层状金属复合板以优良的材料和结构性能在舰船、汽车和飞行器等装备中显示了广阔的应用前景。为研究工艺因数对层状金属复合板激光弯曲成形的影响,以不锈钢-碳钢层合板为研究对象,对这种层状金属复合板的激光弯曲角度和规律进行了系统的试验研究。结果表明,不锈钢-碳钢层合板和不锈钢板激光弯曲存在共性,弯曲角度随着激光功率增加而增大,随着扫描速度增加而减小,随着扫描次数增加而增大,随着板厚增大而减小。同时二者也存在差异;随着不锈钢-碳钢层合板宽度的增加,弯曲角度先减小后增大;在相同工艺条件下,不锈钢-碳钢层合板弯曲角度大于不锈钢板的弯曲角度,并在一次固定安装下获得85.6°这一接近直角的极限弯曲角度。
Layered metal composite panels with excellent material and structural properties in ships, vehicles and aircraft and other equipment has shown a broad application prospects. In order to study the effect of process factor on the laser bending of layered metal clad laminates, the laser bending angle and regularity of this cladded metal clad laminates were systematically studied with stainless steel-carbon steel laminates as the research object. The results show that the laser bending of stainless steel-carbon steel laminates and stainless steel plates are common, the bending angle increases with the increase of laser power, decreases with the increase of scanning speed, increases with the increase of scanning times, Increase and decrease. At the same time, there are also differences between them. With the increase of the width of the stainless steel-carbon steel laminate, the bending angle first decreases and then increases. Under the same conditions, the bending angle of the stainless steel-carbon steel laminate is larger than that of the stainless steel In a fixed installation to obtain 85.6 ° near the right angle limit bending angle.
