However, the operation process of this method is cumbersome, and the prepared flexible row uses copper as the main material and is easily oxidized in the air. If it needs to be bent for use, the soft connection of the oxidized flexible row at the bend will appear completely bonded. situation, resulting in short circuit and sparking phenomenon, while increasing superimposed resistance, resulting in high temperature, affecting the safe use of related components, and the shock resistance of soft row components is limited

[0012] The embodiment of the present invention provides a kind of preparation method of soft aluminum row, it comprises:

[0013] First, the aluminum foil is divided into aluminum sheets, and then the multi-layer aluminum sheets are processed and connected into a soft aluminum row, and then the two ends of the soft aluminum row are welded at 400-600°C and 1-5 atmospheres for 10-50s Form the hard-state connecting section, that is, make the soft aluminum row; the two ends of the soft aluminum row are fusion-press welded by the method of polymer diffusion welding and / or argon arc welding, and the two ends of the made soft aluminum row end directly with the battery arrangement.

[0014] More preferably, the soft aluminum row is formed by connecting 25 layers of aluminum sheets.

[0015] More preferably, the thickness of the aluminum sheet is 0.1-0.5mm.

[0016] More preferably, the aluminum foil is connected with a Vickers hardness of AL1060O state less than 25 degrees.

Embodiment 1

[0027] Preparation of soft aluminum row: provide an aluminum foil with AL1060O state Vickers hardness less than 25 degrees, divide the aluminum foil into aluminum sheets, then weld 25 layers of 0.1mm aluminum foil to form a soft row, and then put the two ends of the soft row at 520°C 1. Polymer diffusion welding treatment under 3 atmospheric pressure conditions for 15s, that is, the soft aluminum row is produced.

Embodiment 2

[0029] Preparation of soft aluminum row: Provide an aluminum foil with AL1060O state Vickers hardness less than 25 degrees, divide the aluminum foil into aluminum sheets, then weld 30 layers of 0.1mm aluminum foil to form a soft row, and then put the two ends of the soft row at 520°C 1. Under the condition of 3 atmospheric pressure, the argon arc welding process was performed for 15s, and the soft aluminum row was obtained.

Abstract

The invention provides a manufacturing method and an application of a soft aluminum bar. The method comprises the following steps: shredding an aluminum foil into aluminum sheets; treating the plurality of layers of aluminum sheets and connecting the treated aluminum sheets into a soft aluminum bar; and melting, pressing and welding two ends of the soft aluminum bar at a temperature being 400-600 DEG C and under 1-5 atmospheric pressures for 10-50 seconds to form a hard-state connection segment in order to obtain the soft aluminum bar. The two ends of the soft aluminum bar are molten, pressed and welded by high-polymer dispersion welding and / or argon arc welding, and the two ends of the manufactured soft aluminum bar are directly arranged together with a battery. The soft aluminum bar is made of aluminum, light in weight, and made by a melting, pressing and welding method. Moreover, the soft aluminum bar is directly arranged by spot welding, so that the arrangement defects in a conventional screw fixing method are overcome; time and cost are saved; the overall cruising time is prolonged; and the defects of easiness in heating, high energy consumption and the like in a use process of a conventional bus are overcome. The soft aluminum bar has the advantages of saving in energy, lowering in energy consumption, superior conductivity, long service life, freeness from maintenance, attractive appearance and the like.

Description

technical field [0001] The invention relates to a method for preparing soft aluminum bars, belonging to the field of bus bars. Background technique [0002] In the prior art, the soft row assembly is made of multiple copper sheets stacked together, and the two ends are welded and fixed with screws for arrangement, and the middle is connected with soft copper and then electroplated. However, the operation process of this method is cumbersome, and the prepared flexible row uses copper as the main material and is easily oxidized in the air. If it needs to be bent for use, the soft connection of the oxidized flexible row at the bend will appear completely bonded. In case of accidents, it will lead to short circuit and sparking phenomenon, and at the same time increase the superimposed resistance, generate high temperature, affect the safe use of related components, and the anti-seismic ability of soft row components is limited. [0003] Therefore, it is an urgent problem to dev...
