Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-tasking machine having multi-functions and, more particularly, to an energy-saving system for a multi-tasking machine which effectively utilizes only a necessary drive source when selectively machining a work.

[0002]

2. Description of the Related Art Conventionally, when a multi-function machine, for example, a multi-function including a laser processing function and a punching function is provided,
Despite the fact that laser processing and punching processing do not work at the same time, the energy required for combined processing has always been input. That is, when switching between laser processing and punching processing, the processing can be performed immediately, so that the laser oscillator is powered on even during punching processing and the punching processing drive motor is driven during laser processing. It was

Further, although the punching device and the laser cooling device (chiller or the like) are not used at the same time, a large type for both functions has been used.

[0004]

By the way, in such a composite processing machine, not only the main body of the processing machine becomes larger, but also its peripheral devices also become larger, and the power consumption tends to increase. In some cases, the effective use of the product may not be achieved and the user's willingness to install the equipment may be diminished. Therefore, reducing the initial cost and running cost was a major issue to be solved.

In order to solve the above problems, an object of the present invention is to provide an energy saving system for a multi-tasking machine in which the energy system is downsized and the power consumption is reduced and the energy can be effectively used. ..

[0006]

In order to achieve the above object, the present invention is a multi-tasking machine having a multi-function capable of coping with machining of a work, wherein a drive source required for driving the multi-function is It is an energy-saving system for a multi-tasking machine, which is selected and driven according to the machining of a workpiece.

[0007]

By adopting the energy-saving system of the multi-tasking machine of the present invention, the drive source required for driving the multi-function can be selected and driven according to the machining of the work, thereby reducing the size of the energy system. Low power consumption enables effective use of energy.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a system diagram showing an outline of an energy-saving system for a composite processing machine according to the present invention.

In the figure, a compound machine 1 comprises a punching press 3 represented by a hydraulic cylinder 7 and a laser machine 5 represented by a laser discharge tube 9. Further, the multi-tasking machine 1 has an energy system including a hydraulic pump 11 and a drive motor 13 for driving the oil pump 11, a solenoid switching valve 15 for supplying pressure oil of the hydraulic pump 11 from an oil tank 31 to the hydraulic cylinder 7, and A hydraulic system including a check valve 17, a cooling device 19, a cooling water switching valves 21 and 23, a cooling system including an oil cooler 25 and a discharge tube cooler 27, a drive motor 13, and a laser oscillation power source 29 for the laser discharge tube 9. A power supply system (not shown) for the cooling device 19 and the like is also provided.

The hydraulic pump 11 and the drive motor 13 are
The hydraulic pressure for punching is supplied to the hydraulic cylinder 7. Further, the check valve 17 is a prevention device that prevents the hydraulic cylinder 7 from dropping even though the hydraulic pump 11 and the drive motor 13 are stopped. The cooling device 19 is
Cooling water for cooling the oil temperature during punching or the temperature inside the discharge tube 9 that oscillates the laser power during laser processing is supplied. The cooling water switching valves 21 and 23 can freely switch the cooling water for punching processing or laser processing.

With this configuration, the hydraulic pump 11 and the drive motor 13 are driven during punching,
The switching valve 15 is operated, the pressure oil in the oil tank 31 is supplied to the hydraulic cylinder 7, and punching is repeated. At this time, the cooling water switching valves 21 and 23 are energized, the cooling water does not flow to the laser device side, and the cooling water is applied only to the hydraulic pressure cooling during punching.

At this time, the laser oscillating power supply 29 is not energized, or only the required current necessary for the base discharge that is ready for operation when switching to laser processing is energized.

During the laser processing, the hydraulic pump 11 and the drive motor 13 are stopped. At this time, the conventional hydraulic cylinder 7 may drop gradually, but it is processed by the check valve 17 to prevent the drop.
Further, the cooling water switching valves 21 and 23 are not energized, and the cooling water is supplied only to the laser processing side. When switching from laser processing to punching processing, the hydraulic motor 1
It is only necessary to start 3 and it is possible to operate immediately.

Therefore, the energy system of the present invention is an energy-saving type in which the necessary drive sources such as a power source, air, and cooling water system are selected and driven according to the machining of the work. The present invention is not limited to the above-described embodiment, but can be implemented in other modes by making appropriate design changes.
