复合材料大巴车身模具的设计与制造技术
|
摘要
基于北京玻钢院复合材料有限公司在模具工程化领域的经验,详细阐述了复合材料大巴车身模具的设计和制造过程,并对产品的各项性能进行了测试。该模具在设计和制造过程中采用了与大巴车模具型面相配套的结构和功能设计,如避免模具屈曲变形的刚度加强设计、顶升机构与金属镶块组成的车底模具脱模系统、温度场稳定性控制系统、双真空系统、可滑动型面调节系统等。之后针对制造过程以及测试过程,介绍了相关的关键点和参数。经验证,该模具各项技术测试均满足产品技术要求,符合初始设计目标。
This paper makes a detailed exposition on composite bus-body mould design and manufacture technology by referencing the former experience on engineering. Then the performance testing of mould products was introduced. A variety of structure and function design are used in the process of making the mould,such as stiffness reinforced structure,demolding device consist of lifting mechanism and insert blocks,temperature field stability control system,double vacuum suction system,and sliding surface adjustment system etc. The key points were introduced during manufacturing process,and the testing result of the performance reveal that this mould can meet every technical requirement. Finally,the final service properties can fulfill the requirements of customers well,which verified the feasibility of the design and manufacture technology.
