Embodiment Construction

[0048] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0049] A small-caliber, long-dimension non-equal thickness and thin rectangular pipe fitting forming tooling. The mandrel can be disassembled step by step in the three directions of length and cross-section. The order of the corners "disassembles" the mandrel and comes out from the inside of the pipe fitting, solving the problem of difficult demoulding of long-sized, small-diameter thin-shaped pipe fittings. This operation is simple and convenient, and there is no damage to the pipe fittings during the demoulding process. And the disassembled tooling can be quickly assembled and reused.

[0050] In addition, the two ports of the mold are designed universally, and the key functions of the sealing mechanism, pressure charging interface and demoulding of the pipe fittings are all designed at the two ends. For the molding of pipe f...

Abstract

The invention belongs to the field of forming composite material pipe fittings, and is applied to the development of low-weight, long-size, small-caliber thin-walled rectangular pipe fittings such as a string-tensioned semi-rigid frame substrate for spacecraft. The invention provides a small-caliber, long-dimension non-equal-thickness and thin-shaped rectangular pipe fitting forming tooling and method, and its good sealing performance, thermal stability and attachment performance solve the problem that the corner pressure of non-equal-thickness pipe fittings is not in place. Problems, and the flatness of the inner surface of the pipe is improved very well.

Description

technical field [0001] The invention relates to a small-diameter, long-dimension non-equal thickness and thin rectangular pipe fitting forming tool and method, belonging to the technical field of composite material pipe fitting forming. Background technique [0002] The main frame of the solar wing of the Dongwu platform is a string-type semi-rigid substrate, which is composed of a number of high-modulus carbon fiber high-temperature cyanate composite materials and thin-walled rectangular pipes. In order to meet the requirements of light weight and load bearing, the pipe fittings are of unequal wall thickness configuration, the wall thickness in the main bearing direction is 1mm, and the wall thickness in the non-loading direction is 0.6mm. The length of the pipe fitting is 2520mm, and the section size is only 20mm, which is a thin pipe fitting with a large aspect ratio. After the pipe fittings are formed, the accuracy of the external dimensions is required to be ±0.05mm, a...
