在薄板毛坯上压制长条形加强筋,既可增加制件结构的刚性,又可增加表面的美观,这在汽车制造行业的零件冲压加工中被广泛地采用,压制半圆形加强筋(如图1所示),则更为普遍。 对压筋凹模的设计,一般有如下两种形式,如图2,相比之下,图2(b)形式有如下优点: The pressing of strip-shaped stiffeners on sheet blanks not only increases the rigidity of the part structure but also increases the appearance of the surface, which is widely adopted in stamping of parts in the automobile manufacturing industry. Pressing of semicircular stiffeners Figure 1), it is more common. The design of the tendon die, generally have the following two forms, as shown in Figure 2, in contrast, Figure 2 (b) form has the following advantages:
