Fire Cabinet Roll Forming Machine
The Fire Cabinet Roll Forming Machine is the core roll forming equipment in the fire cabinet production line. It is specifically designed to continuously form the four-sided frame outline of the fire cabinet by progressively bending steel strips through multiple passes. The rollers are hardened to HRC58°-60% and synchronously driven by a gearbox, ensuring uniform deformation and dimensional stability of the steel strip during high-speed operation. The equipment occupies 21.5×2.0×1.8 meters, has a total power of approximately 27kW, operates on a 380V three-phase power supply, and has a production speed of approximately 110 cabinets per hour, with a daily capacity of 1000 units. It is suitable for the one-time cold bending manufacturing of fire hydrant boxes, fire extinguisher boxes, and other fire cabinets.

Product Advantages
Multi-pass progressive forming for precise springback control
The equipment employs a multi-roll progressive cold bending process. The steel strip gradually bends to the target angle as it passes through each roller pass, avoiding cracking or excessive springback caused by a single large-angle bend. Leveraging patented high-precision cold bending forming technology, the roller design precisely calculates the springback amount for plates of different thicknesses, resulting in precise angles and stable dimensions for the formed box, meeting the stringent requirements of 90° right angles and high squareness for fire-fighting boxes.
Cr12 hardened rollers for long wear resistance and lifespan
The forming rollers are CNC machined from Cr12 mold steel, hardened to HRC58°-60%, with a high surface finish and excellent wear resistance. Under high-load operation conditions of 1000 units per day, the rollers have a normal service life of 3-5 years without replacement, maintaining stable forming accuracy over a long period, significantly reducing maintenance costs and downtime losses.
Gearbox Synchronous Drive Eliminates Dimensional Deviations
All forming rollers are synchronously driven by a gearbox, ensuring precise transmission ratios and eliminating slippage and cumulative errors. Compared to chain or belt drives, gearboxes have a higher load-bearing capacity, ensuring that the linear speeds of the rollers on both sides of the steel belt are completely consistent. This results in a symmetrical box body with equal diagonal dimensions after forming, eliminating twisting and misalignment caused by asynchronous speeds.

FAQ
Q: Are you a factory or a trading company?
A: We are a factory located in Weifang, China. It possesses over twenty sets of advanced equipment, including a new precision machining center, NC lathes, CNC wire EDM machines, and a large automotive profile bending test platform. You are welcome to visit our factory at any time.
Q: What is the difference between a cold bending forming machine and a regular bending machine?
A: A regular bending machine performs a single-pass bending, bending one edge at a time, requiring multiple positioning and clamping operations. A cold bending forming machine uses multiple passes of rollers for continuous rolling forming. The steel strip passes through each pass of rollers at a linear speed, gradually forming the strip. It allows for continuous production without interruption, resulting in significantly higher production efficiency and better consistency in forming accuracy compared to a regular bending machine.
Q: What are the thickest and thinnest plates that the equipment can process?
A: The standard configuration is suitable for cold-rolled or galvanized steel strips with a thickness of 0.8-2.0mm. Fire truck boxes commonly use thicknesses of 1.0-1.5mm, where the equipment provides the best forming effect. For processing thinner (<0.8mm) or thicker (>2.0mm) plates, the roller pattern design and forming gap can be customized according to customer requirements. Specific details need to be confirmed during the selection process.
