Description
技术领域technical field
本发明属于夹持薄膜材料拉伸试验技术领域，特别是一种薄膜材料拉伸试验夹头装置。The invention belongs to the technical field of clamping film material tensile test, in particular to a clamp device for film material tensile test.
背景技术Background technique
随着现代科技的不断发展，各种薄膜材料被广泛应用。薄膜材料的力学性能研究是当前的一大热点。拉伸试验是研究材料力学性质最基本的试验，对薄膜材料进行拉伸研究，考虑最基本的问题就是薄膜试件的夹持。With the continuous development of modern technology, various thin film materials are widely used. The research on the mechanical properties of thin film materials is a hot spot at present. Tensile test is the most basic test to study the mechanical properties of materials. The most basic problem to consider when conducting tensile research on thin film materials is the clamping of thin film specimens.
通常拉伸试验机所配备的是楔形拉伸夹具，其基本原理是通过调节夹具上的搬把，促使夹具体可以上升或下降，调节楔块之间间距，适应不同板材试件厚度，但此类夹具在设计时都存在最小夹持厚度，小于该厚度的材料将无法被夹持进行试验，以往解决方案是在试验薄膜两端粘接增厚块来增加夹持端厚度，以达到最小夹持厚度的要求。但是，上述解决方案存在一定缺陷，一方面，采用粘接增厚块的方式制备试件效率不高，进行多组拉伸试验时，需要粘接多组；另一方面，粘接胶可能对薄膜材料与增厚块粘接根部的力学性能产生影响，导致最终获取的材料力学性能有偏差。因此，需要设计一种对材料力学性能不产生影响，同时夹持厚度能由零变化到一定厚度的特定夹头。Usually, the tensile testing machine is equipped with a wedge-shaped tensile fixture. The basic principle is to adjust the handle on the fixture to make the clamp body rise or fall, adjust the distance between the wedges, and adapt to the thickness of different plate specimens. There is a minimum clamping thickness in the design of such fixtures. Materials smaller than this thickness will not be able to be clamped for testing. The previous solution is to bond thickened blocks at both ends of the test film to increase the thickness of the clamping end to achieve the minimum clamping thickness. Hold thickness requirements. However, the above solutions have certain defects. On the one hand, the preparation of specimens by bonding thickened blocks is not efficient, and multiple groups need to be bonded when performing multi-group tensile tests; The mechanical properties of the bonded root of the film material and the thickened block are affected, resulting in deviations in the mechanical properties of the final material. Therefore, it is necessary to design a specific chuck that does not affect the mechanical properties of the material, and at the same time the clamping thickness can be changed from zero to a certain thickness.
