Embodiment 1

[0021] A preparation method for an intelligent driver chip of an over-temperature early warning device, comprising the following steps:

[0022] In the first step, the NiTi alloy plate is made into a strip, the Ni content of the NiTi alloy is above 50.5 at%, and the alloy strip has a width of 6 mm and a length of 60 mm;

[0023] In the second step, put the long strip made in the first step in the furnace at 800°C for 1.5 hours, then take it out and cool it; place the long strip straight in the furnace without bending; put it in cold water to cool;

[0024] The third step is to fix the strips cooled in the second step. The fixing means bending the strips cooled in the second step into a semicircle and placing them in copper tubes with equal inner diameters. The inner diameter of the copper tube depends on the assembly distance;

[0025] The fourth step is to put the driver piece fixed in the third step into the furnace and heat it at 400°C for 24 hours, then take it out and co...

Embodiment 2

[0028] A preparation method for an intelligent driver chip of an over-temperature early warning device, comprising the following steps:

[0029] In the first step, the NiTi alloy plate is made into a strip, the Ni content of the NiTi alloy is above 50.5 at%, and the alloy strip has a width of 8 mm and a length of 70 mm;

[0030] In the second step, put the long strip made in the first step in the furnace at 820°C for 1.75 hours, then take it out and cool it; place the long strip straight in the furnace without bending; put it in cold water to cool;

[0031] The third step is to fix the strips cooled in the second step. The fixing means bending the strips cooled in the second step into a semicircle and placing them in copper tubes with equal inner diameters. The inner diameter of the copper tube depends on the assembly distance;

[0032] The fourth step is to put the driver piece fixed in the third step into the furnace and heat it at 450°C for 48 hours, then take it out and c...

Embodiment 3

[0035] A preparation method for an intelligent driver chip of an over-temperature early warning device, comprising the following steps:

[0036] In the first step, the NiTi alloy plate is made into a strip, the Ni content of the NiTi alloy is above 50.5 at%, and the alloy strip is 10 mm wide and 100 mm long;

[0037] In the second step, put the long strip made in the first step in the furnace at 850°C for 2 hours, then take it out and cool it; place the long strip straight in the furnace without bending; put it in cold water to cool;

[0038] The third step is to fix the strips cooled in the second step. The fixing means bending the strips cooled in the second step into a semicircle and placing them in copper tubes with equal inner diameters. The inner diameter of the copper tube depends on the assembly distance;

[0039] The fourth step is to put the driver piece fixed in the third step into the furnace and heat it at 500°C for 72 hours, then take it out and cool it;

Abstract

The invention discloses a method for preparing an intelligent driving chip of an over-temperature early warning device, which comprises the following steps: the first step is to make an alloy plate into a long strip; the second step is to place the long strip made in the first step in a furnace for heating and heat preservation time. Then, take it out and cool it; the third step is to fix the strips cooled in the second step; the fourth step is to put the drive plate fixed in the third step into the furnace for heating and heat preservation. Then, take it out and cool it; the fifth step is to deform the driving piece after cooling in the fourth step. After that it can be applied. The preparation method of the invention is simple, the cost is low, and the installation and use are convenient. When installing and using, you only need to install the smart driving piece under the power contact, and the opening of the smart alloy driving piece is facing downward. In this way, when the temperature is overheated or overheated, an alarm can be issued; when the temperature returns to normal, the alarm stops. Therefore, the present invention has high development and application value for practical application.

Description

technical field [0001] The invention belongs to the field of preparation of an intelligent driving chip, and in particular relates to a method for preparing an intelligent driving chip of an over-temperature early warning device. Background technique [0002] Alarms are required in case of fire, early warnings are required for equipment overheating, early warnings are required for overheating in greenhouses, and overtemperatures in important storage areas such as oil depots require early warnings. Otherwise, the consequences will be disastrous. Regardless of whether it is an alarm device or an early warning device, the key core components of the alarm or early warning must have both the function of temperature detection and the function of executing the drive. In addition, it should also have the characteristics of saving raw materials, low production cost, and long life. Existing similar devices do not possess these excellent functions and characteristics. Contents of t...
