Abstract
The utility model discloses a steel cord tensile test clamp used for a radial tire. The steel cord tensile test clamp comprises a clamp body (3), a winding wheel (10) and a clamping mechanism. The winding wheel (10) is arranged in a clamp body (3) and used for winding a steel cord, and the clamping mechanism is used for clamping the steel cord. The steel cord tensile test clamp is characterized in that the part, winding the steel cord, of winding wheel (10) is of an involute structure. The involute form winding wheel is adopted for enabling a steel core sample to approach to straightness at an outlet of the winding wheel, the shear force of the sample in the horizontal direction is reduced, the situation that in the process of testing, the sample fractures outside the clamp can be effectively guaranteed, and test accuracy is improved.
Description
Technical field
The utility model relates to the fixture that a meridian line tyre is used by steel cord tensile test.
Background technology
According to regulation in GB/T 11181-2003 " radial steel cord ", the steel cord is when doing the determination test of Fracture Force and Breaking elongation, sample can not be in fixture any part fracture, and steel cord sample should not produce slip in fixture, otherwise that test findings is all regarded as is invalid.
At present, doing the fixture that radial uses by the tensile test of steel cord is all to adopt circular reel, and the fixture of this structure easily causes sample to rupture in fixture at the trial, causes test findings to be judged as invalid, has affected the precision of test; In addition, doing at present this test is to adopt the hand-operated clamping sample mostly, and work efficiency is lower.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model provides a kind of steel cord tensile test fixture for radial that can improve test accuracy and work efficiency.
The utility model is achieved by the following technical solution: steel cord tensile test fixture for a meridian line tyre, comprise clamp body, be located in clamp body for the reel that is wound around the steel cord, for clamping the clamping device of steel cord, its special character is that the part that described reel is wound around the steel cord is involute urve shape structure.
The utility model adopts the evolvent type reel, can make steel cord sample level off in the reel exit position straight, has reduced sample shearing force in the horizontal direction as far as possible, and while effectively having guaranteed test, sample ruptures outside fixture.
For the reliable clamping that guarantees the steel cord and increase work efficiency, the clamping device for clamping the steel cord in the utility model adopts following structure: described clamping device comprises linkage assembly and clamp system, described linkage assembly comprises the push rod be arranged in clamp body, one end of described push rod is connected with the cylinder on being connected to clamp body, its other end is connected with a connecting rod, described clamp system is corresponding to the initiating terminal setting of the winding steel cord of reel, it comprises the large pivot pin be connected on clamp body, be connected with L shaped web joint on described large pivot pin, one of them wing plate of described L shaped web joint is connected with clamp by connected coupling shaft, another wing plate of described L shaped web joint is connected with the connecting rod of described linkage assembly.Can drive push rod action by cylinder, push rod drives L shaped web joint by connected connecting rod and rotates around large pivot pin, thereby L shaped web joint rotates and drives coupling shaft and promote the clamp action, thereby realization is to the clamping of steel cord or unclamp.
The beneficial effects of the utility model are: the utility model is by adopting involute urve form reel, can make steel cord sample level off to straight in the reel exit position, reduced sample shearing force in the horizontal direction, sample is difficult for rupturing in fixture, effectively sample ruptures outside fixture during warranty test, has improved the precision of test; In addition, the utility model is by adopting the mode of Pneumatic clamping, and safety and reliability when the clamping sample, can increase work efficiency greatly.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in drawings, steel cord tensile test fixture for one meridian line tyre, it comprises clamp body 3, be located in clamp body 3 for the reel 10 that is wound around the steel cord, for clamping the clamping device of steel cord, the part that described reel 10 is wound around the steel cords is involute urve shape structure.
The clamping device for clamping the steel cord in the present embodiment can adopt prior art.Reel 10 in the present embodiment can replace the circular reel in existing steel cord fixture.
For the reliable clamping that guarantees the steel cord and increase work efficiency, the utility model is on the basis of the reel 10 that adopts the involute urve form, clamping device adopts the Pneumatic clamping mode, its structure adopted is: described clamping device comprises linkage assembly and clamp system, described linkage assembly comprises the push rod 12 be arranged in clamp body 3 and the connecting rod 11 that is connected to push rod 12 1 ends, the other end of push rod 12 is connected with cylinder 4, and cylinder 4 is connected with clamp body 3 by flange.Described clamp system is corresponding to the initiating terminal setting of the winding steel cord of reel 10, it comprises the large pivot pin 7 be arranged on clamp body 3, be connected with L shaped web joint 6 on large pivot pin 7, one of them wing plate of described L shaped web joint 6 is connected with coupling shaft 8 by two little pivot pins 5, the other end of coupling shaft 8 is connected with clamp 9, clamp 9 is corresponding to the initiating terminal setting of the winding steel cord of reel 10, and another wing plate of described L shaped web joint 6 is connected with the connecting rod 11 of described linkage assembly.
Course of action of the present utility model is: cylinder 4 actions, drive push rod 12 and connecting rod 11 actions, connecting rod 11 drives connected L shaped web joint 6 thereupon and rotates around large pivot pin 7, L shaped web joint 6 drives coupling shaft 8 motions by little pivot pin 5 in rotation process, coupling shaft 8 promotes clamps 9 actions, thereby realizes the clamping of steel cord 14 or unclamp.
Other parts in the present embodiment adopt prior art, do not repeat them here.
