In the modern steel door manufacturing industry, the composite production program of roll rolling and bending machine (roll bending program) has gradually become a new trend in the industry by virtue of its flexibility and high efficiency. This solution completes the continuous standardized forming of the lace section of the main body of the door frame through the roll rolling process, and at the same time combines with the CNC bending machine to accurately process the angle of the shaped bending section (such as reinforcement, decorative edges, locks, etc.), which is not only adaptable to the diversified needs of the size of the door frame of the burglary-proof door, fire prevention door, purification door, and so on, but also highly efficient in dealing with the complex design of the cross-section, which significantly reduces the dependence on the special tooling.

Compared with the traditional roll-rolling single machine, the roll-bending solution significantly optimizes the cost through segmented processing - the roll-rolling section ensures the high efficiency and stability of the main body molding (speed up to 20m/min), while the bending section realizes the flexible adjustment of non-standard structure, which not only retains the independence of the process (the failure of a single machine does not affect the overall production), but also reduces the investment in molds by more than 40%. Mold input.

In the production process, the coil is extruded by roll rolling one by one, and then accurately positioned by the servo system to the bending station, and the accuracy is controlled by the angle feedback and rebound compensation technology (±0.5°), and the integration of the flying shear cutting and preform splicing interface technology, which can synchronously complete the fixed-length cutting and seamless docking. For special process requirements, online integration of multi-station punching and chopping module can also be directly completed hinge holes, lock holes and 45 ° interface processing, further eliminating the secondary clamping error, so that the comprehensive material utilization rate increased to 98%. This solution guarantees product quality (double closed-loop inspection system) while achieving an efficient balance between standardization and customization, especially suitable for flexible production scenarios of small to medium batches and multiple categories.
