2D Wire Bending Machine: Precision Forming Solution for Metal Frames of Automotive Sunshades

In the field of automotive parts manufacturing, sunshades, as key accessories to enhance driving comfort, the forming precision and production efficiency of their metal frames directly affect the quality of the vehicle's interior. The 2D wire bending machine, with its performance parameters customized for the automotive industry's needs, has become the core equipment for processing metal frames of sunshades. It not only meets the stringent requirements of the automotive manufacturing industry for standardized production but also supports diversified design needs through flexible process adaptability, injecting technical momentum that combines efficiency and precision into sunshade production enterprises.

The large-scale nature of automotive parts production places strict requirements on the production efficiency of equipment. The 2D wire bending machine, with a basic production speed of 8-10 pieces per minute, easily handles the mass processing of conventional sunshade frames; for square frame structures of 200*200mm specifications, the efficiency can be further increased to 12-15 pieces per minute, equivalent to a maximum output of 900 products per hour, perfectly matching the fast-paced production needs of the automotive industry chain.

Behind this high efficiency is the precise collaboration between the 4-axis drive system and servo motors. The equipment is equipped with domestic Orui servo motors with a total power of 7.3kw, including a 1.8kw wire feeding servo to ensure stable wire conveying, a 1.5kw bending servo to provide strong bending power, a 1.0kw cutter servo for sharp cutting, and a 1.0kw lifting servo to control precise displacement of the mold. The scientific power distribution of each component, combined with a wire feeding speed of 22m/min and a maximum bending speed of 300 rpm, enables the processes of feeding, straightening, bending, and cutting to be completed in one go, significantly shortening the processing cycle of a single product.

The assembly accuracy of automotive parts is measured in millimeters. Dimensional deviations in sunshade frames may lead to problems such as installation jams and abnormal noises. The 2D wire bending machine achieves high-precision control through multiple technical means: both bending accuracy and wire feeding accuracy are stable within ±0.5mm, ensuring the symmetry and hole position matching of the frame; 18 sets of straightening wheels made of national standard Cr12 eliminate wire stress through multi-stage correction, laying a flat foundation for subsequent forming.

The selection of core components of the equipment further highlights the ultimate pursuit of precision. The bending mold is made of high-quality SKD11/51 materials, with a hardness of 58-62° after precision processing, maintaining shape stability during high-frequency bending operations and avoiding dimensional drift caused by mold wear; 3 sets of wire feeding wheels are made of national standard Cr1MOV, with excellent wear resistance after precision polishing and heat treatment, maintaining stable wire feeding accuracy even after long-term use. This quality control over key components ensures the consistency of the equipment in continuous production and reduces the rejection rate caused by dimensional deviations.

Automotive sunshades need to present different curvatures and structures according to vehicle design, and the flexible adaptability of the 2D wire bending machine provides strong support for this. The equipment supports the processing of 3-8mm iron wires and can handle various wire forms such as round wires, flat wires, and square wires. Whether it is the frame of the sunshade or the internal support structure, it can be precisely formed. The bending angle covers a range of ±180°, and with the up and down movement of the inner and outer molds and the 360° forward and reverse rotation function of the outer mold, it can complete complex shapes such as U-shaped, L-shaped, and wavy shapes, meeting the personalized design needs of different vehicle models.

The intelligence of motion control further enhances process flexibility. The equipment is equipped with a 32-bit high-performance processor, which controls all mechanical actions through microcomputer programming. Each program can set 300 actions and supports a total of 4000 sets of data storage. When it is necessary to switch vehicle models or adjust designs, operators only need to call the corresponding program without repeated debugging, greatly shortening the production change time. The Chinese-English bilingual system and program upload and download functions facilitate multi-equipment collaborative production and parameter standardization management, adapting to the standardization requirements of automotive parts production.

The trend of intelligent upgrading in the automotive manufacturing industry requires production equipment to have a high degree of automation. The 2D wire bending machine integrates full-process automated functions such as automatic feeding, automatic unloading, straightening and cutting, and bending forming. From wire loading to finished product output, no manual intervention is required, which not only reduces labor costs but also avoids precision errors caused by manual operations.

The auxiliary system of the equipment also provides guarantees for automated production: the electrical configuration of three-phase 380V + grounding wire ensures safe and stable operation; the pneumatic system composed of 1 cylinder and 1 solenoid valve provides precise power for mold displacement; the touch screen + button dual-mode control panel makes operation intuitive and convenient, even complex parameter settings can be completed quickly. This highly integrated automated design enables the equipment to be easily integrated into the automation system of the automotive parts production line, achieving seamless connection with upstream and downstream processes.

In the field of automotive sunshade production, the 2D wire bending machine, with the triple advantages of "high-efficiency mass production + precision forming + flexible adaptation", has become a key link connecting design creativity and industrial production. Its stable 850kg body not only ensures processing stability but also saves workshop layout space; the bending angle accuracy of ±1° and long-lasting wear resistance provide reliable guarantees for long-term stable production.

For automotive sunshade enterprises pursuing quality and efficiency, this equipment is not only an upgrade of production tools but also a strategic choice to enhance product competitiveness. In the metal bending within a small space, it interprets the eternal pursuit of "precision" and "efficiency" in the automotive manufacturing industry.
