Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a fixing clamping device used for finishing of sheet metal of a low-voltage distribution cabinet. Background Art

[0002] As the name implies, low-voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high-voltage switch cabinets, which are then stepped down by transformers and led out to low-voltage distribution cabinets. Low-voltage distribution cabinets are then led to distribution boards, control boxes, and switch boxes for various power users. Inside, some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices are assembled into one to meet the design functional requirements of the distribution device. When the distribution cabinet is produced, it is generally necessary to perform sheet metal processing on it. During the sheet metal processing, the surface of the distribution cabinet generally needs to be fine-finished. At this time, a fixed clamping device for sheet metal finishing of low-voltage distribution cabinets is required.

[0003] After searching, the applicant found that a Chinese patent disclosed "a fixed clamping device for sheet metal processing" with a publication (announcement) number of "CN218873510U". The patent mainly lifts the clamping plate by rotating the adjusting screw to clamp the sheet material together with the top plate. After the sheet material is bent, the edge can be pressed against the angle between the top plate and the clamping table to clamp the sheet material from the four corners. At the same time, the distance and height of the clamping table can be adjusted according to the size of the sheet material, which is suitable for clamping and fixing more sheet materials.

However, when the low-voltage distribution cabinet is subjected to sheet metal processing to perform fine processing on both surfaces of the plate, after processing one side, the plate needs to be removed from the clamping device, turned over, and then fixed. This method is more cumbersome to operate, which affects the efficiency of the distribution cabinet sheet metal and also brings greater work intensity to the staff. Utility Model Content
