What are the working principles and characteristics of hydraulic drilling machine?

Hydraulic Drilling (HydraulicDrilling) commonly known as hydraulic drilling machine, multi-axis drilling machine, multi-hole drilling machine, is a new type of high-efficiency hole processing equipment. An ordinary multi-axis drilling machine with a hydraulic drilling machine can be a one-time several or even dozens and dozens of holes processed out. The drilling machine can automatically back chip, fast forward, work in (work back), fast back, stop. It can quickly drill, ream, ream, chamfer, countersink flat surfaces and repair and scrape end faces and other forms of processing. According to the structure classification of the equipment, hydraulic drilling machine can be divided into table-type hydraulic drilling machine, vertical hydraulic drilling machine, horizontal special drilling machine and so on. Among all kinds of drilling machines, hydraulic drilling machine has high processing precision, fast efficiency, easy operation, can effectively save the investor's manpower, material and financial resources, wide range of application, has become a model of high-precision machining industry, especially suitable for single piece or mass production of holes with multiple holes with the hole machining of parts, is the first choice of mass production of machining shop machine tools.

Operating Principle of Hydraulic Drilling Machine:

1, Hydraulic automatic feed drilling head: the spindle rotation is driven by the motor through the belt, pulley, spline vice spindle to realize the rotation.

2, feed movement: the original power is provided by the hydraulic station, through the spindle within the cylinder mechanism and speed control valve to realize the conversion of fast forward, work in.

3, work into the speed adjustment: through the adjustment of the speed control valve knob to realize the work into the speed change.

4, drilling depth adjustment: the machine is equipped with upper limit position, lower limit position travel switch, adjust the lower limit position travel switch to adjust the drilling depth, the upper limit position travel switch for the spindle reset position, fast-forward and work-forward changeover position adjustment, through the adjustment of the speed valve block to adjust the fast-forward, work-forward changeover position.

Main features of hydraulic drilling machine:

1, the spindle system adopts the same structure as the principle of the power head, and the spindle is directly pushed by hydraulic pressure to carry out the up and down feeding movement, which has the advantages of transmitting large torque and accurately than that of the traditional pneumatic table drills indirectly pushed by the air cylinder.

2, the electronic control system adopts advanced integrated circuit control, the key electrical components of the French brand Schneider and Taiwan brand TENDER, with stable and reliable control, long service life and other characteristics.

3, hydraulic system are used in Taiwan brand variable vane pump, with stable operation, low noise, low temperature rise. Independent cooling system, equipped with cooling pump motor and mobile water tank can automatically provide coolant, with overload protection device, protection of phase failure to burn the motor link and overload signal indication circuit.

4, can be configured according to customer needs of various types of multi-axis drilling and various types of air-hydraulic fixture.

5, according to customer needs can be added peck drilling function, can easily realize deep hole processing.
