Problems solved by technology

However, in the existing copper strip degreasing device, the degreasing agent is an aqueous solution of a "metal cleaning agent". Less than the purpose of complete degreasing
Moreover, the copper strip does not need to be rinsed with clear water after degreasing, and there are traces of dry and solid degreasing agent on the surface, which often makes the surface of the copper strip discolored.

Embodiment 1

[0016] Schematic diagram of the copper strip electrochemical degreasing device figure 1 shown. Among the figure 2 is the degreasing tank formed by plastic welding. Groove size: length 1000mm, width 100mm, height 200mm. Put a certain depth of degreasing agent in the tank.

[0017] There is also an 8V rectified power supply ( figure 1 not shown in ). Its negative pole (-) is in contact with the running copper belt through the roller, and the positive pole (+) is placed in the degreasing tank through the electrode plate.

[0018] Such as figure 2 As shown, the solenoid coil 2 (ie figure 1 10) and the primary stage of the rectified power supply 3 are all connected to the power line of the main motor M of the production line. When the contactor C is connected and the production line is running, the electromagnet coil 2 is energized and the armature is sucked down. From figure 1 It can be seen that now the armature drives the lever 11 to press the transmission case down in...

Abstract

The invention relates to a copper strip electrochemical oil removal method in a clad-welding method copper-clad aluminum wire production line and a device thereof. Specifically, according to the shortcoming that oil stains on the surface of a copper strip in the clad-welding method copper-clad aluminum wire production line can not be thoroughly cleaned, the invention discloses a copper strip electrochemical oil removal agent formula, an oil removal method and a device thereof. A copper strip is processed in a normal-temperature oil removal agent for about 10 seconds, and then the oil stains can be thoroughly removed. The copper strip oil removal device provided by the invention has the structural characteristics that the device is provided with a rectifying power supply; the copper strip is processed for at least 10 seconds in the oil removal agent in the clad-welding production lines at different operation speeds; when the production line stops, the copper strip automatically leaves the oil removal agent; and the copper strip after oil removal is cleaned and dried immediately.

Description

technical field [0001] The invention relates to a copper strip degreasing method on a clad welding copper-clad aluminum wire production line, in particular to an electrochemical degreasing method and a device used therein. Background technique [0002] The current method of producing copper-clad aluminum wire in China is mainly the cladding welding method. Before the copper strip and aluminum rod enter the cladding welding device, the surface needs to be cleaned. Among them, the oil stains on the surface of the copper strip must be removed in the degreasing device to create conditions for the subsequent copper-aluminum metallurgical combination. However, in the existing copper strip degreasing device, the degreasing agent is an aqueous solution of a "metal cleaning agent". Less than the purpose of complete degreasing. Moreover, after the copper strip is degreased, it is not necessary to rinse it with clean water, and there will be traces of dry degreasing agent on the sur...
