Copper strip surface degreasing device

Abstract

The invention discloses a copper strip surface degreasing device, which comprises a container containing cleaning agent. The container and a frictional cleaning device are fixed in a box body. The container is provided with a conveying device conveying the cleaning agent to the frictional cleaning device. The frictional cleaning device comprises an upper friction body and a lower friction body, between which a gap is left for the end part of a copper strip to insert. The invention can clean the greasy dirt accumulating on the surface of the copper strip thoroughly and has the advantages of clean cleaning and high efficiency.

Description

technical field [0001] The invention relates to a copper strip degreasing device in a copper-clad aluminum production line, in particular to a copper strip surface degreasing device. Background technique [0002] For the production of copper-clad aluminum wire, a layer of copper strip is coated on the surface of the aluminum rod. In the production of known copper-clad aluminum wires at present, the surface of the copper strip must be degreased before cladding and welding, and this process is an indispensable process link. At present, all manufacturers of copper-clad aluminum wires use the same process to degrease the surface of copper strips before cladding welding. And install the copper belt guide wheel in the container, one of the guide wheels is immersed in the cleaning agent, due to the pressure of the guide wheel, the copper belt is in contact with the metal cleaning agent during operation, and the excess metal cleaning agent is scraped off by the wiper . The latter...

Problems solved by technology

The latter degreasing method has the same technological structure, except that the copper strip degreasing device is removed from the pretreatment machine. The problem in the two forms is that when the copper strip is running, under the action of the guide wheel, the copper strip is immersed in the area of ​​the cleaning agent. Limited, no residence time, the oil film on the copper strip is relatively firm on the surface of the copper strip, especially when the oil film is thick, it is difficult to completely remove it with this process. If the oil film is not completely removed, the copper strip will run The surface of the copper strip after scrubbing is re-coated with a layer of oil film. After cladding and welding, the metallurgical bonding between copper and aluminum will be seriously affected. Due to the existence of the oil film on the bonding layer, the wire diameter needs to be deformed if it is small. Combined, it can be seen that the degreasing process before the coating production line is very important. It is related to whether the subsequent processes can be carried out smoothly, and directly affects the production cost and yield
