preparation example Construction

[0026] As introduced in the background technology, the shell of the current car (including the hood, the door, the tailgate, etc.) is molded from sheet metal. After the vehicle is rear-ended or collided, it will be deformed and cannot be automatically reshaped. . Therefore, the present invention proposes a kind of preparation method of the copper alloy smart car shell that can automatically reshape, comprising the following steps:

[0027] The first step is to use copper alloy plates to replace the plates used in the current shell;

[0028] The second step is to use the copper alloy plate to process the shell according to the current equipment tooling process;

[0029] The third step is to put the shell processed in the second step into the heating equipment, heat it to 840°C-845°C, and keep it warm for 15-19 minutes;

[0030] The fourth step is to take out the shell that has been heated and kept warm in the third step, put it into boiling water, and keep it for 35-40 minute...

Embodiment 1

[0037] Embodiment 1: a kind of preparation method of the copper alloy smart car shell that can automatically reshape, comprises the following steps:

[0038] The first step is to put the cylindrical copper alloy mesh into the heating equipment, heat it to 840°C, and keep it warm for 15 minutes;

[0039] The second step is to take out the shell that has been heated and kept warm in the second step, put it in boiling water, and keep it for 35 minutes;

[0040] Step 3 Remove the shell from the boiling water and place it in liquid nitrogen to cool for 5 minutes.

[0041] The fourth step is polishing or coloring.

[0042] The phase transition point As of the copper alloy in the first step is ≤-41°C.

[0043] Performance test: the cylindrical copper alloy net prepared in embodiment 1 (such as figure 1 ), hold it with tweezers for 2~3s until it is completely deformed (such as figure 2 ), release the tweezers, and the cylindrical copper alloy mesh quickly (1~2s) returns to its or...

Embodiment 2

[0044] Embodiment 2: a kind of preparation method of the copper alloy smart car shell that can automatically reshape, comprises the following steps:

[0045] The first step is to use copper alloy plates to replace the plates used in the current shell;

[0046] The second step is to use the copper alloy plate to process the shell according to the current equipment tooling process;

[0047] The third step is to put the shell processed in the second step into the heating equipment, heat it to 845°C, and keep it warm for 19 minutes;

[0048] The fourth step is to take out the shell that has been heated and kept warm in the third step, put it in boiling water, and keep it for 40 minutes;

[0049] Step 5 Remove the shell from the boiling water and cool in liquid nitrogen for 10 minutes.

[0050] The sixth step is polishing or coloring.

[0051] The phase transition point As of the copper alloy in the first step is ≤-42°C.

Abstract

The invention relates to a preparation method of a copper alloy intelligent car shell capable of being automatically reshaped. The preparation method comprises the following steps that firstly, a copper alloy plate is used for replacing a plate used for an existing shell; secondly, a copper alloy plate is used for machining and forming the shell according to an existing equipment tool technology;thirdly, the shell machined in the second step is put into heating equipment, and heating and heat preservation are conducted for a certain period of time; fourthly, the shell is put into liquid to becooled for a certain period of time; fifthly, polishing or coloring is performed. The preparation process is simple, can be applied on the basis of original tooling equipment, and is economical and low in cost. When 5G comes, an intelligent maintenance function is added for the driving of the intelligent car, so that the maintenance cost is reduced, the operation time is prolonged, and the intelligent car is more intelligent. Therefore, the method has high development and application value for practical application.

Description

technical field [0001] The invention belongs to a method for preparing an intelligent car shell, in particular to a method for preparing a copper alloy intelligent car shell that can be automatically replicated. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] The shell of the car (including the hood, the door, the tailgate, etc.) that people use now is molded from sheet metal, but after the vehicle is rear-ended or collided, it will be deformed, and the deformed vehicle can only be sent to For 4S shop maintenance, it takes 1 to several days to pick up the car. Not only lost time, but also time-consuming. Contents of the invention [0004] In order to overcome the shor...
