Segmented multi-metal insert cable cover forming method and forming die

Abstract

The invention discloses a sectional type multi-metal insert cable cover forming method and a forming die pressing die. The sectional type multi-metal insert cable cover forming method comprises the following steps of determining a sectional structure; determining the lap joint structures and the lamp joint sizes of the joints of the front section, the middle section and the rear section of a cablecover, and a cable cover assembling element; determining the structure of the assembling element; determining the blank structure; determining the positioning mode and pressure forming direction of metal inserts; carrying out pressure forming; carrying out thermal correction; carrying out lap joint on the formed cable; and carrying out trial assembly and repair. A segmented compression molding scheme is adopted by the cable cover, so that the dependence on large-scale pressure equipment is eliminated, the design difficulty of the die is reduced, and meanwhile, the defect of large warping deformation after integral die pressing is avoided, and the assembling precision of the cable cover can be effectively improved; and the metal inserts are embedded in the cable cover, so that the assembling strength of the cable cover and the elastic body structure support is met; and meanwhile, the assembling part is protected by a cover plate, so that the overall heat protection effect of the cablecover is improved.

Description

technical field [0001] The invention belongs to the technical field of processing, molding and assembling of an air-to-surface missile projectile structure cable cover, and specifically refers to a forming method and a molding die for a sectioned multi-metal insert cable cover. Background technique [0002] Air-to-surface missiles are the main offensive weapons of combat (strategic) bombers, attack aircraft, armed helicopters, anti-submarine aircraft and unmanned attack aircraft. Area suppression, battlefield air interdiction, air strikes, and targeted clearing play an important role in combat missions. They are the core factor of the precision strike system in modern warfare and the decisive force that determines the outcome of a local war. [0003] Cables and cable covers are important components of air-to-surface missiles, which can provide electrical interfaces and information transmission channels for the connection between components in the missile; provide safe isolat...

AI Technical Summary

Problems solved by technology

[0004] The cable cover materials are generally aluminum alloy or stainless steel and carbon fiber (layer forming), among which aluminum alloy and stainless steel materials are low in cost and easy to process, but have poor environmental adaptability (poor heat insulation and erosion resistance); the cable cover formed by carbon fiber layer Light weight, high molding efficiency, but low erosion resistance

[0005] Therefore, the air-to-surface missile cable cover needs to meet the requirements of function, structure, and use environment at the same time, and its engineering development technology is relatively difficult
