一、概述 我厂系单件小批多品种纺机生产厂,每年生产的产品有80多个品种,仅冲压件有一万多个零件,零件的特点是板料厚(1.5～10毫米)尺寸大(长度在1000毫米左右),这类零件用一般的薄板模,橡皮模,或小型组合模,均不适应需要。我们对冲裁件进行了基素分析,工件几何图形基本是由直线,圆角,圆头,缺口和大小不同的各种孔型(圆孔,方孔,长圆孔,长方孔)所组成,如图1。
I. Overview I plant a small batch of more than one species of textile machinery manufacturer, the annual production of more than 80 varieties of products, only stamping parts have more than 10,000 parts, the characteristics of parts is sheet metal thickness (1.5 ~ 10 mm) Large size (length of about 1000 mm), such parts with a general sheet metal mold, rubber mold, or small modular, are not adapted to the needs. We carry out the analysis of hedging elements, the workpiece geometry is basically composed of a variety of hole patterns (round holes, square holes, oblong holes, rectangular holes) with different straight lines, rounded corners, round heads, notches and sizes, Figure 1.
