Therefore, for overcoming the deficiency of above-mentioned technology, design and can draw elasticity to test detection to the bending resistance of waterproof roll, flexible technical indicator is drawn in the bending resistance of grasping coiled material in time, elasticity modulus test device is drawn in a kind of waterproof roll bending resistance that guarantees product quality, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of waterproof roll bending resistance and draws elasticity modulus test device, it is simple in structure, easy to use, can draw elasticity to test detection to the bending resistance of waterproof roll, flexible technical indicator is drawn in the bending resistance of grasping coiled material in time, guarantees product quality, has extraordinary practical value.
The utility model solves the technical scheme that its technical matters adopts: elasticity modulus test device is drawn in a kind of waterproof roll bending resistance, it is characterized in that: device comprises removable bearing, loading bearing, clock gauge, dial indicators rack, screw rod, hold-down support, pressing machine, described clock gauge is arranged on dial indicators rack, dial indicators rack is metal rigidity framework, center is clock gauge socket, there are three round end screw rods at two ends, dial indicators rack top is provided with loading bearing, and loading bearing upper end is provided with pressing machine.
Further, described dial indicators rack bottom is provided with removable bearing.
Further, described dial indicators rack bottom is provided with hold-down support, and the top of hold-down support is conical.
Further, described clock gauge scale division value is 0.001mm, a kind of in 0 grade or l level.
The beneficial effects of the utility model are:
1, by using this device to draw elasticity to test detection to the bending resistance of waterproof roll, grasp in time the bending resistance of coiled material and draw flexible technical indicator, guarantee product quality, have extraordinary effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-coiled material test specimen; The removable bearing of 2-; 3-loading bearing; 4-clock gauge; 5-dial indicators rack; 6-screw rod; 7-hold-down support; 8-pressing machine.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1 is that elasticity modulus test apparatus structure schematic diagram is drawn in a kind of waterproof roll bending resistance of the utility model, device comprises removable bearing 2, loading bearing 3, clock gauge 4, dial indicators rack 5, screw rod 6, hold-down support 7, pressing machine 8, described clock gauge 4 is arranged on dial indicators rack 5, dial indicators rack 5 is metal rigidity framework, center is clock gauge socket, there are three round end screw rods 6 at two ends, and dial indicators rack 5 tops are provided with loading bearing 3, and loading bearing 3 upper ends are provided with pressing machine 8; Dial indicators rack 5 bottoms are provided with removable bearing 2; Dial indicators rack 5 bottoms are provided with hold-down support 7, and the top of hold-down support 7 is conical; Clock gauge 4 scale division values are 0.001mm, a kind of in 0 grade or l level.
The utility model is waited in use, when testing the length of time, takes out coiled material test specimen 1, with wet cloth, covers, and avoids its humidity to change.Remove coiled material test specimen 1 surperficial dirt, coiled material test specimen 1 part that equating contacts with device, in coiled material test specimen 1 top and bottom, mark center line and setting position line, at dial indicators rack 5 totally four pin point places, with dry towel, first dry moisture, with 502 glue, cement little glass sheet again, measure width and the height at coiled material test specimen 1 middle part, be accurate to 1mm.
Coiled material test specimen 1 is placed on bearing; side while making moulding upward; dial indicators rack 5 is placed on coiled material test specimen 1; pressure head and support wire, perpendicular to coiled material test specimen 1 center line and load condition without acceptance of persons, then slowly add about 1KN pressure by pressing machine 8, and each seam crossings such as shutdown inspection bearing have tight; need if desired to add metal shim; should guarantee that test specimen does not twist, clock gauge 4 is then installed, its contact and dial framework contact surely stand on little glass sheet.
Get bending resistance and draw half of ultimate load mean value, for bending resistance, draw the load standard of elasticity modulus test, carry out adding for 5 times and unload load circulation, by lKN, risen, with the speed loading of 0.15KN/s～0.25KN/s, to 3kN scale place, shut down, keep about 30s, in asking when this section of loading, clock gauge pointer should be able to start, otherwise should improve F0 to 4KN etc., write down clock gauge reading, then continue to add to F0.5, keep about 30s, write down clock gauge reading; Off-load, to lKN, keeps about 30s at the same rate again, is circulation for the first time.
With circulation for the first time, carry out altogether five circulations, the deflection value of getting the 5th circulation is as the criterion, when last circulation complete, after checking that each reading is errorless, remove immediately clock gauge, continue loading until test specimen fractures, write down the rear bending tensile strength of circulation, observe rupture surface shape and position, the mid-span deflection formula inverse that the bending resistance of coiled material draws elastic modulus respectively to add load etc. by free beam in three branches is tried to achieve, by using this device to draw elasticity to test detection to the bending resistance of waterproof roll, flexible technical indicator is drawn in the bending resistance of grasping coiled material in time, guarantee product quality, there is extraordinary effect.
