Description

Technical Field

[0001] The utility model belongs to the field of distribution box hole opening devices, and in particular relates to a distribution box line inlet hole opening device. Background Art

[0002] The punching device for distribution box production is a device used to punch holes in the distribution box plates that make up the distribution box during the distribution box production process, making it easier to process the distribution box plates into distribution boxes. It has been widely used in the field of distribution box production.

[0003] Chinese patent application number CN220462303U discloses a punching device for distribution box production, comprising a base, a bracket fixedly connected to a surface of the base, a punching machine fixedly connected to a surface of the bracket, an inner cavity of the base driving a placement seat to move via a displacement mechanism, the inner cavity of the placement seat being provided with a stabilizing mechanism, the displacement mechanism including a transverse plate. The utility model relates to the technical field of distribution box production. The punching device for distribution box production, by activating a first motor to drive a connecting bolt to slide back and forth along the inner surface of a transverse groove, the connecting bolt drives the distribution box plate to move back and forth via the stabilizing mechanism, thereby adjusting the front and rear punching positions, and activating a second motor to drive a sliding block to slide left and right along the surface of a sliding rod, while the connecting bolt drives the distribution box plate to move left and right via the stabilizing mechanism, thereby adjusting the left and right punching positions. The adjustment process is simple and fast, effectively improving the punching efficiency of the distribution box plate. However, the punching device for distribution box production in the application, by driving four stabilizing plates to slide synchronously horizontally via a stabilizing motor, results in the four stabilizing plates sliding the same distance, resulting in the device only being suitable for the processing and positioning of square distribution boxes, which affects the adaptability of the device.
