Description
Technical Field
The invention relates to laser cutting, in particular to double-blowing ignition-proof CO2Laser cutting head.
Background
CO2The laser cutting machine has a working principle that the stimulated emission process is complex, and molecules have three different motions, namely the motion of electrons in the molecules, and the motion determines the electronic energy state of the molecules; the atoms in the molecule vibrate, i.e. the atoms in the molecule do periodic vibration around the equilibrium position without stop-and are determined by the vibration energy state of the molecule; thirdly, molecule rotation, namely, the molecule rotates continuously in space as a whole, the motion of the molecule determines the rotation energy state of the molecule, and the CO2 laser cutting machine is mainly applied to acrylic, acrylic and acrylic,Cutting non-metal materials such as wood boards, paper products, leather cloth and the like.
In the laser cutting process, heat is generated to lead the material to deform or catch fire, particularly when flammable materials such as acrylic materials are cut, the phenomenon of catching fire often happens, at present, a laser cutting machine manufacturer can particularly remind a user that people need to guard to prevent fire when the laser cutting machine manufacturer works, and due to the fact that the cutting speed of the material with large breadth or thickness is very low, each plate can be processed for two to three hours. The phenomenon that operators leave is common, so countless equipment firing events occur in the industry every year, equipment needs to be repaired or scrapped to different degrees when the equipment is lighter, fire disasters occur when the equipment is heavier, 90% of acrylic cutting users have light or heavy firing phenomena, and two cases of serious fire disasters occur when the laser cutting machine cuts acrylic every year. If serious fire caused by cutting acrylic by laser occurs in 2018 in Zhengzhou Zhongli advertisement market with centralized advertisement processing, a market management department strictly requires that entrepreneurs cannot use a laser cutting machine and seal laser cutting equipment of all the merchants. In 12 months in 2019, two devices sold in our company in the year play fire events, the two devices are completely scrapped, one device is a Chengdu user and a Taiyuan Shanxi user, and the laser cutting device has the advantages of good processing quality and no need of polishing after fixed processing in the application of cutting acrylic. The user is always troubled by the problem of firing, and when the equipment works, no matter how long each edition of processing needs, operators are required to watch, and the labor is seriously wasted. The fire can be caused by slight negligence, the fire is discovered and treated in time, the cost is reported for one version of materials, the damage of a machine is discovered later, an operator leaves for a long time, particularly night shift or overtime, and the risk of fire is great. Because the processed semi-finished products and raw materials are stacked near the processing user equipment, a serious fire disaster is easy to happen, and the defects of using the laser cutting machine are overcome. The blowing is carried out by using a single blowing hole and laser in the same way, the blowing is directly cooled to the seam through an air nozzle, and the laser and the blowing in the same way are output through a nozzle taper hole in the method, so that the lens protection and the cutting surface cooling are realizedWhen the blowing pressure is increased, although the risk of fire can be prevented, the blowing is slightly increased, the cutting effect becomes poor, and the cut upper surface becomes whitish or widened. Is a problem caused by that the area of the slit which is rapidly melted by the laser is blown to be deformed or rapidly cooled by the high pressure gas. When a user actually processes, the method is not adopted, and the first factor is that the user can achieve a better or qualified processed product in actual use; and secondly, the device sends out alarm sound to remind a user through smoke induction or other induction, and the induction device has high false alarm rate due to smoke generated by laser cutting. Even if the feeling device does not give a mistake, the probability that the problem can be effectively solved by the alarm mode after the fire happens is not high, most of users in the fire disaster leave for a long time, go to a dormitory for rest or go to have a meal, most of the users in the fire disaster still go to night shifts or overtime, the alarm efficiency is low, and therefore the double-blowing anti-fire CO alarm is invented2A laser cutting head solves the above problems.
