Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plate processing, and in particular to a plate positioning and cutting device for processing a power distribution cabinet shell. Background Art
[0002] In the field of power distribution cabinet manufacturing, sheet metal processing is a key step, involving multiple operations such as precise cutting, bending, punching, welding, etc. of power distribution cabinet side panels, columns and other components. Traditional processing methods often rely on manual operation or semi-automatic equipment. These methods have certain limitations in positioning, production efficiency, processing accuracy and repeatability. In order to improve production efficiency and product quality, the power distribution cabinet manufacturing industry usually uses highly automated equipment such as rolling mills, bending machines, CNC punching machines, hydraulic presses, electric welders, unloading machines, shearing machines, etc. These equipment increase the degree of automation in the manufacturing process, improve processing accuracy and consistency, and reduce labor costs and error rates. However, even on a highly automated production line, sheet metal positioning and cutting is still a key link, especially when it comes to large-scale, high-precision production of power distribution cabinet shells. The sheet metal needs to be accurately positioned before processing to ensure the accuracy of cutting and hole positions, which is crucial for subsequent bending, punching, assembly and welding processes.
[0003] The utility model in the prior art has an authorization announcement number of CN113967803A, and its name is: a plate positioning and cutting device for processing a distribution cabinet shell, comprising: a cutting device body, a movable frame is provided on the outer side of the cutting device body, and a material receiving trough is provided on the inner side of the cutting device body, and positioning structures are provided on both sides of the material receiving trough on the inner side of the cutting device body. The utility model provides a discharge plate, a buffer plate, a first hydraulic push rod and a rotating roller, and the finished plate stops on the discharge plate, and the first hydraulic push rod drives the rotating roller to move downward, so that the discharge plate moves downward with the rotating roller at one end under the movable support of the support rod and the rotating seat, and at the same time the second hydraulic push rod drives the rubber top block to move up and down to collide with the discharge plate, so that the finished plate slides down onto the buffer plate under inertia and vibration force, so that the plate slides out to the outside of the cutting device body, and the plate collection is completed, which effectively solves the problem of low efficiency in collecting the finished plate after cutting. However, the patent clamps and moves the plate through threaded rods, clamping plates, movable sleeves and other components, and the multi-step operation may lead to inconvenience in use and limited efficiency. The operator needs to be familiar with the coordinated work of multiple components, and the equipment may be more time-consuming and labor-intensive in calibration and maintenance.

Through the arrangement of structures such as the top pressure block 10 and the side push plate 18, the plate to be cut is placed on the top of the cutting table 5, and then the cylinder 11 is started by the controller 20. The cylinder 11 is pulled by the push rod 16 and the top plate 12 and the mounting plate 13 move downward. When the mounting plate 13 moves downward, the first rotating block 9 movably hinged inside the mounting plate 13 rotates and moves downward. At the same time, the top of the top plate 12 is separated from the bottom of the push rod 16, and the strong spring 17 pushes the second rotating block 19 to rotate and reset. The side push plate 18 on the second rotating block 19 pushes one side of the cut plate to move toward the side baffle 8 until the cut plate is tightly fitted with the side baffle 8, and at the same time, the top pressure block 10 is pressed against the top of the plate to be cut.
