Abstract
The utility model relates to a testing apparatus for testing a creep property of cushioning materials, which is characterized by comprising a support, a guide pillar, a weight stand, a fixing bar and a dialgage. The support is composed of an upper steel plate, a lower steel plate and a supporting pillar fixed between the upper steel plate and the lower steel plate. A circular guide hole is arranged in the center of the upper steel plate. A pressing plate is arranged inside the support, and the center of the pressing plate is fixedly connected with the guide pillar. The guide pillar extends upwards to stretch out the upper steel plate through a guide tube and the guide hole. The weight stand is fixed on the guide pillar stretching out the upper steel plate, a fixing bar is fixed on the support, the fixing bar extends upwards to be higher than the guide pillar, and the dialgage is fixed on the fixing bar. The support, a pressing slice, the guide pillar and the like can fully guarantee that a center of gravity of a weighting block is vertical and downward, and can be evenly exerted on surfaces of materials to be tested, so that the creep of packing materials under specified weight can be actually indicated, and the precision of a testing is guaranteed.
Description
Technical field
The invention belongs to padded coaming performance test field, particularly a kind of padded coaming croop property tester for testing.
Background technology
Creep: solid material is keeping under the constant condition of stress, and strain prolongs and the phenomenon that increases in time.It is different with plastic yield, and plastic yield just occurs after stress surpasses limit of elasticity usually, and that creep needs only the action time of stress is quite long, and it also can occur during less than limit of elasticity at stress.
The croop property test of cushioning material for packing, it is one of big event to the wrappage assessment, the method of testing of current packaging padded coaming is: detected materials is placed in the chest, the breeding piece of predetermined weight lies in the detected materials upper surface, after the static placement stipulated time, measure the deformation height of detected materials, calculate its creep rate then.The weak point of this method is embodied in: after the breeding piece is placed on the detected materials, if chest produces mobile or vibration slightly, the center of gravity of breeding piece will be offset, cause the detected materials unbalance stress, deformation quantity can not accurately embody creep compliance in its true environment, the error that finally causes measuring becomes big, and it is inaccurate to measure numerical value, influences its use.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of measuring accuracy high padded coaming croop property tester for testing, this device can satisfy the testing requirement under the different counterweight conditions.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of padded coaming croop property tester for testing, comprise support, guide pillar, counterweight platform, fixed bar and dial gauge, at internal stent pressing plate is arranged, fixedly connected with guide pillar in the pressing plate center, guide pillar is upward through rack upper surface, stretches out the guide pillar fixed weight platform of upper surface, on support, be fixed with fixed bar, fixed bar extends upward and is higher than guide pillar, flexibly connects connecting link at fixed bar, and the connecting link end is dial gauge fixedly.
And described support is made up of upper and lower two steel plates and the support column that is fixed between the upper and lower steel plate, and the upper steel plate center is shaped on circular guide holes.
And described guide hole bottom is fixed with a bit of cylindrical guide.
And, do not contact with supporting around the described pressing plate.
Advantage of the present invention and beneficial effect are:
1, the measuring accuracy height of this padded coaming croop property tester for testing satisfies the testing requirement under the different counterweight conditions fully, functions such as record deflection.
2, structures such as the support in this croop property tester for testing, compressing tablet, guide pillar have guaranteed that fully the center of gravity of balancing weight is for vertically downward, and be applied to the detected materials upper surface uniformly, can be reflected at the creep compliance of wrappage under the predetermined weight really, guarantee the accuracy of test.
3, the replacing of the balancing weight of this croop property tester for testing is very convenient, is fit to test of many times repeatedly, effectively saves time.

Fig. 2 is the side view of Fig. 1.
Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of padded coaming croop property tester for testing, mainly comprise support, guide pillar 5, counterweight platform 4, fixed bar 1 and dial gauge 2, its medium-height trestle is made up of upper and lower two square plates 6,11 and the support column 10 that is fixed between four jiaos of the upper and lower steel plates, lower steel plate is a base, the upper steel plate center is shaped on the circular guide holes (not shown), be fixed with a bit of cylindrical guide 7 in the guide hole bottom, be used for auxiliary fixing; At internal stent one pressing plate 8 is arranged, and pressing plate around do not contact with supporting, fixedly connected with guide pillar in the pressing plate center, guide pillar upwards passes through the guide and the guide hole of upper steel plate, and does not contact with the two, under the pulling of guide pillar, pressing plate can freely move up and down in support; Fix a square counterweight platform at the guide pillar that stretches out upper steel plate, guide pillar is in the center of square counterweight platform, suit balancing weight 3 according to the rules on the guide pillar above the counterweight platform.Also fix a fixed bar on support, fixed bar extends upward and is higher than guide pillar, flexibly connects connecting link 1-1 at fixed bar, and the connecting link end is dial gauge fixedly, is used to measure the falling head that wrappage 9 produce the deformation BB1.
The principle of work of this padded coaming croop property tester for testing is:
Detected materials is placed between lower steel plate and the pressing plate, balancing weight is placed on the counterweight platform, measure the starting altitude h1 of guide pillar then with dial gauge, and it is noted, after when preventing fixedly, detected materials produces deformation, and the guide pillar height descends, measure its height h2 with dial gauge again, be the creep height of detected materials with h1-h2.
