轿车覆盖件模具设计需要关注的要点有哪些?

轿车覆盖件模具设计对于汽车的设计制作有着重要意义,山东模具制造厂家给大家总结了一下,轿车覆盖件模具设计还必须注意这几个关注点:
The die design of car panel is of great significance to the design and manufacture of automobiles. Shandong die manufacturer has summed up the following points for attention in the die design of car panel:
(1)拉伸件的圆角和直线设计。拉伸件有圆角和直线部分时,在直线部分设置拉伸筋,使进料速度得到平衡;如果在拉伸件直线部分的深度浅的部分设置了拉伸筋,那么深度深的直线部分就不必设置拉伸筋。
(1) Round corner and straight line design of drawing parts. When the drawing part has rounded corners and straight lines, the drawing bars are set in the straight line part to balance the feed speed; if the drawing bars are set in the shallow part of the drawing part, the drawing bars are not necessary in the deep straight line part.
(2)模具内外圈设计。浅拉伸件的圆角和直线部分均应设置拉伸筋,但圆角部分只可设置一条拉伸筋,而直线部分则可设置1-3条拉伸筋;如果有多条拉伸筋时,就应是“外松内紧”,即模具外圈拉伸筋“松”些,而模具内圈拉伸筋“紧”些,这样通过改变拉伸筋高度就能达到这个目的。

(2) Design of inner and outer rings of dies. The round corner and straight line parts of shallow stretching parts should be provided with stretching bars, but only one stretching bars can be set in the round corner part, while 1-3 stretching bars can be set in the straight line part. If there are more stretching bars, it should be "loose" inside, that is, the outer ring stretching bars of the die should be "loose" while the inner ring stretching bars of the die should be "tight" so as to pass through. This can be achieved by changing the height of the tension bar.
(3)拉伸筋轮廓应呈凸凹曲线形状。在凸曲线部分应设置宽度拉伸筋。而在凹曲线部分可以不设置拉伸筋;拉伸筋或者拉伸槛应尽量靠近拉伸筋模圆角,这样可以增加材料利用率和减少模具外廓尺寸,但要考虑不要影响修边模的强度。
(3) The outline of the stretching rib should be convex and concave. Width tension bars should be set in the convex curve part. In the concave curve part, no stretching bar can be set; the stretching bar or the stretching threshold should be as close as possible to the round corner of the stretching bar die, so as to increase the material utilization rate and reduce the size of the die outline, but it should be considered that the strength of trimming die should not be affected.
