Automated Fire Box Roll Forming Machine for Steel Extinguisher Cabinet Production 300 pcs/hour

The Surface Mount Steel Fire Extinguisher and Hose Cabinet Roll Forming Machine is an automated production line developed by ZTRFM for manufacturing steel fire extinguisher cabinets, fire hose cabinets, and related metal cabinet door panels. By combining servo feeding, hydraulic punching, roll forming, hydraulic cutting, automatic conveying, and dual-end bending, the line streamlines multiple production steps into one continuous system.

It is suitable for manufacturers producing fire safety cabinets for commercial buildings, schools, hospitals, restaurants, industrial facilities, and other public or commercial projects. The automated process helps improve dimensional accuracy, production efficiency, and finished-door consistency while reducing repetitive manual operations.

Designed for Surface-Mount Fire Safety Cabinets

The machine is engineered to process steel sheet into accurately formed cabinet door panels used in surface-mounted fire extinguisher and hose cabinets.

Typical finished cabinets can use cold-rolled steel sheets with a white powder-coated surface. Depending on the customer's cabinet design, manufacturers can also choose different edge and door configurations, including:

• Rolled-edge or square-edge designs
• Engraved metal doors
• Etched glass door options
• Customized surface finishes
• Different cabinet widths and door dimensions

The cabinet door design can incorporate a 5/8-inch door stop, continuous hinges, and a zinc-plated handle. These components provide convenient access to fire extinguishers, valves, hoses, and other emergency equipment while maintaining a clean appearance.

Servo Feeding and Multi-Station Hydraulic Punching

Accurate feeding is essential when a cabinet door requires several holes, slots, or installation features. This production line uses a servo feeding system equipped with DELTA motors to control sheet movement and positioning.

The hydraulic cantilever punching system can perform multiple punching operations within the production cycle. It is designed to maintain accurate hole locations and repeatable dimensions throughout continuous production.

A sensor system monitors the punching process during operation. When an abnormal condition is detected, the system can stop the punching operation automatically. This helps protect the equipment, reduce defective panels, and improve operational safety.

14-Station Roll Forming System

After feeding and punching, the sheet enters the main roll forming section. The forming machine uses 45# steel shafts and GCR15 rollers to provide stable material forming and long-term mechanical durability.

The forming section includes 14 roller stations. Through progressive forming, the flat steel sheet gradually takes the required cabinet-door profile without relying on a single aggressive bending operation.

The production capacity can reach approximately 300 pieces per hour, depending on the cabinet door design, material specifications, punching requirements, and production configuration.

This continuous forming method helps manufacturers achieve:

• Consistent profile dimensions
• Stable forming quality
• Repeatable cabinet door geometry
• High production efficiency
• Reduced manual forming work

Hydraulic Post-Cutting for Accurate Panel Lengths

Once the profile reaches the required length, the hydraulic post-cutting system separates the finished panel from the continuous strip.

The cutting section is designed to produce accurate panel lengths while creating the required step features on the cabinet door. A channel-steel knife holder provides stable support during cutting and helps achieve clean cuts with reduced burr formation.

The post-cutting process allows the line to produce cabinet door panels according to preset production dimensions, improving consistency between individual pieces.

Automatic Conveying and Dual-End Bending

After forming and cutting, the finished panel is transferred automatically onto the electric conveyor table.

The conveyor moves each panel toward the bending section, where two bending stations complete the required end folds. Pneumatic clamping devices hold the panel securely during the bending operation to maintain stable positioning.

The dual bending arrangement allows both ends of the cabinet door panel to be processed efficiently. This reduces manual handling and helps maintain consistent bending dimensions from one panel to the next.

A dedicated production receiving table collects the finished products after bending. Operators can therefore remove completed cabinet doors from the end of the line without repeatedly handling panels between individual machines.

Hydraulic Power Unit for Stable Production

The hydraulic system provides the power required for punching, cutting, and other hydraulic operations.

The hydraulic station adopts a dual-motor configuration, providing sufficient power for continuous production while adding operational redundancy. An independent cooling fan helps dissipate heat generated during extended operation.

A built-in thermometer allows operators to monitor hydraulic oil temperature in real time. The system also incorporates optimized noise-control measures to create a more comfortable working environment.

Together, these features support stable hydraulic performance during long production cycles.

Siemens PLC and Touch Screen Operation

The entire production line is controlled through a PLC-based electrical system using Siemens electrical components.

The control system supports touch-screen operation, allowing operators to configure production parameters and monitor machine operation from a centralized interface.

Depending on the customer's requirements, the control system can also support:

• Remote control functions
• Multi-language operation
• Adjustable production parameters
• Automatic production control
• Sensor-based safety monitoring
• Automatic width adjustment

The automatic width adjustment function is particularly useful for manufacturers producing multiple cabinet sizes. It allows the production line to accommodate different dimensions without requiring frequent manual mold changes, helping reduce setup time and improve production flexibility.

Complete Automated Production Process

The machine integrates several processes into one coordinated production line:

Steel Coil → Servo Feeding → Hydraulic Punching → Roll Forming → Hydraulic Post-Cutting → Automatic Conveying → Dual-End Bending → Finished Cabinet Door

By connecting these processes, ZTRFM reduces the need for operators to transfer semi-finished panels between separate machines.

The result is a more streamlined manufacturing process with fewer manual handling steps, better production consistency, and improved workplace safety.

Technical Configuration

A Complete Solution for Fire Cabinet Door Manufacturing

For manufacturers looking to produce steel fire extinguisher cabinets and fire hose cabinet doors, the ZTRFM automated roll forming line provides a complete production solution rather than a standalone forming machine.

From servo-controlled feeding and hydraulic punching to roll forming, post-cutting, automatic conveying, and dual-end bending, each stage works together as part of one production system. This integrated design helps manufacturers improve productivity, reduce manual handling, and maintain consistent cabinet door quality.

ZTRFM can also customize the production line according to the required cabinet size, door profile, punching layout, material thickness, forming configuration, and automation level, making the equipment suitable for different fire safety cabinet manufacturing projects.
