the utility model, the guide rails are slidably installed on the tie rods.
[0007] In the preferred technical solution of the utility model, an installation groove is provided on the top of the foundation. The tie rods are fixedly installed at the bottom end of the inner wall of the installation groove. When the lower lifting cylinder contracts and drives the lower workbench to move to the lowest position, the bottom end of the guide rail is on the same plane as the top of the foundation.
[0008] In a preferred technical solution of the present utility model, the clamping assembly includes a pushing cylinder, a bracket, a pitching cylinder and a large clamp head. The pushing cylinders are symmetrically and fixedly installed at the tops of the two guide rails. The output end of the pushing cylinder is fixedly installed with the bracket. The pitching cylinder and the large clamp head are hinged inside the bracket, and the output end of the pitching cylinder is hinged to one end of the large clamp head.
[0009] In a preferred technical solution of the present utility model, the bracket is slidably installed at the top of the guide rail. A limiting strip is fixedly installed at the bottom end of the bracket. The limiting strip is T-shaped. A chute matching the limiting strip is provided at the top of the guide rail, and the limiting strip is slidably connected to the inner wall of the chute.
[0010] In a preferred technical solution of the present utility model, columns are symmetrically and fixedly installed between the lower beam and the upper beam. The guide rails are slidably installed on the columns, and the columns are symmetrically arranged outside the two tie rods.
[0011] The beneficial effect of the present utility model is as follows: A new type of comprehensive tension and compression thin plate plastic forming equipment obtained by the above design of the present utility model places the workpiece in the lower multi-point die, and starts the pushing cylinder to drive the bracket to move to adjust the distance between the large clamp head and the workpiece until the large clamp head clamps both sides of the workpiece. Then start the pitching cylinder to drive the large clamp head to rotate to bend and stretch the workpiece. Finally, start the lower lifting cylinder and the upper lifting cylinder at the same time, that is, the upper multi-point die and the lower multi-point die move relative to each other for processing. This equipment can provide a greater pressing force in the vertical direction to realize the plastic deformation of plate parts, and can provide a drawing force sufficient for the yield deformation of parts in the horizontal direction. Through plastic deformation in the horizontal and vertical directions, the production of parts with various curvatures is completed. BRIEF DESCRIPTION OF THE DRAWINGS
