Embodiment 1

[0014] A reactor coil lead wire can be manufactured according to the following steps:

[0015] 1) Take a strip-shaped sheet-shaped copper bar for high-temperature annealing treatment. The length of the copper bar is required to be 10cm, the width is 2cm, the thickness is 1.5mm, the annealing temperature is 400°C, and the HB value after annealing is between 45-55;

[0016] 2) Take the aluminum foil with the same shape as the copper bar, the thickness of the aluminum foil is 0.1mm, and the purity is above 99.5%; for the surface treatment of the copper bar and aluminum foil: during the treatment, the single side of the copper bar and the aluminum foil is sanded to remove the oxide layer Treatment to remove the surface oxide layer;

[0017] 3) if figure 1 As shown, the copper bar 4 and the aluminum foil 3 are cold-pressed: within 1 hour after the surface treatment, the mold is used for crimping on the press. The mold is composed of an upper mold 1 and a lower mold 5, wherein the ...

Embodiment 2

[0019] Yet another reactor coil lead wire can be manufactured according to the following steps:

[0020] 1) High-temperature annealing treatment for strip-shaped copper bars: Take a copper bar with a length of 30cm, a width of 5cm, and a thickness of 6mm for annealing treatment. The annealing temperature is 600°C, and the HB value after annealing is between 45-55. between;

[0021] 2) Copper bar and aluminum foil surface treatment: take aluminum foil with the same shape as the copper bar, the thickness of the aluminum foil is 3mm, and the purity is above 99.5%; the copper bar and one side of the aluminum foil are deoxidized and sanded to remove surface oxidation layer;

[0022] 3) Cold crimping of copper bars and aluminum foil: within 1 hour after surface treatment, crimping is carried out on a press using a mold. The mold is composed of an upper mold and a lower mold, wherein the upper mold has several elongated ridge-like protrusions , the ridge-like protrusions are arrang...

Abstract

The invention discloses a manufacturing method of the reactor loop lead wires in the technical field of the reactor, including the following steps: first performing the high temperature anneal process on the strip sheet copper row; then fetching the aluminum foil with the same shape with the copper row, removing the surface oxide layer of the copper row and the aluminum foil; finally performing the cold crimping on the press machine with the copper row and the aluminum foil. The upper die is arranged with a plurality of strip ridge heave arranged in parallel, while the lower die is the rigid flat. The copper row and the aluminum foil are arranged between the upper die and the lower die, wherein the aluminum foil is up and the copper row is down, through the matched molds, the pressure maintaining, the demould, the copper row and the aluminum foil pressed together are fetched, namely the reactor loop lead wires. The method can connect the two materials reliably, with reliable connection and large tensile strength, no electrochemistry rot, no welding, high cleanness, low cost. The obtained product can be used for manufacturing the reactor.

Description

technical field [0001] The invention relates to the manufacturing technology of reactors, in particular to a manufacturing method of reactor coil lead wires. Background technique [0002] In the reactor in the prior art, the coil leads are mainly connected by two materials, one of which is aluminum and the other is copper. At present, there are two manufacturing methods for reactor coil lead wires: 1. Copper-aluminum transition joints are used for connection. The copper-aluminum transition joint itself contains copper and aluminum solder joints. The material of the material is connected, and then the copper electrode and the aluminum electrode are respectively welded to the corresponding copper solder joints and aluminum solder joints. Its production cost is high, and the process is complicated, and it is necessary to solve the copper-to-copper, aluminum-to-aluminum welding process technology. 2. Welding with welding wire: use special welding wire, and use gas welding or e...
