AI Technical Summary

Problems solved by technology

Due to the large thermal conductivity of metal materials, the metal connecting arm will heat or cool the force sensor of the universal testing machine, which will make the measurement of force load inaccurate
For the hydraulic universal testing machine, the heat conduction between the connecting arm and the metal piston may also cause part of the hydraulic oil of the universal testing machine to be overheated or overcooled, causing the failure of the testing machine

Abstract

The invention discloses a heat insulation apparatus capable of transmitting tension and pressure. The apparatus comprises an upper connecting arm and a lower connecting arm, and the upper connecting arm is connected with the lower connecting arm through engineering plastic with the yield strength being greater than 20MPa in order to reduce heat conduction between the upper connecting arm and the lower connecting arm. The apparatus can transmit large tension and pressure load, can effectively reduce influences of high temperature or low temperature environment in an incubator on a universal testing machine to make the force sensor of the universal testing machine and the temperature of hydraulic oil stabilize in a normal working stabilization range, and well solves the problem of poor heat insulation of mechanically loaded heat insulation apparatus only having a good tension transmission performance of present testing machines.

Description

technical field [0001] The invention belongs to a heat insulation device, in particular to a heat insulation device capable of transmitting tension and pressure. Background technique [0002] Many mechanical parts need to work in high or low temperature environments, such as satellite parts, aviation or aerospace engine blades, etc. Therefore, testing the mechanical properties of engineering materials such as metals and plastics at high and low temperatures is one of the key steps in material selection for mechanical parts. [0003] At present, most engineering materials such as metals and plastics are tested for mechanical properties at high temperature and low temperature by applying force loads to the test specimens in a temperature-controlled temperature box, such as figure 1 shown. When a large load is applied, the figure 1 The connecting arm is usually made of metal (such as 45# steel) material. Due to the large thermal conductivity of metal materials, the metal co...
