Abstract
The invention provides a titanium wire material elasticity detection method characterized by accurate detection, high efficiency and easy popularization and an elasticity detection device characterized by simple structure and convenient operation. The elasticity detection method includes: utilizing the simple elasticity detection device to fix one end of a titanium wire material specimen, bending the specimen by 90 degrees around a cylindrical support seat with a specified diameter, then loosening the specimen and letting the specimen rebound to a starting position automatically, measuring and calculating the offset distance of the specimen after multiple bending, and acquiring the elastic property inspection conclusion according to the offset distance and formulated titanium wire material elastic property inspection standards. The elasticity detection device is mainly composed of the following 6 parts: a fixation clamp block, a fastening clamp block, the cylindrical support seat, a bending arm, a pull rod, and a scale. The method and the device provided by the invention are suitable for detecting the room temperature elastic properties of titanium wire materials with a diameter or section thickness of 0.2mm-7mm.
Description
Technical field
The present invention relates to a kind of titanium silk material elastomeric check method and device.
Background technology
Titanium or titanium alloy material has good elasticity because elastic modulus is low, be applied to the various flexible members in the fields such as commodity, sports goods, engineering articles for use, making correcting shape of tooth, spectacle frame, earphone suspension member, coil tension spring, golf club impact the products such as panel.
The detection of titanium silk material elastic performance has two kinds of methods, and a kind of is to adopt special inspecting equipment to detect the elastic modulus of material, and which testing result is accurate, but its expense is high, complicated operation, time are long, need to have the personnel of professional qualification to detect; Another kind is to adopt hand vice to break curved to titanium silk material sample one or many, break curved after and sample contrast degree of crook, the bright good springiness of degree of crook novel, the large explanation poor flexibility of degree of crook, easy to operate, the directly perceived differentiation of which, efficiency are high, but its operation is random, human factor impact is large, can not accurately measure elastic performance, and result is also difficult to record and contrast.
Summary of the invention
In order to solve the deficiency existing in existing detection method, the object of this invention is to provide a kind of simple in structure, easy to operate, detect accurately, be conducive to improve the titanium silk material elastomeric check method of detection efficiency.
Elastomeric check method of the present invention is to utilize easy elastomeric check device, manually one end of titanium silk material sample is fixed, cylinder bearing 90-degree bent around specified diameter unclamps, sample appliance for releasing single is got back to reference position, the offset distance of measurements and calculations sample after bending repeatedly, according to offset distance and the titanium silk material elastic performance test stone of working out, draw the conclusion of elastic performance check.
Elastomeric check device of the present invention is mainly by fixedly fixture block, clamp block, cylinder bearing, bend arm, dead man, scale six parts form.The General Requirements of elastomeric check device: cylinder bearing and fixture block should have enough hardness, cylinder bearing should be replaceable.Cylinder bearing axis should be perpendicular to plane of bending, and coaxial with the center of rotation of bend arm.Sample effectively contacts with the arc surface of cylinder bearing when guaranteeing to test, and should regulate cylinder bearing central shaft, and sample is contacted with the arc surface of cylinder bearing.
The present invention is applicable to diameter or section thickness is the detection of 0.2mm~7mm titanium silk material room temperature elastic performance.
Titanium silk material of the present invention detects the specimen length 200~300mm of intercepting, the cylinder bearing diameter 15~105mm of elastomeric check device, and cylinder bearing axis is to the parallel distance 100~150mm at dead man center.Titanium silk material specimen finish or section thickness, cylinder bearing diameter and cylinder bearing center should meet the requirement of table 1 to the parallel distance at dead man center, unit millimeter.
Table 1 titanium silk material sample and the requirement of elastomeric check plant bulk.
The implementation step of elastomeric check method of the present invention.
1, choosing titanium silk material sample should be straight, allows slight bending in its plane of bending.
2, dead man, in plumbness, through dead man center pit, records the initial position of place, upper end scale by sample upper end, clamps sample lower end.
3, by sample from reference position 90-degree bent to the right, lift bend arm, sample appliance for releasing single is got back to reference position, as the 1st bending operation; BENDING PROCESS should be carried out with the uniform rate that is no more than 3 seconds at every turn, should be steadily without impact when crooked, while automatically rebounding without constraint.
4, with reference to the 2nd step, carry out the 2nd bending and rebound, as the 2nd bending operation.
5, with reference to the 2nd step, can carry out repeatedly bending operation.
6, repeatedly after bending operation, the ultimate position of recording place, sample upper end scale, the offset distance of last measurements and calculations and initial position.
7,, according to the offset distance of the 5th step and the titanium silk material elastic performance test stone of working out, draw the conclusion of elastic performance check.
