FIG. 1 is a perspective view of a heat treatment and shape-retaining device for the bottom of a tank of a carrier rocket tank according to one embodiment of the present invention; FIG. 2 is a side view of a heat treatment conformal apparatus for a bottom of a carrier rocket tank according to yet another embodiment of the present invention; FIG. 3 is a top view of another embodiment of the heat treatment conformal apparatus for the bottom of a carrier rocket tank of the present invention; FIG. 4 is a cross-sectional view taken in rotation A-A of FIG. 3; FIG. 5 is an enlarged view of B in FIG. 4; fig. 6 is an enlarged view of C in fig. 4.
As shown in figure 1, the invention provides a heat treatment shape-preserving device for the bottom of a storage box of a carrier rocket, which comprises: an annular support frame 100 comprising an outer support ring 101, an inner support ring 102 and an intermediate connection frame 103, the intermediate connection frame 103 connecting the outer support ring 101 and the inner support ring 102; the profile supporting frame 200, which is positioned on the annular supporting frame 100, comprises a profile adjusting component 201 and a profile supporting plate 202 with a shape adapting to the bottom of the storage tank, wherein the profile adjusting component 201 is used for driving the profile supporting plate 202 to move along the radial direction of the annular supporting frame 100 so as to adaptively support the bottom surface of the storage tank.
Particularly, the bottom of the storage tank of the carrier rocket adopts an integral spinning manufacturing technology, and the technology has great advantages in the aspects of structure weight reduction, production efficiency, high reliability and the like and becomes a development trend in the field of manufacturing of low-temperature fuel storage tanks of rockets. The bottom of the common storage tank adopts heat treatment strengthening type aluminum alloy such as aluminum copper, aluminum lithium and the like, and the performance strengthening purpose can be achieved only by solution quenching and aging heat treatment after the integral spinning forming. Taking 2A14 aluminum alloy as an example, the material is required to be quickly (generally less than or equal to 10s) transferred to normal temperature water for cooling (solution quenching) after being subjected to heat preservation at the high temperature of 500 ℃ for 1-2h, and then subjected to heat preservation at the temperature of 160-. Therefore, the solution quenching process is a violent high-low temperature alternating process, which is accompanied by huge thermal stress, resulting in severe deformation of the product, especially in the product with a large-size thin-wall structure. Taking the 2219 and 2195 aluminum alloy storage box bottom with the diameter of the opening part of 3350mm and the thickness of the blank more than or equal to 20mm as an example, the roundness of the opening part of the product after solution quenching reaches more than 10mm, and the corresponding molded surface of the product also can generate larger deformation along with the roundness change of the opening part, thereby bringing adverse effects to the machining sequence of subsequent products.
In the embodiment, the heat treatment shape-preserving device for the bottom of the carrier rocket storage tank has a rigid constraint function aiming at the deformation of the bottom of the storage tank in the heat treatment process, wherein the annular support frame 100 is used for providing the integral bearing for the bottom of the carrier rocket storage tank, and the structure that the outer support ring 101 and the inner support ring 102 are connected by the intermediate connecting frame 103 can accelerate the heat conduction in the heat treatment process and meet the reliability requirement for bearing the bottom of the carrier rocket storage tank.
Wherein the profile support frame 200 is the main conformal component secured to the annular support frame 100. Before the heat treatment process begins, the bottom of the carrier rocket tank is inverted on the profile support frame 200, so the profile support plates 202 in the profile support frame 200 are designed to conform to the circular arc shape of the tank bottom. For example, the profile support plate 202 can be adjusted to completely conform to the bottom of the tank, thereby ensuring that the amount of deformation of the tank bottom during heat treatment is controlled. The profile adjusting assembly 201 in the profile supporting frame 200 is used for adjusting the profile supporting plate 202 to adaptively support the bottom surface of the storage tank, adjusting the bottom of the storage tank to a theoretical profile and locking by driving the profile supporting plate 202 to move along the radial direction of the annular supporting frame 100, and then performing heat treatment on the bottom of the storage tank. The bottom of the storage tank can be effectively supported by adjusting the molded surface support plate to a proper position, so that the deformation of the bottom of the storage tank caused by thermal stress can be greatly reduced in the heat treatment, namely the solid solution strengthening process.
