Description

Technical Field

[0001] This utility model relates to the technical field of punching devices, and in particular to a punching device for a distribution cabinet door panel. Background Technology

[0002] Distribution cabinets are the final stage equipment in a power distribution system. They are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are a general term for motor control centers and are often used in situations where the load is relatively dispersed and there are few circuits. During the production of distribution cabinets, it is necessary to punch holes in the cabinet door panels.

[0003] In the prior art, patent document with publication number CN221388439U discloses a sheet metal punching device for a power distribution cabinet, which includes a clamping assembly, an adjusting assembly, and a punching assembly; the rear end of the clamping assembly is provided with an adjusting assembly for changing the punching position; the adjusting assembly is slidably connected with a punching assembly for punching holes in the power distribution cabinet.

[0004] During use, it was found that the above-mentioned device requires manual placement and alignment of the door panels, followed by positioning by clamping components. If the placement is not neat, the punching position will be deviated, resulting in low punching accuracy. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a punching device for the door panel of a power distribution cabinet.

[0006] This utility model discloses a punching device for a power distribution cabinet door panel, comprising a workbench, a controller, and a punching die. The controller is fixedly mounted on the workbench, and the punching die is mounted on the top of the workbench. The workbench has a cavity inside and also includes a guide component, a limiting component, and a punching component. The guide component and the limiting component are mounted on the workbench, and the punching component is mounted on the top of the workbench. In use, according to the position to be punched on the door panel, the guide component guides the door panel in the front-back direction, and the limiting component limits the rear end of the door panel, so that the position to be punched on the door panel coincides with the punching die through the cooperation of the guide component and the limiting component. Then, the punching component and the punching die are operated to perform the punching operation on the door panel.

[0007] Preferably, the guide assembly includes a first square rod, a first movable block, a first wing bolt, and a guide plate. A first strip-shaped opening is horizontally provided at the top of the workbench. A first square rod is fixedly installed in the first strip-shaped opening. The first square rod is slidably connected to two sets of first movable blocks. The bottom end of each set of first movable blocks is threadedly connected to a set of first wing bolts. The top ends of the two sets of first movable blocks are connected to the bottom ends of a set of guide plates. Based on the width of the door panel and the position of the horizontal drilling, the position of the first movable block on the first square rod is adjusted, thereby adjusting the spacing and position of the two sets of guide plates. After adjustment, the first wing bolt is rotated to tighten against the first square rod, thus locking the first movable block and the guide plate and improving flexibility.

[0008] Preferably, the limiting assembly includes a second square rod, a second movable block, a second wing bolt, and a limiting plate. The top of the workbench has two sets of second-order strip openings longitudinally arranged. A set of second-order square rods is fixedly installed in each set of second-order strip openings. A set of second-order movable blocks is movably fitted onto each set of second-order square rods. The tops of both sets of second-order movable blocks are connected to the bottom of the limiting plate, and the bottom of each set of second-order movable blocks is threadedly connected to a set of second-order wing bolts. Based on the position of the longitudinal hole in the door panel, the position of the second movable block on the second square rod is adjusted, thereby adjusting the distance between the limiting plate and the punching die. After adjustment, the second wing bolt is rotated, causing it to press against the second square rod, thus locking the limiting plate. The limiting plate limits the rear end of the door panel. The limiting plate, in conjunction with the two sets of guide plates, ensures that the position of the hole to be punched in the door panel coincides with the punching die.

[0009] Preferably, the punching assembly includes columns, a hydraulic cylinder, a lifting plate, a punching head, and a top plate. Two sets of columns are installed at the top of the workbench, with the tops of both sets connected to the bottom of the top plate. A hydraulic cylinder is installed at the top of the top plate, and a lifting plate is installed at the bottom moving end of the hydraulic cylinder. A punching head is installed at the bottom of the lifting plate. The rear end of the door panel is guided by two sets of guide plates and limited by a limiting plate, so that the perforated position on the door panel coincides with the punching mold. After the worker presses the door panel, the hydraulic cylinder extends via a controller, causing the lifting plate to lower the punching head. The punching head and the punching mold work together to punch the door panel.

[0010] Preferably, it also includes a wear-resistant layer, and the front end of the limiting plate is provided with a wear-resistant layer; the door panel avoids frictional wear on the front end of the limiting plate with the cooperation of the wear-resistant layer.

[0011] Preferably, it also includes guide plates, with a set of guide plates at the front end of each set of guide plates; under the guidance of the two sets of guide plates, the operator can quickly insert between the two sets of guide plates to achieve rapid positioning and improve convenience.

[0012] Preferably, it also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the worktable;

[0013] Four sets of adjustable feet work together to provide stable support for the equipment, improving its stability.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, according to the position of the door panel to be punched, the guide component guides the door panel in the front and back directions, and the limiting component limits the rear end of the door panel, so that the position of the door panel to be punched coincides with the punching mold through the cooperation of the guide component and the limiting component. Then, the punching component and the punching mold are operated to punch the door panel. Attached Figure Description
