Abstract
The utility model discloses an aluminum alloy density tester, which comprises an electronic balance (1). The aluminum alloy density tester is characterized in that a detachable tray (2) is arranged above the electronic balance (1), a water cup (3) is arranged above the tray (2), and a test piece support (4) used for hanging test pieces is arranged on the electronic balance (1). The aluminum alloy density tester is simple in structure, low in cost, high in measuring precision and convenient in maintenance.
Description
Technical field:
The utility model relates to a kind of tester, and especially a kind of being applied in the metallurgy industry can be used for detecting the tester of the density of aluminium alloy.
Background technology:
When smelting aluminium alloy, if when the content of the hydrogen in the aluminium alloy and other impurity is higher, the performance of aluminium alloy is changed, be unfavorable for commercial production and application.Whether exceed standard in order to measure the hydrogen in the aluminium alloy and the content of other impurity, people tend to measure the density of the Al alloy block that is solid-state after the cooling, standard density with itself and aluminium alloy contrasts then, and when the density of tested aluminium alloy test block was lower than standard density, tested test block was just defective.The most complex structure of device of the measurement aluminium alloy test block density of generally using in this area cost an arm and a leg, and failure rate is higher now, causes the maintenance cost height, the problem that operation cost of enterprises, expenditure increase.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, with low cost, measuring accuracy height, aluminium alloy density tester easy to maintenance.
Technical solution of the present utility model is: a kind of aluminium alloy density tester, comprise electronic scales 1, it is characterized in that: be provided with removable pallet 2 above described electronic scales 1, the top of pallet 2 is provided with water tumbler 3, and the test block support 4 that is used to hang test block is placed on electronic scales 1.
The utility model is compared with prior art, has following advantage:
The utility model utilizes Archimedes's theorem dexterously, can measure tested fast density size apace, not only simple in structure, easy to operate, quick, and with low cost, maintenance cost is low, can reduce the operation cost of enterprise greatly, further improve the competitive power of enterprise in this area, this device possesses extensive market prospects, helps applying in the art.
Description of drawings:
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the side view of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of aluminium alloy density tester, comprise electronic scales 1, above electronic scales 1, be provided with removable pallet 2, the pallet top is provided with water tumbler 3, the test block support 4 that is used to hang test block is placed on electronic scales 1, and the suspension arm 5 of test block support 4 is positioned at the top of pallet 2 and water tumbler 3, and the tested test block 7 that hangs under the test block support 4 by suspension strop 6 (a kind of very thin stainless steel wire) is positioned at the water tumbler 3 that water is housed.
When needing to measure the density of tested aluminium alloy test block, at first on electronic scales 1, directly measure the weight G1 of tested test block 7, then pallet 2 is assembled, and the water tumbler 3 that will fill water is placed on the pallet 2, all immerse the tested test block 7 that is suspended on the suspension arm 5 under the liquid level of water tumbler 3, the weight that show on the electronic scales 1 this moment is test block support 4 and the weight sum that is subjected to the tested test block 7 after the buoyancy, because the weight of test block support 4 is known, therefore the weight that is subjected to the tested test block 7 after the buoyancy as can be known, and be designated as G3, and the buoyancy that is subjected to of tested test block 7:
G2＝G1-G3；
According to Archimedes' principle, G3=ρ
Water(V is the volume of tested test block 7 to V, ρ
Water=1000kg/m
3=1g/cm
3).The substitution following formula gets:
V＝G1-G3
Because G1=is ρ
AluminiumV, i.e. ρ
Aluminium(G1-G3)=G1
The final derivation draws:
ρ
Aluminium=G1/ (G1-G3)
Demonstration weight G3 after utilizing the actual weight G1 that this method can be by measuring tested test block 7 and being subjected to buoyancy can obtain the density value ρ of the Al alloy block of arbitrary volume
Aluminium, then with this density value ρ
AluminiumStandard density ρ with aluminium alloy
MarkCompare, if ρ
Aluminium＜ρ
Mark, the hydrogen in this tested test block 7 and the content overproof of other impurity then are described, on the contrary then qualified.
After utilizing the actual weight G1 of the tested test block that this device will extract and showing that weight G3 measures, directly calculate its density value ρ
Aluminium, and with standard density value comparison, realize detecting the purpose that whether hydrogen and other impurity contents exceed standard in the Al alloy block.
