Automatic M Shape Purlin Cold Roll Forming Line with PLC Control 0-20m/min

Automatic M Shape Purlin Cold Roll Forming Line with PLC Control

Automatic M Shape Purlin Cold Roll Forming Line with PLC Control is a specialized equipment used for cold bending M-shaped steel, widely used in mining support, steel structure construction, and industrial manufacturing fields. It uses continuous rolling technology to cold bend steel plates into M-shaped steel strips with specific cross-sectional shapes, which have the characteristics of high strength, high precision, and efficient production.


Core Features：

1.High strength structural design
After cold bending, the bending section modulus of M-shaped steel is 37 times higher than that of flat steel strip, and the stiffness is increased by about 70 times. At the same time, cold rolling hardening increases the tensile strength by 12% -15%, significantly enhancing the support performance.

2.High precision automation control
The equipment adopts a fully automated assembly line design, equipped with CNC punching, laser positioning, and intelligent cutting systems. The length error is controlled within ± 1mm to ensure product consistency.

3.Remote operation and digital management
Equipped with IoT modules, it supports remote status monitoring, fault diagnosis, and parameter optimization. Some enterprises have already connected to the Siemens cloud platform, providing 24/7 technical support.


Main application scenarios：

• Mine roadway support
The combination of M-shaped steel strip and anchor rod forms an integral load-bearing structure, which is widely used in underground coal mine tunnels, working face cutting holes, chambers and other scenarios, effectively controlling the deformation of unstable surrounding rock. Compared with traditional I-beams, each frame can save more than 850kg of steel.

• Steel structure construction engineering
Manufacturing of light steel keel or load-bearing components for buildings such as factories, warehouses, bridges, etc., especially suitable for modern projects with strict construction requirements, the construction period can be shortened by 40%.

• New energy and infrastructure construction
M-shaped steel strips can be used as supporting materials in photovoltaic power plants, tunnel reinforcement, and subway engineering. They can be combined with T-shaped fixtures for the foundation structure of rooftop photovoltaic systems.

Conclusion：

The M Purlin Machine, as a core equipment in the field of mining support and structural profile manufacturing, is redefining the production efficiency and quality standards of M-shaped steel with its advantages of fully automatic continuous production, high-precision cold bending forming, online punching, and hydraulic cutting to length. The entire line adopts PLC intelligent control, with intuitive operation. Only 1-2 people are needed to complete the entire process from unwinding, leveling, punching, forming to cutting and stacking; The rolling mill is quenched with high-quality alloy steel and treated with hard chrome, which has strong rigidity, wear resistance and durability, and supports long-term stable operation at full load.

Whether it is M-shaped steel strips for coal mine roadway support, tunnel and slope support steel, or M-shaped profiles for building structures, bridge templates, and storage shelves, this equipment can help customers seize the opportunity in fierce market competition with more stable forming accuracy, lower material loss, and faster delivery speed.
