Design LQ200 CNC Machine Spline Knocked Cold

Large modulus spline can withstand heavy loads, which is widely used intransmission systems, particularly mechanical, electrical, automotive, marine,aviation, aerospace，defense and other heavy machinery industry, so largemodulus spline has an increasing demand, due to the large modulus splinesrequire to be able to withstand heavy loads, the spline surface must be highquality. Conventional spline processing methods are mainly cutting, but thisprocessing method bring down the spline surface quality and processingefficiency and cut out the metal fiber breakage. In recent years, because of morehigher Forming accuracy of cold bulk metal forming. researchers pay more andmore attention to this forming technology, for large spline modulus processing,the deep alveolar molding requires higher energy processing, cold rolling andcold rub machining requires relatively large motor power and rack rigidity toform large modulus spline, which is also serious to the machine stiffness andmaterials. The spline cold knocked machine solves this problem, which relys onthe theory of spline cold roll rotational torque, it has high energy conversionefficiency. For this reason, the research equipment and processes of coldknocked spline is studied by Qingdao sheng jian factory with the TaiyuanUniversity of Science and technology. And they developed a LQ-200CNC splinecold knocked machine.In this paper, the model of the key components was made by thethree-dimensional design of ug software, in accordance with the requirementsassembly of cold knocked machine, cold knocked machine were assembled withthe parts, then the cabinet stress analysis model that was established to make themodal analysis and static analysis, in order to reduce processing errors causedby the deformation, deformation larger area need to increases the ribs thickness,and large deformation topology optimization ribs were obtained by analyzingthe size of the rib parameters, the optimized structure of the gunda wheel wasdesigned to obtain the structural parameters, all improvements Parameters ofCNC spline cold knocked machine have important guiding significance. The assembled CNC spline made the foundation of Stability and transmissiondynamics anasys of the machine, the research guided use of cold knockedforming machine. The research promote the application of CNC spline coldknocked machine.
