Abstract

PURPOSE:To improve the efficiency of the titled machine by interposing a load release mechanism for releasing a load of a test piece at the time of power failure, in a load system for applying the load to the test piece, so that the test piece is not influenced, even if an environment in an atmospheric chamber is varied at the time of power failure. CONSTITUTION:As for a material testing machine, when electric conduction to an electromagnetic brake 6 is cut off at the time of power failure, an operation of the brake 6 is released, and gears 4, 5 do not receive an operation of the brake 6. Therefore, even if pull rods 2H, 2L and a test piece 1 are brought to thermal contraction, no tension load is applied to the test piece 1, and no thermal stress is generated. Accordingly, after the electric conduction, the test can be executed continuously as it is with regard to its test piece 1, and a sufficient test result can be obtained. That is to say, it is unnecessary to execute a re- test newly from the beginning, and the efficiency can be improved.

However, in this type of creep, or in a relaxation tester, when the power to the electric furnace is cut off during a power outage, the Shrink. Conventionally, a tensile load was applied to the test piece due to heat shrinkage of the pull lot and the test piece, resulting in thermal stress. For this reason, even if the test piece is continuously tested after being energized, sufficient test results are often not obtained. Therefore, it was necessary to use a new test piece and conduct the test again from the beginning. In particular, creep or luxation tests take a long time, and retesting from the beginning takes a long time L1.
accompanied by However, the problem was that it was extremely inefficient.

In addition, the same applies when the test piece is housed in an atmosphere chamber in which a low-temperature environment is generated by electricity, and the test piece is subjected to a monthly test in the low-temperature environment. During a power outage, when electricity is turned on or off, the temperature inside the atmospheric chamber rises, causing thermal expansion of the pull lot and test piece.
