Problems solved by technology

The irregular straight rod formed by heating pultrusion is not completely uniform in the axial direction, so there will be many irregular defects on the surface of the straight rod that affect the mechanical properties, and the heating pultrusion method will be affected by the surrounding thermal environment in space

Abstract

The invention relates to a space structure rod piece on-orbit forming device which comprises a mounting platform, a pipe winding forming demolding mechanism, a feeding mechanism, a welding mechanism and a pipe clamping and pushing-out mechanism, the pipe winding forming demolding mechanism is arranged on the mounting platform, and a support is arranged on one side of the pipe winding forming demolding mechanism. The feeding mechanism, the welding mechanism and the pipe clamping and pushing-out mechanism can be movably arranged on the support in the axial direction of the pipe winding forming demolding mechanism, and a discharging port of the feeding mechanism corresponds to the pipe winding forming demolding mechanism. The welding mechanism and the pipe clamping and pushing-out mechanism are located above the pipe winding forming demolding mechanism. By the adoption of the on-orbit forming device, a regular ultra-long tubular structure stable in mechanical property can be rapidly formed in an on-orbit winding mode and in an ultrasonic welding mode, and the on-orbit forming device can be used for continuously building a space truss and other large space structures subsequently.

Description

technical field [0001] The invention relates to the related technical field of space structure construction and molding, in particular to an on-rail forming device for space structure rods. Background technique [0002] The development mode of the existing spacecraft is ground manufacturing, and the rocket is launched and assembled after being carried to the orbit. Due to the limitation of the launch vehicle and technical level, it is very difficult to construct space large-scale facilities such as space solar cell arrays, space large-scale antennas, and space platforms. It is even technically unrealizable, so the construction of large-scale space structures in orbit is a disruptive technology that changes the size and carrying constraints of future spacecraft. In the existing research, based on thermoplastic composite material strips as raw materials, rods and space trusses are processed by means of heat source heating and pultrusion, and large-scale truss structures on the...
