Fire dampers produced by the fire damper production line effectively isolate fire sources and smoke during a fire, preventing the spread of fire and making them crucial for building safety. They close rapidly in the event of a fire, blocking smoke and flames from spreading to other areas through ventilation ducts, thus protecting other parts of the building from the fire. Furthermore, fire dampers are typically linked to ventilation equipment (such as fans); when the damper closes, it automatically stops the fan, preventing combustion and reducing fire risk. When closed, the fire damper sends a signal to the fire alarm system, providing critical information for timely response.
However, a complete fire damper cannot be produced by a single machine; it requires various types of fire damper making machines. This article from KINGREAL Roll Former introduces a complete fire damper production line solution.
1)Fire Damper Frame Machine
This fire damper frame machine produces robust fire damper frames of different sizes through processes such as uncoiling, leveling, punching, forming, bending, and cutting. These fire damper frames serve as the core load-bearing structure and installation reference for the fire damper. It serves as the mounting framework for all internal components, including blades, actuators, and connecting rods. Connected to ventilation ducts at both ends, it must withstand airflow pressure and high-temperature impacts during fires, ensuring the stability and fire resistance integrity of the overall valve structure. This fire damper frame machine typically processes 1.5-2.0mm thick galvanized steel sheets at speeds up to 15m/min, adjustable to meet production needs. The fire damper frame machine produces fire damper frame plates with a length error of ±0.5mm/m and a punching hole spacing error of ±0.3mm/m. Notably, KINGREAL Roll Former has optimized the fire damper frame machine's design and innovative configuration, transforming manual bending into automatic bending, reducing labor costs and improving production efficiency and quality.
2)Fire Damper Blade Making Machine
This fire damper blade making machine consists of precision components such as a decoiler, roll forming machine, and cutting station. It can produce various types of fire damper blades, including curtain fire damper blades, fire damper v locking blade, and VCD airfoil blades, allowing customers to choose the appropriate fire damper blade making machine based on their project requirements. The fire damper blades, as the core of the flow control in the damper system, are typically arranged in a bi- or tandem configuration. Under normal operating conditions, rotation changes the opening degree to precisely regulate the airflow within the duct. In case of fire, the fire damper blades close rapidly under the drive of the actuator, physically blocking the spread of smoke and fire along the duct. This fire damper blade making machine typically processes galvanized steel sheets with thicknesses ranging from 1.2-1.5mm/1.8-2.0mm, operating stably at a speed of 15m/min. The fire damper blade making machine produces fire damper blades with high consistency and precision, with sheet length error of ±0.5mm/m; product straightness of ±0.8mm/m; and product twist of ±1.0mm/m.
3)HVAC Damper Riveting Table
The HVAC damper rivet table consists of outer frame riveting (four-rivet), corner brace riveting (four-rivet), support bar riveting pliers (double riveting), and windshield strip riveting pliers (single riveting). Double riveting and single riveting can be configured according to customer requirements (rotating wall-mounted, rotating bracket). Achieving assembly results with no high-temperature deformation and high connection strength ensures that the fire damper remains stable under vibration and high-temperature environments for extended periods.
4)HVAC Damper Spring Leaf Machine
This HVAC damper spring leaf machine primarily processes 0.2mm 301H stainless steel, producing spring leaves with high precision. The length error of the sheet metal is ±0.5mm/m; the punching hole spacing error is ±0.3mm/m. As a critical sealing component, the spring leaf utilizes elastic deformation to ensure a tight fit between blades and between the fire damper blade and the fire damper, controlling air leakage within specified limits during a fire. Some spring leaves also participate in the reset mechanism of the actuator, ensuring rapid fire damper blade closure after the fusible link melts.
5)HVAC Damper Supporting Bar Machine
This HVAC damper supporting bar machine processes 1.5-2.0mm galvanized sheet material at speeds up to 15m/min. The produced supporting bars have high precision, with a length error of ±0.5mm/m and a punching hole spacing error of ±0.3mm/m. The supporting bars serve two main purposes: first, they enhance the deformation resistance of large fire dampers, preventing fire damper frame distortion due to excessive wind pressure; second, they provide multi-point support for the fire damper blade shaft, ensuring smooth and stable operation of the blades over long periods, maintaining adjustment accuracy.
