设计生产球形拉延件(如蒸汽机车上的汽包、砂包等)的深拉延模,比浅拉延模困难得多。原因是这类零件的表面形状比较复杂,拉延过程中的受力情况、变形区的位置,变形特点及其成形原理与一般的浅拉延模生产的零件不同。一、球形拉延件的工艺特点球形件的拉深与浅筒形件的拉深相比,有下述不同之处。 1.受力情况图1表示了球形件和浅筒件拉深时主变形区的受力分析,比较如下。

Design and production of spherical drawing parts (such as steam locomotive drums, sandbags, etc.) of the deep drawing die, drawing than the shallow drawing much more difficult. The reason is that the surface shape of such parts is more complex, the drawing force in the drawing process, the location of the deformation zone, the deformation characteristics and the forming principle are different from those produced by ordinary shallow drawing die. First, the process characteristics of the spherical drawing parts The drawing of the spherical parts compared with the drawing of the shallow cylindrical parts, the following differences. 1. Force situation Figure 1 shows the spherical member and the shallow cylinder deep drawing deformation analysis of the main deformation area, compared as follows.
