Description
Technical field
The utility model belongs to rubber checkout equipment technical field, is specifically related to a kind of rubber air oven aging test case.
Background technology
Existingly carry out the ageing oven of aging test for materials such as rubber, plastics, PVC, its structure comprises a casing with heat-insulation layer, be arranged on air inlet on casing one sidewall, one for sending into blower fan in casing, air heat that can the make inlet heating tube to aging test temperature by outside air from air inlet, and be contained in the rotating disk being driven by mechanical transmission mechanism by motor in casing, the using method of this ageing oven is, first material to be tested is put on rotating disk, then starts blower fan and motor; At this moment outside air enters casing from air inlet, and reaches material aging through heating tube heating and test required temperature; In this simultaneously, rotating disk is reached and is maintained in test temperature by the heat of air in mechanical transmission mechanism slow rotation, the continuous respiratory box of material to be tested, to treat the aging variation of people's observation period.
Because aging test requires highlyer to the uniformity coefficient of space temperature in case, that is require in case temperature uniformity everywhere, otherwise on same material by there is different aging conditions, cannot obtain the accurate data of material aging test; For this reason, existing ageing oven is that rotating disk is installed in case, reach temperature on test material by rotating disk even; But not ideal from experiment showed, the effect of rotating disk, therefore the aging test accuracy of existing ageing oven is also nonconforming; Secondly, bring uncertain or unsafe factor due to the existence of rotating disk to aging test, also can there is different degree of agings because of the difference of its residing rotating disk radial location in each on same material point for example, and in the start-up course of rotating disk, material to be tested not only can be on rotating disk from line slip, change its original position, but also likely from rotating disk, slippage is out; Again, because rotating disk occupies the large percentage in space in case, the space that can carry out aging test for material is reduced, therefore the work efficiency of ageing oven is lower, and wearing and tearing and the obstacle of zero of dial rotation, also can increase the line service amount of chamber.
In addition, in elastomeric material physical property detects, thermal aging property rate of change project need to be heat-treated tensile bars, and traditional ageing oven is difficult to realize.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of rubber air oven aging test case, and aging temperature is even, and can realize accurately the thermal treatment of tensile bars.
The problem existing for solving above-mentioned prior art, the technical scheme that the utility model is taked is: rubber air oven aging test case, comprise casing, chamber door, be positioned at the controller of casing one side, it is characterized in that, in casing, comprise chamber, described chamber is surrounded by heat-insulation layer outward, and described chamber and heat-insulation layer are provided with the air hole communicating; Between heat-insulation layer and casing, be hot-flow flue, be positioned at heat-insulation layer both sides and be respectively equipped with heating tube in described hot-flow flue, one end relative with heating tube is provided with blower fan; In described chamber, shaft position is provided with two rotation axiss, and the periphery of each rotation axis is evenly provided with one group of rubber grip block, and described rubber grip block is provided with clamping part, and described rotation axis connects motor.
The position of described chamber inwall air hole is also provided with cover plate, and described cover plate one side is fixed on chamber inwall, and in the time ventilating, cover plate is opened because of wind-force effect, and hot blast enters, and due to the guide effect of cover plate to hot blast, is conducive to hot air circulation in chamber; In the time of insulation, wind-force stops, and due to internal heat air pressure, cover plate is closed, and avoids hot blast to flow out and loses.
The distance of adjacent described clamping part is 10mm-40cm, preferably 20mm-30cm.
Described clamping part is welded on rubber grip block.
Described chamber door is provided with view window.
Described ageing oven is also provided with LCDs, for showing the information such as test parameters.
Described chamber door is provided with handle.
The thermal aging test machine that rubber air oven aging test case described in the utility model is evaluated thermostability and heat-resistant aging by adding hot-air, temperature is even, and the term harmonization of can warranty test material accepting by rotation grip block, pass through clamping action, test material can slippage, and can do tension test, the setting of two groups of grip blocks, takes full advantage of space.The satisfied testing standard of the utility model has JIS-A5756, B7757, C3005, K6257, K6723, K7212, ASTM-D573, D2436, E145, UL-746B, IEC-811, ISO-188,4577.
