我厂生产的厨房设备中,如电灶、油灶、汤锅、蒸汽锅等都使用了各种大尺寸不锈铜球形锅底,因此大球形不锈钢零件的拉伸在我厂就是一个突出的问题。十多年来的实践,我们在大球形不锈钢零件的拉伸模设计中积累了一些经验。下面介绍两种拉伸模的设计。 一、采用双压延梗的凹模 虽然拉伸球形(半球形)零件时,它的拉伸系数是个常数(m=d/D毛=d2~(1/2)~(d2)
I plant the production of kitchen equipment, such as electric stove, oil stove, soup pot, steam pot and so use a variety of large-size stainless steel spherical pot bottom, so large spherical stainless steel parts stretching in our plant is a prominent issue . More than a decade of practice, we have accumulated some experience in the design of drawing dies for large spherical stainless steel parts. Here are two kinds of drawing die design. First, the use of double calendared stem concave Although the spherical (hemispherical) parts, its tensile coefficient is a constant (m = d / D hair = d2 ~ (1/2) ~ (d2)
