Description

[Detailed description of the invention] [Industrial application field] The present invention is a punching/thermal cutting composite processing comprising a punching section that performs punching on a workpiece and a thermal cutting section that performs thermal cutting. The present invention relates to a multi-tasking machine, and more particularly to a multi-tasking machine that prevents spatter generated in a thermal cutting section from adversely affecting punches, dies, etc. in a punching section.

[Technical background of the invention and its problems]

Conventionally, in multi-tasking machines equipped with, for example, a punching section and a thermal cutting section using plasma or laser, the molten metal powder generated during the thermal cutting process passes through a duct installed at the bottom of the workpiece to form dust. Boxes were collected.

On the other hand, it has generally been the case that no dust collection mechanism is provided between the punching section and the thermal cutting section above the workpiece.

However, there is a problem in that spatter and fume are generated above the workpiece during thermal cutting, and the spatter and fume scatter and damage the adjacent punching die or die holder.

The present invention was developed in view of the conventional problems mentioned above, and its purpose is to prevent fumes, spatter, etc. generated in the thermal cutting process from entering the punching process. The goal is to provide opportunities.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a punching/thermal cutting composite processing comprising a punching section that performs punching on a workpiece, and a thermal cutting section that performs thermal cutting on the workpiece. In the machine, a partitioning member for partitioning the punching processing part and the thermal cutting processing part is provided between the punching processing part and the thermal cutting processing part. A spout is provided on the upper surface of the workpiece to blow air diagonally downward, and the air jetted from the spout to the upper surface of the workpiece is disposed on the side surface of the partition member on the side facing the thermal cutting section. It is equipped with a dust collection section equipped with an inlet for inhalation.

[Function] By adopting the present invention, the direction of scattering of spatter or fume generated by thermal cutting,
The directions of the air flowing out from the air jet ports provided at the lower part of the partitioning member are opposite to each other, and collide with each other to form a mixed flow. Further, the turbulent flow collides with the turbulent flow wall provided at the dust collection port, and the turbulent flow is forcibly discharged from the dust collection port to the outside of the machine, so that fume or spatter can be reliably removed.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Referring to FIG. 1, for example, in a punch press 1 equipped with a laser cutting machine, which is a punching-thermal cutting composite processing machine, a mold holder 3 includes a plurality of punches 5.
The die holder 7 is equipped with a die 9 corresponding to the punch 5. The striking element 11 is positioned over a desired punch 5 among the plurality of punches 5 by a drive motor and a timing belt (both not shown). A laser processing head 13 including a nozzle lens and the like is attached to the machine frame 15 next to the punch 5 and die 9.

During punching or laser cutting, the material is held by the material clamp 17. Material clamp 1
The carriage 19 includes a drive motor 21x such as a servo motor and a pole screw 23x.
The carriage base 25 including the carriage 19 is moved in the Y-axis direction by the drive motor 21y and the ball screw 23y, and this two-dimensional movement in 5. A desired set of punches 5 and dies 9 are positioned between the punches 5 and the dies 9, or directly below the laser processing head 13.

Laser light emitted from the laser oscillator 27 is guided through an optical path 29 and reaches the laser processing head 13. Molten metal released during laser machining is collected in a dust box 33 through a duct 31, and products separated from the material are discharged out of the punch press 1 with laser cutting machine through a product shooter 35.

Furthermore, the punch 5 and the laser processing head 13
A partitioning member 37 hanging down from the machine frame 15 is attached between the punch press 1 and the punch press 1 with a laser cutting machine.

The partitioning member 37 separates a punching section where punching is performed using the punch 5 and die 9, and a thermal cutting section where thermal cutting is performed using the laser processing head 13. This partition member 37 is provided with an air flow port 43, and although not shown, a hose 4 is connected to a compressed air supply source outside the machine.
Compressed air is supplied to the air flow port 43 by the air outlet 1 and the like. A jet port 45 is formed at the lower end of the air flow port 43 and is inclined toward the laser processing nozzle 39 . Further, a dust collecting section 47 is provided that protrudes from the side surface of the air flow opening 43, and this dust collecting section 47 has a plurality of turbulent flow walls 49 formed at an appropriate angle of inclination on the lower side, and a plurality of turbulent flow walls 49 in the central part. A suction port 51 is provided.

The dust collecting section 47 is provided with a dust collecting port 53, and the dust collecting port 53 is connected to a dust collecting device outside the machine through a hose 55 or the like (not shown). A cover 57 is attached to the top surface of the dust collecting section 47 with screws or the like so that it can be opened for cleaning.

Because of this configuration, during thermal cutting, spatter or fume, etc. scattered on the upper surface of the workpiece W in the direction of arrow A collides with the air curtain-like compressed air flow ejected from the spout 45 in the direction of arrow B. It becomes a mixed flow.

This mixed flow further hits the turbulent flow wall 49, becomes a turbulent flow, and rises up, and is sucked into the dust collecting device outside the machine via the suction port 51 via the dust collecting section 47, so that there is no adverse effect on the adjacent punching processing section.

It goes without saying that the present invention is not limited to the embodiments described above, and that various changes can be made without departing from the gist of the present invention.

[Effect of idea]

As can be understood from the above description of the embodiments, in short, the present invention includes a punching section that performs punching on the workpiece W, and a thermal cutting section that performs thermal cutting on the workpiece. In the punching/thermal cutting combined processing machine, a partitioning member for partitioning the punching processing part and the thermal cutting processing part is provided between the punching processing part and the thermal cutting processing part. A jet nozzle 45 for blowing out air in an oblique direction on the upper surface of the workpiece W toward the cutting section is provided, and the jet nozzle 45 jets air obliquely onto the upper surface of the workpiece W. A dust collecting section 47 is provided with an inlet 51 for sucking the air that is injected onto the upper surface of the dust collector.

Therefore, according to the present invention, when fumes, spatter, etc. generated in the thermal cutting section tend to scatter toward the punching section, the punching is prevented by the air ejected from the jet port 45 at the bottom of the partition member. This prevents spatter from scattering toward the processing section, and since it is removed by suction through the suction port provided in the dust collection section, spatter and the like are prevented from scattering toward the punching section.
