1. Loading horizontal material table
It consists of a material table bracket, a conveyor chain, a reduction motor, etc., which is used to transport the steel to the feed channel.
The loading horizontal material table is connected to the straightening machine purchased by the customer. When the customer orders the straightening machine, the straightening machine manufacturer should be required to reserve the installation interface.
2. Three-dimensional drilling feed channel
The three-dimensional drilling feed channel uses a power roller to connect to the straightening machine on the customer's site, accept the straightened profile, and automatically send it to the clamp position of the feeding trolley. The upper plane height of the roller in this scheme is 800mm from the ground. If the height of the straightening machine is different, the user should adjust it. The feeding channel is used to carry the workpiece to be processed. A photoelectric switch is installed at the front end of the channel to detect the front end of the workpiece and determine the processing reference in the X direction. The side push device presses the workpiece tightly and leans against the side positioning roller to achieve rough positioning of the workpiece in the Y direction.
3. Three-dimensional drilling feeding trolley
It is composed of gears, servo motors and manipulators. The manipulator has good rigidity and stability, can automatically rise and fall according to the profile specifications, and automatically clamp the workpiece. After the manipulator clamps the workpiece, it is driven by the servo motor. Under the transmission of the gear rack, the workpiece is fed in the X direction to ensure the longitudinal processing accuracy of the drilling.
4. Three-dimensional drilling host
The drilling host mainly consists of a base, a bed, a mobile slide, a spindle box, an upper pressing device, a side clamping device and a row tool magazine. The bed has good rigidity and stability, can withstand the load and vibration generated by high-speed processing, and ensure the accuracy of the machine tool.
There are 3 spindle boxes installed on the drilling host, namely the fixed side, the mobile side and the upper unit spindle box, which are used for horizontal and vertical drilling respectively. Each spindle box can be operated independently or complete drilling operations at the same time, which greatly improves production efficiency. Each spindle box has a set of BT40 high-speed mechanical spindles, and the corresponding row-type tool magazine can install up to 4 diameters of drill bits (when there is no tool on the spindle), and can automatically process 4 different hole diameters when the workpiece is clamped at one time. The spindle feed is driven by a servo motor, and fast forward, working forward, and fast reverse can be achieved through program control; the spindle motor is driven by a spindle servo motor, and the speed is steplessly adjusted with a wide speed regulation range.
The three spindle box units are hung on the bed side, and each spindle box unit is driven by two sets of servo motors to achieve horizontal and vertical movement of the spindle box, which is driven by a ball screw and guided by a precision linear rolling guide. This equipment presses the workpiece in two directions during the drilling process. There is a cylinder-driven pressing mechanism above the workpiece to press the workpiece against the horizontal support roller, and there is a cylinder-driven pressing mechanism on the side to press the workpiece from the side.
5. 3D drilling discharge channel
It is composed of a reducer, a channel support, a support roller, a side positioning roller, a chain, etc. The sawing discharge channel is used to carry the workpiece after sawing. The reducer drives the support roller to drive the workpiece to move along the X direction.
6. Typing device: Mark the workpiece
7. Cooling system: The spindle internal cooling method is used to cool the drill bit, and an external cooling device is also equipped.
8. Hydraulic system: It is used to provide power for workpiece pressing and typing device.
9. Pneumatic system: It is used to provide power for side push device, spindle blowing, etc.
10. Lubrication system
It adopts a combination of centralized lubrication and manual lubrication. A centralized lubrication device is used to lubricate certain linear guides and lead screws at a fixed time and quantity, and manual lubrication is used for other lubrication points.
11. Electrical system
The control system of the production line is composed of a host computer, PLC, etc. Programming method: Input CAD drawings or processing parameters through the USB interface or keyboard to generate processing programs. The processing program can be stored, called, displayed and communicated at any time according to the part number. The production line can realize both manual adjustment and control of each processing parameter separately and automatic control of the whole process.
During sample demonstration sessions, the CNC beam plate metal drilling, marking, and shearing machine effectively showcases its processing capabilities with standard H-beam samples (featuring various flange widths and web thicknesses) as well as channel steel samples of different sizes. The samples used in these demonstrations clearly highlight the machine’s ability to deliver precise hole placement, smooth threaded tapping, and distinct marking patterns, thereby thoroughly demonstrating its high accuracy and dependability in practical applications.
The High-Speed CNC H-Beam Drilling, Marking, and Shearing Machine is primarily utilized in steel structure fabrication workshops and bridge construction projects. In steel structure fabrication, it performs precise processing on H-beams used in framework and support structures, providing a solid foundation for the stable assembly of steel frameworks. In bridge construction, it executes high-precision drilling operations on H-beams, enhancing the structural integrity of bridges and ensuring their ability to withstand long-term loads. With its outstanding operational efficiency, the machine consistently supports these vital infrastructure sectors, facilitating the seamless progression of related projects.
