Pulling device for testing ductility of fabrics

Abstract

The invention discloses a pulling device for testing ductility of fabrics. The pulling device comprises a worktable; a semicircular arc-shaped groove is formed in one side of the bottom end of the worktable; a rotating mechanism is arranged in the semicircular arc-shaped groove; the rotating mechanism comprises a driving shaft; a driven shaft is arranged on one side of the driving shaft; a bottomplate is arranged at the upper end of the worktable; clamping plates are arranged at the side ends of the bottom plate; snap-gauges and side plates are arranged at the side ends of the clamping plates; air cylinders are fixed at the side ends of the worktable; and a support rod is fixed between the tops of piston rods on the air cylinder. Through the snap-gauges and the side plates at the side ends of the clamping plates, the fabrics can be fixed; after fastening bolts are matched with threaded holes, limiting pins are inserted into limiting holes, so that double-fixing for the fabrics is realized, thereby ensuring the firm fixing and ensuring the fabrics not to be lacerated during the pulling so as to ensure the test correctness; and meanwhile, after the test for one ends of the fabrics is finished, the users do not to fix the other ends through relieving the fixing after the test on one side, so that the operation steps are saved and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of fabric testing, in particular to a pulling device for testing the ductility of fabrics. Background technique [0002] In material science, ductility is the ability of a material that is particularly noticed when the material is deformed by tensile stress. The ductility is mainly manifested when the material is stretched into a line; ductility is another similar concept, but it is expressed as The ability of a material to deform under compressive stress without rupturing. When it is necessary to test the stretchability of the fabric, one end of the fabric needs to be fixed and the other end should be pulled. [0003] In the prior art, when one end of the fabric is not fixed firmly enough, it is easy to cause shedding while being pulled; when one end of the fabric is penetrated by a tool and fixed too firmly, it is easy to cause tearing of the end of the fabric while pulling, will lead to inaccurate measurement; ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the deficiencies mentioned in the above-mentioned background technology, the object of the present invention is to provide a pulling device for testing the ductility of the fabric. The present invention fixes the fabric through the clamping plate and the side plate provided at the side end of the clamping plate, and tightens the bolts. After matching with the threaded hole, insert the limit pin into the limit hole to realize the double fixation of the fabric, which can not only ensure the firm fixation, but also ensure that the fabric will not be torn when pulled, ensuring the accuracy of the measurement sex;
