Abstract
The utility model relates to a tension tester for thin plates and belts, particularly a clamp for the stretching test of super thin plates and belts. The clamp for the stretching test of the super thin plates and the belts is characterized in that the clamp comprises two screw bolts and screw nuts, wherein the screw bolts are composed of screw nuts and screw rods. The screw rod of the first screw bolt is pivoted with two screw nuts, and the screw rod of the second screw bolt is provided with an inner hole which is provided with an inner screw thread. The second screw rod is pivoted with the first screw rod. A sample is clamped by the top of the second screw rod and the screw nuts pivoted with the first screw rod. Pin holes of draw rods of a stretching machine are sheathed with the first screw rod and the second screw rod. The top of the second screw rod is welded with the screw nut. The utility model has the advantages of simple structure and convenient operation. In addition, the extrusion stress from pins of the stretching machine to pin holes on the sample thin plates and the belts can be eliminated, and the purpose of the conventional stretching test carried out by the stretching machine for the thin plates and the belts can be achieved.
Description
(1) technical field
The utility model relates to thin plate band cupping machine, relates in particular to be used for the anchor clamps of strip tension test as thin as a wafer.
(2) background technology
An important mechanical performance index of metal is a tensile strength, and tensile strength generally draws by tension test.Existing cupping machine generally can only be done the tension test of above sheet coupon of 1mm or column sample.The sheet material tensile sample as shown in Figure 1.During stretching, tensile sample is vertically placed the centre of lower link, with pin with sample respectively with pull bar pinning up and down, starter motor makes the pull bar relative motion then, is broken up to sample.According to general knowledge, the position that sample is broken should be at the parallel zone at sample middle part, because suffered herein tension maximum.The shape and size requirement that general cupping machine has all been stipulated tensile sample under the different-thickness situation.Yet, for the as thin as a wafer strip of thickness less than 0.5mm, owing to exceeded the size of sample scope of general cupping machine, therefore be difficult to determine the requirement of specimen size, and the thin plate band tensile sample of the 0.5mm that is processed with reference to the thick sheet coupon size of 1mm, in same process of the test, because the tension that bear at sample pinhole place is much larger than the suffered tension of sample middle part parallel zone, thereby the beginning back pinhole that causes stretching at first is out of shape, drawn back until pinhole, caused whole tension test failure.
(3) summary of the invention
The purpose of this utility model is to provide a kind of anchor clamps of strip tension test as thin as a wafer that are used for, this clamp structure is simple, easy to use, can eliminate the extrusion stress of drawing machine pin to pinhole on the thin plate band sample, realize utilizing conventional drawing machine to carry out the purpose of strip tension test as thin as a wafer.
The utility model is achieved in that a kind of anchor clamps of strip tension test as thin as a wafer that are used for, it is characterized in that comprising two screw bolt and nut, bolt is made up of nut and screw rod, be rotary with two nuts on the screw rod of first bolt, the screw rod of second bolt has endoporus, has internal thread on the endoporus, and the second screw rod cover is spun on first screw rod, the second screw rod top and the nut that is spun on first screw rod are clamped sample, and drawing machine pull bar pin borehole jack is contained on first screw rod and second screw rod.
The above-mentioned anchor clamps of strip tension test as thin as a wafer that are used for, the described second screw rod top is welded with nut.
The utility model is by increasing anchor clamps to strip as thin as a wafer, when plate carries out tension test as thin as a wafer, what sample pinhole place was subjected to no longer is the extrusion stress of pin, but nut is to the friction force of sample face clamping, thereby the weak area that sample is stressed is transferred to the parallel zone at sample middle part, has guaranteed the validity of thin plate band tension test.The utility model clamp structure is simple, easy to use, can eliminate the extrusion stress of drawing machine pin to pinhole on the thin plate band sample, prevent the stretcher strain of pinhole place, make pulling force really affact the parallel zone of sample, realize utilizing conventional drawing machine to carry out the purpose of strip tension test as thin as a wafer.
(4) description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a sheet material tensile sample synoptic diagram.
Fig. 2 is used for the clamp structure synoptic diagram of strip tension test as thin as a wafer for the utility model;
Fig. 3 is a thin plate band tension test synoptic diagram.
Among the figure: 1 first nut, 2 first screw rods, 3,4,5 nuts, 6 second screw rods, 7 second nuts, 8 upper connecting rods, 10 tensile samples, 11 lower links, 12 anchor clamps.
(5) embodiment
Referring to Fig. 2, Fig. 3, a kind of anchor clamps 12 that are used for strip tension test as thin as a wafer comprise two screw bolt and nut, and bolt is made up of nut 1,7 and screw rod 2,6.The screw rod 6 that is rotary with two nut 3,4, the second bolts on the screw rod 2 of first bolt has endoporus, has internal thread on the endoporus; Second screw rod, 6 covers are spun on first screw rod 2, and tighten, and second screw rod, 6 tops and two nuts 3,4 that are spun on first screw rod 2 are clamped sample 10, and nut 3,4 is close to mutually.Drawing machine pull bar pin borehole jack is contained on first screw rod 2 and second screw rod 6.Second screw rod, 6 tops can be welded with nut 5, by the nut on the nut 5 that is fixed in second screw rod, 6 tops and first screw rod 23,4 sample 10 are clamped.
Referring to Fig. 3, when the strip tensile sample is installed as thin as a wafer, pass the slits place of drawing machine one side pinhole after earlier first screw rod 2 being screwed on two nuts 3,4 to upper connecting rod 8 centres, to as thin as a wafer from the slit of upper connecting rod 8 centres then, strip tensile sample 10 is through on first screw rod 2, the pin borehole jack that again second screw rod 6 is passed upper connecting rod 8 opposite sides is spun on first screw rod 2, tightens mutually by first nut 1 and second nut 7.Be fixed in like this second screw rod, 6 tops nut 5 and by two nuts 3,4 be fixed on first screw rod 2 nut 4 as thin as a wafer strip tensile sample 10 clamp.The anchor clamps installation method of lower link 11 is identical with upper connecting rod 8, so just tensile sample 10 firmly is fixed on upper and lower pull bar 8,11 centres, has realized the tension test of strip as thin as a wafer of adopting conventional drawing machine to carry out.
Adopt the tension test under the different temperatures that anchor clamps of the present utility model carry out thickness 0.2-0.5mm strip sample, drawn satisfied result.
