斜楔式轮辐侧孔冲模设计

Design of the Sideling Wedge Die of the Side Hole in Spoke Disc

以微型汽车上的轮辐侧壁长孔冲裁斜楔模为例,介绍了模具的结构尺寸和工作原理,对模具设计要点进行了简要论述。

Bearing force analysis and efficiency calculation of the sideling wedge mechanism have been carried out.The phenomenon of self lock because of the friction function and preventive measures have been ecpounded.Deter-mining principle of the main parameters of the sideling wedge die in design has been given with an instance of such die for punching six long holes of12×4.00B in side wall of spoke disc of minicar,with description of the structure size method,work principle and the die design main points.It may be valued in reference for the die design of the same kind parts.
