Abstract
The invention provides a method for testing pulling force applied to snap fasteners. The method comprises the following steps: (1) preparing multiple groups of snap fasteners fixed on a strip-shaped sample for later use; (2) stabilizing the sample by a strength tester, then respectively testing the value of force for separating the occluded snap fasteners in two drawing ways with vertical pulling force and parallel pulling force, and recording force data; (3) simulating the opening and occluding process of undamaged snap fasteners in daily life for several times, observing the breakage of the snap fasteners, repeating the step (2) on undamaged snap fasteners, and then recording the value of force for separating snap fasteners, wherein a note that the snap fasteners are damaged after multiple circulation is added. The method can be used for testing the value of force for separating the snap fasteners which are not used and are used, so that the quality of the snap fasteners can be relatively completely reflected, a basis can be provided for the improvement of the performance of the snap fasteners, and the service life, the quality and other properties of the snap fasteners can be clearly understood and can be used for judging the quality of the snap fasteners of one brand.
Description
Technical field
The present invention relates to a kind of snapper and pull open method for testing strength.
Background technology
Existing snapper pull-out strength test just test does not have the distraction force value of used snapper, but do not require to test snapper use distraction force value after several times.Because snapper is after certain life cycle, may affect usability because wearing and tearing decline distraction force value, use the distraction force value after 500 times so need to increase a snapper, snapper distraction force value before using by test and after using, the quality condition of embodiment snapper that can be more complete.
Summary of the invention
The object of the present invention is to provide a kind of snapper to pull open method for testing strength, the quality condition of the embodiment snapper that this method of testing can be more complete, for the quality estimating of snapper provides means of testing, for the improvement of snapper quality provides foundation.
For solving the problems of the technologies described above, technology of the present invention by the following technical solutions:
A kind of snapper pulls open method for testing strength, it is characterized in that comprising the following steps:
(1) preparing many groups, to be fixed on snapper on strip sample for subsequent use;
(2) the above-mentioned sample strength tester that is fixed with snapper is clamped firm, then the snapper of interlock is vertically pulled open respectively to the powerful and parallel two kinds of drawing modes of brute force of pulling open and test the power value that snapper separates, record the situation of snapper breakage and record the power Value Data recording;
(3) simulation is used snapper in daily life, opens with interlock as a circulation taking snapper, and snapper is carried out observing after several times circulation the damaged situation of snapper:
(a) snapper does not have breakage, repeats above-mentioned steps (2), then the snap-button distraction force value after record use;
(b) snapper breakage, records damage state basedly, and remarks occur damaged after several circulations.
Further, the described concrete steps of vertically pulling open strength test are: upper and lower apart from the each marking in 38mm place, snapper center at sample, and upper and lower mark line spacing 76mm; Then by sample clamping on strength tester, the chuck of strength tester is clipped in mark line place, folder is apart from setting 76mm, the fabric sample of box set is clipped in upper grip, the fabric sample of pin thread set is clipped in lower chuck, set speed of a motor vehicle 305mm/min and stretch, until snapper pin thread separates with box, the power value of record is accurate to 0.4N.
Further, the described parallel concrete operation step that pulls open strength test is: will finish the sample clamping that vertically pulls open strength test on strength tester, the chuck of strength tester is clamped mark line place, folder is apart from setting 76mm, the fabric sample of pin thread set is clipped in upper grip, and the fabric sample of box set is clipped in lower chuck, sets speed of a motor vehicle 305mm/min and stretches, until snapper pin thread separates with box, the power value of record is accurate to 0.4N.
Further, in step (3) snapper to open with the period of interlock be 500 times.
Further, described strength tester is CRE strength tester.CRE strength tester is isodromicing elongation's type strength tester, and its principal feature is that elongation was directly proportional to the time.
The beneficial effect that the present invention compared with prior art has is: the distraction force value before the present invention uses by test snapper respectively and after using, and the quality condition of embodiment snapper that can be more complete, can provide foundation for the improvement of the performance of snapper; In addition, distraction force value from the snapper that records uses, can clearly recognize the situation such as serviceable life, quality of snapper, thereby can be for judging the quality of snapper quality of a brand.
Embodiment
For allowing the more clear and intuitive understanding the present invention of those skilled in the art, below the present invention is further illustrated.
A kind of snapper pulls open method for testing strength, comprises the following steps:
(1) preparing many groups, to be fixed on snapper on strip sample for subsequent use;
(2) the above-mentioned sample CRE strength tester that is fixed with snapper is clamped firm, then the snapper of interlock is vertically pulled open respectively to the powerful and parallel two kinds of drawing modes of brute force of pulling open and test the power value that snapper separates, record the situation of snapper breakage and record the power Value Data recording;
(3) simulation is used snapper in daily life, opens with interlock as a circulation taking snapper, and snapper is carried out observing after 500 circulations the damaged situation of snapper:
(a) snapper does not have breakage, repeats above-mentioned steps (2), then the snap-button distraction force value after record use;
(b) snapper breakage, records damage state basedly, and remarks occur damaged after 500 circulations.
Wherein, the concrete steps of vertically pulling open strength test are: upper and lower apart from the each marking in 38mm place, snapper center at sample, and upper and lower mark line spacing 76mm; Then by sample clamping on CRE strength tester, the chuck of CRE strength tester is clipped in mark line place, folder is apart from setting 76mm, the fabric sample of box set is clipped in upper grip, the fabric sample of pin thread set is clipped in lower chuck, set speed of a motor vehicle 305mm/min and stretch, until snapper pin thread separates with box, the power value of record is accurate to 0.4N.
The parallel concrete operation step that pulls open strength test is: will finish the sample clamping that vertically pulls open strength test on CRE strength tester, the chuck of CRE strength tester is clamped mark line place, folder is apart from setting 76mm, the fabric sample of pin thread set is clipped in upper grip, the fabric sample of box set is clipped in lower chuck, set speed of a motor vehicle 305mm/min and stretch, until snapper pin thread separates with box, the power value of record is accurate to 0.4N.
The distraction force value of snapper after the distraction force value of snapper and No. 500 switches before using by record, the quality condition of embodiment snapper that can be more complete, can provide foundation for the improvement of the performance of snapper; In addition, distraction force value from the snapper that records uses, can clearly recognize the situation such as serviceable life, quality of snapper, thereby can be for judging the quality of snapper quality of a brand.
