PP103B
The CNC hydraulic flat punching machine is engineered specifically for the rigorous demands of processing small and medium-sized metal plates. It serves as a critical asset in industries requiring exact metal fabrication, including steel structure construction, electric power tower manufacturing, and heavy automobile assembly. By securing the workpiece with a single, firm clamping action, the equipment ensures strict positional accuracy for every punched hole, eliminating the shifting and misalignment often associated with manual repositioning.
Operators will notice the immediate operational efficiency, as the automated feeding and punching cycle replaces labor-intensive traditional methods. The machine is perfectly adapted for creating precise connection plates, node plates, and base plates. Through its automated workflow, it addresses the core manufacturing challenges of maintaining consistent hole tolerances across large production runs, ultimately accelerating the assembly process on the final construction or production line.
Equipped with three distinct die positions, the system allows operators to install three sets of dies simultaneously. This configuration punches holes of three different diameters on a single workpiece without stopping to retool. Alternatively, the setup can hold two sets of dies alongside one character box, enabling dual-diameter punching combined with clear, deep-pressed character printing. The physical die replacement process is straightforward, ensuring minimal downtime, while the pressed characters remain highly legible even after subsequent galvanizing or painting.
The foundation of this heavy-duty machine tool relies on a premium steel plate welding structure. Following the welding process, the entire surface undergoes a thorough painting treatment. This meticulous finish not only provides a smooth, industrial-grade tactile feel but significantly enhances the surface quality and anti-rust capabilities of the steel plate, ensuring structural integrity over years of continuous vibration and impact.
Operating on two primary CNC axes, the machine controls the X-axis for the left and right movement of the clamp, and the Y-axis for the front and back movement. The highly rigid CNC workbench anchors this motion, guaranteeing the reliability and exact accuracy of the material feeding process, even when handling thick, heavy metal plates.
To maintain smooth mechanical operation, the machine tool is lubricated through an intelligent combination of centralized and decentralized lubrication systems. This dual approach ensures that every critical moving component, from guide rails to ball screws, receives the exact amount of oil required, keeping the machine tool in optimal working condition during every shift.
The NC worktable responsible for moving the workpiece is securely fixed directly onto the foundation. It features a surface embedded with universal conveying balls. As heavy steel plates glide across these metal spheres, the physical resistance is drastically reduced. This design results in notably low noise levels during operation and simplifies routine maintenance tasks.
Material security is handled by two powerful hydraulic clamps that grip the metal firmly. This robust clamping force prevents any micro-shifting during the punching impact, allowing the workpiece to be moved and positioned rapidly and accurately across the worktable.
The internal pumps, valves, and fluid control parts of the hydraulic system are sourced from globally recognized brand products. This careful selection creates a hydraulic power system that is compact in structure yet incredibly firm and durable. It delivers stable stamping force and sufficient power reserves, ensuring the dynamic performance of the machine tool while maximizing long-term reliability.
The primary computer interface utilizes an accessible English menu, designed specifically so that general operators can master it with minimal training. Programming is straightforward: the screen clearly displays the workpiece graphics alongside the exact coordinate sizes of the hole positions for easy visual verification. Furthermore, engineering files can be converted from CAD graphics directly into DXF format and imported straight into the processing program. The upper computer management system greatly facilitates the organized storage and instant recall of previous production programs.
