Main Technical Parameters of The Machine Tool

Horizontal CNC boiler barrel drilling machine It is mainly used in the boiler industry to use high-speed steel twist drills to drill pipe holes on the set-up pipes, and special high-speed steel combination drill boring tools can be used to complete the welding groove processing. Instead of manual marking, the position accuracy and drilling efficiency of the hole are greatly improved, and drilling is automated.

 

Machine structure features

1. The machine tool is composed of a base, a gantry, a numerical control indexing head, a drilling head, a vertical slide table, a header support frame, a clamping pressure cylinder, a chip removal and cooling, an automatic lubrication, a hydraulic system, a pneumatic system, and an electrical system.

2. The base is the basic part of the machine. The welded steel structure is treated with thermal aging stress to have good rigidity and stability. The bottom of the base is covered with a number of adjustable foundation screws, which can be easily adjusted to ensure the flatness and straightness of the guide surface on the base.

3. The gantry adopts welded frame structure. Longitudinal movement of the gantry (X-axis) adopts two high-capacity 65-row linear roller guides that are fixed on the pedestal. The drive adopts AC servo motor via precision reducer and anti-backlash rack and pinion pair. It is equipped with a hydraulic locking slider, which locks the slider when the drive motor stops, enabling the gantry to lock on the base. Ensure high X-axis positioning accuracy and quick positioning.

4. The CNC indexing head is fixed at one end of the machine base. With precision slewing bearings, AC servo motors achieve numerical control indexing through precision planetary reducers. The three-jaw self-centering chuck is installed on the dividing head, which can easily clamp and release the workpiece and reduce the labor intensity of workers.

5. Drilling head and vertical slide

The drilling head is driven by a variable frequency motor via a gearbox to drive the drilling spindle. The vertical slide uses a linear roller guide guide, and the vertical feed is driven by an AC servo motor to achieve fast forward/work in/out (delayed)/reverse action.

The head of the drilling head spindle is Moser No. 5, which can directly install various diameters of high-speed steel twist drills, or special combination drilling tools

6.Set box support frame

There are two kinds of support frames, two support frames at the two ends, and three intermediate support frames. The two ends of the support frame are equipped with two rollers for supporting the outer surface of the header pipe to adapt to different diameters of the header pipe. Firstly, the rollers on the support frame are installed at different positions, and secondly, the support frame can be supported. The height is adjusted (hand screw jack elevator) and can be locked after adjustment. The difference between the middle support frame and the two end support frames is that the support frame can swing to adapt to the bending and ellipse of the tank set. The longitudinal movement of the two support frames is rolling friction.

7.Pressure cylinder

When the gantry is moved to the drilling position, the clamping pressure cylinder can press the collecting tank to reduce the vibration during the drilling process. The clamp pressure is adjustable (hydraulic pressure).

8.Chip removal and cooling

A plate-shaped chain chip remover is installed in the trench below the base, and the chips can be automatically discharged into the tail-end chip conveyor to achieve a civilized production. A cooling pump is provided in the coolant tank of the chip conveyor to cool the tool externally to ensure the drilling performance and service life of the drill. The coolant can be recycled.

9. Automatic lubrication

This type of box drill is equipped with automatic lubrication device, which can automatically lubricate the guide rail pair, gear pair, rack and pinion pair.

10. Advanced electrical control, using FAGOR8055 CNC system and host computer management, greatly facilitate the storage, call, display, diagnosis and operation, to achieve the drilling process automation, workpiece CAD drawings can be directly input, automatic programming.

11. The key mechanical, hydraulic and electrical components of this type of box drill configuration, such as linear roller guide pair, precision speed reducer, rack and pinion pair, hydraulic pump, valve, servo motor and driver, numerical control system, etc. are mostly well-known foreign manufacturers. Products, so the machine's accuracy and reliability, low failure, high operating rate.
