| Abstract: | In order to improve the shaping design ability of students in mechanical drawing,it is necessary to introduce and analyze the shaping design of parts and some typical shaping method.Firstly,shaping designs of different structures of some parts such as installation part,connection part and so on are introduced,and then the shaping design procedure of the base of reducer is analyzed.Secondly,some typical shaping design methods such as shaping design based on the deformation of the basic body,profile design shaping design,complementary shaping design,equal volume shaping design,variation shaping design and combinatorial shaping design are introduced and analyzed.Finally,the design model of various pipe joints used in the exhibition hall is given as a design question.It will be helpful to improve the spatial imagination and shaping ability of students. |
