The clamp plate adopt wooden material, plank thickness be 3cm -5cm, 2 times of more than or equal to sample width are wanted to the width, the comparatively accurate and easy operation of this test device tentation data is conveniently.

Description

A simple testing device for edge crush strength of aluminum alloy wheel packaging cartons

technical field

The utility model relates to an aluminum alloy wheel packaging carton, in particular to a simple edge pressure test device for an aluminum alloy wheel packaging carton. .

Background technique

There are many domestic aluminum alloy packaging carton factories, but there are only a few aluminum alloy packaging carton factories with complete inspection strength test equipment. Most aluminum alloy packaging carton factories use their own production experience to ensure customer requirements. In the past, the aluminum alloy wheel factory did not have a more accurate detection method for whether the strength of the carton used for packaging met the requirements. The purchase of test equipment for cartons will undoubtedly increase the cost of the product, which is not conducive to the competition of the product in the market, but if the strength of the aluminum alloy packaging carton is not tested, the potential risk will increase. To sum up, it is particularly important to low-cost test the strength of aluminum alloy packaging cartons to reduce potential risks.

Utility model content

The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, propose a kind of simple and easy aluminum alloy wheel packing carton side pressure strength inspection device.

The technical solution of the utility model: a simple inspection device for the side pressure strength of aluminum alloy wheel packaging cartons, the side pressure strength inspection device consists of a test bench (1), a fixed chuck (2), and a movable chuck (5) , a pressing plate (3) and a dynamometer (4). The test bench is provided with two stepped rectangular slides (7), and the fixed chuck (2) is a rectangular strip, which is fixed on the test bench (1) with bolts and pins for positioning. And ensure that the center line of the fixed chuck (2) is perpendicular to the center line of the stepped rectangular slideway (7) on the test bench (1), and the movable chuck (5) passes through the test bench (1) with bolts. The stepped rectangular slideway (7) is connected with it, so that the movable chuck (5) can move left and right through the slideway to complete the process of loosening and clamping the sample. The pressing board (3) is made of wood material, the thickness of the board is 3cm-5cm, and the width is greater than or equal to twice the width of the sample.

The utility model has the advantages that the side pressure strength testing device has a simple structure, is easy to operate, is easy to carry, and has relatively accurate measurement data. That is, the risk brought by the accessories is reduced and the cost is saved.

Detailed ways

Below in conjunction with accompanying drawing and example the utility model is further described.

Fig. 1 and Fig. 2 are a kind of simple edge compressive strength testing device of aluminum alloy wheel packaging carton, said edge compressive strength testing device consists of test bench (1), fixed chuck (2), movable chuck (5), Pressing plate (3) and dynamometer (4) are composed. The test bench (1) is provided with two stepped rectangular slideways (7), which are connected to the movable chuck (5) by bolts, in order to provide the movable chuck (5) with the movement of clamping or loosening. Space; the fixed chuck (2) is a rectangular strip, fixed on the test bench (1) with bolts to connect the pins, and ensure that the center line of the fixed chuck (2) is in line with the test bench (1) The center line of the upper stepped rectangular slideway (7) is perpendicular to each other; the pressure plate (3) is made of wood material, the thickness of the board is 3cm-5cm, and the width is greater than or equal to twice the width of the sample.

Loosen the bolts on the movable chuck so that it moves along the slideway of the test bench (1) away from the fixed chuck (2), and place the prepared sample (6) on one side of the fixed chuck (2) , move the movable chuck (5) to move closer to the fixed chuck (2) and touch the sample (6), and stop moving when the sample (6) is not damaged, and then tighten the clamp on the movable chuck (5). The bolts clamp the specimen tightly.

Place the pressure plate (3) on the upper surface of the sample (6), make the sample as far as possible in the center of the pressure plate (3), and then place the force gauge (4) on the pressure plate (3) to apply pressure until the sample (6 ) crush, read the value on the dynamometer, and then calculate the edge crush strength of the aluminum alloy wheel packaging carton according to the following formula.

Calculation formula of edge compressive strength: R=F/152;

In the formula, R--edge compressive strength, in KN/m; F--the force value read on the dynamometer when the sample collapses, in N; 152--the length of the sample, in mm.

The calculated R value is the edge compressive strength of the aluminum alloy wheel packaging carton submitted for inspection.
