Abstract
The invention relates to a bending die and a bending method of a pentagonal cabinet shell, and aims to solve the problem that the bending technology of an existing cabinet shell is complicated, low in production efficiency and high in rejection rate and needs various dies. The bending die comprises a first stamping die, a first gasket iron, a second stamping die and a second gasket iron. The bending method includes the steps: placing a plate at the upper end of a first stamping groove; stamping the plate by the aid of the first stamping die; bending the plate of a third bending section downwards to form a fourth bending section; placing the bent plate in a second stamping groove after the bent plate is rotated by 180 degrees by taking a horizontal line as an axis; stamping the second stamping die towards a second bottom edge along a third vertical surface to form a fifth bending section; bending the fifth bending section towards a second side face and an upper inclined plane of the second stamping die. The bending die is simple in technology and high in finished product ratio.
