The Plastic Machine Engineering Volume 6 ~ 10 × 1 aluminum extrusion tube when the basic parameters in Table 1, this area of the geometric parameters of plastic deformation were the actual test, and measured and calculated values listed in Table 2, comparative results show that good agreement between the two basic parameters of Table 1, the project fills the length Si Squeeze the length Si Yi maximum width of a cavity gap of more than h ', ramJUnmJtmmJnT1mj6 conclusion tank rounds are established formula for calculating the contact stress, on this basis, determine the length of the filling, squeeze over the length and width of overflow, geometrical parameters for the round groove design provides a theoretical basis.
