Problems solved by technology
[0005] For the needs of research on different bending curvature characteristics in the laboratory, or the need to test molds for different diameter models in production practice, although it may only be required for a single curvature, it requires a wide range of curvature radius adjustment and high forming accuracy. The straightness of the busbar is good, and the above patents cannot meet the requirements of these molds

Embodiment Construction
[0025] Such as Figure 1 to Figure 3 As shown, this embodiment discloses a metal sheet creep bending forming die, which mainly includes a base 1, a baffle box 2, a height-adjustable support member 3, a distance adjustment block 4, a side baffle 5, and a profile pad 6 .
[0026] The base 1 is a box-shaped beam base, which is a closed box-shaped structure surrounded by the upper base plate 11, the lower base plate 12 and the surrounding side plates, wherein the upper base plate 11 is provided with four strip grooves 111, which are respectively about the upper base plate 11. The center planes in the length direction and the width direction are symmetrical, and two threaded holes are opened on the center plane in the length direction of the upper bottom plate 11 corresponding to the positions of the strip grooves 111 . In order to ensure the strength of the base, a reinforcing rib plate 13 is arranged between the upper base plate and the lower base plate.
[0027] The baffle box...

Abstract
The invention discloses a creep bend molding die for a metal plate. The creep bend molding die comprises a base, a profile cushion plate and supporting components of the profile cushion plate. The supporting components of the profile cushion plate are connected to the base. Each supporting component of the profile cushion plate comprises a fixed component body and a movable component body. The fixed component bodies are connected to the two ends of the base in the length direction. The movable component bodies are connected between the two fixed component bodies on the base. The height positions of the movable component bodies and the connection positions of the movable component bodies on the base are adjustable. The two ends of the profile cushion plate are arranged on the upper sides of the fixed component bodies, and the middle segment is arranged at the upper ends of the movable component bodies. The supporting profile cushion plate of different curvatures is formed by adjusting the height of the movable component bodies and the connection positions, and a workpiece to be molded is placed on the profile cushion plate.
Description
technical field [0001] The invention relates to a metal material forming process, in particular to a metal plate creep bending forming die used in the metal material forming process. Background technique [0002] Creep aging forming is an emerging metal material forming process, which uses the creep or stress relaxation deformation and aging strengthening characteristics of metals to complete aging strengthening heat treatment while forming components to obtain excellent mechanical properties and realize shape-property collaborative manufacturing. . The wall panels of launch vehicle tanks and aerospace vehicles are all the application objects of creep aging forming technology. [0003] The creep aging forming process includes the general bending forming molding process, but the molding method is generally realized by vacuuming the sealed plastic bag. Then heat according to the pre-designed temperature-time curve, keep warm for a certain period of time after reaching the pr...
