The device provided by the invention can be used for measuring the hardness of materials; and the device is simple to operate and low in equipment cost.
Description
Technical field
The present invention relates to technical field of measurement and test, particularly the hardness test technology and equipment.
Background technology
In prior art, measure the hardness of material and mainly use sclerometer, comprise Brinell tester and Vickers.Measure the hardness of material with sclerometer, technical sophistication, and sclerometer is expensive.
In addition, be used for the interconnection belt (being coated with the interconnection belt in the tin copper strips) of photovoltaic battery panel, very soft when copper strip surface scribbles ashbury metal, need not measure soft or hard, but will measure the hardness of core copper, get and first the ashbury metal coating is removed, this operation is required great effort time-consuming very much, but also needs the specialty chemical talent.Because the hardness of interconnection belt is high, during welding, the fragment rate of silicon cell is just large, so manufacturer and use business just propose the ultra-soft interconnection belt.Does but how this differentiate the soft or hard of interconnection belt? general manufacturer and use the commercial city to have no idea to detect.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, design a kind of preparation facilities of strip projectile body, and measure the hardness of material with it, thereby set up a kind of platform of hardness of new measurement material.Measure the hardness of material with device of the present invention, technology is simple, and is with low cost.
The preparation facilities of strip projectile body of the present invention, said device has a former (1), and former (1) can be monoblock type, can be also left and right two Semi separation types, be used for regulating the magnitude of interference, the upper end of former (1) has groove, the left end sealing of groove, right-end openings, lay in groove by measuring tape (2), be fixed with flexure strip (4) on the internal chamber wall of former (1), there is a supporting plate (5) lower end of former (1), plays fixedly former (1) and flexure strip (4); The top of former (1) is outstanding a drift (3), and its thickness is B; Former has rectangular opening on (1), width is more than or equal to by the width of measuring tape (2), thickness B ' be less than B+2 is doubly by the thickness of measuring tape (2), the length of drift (3) want can gone out by measuring tape (2) form after former (1) have angle α by measuring tape (2).
Said flexure strip (4) can be bonding or be screwed on former (1) internal chamber wall, and the material of flexure strip (4) can be rubber or have flexible plastic sheet.
The purposes of the preparation facilities of strip projectile body of the present invention, can be used for measuring the hardness of material, its method is with punch press or manual depression drift (3), to be gone out former (1) by measuring tape (2) to the P direction, go out after former (1) by measuring tape (2) due to its rebound effect form a U font or the large opening of V font by measuring tape (2), its angle (springback angle) is α, then according to " hardness-α angular dependence curve " and/or " hardness-α angular dependence table " set up the in advance size by measurement α angle, can determine the hardness of material.
Compared to the prior art, the present invention has following beneficial effect.
1, measuring technique is simple, is easy to grasp.
2, the device preparation cost is low, can greatly reduce expenses.
3, surveying work fast, save time.
Description of drawings
Fig. 1 is the elevational cross-sectional view of apparatus of the present invention, and Fig. 2 is the vertical view of apparatus of the present invention (Fig. 1).
Embodiment
Also the invention will be further described by reference to the accompanying drawings below by embodiment.
As shown in Figure 1, 2, in figure, 1 is the monoblock type former, and 2 is the tin-coated copper strip of 0.2 * 1.6mm specification, and the copper base material is T1Cu, 99.95% purity, and thickness 0.153mm, strip two surfaces are coated with the Sn solder alloy.Be cut into 50mm and put into groove on former 1 after long, left end pushes up the step place.3 is drift, and 4 is flexure strip, selects the thick vacuum rubber of 5mm, and wide 15mm sticks with glue on the internal chamber wall of former, and the thickness of B is 8mm.B ' is also that 8mm is wide, and interference 0.306mm, H are 68mm; 5 is supporting plate, is positioned at the former lower end.
Press low punch with punch press and press the P arrow direction, movement velocity 16mm/min, the drip molding that is washed into is 15o by the α angle of measuring tape 2.30 of same condition punchings, the α angle of measuring is all 15o.
Embodiment 2:
Basic identical with the situation of embodiment 1, just more abundant the annealing of copper base material, press drift with manual mode.Other condition is constant, and the springback angle α that records is 10o.
Embodiment 3:
Basic identical with the situation of embodiment 1, just the copper base material trade mark is T2(999% purity), the same T1 of the annealing conditions of copper, other condition is also with example 1, and the drip molding of going out is become 20o by the α angle of measuring tape 2.
By above-mentioned example, two conclusions are described: the one, along with the purity raising of copper base material, under same annealing conditions, the α angle can diminish; The 2nd, the purity of copper base material changes to 99.99% by 99.95% and can reflect from springback angle α value.
