The utility model provides a temperature-control high-speed large-strain thin film biaxial stretching device. A servo motor drives four guide rails, which are arranged in #-shaped manner, to move, and scissor-fork type mechanisms are used for implementing stretching to a thin film sample. A high pressure pneumatic clamp is used for accomplishing quick clamping to a sample and achieves pressure compensation. Two independent temperature control furnaces are respectively used for device preheating and sample stretching. After the adoption of a hot air circulation system, quick temperature increment of the control furnaces can be achieved, and temperature uniformity of a cavity is ensured. Pulling force sensors are mounted in two stretching directions, and are used for collecting stress strain information during a thin film stretching process. The servo motor drives a ball screw so as to enable the stretching part to switch among different working stations. The temperature-control high-speed large-strain thin film biaxial stretching device provided by the utility model can achieve bidirectional synchronous stretching, bidirectional asynchronous stretching, limited unidirectional stretching and unlimited unidirectional stretching, and is a good device used for simulating industrial thin film stretching processing and building a relation between processing technique parameters and thin film structure properties.
