Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of quenching devices, in particular to a quenching device for producing memory springs. Background Art
[0002] Memory springs are wound with shape memory alloy wires, utilizing the memory effect of shape memory alloys. They are divided into single - way memory springs and two - way memory springs, and this kind of spring is also a typical structural form of industrial shape memory alloy components. After being stretched, with hot water or hot air as the heat source, the temperature for restoring the original length is 65°C - 85°C, and the original length is made according to customer requirements. The martensite phase of the shape memory alloy (i.e., the phase structure at low temperature, where the low temperature here refers to room temperature) is a soft phase, and the parent phase (i.e., the phase structure at high temperature, where the high temperature here refers to 65°C - 85°C) is a hard phase. Spring production requires quenching treatment of the springs. However, the existing quenching methods will generate a large amount of heat and water vapor, and it is easy to cause harm to the human body if operated carelessly, with many limitations. Therefore, it is necessary to design a quenching device for producing memory springs to solve the problem. Summary of the Invention
