在生产中,我们经常碰到如图1所示的通风板零件。不同的零件,风窗长短也不同。为了减少模具的制造成本,我们用一个凹模(图2)和不同规格的凸模(图3)实现了多规格的风窗冲压成型。图3中l_1为风窗要求的长度,l_2一般为40毫米,l=l_1+2l_2,h_1为风窗的深度,h=h_1+40毫米,b为凸模的

In production, we often encounter as shown in Figure 1, the ventilation plate parts. Different parts, the window length is also different. In order to reduce the manufacturing cost of the molds, we achieved the multi-specification window stamping with one die (Figure 2) and different sizes of punch (Figure 3). L_1 is the required length of the windshield in Figure 3, l_2 is generally 40 mm, l = l_1 + 2l_2, h_1 is the depth of the windshield, h = h_1 + 40 mm, b is the
