Description
Technical field
This patent belongs to the manufacturing technology field of welding material, the B23k35/40 that belongs to IPC classification number, the shaping jig technical field that also belongs to the metal drawing in the cross section being limited by roller, ball or like parts, belongs to the B21C3/08 of IPC classification number, particularly relates to a kind of flux-cored wire forming machine.
Background technology
At present, it is the key link that flux-cored wire is produced that the mode of employing drawing makes flux-cored wire tube reducing, wire drawing hub (or being referred to as wire drawing tank, reel) the traction flux-cored wire by wire drawing machine particularly, multi-turn flux-cored wire is wrapped on reel, to form friction self-locking, flux-cored wire receive and reel between frictional force realize tube reducing resistance when overcoming by the wire drawing die frictional force and between wire drawing die.In adopting in this way, in drawing process, the material that can not guarantee flux-cored wire is completely even, and also entirely accurate not necessarily of transmission process, so when wire drawing machine is multi-joint wire drawing machine, need to kink be set between each reel, or tension coordinating roller, to compensate the speed Incomplete matching problem between each reel, and speed difference is reflected in control system, by control system, makes each reel operation of wire drawing machine be attributed to balance.Under this pattern, just need motor to have the larger margin of power, to adjust rapidly the reel that rotary inertia is larger, make the speed coordination between each reel.So, in drawing tube reducing, except the basic resistance that need to overcome tube reducing distortion, also need to overcome the frictional resistance of flux-cored wire in wire drawing die, and multi-turn is wrapped in the resistance that the flux-cored wire on reel is upwards creeped on reel, add in order to overcome that each rotary part on wire drawing machine carries out speed governing compared with large rotary inertia and the power headroom that reserves, this three has just caused the general power of equipment to rise, manufacturing cost rises, and energy resource consumption is huge during operation.
And, in existing flux-cored wire processing, the roller die adopting mostly is the roller die of two rollers, and for example 2007-10-17 disclosed " wire-drawing frame " application publication number is CN101053879A, and 2012.07.04 disclosed " roller die " Granted publication number is CN202290813U.Although this roller die has been saved a part of frictional resistance than common wire drawing die (fixed die) drawing.But because these roller dies are all two rolling systems, two roller rolling modes have following problem:
1, as shown in Figure 1, what in the two roller operations of rolling, flux-cored wire was mainly subject to is the power of being out of shape up and down, so flux-cored wire is flattened in the vertical line direction of two roll axis in fact, so be to be first rolled into ellipse, then 90 ° of roll conversion, oval major axis is become to next step minor axis, minor axis has originally become next step major axis again.So this tube reducing process be alternately be deformed into the mutually perpendicular ruined institute of major axis, the last complete flux-cored wire of tube reducing neither just justified.So for the flux-cored wire of having relatively high expectations for processed finished products circularity, finally still will need to make flux-cored wire be configured as circle by one fixed mould.For example, power 2 in the publication number CN1590009A that Japanese kobe steel is applied for " for the manufacture of the method for seamed cored wire " has also just been mentioned " welding wire being shaped from tubulose is all undertaken by roller mould to the welding wire stretching that approaches diameter welding wire having product diameter; then; in the end welding wire draw stage is carried out the stretching of finishing welding wire by casement ", is not also to realize whole welding wire drawing process by roller die.So be all to use by four pairs of roller-die combinations together, between every adjacent two couple, stagger 90 ° in these two patents.This is also excessive for fear of reducing rate in single tube reducing, and the ellipse causing is excessively flat, also will spend larger active force to correct this more flat ellipse in the time of next tube reducing, makes it to become circle, and then carries out tube reducing.Layout is also the additional forces that the ellipse in order to reduce in each deformation process brings like this, reduces the resistance in tube reducing process.
2, two rolling systems can not form a complete totally enclosed space, between topping roll and bottom roll (left and right roll), in the side of the groove being rolled, also can leave space, this space can be clearly seen that in the accompanying drawing of CN202290813U, in the time of may giving tube reducing, the deformation of flux-cored wire stays on the ， cross section, space of extending of can outwards flowing and forms Er Ge ear (as shown in Figure 2).Because adopting Concerning Pipe-reducing With Roll Type Die is generally to replace 90 ° roller die is set, Er Zheliangge ear, in upper rolling once, can form the reinforcement ridge that antagonism is out of shape next time, thereby increases the deformation force of flux-cored wire distortion.Same, use existing two common rolling framves to carry out initiatively rolling and also can have such problem, so also just need the rolling of more sortie can complete tube reducing process, for example the Granted publication of Granted publication day 2012.06.20 number is the flux-cored wire forming machine of CN202278316U, adopted nearly 18-22 group horizontal roll and 17-21 group vertical roller to carry out tube reducing, so many roll stacks are adjusted, and have been exactly a very complicated thing.
3, in passing through the roll axis plane of two rolls, the contact of each roll and flux-cored wire be together with camber line, the linear velocity of each point of this road camber line topping roll is different, the radius of supposing roll is R, the radius of the groove of roll is r, gap between two rolls is d, linear velocity is ω, the edge that the point of linear velocity maximum is camber line so, its radius is R, linear velocity is r ω, the center that the point of linear velocity minimum is camber line, its radius is R+d/2-r, its linear velocity is (R+d/2-r) ω, as any drawing tube reducing process, all to wish that the gap between d/2 and r is the bigger the better, tube reducing effect is more obvious like this, so the difference of linear velocity is in fact also just larger, and the speed of each point on this camber line of flux-cored wire is unified, on roll, just certainly existed the inconsistent point of linear velocity on linear velocity and flux-cored wire so.So just caused the part of flux-cored wire and the part of roll that relative friction has occurred, increased on the one hand the resistance of tube reducing, the flux-cored wire surface of also having worn and torn on the one hand.

Embodiment 3:
Refer to Fig. 7 to Figure 10,
A kind of active roller die, comprise at least one pair of passive roll, the rotation of every pair of passive roll is parallel to each other, also include at least one pair of initiatively roll, the rotation of every pair of active roll is parallel to each other, every pair initiatively has at least an active roll by transmission device, to be connected with drive unit or to be directly connected with drive unit in roll, and the rotation of whole initiatively rolls and passive roll is in same plane, and this plane is vertical with flux-cored wire.
Particularly:
Initiatively roll stand frame and passive roll stand frame are installed on positioning disk 23, positioning disk is provided with 4 positioning boss 30, 4 positioning boss are towards the same side of positioning disk and be evenly distributed on same circumference, positioning boss is provided with positioning through hole 32, all the center line of positioning through hole is in the same plane, the traffic direction of this plane and flux-cored wire is vertical, initiatively roll stand frame is installed on mode in positioning through hole by alignment pin 31 and realizes the hinged of the root of roll stand frame initiatively and positioning boss, passive roll stand frame is installed on the hinged of the root of the passive roll stand frame of mode in positioning through hole and positioning boss by alignment pin, on positioning disk, be fixedly installed on base,
Initiatively roll stand frame and passive roll stand frame all have the side plate of pair of parallel, each initiatively the side plate of roll stand frame or each passive roll stand frame by tightening support portion 29, connect, positioning boss initiatively rolls the parallel medial surface of frame or each passive pair of side plates of rolling frame two with each and fits.
Initiatively between roll stand frame and every pair of side plate of passive roll stand frame, all there is a tightening support portion being connected with base, tightening support zone is in the afterbody of two blocks of side plates, two blocks of side plates are away from one end of active roll or passive roll, a holding screw 36 has been threaded on tightening support portion, the afterbody of holding screw is against on base, because the direction of holding screw is perpendicular to base, and the position that holding screw is installed is that side plate is away from one end of active roll and passive roll, so holding screw does not pass through alignment pin to the direction of active roll stand frame and passive roll stand frame tightening support.
Because the position of the pin joint of active roll stand frame and positioning disk is the root at the biside plate of active roll stand frame, so the active roll stand frame on top and roll mandrel above, driving gear shaft, rolling bearing, the weight of the parts such as gland can make initiatively roll stand frame produce the moment of toppling clockwise shown in Fig. 9, in order to prevent that superposed active roll stand frame from toppling, so the top in the tightening support portion of active roll stand frame is provided with a roll stand frame hangers 35, at the top of base, be provided with a spring hangers 33, spring hangers is connected with roll stand frame hangers by spiral stretching spring 34.By the deformation of spiral stretching spring, breaker roll frame hangers produces a pulling force, can hang superposed active roll stand frame.
The operating principle of the present embodiment is:
First by floor installation on the table top of wire drawing machine, then regulate each holding screw, make the axis of four roll mandrels in the same plane, and this plane is perpendicular to the traffic direction of flux-cored wire.Particularly, because roll mandrel is along with active roll stand frame, passive roll stand frame swing around alignment pin together, so in the situation that the accuracy of manufacture can guarantee, as long as the afterbody of initiatively roll stand frame and passive roll stand frame bottom surface---the one side that holding screw stretches out is consistent with the distance of base, just can guarantee that four roll mandrels are all positioned at this perpendicular to the plane of flux-cored wire traffic direction.And whether the axis of four roll mandrels is parallel, by the alignment pin on positioning disk, initiatively two side plates of roll stand frame or passive roll stand frame have decided, as long as manufacture and the assembly precision of through hole, alignment pin and the side plate of positioning boss are enough high on positioning disk, just can guarantee that four roll mandrels are coplanar or be parallel to respectively this perpendicular to the plane of flux-cored wire traffic direction.Adopt the aperture of adjusting in this way roller die, be convenient to the measuring basis that finds one whether to adjust to the right place, location is convenient, and positioning precision is high.
And in roll stacks in the prior art, for example 2012.07.04 disclosed " roller die " Granted publication number is in CN202290813U, many rows (multipair) roller die is worn together by bolt, bolt is just responsible for fastening, be not to be responsible for location, centre does not have any accurate location measure, and the formed border circular areas of groove on every pair of roller die cannot guarantee complete conllinear, and common line is on wire drawing machine tangential.Like this, as shown in figure 11, the path that the flux-cored wire of walking in multipair roller is walked is exactly a snakelike path, and in carrying out drawing processing, the flux-cored wire occasion that this active force is larger between each roller die can not guarantee linear running, be unfavorable for guaranteeing the linearity of flux-cored wire itself, in Figure 11, the circle of dotted line and rectangle represent flux-cored wire to carry out the roller of tube reducing, in order respectively to arrange the rigging error between roller in the figure that significantly shows, in figure, be also to have adopted the technique of painting of exaggerating to represent respectively to arrange the dislocation of roller.
And, adopt the roller die (for example CN101053879A of Kobe Steel, Ltd " wire-drawing frame ") of eccentric shaft just to guarantee that aperture meets the requirements, whether completely placed in the middle as for the formed die hole of roll groove, or whether the line of centres of two rolls is vertical with the theoretical traffic direction of flux-cored wire, that cannot guarantee.If the series connection of many row's roller dies is used, everybody cannot see the whether complete conllinear of circle of the inside so, even if there is location measure can guarantee that between the framework of every row's roller die be pinpoint mutually, but where the position of two rolls in every row specifically adjust to, and this also exists parameter.Because, as Figure 12, take two edger rolls (axis of roller is vertical) is example, in the time of due to duty, can not be that two rollers are in nearest state, so for the roller die of employing eccentric shaft, the offset of supposing every eccentric shaft is L, the first one end side shaft portion with eccentric axial portion bolster and second is D0 with the spacing between one end side shaft portion of eccentric axial portion bolster, the centre distance of two rollers is D, this D0, the double-crank mechanism of D and four bars of two L shaped one-tenth, this double-crank mechanism can be adjusted to any position, even the theoretical traffic direction out of plumb of Liang Gegun center and flux-cored wire, also completely can adjust and obtain, the one section of side shaft portion that is just that in Figure 12, less solid line circle represents, the circle of dotted line represents is if position and the outline of roller when concentric with side shaft portion, the position that the actual capabilities of the roll that two tangent circles of solid line represent are adjusted to.So, as shown in figure 13, position and outline when in Figure 13, the circle expression roll of dotted line is concentric with side shaft portion, the position that the actual capabilities of the rolls that two tangent circles of solid line represent are adjusted to.As can be seen from the figure, when being pinpoint between the framework of every row's roller die, if it is unified that the position of the die hole forming between two roller dies in each row can not guarantee, is also to exist the problem that the path of flux-cored wire between multipair rod is serpentine path.So the circle that adopts the roller die of eccentric shaft also can exist to cause because adjust eccentric shaft is the problem of conllinear not.
Active roller die in the present embodiment is because its tube reducing efficiency is high, and four Roller. redress are convenient, as long as guarantee that the one side that holding screw stretches out is consistent with the distance of base, just can guarantee that four roll mandrels are all positioned at this perpendicular to the plane of flux-cored wire traffic direction, there is not in existing many row's roller dies the not problem of conllinear of the die hole between each row, thereby improved the tube reducing quality of flux-cored wire.
After active/passive roll stand frame is adjusted to the right place, roll stand frame holder angle 6 is fixed on base, and the afterbody of active/passive roll stand frame is clamped at every a pair roller frame holder angle, so just can prevent because active roll stand frame or passive roll stand frame length are larger, only rely on the alignment pin that is positioned at active/passive roll stand frame root to be not enough to guarantee completely that active/passive roll stand frame afterbody is more stable, so rely on roll stand frame holder angle, clamp the afterbody of active/passive roll stand frame, the afterbody that prevents active/passive roll stand frame is shaken, thereby affect the crudy of roll to flux-cored wire.
Flux-cored wire is added to man-hour, power is the reduction box to single-input double-output by electric-motor drive, by reduction box, through Hooks coupling universal coupling, be passed to driving gear shaft, the tooth portion of driving gear shaft by transmission of power to driven gear, because driven gear is directly fixing with active roll by screw, so power is directly passed to initiatively roll by driven gear, initiatively roll carries out tube reducing to flux-cored wire, and passive roll is rotated by operating flux-cored wire drive, from other both direction, retrain the deformation direction of welding wire.Thereby the tube reducing efficiency while having improved processing flux-cored wire.

Passive roll stand frame is installed on positioning disk 23, on positioning disk, be fixedly installed on base 19, positioning disk is provided with 4 positioning boss 30,4 positioning boss are towards the same side of positioning disk and be evenly distributed on same circumference, positioning boss is provided with positioning through hole 32, all the center line of positioning through hole is in the same plane, the traffic direction of this plane and flux-cored wire is vertical, passive roll stand frame is installed on the hinged of the root of the passive roll stand frame of mode in positioning through hole and positioning boss by alignment pin 31
Each passive roll stand frame has the side plate of pair of parallel, and the side plate of each passive roll stand frame connects by tightening support portion 29, and the positioning boss medial surface parallel with two of each passive pair of side plates of rolling frame fitted.
Between every pair of side plate of passive roll stand frame, all there is a tightening support portion 29 being connected with base, tightening support zone is in the afterbody of two blocks of side plates, two blocks of side plates are away from one end of active roll or passive roll, a holding screw 36 has been threaded on tightening support portion, the afterbody of holding screw is against on base, because the direction of holding screw is perpendicular to base, and the position that holding screw is installed is that side plate is away from one end of passive roll, so the direction that holding screw supports passive roll stand frame tightening is not passed through alignment pin.
Because the position of the pin joint of passive roll stand frame and positioning disk is the root at the biside plate of passive roll stand frame, so the passive roll stand frame on top and roll mandrel above, passive tooth wheel shaft, rolling bearing, the weight of the parts such as gland can make passive roll stand frame produce the moment of toppling clockwise shown in Fig. 8, in order to prevent that superposed passive roll stand frame from toppling, so the top in the tightening support portion of passive roll stand frame is provided with a roll stand frame hangers 35, at the top of base, be provided with a spring hangers 33, spring hangers is connected with roll stand frame hangers by spiral stretching spring 34.By the deformation of spiral stretching spring, breaker roll frame hangers produces a pulling force, can hang superposed passive roll stand frame.
The operating principle of the present embodiment is:
First by floor installation on the table top of wire drawing machine, then regulate each holding screw, make the axis of four roll mandrels in the same plane, and this plane is perpendicular to the traffic direction of flux-cored wire.Particularly, because roll mandrel is along with passive roll stand frame swings around alignment pin together, so in the situation that the accuracy of manufacture can guarantee, as long as the bottom surface of the afterbody of passive roll stand frame---the one side that holding screw stretches out is consistent with the distance of base, just can guarantee that four roll mandrels are all positioned at this perpendicular to the plane of flux-cored wire traffic direction.And whether the axis of four roll mandrels is parallel, by two side plates of the alignment pin on positioning disk, passive roll stand frame, to have been decided, as long as manufacture and the assembly precision of through hole, alignment pin and the side plate of positioning boss are enough high on positioning disk, just can guarantee that four roll mandrels are coplanar or be parallel to respectively this perpendicular to the plane of flux-cored wire traffic direction.Adopt the aperture of adjusting in this way roller die, be convenient to the measuring basis that finds one whether to adjust to the right place, location is convenient, and positioning precision is high.
And in roll stacks in the prior art, for example 2012.07.04 disclosed " roller die " Granted publication number is in CN202290813U, many rows (multipair) roller die is worn together by bolt, bolt is just responsible for fastening, be not to be responsible for location, centre does not have any accurate location measure, and the formed border circular areas of groove on every pair of roller die cannot guarantee complete conllinear, and common line is on wire drawing machine tangential.Like this, as shown in figure 11, the path that the flux-cored wire of walking in multipair roller is walked is exactly a snakelike path, and in carrying out drawing processing, the flux-cored wire occasion that this active force is larger between each roller die can not guarantee linear running, be unfavorable for guaranteeing the linearity of flux-cored wire itself, in Figure 11, the circle of dotted line and rectangle represent flux-cored wire to carry out the roller of tube reducing, in order respectively to arrange the rigging error between roller in the figure that significantly shows, in figure, be also to have adopted the technique of painting of exaggerating to represent respectively to arrange the dislocation of roller.
And, adopt the roller die (for example CN101053879A of Kobe Steel, Ltd " wire-drawing frame ") of eccentric shaft just to guarantee that aperture meets the requirements, whether completely placed in the middle as for the formed circle of roll groove, if the series connection of many row's roller dies is used, everybody cannot see the whether complete conllinear of circle of the inside so, even if there is location measure can guarantee that between the framework of every row's roller die be pinpoint mutually, but where the position of two rolls in every row is specifically adjusted to, and this also exists parameter.Because, as Figure 12, take two edger rolls (axis of roller is vertical) is example, in the time of due to duty, can not be that two rollers are in nearest state, so for the roller die of employing eccentric shaft, the offset of supposing every eccentric shaft is L, the first one end side shaft portion with eccentric axial portion bolster and second is D0 with the spacing between one end side shaft portion of eccentric axial portion bolster, the centre distance of two rollers is D, this D0, the double-crank mechanism of D and four bars of two L shaped one-tenth, this double-crank mechanism can be adjusted to any position, even the theoretical traffic direction out of plumb of Liang Gegun center and flux-cored wire, also completely can adjust and obtain, the one section of side shaft portion that is just that in Figure 12, less circle represents, the circle of dotted line represents is if position and the outline of roller when concentric with side shaft portion, the position that the actual capabilities of the roll that two tangent circles of solid line represent are adjusted to.So, as shown in figure 13, position and outline when in Figure 13, the circle expression roll of dotted line is concentric with side shaft portion, the position that the actual capabilities of the rolls that two tangent circles of solid line represent are adjusted to.As can be seen from the figure, when being pinpoint between the framework of every row's roller die, if it is unified that the position of the die hole forming between two roller dies in each row can not guarantee, is also to exist the problem that the path of flux-cored wire between multipair rod is serpentine path.So the circle that adopts the roller die of eccentric shaft also can exist to cause because adjust eccentric shaft is the problem of conllinear not.
Passive roller die in the present embodiment is because its tube reducing efficiency is high, and four Roller. redress are convenient, as long as guarantee that the one side that holding screw stretches out is consistent with the distance of base, just can guarantee that four roll mandrels are all positioned at this perpendicular to the plane of flux-cored wire traffic direction, there is not in existing many row's roller dies the not problem of conllinear of the die hole between each row, thereby improved the tube reducing quality of flux-cored wire.
After passive roll stand frame is adjusted to the right place, roll stand frame holder angle 6 is fixed on base, and the afterbody of passive roll stand frame is clamped at every a pair roller frame holder angle, so just can prevent because passive roll stand frame length is larger, only rely on the alignment pin that is positioned at moving roll stand frame root to be not enough to guarantee completely that passive roll stand frame afterbody is more stable, so rely on roll stand frame holder angle, clamp the afterbody of passive roll stand frame, the afterbody that prevents passive roll stand frame is shaken, thereby affects the crudy of roll to flux-cored wire.
Flux-cored wire is added to man-hour, flux-cored wire is driven by drawing block and advances, in the process of advancing, the formed die hole of groove that runs into four passive rolls carries out tube reducing, and passive roll is rotated by operating flux-cored wire drive, from 4 directions, jointly retrain the deformation direction of welding wire, thus the tube reducing efficiency while having improved processing flux-cored wire.
