Abstract
The utility model discloses a wire extension fatigue testing device. The device comprises a base, two support racks stretched from the base, an extension device fixed below the support racks and a fixing device fixed above the support racks for fixing a testing wire, wherein the extension device is provided with at least a group of weights which is connected with the other end of the testing wire. The fatigue testing device can be used for testing the extension fatigue service life of a sample through the constant weight of the weights, thus not only guaranteeing the same stress of extension each time on the sample, but also more really stimulating the stress service life of the sample in actual use process; and the device has a simple structure, is low in cost and is convenient in actual operation.
Description
Technical field
The utility model relates to the testing fatigue field, relates in particular to the flexible fatigue test device of a kind of wire rod for headphone line.
Background technology
The flexible fatigue test device of existing headphone line is mainly that the headphone line product adopts Pneumatic pressure power repeatedly to be stretched to continuously certain-length, to inspect its impaired position and flexible number of times, but because this kind test method is fixed the tensile elongation of headphone line product, increase along with flexible number of times, when product is stretched to initial setting length, proving installation reduces gradually to the stress of product, thereby causes test result accurate not.
The utility model content
The purpose of this utility model is the defective that exists for above-mentioned prior art, proposes the flexible fatigue test device of a kind of wire rod.
The technical solution adopted in the utility model is, design the flexible fatigue test device of a kind of wire rod, two bracing frames that comprise pedestal, stretch out from pedestal, be fixed on the retractor device of bracing frame below and be fixed on the stationary installation that is used for the fixing test wire rod of bracing frame top, described stationary installation is provided with the wire rod folder of at least one group of clamping test wire rod one end, be provided with at least one group of counterweight on described retractor device, this counterweight is connected with the test wire rod other end.
Described retractor device comprises the back up pad that is fixed on bracing frame, the cylinder of being located at the back up pad below, and this cylinder stretches out a piston rod, and the top of piston rod is provided with the pallet of a placement counterweight.
Described back up pad is fastening by screw and bracing frame, and can adjust up and down the position.
Described stationary installation being by being fixed on the link on bracing frame and being fixed on this link, and the wire rod that can move left and right folder consists of, and described stationary installation is provided with the wire rod folder of at least one group of clamping test wire rod one end.
Described link two ends are provided with fixed block, and this fixed block can slide up and down along bracing frame, and pass through screw fastening.
Described wire rod folder is fastening by screw and link.
Compared with prior art, the constant gravity of the utility model by counterweight is to sample test fatigue lifetime of stretching, not only guaranteed each flexible consistent to the stress of sample, and emulation more realistically sample stress life in actual use; This device construction is simple, with low cost simultaneously, and practical operation is easy.

Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, two bracing frames 2 that the flexible fatigue test device that the utility model proposes comprises pedestal 1, stretch out from pedestal, be fixed on the retractor device 3 of bracing frame below and be fixed on the stationary installation 4 that is used for the fixing test wire rod of bracing frame top, be provided with one group of counterweight 35 on retractor device, this counterweight is connected with test wire rod 5 other ends.
As shown in Figures 1 to 4, retractor device 3 comprises back up pad 31, be located at the cylinder 33 of this back up pad lower floor, and this cylinder stretches out a piston rod 32, and the top of piston rod is provided with a pallet 34 of placing counterweight.Wherein back up pad 31 is passed two bracing frames 2, and its both sides are fastening by screw and bracing frame, and can adjust up and down the position; Simultaneously be placed with one group of counterweight 35 on pallet 34, hook 351 set on this counterweight catches on an end of testing wire rod 5, and the other end of this test wire rod is fixedly connected with stationary installation 4.
As Fig. 1, shown in Figure 5, stationary installation 4 is made of the two wire rod folders 42 that are fixed on the link 41 on bracing frame 2 and be fixed on this link.Wherein the link two ends are provided with fixed block 411, and this fixed block is fastening by screw and bracing frame 2, and the degree of tightness of set screw slides up and down fixed block to control its position on bracing frame as required simultaneously; One end of two wire rod folders 42 is connected on link 41 and can moves left and right, and it is fastening by screw and link, and the other end is connected by screw fastening with test wire rod 5 one ends.
When testing; to test wire rod 5 upper ends is fixed on wire rod folder 42; end hangs up counterweight 35; counterweight below pallet 34 holds up and puts down by the power cycle of cylinder 33; the gravity constant by counterweight carries out tensile test to sample; auto stop after test number (TN) is completed guarantees that all the time fixedly strength ground carries out test fatigue lifetime to sample.Counterweight weight and stationary installation 4 to the distance of pallet can be regulated according to different products simultaneously.
Compared with prior art, the constant gravity of the utility model by counterweight has not only guaranteed to stretch consistent to the stress of sample to test fatigue lifetime of stretch of test wire rod at every turn, and emulation more realistically sample stress life in actual use; This device construction is simple, with low cost simultaneously, and practical operation is easy.
Above-described embodiment only is used for illustrating a kind of embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and variation, these distortion and variation all should belong to protection domain of the present utility model.
