First collateral fagging 11 and the second collateral fagging 12 are for installing live roll 4 and format roll 5.First collateral fagging 11 and the second collateral fagging 12 can be all one piece of overall gripper shoes, and the two ends of often pair of live roll 4 and format roll 5 are installed on the first collateral fagging 11 and the second collateral fagging 12 respectively; Also can be multipair little gripper shoe, often pair of live roll 4 be installed on little a pair gripper shoe, and often pair of format roll 5 is also installed on little a pair gripper shoe.First collateral fagging 11 and the first collateral fagging 12 are vertically arranged, and surround the shaping channel 3 of cuboid, one end is as steel wire feed end 31, and for steel wire charging, the other end is steel wire discharge end 32, for the steel wire discharging after shaping.The live roll 4 being positioned at steel wire feed end 31 provides power for steel wire enters format roll 5.Live roll 4 and format roll 5 are horizontally disposed with, and are installed on the first collateral fagging 11 and the second collateral fagging 12, to be reduced to the frictional force between forming roll 5 and steel wire by bearing and bearing block.Spaced upper pressure wheel 53 and lower pressure wheel 54 are for waviness of being bent by steel wire, and in order to make steel wire uniform force, the press face of upper pressure wheel 53 and lower pressure wheel 54 is set to cambered surface, with the crest of steel wire or trough suitable.In steel wire direction of advance, the external diameter of upper pressure wheel 53 and the external diameter of lower pressure wheel 54 increase progressively successively, make the bending amplitude of steel wire ascending, are progressively formed into setting size, ensure formed precision and stablize, along with the distortion of steel wire aggravates, its width must reduce, therefore, distance between adjacent two upper pressure wheels 53 and adjacent two lower pressure wheels 54 is successively decreased successively, the trough that the width value successively decreased will meet upper pressure wheel 53 backfins that position is corresponding on adjacent two format rolls 5 is positioned at the same position of steel wire, guarantee that the upper pressure wheel 53 of often pair of format roll 5 and the backfin position of lower pressure wheel 54 pairs of steel wires remain on crest or the trough of last upper pressure wheel 53 and lower pressure wheel 54 backfin, so that progressively backfin is shaping, avoid the forced position of steel wire constantly to convert and cause intensity reduction even to damage.The quantity of upper pressure wheel 53 and lower pressure wheel 54 differs one, therefore, the center vertical cross section being positioned at the middle lower pressure wheel 54 of format roll 5 or upper pressure wheel 53 is positioned at same plane, center vertical cross section and central cross-section perpendicular to axial direction, distance decrease on same format roll 5 between arbitrary neighborhood two upper pressure wheel and lower pressure wheel is consistent, ensure steel wire linearly advance, improve shaping after form accuracy.The height of steel wire feeding-passage 43 and the thickness adaptation of steel wire, namely ensure that the thrust of upper live roll 41 and lower live roll 42 pairs of steel wires is suitable, prevent steel wire to be crushed, the width of steel wire feeding-passage 43 is determined according to the thickness of steel wire.The quantity of the logarithm of format roll 5, upper pressure wheel 53 and lower pressure wheel 54, upper pressure wheel 53 and the external diameter increasing degree of lower pressure wheel 54 and the maximum outside diameter of upper pressure wheel 53 and lower pressure wheel 54 are selected according to steel wire compact dimensions.During use, steel wire feeding-passage 43 is delivered in one end of steel wire, start power set 2, power set 2 drive live roll 4 to rotate, live roll 4 compacting steel wire, and pull steel wire to move to format roll 5, steel wire is under the effect of upper pressure wheel 53 and lower pressure wheel 54, and pressurized is bent into waveform.Along with the reach of steel wire, the external diameter of upper pressure wheel 53 and lower pressure wheel 54 constantly increases, and crest and the trough value of steel wire increase gradually, until from 32 discharging of steel wire discharge end time, the bending radian of steel wire reaches setting size.This steel wire bender utilizes many format rolls 5 progressively bending forming, and formed precision is high, and reduces the internal stress of steel wire, its shaping rear form trait is stablized, can not be out of shape, thus guarantee serviceability under the effect of its own resilient.Meanwhile, this device can realize automated production, continuous bending, and working (machining) efficiency is high.
In order to the steel wire making this steel wire bender be applicable to multiple different-thickness and width, and can the steel wire of the shaping multiple degree of depth, described frame 1 is provided with governor motion 6, described frame 1 is provided with installs through hole 111, mounting blocks 112 moving up and down is provided with in described installation through hole 111, the two ends of described upper live roll 41 and top roll 51 are installed on mounting blocks 112, and described governor motion 6 is connected with mounting blocks 112.Because mounting blocks 112 can move up and down, and governor motion 6 is connected with mounting blocks 112, makes governor motion 6 can regulate the height of mounting blocks 112.Again because the two ends of upper live roll 41 and top roll 51 are installed on mounting blocks 112, mounting blocks 112 can drive live roll 41 or top roll 51 to move up and down.The height of lower live roll 42 remains unchanged, the height and position of upper live roll 41 is regulated by governor motion 6, thus regulate the height of steel wire feeding-passage 43, make the thickness of itself and steel wire adaptive, guarantee that the active force of live roll 4 pairs of steel wires is moderate, steel wire can either be promoted smoothly and advance, the excessive steel wire that causes of pressure can be avoided again to be crushed distortion, affect intensity, make steel wire feeding-passage 43 can be applicable to the steel wire be made into by the steel wire of different-diameter simultaneously.The height of lower roll 52 remains unchanged, and when the bending degree of depth of steel wire is larger, regulates the height of each top roll 51, top roll 51 is reduced with the distance of lower roll 52, deepens the press-bending degree of depth; When the bending degree of depth of steel wire is less, move on each top roll 51, increase and the distance of lower roll 52, the bending degree of depth is reduced, thus realize employing bender just can the steel wire of the shaping multiple different bending degree of depth.When the width of steel wire raw material is larger, reduces top roll 51 and the distance of lower roll 52, deepen the backfin degree of depth of steel wire; When the width of steel wire raw material is less, increase the distance of top roll 51 and lower roll 52, reduce the backfin degree of depth of steel wire, thus the shaping rear certificate of the steel wire raw material of different in width can be made to have identical width, be applicable to the wallboard of multiple same widths, different-thickness.
In addition to the implementation, governor motion 6 also can be connected with lower roll 52 with lower live roll 42, and the height of upper live roll 41 and top roll 51 remains unchanged, by the steel wire regulating the height of lower live roll 42 and lower roll 52 to realize bending different size specification.In addition, the height of lower live roll 42, lower roll 52, upper live roll 41 and top roll 51 can all be regulated by governor motion 6, when the bending degree of depth of steel wire is less, by rising top roll 51 for a pair or several near steel wire discharge end 32, the lower roll 52 of correspondence is transferred, reduce the logarithm of the format roll 5 that steel wire passes through, thus reduce the bending degree of depth.When the bending degree of depth of steel wire is larger, then transfer to original position by top roll 51, lower roll 52 rises to original position, deepens the bending degree of depth of steel wire.
Described governor motion 6 comprises screw mandrel 113, described installation through hole 111 is horizontally disposed with, described frame 1 is provided with and extends to from frame 1 upper surface the screwed hole installing through hole 111, described screw mandrel 113 passes screwed hole and closes with corresponding threaded holes, and lower end and the mounting blocks 112 of described screw mandrel 113 are fixedly linked.Through hole 111 is installed can be horizontally disposed with, also can vertically arranges, when it is vertically arranged, in order to be adjusted to the height of forming roll 5, also need in frame 1, arrange the groove moved up and down for format roll 5, therefore, preferably, through hole 111 is installed and adopts horizontally disposed mode.First collateral fagging 11 is arranged and installs through hole 111, install in through hole 111 and arrange mounting blocks 112, the length of mounting blocks 11 and width are all less than installs through hole 111, so that freely up and down move.First collateral fagging 11 arranges the screwed hole passing through and extend to from its surface and install through hole 111, close with screw mandrel 113 and corresponding threaded holes again, screw mandrel 113 passes screwed hole and is fixedly connected with mounting blocks 112, and the correspondence position of the second collateral fagging 12 adopts identical structure.Rotary screw 113, screw mandrel 113 drives mounting blocks 112 to move up and down, and mounting blocks 112 drives upper live roll 41 or top roll 51 to move up and down, and reaches the object of adjustment.Screw body changes circular motion into rectilinear motion, and regulated quantity easily controls, and can realize minute sized adjustment, guarantees the dimensional accuracy regulated, and ensures formed precision and the quality of steel wire.In addition, also hydraulic jack or jack can be set in installation through hole 111, the height of upper live roll 41 and top roll 51, lower live roll 42 and lower roll 52 is regulated.
When the driving force that each position of steel wire is subject to is uneven, can offset towards width time mobile, after causing bending, shape is nonstandard, therefore, the two ends of format roll 5 are respectively provided with the position-limited wheel 56 cooperatively interacted for a pair, the position-adjustable of often pair of described position-limited wheel 56 on format roll 56; It is trapezoidal limiting section 561 and columniform forming part 562 that described position-limited wheel 56 comprises longitudinal section, described limiting section 561 and forming part 562 rounding off, and described limiting section 561 equals the ultimate range of forming part 562 to format roll 5 center to the minimum range at format roll 5 center, and forming steel wire limit channels 58 between often pair of position-limited wheel 56 mating surface, the distance between two pairs of position-limited wheels 56 at same format roll 5 two ends is adjustable; From steel wire feed end 31 to the direction of steel wire discharge end 32, the distance between two pairs of position-limited wheels 56 at format roll 5 two ends is successively decreased successively, and it is consistent that amplitude of successively decreasing and the width of steel wire reduce amplitude.Limiting section 561 longitudinal section is trapezoidal, and outer surface is the axial slope that the gradient is larger, to provide enough large resistance, plays good barrier effect.The circumferential surface of forming part 562 can be processed as arc surface, adapts with steel wire crest or trough shape, guarantees that the shape of steel wire is more regular.Distance between mating surface, namely the height of steel wire limit channels 58 should equal or slightly larger than the thickness of steel wire.From steel wire feed end 31 to the direction of steel wire discharge end 32, distance between two pairs of position-limited wheels 56 at format roll 5 two ends is successively decreased successively, it is consistent that amplitude of successively decreasing and the width of steel wire reduce amplitude, enable the dual-side of steel wire be arranged in steel wire limit channels 58 in Forging Process always, ensure limit effect.During two bending and moldings, the dual-side of steel wire enters the steel wire limit channels between upper limit wheel and lower limit wheel, when the driving force that steel wire is subject to is uneven, there is the movement tendency offseted to one side, the side of steel wire is blocked by the cooperation inclined-plane that the gradient is larger, prevent it from offseting, steel wire is advanced along the direction perpendicular to format roll 5, guarantees shaping rear shape criteria; When steel wire out enters next format roll 5 from last format roll 5 simultaneously, position-limited wheel 56 can produce by both sides to middle extruding force steel wire, under the squeezing action of position-limited wheel 56, steel wire width diminishes, the position of Wave crest and wave trough changes, the upper pressure wheel 53 of the position of Wave crest and wave trough and next format roll 5 and the position of lower pressure wheel 54 are consistent, are conducive to ensureing steel wire formed precision and intensity.In addition, also horizontal beam 13 can be set for the top of the first collateral fagging 11 between adjacent two format rolls 5 and the second collateral fagging 12 as shown in Figure 9, the length direction of horizontal beam 13 arranges mounting hole, arrange connecting rod 14 in mounting hole, connecting rod 14 can move along steel wire width in mounting hole.The lower end of connecting rod 14 is fixedly installed baffle plate 15, and baffle plate 15, for blocking the side of steel wire, prevents it from offseting; Matching with nut 16 in the upper end of connecting rod 14, plays the role of positioning.When utilizing governor motion 6 to have adjusted the height of each pair of top roll 51 and upper live roll 41, when the bending degree of depth of often pair of format roll 5 pairs of steel wires is changed, the width of steel wire changes, or when adopting the steel wire of different in width as production raw material, the change width of steel wire can make its dual-side depart from steel wire limit channels 58, at this moment, in order to ensure limit effect, the position-adjustable of often pair of described position-limited wheel 56 on format roll 5, position-limited wheel 56 and format roll 5 threaded engagement can be made, or position-limited wheel 56 and format roll 5 are slidably matched, re-use alignment pin or dog screw carries out axial location to position-limited wheel 56.When the press-bending degree of depth of often pair of format roll 5 to same width steel wire changes, or when adopting different in width steel wire to be raw material, the position of adjustment position-limited wheel 56, makes the dual-side of steel wire be positioned at steel wire limit channels 58, prevents steel wire from offseting.
