The last set is also bending die casting die for bending two sides.
From aspect of applicability of single thin-wall tube bending measures in tube panel bending, panel bending procedure using cylinder bending die for water wall is discussed.
The symmetric wire bent elements of small-production and low-accuracy used the simplerevolving bending die to improve economical efficiency.
From the angle of bending die structure design, the methods and skills of reducing springback in production are expounded.
