Abstract
A pre-straightened metal wire consisting of a copper alloy and having a diameter of less than 6 mm and a mechanical strength of 400-750 MPa is packaged in a cylindrical drum in such a way that, when it is unwound, the wire is straight, with a sag of less than 5 mm per metre, and can be fed directly to a bar turning machine.
Description
The present invention relates to pre-stretching copper alloy wire is encapsulated into method in the bucket with wire rod around web-like, be used for special requirement wire rod necessary stretching various application scenarios before it uses.
Generic term " wire rod " is following will to be used for representing that all can be with the semi-finished product that send around roll form, even those of on-circular cross-section.
The vanning of pre-stretching steel wire rod that is used for the feeding automatic welder(welding machine) is known.
In current welding machine, wire rod is by the constantly feeding of sheath pipe quilt.In order to improve the automatic capability of machine, wire rod is installed in 250 kilograms of buckets.Stretching in advance before wire rod is placed in the bucket, make may obtain a kind of when wire rod when rolling wheel is emitted not with any remaining solenoid or curling product.This just may reduce the friction of wire rod in sheath pipe the inside, and guarantees the glacing flatness of wire rod in the free section (" section of stretching out "-approximately long 30 millimeters) at solder joint place.
Pre-stretching is the (see figure 1) that realizes in the following manner:
-the wire rod of emitting from a rolling wheel is by a series of stretching running rollers, and can keep the major diameter capstan winch of wire rod glacing flatness in advance to drag by one;
-then, two pairs of non-motor-driven running rollers are arranged on by within two orthogonal planes of wire rod axis and be driven and center on wire rod and rotate, and give that wire rod is a kind of to be reversed.Wire rod is placed in the bottom of bucket subsequently by cylinder guiding until it with a kind of form of the spiral coil of wire;
-bucket is along with it is descended by filling, so that the gap between the Free Surface of wire rod and this cylinder bottom remains unchanged;
After-bucket was loaded, a plastics ring was placed in above the top solenoid of wire rod, and this ring is connected in the bucket bottom by an elastic straps, and product can be held in place.
This technology is used for by the made welding wire of the steel of height strain hardening, and this welding wire mechanical strength is generally 600 and 1,200N/mm
2Between, and from 0.8 to 1.6 millimeter of diameter.
Pre-stretching technology can make pre-stretching suitably slippage in the sheath pipe of one tens millimeters long of wire rod, makes to be the welding equipment that the heavy wire rod storage facilities fixed is supplied with a kind of activity all the time from a kind of itself.
Purpose of the present invention specifically, is to improve and is used for fine turning by copper alloy, particularly half-finished current techniques of making of brass.
In fine cutting, two types machine or method are arranged:
Class1: wherein machined is finished specially with a rotary cutter, and material is transfixion then,
Type 2: wherein a fixing cutter is used for a kind of material of rotation, such as being set forth in the sort of among the patent application WO 81/01378.
In order to ensure the mach optimum precision of high speed, wish that material rotates, and cutter keeps transfixion.This just requires material to provide with the form (general 3 to 4 meters) of less straight the pipe nipple that is enough to rotate of length.
In order to make these pipe nipples, they also use " bar " vocabulary to show, generally adopt one of following two kinds of methods:
Method A: each bar produces the family expenses seven-roll Abramsen machine by wire rod and makes.
Fine turning machine is equipped with " a bar container " that is called " bar feeder " in the case, in order to be provided with bar to fine turning cutting tool.
This technology has following shortcomings:
* owing to existing bar feeder and lathe technology, bar must be fully straight, and not so bar will be stuck in the bar feeder, and perhaps they can during turning cause vibration, and this vibration can be the reason of bad geometrical defect on the part that processes.
In order to ensure bar is fully straight, and the producer of brass rod must adopt special wire straightener device (seven-roll Abramsen machine), and price is higher, secondly also has, and stretching speed is markedly inferior to pull speed, thereby production capacity greatly reduces.Owing to these two kinds of reasons, this method needs higher expense.
* because the ability of bar feeder is limited to tens bars, the automatic capability of lathe also thereby be restricted.The bar feeder of for this reason must whenever regularly reloading in several hours, this can cause adverse effect to productivity ratio of lathe operation person.
* owing to the spatial constraints during the bar accumulating, their length is restricted (about 4 meters).This can hinder their use, because for each used bar, and about 200 millimeters, perhaps 5% of its length, be wasted.
Method B:
Producer forms each wire rod around volume with wire rod, and its Unit Weight generally is 250 kilograms.Each wire rod among volume is placed on cylindrical fiber can, bucket in the bottom by wooden base plate sealing, and at the top by a demountable wooden or casting coping capping.
For forming this wire rod around volume, brass wire producer just in time applies slightly a plastic deformation it being encapsulated in the bucket with the forward direction wire rod, so that give its natural curvature, its diameter is similar to the diameter of bucket.This point is essential, so that each solenoid is with the uniform mode position that is ranked, and eliminating the risk of during accumulating, tangling, and the risk of during the wire rod debatching, blocking.
At turning equipment place, wire rod is pulled out from bucket by means of a special uncoil-stand, after this is straightened by a rotating frame that has roller, and cut into chunks by a shearing tool in the back again.Thereby, obtained to rotate each bar that is used for turning.
A compares with method, and method B has the following advantage:
* the preparation of each bar is to carry out simultaneously during the turning with last bar.Thereby, stretching operation, much more quick than turning, do not cause any loss of productivity ratio.
* a bucket holds about 10,000 rice noodles materials, represents several thousand bars.Thereby the automatic capability of lathe wants high number in hundred times with respect to method A.
* the length restriction of bar no longer is subject to and transports and encapsulate, but relevant with operational space, turnery the inside.Thereby, might process longer bar at least in theory, thereby reduce the wastage (waste material is less than 5%).
Method B thereby be subjected to fine lathe operation person's welcome day by day, especially those are engaged in the people of processing in enormous quantities, and this moment, large-duty demand was absolutely necessary.
But, method B has following shortcomings:
A) different with method A, wherein the seven-roll Abramsen machine of brass wire producer outfit limited quantity is used to make bar, and this moment, lathe operation person must install a large amount of this kind machine (seven-roll Abramsen machine of each lathe).Thereby seven-roll Abramsen machine must be fairly simple model; Not so it will represent a sizable investment.
B) but, owing to adopted " simply " seven-roll Abramsen machine, stretching accurate performance much lower with regard among the ratio method A, and bar has a kind of several centimetres amount of deflection usually.Lathe operation person has partly corrected this defective by the feed arrangement of revising lathe, and mode is, in mach process, the bar envelope is rolled among the oil-filled sheath pipe.During oil bath can make bar during turning automatically the oneself looks for.But, because each bar is not fully straight, so the precision of turning is not the best (10 micrometer ranges; Nominal value+10 micron, nominal value-10 micron, perhaps decide on various situations nominal value+/-5 micron).
C) method B is limited to than being easier to stretching various wire rods, can't be accurately stretching and have some wire rods of major diameter and high mechanical properties.Thereby method B can not be used for diameter greater than 3 millimeters wire rod, perhaps, have at wire rod under the situation of high mechanical properties (being generally 700 newton/square millimeter level), even those littler wire rods.
D) when machined very farm labourer's part, particularly when machined be when depending on rotary cutter to finish, the excessive residual deflection (skilled person in the art is referred to as " brass memory ") that adopts wire rod can cause workpiece to have straightening device can't to eliminate: for the workpiece of one 40 millimeters long, amount of deflection is 0.15 millimeter level, and franchise is 0.07 millimeter.This problem occurs on two types the turning machine: wherein material keeps actionless those lathes (Class1) and material to be in those lathes (type 2) among the rotation.In the case, must make wire rod stand a kind of complementarity heat treatment prior, that be made of a kind of part recrystallization of alloy around volume, the cost that increased of work is very important like this.It can obtainable amount of deflection be workpiece 0.05 millimeter, very long (40 millimeters) that this heat treatment makes.
The objective of the invention is, provide by an Albatra metal-, generally is the method for packing of the wire rod made of brass, above can eliminating at method A and the pointed various shortcomings of B, particularly at method B a) to d) those shortcomings, that is:
1) no longer be that each chassis bed needs a seven-roll Abramsen machine,
2) obtain the big or higher turning operation of speed of a kind of precision,
3) available wire rod expanded range comprises the wire rod that has than major diameter and/or higher mechanical strength grade,
4) do not need prior heat treatment, greatly reduce or eliminated residual deflection in farm labourer's part very.
Secondly, according to method for packing of the present invention,, can not increase restriction significantly for wire rod producer although it has solved the variety of issue that lathe operation person faced.
Of the present invention first themes as pre-stretching metal wire rod is packed in the cylindrical shape bucket, wherein, this wire rod is a kind of copper alloy wire, its diameter is less than 10 millimeters, mechanical strength is between 400 MPas and 750 MPas, and the mode of encapsulation makes that it is straight when the wire rod debatching, amount of deflection is less than 5 millimeters/meter, and direct feeding one turning machine.
According to the second way of using this first theme, this is straight and amount of deflection less than the wire rod of 5 millimeters debatching, be fed a turning machine that is equipped with a seven-roll Abramsen machine.
In the case, when it left seven-roll Abramsen machine, wire rod had one less than 0.5 millimeter/meter amount of deflection, a kind of necessary level of high accuracy machined of being engaged in.
Owing to use the prestretching straight line material of (turning) first theme, preferably select brass as copper alloy, but as following will pointing out, other " firmly " in or " crisp " also can adopt in the alloy of brass.
Come from the energy that it is put aside during must being limited in prestretching straight line material and being placed in the bucket particularly for the diameter of prestretching straight line material and the maximum constraints of mechanical strength.Exceed certain limit value, the energy of this savings just may be big can't hold by one barrel protective case, even exist just in case drum rupture and the danger that cause stress all to discharge.
The applicant finds, encapsulates wire rod according to the present invention and can make the following possibility that is selected to:
* be according to method B, do not use the seven-roll Abramsen machine that has rotating frame and the feeding turning machine can be simplified the adjusting and the maintenance of this lathe so greatly, and significantly reduce investment;
* still according to method B, use has the seven-roll Abramsen machine of rotating frame and the feeding turning machine, making like this may be by allowing to use than major diameter (up to 10 millimeters rather than 3 millimeters), and the various wire rods of higher mechanical strength (up to 750 MPas rather than 650 MPas) enlarge the scope of the wire rod that can use according to method B, and significantly the machined precision is brought up within 5 microns the scope: nominal value+5 micron, nominal value-5 micron, perhaps nominal value+/-2.5 micron, this will decide on various situations, this the also feasible wearing and tearing and Turning Tool Breakage rate that may reduce on the cutter: thereby, the brass par of every lathe tool turning is from 2,000 kilogram is increased to 5,000 kilograms.
Under any circumstance, the invention solves productivity ratio and/or credit rating problem with substantial economics.Secondly, the solution to this problem was impossible to expect or propose by the device that is proposed with the steel wire rod about welded encapsulation in the prior art originally.
In fact, for the expert of a brass turning technology, wire rod stretching is understood that a kind of requisite operation, is with inseparable according to the machined of method B.The probably unexpected forever possibility of eliminating the stretching operation of wire rod of this expert.
On the other hand, this expert is different with skilled person in the solder technology, and known devices can't constitute certain benefit gained from others' wisdom general or association area for the expert aspect the brass wire turning in steel wire rod welding field.
At last, because difference to some extent on the problem to be solved is being arranged, even this turning expert has the knowledge of using pre-stretching steel wire rod in welding field, he also will not expect, with the device of slippage can be enough to the be shaped bar and needn't stretching wire rod so that steel wire rod passes a sheath pipe.
Of the present invention another themes as packs pre-stretching metal wire rod in the cylindrical shape bucket into, wherein, this wire rod is a kind of mach wire rod of electric spark that is used for, generally comprise a Cu-Zn alloy outer, diameter is between 0.15 millimeter and 0.35 millimeter, and mechanical strength is between 500 MPas and 1,100 MPa, the mode of encapsulation makes that wire rod is straight when working as its debatching, and the amount of deflection that has is less than 30 millimeters every meter.
The various many patents of being configured in of the mach wire rod of electric spark that are used for are narrated to some extent, and such as European patent 526361-A1 number, it is the patent of declaring with the applicant's name.
The applicant notices that the method that the use of being found is used for the wire rod of turning also can be applicable to be used for the mach wire rod of electric spark.In the case, have technical problem to be solved as follows: when there is certain when fracture in wire rod, wire rod must be automatically again the oneself connect so that electric discharge machine processing can continue and without any need for artificial intervention.
Reason is used for the mach wire rod of electric spark and must have any memory for this reason, and this memory may cause one originally once on a reel or the end of wire rod of a wire rod among volume is inverted covers itself and form a winding.
Thereby after the wire rod fracture, the end of wire rod must keep its track, and the Buddhist wire rod of walking back and forth never had any fracture.
So far, this problem all be rely on wire rod heat treatment and/or before twining stretching way solve.The invention enables and may exempt these treating methods, and can avoid using reel, and the various restrictions that are associated with its use.In fact, use reel to limit the wire rod quantity (standard weights 5 kilogram) of each wire rod, although this quantity has the trend of increase around volume.On the other hand, surpass 15 kilograms, just must be installed in reel on the one motor-driven uncoil-stand, so both can strengthen cost, cause again and the inconsistent vibration of the mach precision of electric spark.
At last, the problem that reuses these reels that are made of plastics becomes serious day by day.The use of a reel can not surpass 3-4 time at most, because it stands very big stress during twining, this stress is tending towards making it to disintegrate, and it will definitely damage subsequently.
The method that is encapsulated in the bucket according to the present invention provides a kind of good especially way that addresses these problems, that is:
* can use the bigger bucket of per unit weight and not need a motor-driven uncoil-stand;
* bucket can repeated application many times because packaging operation can not cause significant mechanical stress;
* bucket can resemble cardboard and the such material that reuses of steel constitutes by some.
Fig. 1 shows a kind of pre-stretching cross sectional representation of the equipment of stretching wire rod 1 in advance that remains that is used for, and this equipment comprises successively:
* one is used for emitting from rolling wheel the device 4 of prestretching straight line material 1, and is used to adjust " slack adjuster " 5 how it emits,
* 4 plane series that 7 stretching running rollers are arranged respectively, the orientation of second series becomes 90 ° with first series, and the orientation of the 3rd series takes over 45 °, and the orientation that Quaternary system is listed as is taken back 45 °, has only the 3rd series 6 to be illustrated among Fig. 1,
* the capstan winch 7 of a major diameter (1,000 millimeter), so that provide a straight wire rod at the end that goes out of capstan winch,
* two pairs of trough of belt cylindrical shape running rollers that are contained in above the same rotation platen 8, it clamps wire rod, gives reaction torque by the rotation of this platen,
* a cylinder 16 is driven and is carried out and platen 8 same rotatablely moving, and prestretching straight line material 2 is guided enters in the bucket 3, thereby form one of prestretching straight line material around rolling up 15,
* one barrel 3 and be used to fall to putting the device 9 of bucket, the mode that falls to putting is, the bottom of cylinder 16 always just in time be in be formed on the bucket the inside prestretching straight line material around the top of volume 15, its diameter has been determined this internal diameter around volume 15 basically.
Fig. 2 shows that with cross section prestretching straight line material is to prevent that during transportation any of each wire rod solenoid tangles around the final packaged type of volume 15.
One plastics ring 10 is by means of buckle 11, an elastic straps 12, and one is anchored on the rigidity straight-bar 13 of bucket 3 bottoms by an annulus 14 and keeps pressing top in around volume 15.
Buckle 11, elastic straps 12 and rigidity straight-bar 13 be provided with can make wire rod before use transportation and be held in place between the storage life.Between the operating period, they will be laid down at wire rod, so that each solenoid is from withdrawing from around volume.
Another theme of the present invention as illustrated in fig. 1 and 2, is the preparation of above-mentioned prestretching straight line material 2 encapsulation, wherein, is a kind of pre-stretching metal wire rod of acquisition in a cylindrical shape bucket 3 the insides,
A) remain pre-stretching wire rod 1 through a series of stretching running rollers 6, can keep the major diameter capstan winch of wire rod glacing flatness in advance to drag by one simultaneously;
B) wire rod is arranged within two orthogonal planes and is driven and stands to reverse during the non-motor-driven running roller 8 that rotates around wire rod at it subsequently through two pairs;
C) this wire rod 2 has cylinder 16 guidings that rotatablely move equally by one, is laid in the bottom of bucket 3 with a solenoid form;
D) this bucket is 3 along with it is descended by filling, so that the gap of the Free Surface of wire rod between bottom this cylinder remains unchanged.
Therefore the applicant makes a kind of known technical process be applicable to preparation according to prestretching straight line material of the present invention.
At metal wire rod is under the situation about being made by brass, the invention enables to guarantee the sealed storage of prestretching straight line material around volume 15, can avoid in moist atmosphere like this, or in the risk that has wire rod generation stress corrosion under the situation of ammonia (" air-dry crackle ").Other ways also can be used for further reducing this risk: add some Wet removing bags, can consolidate the product of ammonia, perhaps be adsorbed on the protectiveness product on the wire surface, and the adiabatic apparatus of bucket, the latter can reduce the impact of environment temperature change.
Some other theme of the present invention comprises: use and directly wire rod is fed to machining apparatus according to prestretching straight line material method for packing of the present invention, particularly lathe and turning machine perhaps feed to the cold forging lathe; And use feeds to the electric discharge machine process equipment to wire rod according to prestretching straight line material method for packing of the present invention.
The present invention also comprises the method for packing that uses any prestretching straight line material, and no matter wire rod is to make by steel or by the non-ferrous alloy beyond the copper material, with directly wire rod feeding machining apparatus, particularly lathe and turning equipment, perhaps feeding cold forging lathe.In fact, the applicant can confirm, as mentioned above, adopts such as the such basic principle that each Albatra metal-found out of brass, can be used for the steel wire rod.
Prepare a prestretching straight line material 2 around the volume 15.This wire rod has following characteristic:
Component: brass with 36%Zn and 3%Pb
Diameter: 1.825 millimeters
Mechanical strength: 620 MPas
Employing is shown in the equipment of Fig. 1.
4 plane series 6 that 7 stretching running rollers are arranged respectively are as stretcher, and relative orientation each other is: (+90 °/-45 ° /+45 °).
The feed speed of wire rod is 250 meters/minute, and the rotary speed of a pair of running roller 8 and cylinder 16 is 130 commentaries on classics/per minutes.
This wire rod is encapsulated among suitable 250 kilograms of buckets 3, as shown in Figure 2.
The diameter of this barrel must be restricted to the curvature that can surpass its elastic limit even as big as not making wire rod.Generally, this diameter under the situation of a kind of minor diameter (＜1 millimeter) wire rod, is 510 millimeters; Under the situation of a kind of intermediate diameters wire rod (diameter is 1.8 millimeters levels), it is 580 millimeters; And be under the situation of 3 millimeters level wire rods at a kind of diameter, be 620 millimeters.
The prestretching straight line material 2 that obtains (R) is tested on the stretcher leveler at one " TORNOS ", uses and do not use the stretcher that has a rotating frame.
When not using rotating frame, obtained bar 4 meters long, that have every meter 4 millimeters amounts of deflection.This deflection value approximately with one have on the rotating frame of each running roller carry out stretching operation for wire rod with same component and geometrical property after, the deflection value that obtains according to a kind of bar that method B produced is the same substantially.
Use after the rotating frame, obtained 4 meters long, to have maximum immunity value be 0.5 millimeter every meter bar, this value is approximately corresponding to the straight level of each bar that obtains according to method A.
Every meter amount of deflection is littler, and the vibration that occurs during bar rotates at a high speed is fewer, and mach precision is higher, and perhaps, selectively, machined speed is higher.
Generally, use the bar with about 4 millimeters/meter amount of deflection, the precision that can reach is 10 microns at present, and uses one to have 0.5 millimeter/meter or fewer bar of amount of deflection, and accessible precision is 5 micron orders.
Equally, during machined speed under considering the constant situation of precision level, if a bar with 4 millimeters/meter amounts of deflection with one have 1 millimeter or more the bar of small deflection replace, the growth of productivity ratio approximately is 15%.
The applicant did other a large amount of tests, changed component and how much or the mechanical property of copper alloy, and the geometry of process for machining and processing work.
Specifically, the applicant notices, when the big length of machined (general 40 millimeters) workpiece, can avoid original according to prestretching straight line material of the present invention for eliminating " brass memory " needed heat treatment around volume, and be 0.05 millimeter workpiece not making under the heat treated situation to obtain to have amount of deflection, franchise is 0.07 millimeter.
The applicant also once used according to prestretching straight line material of the present invention and not only used machined, and made workpiece with cold forging.At this, the applicant notices once more, because the residual deformation that is caused during the coiling before being placed in bucket, among general from 30 to 50 millimeters big length workpiece, the amount of deflection problem still occurs, and can cause scrapping of final products, although re-adjustments straightening device repeatedly.
Equally in the case, prestretching straight line material in this example can reduce the size of amount of deflection significantly.
A kind of representative instance of the workpiece that is obtained by cold forging from the geometry franchise angle of strictness, is the anode of alkaline battery.
Also the wire rod with different-diameter has been done test (brass wire with 3 and 6 mm dias has been done test), also the wire rod with different brackets mechanical strength has been done test: " firmly " and " crisp " alloy shows successfully within the pointed boundary of claim 1 after tested such as leaded bronze (Cu-Sn-Pb) or leaded nickel silver (Cu-Zn-Ni-Mn-Pb).
These boundaries come from such needs: for the bar that rotates because of the machined purpose obtains amount of deflection less than 5 millimeters/meter.
If use too thick and/or too tough wire rod, they will cause the residual deflection of bar greater than this boundary of 5 millimeters/meter.
Embodiment 2
Prepare a prestretching straight line material 2 around volume 15, be used for electric discharge machine processing.This wire rod is equivalent to the wire rod described in the example of European patent 0526361-A1, has following various characteristics:
Component: Cu-Zn37
Diameter: 0.25 millimeter
Mechanical strength: 910 MPas
This according to wire rod of the present invention on a spark-erosion machine tool through tested person, contrast with a standard wire.Before winding, standard wire stands certain heat treatment or certain machinery or stretching processing.
According to the performance of wire rod in the bucket of the present invention be equal to according on the reel of prior art through the performance of the wire rod of Overheating Treatment or mechanical stretching processing.
The problem that the invention solves various types of users and run on various types of equipment, these equipment are: turning machine and spark-erosion machine tool, and cold forging lathe.
At each in this case, improvements relate to the speed of production of the workpiece that is used for all purposes, such as electrical connection arrangement, and thereby relate to productivity ratio, the final fine quality that perhaps relates to these workpiece is reduced to and produces the required investment of workpiece, perhaps certain combination of these advantages.
Under the situation of turning, the present invention has eliminated some shortcomings that are associated with known each method that originally was denoted as A and B, is a kind of comprehensive of them.
* the same with method A, the client who carries out turning needn't worry about for stretching bar, and is same, carries out some remaining solenoid occurring when the mach client of electric spark also needn't be ruptured for the contingency wire rod and worries about.
* simultaneously, with the same among the method B, the wire cut merchant needn't use jumbo.In fact, employed pre-stretching equipment is easy to can not reduce in place, the end adding of a drawing production line productivity levels of drawing, perhaps increases production cost, and secondly, the required investment of these equipment is less than various industrial seven-roll Abramsen machines far away.
Generally speaking, though for wire rod producer, pre-stretching equipment remains essential, on the other hand, for lathe operation person, no longer must join a seven-roll Abramsen machine for each chassis bed, and this point has constituted a sizable saving.
Thereby stretching operation can be decomposed into two operations:
One pre-stretching operation, producer finishes by wire rod.This operation to be carrying out at a high speed (generally from 4 to 9 meter per seconds), and for to guarantee that the required high draw rate of high production rate adapts.
The stretching operation of one finishing is selectable, is finished by the user.The stretching operation of this finishing requires to be careful, and carries out (generally from 0.1 to 0.5 meter per second) under low speed.It is stretching to be engaged in high-quality with a kind of inexpensive equipment.In the case, low speed can not constitute obstacle, because stretchingly carry out simultaneously, and unique restriction operation occurs in the machined stage.In general, as top emphasizing, requisite is that it is cheap that stretching equipment is wanted, and is equipped with such equipment because lathe operation person is necessary for his each lathe.
Decompose by this way according to stretching operation of the present invention, the two just all can be optimized quality and productivity ratio, because the both sides that participate in, wire rod producer and user are allowed to be engaged in production with they characteristic velocities separately.
In some other advantage of the present invention, it is worthy of note:
* adopt to possess the very possibility of the wire rod of high mechanical properties, this wire rod is more suitable in turning than " softer " wire rod, because smear metal tiny (generally be 0.05 millimeter, but not 0.5 millimeter) and removing easily.
* approach to eliminate the risk that fracture during wire rod is stretching, occurs,, and in prior art, say fifty-fifty that the wire rod of once observing per 250 kilograms of buckets once ruptures because no longer include any plastic deformation of wire rod.
* the significantly reduced vibration that is associated with the amount of deflection of reduced levels, this also can cause a lower tool failure rate: adopt the present invention, the consumption of cutter drops to per 5000 kilograms of wire rods one to cutter cutter from per 2000 kilograms of wire rods one.
* with the wire rod feeding machined of coming from bucket or the possibility of former, not resembling in the prior art, these barrels are arranged on the bottom of each lathe, leave these lathes somewhere and be arranged on, such as being a storage place, the sheath pipe can be guided this wire rod therefrom and be led to machining apparatus, because also know, a prestretching straight line material can pass through a root sheath pipe.
Such design can reduce the required space of each lathe, and can reduce moving and loading and unloading of each barrel, thereby has reduced the risk that has an accident or collide.
* in bucket, encapsulate the possibility of " firmly " or " crisp " property alloy, these alloys are not suitable for being encapsulated among the bucket, or because they have during stretching during very high yield strength and the coiling before being placed to bucket the inside and after debatching, need sizable strength to reach elastic range, or because they have extremely narrow plastic deformation scope, so that even such as once reeling or the allowable elongation of once stretching limited plastic deformation when just being enough to surpass its fracture partly, thereby cause the repeatedly fracture of wire rod.
Thereby, be that prestretching straight line material that the alloy of Cu-Sn-Pb (" leaded bronze ") and Cu-Zn-Ni-Mn-Pb (" leaded nickel silver ") is made can be encapsulated among the bucket by a kind of component.
Under the mach situation of electric spark, the various advantages that the present invention presents also are significant in following each side:
* eliminated heat treatment or mechanical stretching processing,
* per unit weight may be bigger, thereby the automation performance also may be higher, and the wire rod weight of every volume generally is 5 kilograms, and every barrel of wire rod weight is unrestricted.
* having eliminated needs reel motor-driven uncoil-stand, that must damage after the coiling of limited number of times, and each barrel can be reused many times.
At last, no matter how to use according to prestretching straight line material of the present invention, the applicant notices, according to method for packing of the present invention, under same bucket size, with respect to the method in traditional bucket that wire rod is packed into, make wire rod quantity double (with compare according to 250 kilograms of prior art, be 500 kilograms according to the present invention).This be because, in traditional method for packing, each solenoid must be " inflation " comparatively speaking so that reduce the problem of tangling during debatching, and under situation of the present invention, all solenoid all be very be close to closely knit stratification.
