Problems solved by technology

In such an aluminum plating step, impurities such as bubbles or copper oxides often appear at the junction of the two metals of copper and aluminum, which reduces the metallurgical bonding effect of copper and aluminum. The electric corrosion reaction causes the copper material in the copper-aluminum alloy busbar to corrode, which affects the electrical conductivity of the copper-aluminum alloy busbar and reduces its service life

Embodiment Construction

[0010] The following is a further description of a manufacturing process embodiment of a copper-aluminum alloy busbar according to the present invention.

[0011] A copper-aluminum alloy busbar manufacturing process, which includes the steps of pickling, tinning, and aluminum plating of copper plates in sequence. First, the copper plate is immersed in 5% dilute sulfuric acid solution to clean it for 4 to 5 minutes. After drying, in order to prevent the copper from being exposed in the air The generation of oxides or contamination with some grease in the production environment will affect the subsequent processing, so the copper plate should be tinned immediately to ensure product quality. Then take the end of the copper plate coated with a thin tin layer and immerse it in aluminum water and stir the copper plate to form a thin aluminum layer on the end of the copper plate coated with tin. The temperature of the aluminum water is maintained at 670 to 700 ° C, and the stirring ti...

Abstract

The invention discloses a manufacturing process of a copper-aluminum alloy busbar. The key points of the technical scheme include the steps of pickling, tinning, and aluminum plating of the copper plate in sequence. Immerse in aluminum water and stir the copper plate so that the tin-plated end of the copper plate forms a thin aluminum layer, then take the copper plate out of the aluminum water, put the end of the copper plate with the thin aluminum layer into the corresponding mold and pour aluminum water for casting, aiming at Provided is a copper-aluminum alloy busbar manufacturing process which enables the produced copper-aluminum alloy busbar to have better electrical conductivity and higher electric corrosion resistance, and has a simple process.

Description

technical field [0001] The invention relates to a method for manufacturing a busbar, more specifically, it relates to a manufacturing process for a copper-aluminum alloy busbar. Background technique [0002] Busbar, also known as busbar, is often used in power distribution equipment as a conductive material. In order to ensure the electrical conductivity of the busbar on the basis of lower production costs, copper busbars coated with aluminum on one side, that is, copper-aluminum alloy busbars, are usually selected. The existing copper-aluminum alloy busbar manufacturing process usually includes the steps of pickling, tin plating, aluminum plating and other steps of the copper plate. In the aluminum plating step, the copper plate with tin plated at one end is usually directly put into the corresponding mold and aluminum water is added to the corresponding mold. It is cast into shape. In such an aluminum plating step, impurities such as bubbles or copper oxides often appear...
