Embodiment Construction

[0023] In the following, the present invention will be further described in detail with reference to the accompanying drawings, embodiments and effect examples, instead of limiting the present invention.

[0024] Such as Figure 1-3 As shown, a water mist cooling laser cutting system includes a cutting head 1, a water pump 2, and a compressed air pump 3. The cutting head 1 includes a nozzle 4 and a ceramic body 5. The nozzle 4 is insulated and connected to the frame through the ceramic body 5. The ceramic body 5 is provided with a water mist channel 6, a delivery pipe 7 is provided between the water pump 2, the air pump, and the water mist channel 6, and the nozzle 4 is provided with a light channel 8 through which laser light passes. 8 at the same time for the cutting gas to pass through. The cutting head 1 is provided with a number of spray holes 9 arranged around the light channel 8. When the ceramic body 5 and the nozzle 4 are connected, the water mist channel 6 and the plura...

Abstract

The invention discloses a water spray cooling laser cutting system. The water spray cooling laser cutting system comprises a cutting head, a water pump and a compression air pump; the cutting head comprises a nozzle and a ceramic body; the nozzle is in insulation connection with a machine frame through the ceramic body; the ceramic body is provided with a water spray channel; conveying pipelines are arranged between the water pump, the air pump and the water spray channel; the axis of the nozzle is provided with a laser channel for allowing laser to pass; the cutting head is provided with a plurality of spraying holes surrounding the laser channel; and when the ceramic body is connected with the nozzle, the water spray channel communicates with the multiple spraying holes. In addition, theinvention further discloses a cutting method of the water spray cooling laser cutting system. According to the water spray cooling laser cutting system and the cutting method thereof, water spray canquickly evaporates to take away heat when being sprayed on the surface of a cutting plate, the spraying path is moved along with moving of the cutting head, energy saving is achieved, in addition, targeted cooling is efficiently conducted, cutting stability is ensured, and the effect that the overall cutting edge is regular and smooth is realized.

Description

Technical field [0001] The invention relates to the field of laser cutting, in particular to a water mist cooling laser cutting system and a cutting method thereof. Background technique [0002] High-power laser cutting has become the mainstay equipment of today's sheet metal processing, and its advantages such as high processing efficiency and high precision are widely favored by the market. However, when cutting carbon steel with high power, oxygen reacts with the plate to release a large amount of heat, which makes the plate hot. When processing more complex patterns, as the processed parts increase, the plate temperature rises sharply, which changes the carbon steel in laser processing. The required melting temperature and the absorptivity of the plate to the laser cause the cutting cannot be sustained and stable. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to spray the plate during the laser cutting ...
