各种金属板材的旋压成型在工业上已得到广泛的应用,在日用器皿的生产中应用也很广,但有关这方面的资料很少,现简单介绍如下: 旋压工艺就其方式可分为外旋(缩口)、内旋(涨型)和内外旋(挤压成型)。内旋和外旋又可分为有芯模和无芯模两种。旋压用的设备也可分为两种:1.专用旋压机,2.用普通车床改制的旋压机,在日用铝制品厂中后者使用较多。 日用器皿旋压成型的典型模具见图1,
Spinning and forming of various sheet metal has been widely used in industry. It is also widely used in the production of household utensils. However, little information is available on this subject. The brief introduction is as follows: Divided into external rotation (necking), internal rotation (up) and internal and external rotation (extrusion). Internal rotation and external rotation can be divided into a core mode and coreless mode two. Spinning equipment can also be divided into two types: 1. Spinning machine, 2. Spinning machine with ordinary lathe, in the daily use of aluminum products factory in the latter use more. The typical mold for the spinning of household utensils is shown in Figure 1,
