滚压复合机在多个工业领域发挥着关键作用，其工作原理基于机械力、压力及材料特性的协同作用，以实现不同材料的复合加工。不同类型的滚压复合机因应用场景不同，工作原理存在一定差异，以下以常见的金属板材滚压复合机和管材滚压复合机为例进行介绍。

The rolling composite machine plays a key role in multiple industrial fields, and its working principle is based on the synergistic effect of mechanical force, pressure, and material characteristics to achieve composite processing of different materials. Different types of rolling composite machines have certain differences in their working principles due to different application scenarios. The following will introduce common metal sheet rolling composite machines and pipe rolling composite machines as examples.

Working principle of metal sheet rolling composite machine

　　送料系统运作：在金属板材滚压复合的起始阶段，送料系统承担着重要职责。该系统通常由电机驱动的辊轮组构成，其运转速度可依据加工工艺要求进行精准调控。金属板材被放置于送料台上，在辊轮的摩擦力作用下，板材被平稳且匀速地送入滚压复合区域。送料的精准度和稳定性对复合质量影响重大，若送料速度不均匀，会导致复合后的板材出现厚度不均、贴合不紧密等问题。例如，在汽车制造中用于生产车身覆盖件的滚压复合机，送料系统需将不同材质的金属薄板精确地送入，确保后续复合工序顺利进行。

The operation of the feeding system: In the initial stage of metal sheet rolling composite, the feeding system plays an important role. This system is usually composed of a roller set driven by a motor, and its operating speed can be precisely controlled according to the processing requirements. The metal sheet is placed on the feeding platform, and under the frictional force of the rollers, the sheet is smoothly and uniformly fed into the rolling composite area. The precision and stability of feeding have a significant impact on the quality of composite materials. If the feeding speed is uneven, it can lead to uneven thickness and loose bonding of the composite board. For example, in the production of car body coverings using a rolling laminating machine, the feeding system needs to accurately feed metal sheets of different materials to ensure the smooth progress of subsequent laminating processes.

　　滚压成型过程：当金属板材进入滚压复合区域后，会遭遇一系列经过特殊设计的滚压模具。这些模具一般成对设置，且表面具有特定的形状和纹理。上下模具在电机通过传动装置提供的动力驱动下，以相反方向高速旋转。在旋转过程中，模具对板材施加强大的压力和摩擦力。压力促使板材发生塑性变形，而摩擦力则带动板材在模具间移动。通过多组不同形状模具的依次滚压，板材逐渐被加工成预定的形状。以生产波纹状金属复合板为例，滚压模具表面设计有与波纹形状对应的凹槽和凸起，在滚压过程中，板材在模具作用下形成规则的波纹结构，同时不同金属层在压力作用下紧密贴合，实现复合。

Rolling forming process: When the metal sheet enters the rolling composite area, it will encounter a series of specially designed rolling molds. These molds are usually set up in pairs and have specific shapes and textures on their surfaces. The upper and lower molds rotate at high speed in opposite directions under the power provided by the motor through the transmission device. During the rotation process, the mold exerts strong pressure and friction on the sheet metal. Pressure causes plastic deformation of the sheet, while friction drives the sheet to move between the molds. By sequentially rolling multiple sets of molds with different shapes, the sheet is gradually processed into the predetermined shape. Taking the production of corrugated metal composite plates as an example, the surface of the rolling mold is designed with grooves and protrusions corresponding to the corrugated shape. During the rolling process, the plate forms a regular corrugated structure under the action of the mold, and different metal layers are tightly adhered under pressure to achieve composite.

　　复合原理机制：金属板材滚压复合机实现复合的核心在于压力和材料特性的相互作用。在滚压过程中，强大的压力使得不同金属板材的原子间距离减小，当达到一定程度时，原子间产生相互吸引力，从而形成冶金结合，实现真正的复合。为增强复合效果，有时会在复合前对板材表面进行预处理，如清洁、打磨，以去除表面的氧化层和杂质，使板材表面更洁净，利于原子间结合。此外，还可通过控制滚压温度来辅助复合，在一些特殊金属材料的复合中，适当升高温度可提高原子的活性，促进原子扩散，进一步加强复合强度。

Composite principle mechanism: The core of metal sheet rolling composite machine to achieve composite lies in the interaction between pressure and material properties. During the rolling process, strong pressure reduces the distance between atoms of different metal sheets. When it reaches a certain level, mutual attraction is generated between atoms, forming metallurgical bonding and achieving true composite. To enhance the composite effect, sometimes the surface of the board is pre treated before composite, such as cleaning and polishing, to remove the oxide layer and impurities on the surface, making the board surface cleaner and conducive to interatomic bonding. In addition, the composite can be assisted by controlling the rolling temperature. In the composite of some special metal materials, increasing the temperature appropriately can improve the activity of atoms, promote atomic diffusion, and further enhance the composite strength.
