Description

Electrorefining permanent cathode plate vertical edge is assembled with concealed fastener type and recoverable wrapping strip
Technical field
It is of the invention the present invention relates to the plastic fittings of electrorefining permanent cathode plate (hereinafter referred to as cathode plate) vertical edge Main innovation point category mechanical major.The accessory is mainly used for copper electrolyzing refining cathode plate vertical edge wrapping strip (hereinafter referred to as bound edge). Also the cathode plates bound edges such as cupric electrolysis kind plate, Zinc electrolysis, manganese electrolysis are applicable in.In particular by concealed fastener type and cathode plate assembly connection It bound edge and can be repaired after trough rim is dehisced.
Background technology
Bound edge is used for blocking refining electrolytic production to be connected on cathode plate vertical edge, and to ensure to delaminate, unit can be cloudy by bending The processes such as pole plate disposably remove electrolytic production from cathode plate two sides.
The present invention is mainly used in copper electrolyzing refining.Extensive electrolytic refining course of copper：In 64 degree or so of electrolyte It is middle electrolysis about 10 days, later product there is the cathode plate of copper coin to be hung out, after being cleaned with hot water (60 degree) on machine for cutting charge into pieces two-way bullet Property bend remove copper coin (stripping copper when bound edge a little higher than workshop room temperature of temperature).Enter back into next period.
1. bound edge general situation of development：The longest bound edge of service life is a kind of from the transnational PHS companies import in the U.S., quilt at present Producer is known as bound edge of the cross-section diagram shaped like Fig. 1 made of TIVAR materials.It is two-piece-dress.When assembly, bound edge is on cathode plate Afterwards, by the way that pole is squeezed into bound edge half slot, interference fit is formed, swell half slot, and bound edge slot is made to generate folder to cathode plate Tight holding stress, and frictional force is obtained, form bound edge by frictional force positions with cathode plate assembly connection.It needs size suitable The lasting enclasping force of degree to hold connection to position.4 to 5 years its actual lives.Since it is characterized in pincer structure Design, the stress obtained with swelling vise cathode plate, realize connection positioning.The bound edge of hereinafter referred to as this overseas import For extra large expanding bound edge.And though the expanding bound edge of the same shape of domestic imitation and size is by making great efforts for many years, the service life is only one year Left and right.And domestic industry this imitated bound edge of extensive utilization, it, which has much, representative (have and reaches though initial one kind 5 covers bound edges To 2 year service life, but it needed special plane to assemble, and easily wounds plug etc. in use and premature failure occurs and replaced by expanding bound edge). Below to the expanding bound edge of this this country's production, referred to as this expanding bound edge.The extra large expanding bound edge that the country uses is import cathode Import therewith when plate.Because its price is too high, an occupied fund is excessive, also there are the factors such as decision problem, cause internal copper row This extra large expanding bound edge of the few imports independent again of industry.It is more to have troubled enterprise for the life problems of bound edge for domestic industry Year, and each side never stopped pursuing its service life of raising；It is external to be monopolized for many years with one side of technical monopoly for allowing people to be difficult to crack again, Speech is not transferred the possession of.
2. the essence in bound edge service life：It is following because demonstration need, using the actual life of both expanding bound edges as finally according to According to, force difference when shelling copper by analyzing them, and this species diversity and the two service life are contrasted, to prove the service life of bound edge Mainly due to the structure of bound edge and the soft or hard difference of material, and the stress of bound edge when shelling copper generated is different, the packet eventually led to The side service life is different.The stress and the causality between the service life for namely proving two kinds of expandings and bound edge of the present invention, point made Two kinds of bound edge indexs that analysis result can be actually used are agreed with, and to make demonstration obtain true support, demonstration bypasses The validation problem of invention product, it is also more credible, simpler and more direct.
Since the country could not develop the modified material with TIVAR similar performances, which becomes the key of expanding bound edge Technology.The country have to (intensity is high and creep-resistant property is more preferable etc.) more preferable with mechanical performance polyphenylene oxide (PPO) it is swollen to make Formula bound edge.
Bound edge bears two kinds of main external active forces when shelling copper：First, bound edge is answered with the bending that cathode plate benging generates Power；The peeling force generated when second is that covering copper-stripping on bound edge, and both power can all generate harmful torque in bound edge.Point Two kinds of expanding bound edges of analysis by gap edge, find the reason of influencing the service life, and the item that must reach as new invention bound edge according to this Part finds new solution.
1) the bending stress calculating of bound edge is compared：
The hardness number of TIVAR materials is close with high pressure polyethylene after testing, its room temperature Deflection Modulus of Elasticity is about more than 400. Polyphenylene oxide room temperature Deflection Modulus of Elasticity more than 2315.Sea, this two kinds of expanding binding structures, sizes are identical, and the two bending strain is by the moon Pole plate control is also equal, and the ratio between the two bending stress is exactly the ratio between their elasticity modulus in this way, there is nearly 6 times of gaps.
2) direction, size and the speed of bound edge covering copper-stripping power compare and its influence to the bound edge service life：
(its origin cause of formation need not be gone into seriously the shape of electrolytic copper plate herein.)：Copper removal board bottom side have a very thick fat edges (origin cause of formation be by In the V-arrangement sharp bottom edge of cathode plate, generates edge effect and cause long-pending copper advantage.) outside, other three side of copper coin all very it is thin (including The copper being covered on bound edge), this three sides copper coin is gradually thickeied to copper coin center, and the thickest part of copper coin is in top edge 20 The middle part of more millimeters or less (after electrolysis 5 days, artificially reducing liquid level, formed thin by top copper coin), thickness is up to 17 millimeters or so.
Two pieces of copper piece clips, one piece of cathode plate is bent by mechanism when shelling copper, is generated and is bent with same mandrel, at their adhesions Cathode plate and copper coin must be partly bent with respectively different average bendings, and when copper coin, cathode plate benging in respectively The copper of contact layer and cathode plate surface are in a compressed, Tensile between property face.I.e. in the copper of bonding plane and cathode Plate deformation direction is opposite.In electrolytic copper thickness, because its neutral surface is maximum to bonding plane distance, this makes the part generated when bending answer Power is also maximum.Stress is increased with bending and is increased, and when it is sufficiently large, bonding plane complies with force direction and generates dislocation and detach, and Rapidly to circumferential development.The cathode plate hardness of copper and stainless steel, elastic difference are big, formed copper coin quickly with flicking situation Stripping, and rapidly developed to the direction of middle and upper part bound edge.The copper for being covered in bound edge top be from being approximately perpendicular to bound edge, it is relatively cloudy Pole plate has a low-angle to remove with flicking situation (see attached drawing 1).In this course, since the slot lip of extra large expanding bound edge is special Soft (big with the difference of hardness of copper) and elastic big, when stripping develops to lip, lip is more easy to deform and be moved with copper coin, without It will appear the situation that entire trough rim moves together.Deformation immediately, and wedge-shaped trough rim knot not only first occur under action of pulling stress Structure, other positions are big compared with trough rim for the deflection that slot lip generates, and the part is with the stress at copper adhesion with regard to big.Therefore remove when The separation of copper and bound edge, the lip elastic reset of separated part occurs in slot lip in advance quickly, and the elastic force of lip helps again Separation has been grown, so that the direction that separation quickly covers copper to entire bound edge in order is developed, forms the situation of a kind of " tearing ".Just like It is the same (certain plaster is soft, and copper coin much harder, their " tearing " is differentiated) to tear plaster.In this course, " tearing " action is continuous substantially, and extra large expanding bound edge locally digs action except slot lip, and big portion's trough rim becomes in slot lip Shape is pressed against when removing by copper coin side, does not dig action, significantly reduces the harm that stripping covering copper comes to wrapped belt.And this The polyphenylene oxide material hardness of expanding bound edge is too big, and close with the hardness of electrolytic copper, difference of hardness is small, just as same substance, certain copper stripping When to lip, entire trough rim just a starting by copper strips, and when copper-stripping is hardly formed slot lip locally big deformation situation, and It is the phenomenon that stress increases occur because of the big portion's deformation of trough rim, until very fast separation both when stress is more than stiction force.Process is to divide From there is a pause, the big portion of trough rim is dug, occur overall separation by force trend account for it is leading, it is difficult to which the similar situation torn occurs. Form whole covering copper bonding plane " separation of impact tension fracture type ".When its separating force is much larger than extra large expanding bound edge covering copper-stripping Separating force, and action time is extremely short compared to the former.Two kinds of separation situations are just as to following two ways uprooting weed：As much The power continuously pulled out by root of grass and the power for catching a lot to pull out simultaneously and time when being obviously that a power small time is long, a power is big Between it is short.Both separating forces and action time should there are one the difference more than order of magnitude.
After cathode plate and copper coin Bi -- directional Compression -- Flexure, copper unit is shelled in the middle and upper part on cathode plate two sides, while respectively with one wide The hatchet knife for spending nearly 400 mm wide, along the position for causing " dehiscing " that two sides copper sheet isolates by compound bending, (press-bending can only Most of copper coin on copper coin top is caused to detach) quick insertion, copper and cathode of cathode plate of the riving lower part also in adhesion state Plate.The covering copper of bound edge lower part also end separation moves down position and correspondingly cleaving type detaches with hatchet knife.Due to cathode Plate width is one meter, it is wide compared with hatchet knife very much, separating rate from copper to bound edge direction also because the copper coin that action is formed of riving is elastic It detaches and accelerates rapidly, direction, speed when being developed on bound edge with the bending stripping of above-mentioned copper coin when separation develops on bound edge It is very close, and there are one detach inclination angle.Therefore also occur being similar to above-mentioned separationSea, cover copper on this two kinds of expanding bound edges Situation, that is, form action time of separating force and power that two kinds of bound edges differ greatly.The separation situation of whole bound edge covering copper All so.
Since high molecular material belongs to viscoelastic material, only at a lower rate, polymer segment just comes stress It obtains and moves.In plastics performance test, generally all regulation selects load loading velocity very slow, such as 1 millimeter per minute or therewith The load loading velocity of the same order of magnitude, so low loading velocity can be to height exactly in order to which the loading velocity for avoiding power is slightly larger Molecular material performance test results have an impact.And the action time that the peeling force of copper is covered on bound edge is above-mentioned load loading force The 10000 of action time are to several a ten thousandths.As a result the more same load of trend such as certainly deform, but loading velocity is slow Situation will seriously much.The load of the still more more extra large expanding bound edge of this expanding bound edge is also much bigger.Therefore this expanding bound edge quilt Quickly the anelasticity of the bound edge slot generation high polymer of stroke Moment is much greater energetically.It shows as creep, stress pine Relaxation and in-fighting, only creep stress here is a kind of impact stress of periodic cycle variation.High polymer also has a characteristic just It is：When load action time is slower, strand is in time for displacement, and bound edge is in ductile states, otherwise degraded toughness.This expanding bound edge It is also the performance of poor toughness greatly that more extra large expanding bound edge occurred within the same time, which deforms, relaxes,.Therefore make every effort to reduce impact pair The bound edge service life is extremely important.To there is the action time of the separating force of order of magnitude difference and power, stress condition at this moment is big to creep It is small play a decisive role rather than the creep resisting ability of material, even if this expanding bound edge has used best creep resistant material to make, It is in identical usage time, and creep compliance is also much larger than extra large expanding bound edge.By analyze above it was determined that this expanding bound edge most Dominant failure reason is exactly to cover the harm of copper-stripping power generation.
Alternatively possible is exactly fatigue failure：Although from the point of view of extra large, this expanding bound edge failure mode, even they are disconnected It is also after deformation (relaxation) failure has occurred to split failure, is not the fatigue failure in defining.But more than certain value Under alternation, quick load effect, this expanding bound edge is just first plastically deformed before fracture failure occurs, and this deformation is Caused by alternating load, and it is enough that expanding bound edge is made to fail.Therefore or it should be attributed to fatigue failure.Due to macromolecule The fatigue strength of material is all very low, and the size of alternating load, speed just become whether cause this special shape " fatigue failure " The reason of, and material property cannot be depended merely on to resist this fatigue failure.This point also illustrates：Reduce stripping copper when bound edge stress at One of the key factor designed for bound edge.
Creep, plastic deformation reduce enclasping force, and when enclasping force deficiency, this is swollen, and bound edge will be displaced outwardly, and be formed Empty slot, empty slot is interior to enter electrolyte, the copper of president's evacuation.The arm of force is averagely held tightly also to move outside the bound edge and lengthen, make enclasping force into One step reduces, and is more easy to occur to move outside this expanding bound edge, until this expanding bound edge falls off.Also with because of slot lip during this The appearance of " dehiscing " is limited in " dehiscing " by space, is had evacuation copper scale and is generated, and has residual copper scale in bound edge after making stripping copper Near slot lip, the product copper advantage of residual copper scale is generated in next electrolysis, and bound edge covering copper is made irregularly to grow special It is not big, so-called " nail " copper is formed, entire copper covering surface can also increase in addition to this.This make the stripping copper power of bound edge again it is big greatly Greatly, tension fracture type separation situation has more been encouraged, it is clear that bound edge enters the rapid failure phase.
The function of expanding bound edge trench portions is：It should complete the task of being located by connecting and bending stress is provided again, also to hold Load removes the stress for covering copper and generating, and this high request inherently design defect, also surmounting it to other designs, there are skies Between.Extra large expanding bound edge is used through modified soft material, and the service life illustrates that its material performance index is under the operating mode Outstanding, the contradictory relation between hardness and mechanical performance has been resolved, the good achievement of material comprehensive performance is achieved, has been met The requirement of the structure bound edge to material property.The country could not also copy this material by studying for many years.Common modifications technology It is difficult to reach the requirement under the structure to material property again.
Due to the drawbacks described above of this expanding bound edge, the service life needs to use with the area of section bigger of another early start The bound edge service life of special equipment press fitting is suitable, and two compare, this expanding bound edge only has advantage easy to assembly, makes it to being at present This old-fashioned bound edge could not only be replaced completely at home.Certainly domestic to also have other kinds of bound edge, but its cost performance is poor, the service life It is shorter, without introducing herein.
Brief summary is above-mentioned：The defect of this expanding bound edge is mainly that material hardness is big and the bending stress that generates is not big and therefore not Covering copper can be formed " to tear " formula stripping and generate big impact harm, result and two kinds of expanding bound edge actual life gaps Mutually confirmation.And although extra large expanding bound edge achieves the very high service life, but to keep appropriateness for a long time for high molecular material Holding stress be very difficult, even if extra large expanding bound edge overcomes this difficulty, but the long-term holding stress for keeping appropriateness Or the apparent design defect of extra large expanding bound edge catches up with and surpasses to other designs leave leeway in other words.
Domestic preferably (comprehensive performance)ThisThe expanding bound edge service life only hasSea1/4 or so of expanding bound edge service life.Change a attack Close direction：Start with from binding structure, reduction cross dimensions etc. is changed, and bound edge hardness of the present invention is suitable with extra large expanding bound edge When, it is same to form the stripping situation for covering copper " tearing ", can when delaminating compared withSeaExpanding bound edge stress is greatly lowered.When right When bound edge life requirements of the present invention is higher than this expanding bound edge and less than extra large expanding bound edge, with the preference of following present invention bound edge, It can reduce to material requirements, bypass material difficulty, the modification soft material that can be provided with domestic existing modifying plastics producer, but It can easily surmount this expanding bound edge service life (two to three times) very much.And when future, material development aspect had breakthrough, to surmountSea The expanding bound edge service life hides the foreshadowing.And with the long discount button bound edge of the present invention most preferably scheme, it surmounts currently all bound edge Service life is realized " bend is overtaken other vehicles ".Mostly important independent intellectual property right can also be obtained simultaneously.
Invention content
It is in order to which the present invention provides following scheme the technical issues of solving bound edge short life：With completely new concealed fastener type structure The part for connecting positioning on cathode plate as bound edge of the present invention shifts to change binding structure and reduces bound edge ditch Slot is born, and the present invention is preferably and most preferably scheme is in stress, the achievement obtained in terms of the service life difference.Optimal case is using most Rational tubular structure, using outstanding pipeline extrusion technique, shorten the bad mechanical property even surmounted with extra large expanding bound edge Away from.Its material, structure determine after groove is dehisced, and to extend the service life, using not dismantling wrapping strip, dehisce interior sundries in cleaning Afterwards, Special reset tool (491) is clamped, more piece matches half module (494) elastic force reparation and dehisces after heating, dehisces to eliminate after cooling, Bound edge is continuing with.
1. preferred embodiment (multiple choices made by working condition difference) surmounts the domestic bound edge service life as mesh using double Mark, it may have very big value, concrete scheme are made than cathode plate thickness on the position inside bound edge and near cathode plate vertical edge The slightly larger hidden discount pair of size is spent, joint groove is come the bound edge that is located by connecting.
Its material, structure are：Two bottom edge of groove, which is designed with, subtracts stress concentration circular arc sulculus, it with hardness be Shao A50 compared with Soft hot melt modified poly ethylene plastic production, lip is very soft, participates in the also multiple hidden discounts for co-locating connection, hidden discount is by matching Discount and button cave composition, discount is produced in wrapping strip, matches button cave then on cathode plate；Discount is produced on cathode plate, Button cave match then in wrapping strip, hidden discount, groove collective effect make wrapping strip be positioned on cathode plate, and opposing cathode does not occur The movement of plate, the more existing bound edge of groove will be shallow, and Fig. 3 shows that button wrapping strip cross section relatively has wrapping strip and greatly reduces.This It is preferred that bound edge is common that：Because shape additional stress is small when bound edge shape is the suitable conjunction extrusion process such as round bar shape and is bent Shape subtracts stress concentration arc opening plug 417 with what hot melt was made bound edge bottom end.Specific concealed button structure has following a variety of hidden discounts It is secondary：Hemispherical button cave 414 corresponds to discount 416 in bound edge；Bidentate button cave 421 corresponds to discount 423；It is smaller compared to 423 diameter of discount Hole when button cave, be press-fit into place by force after heating discount 423；It is similar with 423 shape of discount, but diameter is small and sharp cone distal band It is buckled to discount, button cave is not set on bound edge, discount is pressed into bound edge by force after the heating；Oblique straight cylinder discount 425 can also be oblique Curved cylinder discount, corresponding oblique straight cylinder button cave and tiltedly curved cylinder button cave, is used cooperatively block 426；In fixture hole 62 and position line Tapping band screw thread button cave, paired sharp screw thread discount are oriented on wrapping strip bottom edge with special screw tap 531 under 532 assistance Sharp thread head initial position is determined on the signified corresponding direction of position line 532, is welded on cathode plate vertical edge, is assembled this bound edge The method that Shi Caiyong is pressed by force is assembled, and rear male and female screw thread just mutually agrees with to form hidden discount pair in place, avoids newly-increased stress；Only Sharp screw thread discount heats without button cave in bound edge and relatively moves pointing screw thread discount by force after sharp screw thread discount and enter in bound edge Reach hidden discount function after cooling, but its appearance can be shown in local bulge, there is additional stress；The horizontal button cave 418 of column, corresponding column are horizontal The two-way ironed molding of ironed tool 542 of the wherein horizontal button cave of discount 419, melt squeezes out from hole wall when scalding hole, is cut off after cooling； The discount 431 being connected with two cell walls in bound edge, it corresponds to button cave 433；Deformation of discount 431 432 etc., it corresponds to button cave and exists Respective change is done on the basis of 433；The discount 441 being only connected with one side cell wall, it corresponds to button cave 442；Contraposition is inserted into cathode plate The discount 445 welded again in hole, it corresponds to bound edge internal buckle cave 446；To save map sheet, is concentrated on cathode plate and draw a variety of discounts 447；448；449；4491；4492 they one of, the matching button cave of same shape in corresponding bound edge；It is milled out on cathode plate vertical edge Flange 4493 is got after correction of the flank shape with knocking after plush copper 4494, it is worked as discount, corresponding bound edge subtracts stress concentration circular arc 413 and works as Cave is detained, then sets positioning pin in bound edge top shelf and the bound edge is prevented to move up and down；Oblique in cathode plate to buckle cave 451, it corresponds to bound edge Interior discount 452, the discount can break through bound edge and dehisce；Steel wire buckle cave 461 is made with ironed method in bound edge, it corresponds to and is welded on The discount 462 of cathode edges of boards；Discount 472 is welded on cathode plate, it corresponds to two kinds of button caves 471,475 and forms the two of different bound edges Kind hidden discount；The fixation strip discount 476 that discount 472 deforms, the corresponding button cave 478 communicated completely with bound edge groove, it Without reduction stress concentration circular arc, but it has most deep trench in button bound edge, influences the bound edge service life.
2. most preferably scheme：It is that discount is lengthened from 472, develops into 476 and remakes including the groove depth and slot bottom shape etc. Differentiation, obtain optimum structure bound edge, the softer modified poly ethylene plastic production that it is Shao A50 with hardness, lip is very soft, knot Structure is：After long button bound edge 480 is attached to position, such as with material with strong elasticity：The titanium steel of 316L stainless steel hard springs silk, spring processed Silk, the prodigious plastics of hardness such as PEEK etc., manufactured strip discount 487 are inserted into button cave 481 and discount seat 486, the molten dress of reheating Plug 485 with bound edge upper/lower terminal becomes the special hidden discount pair connection of shape, completes the long button bound edge and be located by connecting, should Long button bound edge cross section relatively has wrapping strip and greatly reduces.Long discount bound edge is made using existing outstanding pipeline manufacture craft After cast, (self-control plane, milling machine can be used with fixture processing groove, slot hole, plant capacity very little realizes family's metaplasia with machining Production, reduces cost) circular arc bottom groove 4891 and the connection of Button Block slot hole 482 hole 483 are obtained, and good mechanical performance is obtained, It shortens and trough rim is carried out with minimum distance oblique with external long-life bound edge this respect gap, shallow and larger arc slot bottom 4891 The position of drawing, shows to support and slow down well percussion, and the bearing that long discount provides bound edge stress is because position is good And effect is good, structural advantage highlights.Damage is hit to mitigate, all bound edge bottom ends (in terms of vertical cathode plate direction) have 1 Spend upward oblique angle so that born by bottom edge 32 when bound edge bottom end vicinity is hit.
Structural advantage can solve life problems be because：The button bound edge has following strong point, especially:Due to button Bound edge very little the positioning strength required when shelling copper, the hidden discount is secondary to be sized to very little and can meet and position need It wants, the mechanical performances such as intensity of button cave or discount button type bound edge influence small in this way, and are suitble to make on relatively thin cathode plate Discount or button cave.This especially small hidden discount pair has suitable difficulty in manufacture, and domestic industry is to the force analysis of bound edge It is not deep enough, do not recognize the benefit that it can bring.I.e. presence I had never expected that the so small hidden discount pair of making can meet and be positioned to The technology prejudice asked will not use this " hidden discount " formula structure naturally.Especially：The section structure of button bound edge is a circle Shape, gash depth only have the 1/4 of existing bound edge to arrive a little more than half, and nearby there is the circle all thick and solid compared with other types bound edge on slot bottom side Shape structure, and the cross dimensions is minimum in various bound edges, this structure adds the good elasticity of material, to bearing to shell Generated impact force has good cushioning effect when copper.In preference, the slot bottom side suffered stress when stripping covers copper Very little, but for prevent stress concentration be also provided with two anti-stress concentrations R very littles arc groove.Especially：It is than expanding packet Side groove depth wants half as large, and has the soft groove lip about the same with extra large expanding bound edge, can form the covering of " tearing " Copper-stripping situation.Especially：What it is due to button bound edge is that the good material of hot melt makes, for the anti-stress of bound edge bottom end Ditch notch is concentrated, using the method for local thermal deformation, after so that the exit or entrance of a clitch is deformed, the plug for blocking electrolyte can be formed, it is not necessary to another With special plug.Especially：The soft elasticity of button bound edge matter for detaining cave shape such as 414 is good, in smaller extruding force when assembly Under effect, double inclined plane discount can easily squeeze button bound edge groove and enter button cave, and groove elastic reset forms concealed fastener type connection；It is right Discount is for the button bound edge in bound edge, cathode plate is extruded into after discount position distortions buckles cave position and flick, and discount enters position, is formed Button connects.It assembles fast and convenient etc..Preference is especially：Shell the main action direction of copper power on vertical cathode plate, detain cave or The stripping copper power very little that discount is born.And button bound edge is controlled when being bent by cathode plate, will not form bending at button cave and turn Point avoids the damage that stress concentration is brought.
One, the advantages of button bound edge and good effect：First to detain the button bound edge (hereinafter referred to as button bound edge) that cave is 414 To represent relatively service life demonstration is carried out with extra large expanding bound edge：
1. we are compared first button type bound edge with stress of the expanding bound edge when shelling copper bending.To simplify the calculation we First assume button packet
Side is identical as the extra large hardness number of expanding bound edge：
Rigidity is the ability that material resists flexural deformation.They bear the width of compound bending successively under the conditions of same when delaminating It spends identical.Under external force, the stress of generation is determined by itself rigidity to bound edge.And rigidity is elastic modulus E and cross Product of the section around the moment of inertia I of its neutral axis.Because with hardened material, their elasticity modulus are identical under the conditions of equality of temperature, rigidity it Than the ratio between the moment of inertia for being equal to them.The ratio between bound edge stress is the moment of inertia the ratio between of the section around its neutral axis.Attached drawing 3 be with Ruler draws extra large expanding bound edge and button bound edge cross-section diagram in proportion.According to common cross sectional moment of inertia calculation formula
It is round：IX=π d4/64
Rectangle：IX=(B H3+bh3)/12
There is rectangular channel in circle：IX=π d4/ 64-bh3/12
Extra large expanding bound edge section is as tired through formula calculated value such as the China and foreign countries Fig. 3 expanding bound edge with above-mentioned after being subdivided into polylith rectangle It is about 7012mm to add rear cross sectional moment of inertia3
Button bound edge is 2650mm through formula calculated value according to button bound edge in common cross sectional moment of inertia such as Fig. 33
It is about 2.6 two-value relatively to be obtained the ratio between their the moment of inertia：1 namely their the ratio between bending stress.
2. the force action line of above-mentioned bending stress is shown in W1 and W2 center of gravity line in Fig. 3 in the immediate vicinity of bound edge.And because Their bending stress is that cathode plate provides, and in the trench, we can pass through power to the position of the resultant force of this bending stress Translation go on center of gravity line, but a moment loading will be added simultaneously on groove bottom edge.Obviously the weight of sea expanding bound edge Heart line compared with button bound edge center of gravity line further from groove bottom edge, and the two this gap is extra large expanding bound edge bending stress to groove The reason for answering torque much bigger on bottom edge.Area in bound edge section other than cathode plate is bigger, power of the bending stress to bottom edge Square is bigger, and the burden of groove is bigger.
3. furthermore swollen, button bound edge the gash depth in sea differs one times, even if identical bending stress is to groove bottom edge Torque is answered to differ one times.
4. under the action of being in swelling stress due to extra large expanding bound edge, stress is very complicated when bending.And extra large expanding bound edge Tension force so that its integral hardness is increased so that actual elastic modulus E is increased, and actual flexion stress is also with actual hardness It increases and increases.
Consider the Overlay that aforementioned four factor is likely to form, extra large, button bound edge bending stress is to bottom edge Answer torque ratio value can be compared with the ratio between the moment of inertia of the two 2.6：1 is much bigger, it should which there are one orders of magnitude or so.And Hai Zhangshibao Side it is big answer torque corresponding groove bottom edge especially small loaded area nearby, referring on the left of Figure 14, and button bound edge it is small answer torque The much bigger loaded area in corresponding groove bottom edge, referring to 2 left sides Figure 41.From bound edge section, button bound edge above two by When power, it is involved in stress deformation within the entire long circular arc of button bound edge, stress surface is relatively uniform, without expanding bound edge on slot bottom side On the left of a neighbouring king-sized position of fritter stress (14).412 left side of material of large area, energy near button bound edge slot bottom side Enough to provide opposite expanding bound edge much bigger elasticity, this thin structure of expanding bound edge is the another big defect of design.Button This region of bound edge is very big, has good buffer capacity.Button, stress difference of the expanding bound edge on this key position are away from certain The service life of bound edge can be had an impact.Button bound edge is detained by torque, buffering stress to reduce with structure special advantage to reduce Formula bound edge slows down trough rim deformation by the degree of creep rupture.
The tension force of extra large expanding bound edge is increased close to slot lip portion stress, if the material mechanical performance phase of two bound edges Together, extra large expanding bound edge is more easy to generation local creep than button bound edge and generates " dehiscing " gap, and is gradually increased.That is the two service life If quite, the relatively extra large expanding bound edge of requirement of the button bound edge to material mechanical performance is with regard to much lower.
This expanding bound edge in authors observed use, there is the deformation of local groove lip and after generating small " dehiscing ", as long as Unilateral " dehiscing " is difficult to long copper in 0.4 millimeter on the cathode plate in " dehiscing ", but grows one layer of white attachment, it is cloudy After pole plate hangs electrolytic cell, during shelling copper, interior electrolyte dry-out of dehiscing, this difficult dissolving salt of precipitation barium salt etc. one, its energy It is deposited prior to copper, and hinders the deposition of copper.Also just confirmation button bound edge can normally make within 0.4 millimeter of unilateral " dehiscing " With just will appear " dehiscing " director copper and covering copper abnormal growth phenomenon more than this numerical value, button bound edge at this moment just enters Itself opposite flow gradually accelerates the stage, dehisces if not repairing, and bound edge will fail.
Due toSeaThe ratio between expanding and button bound edge harmful bending stress square suffered when delaminating about an order of magnitude.This is swollen The hardness ratio of formula bound edgeSeaExpanding bound edge is 6 times big, this expanding bound edge just will more differ 80 times with this ratio of button bound edge.
Compared by the calculating of analysis and bound edge bending stress to covering copper separating forceSea, this two kinds of expanding bound edges Afterwards, it obtains to draw a conclusion：Under the premise of the structure of both bound edges and shape are nearly identical, applying working condition is identical, it When shelling copper by biaxial stress, impact differ greatly, on the bound edge of non-" tearing " formula of this expanding bound edge cover copper detach time slot The strain that side generates is very big.Necessarily lead to big lag and in-fighting when this strain is replied every time, the advantage of material property is not It is enough to offset the consequence that the two-way strain that this differs greatly generates, it is inevitable to cause the two deformation to differ greatly.SeaExpanding Bound edgeTIVAR materialsThough mechanical performance it is good, but the bad mechanical property of the polyphenylene oxide compared with this expanding bound edge, and it The service life then in turn differ 4 times, main cause is exactly that two kinds of bound edge hardness differences make stress (square) differ greatly.It is i.e. full The bound edge material softer service life is longer after sufficient certain condition.Soft advantage highlights herein, is more than the other advantages of material, becomes bound edge and set Count the key link that must take into consideration.
Two kinds of expanding bound edge failures are compared：The above result of calculation and the service life that they differ greatly all prove, Hai Zhangshibao While since its stress (torque) when shelling copper is much lower compared with this expanding bound edge, it can keep effective enclasping force to make bound edge not for a long time It generates and loosens displacement.Stress impact when the periodic cycle stress that the two is born differs manyfold, covering copper-stripping more has number The difference of magnitude.Anelasticity will occur when will all material strain be caused to reply, shows as creep, stress relaxation and in-fighting etc., it is interior Consumption generates aging；Furthermore periodic cycle stress when this expanding bound edge covering copper-stripping is significantly more than its fatigue limit.They Collective effect promotes this expanding bound edge trough rim and occurs local plastic deformation too early (trough rim " dehiscing " occurs and causes mistake successively Effect) finally occur and prematurely generate clamping stress and relax to cause to move failure outside bound edge with crackle.Compare the conclusion obtained It is：Reduce stress (torque), impact is to improve the key measure in bound edge service life, the production technology of modified material and bound edge is not the One.
The author carries out Follow-up observation to the situation after the bound edge use of this expanding, finds bound edge maximum breakage in different bound edges On be random distribution, and the bending of above-mentioned bound edge and covering copper-stripping force-bearing situation be also equally distributed, which does not occur Point is to be particularly easy to spot failure.This has also confirmed the correctness of analysis.
Button bound edge is obtained helpful with more reasonable structure：Bound edge groove when shelling copper will bear trough and be pulled outwardly The quick torque opened.Referring to Fig. 3 and following comparison sheet：
Section near bound edge groove bottom edge is bigger, and unit area bearing capacity is also more advantageous to bound edge with regard to smaller.It is swollen from sea Formula bound edge section sees that forced area of the button bound edge at groove bottom edge is large semicircle, its bearing stress face is relatively especially big, Leading to extra large swollen, button bound edge, unit area stress difference is very big at groove bottom edge when shelling copper.The elasticity that the latter is provided is opposite It is much bigger, buffer capacity is much better than.Relatively existing bound edge, button bound edge make button bound edge to shelling copper power with more reasonably structure There is ability to bear outstanding, substantially increases various stress damage abilities of resisting, and its area phase other than groove bottom edge To minimum, it is minimum that when bending, generates additional moment.And the simple shape also particularly advantageous making for making forming and reducing product Remain internal stress etc..
Due to the long-term strain for holding stress generation tightly of extra large expanding bound edge, relaxation is necessarily will produce, relax degree Depending on relaxation modulus, stripping copper when strain size and be hit load the case where.And button bound edge only has minimum assembly interference Stress, relaxation trend is very small naturally, this stress also has compensating action to " dehiscing ", can extend button bound edge and " dehiscing " occurs Time.
By the analysis of above-mentioned stress situation, though do not affirm bound edge covering copper-stripping and that stress of bound edge bending stress To bound edge aging effects bigger, but all prove that the more extra large expanding bound edge of button bound edge has greater advantage in stress.Button bound edge There are " tearing " situation when covering copper-stripping, the condition of " tearing " formula separation with extra large expanding bound edge：From extra large expanding bound edge section Structure sees, is in tip-angled shape at lip, is drastically thickeied with heavy grade at adjacent trough rim therewith, along with playing the role of tension force, slot The hardness on side is in state is suddenly increased, and when shelling copper, other position distortions differences of lip and trough rim are big in this way, and as a result lip is divided in advance Situation " is torn " from formation.And identical as extra large expanding bound edge at long button bound edge lip, extremely shallow gash depth and long button The strength of bound edge center slits supports, and also forms " hardness of trough rim is in suddenly to increase state ", is also easier to form stripping copper certainly When " tear " formula separation, i.e. separating force smaller, its more extra large expanding bound edge is more advantageous, this advantage outstanding is set as one The basis of meter.Button bound edge more has advantage outstanding with respect to other bound edges.On the basis of these advantages, pass through existing special manufacturer The polythene material that family's technology is modified, it is believable so that button bound edge is reached the service life of extra large expanding bound edge.
Two, the advantages of long button bound edge and good effect：Long button bound edge is a kind of special shape of above-mentioned button bound edge, It relatively above-mentioned button bound edge the characteristics of be that duration discount of delaminating also provides most of bending stress to wrapping strip, and with covering copper The anti-moment of reaction of the torque generated when stripping, rather than groove is depended merely on to balance this torque, button bound edge is compared, this sets Meter significantly reduces the burden of groove again.The bending of groove burden is greatly reduced compared to other bound edges, stretches iso-stress, solely The shallow trench played the role of is mainly used to occupy-place and forms soft lip, and strip discount and discount seat carry major part and be bent and cover The stress generated when lid copper-stripping, plays the role of backbone, shallow and there is larger arc slot bottom 4891 minimum distance to be carried out to trough rim The effect of oblique pull shows to support well and what circular arc had slows down percussion, and structural advantage highlights.
Overall merit：The long more extra large expanding bound edge of button bound edge：Shorten in product mechanical performance and is even more than it；And it is real Border stress (square), and it is significantly smaller than it；The two can form covering copper and " tear " formula stripping；Actual life should be more than it；Add On readily dehisce not dismantling and can repair and the increased service life, the service life surmounts suspenseful, and may surmount very much (needing time check)；Except disposable discount seat assembly cost height, after-cost will be significantly less than it.
It and extra large expanding bound edge ratio：One is reprocessed with customized tubing, and one is wall unevenness and there are the different of wedge angle Shape material, craftsmanship gap is huge, (customized tubing is the product that existing mold is slightly changed to product yield, and production scale is exactly The production scale of tubing.) gap is huge, the latter's mold category single-piece makes, Development Level is limited；Due to the program be utilized it is existing The highly developed manufacture craft of polyethylene pipe, such as to have the PE100 pipelines for having developed to the third generation so far to show excellent The Process ba- sis of elegant mechanical performance makes up long button bound edge and the difference in extra large expanding packaging material performance using the achievement of this respect Away from.This is because single for technique, extra large expanding bound edge is special-shaped extruded product, when material identical its mechanical performance just less than Tubular member, therefore under existence conditions, the sure diminution of gap of final products mechanical performance perhaps has the possibility surmounted.It orders Tubulation material is machined again to be made long button bound edge (480), and groove has been not necessarily to provide the bending stress of bound edge, and also lip is dehisced Afterwards can renovation technique (and each tension force difference is big after extra large expanding bound edge failure, is uniformly restored to suitable tension force and is operating It is upper infeasible.), it is suspenseful that long button bound edge surmounts the extra large expanding bound edge service life.Since the gash depth of long button bound edge only has The 1/4 of the most shallow extra large expanding bound edge of the gash depth used now, it is clear that bound edge have dehisce when, the latter enter electrolyte Capacity to be significantly smaller than the former, especially the former have occur to remove existing part empty slot outside bound edge in the case of, two kinds of bound edges The former wants greatly more to the amount for the copper sulphate liquid being extruded in dehiscing when shelling copper, and the copper sulphate liquid being extruded is sprayed on copper coin On, product quality will be influenced, especially very big on products export influence, intractability is big.It is also existing that this, which puts long button bound edge, What bound edge can not be reached.
The material that the more existing bound edge of bound edge of the present invention uses will much less, make the relatively extra large expanding bound edge of required precision Much lower, some processes can realize that family oriented produces, and cost is very low.Extra large expanding bound edge can reach longest 5 under rigors Service life more than year, it was demonstrated that the weather-proof ability of material disclosure satisfy that more for many years under the preceding topic of normal use.
The benefit of three, buttons, long button bound edge long lifespan：It is greatly decreased and production is caused very greatly due to frequently replacing bound edge Negative effect, be greatly decreased replace bound edge manpower, be greatly decreased to waste and old bound edge treating capacity (existing useless bound edge be bonded with compared with More copper particle, separating difficulty is big when processing, it is general using recycling copper is burnt by the way of, this had both had more baked wheaten cake processing mode and had brought Pollution, also results in the waste of this recyclable material.), be greatly reduced enterprise's production cost (with produce per year 300,000 tons of electrolytic coppers factory be Example, bound edge ownership add spare part amount at 120,000 or more, using the button bound edge, estimate to save for 1 year compared with this expanding bound edge The dosage of million yuan of total cost three to four, national copper smelting plant bound edge is huge.) etc. many-sided benefit.Tremendous economic will be brought sharp Benefit and emission reduction benefit.In fact, the service life length of bound edge, which is copper refining enterprise already, pays special attention to point.
