High-Speed L Purlin Roll Forming Machine for Steel Structure

In the field of architectural steel structure and mechanical manufacturing, the accuracy of corner supports and connectors directly determines the stability of the overall structure. As the core model of special-shaped cold bending equipment, our High-Speed L Purlin Roll Forming Machine is designed for efficient mass production of unequal or equal angle steel. With excellent performance of "one-time forming, fixed length cutting, and high consistency", it helps enterprises reduce costs and increase efficiency.

Equipment Introduction: Smart Production Line from Coil to Finished Product

The L-shaped steel mill is an automated equipment that continuously and gradually bends metal coils such as galvanized sheets and cold-rolled steel coils through multiple cold bending rolls, ultimately producing right angle "L" section profiles.

The entire line consists of a feeding machine, a feeding leveling device, a continuous cold bending forming host, a hydraulic cutting device, a finished product receiving platform, and a PLC intelligent electrical control system. Just input the production parameters, and the equipment can complete the fully automatic process from passive feeding, precise calibration, to roll forming and follow-up cutting, completely bidding farewell to the low efficiency and high loss of traditional stamping angle steel.

Application scenario: ubiquitous right angled skeleton

L-shaped steel, as an important structural connector and support, is widely used in the following fields:

• Steel structure building:
used for purlin support, roof and wall substructure, column support, as well as equipment base and embedded parts, to ensure the stability of the building skeleton.

• Photovoltaic bracket system:
producing high-strength unequal angle steel, used as beams and columns for solar panel brackets, with both load-bearing and anti-corrosion properties.

• Cable tray and pipeline support:
As the cross arm and pipe gallery support hanger of cable tray, it meets the standardized installation requirements of power and petrochemical engineering.

• Storage shelves and logistics equipment:
produce columns, transverse slant support and pallet frames of heavy shelves to ensure the reliable bearing of the three-dimensional warehouse.

• Agricultural and light industry facilities:
used for greenhouse skeleton, livestock fence, workbench frame, partition keel, etc., with low cost and easy connection.

Core feature: Why do global manufacturers choose us?

1.High precision cold bending process:
using high-quality chromium steel rollers (surface quenching treatment), CNC precision machining ensures that the verticality and straightness errors on both sides of the L-shaped steel are controlled within a very small range, with high diagonal accuracy, fully meeting the high standard requirements of welding robots and assembly lines.

2.Flexible changeover production:
Through the design of quick change roller sets, the same equipment can produce equilateral or unequal L-shaped steel of different specifications (such as L30 to L100) and thicknesses (1.5mm-5.0mm). Convenient regulation adjustment significantly reduces downtime.

3.Full servo intelligent control:
equipped with PLC control system and touch screen human-machine interface, supporting length setting, batch counting, and automatic deceleration and shutdown. Flying saw or hydraulic cutting synchronous cutting, with a smooth and burr free cut, and a finished product length accuracy of ± 0.5mm.

4.Stable and durable structural design:
The overall bed body is welded with thick steel plates and subjected to stress relief treatment, with strong load-bearing capacity. The transmission system adopts a strong torque motor with a reducer and gearbox for distributed drive, which runs smoothly for a long time and has a service life of over 10 years.
