本装置能将扇形金属薄板弯曲成截头圆锥筒形零件,具有成型容易、生产效率高等的优点,适应大批量生产。扇形金属薄板两端的弧长应按一定的比例,长边在高速滚轮端,短边在低速滚轮端。材料在两端速度不同的滚轮中转动,弯曲成圆锥体。以下按图对本装置加以说明。设扇形金属薄板两端的弧长比为5:1,那么低速滚轮与高速滚轮的转速比应为1:5。圆锥体的弯曲要调节弯曲滚轮。右视图表示的是调节螺杆机构,
The device can bend the fan-shaped metal sheet into a frusto-conical cylindrical part, has the advantages of easy forming and high production efficiency, and is suitable for mass production. The arc length at both ends of the fan-shaped metal sheet should be at a certain ratio. The long edge is on the high-speed roller end and the short edge is on the low-speed roller end. The material is rotated in rollers of different speeds at both ends and is bent into a cone. The following figure by the device to illustrate. Let arc-length ratio at both ends of the fan-shaped metal sheet is 5: 1, then the speed ratio of low-speed roller and high-speed roller should be 1: 5. Bending of the cone To adjust the bending roller. Right view shows the adjustment screw mechanism,
