Abstract
This design is based on the need of KaSun Co., Ltd. of Zhejiang, in order to achieve large-diameter seamless steel pipe to meet the requirements of drawing-reducing technology, according to the actual production conditions and reducing the existing Drawing on the basis of the proposed Drawing by a trail of the transformation of design options. In this design, changed the design to complete their previous experience with the design of the important components and an important motor of the design options put forward a theoretical basis. Among them, in the process of drawing the control, according to pull air pipe mechanical performance requirements, a number of the necessary calculations in the cooling lubrication system has also done a significant improvement, achieved good results. At the same time, according to the customer on the products of the technical parameters of indicators, a number of important parts of the structure and design calculations. Upon completion of the design, manufacture a the whole machine assembly, the whole machine a performance test to meet the Zhejiang KaSun Co., Ltd. put the technological requirements, scheduled to meet design objectives.
