Abstract
The invention discloses a clamping control device for a foil strip high-temperature tensile test. The device comprises a high-temperature tensile clamp with a square opening, wherein a sample is arranged at the middle part in the high-temperature tensile clamp; a pad is arranged between the sample and the inner wall on one side of the high-temperature tensile clamp; a step type pin penetrates in the lateral wall on the other side of the high-temperature tensile clamp, passes through the sample and the pad, goes out of the lateral wall on the other side of the high-temperature tensile clamp, and is fixed with a nut; and the sample is clamped by the shoulder surface of the step type pin and the pad on the other side. The clamping control device is convenient and easy in clamping, ensures close fit and better guarantees test result, so that the axial direction of the sample and the stress direction are consistent, system errors are reduced, the clearance between the sample and the pad is smallest, and the deformation degree of the pin hole of the sample is minimized.
Description
Technical field
The invention belongs to drawing by high temperature mechanical property detection technique field, relate to a kind of clamping control device that is used for paper tinsel band high temperature tension test.
Background technology
At present, domestic laboratory is carrying out band drawing by high temperature when test, for the better thin plate sample of plasticity (less than 1.5mm), and general being parallel-segment two ends band pin-and-hole or not being with two kinds of test samples of pin-and-hole of adopting.For the former, the sample between 1mm-1.5mm thickness uses pin that sample is connected with the drawing by high temperature anchor clamps, and adds Upper gasket respectively in sample pin-and-hole two sides, can satisfy the tension test standard-required basically.But for plasticity non-ferrous metal preferably; Because the good extension performance of material; Make that stress point is that the pin-and-hole position has produced local distortion in the drawing process of sample, some decomposes inoperative section (non-test section) to mean the test force value, causes the test findings deviation to increase.For not being with the pin-and-hole test sample; Relatively be applicable to the thinner paper tinsel band of material thickness less than 0.5mm; General use plane anchor clamps clamping sample two ends, loading are accomplished the tension test of sample, though the distortion of having avoided pin-and-hole to produce; But, receive force direction and sample to be prone to form a little angle owing to can accurately not guarantee to receive the center line of force direction and sample active section to be consistent.The power value of the power value of power value sensor determination and sectional area and reality and the ratio between the sectional area have produced deviation, still will directly influence the end value of test.In some important industry fields, this installation way will produce very adverse influence to the material mechanical performance test.
Summary of the invention
The purpose of this invention is to provide a kind of clamping control device that is used for paper tinsel band high temperature tension test, be applicable to the drawing by high temperature experiment of paper tinsel band, test result is accurate.
The technical scheme that the present invention adopted is; A kind of clamping control device that is used for paper tinsel band high temperature tension test; Comprise that opening is square drawing by high temperature anchor clamps; Drawing by high temperature anchor clamps bosom is provided with sample, is provided with pad between the side inwall of sample and drawing by high temperature anchor clamps, and the step pin penetrates from drawing by high temperature anchor clamps opposite side sidewall; Pass that the sidewall from drawing by high temperature anchor clamps opposite side passes and fixes through nut behind sample, the pad, the circular bead surface of step pin and the pad of opposite side grasp sample.
The invention has the beneficial effects as follows, convenient mounting and clamping, easily, guarantee to closely cooperate, test findings is more secure.Guarantee sample axially with receive force direction consistent, the minimizing systematic error.Guarantee that the gap is minimum between sample and the pad, reduce to the deformation extent of sample pin-and-hole minimum.Owing to adopted the step pin, the thickness of sample and pad can and the chucking opening width between bigger clamping spacing is arranged, sample can get into the clamping space easily, through screw threads for fastening, with sample and firm clamping of anchor clamps and location.If spacing is too big, then sample is in drawing process, and the lifting surface area that acts on power on the pin-and-hole reduces, and very easily makes the pin-and-hole plastic yield, influences the authenticity of test findings; If the gap is too little, sample will be difficult to smoothly clamping in the drawing by high temperature chucking opening, and conventional efficient reduces.Fastening nut can make sample and anchor clamps guarantee wringing fit, does not stay the gap.For the good thin test button of plasticity, the existence in gap must cause the distortion of pin-and-hole.Guarantee the spacer thickness consistent size of use, use to meet the sample that machine adds requirement, can eliminate the axial deviation that is produced with the direct clamping sample of drawing by high temperature anchor clamps.The opening size of drawing by high temperature anchor clamps is changeless, but the gauge of sample can be variant, adopts drawing by high temperature anchor clamps of the present invention, only need can guarantee one pair of pad, all can be suitable for different samples.

Among the figure, 1. straight formula pin, 2. pad, 3. sample, 4. drawing by high temperature anchor clamps, 5. nut, 6. step pin.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
The structure of existing clamping control device, as shown in Figure 1, comprise that opening is square drawing by high temperature anchor clamps 4, the both sides in the drawing by high temperature anchor clamps 4 are respectively arranged with in 2, two pads 2 of the identical pad of thickness and accompany sample 3; Straight formula pin 1 sidewall from drawing by high temperature anchor clamps 4 one sides penetrates, and passes pad 2, sample 3, pad 2 successively and afterwards passes through nut 5 fixing from the sidewalls of drawing by high temperature anchor clamps 4 opposite sides.
The structure of clamping control device of the present invention; As shown in Figure 2, comprise that opening is square drawing by high temperature anchor clamps 4, drawing by high temperature anchor clamps 4 bosoms are provided with sample 3; Be provided with pad 2 between the one side inwall of sample 3 and drawing by high temperature anchor clamps 4; Step pin 6 penetrates from drawing by high temperature anchor clamps 4 opposite side sidewalls, passes sample 3, pad 2 backs and passes through nut 5 fixingly from the sidewalls of drawing by high temperature anchor clamps 4 opposite sides, and the circular bead surface of step pin 6 and the pad 2 of opposite side grasp sample 3.
Sample clamping mould of the present invention only needs the consistent pad 2 of assurance one side used thickness, uses step pin 6 to cooperate an end nut 5 realizations to compress; Make sample 3 by clamping firmly in drawing by high temperature anchor clamps 4; Can realize clamping very easily, and guarantee that the gap is zero between sample 3 and the pad 2, guarantee that sample 3 is not having the space that is out of shape perpendicular to receiving on the force direction; Avoided the problem of stressed stage bore deformation; 6 thickness are identical because the step of a side is pinned simultaneously, guaranteed that sample 3 and power are coaxial, and sample 3 reverses when having avoided stretching.
The use of sample clamping mould of the present invention is; At first pad 2 and sample 3 are fitted, the hole of pad 2 is consistent with the hole site of sample 3, presses close in drawing by high temperature anchor clamps 4 openings by the position of pin-and-hole then; Step pin 6 penetrates pin-and-hole; And fastening with nut 5, an end sample clamping is accomplished, and the other end uses the same procedure clamping to accomplish.
