Description
Technical field
The present invention relates to copper foil manufacturing field, is related to inside the key component cathode roll in copper foil manufacturing production equipment
Conductive structure.
Background technology
Important source material of the copper foil as electronic device, has been deep into industry-by-industry, the important tool produced as copper foil,
Cathode roll is constantly subjected to the attention and protection of every country, and China only has two to three manufacturing enterprises for having independent intellectual property right,
Its is complicated, and process is various, production capacity is required high.In the production process of copper foil, electrochemical reaction is primarily involved in
Be exactly anode slot and cathode roll, be reduced and adsorbed by electrochemical reaction copper ion and form copper foil in cathode roller surface,
Electric current flows through anode slot and cathode roll during this, to produce the qualified copper foil that thickness is uniform, compactness extent is identical, cathode roll
One of the main influence factor of conductive structure.
The distribution of the rational design of cathode roll conductive structure directly decision cathode roll roll surface power line, in per unit area
The density of electric fluxline is identical, identical intensity is the optimal state of cathode roller surface power line.In order to reach or infinite approach this
State, rational conductive structure are vital.
The content of the invention
It is an object of the invention to provide a kind of cathode roll inner conductive knot of roll surface power line infinite approach equiblibrium mass distribution
Structure.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：Including steel shaft and be sleeved in steel shaft two
Fagging, two support plates it is cylindrical on be respectively installed with the steel core that is made of layers of copper and steel cylinder, the steel shaft on the outside of two support plates
On be respectively installed with conductive copper sheathing and the copper coin identical with steel core diameter from inside to outside, copper coin covering support plate and steel
Core, copper dish are equipped with conductive copper sheathing overcoat, and titanium cylinder is housed in steel core and copper coin outer sheath.
The layers of copper and steel cylinder use the steel core of Explosion composite.
Elastic conjunction conduction copper sheathing in the steel shaft.
The copper dish are welded on copper coin.
The titanium cylinder elastic conjunction is on the outside of steel core and copper coin.
The steel core outer wall and titanium cylinder inner wall has silvering.
The advantage of the invention is that allowing high current, low-heat power consumption, cathode roll roll surface power line is uniform, and cost is relatively low,
The outside diameter of the interior boring ratio copper dish of copper coin is 1 to 2 millimeter big in old structure, and the thickness of copper dish is 23 millimeters, and copper dish are by the mode welded
It is embedded in and is fixed on copper coin and be centrally formed conductive layer, for new construction is compared to old structure, copper coin endoporus is small, the milli of copper dish thickness 15
Rice, the effect of cost is reduced to reduce raw material usage, reduce processing capacity and reach；In old structure, electric current by copper sheathing, copper dish,
Copper coin finally flows through roll surface, and every kind of part will be fixed with welding and conducting electric current, and electric current will get to roller by 3 weld seams
Face, and electric current is divided into two-way in new construction, the first via are directly communicated to roll surface by conductive copper sheathing, copper coin, secondary route conduction copper sheathing,
Copper dish and copper coin lead to roll surface again, are welded in the lump with copper sheathing conduction copper sheathing after copper dish and copper coin are superimposed in new construction, real
Now three parts are stitched together by overall weld seam together, the shunting that electric current can be full and uniform, improve current capacity, subtract
Few local high current release heat.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
Invention is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the present invention includes steel shaft 1-8 and two support plate 1-4 being sleeved on steel shaft 1-8, in two support plates
1-4 it is cylindrical on be set with the steel core that forms of Explosion composite used by layers of copper 1-2 and steel cylinder 1-3, on the outside of two support plate 1-4
Steel shaft 1-8 on be respectively installed with conductive copper sheathing 1-7 and the copper coin 1-5 identical with steel core diameter, the copper coin from inside to outside
1-5 covers support plate and steel core, is set with copper dish 1-6 outside conductive copper sheathing 1-7, the elastic conjunction on the outside of steel core and copper coin 1-5
There is titanium cylinder 1-1.Wherein conductive copper sheathing 1-7 elastic conjunctions are on steel shaft 1-8, and copper dish 1-6 is welded on copper coin 1-5, steel core outer wall
And titanium cylinder 1-1 inner walls have silvering.
It is first that steel shaft 1-8 is horizontal positioned during assembling, the relevant position of steel shaft 1-8 is penetrated after two steel bracing plate 1-4 cars circles,
Then two support plate 1-4 it is cylindrical on be set with the steel core that forms of Explosion composite used by layers of copper 1-2 and steel cylinder 1-3, two
Elastic conjunction two pieces 1-7 conduction copper sheathings are distinguished on the steel shaft 1-8 of steel bracing plate both sides, copper coin 1-5 and copper dish 1-6 are welded into
For integral rear enclosure on steel shaft 1-8, final elastic conjunction titanium cylinder 1-1 forms cathode roll internal conductive structures.
Steel core is made by Explosion composite in the layers of copper 1-2 and steel cylinder 1-3 of the present invention, and steel core possesses conductive capability and branch at the same time
Support ability, the supporting structure after steel core edge rolling as cathode roll.Steel core outer wall and titanium cylinder 1-1 inner walls have silvering to strengthen
Electric conductivity, while lift steel core and titanium cylinder 1-1 elastic conjunctions is bonded rate.
