Embodiment 1
[0028] combine Figure 4 to Figure 8 To illustrate the specific implementation of this patent.
[0029] Load-bearing travel wheels 13 are set below the laying trolley, and walking guide wheels 14 are set outside the laying trolley, and contact and spacing are carried out between the laying trolley and the track by the load-bearing traveling wheels 14 and the walking guide wheels 14.
[0030] Servomotor 16 is arranged below the trolley, and the servomotors below it are relatively fixed, and a gear is arranged at the shaft end of the servomotor, which meshes with the rack on the track, and the operation of the servomotor is controlled by a computer program.
[0031] Rails 18 parallel to the axis of the mold are arranged below the mold, wherein one track is a rack structure, and the upper surface of the track is kept parallel to the axis of the mold when the upper surface of the track is fixed with the mold. The servo motor drives the laying trolley to move along the track paral...

The invention provides a technology for automatically laying shaping a composite material crossbeam. When the composite material crossbeam is produced, a servo motor is started under the control of a program controller to drive the motor to rotate, so as to drive a car to reciprocate along rails; when the car runs, laying wheels lay fiber cloth on the surface of a crossbeam mold so as to automatically lay the fiber cloth during the process of producing the composite material beam; after laying, a vacuum flow guiding system is established on the surface of the crossbeam mold; and the resin is filled into a laying layer of the fiber cloth, after the resin is soaked, the resin is completely cured to demold so as to obtain the product. Through the method provided by the invention, the labor intensity of workers can be reduced; the production efficiency and product quality can be improved; and the composite material shaping technology is converted to automatic laying production from manual laying production.
Description
technical field [0001] The invention relates to a composite material girder forming technology, in particular to an automatic forming method for a composite material girder. Background technique [0002] At present, when the composite girder of wind power blades is manufactured, the laying process of fiber cloth is manual operation. By manually pulling the fiber cloth, the fiber cloth is laid layer by layer on the forming mold of the composite beam, and then smoothed by hand, which takes about 4 to 5 hours. This molding method is labor-intensive and time-consuming. According to a rough estimate of the composite material beam length of 40 meters and 60 layers of fiber cloth, the operator needs to walk at least 4,800 meters to complete the entire layup. Moreover, it is unlikely that the efficiency of manual operation will be improved. If the efficiency is improved by increasing the operating speed by manpower, the quality of the layup cannot be guaranteed. At the same time,...
