Problems solved by technology

[0002] Ventilation pipes are metal or composite pipes used in ventilation and air-conditioning engineering of industrial and civil buildings. They are a kind of municipal infrastructure for air circulation and reducing the concentration of harmful gases. The shapes of ventilation pipes are various, and rectangular ventilation pipes are one of the commonly used ventilation pipes. , when constructing rectangular ventilation ducts, it needs to be cut. The common equipment for cutting rectangular ventilation ducts is a cutting machine. At present, manual cutting is usually used. It is easy to cause safety hazards when cutting, so it needs to be improved
