Description
Technical field
The invention belongs to laser process equipment, particularly the high power CO of metallurgy industry
2Laser roughening equipment.
Background technology
Texturing has changed the contact condition of roll and thin plate, can reduce roll-force in thin plate rolling, improve mill speed, reduce scuffing, Bian Lang etc.; Texturing has simultaneously changed the gap between thin plate and thin plate, can prevent the adhesion phenomenon of thin plate in annealing furnace and the slippage of lifting roll bending; Texturing has also changed the pattern of thin plate, can improve the deep drawing quality of next step operation, the property sheared, coating.Along with the urgency of steel market thin plate (galvanized sheet, Coil Coating Products) demand increases, the user is to thin plate diversification, high-quality demand; The competition of the needs of enterprise reduction cost of investment itself, operating cost and market, price, quality, the selection texturing equipment of science and technology seem very important.
By the time that produces, develops, roller surface texturing equipment and technology can roughly be divided into three generations, the first generation: shot-peening texturing equipment and technology, occupy an leading position in 20th century 60, the seventies; The second generation: electric spark texturing equipment and technology progressively obtain leading position in 20th century 80, the nineties; The third generation: laser roughening equipment and technology are just to be born in nearly ten years, have caused showing great attention to of metallurgical and relevant industry with its outstanding advantage.
First CO in the world
2The laser roughening demonstration apparatus is the development in 1984 of Belgian Centre De Recherches Metallurgiques, tried out successfully in automobile factory in 1985, because it obviously is different from electric spark texturing equipment and technology, can arrange in order the texturing surface topography, on a large scale adjust roughness value and density value, good reproducibility, self-enrichment is good, deep drawability is good, so Japan, France, Britain, Germany, some large enterprises of the U.S. begin to introduce, exploitation, use CO
2Laser roughening equipment and technology.But because the restriction of Stimulated Light device quality and optical element performance has brought very big difficulty for Machine Tool design and application.As in order to guarantee the stable of laser facula, German WALDRICH SECGEN company is at " LASER TEX " type CO of early 1990s development
2Laser roughening equipment is characterized in that roll supports do rotation and translation with bearing shell, and laser instrument, outer optic path system and texturing device maintain static, and be constant to guarantee outer light path and beam quality.Ohio, USA continent cold-rolled steel sheet company has produced CO in 1996
2Laser haired machine tool is characterized in that roll is to support only to rotate with the bearing shell, and laser instrument, outer optic path system do parallel moving with the texturing device, and be constant to guarantee outer light path and beam quality.
1, above-mentioned CO
2Laser haired machine tool all is to adopt grinding machine version, and is bulky, and external roll bearing shell automatic station-keeping system complexity, price is very expensive, need of import are 2 times of single head electric spark texturing equipment more than 3,000,000 dollars, have brought certain degree of difficulty to popularization.
2, the roll support lathe bed of grinding machine version and texturing device supporting bed status are from (generally using screw attachment), even adopt costly elastic foundation, because two big lathe bed intrinsic frequencies, excited frequency are different, be difficult to control the stable of a rolling face and a texturing relative position, this is one of key factor that influences the texturing quality.
3, adopt grinding machine version to utilize bearing shell static pressure mode to support axle journal, can guarantee this roll and preceding road grinding process location unifying datum theoretically, but in use roll belongs to and need repair the part of use repeatedly, its dimensional tolerance, form and position tolerance that supports axle journal all can change, can not form the hydrostatic bearing supporting, its rotating speed (is that working (machining) efficiency is subjected to great restriction generally≤80rpm); In a single day and becoming dynamic pressure support, roll rotational speed is that texturing efficient will be subjected to great restriction.
4, the compound motion that adds roll do rotation in man-hour and linear reciprocating motion, light path and texturing device are motionless, not only can increase considerably length, the weight of lathe, and roll and support member thereof are under heavy duty (about 15t), low speed (about 30mm/min), " creeping " very easily appears in hydraulic running, thereby influences the texturing quality.Only rotate as roll, laser instrument does reciprocating linear motion with outer light path (containing the texturing device), can guarantee that outer light path light path is constant, but the lathe volume is still huge.
