Abstract
The utility model relates to a clamping block for a steel wire tensile testing machine. The clamping block comprises a wedged base, a jaw, an anti-slip pressing block and a screw, wherein a rectangular through groove is longitudinally formed in the wedged base; the width of the rectangular through groove is the same as that of the jaw; the width of the upper notch of the rectangular through groove is one second of that of the rectangular through groove; the length of the upper notch is one sixth of that of the whole rectangular through groove; the jaw is mounted in the rectangular through groove in the wedged base; toothed textures are formed on the clamping working surface of the jaw; a groove is formed in the end surface of one side of the wedged base; a threaded hole is drilled in the bottom of the groove; the 7-shaped anti-slip pressing block is placed in the groove and connected with the wedged base through the screw; the jaw can be compressed by the anti-slip pressing block by screwing down the screw. The clamping block has the advantages that the clamping block can clamp a steel wire sample stably and reliably, is convenient to replace and disassemble, can effectively improve the work efficiency during testing, and saves labor.
Description
Technical field
The utility model relates to the clamp device that steel wire tension test is used, the wire clamp fixture block particularly using in tension test.
Background technology
In steel wire rope production, require on material stretch test machine, to do disrumpent feelings tension test, by reliable clamping sample, prevent from skidding, accurately obtain the technical parameters such as tensile strength, yield strength, extensibility, unrelieved stress, elastic modulus of material.
Traditional cupping machine all adopts full-height tooth chip fixture for the fixture at clamped wire two ends, because of its former design jaw size less, during clamped wire sample, effectively holding area is less, easily cause steel wire sample to skid in jaw, the clamping process of steel wire process of the test is repeated, reduced test efficiency, in addition, effectively holding area is very few, easily steel wire sample is formed to larger compressive stress, easily damage test steel wire sample is held position and causes the disconnected jaw of test steel wire sample, causes unnecessary invalid test.Meanwhile, former cupping machine does not arrange the anti-shedding mechanism of jaw, has the situation that jaw comes off to occur in the time of in the operation of testing.Obviously, traditional fixture at the trial, exists test figure inaccurate, and the retrial operation of need to resampling is loaded down with trivial details, the low shortcoming with expending a large amount of valuable human resources of test efficiency.
Summary of the invention
The deficiency that the utility model exists for prior art, provide a kind of clamped wire sample reliable and stable, change convenient disassembly, the steel wire cupping machine fixture block of effectively lifting test work efficiency, and saving manpower.
The utility model is achieved through the following technical solutions: a kind of steel wire cupping machine fixture block, comprise wedge type base, jaw, anticreep briquetting and screw, described wedge type base longitudinally arranges rectangle groove along it, the width of this rectangle groove is identical with the width of described jaw, and the upper gap width of this rectangle groove is 1/2nd of groove width, upper breach accounts for the sixth of groove; Described jaw is arranged in the rectangle groove on wedge type base, and jaw clamping working surface arranges groove; Notch is offered in one side end face of wedge type base, and notch bottom is drilled with threaded hole, places " 7 " font anticreep briquetting in notch, and anticreep briquetting and wedge type base are connected by screw, and tightens screw and can make anticreep briquetting compress jaw.
Further scheme is the bidentate line that the groove that arranges on jaw is cross arrangement, bidentate line is comprised of end tooth and face tooth, its structure is by two different directions, groove to be set along jaw axis, and end tooth and jaw axis angle are 40～45 °, and face tooth and jaw axis angle are 60～65 °; Described fixture block material adopts carbon tool steel, and hardness is between 55～60HRC.
The beneficial effects of the utility model are: the rectangle groove arranging on described wedge type base, can effectively increase the effective holding area of fixture block to steel wire on the one hand, the compressive stress of minimizing to steel wire test, avoid fixture pinch off steel wire, cause the disconnected jaw phenomenon of steel wire sample, can improve on the other hand the adaptability that different jaws are used, the upper breach of groove is convenient to steel wire and is entered jaw clamping, and associated jaw portion is easy to change, convenient disassembly.The bidentate line that the working surface of jaw clamping simultaneously arranges, and fixture block employing carbon tool steel material, hardness can reach 55～60HRC, and clamping steel wire sample, greatly improves the Stability and dependability of test preferably.And the setting of anticreep briquetting effectively prevents coming off of jaw, thereby promote on the whole the work efficiency of steel wire tension test, saved manpower.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to structural representation;
In figure: 1. wedge type base, 2. jaw, 3. anticreep briquetting, 4. screw, 5. goes up breach, 6. groove, 7. rectangle groove, 8. notch, 9. end tooth, a 10. tooth, α. end tooth and jaw axis angle, β. face tooth and jaw axis angle.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
The utility model specific embodiment is: a kind of steel wire cupping machine fixture block, comprises wedge type base 1, jaw 2, anticreep briquetting 3 and screw 4.
Described wedge type base 1 longitudinally arranges rectangle groove 7 along it, and the width of this rectangle groove 7 is identical with the width of described jaw 2, and upper breach 5 width of this rectangle groove 7 are 1/2nd of groove widths, and upper breach 5 accounts for the sixth of groove;
Described jaw 2 is arranged in the rectangle groove 7 on wedge type base 1, and jaw 2 clamping working surfaces arrange groove 6; Notch 8 is offered in one side end face of wedge type base 1, and notch 8 bottoms are drilled with threaded hole, the interior placement of notch 8 " 7 " font anticreep briquetting 3, and anticreep briquetting 3 is connected by screw 4 with wedge type base 1, tightens screw 4 and can make anticreep briquetting 3 compress jaw 2.
The groove 6 arranging on described jaw 2 is the bidentate line of cross arrangement, bidentate line is comprised of end tooth 9 and face tooth 10, its structure is by two different directions, groove to be set along jaw 2 axis, and end tooth 9 is 40～45 ° with jaw axis angle [alpha], and face tooth 10 is 60～65 ° with jaw axis angle beta.
Described fixture block material adopts carbon tool steel, and hardness is between 55～60HRC.
Further instruction is that, during test, fixture block comprises wedge type base 1, jaw 2, anticreep briquetting 3 and screw 4, jaw 2 is put into the rectangle groove 7 of wedge type base 1, tighten screw 4, anticreep briquetting 3 is compressed to jaw 2, then fixture block is packed in clamp of stretching tester.Setting due to rectangle groove 7 on wedge type base 1, effective working area of jaw 2 clamped wire is increased, and jaw 2 working surfaces arrange bidentate line, the Stability and dependability of clamped wire in the time of can effectively improving test, also improved the adaptability that different jaws are used, be convenient to the installation and removal of jaw 2 simultaneously.And the setting of anticreep briquetting 3 effectively prevents coming off of jaw 2, thereby promote on the whole the work efficiency of steel wire tension test, saved manpower.
