Description

Technical Field

[0001] The utility model belongs to the technical field of plate processing of power distribution cabinets, and in particular relates to a plate bending and forming device for manufacturing power distribution cabinets. Background Art

[0002] The distribution cabinet is one of the important control units in the power system. The distribution cabinet mainly includes an outer shell and its internal control elements. When the outer shell of the distribution cabinet is processed and produced, the plate needs to be bent so that the bent plates can be spliced ​​into a cabinet. The bending of the plate is mainly completed by a bending machine. The plate is squeezed into the lower die through the upper die on the bending machine, so that the plate is bent and deformed in the lower die to achieve the bending work. However, this type of bending machine has great limitations when used. For example, the upper die and the lower die on the bending machine are used in combination, and the bending angle is fixed. When bending processing at different angles is required, the upper die and the lower die need to be removed and replaced with other models of upper die and lower die. Since the upper die or the lower die is spliced ​​by multiple separate modules, it is difficult to replace it and the operation is extremely inconvenient. At the same time, each mold on the bending machine can only achieve bending processing at a single angle.

[0003] To this end, a plate bending device for the production of low-voltage distribution boxes with a publication number of "CN117259505A" is disclosed, comprising a pallet, a bending plate and a pressure plate. The pallet and the bending plate are horizontally coplanar and close to each other. A support is fixed at the bottom of the pallet, and the upper surface of the support extends horizontally to the outside of the pallet. The bottom of the bending plate contacts the extended upper surface of the pallet, and the bottom of the support is set as an arc surface, and a guide plate is slidingly provided on the arc surface of the support. The plate is bent by flipping the bending plate and directly pushing the plate to bend, which greatly simplifies the bending method of the plate, facilitates the rapid forming of the plate, and the bending angle of the plate can be directly determined according to the flipping angle of the bending plate, so the plate can be bent at any angle.

[0004] However, for the above-mentioned plate bending device for the production of low-voltage distribution boxes, although the first connecting plate can push the sliding sleeve to slide in the through groove through the second connecting plate, the first leaf spring undergoes elastic deformation, thereby generating an elastic force on the sub-plate through the first leaf spring, there are still the following obvious defects during use: however, the downward pressure generated by the bending plate bending the plate will cause the elasticity of the first leaf spring to deform, causing the sliding sleeve to slide on the first leaf spring, which will cause one end of the second connecting plate to move downward, causing one end of the sub-plate to move downward to produce an angle change, thereby causing an error in the bending angle of the plate.
