Over the years, the machinery industry growth rate is higher than the industrial average, efficiency growth is also higher than the same period last year, production and sales growth, concrete burning laser pointer paver as a necessary equipment in the construction machinery, has also been high sales. Concrete laser leveling machine, the production efficiency increased by 61%, the construction cost savings of 49%, the construction period by 40% floor strength and compactness increased by 25%, flatness error to Germany related product standards.
Intelligent handle mode of operation, flexible control, single operation can be operated. Mobile steering flexible and convenient, through the handle to control the walking system, making the machine free to move, and the flat head does not affect each other, the use of manual control of the wheel forward, backward, steering and travel speed, moving very convenient. high power laser pointer launchers are arranged independently, large area of the overall pavement to ensure that the ground elevation uniform, elevation from the template control, will not produce errors, large area block construction, can reduce the construction joints, so that the ground maintenance costs greatly reduced.
Integral leveling head: by the scraper, vibrator, vibration plate, cage and other components, will be stirring, leveling, vibration level, vibration and other multi-channel process together, completed by the machine one-time. Improve efficiency, save labor. In the base of ups and downs and the road surface tilt, to maintain the construction of the horizontal plane. 4000 times per minute high-frequency vibration of the flat head vibration plate uniform high-frequency vibration, making the concrete ground dense, decentralized deformation stress. Can effectively solve the ground empty drum, from the shell, cracking, inequality
Laser measurement and control system automatically control the elevation, the top floor of the floor design by the green astronomy laser machine computer automatic control, to ensure that the ground level, directly on the concrete layer to achieve accurate leveling, ground flatness from the construction template vibration, the middle without support, Artificial materials investment, shorten the construction process, speed up the construction progress. Per hour construction area of 300 square meters above the daily work to complete the 3000 ㎡ to 5000 ㎡ or more, greatly enhance the operating efficiency!
For a given laser power density and material, the cutting speed is in accordance with an empirical formula. As long as the threshold is above the threshold, the cutting speed of the material is proportional to the laser power density, that is, increasing the power density can increase the cutting speed. The power density referred to here is related not only to the laser output power but also to the beam quality mode. In addition, the characteristics of the beam focusing system, that is, after focusing the spot size also has a great impact on 1w laser pointer cutting.
The cutting speed is inversely proportional to the density and thickness of the material being cut. (Such as from high-order mode to low-order mode up to TEM00); reduce the focus spot size (in the range of 500 to 2 000 W) Such as plastic, plexiglass, etc.); cutting low-density materials (such as white pine, etc.); cutting thin materials.
In particular, for metal materials, the laser cutting speed can have a relative adjustment range while maintaining a satisfactory cutting quality when the other process variables remain constant. This adjustment range appears to be slightly smaller than that of the thicker width. Sometimes, the slow cutting speed will lead to the excretion of hot melt material surface, so that the surface is very rough.
Since the 3000mw green laser power density has a great influence on the cutting speed, the choice of lens focal length is an important problem. After focusing the laser beam, the spot size is proportional to the focal length of the lens. After the beam is focused by the short focal length lens, the spot size is very small and the power density at the focal point is very high, which is advantageous for cutting the material; but its disadvantage is that the depth of focus is very short, Small, generally more suitable for high-speed cutting thin materials. As the telephoto lens has a wide focal length, as long as there is sufficient power density, more suitable for cutting thick workpiece.
