Description
Technical field
The present invention relates to clamp art, particularly relate to a kind of fabric strength machine stretching device ultra-wide fixture.
Background technology
Non-weaving cloth is when stretching, and significant transversal shrinkage phenomenon can occur its sample, is generally referred to as " constriction ".The existence of " constriction " phenomenon makes the tensile mechanical properties of non-weaving cloth be a greater impact, and pulling strengrth generally can be caused less than normal than actual value.He Chaolin, get the ratio that good fortune (paper: the tensile property of non-woven geotextile) have studied non-weaving cloth different in width Tensile strength and 1000mm width Tensile strength Wei, found that, when sample is more than 500mm width, stretch test result reduces gradually by the impact of width, and ratio trends towards 1.Liu Ruichao, Zhou Rong (paper: test condition is on the impact of needle fabric tensile property) have studied the impact of test condition on needle fabric tensile property, point out specimen width having the greatest impact to tension failure brute force, reach the degree of appreciable impact; Shang Xinping, Chu Caiyuan (impact of Specimen Width of Nonwoven Geotextiles on Tensile Properties) research is pointed out, the relation of different pulling strengrth corresponding to length growth rate and specimen width can be divided into two stages: when length growth rate is less, pulling strengrth does not have marked change with the increase of specimen width; When length growth rate is larger, pulling strengrth increases with the increase of specimen width.
The formulation of domestic and international associated test standards have also contemplated that the impact of specimen width, as GB/T176371998 regulation conventional examples is of a size of 50mm × 200mm (wide × long), constriction " sample of phenomenon obviously (>=10%) is 200mm × 200mm; GB/T15788 and Unite States Standard (USS) ASTMD4595 adopts 200mm × 100mm; Canadian and most of European countries standard adopts 500mm × 100mm.But sample is wider, test difficulty is larger, and expense is also higher, and higher to the requirement of chuck.The fixture that existing fabric strength machine is used, the inner face of its intermediate plate has two kinds of forms, a kind of is that (two metal intermediate plate clamping faces are furnished with many grooves for the concave-convex clutch structure of metal covering, the depression of projection another clamping face corresponding of a clamping face), two intermediate plate clampings are made by knob, the shortcoming of this structure is exactly that easily damage clamps fabric, and the stress causing fabric to clamp ora terminalis is concentrated, and sample is ruptured in clamping place.Another is the glued construction of metal intermediate plate and rubber, namely uses bonding agent to be stained with one deck elastomeric material at the inner face of metal intermediate plate, forms the composite structure of metal intermediate plate and elastomeric material, elastomeric material direct contact fabric during clamping fabric.This structure is not easy damage clamping fabric, but easily not clamping when sample is wider, causes the slippage clamping fabric.And under repeatedly clamping, rubber layer is easy to and metal covering departs from, and causes the inefficacy of fixture.
