Cold and heat fatigue test device and method

Abstract

The invention discloses a cold and heat fatigue test device and method. The cold and heat fatigue test device comprises a machine case, a first water tank, a second water tank, a sample basket, a first driving device, a workpiece inflating pipeline and an airtightness detection element, wherein the machine case comprises a base; the first water tank and the second water tank are arranged on the base; the water temperature in the first water tank is different from the water temperature in the second water tank; the sample basket is used for accommodating a workpiece; the sample basket is arranged above the base; the first driving device comprises a horizontal driving mechanism and a vertical driving mechanism; the horizontal driving mechanism is used for driving the sample basket to do reciprocating movement in a position between the upper sides of the first water tank and the second water tank; the vertical driving mechanism is used for driving the sample basket to do ascending and descending movement; the workpiece inflating pipeline is used for performing ventilation on the workpiece; the airtightness detection element is used for performing airtightness detection on the workpiece during the workpiece ventilation. The device and the method can be used for automatically testing the fatigue of the workpiece and have the advantages that the test efficiency is high, and the manual operation can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of workpiece testing, in particular to a thermal fatigue testing device and method. Background technique [0002] At present, the pipe fittings, valves and other workpieces used in the pipeline system will be used in the environment of alternating hot water and cold water. Such an environment will have a great impact on the rubber parts and metal parts in the workpiece. Aging and stress, prone to fatigue problems such as water leakage and cracking. However, the traditional workpiece fatigue testing is manual operation, the operation intensity is high, and the test efficiency is low. Contents of the invention [0003] Based on this, the embodiment of the present invention overcomes the defects of the prior art, and provides a thermal fatigue testing device and method, which can automatically test the fatigue of workpieces, have high testing efficiency, and can effectively reduce manual operations.
