本发明属于复合板的非晶合金连接和柔性成形技术领域,更具体地,涉及一种金属复合板的一体化制备成形系统及方法.该系统包括前置超声预成形组件和后置主成形组件;前置超声预成形组件用于对预热后的复合待成形复合板坯除去氧化层,并使部分非晶合金被压入待复合成形的金属板表面凹槽中,起到预焊接的作用;再利用后置主成形组件的工具头将加热至过冷液相区的非晶合金压入并充满金属板表面的凹槽中.本发明将现有技术金属板的整体复合离散为金属板之间的点复合,使得金属板之间各个区域随工具头的运动均能被施加相同的应力,以板料的局部变形代替整体变形,减小了板料的回弹量和应力集中现象,实现了变形的均匀分布,提高了板料的成形极限.

The invention belongs to the technical field of amorphous alloy connection and flexible forming of composite plates, and more specifically relates to an integrated preparation and forming system of metal composite plates and a method thereof. The system includes a pre-ultrasonic preforming component and a post-main forming component. The prefabricated ultrasonic preforming module is used to remove the oxide layer from the preheated composite slab to be formed, and the part of the amorphous alloy is pressed into the groove on the surface of the metal plate to be formed, and plays the role of prewelding. An amorphous alloy heated to the undercooled liquid phase region is pressed into a groove that fills the surface of the metal plate using the tool head of the rear-mounted main forming assembly. The whole composite of the prior art metal plate is dispersed into the point composite between the metal plates, so that the same stress can be applied to each area of the metal plate with the movement of the tool head, the local deformation of the plate replaces the whole deformation, reduces the rebound amount of the plate and the phenomenon of stress concentration, realizes the uniform distribution of deformation, and improves the forming limit of the plate.
