提出了计算任意形状的杯形压延件毛料外径的通式,免除了计算弧线重心的困难。在冲裁压力中心的计算中,还可以利用通式计算弧线重心。文章还给出了利用简化公式和查线图求杯形毛料半径的方法。
The general formula for calculating the outer diameter of the cup-shaped calender with arbitrary shape is proposed, which avoids the difficulty of calculating the center of gravity of the arc. In the calculation of blanking pressure center, you can also use the general formula to calculate the arc center of gravity. The article also gives the method of calculating the radius of cup-shaped wool using the simplified formula and the look-up graph.
