Embodiment

[0019] Such as figure 1 As shown, a method for laying the core material of wind power blades specifically includes the following steps:

[0020] A. Cut and splice the core material 2 into a whole that fits the size of the mold 1;

[0021] B. The surface of the mold 1 is covered with fabric, and a layer of plastic film is laid on the fabric;

[0022] C, placing the core material 2 on the plastic film at a loose position in the mold 1;

[0023] D. Pull the plastic film to drive the core material 2 to move from the loose position of the mold 1 to the preset position.

[0024] In step D, when the plastic film is pulled to move together with the core material 2, the core material 2 is manually pushed and matched at a constant speed until the core material 3 is moved to a preset position. At this time, due to the action of a layer of plastic film between the fabric on the surface of the core material 2 and the mold 1, the friction between the outer surface of the core material 2 ...

Abstract

The invention discloses a laying method for wind turbine blade core materials. The laying method comprises the following steps of laying a layer of plastic films on fabric, putting the core materials on the plastic films at loose positions in a mould, pulling the plastic films, and driving the core materials to move to preset positions from the loose positions of the mould. The laying method effectively solves the problems that in a core material laying method in the prior art, the core materials are damaged, wrinkles and damages are caused on the surfaces of the core materials and fabric on the surface of the mould. The method is reliable in implementation process, is clear in process, and greatly improves production quality.

Description

technical field [0001] The invention relates to the field of production equipment, in particular to a method for laying core materials of wind power blades. Background technique [0002] China is a country that is short of energy. The development of new energy, especially the application of core technologies with China's independent intellectual property rights, and the vigorous development of wind power have become one of the main strategies of China's energy. From the perspective of the structure of the wind blade, it includes the skeleton and core material. At present, the sandwich materials used for composite sandwich structures mainly include three types: rigid foam, honeycomb and balsa wood. Especially with the rise of the world's renewable energy wind power industry, the value of the structural foam core material of the main material of wind energy blades has been greatly increased. During the manufacturing process of wind blades, the core material needs to be cut in...
