The invention belongs to the field of ship manufacturing, and particularly discloses a chamfering process in the ship T profile production process. The chamfering process includes the steps that chamfering scale marks are marked on free sides of a T profile panel, the portions, except for the chamfering scale marks, of the T profile panel are heated through a laser heater, the heated portions arerolled and chamfered, the chamfered portions are cooled and shaped, and a T profile is formed through welding. Firstly, the chamfering scale marks are marked, the chamfered portions of the panel are locally heated in a laser heating manner, the deformation performance of the chamfered portions is guaranteed, and sufficient deformation during following rolling is facilitated; during rolling, the chamfering radian is limited through a guide circular shaft, and the forming precision of chamfering fillets is guaranteed; after rolling is completed, the rolled portions are cooled and shaped in a cold air conveying manner, and the rolled portions are conveniently kept in a chamfering state and are not prone to rebounding; and it is guaranteed that rolling and cooling links are immediately carriedout after heating is completed through the form that heating and side rolling are alternately carried out, heat dissipation is low, the deformation time is short, and the chamfering quality is guaranteed.
本发明属于船舶制造领域,具体公开了一种船舶T型材生产过程中的倒棱工艺,包括在T型材面板各自由边上标记出倒棱刻度线,用激光加热器将倒棱刻度线以外的T型材面板部分加热,对加热部分滚压倒棱,对倒棱部分冷却定型,焊接形成T型材。本发明先标记出倒棱刻度线,采用激光加热的形式对面板倒棱部分局部加热,保证倒棱部分的形变性能,便于后续滚压时形变充分;在滚压时,利用导向圆轴对倒角弧度进行限位,保证倒棱圆角的形成精度;滚压后,利用冷风输送的形式对滚压部分冷却定型,便于保持倒棱状态,不易回弹;并且采用加热和滚边交替进行的形式,保证加热后立即进入滚压、冷却环节,较少热量散失以及形变的时间,保证倒棱质量。
