Description
Technical field
This patent belongs to the manufacturing technology field of welding material, belongs to the B23k35/40 of IPC code, still belongs to by rolling
The shaping jig technical field of the metal drawing in the section that post, ball or like parts are limited, belongs to the B21C3/ of IPC code
08, more particularly to active roller die and passive roller die.
Background technology
At present, the key link that flux-cored wire tube reducing is flux-cored wire production is made by the way of drawing, specifically
It is that flux-cored wire is drawn by the wire drawing hub (or referred to as wire drawing tank, reel) of wire drawing machine in fact, multi-turn flux-cored wire is wrapped in volume
On cylinder, to form friction self-locking, flux-cored wire receives the frictional force between reel and overcome to realize by when wire drawing die
The frictional force of tube reducing resistance between wire drawing die.In in this way, due in drawing process, it is impossible to ensure that medicine core is welded
The material substantially uniformity of silk, and transmission process also not necessarily entirely accurate, so when wire drawing machine is multi-joint wire drawing machine,
Need to set kink between each reel, or tension coordinating roller, to compensate incomplete of speed between each reel
With problem, and by speed difference reflection into control system, run each reel of wire drawing machine by control system and be attributed to balance.
Under this pattern, it is necessary to which motor has the larger margin of power, so that the larger reel of rapidly adjustment rotary inertia causes respectively
Speed coordination between individual reel.So, in drawing tube reducing, in addition to overcoming the resistance that tube reducing is deformed the need for basic, also need
Overcome frictional resistance of the flux-cored wire in wire drawing die, and flux-cored wire of the multiple-turns wound on reel on reel upwards
The resistance creeped, along with for the work(for overcoming each rotary part is larger on wire drawing machine rotary inertia to carry out speed governing and reserving
Rate surplus, the general power that this three has resulted in equipment rises, and manufacturing cost rises, and energy resource consumption is huge during operation.
Moreover, such as in existing flux-cored wire processing, the roller die of use is generally the roller die of two rollers, and 2007-10-17 is disclosed
" wire-drawing frame " application publication number be CN101053879A, and " roller die " Authorization Notice No. disclosed in 2012.07.04 be CN
202290813 U.Although this roller die saves a part of frictional resistance than common wire drawing die (stent) drawing.But by
All it is two rolling systems in these roller dies, two roller rolling modes have problems with：
1st, as shown in figure 1, what flux-cored wire mainly received during two rolling systems is the power deformed up and down, so substantially existing
Flux-cored wire is flattened on the vertical line direction of two roll axis, so being first to be rolled into ellipse, roll is then converted 90 °, then will
Oval major axis becomes the short axle of next step, and original short axle becomes the major axis of next step.So this tube reducing process is to hand over
That replaces is deformed into the mutually perpendicular ellipse of major axis, the complete flux-cored wire of last tube reducing nor positive round.So for being processed into
Product circularity is required for higher flux-cored wire, finally still to need to be configured to flux-cored wire by one of fixing mould
It is circular.For example in the apllied publication number CN1590009A of Japanese kobe steel " method for being used to manufacture seamed cored wire "
Power 2 also simply refer to " from tubulose shape welding wire to before with product diameter close to diameter wires welding wire stretching all
Carried out by roller mould, then, the stretching of finishing welding wire carried out by casement in last welding wire draw stage ", it is not to lead to yet
Cross roller die and realize whole welding wire drawing process.So in the two patents made by four pairs of roller-die combinations together
With staggering 90 ° per between adjacent two Dui.This is also for being avoided in single tube reducing the oval mistake that reducing rate is excessive, causes
It is flat, also to spend larger active force to correct the ellipse that this is more flat when next tube reducing, be allowed to become round, Ran Houzai
Carry out tube reducing.The additional forces brought also for the ellipse reduced in each deformation process are arranged so as to, tube reducing is reduced
During resistance.
2nd, two rolling systems can not form a completely enclosed space, between topping roll and bottom roll (left and right roll)
The side of the groove rolled can also leave space, and this space can clearly be seen in CN202290813U accompanying drawing
Arrive, the deformation of flux-cored wire, which leaves, when may be to tube reducing can outwards flow the space of extension, two ears are formed on section
Portion (as shown in Figure 2).Because being usually alternately 90 ° of setting roller dies using Concerning Pipe-reducing With Roll Type Die, and the two ears are next time
In rolling, the reinforcement ridge that confrontation is deformed next time can be formed, so as to increase the deformation force of flux-cored wire deformation.Likewise, using
Existing two common rolling framves carry out actively rolling and also there is a problem in that, so being also accomplished by the rolling of more sortie
Tube reducing process can be completed, such as authorized announcement date 2012.06.20 Authorization Notice No. welds for CN202278316U medicine core
Silk forming machine, employs up to 18-22 groups horizontal roll and 17-21 groups vertical roller carries out tube reducing, and so many roll stacks are entered
Row adjustment, is exactly a very complicated thing.
3rd, in the roll axis plane by two rolls, what each roll and flux-cored wire were contacted be together with camber line,
The linear velocity of each point of this road camber line topping roll is different, it is assumed that the radius of roll is R, and the radius of the groove of roll is
Gap between r, two rolls is d, and linear velocity is ω, then the maximum point of linear velocity is the edge of camber line, and its radius is R,
Linear velocity is r ω, and the minimum point of linear velocity is the center of camber line, and its radius is R+d/2-r, and its linear velocity is (R+d/2-
R) ω, for any drawing tube reducing process, the gap being all desirable between d/2 and r is the bigger the better, such tube reducing effect
Become apparent from, so the difference of linear velocity is actually also bigger, and the speed of each point on this camber line of flux-cored wire is system
One, then the linear velocity point inconsistent with linear velocity on flux-cored wire is just certainly existed on roll.So result in
The part of flux-cored wire and the part of roll there occurs Relative friction, on the one hand add the resistance of tube reducing, on the one hand also grind
Flux-cored wire surface is damaged.

The side plate of roll stand is connected by tightening supporting part 29, a pair of positioning boss passive roll stand frame with each driving rollers frame or each
Two parallel medial surface laminatings of side plate.
The tightening being connected with a base supporting part is respectively provided between driving rollers frame and each pair side plate of passive roll stand frame,
Tightening support zone is in the one end of block side plate of the afterbody of two blocks of side plates, i.e., two away from driving rollers or passive roll, tightening support
A holding screw 36 is threaded with portion, the afterbody of holding screw is against on base, due to holding screw direction perpendicular to
Base, and it is the one end of side plate away from driving rollers and passive roll to install the position of holding screw, so holding screw pair
The direction of driving rollers frame and passive roll stand frame tightening support does not pass through alignment pin.
Due to the position of driving rollers frame and the pin joint of positioning disk be in the root of the biside plate of driving rollers frame, so

The operating principle of the present embodiment is：
First by floor installation on the table top of wire drawing machine, each holding screw is then adjusted so that four roll mandrels
Axis is in the same plane, and the plane is perpendicular to the traffic direction of flux-cored wire.Particularly, due to roll mandrel be with
What driving rollers frame, passive roll stand frame were swung around alignment pin together, so in the case where the accuracy of manufacture can ensure, only
The bottom surface of driving rollers frame and the afterbody of passive roll stand frame --- the one side that holding screw stretches out is consistent with the distance of base,
Ensure that four roll mandrels are all located at this plane perpendicular to flux-cored wire traffic direction.And the axis of four roll mandrels
It is whether parallel, then it is to be determined via two side plates of the alignment pin on positioning disk, driving rollers frame or passive roll stand frame
, as long as the through hole of positioning boss, the manufacture of alignment pin and side plate and assembly precision are sufficiently high on positioning disk, it is possible to protect
Four roll mandrels of card are coplanar or are respectively parallel to this plane perpendicular to flux-cored wire traffic direction.Adjust in this way
The aperture of whole roller die, is easy to find a measuring basis whether being adjusted in place, positioning is convenient, and positioning precision is high.
And in roll stacks in the prior art, such as " roller die " Authorization Notice No. disclosed in 2012.07.04 is CN
In 202290813 U, multiple rows of (multipair) roller die is worn together by bolt, bolt is only responsible for fastening, not
Be responsible for positioning, centre does not have any accurate location measure, the border circular areas that the groove on each pair roller die is formed without
Method ensure conllinear and common line completely be wire drawing machine it is tangential on.So, as shown in figure 11, worn in multipair roller
The path that capable flux-cored wire is walked is exactly a snakelike path, and in drawing processing is carried out, flux-cored wire is in each roller
The larger occasion of this active force between mould is it cannot be guaranteed that if linear running, be unfavorable for ensureing the straight line of flux-cored wire in itself
Degree, Tu11Zhong, the circle and rectangle of dotted line represent to carry out flux-cored wire on the roller of tube reducing, in order to each in the obvious figure that shows
The rigging error between roller is arranged, is also that the technique of painting for employing exaggeration represents the dislocation of each row's roller in figure.
Moreover, being to ensure using the roller die (such as the CN101053879A " wire-drawing frame " of Kobe Steel, Ltd) of eccentric shaft
Aperture meets the requirements, and whether the die hole formed as roll groove completely placed in the middle, or two rolls center
Whether line is vertical with the theoretical traffic direction of flux-cored wire, and that can not ensure.If multiple rows of roller die is used in series, then
Everybody can not see the circular whether completely conllinear of the inside, even if there is location measure to be between ensure that the framework of every row's roller die
Mutually it is pinpoint, but often arrange in two rolls position specifically adjustment where, this is also the presence of parameter.Because,
Such as Figure 12 is unlikely to be two rollers and is in most by taking two edger rolls (axis of roller is vertical) as an example when due to working condition
Near state, so for the roller die using eccentric shaft, it is assumed that the offset per eccentric shaft is L, first band eccentric shaft
Spacing between one end side axle portion of portion's support shaft and second one end side axle portion with eccentric axial portion support shaft is D0, two rollers
Centre distance is D, this D0, and D and two L-shaped is into the double-crank mechanism of four bars, and this double-crank mechanism may be adjusted to
Any position, even if center and the theoretical traffic direction out of plumb of flux-cored wire of two rollers, are also that can adjust to obtain completely
, be just one section of side axle portion that less solid line circle is represented in Figure 12, the circle expression of dotted line is if roller and side axle portion are same
Position and outline during the heart, tangent two of solid line justify the position that the actual capabilities of the roll represented are adjusted to.So, such as
Shown in Figure 13, the circle of dotted line represents roll and position during concentric side axle portion and outline, tangent two of solid line in fig. 13
The position that the actual capabilities for the roll that individual circle is represented are adjusted to.It can be seen that being essence between the framework of every row's roller die
It is determined that when position, if the position of die hole that is formed between two roller dies in each row it cannot be guaranteed that if unified,
It is that there is the problem of serpentine path is in path of the flux-cored wire between multipair rod.So also can using the roller die of eccentric shaft
Exist because the problem of circle is not conllinear caused by adjustment eccentric shaft.
Active roller die in the present embodiment is due to its tube reducing efficiency high, and four Roller. redress are convenient, as long as ensureing tight
The one side for determining screw stretching is consistent with the distance of base, it is possible to ensure that four roll mandrels are all located at this perpendicular to flux-cored wire
The plane of traffic direction, in the absence of the die hole between each row in existing multiple rows of roller die it is not conllinear the problem of, so as to improve
The tube reducing quality of flux-cored wire.
After active/passive roll stand frame is adjusted in place, roll frame torr angle 6 is fixed on base, and per a pair roller
The afterbody of active/passive roll stand frame is clamped at frame torr angle, so it is prevented that because driving rollers frame or passive roll stand frame length
It is larger, rely solely on the alignment pin positioned at active/passive roll stand frame root and be not enough to that active/passive roll stand frame tail is completely secured
Portion relatively stablizes, so clamping the afterbody of active/passive roll stand frame by roll frame torr angle, prevents active/passive roll stand frame
Afterbody is shaken, so as to influence roll to the crudy of flux-cored wire.
When being processed to flux-cored wire, power by electric-motor drive to single-input double-output reduction box, by reduction box
Driving gear shaft is transferred to through Hooks coupling universal coupling, power is transferred to driven gear by the teeth portion of driving gear shaft, due to passive tooth
Wheel is directly to be fixed by screw and driving rollers, so power is transferred directly to driving rollers by driven gear, is actively rolled
Roller carries out tube reducing to flux-cored wire, and the flux-cored wire drive during passive roll is run is rotated, from two other sides
To the deformation direction for constraining welding wire.So as to improve tube reducing efficiency during processing flux-cored wire.

The operating principle of the present embodiment is：
First by floor installation on the table top of wire drawing machine, each holding screw is then adjusted so that four roll mandrels
Axis is in the same plane, and the plane is perpendicular to the traffic direction of flux-cored wire.Particularly, due to roll mandrel be with
What passive roll stand frame was swung around alignment pin together, so in the case where the accuracy of manufacture can ensure, as long as handle passively rolls
The one side that the bottom surface of the afterbody of roll stand --- holding screw stretches out is consistent with the distance of base, it is possible to ensure four roll mandrels all
Positioned at this perpendicular to flux-cored wire traffic direction plane.Then it is via fixed and whether the axis of four roll mandrels is parallel
Two side plates of alignment pin, passive roll stand frame on the disk of position come determined, as long as the through hole of positioning boss on positioning disk, fixed
Position bearing pin and the manufacture of side plate and assembly precision are sufficiently high, it is possible to ensure that four roll mandrels are coplanar or are respectively parallel to this
Perpendicular to the plane of flux-cored wire traffic direction.The aperture of roller die is adjusted in this way, is easy to find whether one adjust
Measuring basis in place, positioning is convenient, and positioning precision is high.
And in roll stacks in the prior art, such as " roller die " Authorization Notice No. disclosed in 2012.07.04 is CN
In 202290813 U, multiple rows of (multipair) roller die is worn together by bolt, bolt is only responsible for fastening, not
Be responsible for positioning, centre does not have any accurate location measure, the border circular areas that the groove on each pair roller die is formed without
Method ensure conllinear and common line completely be wire drawing machine it is tangential on.So, as shown in figure 11, worn in multipair roller
The path that capable flux-cored wire is walked is exactly a snakelike path, and in drawing processing is carried out, flux-cored wire is in each roller
The larger occasion of this active force between mould is it cannot be guaranteed that if linear running, be unfavorable for ensureing the straight line of flux-cored wire in itself
Degree, Tu11Zhong, the circle and rectangle of dotted line represent to carry out flux-cored wire on the roller of tube reducing, in order to each in the obvious figure that shows
The rigging error between roller is arranged, is also that the technique of painting for employing exaggeration represents the dislocation of each row's roller in figure.
Moreover, being to ensure using the roller die (such as the CN101053879A " wire-drawing frame " of Kobe Steel, Ltd) of eccentric shaft
Aperture meets the requirements, and whether the circle formed as roll groove is completely placed in the middle, if multiple rows of roller die is used in series, that
Everybody can not see the circular whether completely conllinear of the inside, even if between having the framework that location measure ensure that every row's roller die
Be mutually it is pinpoint, but often arrange in two rolls position specifically adjustment where, this is also the presence of parameter.Cause
For such as Figure 12 is unlikely to be at two rollers by taking two edger rolls (axis of roller is vertical) as an example when due to working condition
In nearest state, so for the roller die using eccentric shaft, it is assumed that the offset per eccentric shaft is L, the first band-offset
Spacing between one end side axle portion of heart axle portion support shaft and second one end side axle portion with eccentric axial portion support shaft is D0, two
The centre distance of roller is D, this D0, and D and two L-shaped is into the double-crank mechanism of four bars, and this double-crank mechanism can adjust
It is whole to arrive any position, even if center and the theoretical traffic direction out of plumb of flux-cored wire of two rollers, are also that can adjust completely
Obtain, be just one section of side axle portion that less circle is represented in Figure 12, the circle expression of dotted line is if roller and side axle portion are same
Position and outline during the heart, tangent two of solid line justify the position that the actual capabilities of the roll represented are adjusted to.So, such as
Shown in Figure 13, the circle of dotted line represents roll and position during concentric side axle portion and outline, tangent two of solid line in fig. 13
The position that the actual capabilities for the roll that individual circle is represented are adjusted to.It can be seen that being essence between the framework of every row's roller die
It is determined that when position, if the position of die hole that is formed between two roller dies in each row it cannot be guaranteed that if unified,
It is that there is the problem of serpentine path is in path of the flux-cored wire between multipair rod.So also can using the roller die of eccentric shaft
Exist because the problem of circle is not conllinear caused by adjustment eccentric shaft.
Passive roller die in the present embodiment is due to its tube reducing efficiency high, and four Roller. redress are convenient, as long as ensureing tight
The one side for determining screw stretching is consistent with the distance of base, it is possible to ensure that four roll mandrels are all located at this perpendicular to flux-cored wire
The plane of traffic direction, in the absence of the die hole between each row in existing multiple rows of roller die it is not conllinear the problem of, so as to improve
The tube reducing quality of flux-cored wire.
After passive roll stand frame is adjusted in place, roll frame torr angle 6 is fixed on base, and every a pair of roll stand frames support angle
The afterbody of passive roll stand frame is clamped, so it is prevented that because passive roll stand frame length is larger, relying solely on positioned at dynamic roll
The alignment pin of frame root is not enough to be completely secured passive roll stand frame afterbody and relatively stablized, thus clamped by roll frame torr angle by
The afterbody of dynamic roll stand frame, prevents the afterbody of passive roll stand frame from shaking, so as to influence roll to the crudy of flux-cored wire.
When being processed to flux-cored wire, flux-cored wire is driven by drawing block and advanced, and during advance, runs into four
The die hole that the groove of individual passive roll is formed carries out tube reducing, and the flux-cored wire drive during passive roll is run is revolved
Turn, the deformation direction of welding wire is constrained jointly from 4 directions, so that tube reducing efficiency when improving processing flux-cored wire.
