The mechanical part of the laser tool bit is not in contact with the workpiece, so that the surface of the workpiece cannot be scratched in the working process; the laser cutting speed is high, the cut is smooth and flat, and subsequent processing is generally not needed; the cutting heat affected zone is small, the deformation of the plate is small, and the cutting seam is narrow (0.1 mm-0.3 mm); the notch has no mechanical stress and no shearing burr; the processing precision is high, the repeatability is good, and the surface of the material is not damaged; the numerical control programming can be used for processing any plan, the whole board with large breadth can be cut, a die does not need to be opened, and the method is economical and time-saving.

Meanwhile, in order to ensure the cutting precision of the laser cutting head, the laser cutting head generally needs to be subjected to cold cutting, and the current cooling mode mostly adopts water cooling, but in the water cooling process, along with the flowing of cooling water, the water temperature can be gradually increased, the cooling effect can be reduced, and the uneven cooling effect of a water cooling system can be caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the uneven problem of current laser cutting head water cooling system cooling effect, the technical scheme who adopts is: a self-cooling laser cutting head comprising: the laser cutting head comprises a laser cutting head body, wherein a cooling pipe is coiled outside the laser cutting head body and comprises an inner pipe and an outer pipe, the outer pipe is sleeved outside the inner pipe, one end of the outer pipe is a first water inlet, the other end of the outer pipe is a first water outlet, the first water inlet end of the inner pipe is a second water outlet, and the other end of the inner pipe is a second water inlet.

The further improvement is that the cooling tube is sleeved with a metal cylinder.

The further improvement is that a metal filling piece matched with the shape of the cooling pipe is arranged on the inner wall of the metal cylinder.

The beneficial effects of utility model are that:

the utility model provides a from cold laser cutting head, its cooling tube are the double-deck pipe, and the flow direction of cooling water is opposite in the ectonexine pipeline, and the outer tube cools off with the contact of laser cutting head, and the water of interior intraductal reverse flow cools off the water between outer pipe and the inner tube, consequently makes the temperature in the cooling tube can remain stable for its cooling effect can be stable, unanimous, plays even refrigerated purpose.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings, which illustrate the basic structure of the invention only in a schematic manner, and therefore show only the components relevant to the invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, detachable connections, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the utility model can be understood according to specific situations by those skilled in the art.

As shown in fig. 1 to 3, the utility model provides a self-cooling laser cutting head, include: laser cutting head body 1, the outer cooling tube 2 of laser cutting head body 1 is the heliciform dish outside laser cutting head body 1, cooling tube 2 includes inner tube 21 and outer tube 22, outer tube 22 cover is located outside the inner tube 21, the one end of outer tube 22 is first water inlet 221, the other end of outer tube 22 is first delivery port 222, the inner tube 21 first water inlet 221 end is second delivery port 211, the other end of inner tube 21 is second water inlet 212, that is to say, the interior inner tube is opposite with the interior rivers direction of outer tube.

This self-cooling laser cutting head, its cooling tube are the double-deck pipe, and the flow direction of cooling water is opposite in the ectonexine pipeline, and the outer tube cools off with the contact of laser cutting head, and the water of reverse flow cools off between outer tube and the inner tube in the inner tube, consequently makes the temperature in the cooling tube can remain stable for its cooling effect can be stable, unanimous, plays even refrigerated purpose.

As shown in fig. 4, the cooling pipe 2 is further modified by being externally sleeved with a metal cylinder 3. Because the metal cylinder is contacted with the cooling pipe, the temperature at two ends of the cooling pipe can be further balanced, and the cooling effect is increased and balanced.

As shown in fig. 5, the further improvement is that a filler 31 made of metal is arranged on the inner wall of the metal cylinder 3, the direction of the filler is the same as that of the cooling pipe, and the shape of the gap between the filler and the cooling pipe is matched with that of the gap between the filler and the cooling pipe, so that the contact area between the cooling pipe and the metal cylinder is greatly increased through the filler, the cooling effect of the cooling pipe is better balanced, the laser cutting head is uniformly cooled, and the problem that the cooling effect of the laser cutting head is unbalanced due to the fact that the water temperature gradually rises along with the direction of water flow in the cooling.
