Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a sheet metal punching equipment for a distribution box. Background Art

[0002] The distribution box is generally made of multiple metal plates. Commonly used metal plates include cold-rolled plates, stainless steel, aluminum alloy, etc., and the above plates will be punched with holes in various shapes such as rectangles, squares, and circles according to the design requirements of the distribution box. These holes are not only used to fix the electrical components inside the distribution box, but also play a role in heat dissipation and ventilation.

[0003] When punching metal sheets, laser punching, drill punching or punching press punching are used. For example, the Chinese utility model patent disclosed by publication number CN218985134U is a sheet punching machine. After the rear side of the sheet is fitted with the inner edge of the protrusion on the rear side of the punching table and one side of the sheet is fitted with the limit frame, the first slide is slid relative to the limit frame to make it close to the front side of the sheet, and the first screw is rotated by the first turning handle to make the first rubber pad close to the first slide, thereby limiting the longitudinal movable range of the sheet, and then the crank is turned to make the second After the handle is located above the plate, the second screw is rotated by the second handle to make the second rubber pad fit against the upper side of the plate and appropriately press the plate downward, and the application also cooperates with the punching mechanism to realize the punching processing of the metal plate. Although the application can realize multi-position punching operations on the metal plate, it can only open holes of a single aperture in the metal plate. Since the holes required for the metal plate used in the distribution box have different shapes due to different installation equipment or usage requirements, the application cannot realize the single opening of holes of different apertures and shapes in the metal plate.
