Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a laser cutting device for ring network box bodies. Background Technology

[0002] A ring main unit (RMU) is an important type of electrical equipment used in ring-shaped power distribution systems, primarily for power distribution and protection. It is typically made of metal, possessing good corrosion resistance and strength, and can operate stably in various environments. The RMU generally contains switching equipment, protective devices, and measuring instruments for monitoring and managing the power system. Due to the high safety requirements of its design, the RMU has a complex structure and requires high manufacturing precision. To meet these requirements, advanced laser cutting technology is used during the manufacturing process to ensure cutting accuracy and processing quality.

[0003] Patent CN219113186U discloses a laser cutting device for processing electrical boxes in metal products. The device includes an operating table, a gantry frame fixed to the upper surface of the operating table, a processing plate located inside the gantry frame and on the upper surface of the operating table, and a fixed base fixedly connected to the upper surface of the processing plate. A first motor is bolted to the top of the fixed base. This invention provides a laser cutting device for processing electrical boxes in metal products. The device uses the first motor to rotate its output shaft, which drives a drive gear to mesh with a transmission gear, causing a spur gear to rotate. This spur gear meshes with two racks, causing a clamping plate to slide relative to the outer wall of a guide rod. The guide rod increases the stability of the clamping plate during movement. This design allows the clamping plate to hold the electrical box above the processing plate, thus maintaining the stability of the metal electrical box during laser cutting and making the cutting more precise.

[0004] While the aforementioned existing technologies can effectively clamp the metal electrical box, ensuring its stability during the cutting process and thus improving cutting accuracy, laser cutting generates odors. These odors primarily originate from the burning gases and chemical reactions of the material, and are somewhat irritating. This not only affects the air quality of the working environment but may also pose a potential threat to the health of workers. To address this issue and improve the safety and comfort of the working environment, there is an urgent need to develop a laser cutting device for ring network box bodies that can reduce odor generation while meeting cutting accuracy and efficiency requirements, thereby protecting the health of workers.

[0031] The laser cutting device for the ring network box includes a laser cutting machine body 1, which is the main equipment for integrating cutting functions. The specific working principle of the laser cutting machine body 1 is the existing technology, such as the detailed working principle of the laser cutting device for processing metal product electrical boxes disclosed in patent publication number CN219113186U, which will not be repeated here.

At the same time, the second driving member 15 drives the processing plate 14 to move left and right to adjust the cutting position and complete the high-precision cutting of the box body. During the cutting process, the fume hood 30 captures the generated smoke and odor gas in real time and transports the exhaust gas to the purification box 40 through the L-shaped suction pipe 3 and the L-shaped duct 7. The exhaust gas passes through the primary filter plate 41 to filter large particles of dust and the activated carbon filter plate 4 in sequence. 2. The filter adsorbs volatile organic compounds and odors, while the high-efficiency filter plate 43 traps fine particulate matter. The purified gas is driven by the exhaust fan 6 and discharged through the exhaust pipe 5. The dustproof net 50 at the outlet of the exhaust pipe 5 prevents external dust from flowing back in.
