Apparatus and method for forming large-size winding composite material ring

Abstract

The invention discloses a molding device of a large-size winding composite material ring. The molding device comprises a winding molding module with a whole shaft and two end seals, and is characterized in that detachable annular yarn stop modules are mounted on the outer sides of the two end seals of the winding molding module; and the annular yarn stop modules are coaxially arranged with the winding molding module, and outwards extend from the seal yarn falling positions of the winding molding module in the axial direction to prevent slippage of yarns in the seal yarn falling positions of the winding molding module. The molding device can effectively prevent slippage of the yarns in the seal yarn falling positions in the winding process, is high in winding stability and efficiency, and improves the preparation stability and the preparation efficiency of the large-size winding composite material ring with the yarns of 40-50 o. The invention further provides a molding method of the large-size winding composite material ring.

Description

Technical field [0001] The invention relates to a forming device and method for a large-size winding composite material ring, belonging to the technical field of winding forming technology. Background technique [0002] The development of high-efficiency traction transformers is an important way to increase the speed of EMUs and improve the efficiency of traction and environmental adaptability. At present, domestic traction transformers are large in size, weight, and low electrical efficiency. Superconducting transformers have strong current carrying capacity, high electromagnetic density, and no DC resistance. The volume and weight can be reduced by 30% to 40% under the same power. The efficiency is up to 99% or more, and it can withstand large overloads, is insensitive to changes in external ambient temperature, and is easy to obtain large short-circuit impedance without affecting electrical efficiency. The support ring is an important part of the superconducting magnet of the...

[0006] 2. CN 102825798 A, a vertical wet winding device, which relates to a winding forming device for container products, to solve the problem of existing horizontal winding machines or gantry-type winding machines used for winding and forming glass fiber reinforced plastic spheres, spherical tanks and other container products. The winding machine has the problems of slow winding speed, low production efficiency, and is not suitable for mass industrial production. It includes a main shaft drive system, an arm winding mechanism, a rotating bracket, a rubber dipping mechanism, and a swinging yarn output mechanism; the arm winding mechanism includes arm beams, Flange, shaft sleeve, second bevel gear, first shaft support, sleeve shaft, second shaft support, sliding shaft, sliding shaft support, third bevel gear, support shaft, turntable, sliding bearing seat , the fourth bevel gear, the first screw nut, the screw, the second screw nut, the balance weight body and two screw supports, the turntable is connected to the rotating bracket; the dipping roller is located between the two dipping roller support blocks, And the dipping roller is rotatably connected with the two dipping roller support blocks

[0009] Some of the above-mentioned winding forming devices or methods prevent thread slippage by changing the winding angle, some prevent thread slippage by changing the winding process to make the resin matrix layer gel, and some prevent yarn loosening or Sliding thread, but since the surface of the head of the winding forming device is an ellipsoid, none of these solutions can prevent the yarn from slipping along the ellipsoid at the drop line of the head, and the greater the thickness of the winding, the possibility of slipping The higher the yarn is, the reliability of preventing slippage needs to be improved. A yarn winding forming device can be designed to effectively prevent the yarn from slipping on the head during the winding process, and the yarn can be increased to 40-50 o The preparation stability and preparation efficiency of the large-scale winding composite ring are the object of the present invention
