Spinning processing technology is a commonly used metal forming processing method, the use of CNC machine tools to rotate metal billet processing. It has the advantages of high processing efficiency, high processing precision and good surface quality, and is widely used in the manufacturing field. 2, spinning open material size calculation method
1. Diameter calculation Spinning open material diameter calculation is divided into inner diameter and outer diameter two cases.
(1) Inner diameter calculation formula: diameter = turning radius – plate thickness ×1.57.
(2) Outer diameter calculation formula: diameter = radius of rotation + plate thickness ×1.57, where the radius of rotation refers to the spinning machine fixed axis (punching) to the center axis of the workpiece distance.
2. Height calculation The height calculation formula of spinning open material is height = plate thickness ×1.5. It should be noted that the change of plate thickness should be taken into account when height calculation, and the value of the thinnest plate thickness is usually taken as the calculation basis.
3. Countersunk head calculation Countersunk head refers to the degree of inward depression at the bottom of the spinning open hole, and is also an important parameter of the spinning open hole. The formula for calculating countersink is countersink = plate thickness +3. It should be noted that the size of the countersink is related to the hardness of the plate, and it needs to be fine-tuned in actual processing.
