It adopts an integral high-quality steel plate welded structure with a heavy-duty and high-rigidity frame. The machine surface is coated with imported anti-rust primer and topcoat, keeping the equipment in good condition permanently. The machine tool is mainly composed of the frame, upper slide, backgauge system, slide block and synchronous control device, dies, hydraulic system, control system and other components. Product detail display Frame Section It adopts a frame-type structure, consisting of worktable vertical plates, left and right side plates, and connecting beams. It is integrally welded with steel plates, featuring high rigidity, high strength and excellent resistance to torsional deformation. Internal stress is eliminated through processes such as surface shot blasting, ensuring long-term stability of the overall machine precision. During bending, the deformation of the upper slide and worktable is minimal, which guarantees excellent straightness and angular consistency of workpieces. Die and Clamping Device It is composed of upper and lower dies, featuring high precision, premium quality and long service life. The upper die is mounted on the slide block, securely fixed by a precision quick-release clamping device. The lower die adopts a dual-V concentric design, allowing for fast and convenient die changeover, effectively reducing operator labor intensity, and significantly improving overall production efficiency.device. The lower die adopts dual V concentric design, enabling fast and convenient die change, reducing intensity and improving efficiency. Codpfx Aijy Uc Nkoasgu Throat Opening Deflection Compensation Device A linear encoder is installed on each side of the machine to measure and feed back the precise distance between the slide block and the lower worktable. The encoders are connected to the worktable via C-frames, effectively eliminating the influence of frame throat deformation on the slide block position. Position data is fed back to the CNC system, which outputs signals to control the hydraulic proportional servo valves, ensuring accurate synchronization of the two cylinders. Backgauge System Adopts the latest Belgian-designed backgauge for exceptional precision and stability. Driven by servo motors and ball screws, it delivers high speed and outstanding positioning accuracy. The unique dual linear guide rail structure ensures excellent long-term repeatability. Multi-stage positioning expands the working range, offering superior value for investment. Modular design allows axis configuration from single-axis X to multi-axis options. Mechanical Compensation Device Adopts an integrated mechanical compensation wedge block, motor-driven for precise adjustment. It automatically fine-tunes the worktable alignment, offsetting deflection caused by bending forces. The system ensures consistent precision along the entire length of the workpiece. It provides reliable, repeatable adjustment, eliminating the need for manual correction, and significantly improving bending accuracy.
