Description
Technical field
The present invention relates to the copper strips deoiling method on tube-weld cladding technique copper-clad aluminum conductor production line, especially a kind of electrochemistry is removed
Oily method and its device used.
Background technology
The method of the domestic copper-clad aluminum conductor of production at present is mainly tube-weld cladding technique.Copper strips is entering clad welded dress with aluminium bar
Before putting, its surface Jin Hang Cheongju need to be managed.Wherein copper strips must remove the oil stain on surface in degreasing unit Zhong Cheongju, be subsequent copper aluminium smelting
Gold is combined and created conditions.But in used copper strip deoiling device, degreaser is a kind of aqueous solution of " metal cleaner ", copper strips
The duration of runs in this degreaser is very short, therefore deoiling effect is little, does not reach the purpose of thorough oil removing at all.And copper
Bu Yong Cheongju water rinses after band oil removing, and surface remaining has solid degreaser trace, often copper strip surface is changed colour.
The content of the invention
The purpose of the present invention is for deficiency of the existing copper with deoiling method and its equipment therefor, there is provided one kind can ensure thorough
Bottom Cheongju removes the electrochemical regimes of oil stain, while provides the device suitable for this deoiling method.
A kind of degreaser that copper strip surface oil stain is removed for tube-weld cladding technique copper-clad aluminum conductor, by following component by certain ratio
Example allotment forms：Sodium hydroxide, sodium carbonate, sodium phosphate and sodium metasilicate, the solution ph being configured to are 13~14.
In the present invention, the formula of degreaser is：Sodium hydroxide 20g/L, sodium carbonate 20g/L, sodium phosphate 50g/L and sodium metasilicate
10g/L。
In the present invention, use when, need to carry out electrochemical degreasing at normal temperatures.
In the present invention, use when, uses 8V rectifier power sources, and copper strips connects (-) pole, and degreaser connects (+) pole.
In the present invention, the oil removing time is at least 10s.
In the present invention, the structure of used copper strip deoiling device should meet following requirements during oil removing：With rectifier power source；
The clad welded production line of the different speeds of service should all make copper strips at least run 10s in degreaser；During production line stop, copper strips
Automatically degreaser is left；Clean and dry up immediately after copper strips oil removing.
The present invention uses alkaline degreaser.For example, sodium hydroxide 20g/L, sodium carbonate 20g/L, sodium phosphate 50g/L and silicic acid
The solution that sodium 10g/L is made into, pH value are 13~14.Using 8V rectifier power sources, copper strips connects (-), and degreaser connects (+).After oil removing
Copper strips cleaned in clear water after, the water on surface is not collected as droplet, but uniformly spreads out wetting, and showing to deoil works well.
Since strong basicity degreaser has oxidation to copper strip surface, if copper strips storage period in this degreaser
It is long, surface oxidation will be made to change colour.
Degreasing tank that degreasing unit is welded into by one with low carbon steel plate, being placed with degreaser, places one with modeling in groove
Copper strips carrying case made of material, is equipped with multiple rollers in case, to transmit copper strips.The bottom plate of this case is provided with compared with multiple hole, and the bottom of at
Four corners of plate are erected in degreasing tank by spring.The side plate of carrying case is connected with electromagnet armature and lever.Pass through
The synergy of spring and electromagnet, can be such that transmission case body is moved up and down in degreasing tank.When turn-on current in electromagnet coil
When, armature drives lever to move down, and makes the spring-compressed of copper strips carrying case bottom and enters in degreasing tank and carry out oil removing.Work as electricity
After magnet coil power-off, under the action of bottom spring, copper strips carrying case item is risen, copper strips is left degreaser.In order to improve
Deoiling effect, quickening remove speed oil, the rectifier power source of 8V are equipped with degreasing tank, to carry out electrochemical degreasing.After oil removing
Copper strips, which enters in Rinsing Area, to be cleaned, and is dried up immediately with hair drier after washing.
Brief description of the drawings
Attached drawing 1 is copper strips electrochemical degreasing apparatus structure schematic diagram.
Attached drawing 2 is copper strips electrochemical degreasing device electrical schematic.
Embodiment
Embodiment 1.
Copper strips electrochemical degreasing apparatus structure schematic diagram is as shown in Figure 1.2 degreasing tank to be welded with plastics in figure.
The size of groove：Long 1000mm, Wide 100mm, high 200mm.The degreaser of certain depth is put into groove.
8V rectifier power sources (not shown in Fig. 1) are additionally provided with the present apparatus.Its anode (-) passes through roller and the copper of operation
Band contact, cathode (+) are placed in degreasing tank by electrode plate.
As shown in Fig. 2, the primary of electromagnet coil 2 (i.e. 10 in Fig. 1) and rectifier power source 3 is all connected on production line main motor
On the power cord of M.When contactor C connections, production line, it is powered in electromagnet coil 2, inhales lower armature.It can be seen from figure 1 that
Armature drives lever 11 that transmission case is depressed into degreasing tank (spring 5 is compressed) at this time, makes copper strips in degreaser to reach
It is dynamic.At the same time, the primary of rectifier power source is also connected, and produces 8V DC voltages, copper strips is carried out electrochemical degreasing.Work as contactor
When C is disconnected, main motor M stallings, make production line stop movement.At the same time, electromagnet coil powers off, and loses and armature is drawn
Power, makes copper strips carrying case rely on the elastic force effect of spring 5 in Fig. 1 and move up, departs from degreaser.At this time, the primary of rectifier power source
Also power off at the same time, without the function of electrochemical degreasing.
Copper strips after oil removing includes the degreaser of surface remaining through including hydrophone 6, into sink 7.Copper strips is through the clear of flowing
After water rinses, the moisture content of surface remaining is included through including hydrophone 8, is then dried up surface by high-power hair drier 9.
The speed of service for the copper-clad aluminum conductor clad welded production line that the country makes has two kinds at present.One kind is traditional clad welded
Production line, speed of service 7.5m/min, another kind are intelligent clad welded production lines, speed of service 15m/min.In order to
Ensure that copper strips must run 10s in degreaser, can calculate for former production line, operation of the copper strips in degreaser
Length is 1250mm.The just length between each roller designed in Fig. 1 shown by distance.For intelligent clad welded
Production line, since the speed of service is very fast, can be installed to location of C, then between each roller shown by distance by the roller B in Fig. 1
Copper strips length is 2500mm, meets the requirement that the production line speed of service is 15m/min.
The present invention is described by embodiment, and those skilled in the art know, is not departing from the spirit of the present invention
In the case of scope, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in the finger of the present invention
Lead down, can modify to these features and embodiment to adapt to the essence of particular situation and material without departing from the present invention
God and scope.Therefore, the present invention is not limited to the particular embodiment disclosed, and falls with claims hereof
In the range of embodiment belong to protection scope of the present invention.
