Embodiment 1

[0031] The present invention provides a kind of integral spinning forming process equipment for the bottom of the storage tank through improvement, such as Figure 1-Figure 4 As shown in the figure, it includes a composite tail top device, a positioning device and a spinning mandrel 3. The center of the spinning mandrel 3 is provided with a dosing rod 10, and one end of the spinning mandrel 3 is connected to the spinning mandrel by a connecting flange. The main shaft of the pressing equipment 14 is fixedly connected, the composite tail top device is installed on the equipment tail top 7, the positioning device is arranged on the spinning mandrel 3, and the positioning device is used to align the relative position of the spinning wheel and the spinning mandrel ; Spinning equipment 14, equipment ejection cylinder 13 and equipment tail top 7 are all prior art, and will not be repeated here;

[0032] The composite tail top device includes an outer jack block 5, an outer tail jack ...

Embodiment 2

[0041] Based on the integral spinning forming process equipment for the tank bottom provided in the first embodiment of the present application, the second embodiment of the present application proposes another integral spinning forming process equipment for the tank bottom. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0042] The second embodiment of the present invention will be further described below in conjunction with the drawings and implementation methods.

[0043] Specifically, the material stripping device 1 is two stripping rings 2 in a semicircular structure, and a load-bearing boss fixedly connected with the two stripping rings 2 is provided between the two stripping rings 2, and the load-bearing The boss is connected by bolts and nuts to form a complete ring; the worker manually installs the stripping ring 2 on the sp...

Abstract

The invention discloses an integral spinning forming process device for a storage box bottom, and belongs to the technical field of spinning forming of the storage box bottom. The device comprises a composite tail top device, a positioning device and a spinning core mold, wherein a material fixing rod is arranged in the center of the spinning core mold; one end of the spinning core mold is fixedlyconnected with a main shaft of spinning equipment through a connecting flange; the positioning device is arranged on the spinning core mold, and is used for aligning relative positions of a spinningwheel and the spinning core mold; the composite tail top device comprises an outer top block, an outer tail top, an inner tail top and an inner top block; the inner tail top and the inner top block are fixedly connected through a bolt; the inner tail top is fixed on a device tail top; and the outer tail top and the outer top block are fixedly connected through a bolt. The composite tail top devicecan increase the pressing friction force on blanks to effectively prevent the slip phenomenon in the product forming process; and the device can realize ejection of products out of the spinning coremold through a material return device.

Description

technical field [0001] The invention relates to the technical field of spinning forming of the bottom of a storage tank, in particular to an integral spinning forming process equipment for the bottom of a storage tank. Background technique [0002] The bottom of the tank is an important structural component of the fuel tank of the launch vehicle, which bears complex dynamic loads under service conditions, and requires high reliability of mechanical properties. The rocket booster storage tank is made of 5A06 aluminum alloy material, and each bottom of the tank is assembled and welded by forming a top cover 17 and 6 melon petals 18 separately; figure 1 As shown, the melon petals 18 and the top cover 17 at the bottom of the box are first mechanically drawn with a mold with bead ribs, and then the mold is replaced, and the forming of the flanged hole is completed by using multiple mechanical convex holes. The process flow is about 23 processes, plus annealing and manual grindin...
