The invention discloses a lifting hook group for shot blasting treatment and a preparation method. The lifting hook group comprises a pair of connecting rods, transverse rods, a connecting plate, gaskets, nuts and a lifting hook, the multiple transverse rods are evenly arranged between the connecting rods, the lower ends of the connecting rods are fixedly installed on the connecting plate through the gaskets and the nuts 5, the lifting hook is fixed to the center position of the connecting plate, the diameter or the number of the transverse rods and the thread diameter of each connecting rod are increased, transition arcs are added at the steps of the connecting rods, the connecting rods are subjected to heat treatment, and the mechanical property is improved; and rubber gaskets are additionally arranged between the connecting plate and the connecting rods. The stress distribution condition of the weak part is analyzed by adopting a finite element analysis method, and the diameter or number of the transverse rods is optimized and the thread diameter of each connecting rod is increased until the strength requirement is met.
一种喷丸处理用吊钩组及制备方法,包括一对连接杆、横杆、连接板、垫片、螺母和吊钩,连接杆之间均匀设置若干个横杆,连接杆的下端通过垫片和螺母5固定连接板安装,连接板的中心位置固定吊钩,增大横杆直径或数量及连接杆螺纹直径,在连接杆台阶处增加过渡圆弧,并对连接杆进行热处理,提高机械性能;再在联接板与连接杆之间增加橡胶垫片。采用有限元分析的方法分析其薄弱部位的应力分布情况,并经优化横杆直径或数量和增大连接杆螺纹直径直到满足强度要求为止。
