This invention discloses a laser-shock-assisted creep aging forming method for thin-walled components with complex curvature. The method includes: simulating and obtaining difficult-to-form regions; performing laser shock on the difficult-to-form regions of a large-size aluminum alloy thin-walled component sheet; wrapping and fixing a breathable felt around the impacted component; placing the component in a sealed space formed between a vacuum bag and the mold surface; evacuating the sealed space; and then sending the mold into an autoclave for creep aging. After completion, the component springs back, yielding the target surface. This method uses a laser to impact localized areas of a large-size aluminum alloy thin-walled component, introducing dislocations while achieving pre-forming. This provides a good surface foundation for subsequent high-precision creep aging forming of the component, and is suitable for forming parts with complex curvature.

The invention discloses a flexible bomb holding protection mechanism during rocket bomb or missile transportation. The flexible bomb holding protection mechanism comprises a supporting plate; one end of the connecting rod is connected with the supporting plate, the other end is connected with the dome-shaped shell at the bottom, and a supporting ball is arranged in the middle; the shell is used for guiding the connecting rod and mounting the dome-shaped shell, and an air chamber is formed between the shell and the dome-shaped shell, so that the dome-shaped shell is inflated and deflated, and switching of two steady states of the dome-shaped shell is realized; four dome-shaped shells are arranged at the side ends, and one dome-shaped shell is arranged at the bottom; the dome-shaped shell at the side end and the bottom forms a throat structure and is sealed by the shell; when the air chamber is in an inflated state, the throat structure is in contact with the supporting ball, and axial movement of the connecting rod is supported through elasticity of the dome-shaped shell, so that the bomb holding protection mechanism is in an elastic holding state; when the air chamber is in a negative pressure state, the four dome-shaped shells at the side ends turn over and are separated from the supporting balls, and the dome-shaped shell at the bottom drives the connecting rods to contract, so that the bomb holding protection mechanism is in an open state. Transportation protection is provided, meanwhile, quick opening can be achieved, and launching is not affected.

The invention relates to the technical field of photovoltaic supports, and particularly discloses an anti-seismic and anti-displacement photovoltaic support which comprises a base frame, a first anti-seismic rod is arranged at the upper end of the base frame, a second anti-seismic rod is arranged at the upper end of the base frame, an anti-seismic force unloading assembly is arranged at the upper end of the second anti-seismic rod, and connecting assemblies are arranged at the upper ends of the anti-seismic force unloading assembly and the first anti-seismic rod correspondingly. A third anti-seismic rod is arranged between the base frame and the second anti-seismic rod, and the base frame, the second anti-seismic rod and the third anti-seismic rod form a triangular structure; force is effectively unloaded, springback is prevented, the hidden crack risk of the photovoltaic equipment is reduced, the secondary damage risk of springback is reduced, cooperative shock resistance is achieved, the overall stability of the photovoltaic equipment is improved, one-way dissipation and controlled reset of vibration energy are achieved, and secondary impact damage caused by instantaneous springback of a traditional spring is reduced.

This invention relates to the field of H-steel pre-assembly welding, and more particularly to an end positioning mechanism for an H-steel pre-assembly line. The mechanism includes a track frame, a web positioning assembly, and two sets of wing plate positioning assemblies. A movable support and a fixed support opposite to the movable support are respectively mounted on the track frame. The two sets of wing plate positioning assemblies are respectively mounted on the fixed support and the movable support. A web support is fixedly mounted on one side of the fixed support. The web positioning assembly is mounted on the web support. The web positioning assembly includes a web positioning support plate and a web baffle disposed on the side of the web positioning support plate. The wing plate positioning assembly includes a wing plate positioning support plate and a wing plate baffle disposed on the side of the wing plate positioning support plate. This invention provides a damping force proportional to the speed by adding a hysteresis damping unit at the floating stop, ensuring a smooth buffering process without rebound. This ensures that after the kinetic energy is lost, the stop near the conveying end face is completely in contact with the baffle end face, effectively preventing poor positioning accuracy.

This utility model discloses a spiral flexible hose, including a hose skin. A connecting rib structure is provided on the hose skin, and the connecting rib structure is wound synchronously with the hose skin, resulting in a flexible hose of different shapes on the inner wall and a spiral rib formed on the outer wall. This utility model, by providing a connecting rib structure on the hose skin, allows the hose skin to be wound to form a flexible inner wall, and a spiral rib formed on the outer wall. The connecting rib structure includes a plastic rib and a metal wire, with the metal wire located inside the plastic rib. This structure, through the interaction of the connecting rib and the hose skin, can produce flexible hoses with various irregular cross-sections, including rectangular, elliptical, rounded ends with a rectangular middle, and rounded ends with an elliptical middle, but not limited to these shapes, thus improving applicability. The hose skin enables the flexible hose to be wound into various shapes, and the connecting rib structure assists in supporting the formed flexible hose after winding, making it less prone to deformation.
