圆角半径
radius of rounded angle
- 文摘:介绍形成小圆角半径的圆孔翻边模具的结构特点，按体积不变的原则，推导了计算公式。
Abstract: Die structure based on the process of forming small fillet radius is introduced,and deduced the formula according to the principle of volume invariably. - 回弹角随凸模圆角半径和凸凹模间隙的增大而增大，随压边力、板料厚度、摩擦系数和材料硬化指数的增大而减小。
The springback angle increases with the increase of the punch round radius and clearances between the punch and the die while decreases with increase of the blank holder force, sheet thickness, friction coefficient and material hardening exponent. - 通过模拟计算可知，提高喷射压差和减小喷孔入口圆角半径都可以提高空穴强度，同时也发现提高喷孔长径比可以使空穴在喷孔出口截面上分布更为均匀。
Simulation results show that better atomization can be realized by enhancing the cavitation intensity via increasing the injection pressure difference or decreasing the nozzle inlet round angle-radius ratio.
