Background technique
With the rapid development of electronics industry and New-energy electric vehicle, the demand of copper foil is more and more, especially to height
The demand for holding lithium battery copper foil is even more cumulative year after year.Currently, the production of copper foil both at home and abroad generally uses electrolysis method, cathode roll is made
The core equipment of copper foil is produced for electrolysis method, separate unit is worth nearly 2,000,000 yuan.Especially major diameter cathode roll is for a long time by external ridge
It is disconnected, just realize production domesticization within 2016.Cathode roll is the large-diameter revolving body of both ends tape spool, and both ends support construction is all to pass through welding
With axis connection, weld seam is concentrated, and welding capacity is big, and welding stress is easily caused to concentrate, and generates weld crack.Currently, domestic and international cathode roll
The welding of axis and other component all carries out on cathode roll shaft；Consider to cause this and structural strength, cathode roll when cathode roll manufactures
Shaft material selects 45 steel, and heat treatment performance is good, and intensity is high, and plasticity is good, but its welding performance is poor, requires preheating before welding, postwelding is wanted
Annealing is asked, crackle is also easy to produce；If there is weld crack, cathode roll will lead to cathode roll shaft during rotation foil for a long time
There is fatigue fracture；Multiple welding reduces the intensity of 45 steel shafts and plasticity, off-axis easily occurs, cathode roll is caused to be scrapped, cause
Huge economic loss.

Step 4, the cathode roll shaft for being equipped with first steel bushing and first copper sheathing is inverted, repeats step 1~3, assembly
Second steel bushing and second copper sheathing.Complete the assembly of two sets of steel bushings and two pieces copper sheathing and cathode roll shaft.
Step 5, the cathode roll shaft by the assembly of two sets of steel bushings of completion and two pieces copper sheathing is hung on boring machine, and drill bit is sequentially loaded into
On the steel bushing in the mounting hole of safety pin, the pin hole of safety pin is processed on the cathode roll shaft respectively；The pin hole is at this
Depth on cathode roll shaft is 8mm.
After pin hole processing is completed at the both ends of the cathode roll shaft, safety pin is inserted into the hole on steel bushing respectively, and weld
It is fixed.
Step 6, interior muscle is weldingly fixed on one by one on the excircle of reduced diameter section of first steel bushing.
In external peripheral surface successively welding steel, copper sheet and the titanium plate of first steel bushing.First steel bushing end welding is completed
Afterwards, it is inverted cathode roll shaft, in external peripheral surface successively welding steel, copper sheet and the titanium plate of second steel bushing.So far, institute is completed
State the protective case of cathode roll shaft and the assembly and welding of cathode roll other component.
Cathode roll shaft of the present invention and steel bushing interference hot assembly, and pass through the uniform safety pin welding of the circumferential direction of steel bushing outer surface 3
Fixed, limitation steel bushing is circumferentially rotated and is moved axially, and makes steel bushing and cathode roll shaft one.By all welding on cathode roll shaft
It marries again on steel bushing, avoids when cathode roll shaft is repeatedly largely welded with other component and cause welding stress to concentrate on cathode roll shaft
It is injured with crackle, reduces cathode roll and the probability of off-axis occur, ensure that the use reliability of cathode roll shaft.Protective case uses 20
Steel, welding performance are better than 45 steel, do not need weld preheating and post weld heat treatment, so that it may obtain good weld seam, improve yin
Pole roll shaft and other component soldering reliability；And eliminate weld preheating when cathode roll shaft and other component welding and postwelding
Heat treatment procedure reduces cathode roll production cost.
