|
|
The article introduces the concept, characteristics,main technical limitation of the narrowing-mouth process and affecting factors of deformation degree,analyses the manufacturability of the double-ended spherical-top parts process and confirms to use the shrinkage cavity technology to finish the production of the part by comparison.On this,the article makes a detail introduction in the aspects of content and process about the narrowing-mouth process of the given parts,provides the procedure sequence, deformation degree of every procedure,the height of the billet and the part size of every procedure and introduces the selecting methods of the press.Integrated with the trial-produce of the part,the article discusses the structure design,the operating principle,the interrelation and functions of the main parts of the die.The analysis of the test-piece quality shows that the result of the narrowing-mouth process and the die structure design can meet the processing technical requirements of the given parts,and the test-piece can completely meet the design requirements.At last,the article points out the process impact brought by deformation,which is often ignored in the narrowing-mouth process and the further research for improving this problem.
