圆筒形零件引伸是板料冷引伸中最简单又具代表性的一种,其工艺计算方法在引伸工艺中有其代表性,和其它如匣形件、锥形件及其它复杂形状零件的引伸工艺计算都有其共同所在。因此,正确掌握和运用圆筒形零件引伸时的变形特点和工艺计算方法,对了解和掌握不同形状零件在特定条件下的引伸极其重要。 圆筒形零件引伸,所使用毛坯料为圆形,坯料在引伸过程中的变形和应力状态是众所周知的(图1)这种变形的范围用引伸
Cylindrical part extensions are the simplest and most representative of cold extrusions of sheets, and their process calculation methods are representative in the drawing process, as are other parts such as box, conical and other complex shapes Extension process calculation has its common ground. Therefore, it is extremely important to understand and grasp the extension of different shape parts under certain conditions when correctly understanding and applying the deformation characteristics and the process calculation method when the cylindrical parts are extended. The extension of the cylindrical part, the blank used is circular, the deformation and stress state of the blank in the extension process is well known (Figure 1) The scope of this deformation with the extension
