Abstract: The invention belongs to the technical field of metal micro-forming, and in particular relates to a method for inflating micro-channels. The present invention is aimed at the problems of low process flexibility, single product type, and non-closed structure of the micro-channel when preparing metal micro-channels by micro-plastic forming of ultra-thin metal strips. The present invention uses a method combining numerical simulation and bond rolling experiment to analyze the effect of the hydrogen pressure and bond strength of the metal composite ultra-thin strip after bond rolling on the pore diameter of the micro-channel, and the corresponding relationship between the micro-channel pore diameter and the titanium hydride content, heating temperature, and bond strength of the metal composite ultra-thin strip is obtained.

Abstract: A transverse vibration rolling system and a preparation method for a double-layer metal composite ultra-thin strip relate to a technical field of rolling, which solve problems including poor rolling and bonding effects, low geometric accuracy, and poor plate shape quality of metal composite ultra-thin strips. The transverse vibration rolling system includes: a first roll, a second roll, a first hydraulic vibrator, a second hydraulic vibrator, a first hydraulic motor, a second hydraulic motor, a check valve, a first hydraulic pump, a first overflow valve, an oil tank, a controller, a second overflow valve, a second hydraulic pump, an electromagnetic reversing valve, a first speed control valve, and a second speed control valve. The transverse vibration of the rolls of the present invention can apply transverse shearing force on the ultra-thin metal strips during the bond rolling.
