Abstract

The invention discloses a clamp for an extension test of a glass fiber tape for an optical cable and a testing method. The clamp comprises a bottom plate, wherein a cylindrical fixing head with a hole is fixedly arranged on the upper side of the bottom plate, a ring and a fixing plate are fixedly arranged on the lower side of the bottom plate, and a clamping fixing device and an I-type clamping device which are matched for use are fixedly mounted on the plate edge at the middle section. According to the clamp for the extension test of the glass fiber tape for the optical cable and the testing method, the technical problem that the glass fiber tape for the optical cable cannot be used for the extension test is solved; two ends of the glass fiber tape are clamped through the clamping fixing device and the I-type clamping device, so that the glass fiber tape cannot slide, rubber pieces are arranged in clamping structures, have the function of friction increase and can protect the glass fiber tape, the ring is wound with the glass fiber tape, the surface of the ring is polished, the glass fiber tape cannot be easily damaged, a test result cannot be affected, and the strength of the glass fiber tape can be tested.

Description

technical field

[0001] The invention relates to a device and a method for testing the tensile performance of ribbons, in particular to a fixture and a testing method for tensile testing applicable to glass fiber ribbons for optical cables. Background technique

[0002] The tensile test of materials is one of the most common methods in the testing of mechanical properties of materials. The stages of elastic deformation, plastic deformation and fracture in the test truly reflect the whole process of the material resisting external force. Although the success of a tensile test depends on many factors, the grips are one of the most basic and important pieces of equipment.

[0003] At present, two clamps are generally required to fix the two ends of the test material respectively during the tensile test. Among them, the upper fixture is used to fix the data sensor, and the lower fixture is used to fix the machine base. The sample is placed vertically between the two fixtures, a...

Embodiment Construction

[0036] The present invention is a kind of jig for tensile test of glass fiber ribbon for optical cable, refer to Figure 1 to Figure 7 , which specifically includes a base plate 1, the upper side of the base plate 1 is fixedly equipped with a cylindrical hole fixing head 2, and the lower side is fixedly equipped with a ring 3 and a fixed disc 4, and it is also fixedly installed on the edge of the middle plate. Clamping fixture 5 and I-type clamping device 6.

[0037] Among them, the bottom plate 1 is made of No. 45 steel material, and has been quenched and tempered and surface quenched. There are several fixing holes on it. The position and size of the fixing holes must be accurate. Roughness needs to reach 1.6.

[0038] The fixed head 2 with a cylindrical hole is made of No. 45 steel material, and after quenching and tempering treatment, all acute angles are inverted into obtuse angles, deburred, and the surface roughness must reach 1.6. For the cylindrical head fixed with ...
