Fire Extinguisher Box Roll Forming Machine
The fire extinguisher box cold bending forming machine is the core rolling equipment in the fire extinguisher box production line. It is specifically designed to continuously form the four-sided frame outline of the fire extinguisher box body by progressively bending steel strips through multiple passes. Fire extinguisher boxes are shallow-depth boxes (typically 200-300mm), requiring high forming precision and springback control. This equipment adopts high-precision cold bending forming patented technology, equipped with multiple sets of Cr12 die steel CNC machined rollers. The rollers are quenched to a hardness of HRC58°-60° and synchronously driven by a gearbox to ensure uniform deformation and dimensional stability of the steel strip during high-speed operation. It has a daily production capacity of 1000 units and is specifically suitable for the one-time cold bending manufacturing of single and double-bottle fire extinguisher boxes.

Product Advantages
- Patented Technology for Shallow-Depth Box Rebound Control: Fire extinguisher boxes are shallow (200-300mm), making bending and rebound a significant issue. The equipment utilizes patented high-precision cold bending technology. The roller forming design precisely calculates the rebound compensation for different thicknesses of sheet metal during shallow-depth bending. Through multi-pass progressive forming, stress is released gradually, ensuring precise 90° angles at the four corners of the box and stable opening dimensions.
- Multi-Pass Roller Forming for More Uniform Deformation: The equipment employs a multi-set roller progressive cold bending process. The steel strip is gradually bent to the target angle through each pass, avoiding stress concentration and surface scratches caused by large-scale bending in one go. The roller forming design is optimized for the thin sheet metal of fire extinguisher boxes (commonly 1.0mm), resulting in undamaged sheet metal surfaces and a high-quality finished product.
- High-Efficiency Production Capacity, Thousands per Machine per Day: The equipment operates continuously at a stable speed of approximately 110 boxes per hour, achieving a daily production capacity of 1000 boxes, fully meeting the delivery needs of large-volume orders for fire extinguisher boxes.

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: Can the cold bending forming machine for fire extinguisher boxes process rounded corner boxes?
A: The standard configuration is right-angle bending. For fire extinguisher boxes with rounded corners or edges, a custom-made rounded corner forming roller set is required, which falls under the non-standard customization category. After the customer provides the box cross-section drawings, our technicians can assess the feasibility and lead time for customization.
Q: Will there be roller marks on the box surface after forming?
A: No. The roller surface undergoes precision grinding and high-gloss treatment, achieving a hardness of HRC58°-60%, effectively protecting the sheet metal surface during high-speed operation. When using galvanized sheet metal, the galvanized layer is intact and scratch-free after forming, resulting in a smooth box surface that can directly proceed to the spray painting process without grinding.
