Three-dimensional drilling is mainly used for steel structure, three-dimensional garage, construction, bridge and other industries of H steel drilling. According to the different forms of the results, the three-dimensional drill can be divided into the trolley feed three-dimensional drill bit and the gantry mobile three-dimensional drill bit. Today, the small series mainly introduces three-dimensional drilling, which is mainly used for processing large tonnage H-beam.

Three-dimensional drilling is mainly used for steel structure, three-dimensional garage, construction, bridge and other industries of H steel drilling. Depending on the form of the result,three-dimensional drillIt can be divided into three-dimensional drill bit and gantry mobile three-dimensional drill bit. Today, the small series mainly introduces three-dimensional drilling, which is mainly used for processing large tonnage H-beam. The mobile gantry three-dimensional drilling machine is mainly used for three-dimensional drilling of large H-shaped steel or box girder. The workpiece is fixed by mobile gantry, which has the characteristics of high processing efficiency and stable precision, and can be widely used in construction, bridge, tower and other industries.

1. gantry type CNC three-dimensional drill structure features:

1. The gantry mobile three-dimensional drilling machine is mainly composed of bed, gantry, spindle box, electrical control system, hydraulic system, cooling chip removal system, detection system, etc.

2. The gantry mobile three-dimensional drilling machine adopts the form of gantry mobile fixed worktable, which can reduce the length of the bed and save the floor space.

3. The frame movement (X axis) is guided by linear roller guide rail and driven by AC servo motor and low backlash rack and pinion pair. The movement of the gantry beam and the sliding plate on the two uprights (U, V, W) is guided by linear ball guides and driven by AC servo motors and screws. The feed movement of each drill bit (axis 1, 2 and 3) is guided by a linear ball guide and driven by an AC servo motor and a screw.

4. The spindle box adopts the CNC feed drilling power head produced by our company.

5. The lower part of the gantry mobile three-dimensional drilling rig is equipped with a flat chain chip remover, and the flat chain slag remover is equipped with a water pump and a coolant filter circulation device.

6. The hydraulic system is mainly used for the positioning and locking of the X axis and the balance of the power heads on both sides.

7. Controlled by PLC, equipped with upper computer. It can input and store workpieces through a computer, and the operation is simple.

2.three-dimensional drillOperation specification:

1. Read the operation manual carefully and conduct professional training before operation.

2. Before operation, check whether there are people and obstacles in the machine and conveyor, and if found, clean them immediately.

3. The operator should select the appropriate drill bit according to the drawing requirements and check the sharpness of the optional drill bit. If you are slow, you should practice.

4. Turn on the power, turn on the control power and air source, check whether the indicator light is working properly, whether the pipeline is leaking, whether the wing clamping device is working properly, and whether the rotation of each drill shaft is normal.

5. When replacing the drill, stop the operation of all parts of the machine.

6. When processing parts, procedures should be compiled and carefully checked, and the parts to be processed should be re-checked. Only after the correct re-inspection, the parts can be formally processed.

7. Check whether the coolant circulation pump is working properly at any time.

8. At the end of each shift, turn off the computer, then cut off the power supply, clean the operating platform and equipment, and add oil to prevent rust.

Advantages of 3. 3D drill:

1. The machine tool adopts the structure of fixed bed and movable workpiece, and the bed is welded by steel plates with sufficient strength. The 3D drill of this structure is suitable for the processing of small and medium-sized H-shaped steel, which is convenient for continuous production and has a high degree of automation.

2. Each drilling headstock of the CNC 3D drilling machine is hydraulically controlled. It can automatically switch from fast forward to fast forward without manually setting the effective length of the drill bit and the thickness of the workpiece to be drilled.

3. 3D drill can realize the direct conversion of CAD/CAM, eliminating the tedious operation of programming and input. Automatic generation of processing procedures, the real realization of paperless processing equipment.

4. 3D drilling machine body for high quality steel welding frame structure. Through finite element analysis and calculation, the square steel pipe is strengthened in the place with large stress, and the thermal aging treatment is carried out after welding, which greatly improves the static and dynamic characteristics of the machine body, thus ensuring the accuracy of the whole machine.

5. Ball screw pair, linear guide pair, electrical components, servo motor, frequency converter, etc. The machine tool configuration is provided by well-known manufacturers at home and abroad, with few startup failures.
