Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser punch combined machine, and more particularly, to a method in which spatter does not scatter on the upper surface of a die and dross or spatter does not fall on the upper surface of a die during laser processing.
Further, the present invention relates to a laser punch combined machine that prevents spatter from scattering to peripheral devices.

[0002]

2. Description of the Related Art In general, a laser / punch compound machine is composed of a laser processing section and a punch processing section. For example, when a hole is drilled in a work, punch processing is performed, and when processing an outer shape of the work, laser processing is performed. High-speed and high-precision machining is performed by performing each process.

[0003] Among these, the punching section has an upper turret and a lower turret in which corresponding punches and dies are arranged in a ring shape, and the laser processing section has a processing head for irradiating a work with a laser beam.

In a laser / punch compound machine,
A clamp for gripping the work being processed is attached. The clamp is provided with a ball screw for moving the work in the X-axis direction and the Y-axis direction and an LM guide as a guide so that the work can be positioned. It has become.

[0005] Further, the punch center of the punching section constituting the laser-punch composite machine is very close to the laser center, for example, only 250 mm apart.

It is well known that in such a laser punch combined machine, when a processing head irradiates a work with a laser beam, spatters scatter from the work.

However, if the spatter scatters to the die of the adjacent punching portion or scatters to the positioning mechanism including the ball screw of the clamp and the LM guide, the functions of these peripheral devices are reduced and the processing efficiency is reduced. And other adverse effects.

[0008]

[Problems to be solved by the invention]

 (1) Spatter scatters on the upper surface of the die in the lower turret.

As described above, in the laser / punch combined machine, the punching part and the laser processing part are extremely close to each other, and the spatter scattered from the work during laser processing scatters on the die upper surface of the lower turret.

[0010] As a result, the height of the die changes due to sputtering, and when punching is performed, the height of the product is adversely affected.

(2) Dross and spatter fall on the upper surface of the die.

That is, as shown in FIG.
In the punch composite machine, a dross 35 and a sputter 36 are adhered to the back surface of the work W subjected to the laser processing by the processing head 32.

Therefore, in this state, when the work W enters between the upper turret 33 and the lower turret 34 constituting the punching section (arrow E in FIG. 5A), the friction between the work W and the die D is increased. As a result, the dross 35 and the sputter 36 fall on the upper surface of the die D.

The details are as shown in FIG. 5 (B). Dross and spatter 37 fall on the upper surface of the die D. Even if an attempt is made to perform a punching process, the accuracy of the product is significantly reduced.

In particular, this tendency is remarkable when the work W is formed by the punching portion or when the fine processing is performed.

(3) Spatter scatters to peripheral equipment.

As described above, in the laser-punch combined machine, an upper turret and a lower turret constituting an adjacent punching portion, a positioning mechanism including a ball screw of a clamp, an LM guide, and the like are provided around the laser processing portion. Is arranged.

However, if the spatter generated from the work scatters to these peripheral devices during the laser processing, the functions of the peripheral devices are reduced, and adverse effects such as a reduction in the processing accuracy of the product are caused.

For example, the surface of the ball screw is coated with grease, and is highly adhesive. Therefore, the spatter scattered from the work easily adheres to the ball screw,
The work cannot be accurately moved to a predetermined position, so that the positioning accuracy is reduced and the processing accuracy of the product is reduced.

An object of the present invention is to provide a laser punch combined machine in which spatter generated during laser processing does not scatter on the upper surface of the die, dross and spatter do not fall on the upper surface of the die, and spatter does not scatter on peripheral devices. Is to do.

As shown in the figure, in a similar laser punch multifunction machine,
Between the laser center LC and the punch center PC, in the vicinity of the lower turret 12, which constitutes the punching section,
A heat-resistant roll brush 6 is provided rotatably, sweeps dross and spatters 13 adhered to the back surface of the work W during laser processing, prevents dirt on the die D of the lower turret 12, and furthermore, as shown in FIG. In the same laser-punch combined machine, there is provided a sputter cover 22 which surrounds the processing head 2 and is movably mounted up and down, and covers the processing head 2 by lowering the sputter cover 22 during laser processing. Technical measures are taken to prevent spatter generated from the work from scattering to peripheral equipment.

Therefore, according to the configuration of the invention shown in FIG.
The spatter 5 generated during the laser processing does not scatter on the upper surface of the die D, and according to the configuration of the invention shown in FIG. 2, dross and spatter 13 do not fall on the upper surface of the die D. According to the method, the spatter does not scatter to the peripheral device.
