Description
Technical Field
The utility model relates to a testing tool technical field specifically is a test rubber elastomer compression permanent deformation's instrument.
Background
The test method for compression set is described in detail in the standard ASTM D395. The instrument used corresponding to the test method needs to be put into the device when being used, and the sample must be placed in the middle of the pressure plate to prevent inclination. The screw was tightened using the calibrated spring device until the deformation data read on the scale was the same as the corresponding 1.8kN force spring deformation on the calibration curve.
The disadvantages of such a test device are: 1. the sample needs to be placed in the middle of the pressure plate, whether the side is easy to incline, the error ratio is large, 2, the sample testing process is troublesome, and a spring calibration curve needs to be compared when the screw is screwed down. 3. Since the device is sometimes used under high temperature and high humidity conditions, the spring constant of the spring is easily changed after a long-term use, and thus, a test error is easily generated. The need to compensate for this possible error requires periodic calibration of the spring and the replacement of the spring which has changed in time. 4. The whole device is taken as a whole, the disassembly difficulty is large, and the carrying or moving is inconvenient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a test rubber elastomer compression permanent set's instrument to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a test rubber elastomer compression permanent deformation's instrument, includes the last platform of pressing, puts thing platform, screw rod one end with put the thing platform and connect, the screw rod penetrates the through-hole on the last platform of pressing, it has the nut still to go back threaded connection on the screw rod, the screw rod is threaded connection with the connected mode who puts the thing platform, the nut is used for carrying on spacingly to the last platform of pressing, the nut adopts the goat's horn nut, it is provided with and is used for carrying on spacing piece to the sample that awaits measuring to put the thing bench, it adopts stainless steel to press the platform, put thing platform, nut, screw rod, spacing piece adopts titanium alloy material.
Preferably, the number of the screws is three.
Preferably, the upper pressing table and the object placing table are both cylindrical.
Compared with the prior art, the beneficial effects of the utility model are that:
1. in the utility model, the sample is only required to be placed in a triangular area formed by three screws, and the limit pieces are placed on the periphery of the test sample, so that the test sample is slightly off the center without test error;
2. the utility model discloses, go up and press the platform and put the thing platform and adopt 201 stainless steel, corrosion-resistant, the deformation diminishes. The limiting block is made of titanium alloy, is corrosion-resistant, has small size error, is hard and not easy to change, has no test error caused by the material of the equipment after long-term use, and does not need to be calibrated frequently;
3. the utility model uses the claw nut to fix and pressurize, does not need to use a spanner, can be screwed up and pressurized manually, ensures that the upper pressure table compresses the limiting sheet, ensures that the test sample is compressed under the specified pressure and size;
4. the utility model discloses, equipment disassembly is simple, convenient to carry.
