矫圆筒定位点焊工艺.docVIP

矫圆筒定位点焊工艺 用目视观察辊筒的中间位置，上辊的外形线与板边是否平行调整对中。 with the visual observation of the intermediate position of the roller, the roller contour lines and edge parallel to the adjustment. 圆柱的卷弯，将板料位置对中后，一般采用多次进行滚弯，调节上辊，逐步压下上辊并来回滚动，使板料的曲率半径逐渐减小直至达到规定的要求，在卷弯过程中，应不断地用样板检验弯板两端的曲率半径。卷弯半圆（瓦片）时也应卸载后测验量其曲率。 cylindrical roll bending, the plate location for, generally using multiple times to roll bending, roll adjustment, pressure roller and rolling back and forth, step by step to make sheet metal curvature radius decreases until reached the requirements of regulation, in the process of roll bending, should constantly use template radius of curvature at the ends of the test plate. Roll bending round (tiles) should also be its curvature after unloading test. 矫圆工艺、圆筒卷弯焊接后会发生焊后变形，所以必须进行矫圆。矫圆分加载、滚圆和卸载三个步骤。先根据经验或计算，将上辊筒调节到重要的最大矫正曲率的位置，使板料受弯。板料在卷板机辊筒的矫正曲率下来回滚卷1-2圈，着重在滚卷焊缝区附近用卡样板检查，使整圈曲率均匀一致，然后在滚卷的同时，逐渐退回辊筒，使工件在逐渐减少矫正载荷下多次滚卷至要求，也可用手矫圆。圆锥面的卷弯过程与圆柱面制作工艺相似。 round correction technology, drum roll bending will occur after welding deformation after welding, so must be round correction. Circle points loaded and rolling and uninstall three steps. According to experience or calculated first, and will roll on the adjustment to the important position of the maximum curvature correction, make the sheet metal bending. Blank in curvature to rectify the bending roll roller down to rollback (1-2 laps, emphatically in the roll weld zone near the card sample to check, make the whole circle of curvature uniform, and then roll up at the same time, gradually returned to the roller, the workpiece under the load gradually reduce correction roll up to a request for many times, also can use hand round correction. On the surface of the conical roll bending process similar to cylinder production process. 卷板质量：卷板质量问题包括外形缺陷、表面压伤和卷裂三个方面。 roll plate quality: the quality of rolled plate problems including crushed appearance defects, surface and volume split in three aspects. 外形缺陷，在操作中要注意以下现象：a 卷弯圆柱形筒体时外形出现
