Problems solved by technology

Most of the rubber high-temperature expansion pressure testing devices in the prior art do not have a control device for rubber expansion when performing a pressure test on rubber, which may cause excessive expansion of the rubber during the pressure test, thereby causing rubber damage. At the same time, the current Advanced Rubber High Temperature Expansion Pressure Test Device When the rubber is expanded, the temperature cannot be controlled to prevent excessive rubber expansion. The above is the problem to be solved by this device.

Abstract

The invention relates to the technical field of rubber, and discloses a rubber thermal expansion performance testing device which comprises a device body and a working cavity arranged in the device body, and a first device plate and a second device plate arranged below the first device plate are fixedly connected between the left wall and the right wall of the working cavity. According to the rubber thermal expansion performance testing device, after rubber is clamped by the device, the rubber is directly heated through a preheating device on a clamping device, the heated rubber expands, and the pressure is digitalized in real time through a pressure spring, so that the thermal expansion coefficient of the rubber changing along with the temperature change can be observed; the device can detect the real-time temperature of the rubber during heating to prevent the rubber from being damaged due to overheating, and meanwhile, a device capable of rapidly cooling the rubber which stops heating is arranged in the device, so that the cooling efficiency is improved; a moving device in the device can adjust the distance of a sensing clamping plate in the pressure detection device so as to adapt to rubber of different sizes.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber thermal expansion performance testing device. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Most of the rubber high-temperature expansion pressure testing devices in the prior art do not have a control device for rubber expansion when performing a pressure test on rubber, which may cause excessive expansion of the rubber during the pressure test, thereby causing rubber damage. At the same time, the current Advanced Rubber High Temperature Expansion Pressure Test Device When the rubber is expanded, the temperature cannot be controlled to prevent excessive rubber expansion. The above is the problem to be solved by this device. Contents of the ...
