Problems solved by technology

However, due to the error of the transmission mechanism in the above structure, it will be difficult to achieve synchronous stretching.
However, for the above structure, to achieve synchronous stretching of the material from the tangential and normal directions, the precision of the transmission mechanism is high, which makes the structure of the whole device more complicated and the volume is

Abstract

The invention discloses a dual-shaft synchronous stretching device, which comprises a fixed frame, a stretching stand and a stretching assembly, wherein a longitudinal clamp I is fixedly arranged on the stretching stand; and a transverse clamp I, a transverse clamp II and a longitudinal clamp II are respectively driven by the stretching stand to realize stretching motion. According to the dual-shaft synchronous stretching device disclosed by the invention, the fixed frame and the stretching stand are combined to form a steering wheel structure; the stretching stand is driven by a stretching and driving device to realize simultaneous stretching motion of dual-shaft four clamps, i.e. the dual-shaft synchronous stretching effect is achieved by uniaxial stretching so as to obtain more accurate stretching data and result; and in addition, the dual-shaft synchronous stretching device has a simple structure, can be used for realizing dual-shaft stretching on a uniaxial stretching tester and solving the problems of complex structure and high cost for bidirectional synchronous stretching in the prior art. The dual-shaft synchronous stretching device has extremely-low cost and is suitable for dual-shaft stretching tests of rubber and other materials.

Description

technical field [0001] The present invention relates to a material stretching device, in particular to a biaxial stretching device for rubber materials, suitable for testing applications and production applications. Background technique [0002] Tensile is the process of elongating the material or sample plane under test or production conditions to obtain the required test parameters and products. Generally, it can be divided into uniaxial, biaxial and multiaxial stretching according to the needs. [0003] Biaxial stretching refers to a construction process that stretches in both the normal and tangential directions. [0004] In the prior art, the biaxial stretching device adopts a combination of clamps along the tangential and normal directions, and uses a relatively independent driving device, or uses the same driving device to drive with different transmission mechanisms, which can realize biaxial stretching . The transmission mechanism mostly adopts a rack and pinion ...
