Embodiment Construction

[0034] Attached Figure 7 Attached Figure 13 To illustrate the specific embodiment of the present invention: a pentagonal cabinet shell bending die, including a first die 1, a first shim 2, a second die 3, and a second shim 4. The first die 1 and the second die A shim 2 is used in conjunction, and the second die 3 is used in conjunction with the second shim 4. The upper end of the first shim 2 is provided with a first punching groove that matches the shape of the lower end of the first punch 1. The first punching groove includes a A vertical surface 2-1, a second vertical surface 2-2 and a first bottom surface 2-3, the first vertical surface 2-1 and the second vertical surface 2-2 are parallel to each other and are both parallel to the first The bottom surface 2-3 is vertical; the upper end of the second shim 4 is provided with a second punching groove matching the shape of the lower end of the second die 3, and the second punching groove includes a third vertical surface 4-1 ...

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.

Description

Technical field [0001] The invention relates to a bending mold of a cabinet shell and a bending method of the cabinet shell, in particular to a bending mold of a pentagonal cabinet shell and a bending method of the pentagonal cabinet shell, belonging to a mold and a mobile type Special processing technology field of cabinet. Background technique [0002] At present, most of the metal cabinets on the domestic market that are easy to move and transport for loading electronic instruments, meters and electronic components are glass fiber reinforced plastics, metal frame type, etc. The disadvantages are bulky, heavy structure, poor seismic performance, and inconvenient recurring Transportation and movement. A metal shell cabinet with reasonable design, simple structure, convenient transportation, and excellent seismic performance came into being. That is, the demand for a shell structure with a closed pentagonal structure on both ends of the cabinet has greatly increased. [0003] In ...
