In today’s world, where infrastructure construction is becoming increasingly sophisticated and modular, tunnel and culvert engineering demands higher standards for efficient, precise, and durable lining solutions. Leveraging its leading engineering technology, BEN-THOMAS has launched a new generation of Segmental Tunnel Linings Machine Production Line. With a highly integrated, intelligent, and stable manufacturing system, this new line redefines the production standards for steel lining structural components, providing a robust and reliable productivity engine for contractors and manufacturers worldwide.

 

Core Technology: Seamless Integration of Four Precision Processes:

This Metal Tunnel Lining Segments Machine Production Line adopts a modular, segmented design, integrating four core processes: uncoiling, profiling, punching, and bending, to achieve continuous automated production from steel coils to formed lining panels.

 

High-Precision Uncoiling and Leveling System

Equipped with a heavy-duty hydraulic uncoiler and a multi-roll precision leveler, it can stably process various high-strength steel coils with thicknesses ranging from 1.5mm to 10mm.

A built-in tension closed-loop control system ensures that the sheet metal is stress-free before entering the forming section, achieving optimal flatness and laying the foundation for subsequent high-precision processing.

Heavy-Duty Shape Profiling Unit

Utilizing servo-driven multi-pass progressive shape profiling technology, the flat sheet is gradually cold-bent into the required waveform or structural shape through a precision forming roller group.

The forming process is stable, and the surface accuracy is high, ensuring that each lining plate has consistent cross-sectional geometry and mechanical properties.

High-Precision Servo Punching System

One of the core advantages of this production line. Equipped with a multi-axis servo-driven punching unit and long-life dies.

Mechanical positioning achieves high-precision punching, ensuring a tight fit for subsequent on-site bolt connections, significantly improving structural integrity and installation efficiency.

Supports flexible settings for various hole layout patterns to adapt to the connection requirements of different engineering standards. Hydraulic Bending Workstation

Based on the tunnel’s designed curvature, a PLC-controlled multi-point hydraulic bending machine precisely bends the formed plates multiple times to ensure the assembly accuracy of the curved lining panels.

 

Exceptional Value: Creating Core Competitive Advantages for Customers

Extremely Stable Operation, Ensuring Continuous Production

The entire lining tunnel plate making machine utilizes world-class brands (such as Siemens and Rexroth) for its core components, including servo systems, hydraulic components, and PLC controllers, ensuring 24/7 continuous and stable operation with an industry-leading Mean Time Between Failures (MTBF).

Customizable Thickness Support, Strong Material Adaptability

Key components of the production line feature a modular design, allowing for customized reinforcement based on the thickness requirements of the customer’s main production materials. Whether it’s thin plates for light-duty drainage culverts or thick plates for heavy-duty mining tunnels, optimal forming solutions are provided.

Extremely Low Scrap Rate, Achieving Cost Reduction and Efficiency Improvement

Through precise length cutting and optimized layout and punching processes, material utilization is maximized. Compared to traditional manual material cutting and step-by-step processing, this tunnel lining steel plate flange making machine can reduce the overall material scrap rate to below 3%, directly improving profit margins.

Highly Automated, Significantly Saving Labor

The entire line requires only 1-2 operators monitoring the process from roll material loading to finished product stacking in the control room. Reduced reliance on skilled workers lowers labor costs and management complexity, making it particularly suitable for large-scale production.

High Return on Investment (ROI) and rapid cost recovery

With its core advantages of high efficiency (5-8 times the output of traditional methods per shift), low waste, and minimal manpower, customers can typically recover their production line investment within 12-24 months through increased capacity and cost savings, resulting in significant long-term benefits.
