我厂设计制造的9m~3铲运机,必须自制轮辋。由于轮辋直径较大(φ760mm和φ634mm两种),板厚12mm,加工困难。经过分析,我们自制热压模具,一次压辋成形轮辋,质量好,达到设计要求,在京秦线铁路施工中使用情况良好。一、工艺分析9m~3铲运机轮辋如图1所示。1.这种直径大、壁厚的热压件,拉延变形抗力很大。为了获得较小圆角半径与较准确 I plant design and manufacture of 9m ~ 3 scraper, you must make your own rims. As the larger rim diameter (φ760mm and φ634mm two), thickness 12mm, processing difficulties. After analysis, we made a hot pressing mold, a rims forming rims, good quality, meet the design requirements, the use of the railway line in Beijing-Qinhuangdao good. First, process analysis 9m ~ 3 scraper rim shown in Figure 1. 1. This large diameter, thickness of the hot-pressing pieces, draw large deformation resistance. In order to obtain a smaller fillet radius and more accurate
