Abstract

PURPOSE:To reduce the height of a machine by disposing a machining head in a position of the same height as a punch head in the horizontal direction, and reducing the amount of offset, the machining head being mounted on a laser head. CONSTITUTION:A punch head 17 and a die head, which are provided opposite to each other on both sides of a work, are moved synchronously with each other along the vertical direction, e.g. the Y-axis, and then a punch P mounted on the punch head 17 and a die mounted on the die head are moved in collaboration with each other along the horizontal direction, e.g. the Z-axis, so that the work being held in the vertical direction is punched. To subject the work to laser beam machining, a laser beam is emitted toward the work from the machining head 69 of a laser head 41 provided adjacent the horizontal side of the punch head 17, whereby the laser beam machining for the work is carried out.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-tasking machine capable of punching and laser-working a work while holding the work vertically.

[0002]

2. Description of the Related Art Recently, while holding a work in a vertical direction, the work is moved in one direction, for example, in a horizontal direction, and a punch head and a die head provided on opposite sides of the work are synchronized with each other. By moving the punch mounted on the punch head and the die mounted on the die head in the other direction in the horizontal direction in parallel with the vertical movement of the punch. A vertical punch press is considered.

Since laser processing is required for trimming and the like after forming a work on a work with this vertical punch press, it is necessary to attach a laser oscillator to the vertical punch press to consider it as a combined machine.

[0004]

When a laser oscillator is attached to the vertical punch press to consider a multi-tasking machine,
Since the laser optical path system is equipped with precision parts such as mirrors, it is extremely reluctant to vibrate, and if punching is performed while it is combined with the punch head that is the vibration source, for example, the alignment of the mirror may be misaligned. .

Further, in the case of a vertical punch press, if the laser head is arranged in the vertical direction of the punch head, the height direction of the machine becomes high, which may give an operator an intimidating feeling.

Further, if there is an offset amount between the laser head and the punch head, there is a drawback that the movement amount of the work table increases by the offset amount and the size of the machine becomes large.

In view of the above-mentioned drawbacks, an object of the present invention is to keep the punch head and the laser head at substantially the same height, to keep the height of the machine low, to reduce the offset amount, and in the laser processing machine during punching. An object of the present invention is to provide a composite processing machine that does not give vibration to an optical system such as a mirror.

[0008]

In order to achieve the above object, according to the present invention, a carriage holding a work in a vertical direction is provided movably in one direction in a horizontal direction, and is opposed to each other on both sides of the work. A vertical punch that vertically moves a punch head and a die head, and moves the punch mounted on the punch head and the die mounted on the die head in the other horizontal direction to punch the workpiece. A laser head having a processing head, which comprises a press and is adjacent to the side of the punch head in the horizontal direction and which performs laser processing on the work, is provided, and the processing head is provided independently of the punch head in the other horizontal direction. It was installed so as to be freely movable to form a multi-tasking machine.

In the multi-tasking machine, the laser head is provided with a positioning device having a positioning member movable in both directions, and a lock member for fixing the positioning member by the movement of the positioning member is provided with the punch head, the processing head. It is desirable to be provided in each.

[0010]

By using the multi-tasking machine of this invention,
Hold the work vertically on the carriage. The carriage holding the work in the vertical direction is moved in one direction in the horizontal direction, for example, the X-axis direction. The punch head and the die head, which are provided on opposite sides of the workpiece, are moved in synchronization with each other in the vertical direction, for example, the Y-axis direction, and the punch mounted on the punch head and the die mounted on the die head are horizontally moved. In the other direction, for example, in the Z-axis direction, the work held in the vertical direction is punched by moving the work in cooperation with the other direction.

In the case of performing laser processing on the work, the work is laser-processed by irradiating the work with a laser beam from a processing head of a laser head provided adjacent to a horizontal side of the punch head. Is performed.

When the punching process is performed, the positioning head of the laser head is locked by the positioning member of the positioning device to the locking member of the processing head so that the processing head is separated from the punch head. Further, when performing the laser processing, the positioning member of the positioning device provided on the laser processing head is locked to the lock member provided on the punch head, and the processing head is integrated with the punch head.

It can be suppressed without increasing the machine height.

The present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes.

[0039]

As can be understood from the above description of the embodiments, according to the present invention, since the structure is as described in the claims, the punch head is mounted on the laser head. Since the machining heads are arranged at the same height apart from each other in the horizontal direction and the offset amount is reduced, it is possible to suppress the height of the machine without increasing it.

Further, during the punching process, vibration is not applied to the processing head of the laser head, so that damage to the optical components such as the mirror and misalignment of the mirror can be prevented.
