Product Features
1. This 3D H-beam drilling and cutting machine primarily consists of the main machine frame, CNC feeding system, material conveyor, electrical system, hydraulic system, cooling system, lubrication system, waste container, and other related components. Featuring a fixed bed design and a movable workpiece configuration, the machine is ideally suited for processing large H-beams. It supports continuous production operations and is widely recognized for its high level of automation.
2. The structure of the drilling machine includes the bed, CNC sliding table assemblies, support structures, upper pressing units, side pressing units, and detection systems. The CNC sliding table assemblies consist of the fixed side, movable side, and the upper-unit CNC sliding table. Specifically designed for H-beam drilling applications, the sliding table components feature a sliding plate, sliding table base, spindle headstock, high-speed mechanical spindle, tool cylinder, variable-frequency motor, servo motor, linear guides, and lead screws.
3. The CNC feeding system comprises brackets, gears, racks, servo motors, reducers, and manipulators. The servo motor drives the manipulator, facilitating the movement of the H-beam along the X-axis, thereby ensuring precise feeding and accurate positioning of the workpiece.
4. The material conveyor consists of both an in-feed conveyor and an out-feed conveyor. The in-feed conveyor includes conveyor brackets, support rollers, and side-pushing mechanisms, all designed to transport profiled steel blanks, achieve Y-axis positioning of the blanks, and work in tandem with the CNC feeding system to streamline the material feeding process. The out-feed conveyor, consisting of material channel brackets and support rollers, is specifically designed for the transportation of finished workpieces.
5. The cooling system utilizes both internal and external cooling methods, employing oil mist to cool the borehole. This approach offers numerous advantages, including reduced coolant consumption, which improves cost efficiency, promotes environmental sustainability, and minimizes wear on the drill bit.
6. The hydraulic system supplies power to the upper pressing unit, side pressing unit, tool cylinder, and other associated components.
7. The pneumatic system is designed to power the manipulator, testing cylinder, and other similar equipment.
8. The lubrication system employs both centralized and manual lubrication methods. Centralized lubrication is primarily used to ensure the timely and precise lubrication of the main linear guides and lead screws.
9. The machine tool's control system consists of a host computer, PLC, and other related components. Programming Method: Processing programs are created by inputting CAD drawings or processing parameters via a USB interface or keyboard. These programs can be stored, retrieved, displayed, and transmitted at any time using part numbers. The machine tool allows for manual adjustment and control of individual processing parameters, while also supporting full automation of the entire processing sequence.
During sample demonstration sessions, the CNC beam and sheet metal drilling, marking, and shearing machine effectively demonstrates its processing capabilities when working with standard H-beam samples—featuring varying flange widths and web thicknesses—as well as channel steel samples of different sizes. The specimens showcased in these demonstrations clearly highlight the equipment's ability to achieve precise hole placement, clean tapped threads, and well-defined marking patterns, thereby thoroughly illustrating its exceptional accuracy and reliability in real-world applications.
The High-Speed CNC H-Beam Drilling, Marking, and Shearing Machine is primarily utilized in steel structure manufacturing facilities and bridge construction projects. In steel structure workshops, it ensures precise machining of H-beams used in frameworks and support structures, providing a strong foundation for the stable assembly of steel constructions. In bridge construction, the equipment performs high-precision drilling operations on H-beams, improving the structural integrity of bridges and enabling them to effectively withstand long-term loads. With its exceptional operational efficiency, this machine offers reliable support for these essential infrastructure sectors, contributing to the smooth progress of related projects.
