Technical Field

The invention belongs to the technical field of mechanical design and manufacturing, and particularly relates to linkage numerical control laying and winding integrated forming equipment.

Background

The traditional numerical control winding machine can complete the winding forming of the composite material skin of a cylindrical, conical and power curve-shaped revolving body, but cannot complete the laying forming of the special-shaped curved surface skin. For the special-shaped curved surface skin, the traditional numerical control cloth belt winding machine is only used for completing the rotation of the mold and the fixation of the prepreg tape, the laying and forming of the cloth belt are completed manually, the prepreg tape applies tension manually in the laying process, and the sticking between the cloth belt and the mold product is not real and is larger than the theoretical circumference.

Except that the revolving body shell type composite material thin-wall skin structural part product can be directly wound and formed by a cloth tape winding machine, the forming of the composite material thin-wall product with the complex space and the special-shaped curve type does not have automatic equipment at present, and the product needs to be formed by hands. The laying direction, precision and laying quality of the composite material skin fibers have great influence on the comprehensive performance and quality consistency of the product. The manual laying firstly needs to preheat the die, so that the prepreg can be well adhered to the die; the laying angle and the gap splicing of the prepreg tows are manually controlled; in order to ensure good adhesion between the prepregs, each 2-3 layers of prepregs are laid, vacuum packaging is needed for carrying out one-time prepressing; the mould needs to be preheated before the next laying, and the prepreg laid on the mould needs to be subjected to a plurality of heating processes frequently. The forming process has long period, high labor intensity and low efficiency; and the fiber laying angle, the splicing seams among fiber bundles, the resin content of prepreg, the fiber straightening degree and the like of the manually-formed composite material structural part cannot be ensured, the product quality stability is poor, and the requirements of engineering high-efficiency production rhythm of composite material space curved surface skin products cannot be met.

Therefore, the fiber mesh cloth is manually used for parallel overlapping winding, oblique overlapping winding of the twill cloth, forming and curing, and then machining and shaping are carried out, and the main defects of the method are as follows:

firstly, after manual curing molding processing, various quality defects such as wrinkles, bridges, layering, cracking and the like exist, so that the product quality reliability, stability and consistency are poor; secondly, the material cost is high due to low material utilization rate, in order to reduce the manual operation difficulty and improve the manual efficiency, the traditional curing process is to directly wrap the whole special-shaped curved surface workpiece, large-area materials need to be cut off after curing to realize molding, the material utilization rate of actual winding molding is less than 30%, and the waste is extremely serious; in addition, redundant cloth tape skin needs to be removed through mechanical cutting, the cloth tape fiber is cut off and damaged in the process, the comprehensive performance is low, the processing cost is high, the dust pollution is serious during cutting, the process turnover period is long, the overall cost is high, and the period is long.
