Embodiment 1

[0020] Embodiment 1: A kind of preparation method that does not need the automatic paddling blade of power drive, comprises the following steps:

[0021] The first step is to determine that the chemical composition of the TiNi alloy is Ti 44.95wt%, and the rest is Ni;

[0022] The second step is to cold roll the TiNi alloy into strips;

[0023] The third step is to cut the cold-rolled strip into strips with a length of 10 cm and a width of 2 cm to form TiNi alloy strips;

[0024] The fourth step is to put the TiNi alloy strip cut out in the third step into the heating furnace flatly, and heat it to 798 ° C for 118 minutes;

[0025] After the fifth step of heat preservation is completed, the TiNi alloy strip is taken out of the heating furnace and cooled to room temperature;

[0026] The sixth step is to determine the inner diameter of the restrained copper pipe according to the formula R=h(1+ε) / 2ε. In the formula, R represents the inner diameter of the restrained copper pipe...

Abstract

The invention relates to a manufacturing method of an automatic paddle blade dispensing with power drive, comprising the following steps: 1) determining chemical composition of TiNi alloy; 2) cold-rolling the TiNi alloy to strips; 3) cutting the cold-rolled strip into TiNi alloy strips; 4) heating the cut TiNi alloy strips in a heating furnace and preserving heat; 5) after heat preservation, taking the TiNi alloy strips out of the heating furnace and water-cooling the TiNi alloy strips to the room temperature; 6) determining internal sizes of constraint copper pipes or aluminum pipes; 7) rolling the water-cooled TiNi alloy strips into cylinders and loading the cylinders into the constraint copper pipes or aluminum pipes; 8) heating the TiNi alloy strips in the constraint copper pipes or aluminum pipes in the heating furnace and preserving the heat; 9) after coming up to the holding time, taking the TiNi alloy strips in the constraint copper pipes or aluminum pipes out and cooling the TiNi alloy strips to the room temperature. Compared with the manufacturing processes of internal-combustion engines, the manufacturing processes of the method are simple; the manufacturing price is low; the TiNi alloy blades manufactured by the method can be used for all the motor vessels.

Description

technical field [0001] The invention relates to a method for preparing a water paddle, in particular to a method for preparing an automatic water paddle without power drive. Background technique [0002] At present, all mechanically powered boats and ships in the sea, the Yangtze River, the Yellow River and inland river basins need to be driven by internal combustion engines, and the number of them can be imagined. The fuel used by the internal combustion engine belongs to non-renewable energy, and the non-renewable energy is very scarce at present, and the preparation process of the internal combustion engine is complicated and the cost is high. In the case of increasing shortage of non-renewable energy sources, it is urgent to develop a paddle preparation process that no longer uses non-renewable energy sources, but only uses the temperature difference between water and air to make paddles automatically paddle. Contents of the invention [0003] The purpose of the prese...
