制作油桶的油桶板两纵边的直线度直接影响油桶质量。我厂1200薄板轧机叠轧的油桶板规格为1800×930mm。用一台圆盘剪同时剪切板的两纵边,往往被切成同方向的两条弧线(镰刀弯)而造成废品。圆弧的允许弦高范围就是控制指标。 一组刀片的剪切情况如图1。设上下刀片的角速度为ω,刀片直径为D,上下两刀片的重叠量为δ;交点A处的水平速度v_A我们视为圆盘剪的剪切速度;
The straightness of the two longitudinal edges of the drum plate making the oil drum directly affects the quality of the oil drum. I plant 1200 sheet metal rolling mill drum plate specifications 1800 × 930mm. With a disc shears at the same time cut the two longitudinal edges of the board, tend to be cut into two arcs (sickle bend) in the same direction and cause waste. Arc allows the chord height range is the control indicator. A group of blade cutting situation shown in Figure 1. Set the upper and lower blade angular velocity of ω, the blade diameter D, the amount of overlap between the upper and lower blade is δ; intersection point A at the horizontal speed v_A we see the disc shearing speed;
