Research and Design on the Special Tube Parts Stamping Technology and Die
This paper introduces the concept and characteristic of narrowing-mouth process,and the main technological defects and the influence factors of narrowing-mouth deformation degree.Processing technology of double closed ball head tube parts was analyzed and narrowing-mouth process was used to manufacture.On this basis,the content and steps for mouth process calculation were introduced detailed.The number of narrowing-mouth process,deformation degree of every process,the height of the blank and the size of parts were given.Meanwhile the press machine was selected.Combined with parts trial,the narrowing-mouth die structure was designed a detailed discussion of the work principle of the die,relationship and function of main parts of die were done.Through analysis of the specimen quality,the results explain that the narrowing-mouth technical calculation and die design can satisfy the processing technology of all the given parts.It can basically meet the design requirements.Finally the influence on narrowing-mouth process of neglected deformation and further research to improve it are pointed out.
