Decoiler

We install press-arm on the decoiler to press the steel coil to secure the coil during replacements, preventing any sudden release that could potentially harm workers. Additionally, we incorporate protective iron-leaves to prevent steel coils from slipping during the uncoiling process. This design not only safeguards workers but also ensures the protection of both the steel coils and the machines.

Leveler

The leveling machine, an essential component in the production process, effectively removes any irregularities from the steel coil, enhancing its flatness and parallelism. This also improves the quality of both the steel coil and the produced box beam. Given that the steel coils used for box beam production typically have a thickness of 1.5-2 mm, the leveling machine is indispensable. Unlike conventional leveling machines consisting of 2 upper rollers and 3 lower rollers, we've configured a specialized 3-upper-roller and 4-lower-roller leveling machine to meet the specific leveling requirements for this thickness.

Pre-cut

Our customer who ordered this roll forming machine typically require the production of at least 13 different sizes, all of which can be accommodated by this single machine. We have configured a pre-cutting device to make it easier to replace steel coils of different widths and thicknesses, while also helping to avoid the waste of steel coils. Following this stage, the steel coil proceeds to the roll forming process.

Roll former

This roll forming machine is built with a robust cast-iron structure, constructed as a single solid piece of iron, ensuring exceptional durability and stability. What sets this machine apart is its automatic size-adjustment function, enabling the production of different-sizes box beams. For instance, the forming stations can move outward on rails to reduce height or inward to increase height. Customers only need to input the desired cutting length and number via the PLC control panel, and the machine will automatically adjust, offering exceptional ease of use and efficiency.

Platform

After roll forming, profiles are transported to the turnover-platform, where one of them is automatically flipped, aligning two profiles with one on top of the other. Guiding rollers ensure precise alignment, and then the 2 profiles are fed into the seaming machine and seamlessly automated, requiring no manual intervention.

Seaming machine

The seaming machine efficiently joins two profiles securely together. The seaming rollers can also move on rails to accommodate the production of various-size box beam. Customers only need to employ one manual operator to control the PLC, eliminating the need for manual welding and the associated cost of an additional welder.

PLC+encoder

Our control panel offers multiple language options, allowing you to control production speed, production dimensions, and cutting lengths, among other parameters. Within the production line, we employ Japanese-brand encoders for precise control of cutting lengths, minimizing waste from incorrect cuts. We also provide customization services, including motor models, brands, and electronic component brands, tailored to your specific needs.
