Background technology
Mostly the needing of rubber item has good heat-resisting and ageing-resistant performance, to improve the stability of rubber item. Such as: as the rubber item of a kind of industrial widespread use, rubber conveyer belt is usually used to the conveying of the high-temperature materials such as cement, coke, ore, the ability of its high temperature heat-resistant oxygen aging under operation there is high requirements.
Accurate testing rubber pressure-and heat-resistance performance in actual use has important meaning for Design and manufacture elastomeric material. Traditionally, the testing method of rubber heat aging property is after rubber item is placed certain time in oven heat, test mechanics performance variation. But, this kind of testing method can only simulate the temperature under isoperibol to the impact of rubber. Under most of environment for use, there is thermograde in the heating status of elastomeric material, namely there is temperature head between the upper and lower surface of rubber item or interior outside surface. Such as, when using as rubber conveyer belt, elastomeric material is in the environment that one side is heated, and rubber two sides exists temperature head; When using as tire, owing to frictional force difference exists temperature head between tyre contact patch and side. Testing state in such true heating status and ageing oven inconsistent, therefore traditional detection method cannot be used for the pressure-and heat-resistance performance of testing rubber goods under non-constant temperature working conditions.
Summary of the invention
For the deficiencies in the prior art, the present invention discloses a kind of new testing apparatus, can be used for the temperature gradient conditions that rubber item under Reality simulation applied environment faces, thus provides the heat-resistant pressure-resistant performance of rubber item more accurately.
The present invention is specific implementation by following technical solution:
The heat-resistant pressure-resistant performance test apparatus of a kind of rubber item, comprise the skeleton construction being made up of lower bottom seat, upper end support, both sides column, the first platform and the 2nd platform of arranged opposite it is provided with in skeleton construction, first platform is connected to upper end support by union lever, and the 2nd platform is connected to lower bottom seat by lifting bar; It is provided with grip unit, for fixed placement rubber item to be measured, it is possible to provide goods to be measured a tensile stress effect according to actual needs between the first platform and the 2nd platform; First platform, the 2nd platform are equipped with constant temperature unit, for generation of rubber item heating status to be measured.
By said structure, being positioned over by rubber item to be measured between first platform and the 2nd platform, the distance adjusted between two platforms makes the two fit; Adjust the constant temperature unit in the first platform, the 2nd platform respectively, two surfaces of rubber item are made to reach temperature required state, maintain temperature required state to terminate to the test duration, the follow-up test that the carrying out that sample after having tested is further is comprised mechanical property etc., thus detect the resistance toheat of rubber item; By adjusting lifting bar, the pressure suffered by adjustable rubber item, by adjustment grip unit, the tension force suffered by adjustable rubber item.
In order to the convenience used, it is preferable that, the first platform is positioned at top, is connected to upper end support by union lever; 2nd platform is positioned at lower section, is connected to lower bottom seat by lifting bar.
In the present invention, constant temperature unit can adopt various thermostat to realize, by the temperature of constant temperature unit adjusted in two platforms, it may be achieved the temperature head adjustment between rubber item two surfaces. Preferably, constant temperature unit adopts electrically driven (operated) well heater and water-cooled module, and the control unit of the two is connected to temperature regulator.
Adopt said apparatus, the adjustment to heater power, the water yield of water-cooled module and flow velocity adjustment can be utilized, it is achieved the accuracy controlling of temperature, simulate continuous print temperature variation better, it is possible to be the thermally equivalent face under rubber item provides all temps state.
For the ease of understanding the mechanical property of rubber item, described grip unit is stretcher, and for providing tensile stress for rubber item to be measured, the sidewall of column is fixed at the two ends of stretcher.
In the present invention, the size of each assembly, specification etc. not be particularly restricted, it is contemplated that to conventional testing circumstance, the specification of the first platform and the 2nd platform is length of side 100-500mm, thickness 5-15mm; The diameter of lifting bar is 50-150mm, is highly 200-600mm.
In the present invention, the type of each assembly can adjust according to actual needs, and usual first platform, the 2nd platform can adopt cast iron surface plate, stainless steel flat plate, copper flat board or earthenware slab, as long as it has the needs that good heat conductivility can meet the present invention.
In the present invention, lifting bar, stretcher all can adopt this base part common. Such as, lifting bar can be hydraulic pressure, pneumatic or mechanical power, and stretcher can be spring stretching, mechanical stretching or pneumatic stretching.
In the present invention, rubber testing batten can be long strip shape or square, and concrete shape is determined according to the type of stretcher, and thickness is 2-20mm. Test bars size should slightly larger than platform size (long strip shape batten length be slightly larger than platform size), and concrete size is determined according to platform size.
In the present invention, the rubber sample after test as need further cutting size to carry out follow-up test, the cutting region that should select for being close to platform, distance platform edges 10-20mm middle heat affected zone.
