Full Automatic CU Purlin Roll Forming Machine

Here is the working video of this machine for everyone to watch:

In the booming development of the construction industry, efficient and precise production equipment has become the key to enhancing competitiveness. With the popularization of new building models such as prefabricated buildings and high-rise steel structures, traditional production equipment is no longer able to meet increasingly stringent construction standards and schedule requirements. CU type steel machine, as an advanced equipment specially designed for the construction field, integrates CNC automation technology and precision forming technology, and can achieve high-speed continuous production of 15 meters per minute while ensuring ultra-high machining accuracy of ± 0.3mm. Its modular design not only supports rapid switching of various cross-sectional profiles such as C-shaped and U-shaped, but also effectively solves the problem of steel deformation through an intelligent correction system. With its excellent performance and reliable quality, it brings a new production experience to the construction industry. ​

Product Attributes :

Strong production capacity：

The CU type steel machine can efficiently produce C80-300 type steel and U80-300 type steel (purlins), which are widely used in building construction and factory buildings, and undertake the important task of supporting beams and wall beams. The applicable range of material thickness is 1.0-3.0mm, with up to 20 forming passes, ensuring the stable structure of the steel section. The molding speed can reach 18 meters per minute, coupled with an 18.5KW variable frequency speed control motor drive and gear chain transmission, ensuring production efficiency while achieving reasonable utilization of energy. ​

Precise manufacturing process：

Accurate and smooth feeding guidance: The equipment is equipped with positioning rollers, which can flexibly adjust the positions of both ends and accurately adapt to the feeding width; The guide roller adopts an upper and lower circular roller design, making the feeding process smoother and more stable, reducing material jamming and damage, and laying a good foundation for subsequent forming processes. ​
Excellent quality of roller shaft components: The main shaft diameter reaches 75/90mm, and high-quality 45 # round steel is selected to ensure the high strength and stability of the equipment. The roller material undergoes precision machining and hard chrome plating treatment, followed by mirror polishing and heat treatment. This not only improves the surface hardness and wear resistance, but also makes the cold bending process smoother, effectively enhancing the surface quality of the product. ​
Fine and reliable cutting after molding: using a guide mechanism that moves up and down for cutting to ensure a smooth and deformation free cut; The cast iron tool holder has excellent shock absorption and impact resistance, and can withstand high-intensity workloads. The blade is made of Cr12Markov material, with a cutting life of over 1 million times, greatly reducing the frequency and cost of tool replacement. The rear scissor frame is made of Q235 steel plate, which undergoes rough milling, annealing treatment, and precision machining to ensure cutting accuracy and long-term stable operation of the equipment. ​

Intelligent control system：

The CU steel machine is equipped with Delta/Schneider high-precision PLC electrical control system, combined with Schneider heavy-duty frequency converter, for efficient and stable operation. The control components of the equipment are all made of Schneider Electric, which has a long service life and low failure rate. Through touch screen operation, users only need to easily input production data, and the equipment can automatically complete production requirements, achieving intelligent and automated production, reducing human operation errors, and improving production efficiency and product consistency. ​

Strict quality control：

We strictly follow the production quality standards of Taiwan’s cold-formed steel equipment and have established a professional testing laboratory. The laboratory is equipped with multifunctional testing machines such as Rockwell hardness tester, tachometer, roundness measuring instrument, coating thickness gauge, etc., to strictly inspect every aspect of equipment production, ensuring that every CU steel machine has excellent performance, process, accuracy, and quality. From design drawings to customized solutions, to equipment after-sales, all are handled by the same team of professional technicians, providing you with comprehensive technical support and guarantee. ​

Thoughtful after-sales service：

We are well aware of the importance of stable equipment operation for your production, and therefore provide 24/7 technical support and engineer services. No matter what problems you encounter during the use of the equipment, our professional team will respond quickly, solve your problems, and ensure the efficient production of your cold bending equipment without any worries. ​
