Forming device for sheet metal cabinet

Abstract

The invention discloses a forming device for a metal plate cabinet, and particularly relates to the technical field of metal plate cabinet forming, the forming device comprises a forming chamber, one side of the forming chamber is connected with an inlet cavity, three outer shaping plates are fixedly mounted in an inner cavity of the forming chamber, and a metal plate is arranged in the inlet cavity; an inner shaping plate is arranged on the inner side of each outer shaping plate; according to the metal plate bending device, the three outer shaping plates and the inner shaping plate are bent for multiple times, chamfering transition is carried out on the bending section of a metal plate under the cooperation of the chamfering faces, the sharp phenomenon is avoided when the metal plate is bent, the bending section of the inner shaping plate is pushed through the pushing air cylinder, the reset phenomenon is avoided in the bending process of the metal plate, and the bending efficiency of the metal plate is improved. The forming quality of the metal plate cabinet is improved, the metal plate cabinet can be suitable for bending forming of metal plates with different thicknesses, one end of each metal plate makes contact with the corresponding chamfering face and is bent upwards, and the leveling pressing plate is used for bending the cut metal plates.

Description

technical field [0001] The invention relates to the technical field of forming sheet metal cabinets, in particular to a forming device for sheet metal cabinets. Background technique [0002] Sheet metal cabinets are generally made of cold-rolled steel plates or alloys. There are generally two methods for forming sheet metal cabinets. One is the patchwork of sheet metal, and the sheet metal panels are spliced ​​by fixing parts such as rivets or colloids. , the second is to form the sheet metal at one time by means of continuous bending. [0003] Such as figure 1 As shown, it is a schematic structural diagram of the prior art. By heating and prolonging the forming time, the packaging boxes are bonded more tightly to each other, avoiding degumming and other phenomena, and ensuring product quality. However, in the bending and forming process of sheet metal plates Among them, it cannot adapt to the bending and forming of sheet metal plates of different thicknesses, the forming ...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 As shown, it is a schematic structural diagram of the prior art. By heating and prolonging the forming time, the packaging boxes are bonded more tightly to each other, avoiding degumming and other phenomena, and ensuring product quality. However, in the bending and forming process of sheet metal plates In the middle, it cannot adapt to the bending and forming of sheet metal plates of different thicknesses, the forming deformation is low, and deformation recovery is easy to occur
