精密连续模的导正销决定了步距精度,并限制了条料的蛇形送进偏差。为此,对导正销的工作直径尺寸及其数量应有严格要求。导正销直径比冲导正孔的凸模直径小0.01~0.015mm。若导正销工作部分的直径等于冲导正孔的凸模直径时,当送料步距有0.005mm的误差时,导正销会使材料翻边。在安全检测装置中使用活动导正销时,如导
Pilot Punches for Precision Continuous Mold Determine Pace Accuracy and Limit Serpentine Feed Deviation of Strips. To this end, the diameter of the guide is the diameter of sales and its number should have strict requirements. Pilot Punches Diameter than Punches the diameter of the punch is small 0.01 ~ 0.015mm. If the diameter of the working portion of the normal guide pin is equal to the diameter of the punch of the positive guide hole, the guide pin will cause the material to flanging when the feeding step has an error of 0.005 mm. When using a pilot operated safety pin in a safety test device
