对J型加筋壁板共胶接技术在实际应用中所存在的主要问题进行了研究,着重介绍了R区芯材精确填充、筋条外型模成型、框架式插销垂直定位、共胶接真空袋封装等关键技术的研究情况,并对相关技术的应用进行了深入分析。研究结果表明,在精确计算的基础上,设计制造专用成型模具可实现R区填充芯材的精确制备,有利于提高加筋壁板胶接质量;选用筋条外型模成型工艺,并设计采用框架式插销垂直定位装置,可有效解决J型筋的表面成型质量、筋条尺寸精度、位置精度等问题;使用已硫化橡胶作为维形挡条、制备合适的内型面软模、优化辅助材料铺放方法,可减少表面质量问题,降低架桥、破袋风险。在应用了上述一系列制造技术后,成功制造了满足使用要求的J型加筋壁板复材零件,并初步实现该类型零件的批量化生产。
The main problems existing in the practical application of J-type stiffened wallboard are studied, with emphasis on the precise filling of R core, the external shape of ribs, the vertical positioning of frame bolt, Vacuum bag packaging and other key technologies research situation, and the application of related technologies in-depth analysis. The results show that, on the basis of accurate calculation, it is feasible to design and manufacture special molding die to precisely fabricate the R-zone filled core material and to improve the quality of the reinforced wall panel bonding. The vertical positioning device of the frame bolt can effectively solve the problems of surface forming quality, rib size precision and position accuracy of the J-shaped rib, and uses the vulcanized rubber as a profile bar to prepare a suitable soft mold with an inner surface and optimize the auxiliary material shop Put the method can reduce the surface quality problems and reduce the risk of bridging, breaking the bag. After applying a series of manufacturing technologies mentioned above, the J-type reinforced siding composite parts that meet the operating requirements have been successfully manufactured and the mass production of such parts has been initially achieved.
