CAD Application on Manufacture of Forming Shoulder for Packaging Machines
Based on the theoretical analysis of forming shoulder used in fill-and-seal packaging machine, this paper presented the 2-D and 3-D mathematical models of offset bending curve jointing the vertical tube and shoulder parts. According to the technology widely used in the manufacturers, the theoretical basis was provided for preparing the rough parts to make the shoulders. Furthermore, a new method using test tube was proposed to check the shape curve and locate the shoulder parts before welding. Transformed from 3-D offset bending curve, the 2-D cutting data of test tube was also provided for practical use.
