某重型卡车格栅防虫网的优化设计

Optimization Design of Grille Insect-proof Net for a Heavy Truck

防虫网是保护水箱和冷凝器的重要零部件,文章所述防虫网是装配在格栅内侧的金属防虫网。为了解决防虫网脱落、装配不平整等问题,文章对国内外多种车型防虫网安装方式进行对比,经过样件试验和样车装配,再结合样件的结构特点、生产装配周期、成本等因素最终确定了热熔焊连接方式为当下最优的安装方式,并与螺钉固定防虫网方案进行具体的性能对比,总结出热熔焊方案的优缺点,再通过技术优化,采用挡板和压条以及热熔点的合理布局等方案解决了漏胶和不服帖的问题。

Insect-proof net is an important part to protect the water tank and condenser.The insect-proof net described in this paper is a metal insect-proof net assembled in the inside of the grille.In order to solve the problems of insect-proof net falling off and uneven assembly,this paper compares the installation methods of insect-proof net for a variety of domestic and foreign models.After sample test and assembly of sample vehicles,combined with the structural characteristics,production and assembly cycle,cost and other factors of sample parts,the hot melt welding connection method is finally determined as the optimal installation method at present,and the specific performance of the screw fixed insect-proof net scheme is compared.The advantages and disadvantages of the hot melt welding scheme are summarized,and the problems of glue leakage and adhesion are solved by using baffle and laminate and reasonable layout of hot melting point through technical optimization.
