对预应力碳纤维缠绕制造重型压机机架进行了研究,选用碳纤维(T700SC-12000)和钛合金(TC11)框架作为预应力结构的部件,把全新的材料应用到了25 MN模锻压机机架主要部件的设计中,进行了碳纤维缠绕机架的结构设计,依据输入的设计参数,建立了压机机架的模型,同时也对25 MN模锻压机进行了A型变张力缠绕设计,并对设计之后的结构进行了有限元分析。结果表明,应用预应力碳纤维缠绕技术极大地提高了预紧力对重型压机的梁和柱的保护,增加了零件的可靠性,并降低了大型零部件的制造风险,预应力碳纤维缠绕制造的重型压机机架强度设计满足要求,机架在预紧状态下的等效应力为863.9 MPa,小于钛合金TC11的屈服强度,而且减重效果明显,压机机架的质量从8 022kg下降到了1 950.76kg,下降了75.7%。
The research on the prestressing carbon fiber winding manufacture of heavy duty press racks was made. Carbon fiber (T700SC-12000) and titanium alloy (TC11) frames were selected as the components of the prestressed structure. The new materials were applied to the main parts of 25 MN forging press racks In the part design, the structure design of the carbon fiber winding frame was carried out. According to the input design parameters, the model of the press frame was established. At the same time, the A-type variable tension winding design of the 25 MN die-forging press was also carried out. After the structure of the finite element analysis. The results show that the application of prestressed carbon fiber winding technology can greatly improve the preload on the heavy-duty beam and column protection, increase the reliability of the parts, and reduce the risk of manufacturing large parts, prestressed carbon fiber wound heavy pressure Machine frame design to meet the requirements of strength, frame preload in the equivalent stress of 863.9 MPa, less than the yield strength of titanium alloy TC11, and weight loss significantly, the quality of the press rack from 8 022kg down to 1 950.76 kg, a decrease of 75.7%.
