【摘要】 依据模具表面摩擦对弯管成形性能的影响规律,利用激光复合织构工艺分别对模具夹块、压块进行激光毛化处理,对防皱板进行激光微造型处理,完成绕弯成形对比试验,采用直接测量法对成型件的外壁减薄率和截面畸变程度进行检测,实验结果表明,复合织构模具比普通模具成型件外壁减薄率降低了0.5%～4.5%,截面畸变程度减轻了0.8%～2%。更多还原

【Abstract】 According to the influence of mold surface friction on the forming of the elbow, respectively on the die clamping block, block of laser texturing using laser composite texture to the crease board process, laser micro texturing processing. The anti-creased board was subjected to laser micro-molding treatment, and the bending test was carried out. The outer wall reduction ratio and distortion degree of the formed parts were measured by direct measuring method. The experimental results show that the reduction ratio of the outer wall of the composite textured mold is 0.5%～4.5%, and the distortion of the cross section is reduced by 0.8%～2%.更多还原
