The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The nouns of locality such as " left side " " right side " occurring in the utility model, only play the effect that coordinates accompanying drawing explanation technology contents, and not should be understood to be the concrete restriction to the technical program.
Wire drawing die box, comprises the box body 200 of hollow, and described box body 200 left sides are fixedly installed thread guide devices 100, and right side is connected with the first mould 400 and the second mould 500 by oscillating bearing 300; The middle part of described the first mould 400 and the second mould 500 all connects and is provided with centre bore; The center line of the center line of described the first mould 400 centre bores and the second mould 500 centre bores is on same straight line; Described oscillating bearing 300 outsides have contacted clamping screw 600, and described clamping screw 600 is provided with the hollow hole that left and right connects; The hollow hole of described clamping screw 600 is connected with the centre bore of the second mould 500.
During work, metal wire rod, through alignment and the traction of thread guide devices 100, enters box body 200.Box body 200 internal storage have the wire drawing powder of the lubrication of playing.Metal wire rod through after wire drawing powder respectively after the first mould 400 and the second mould 500, outlet from clamping screw 600.The entrance of the centre bore of described the first mould 400 and the second mould 500 presents bell-mouthed shape, is divided into entrance, the profit section of changing, positioning section and outlet section.Than the Wire drawing die box that only adopts single wire-drawing die, the technical program adopts two coaxial wire-drawing dies that arrange.Metal wire rod after this programme post processing, the wire drawing powder of its surface attachment is more dense, is difficult for dry linting, has reduced the wire drawing friction of follow-up passage, has reduced motor power consumption, has improved the quality of finished product.As shown in Figure 3, use two coaxial wire-drawing dies that arrange of this programme less than using the follow-up wire drawing passage average current of single wire-drawing die, illustrate that after two coaxial wire-drawing dies that arrange that use this programme, the pulling capacity of each passage is less.As shown in Figure 4, use two coaxial wire-drawing dies that arrange of this programme lower than using the follow-up wire drawing passage outlet temperature of single wire-drawing die, illustrate that after two coaxial wire-drawing dies that arrange that use this programme, wire drawing frictional heat is less.
Described thread guide devices 100 comprises the first pair roller 101 and the second pair roller 102; The axis of described the first pair roller 101 vertically arranges, and metal wire rod is played to level correction; The axis of described the second pair roller 102 is horizontally disposed with, and metal wire rod is played to vertical correction.
Described oscillating bearing 300 comprises the first circular cone ring 340 of outer ring 310, bed course 320, inner ring 330, hollow and the second circular cone ring 350 of hollow.
Described outer ring 310 is fixedly installed on the exit of box body 200.310 external diameter face width degree middle parts, described outer ring are provided with the outer lubrication groove 311 of a ring, and described outer ring 310 is radially provided with the outer lubrication hole 312 being communicated with outer lubrication groove 311.
Described bed course 320 is embedded in outer ring 310 Internal Spherical Surface, and the Internal Spherical Surface left and right sides of described outer ring 310 is provided with the baffle plate 313 of conflict bed course 320, and described bed course 320 adopts self-lubricating materials, has lubrication.After bag pressure, bed course 320 is limited in the Internal Spherical Surface middle part of outer ring 310 by baffle plate 313, is difficult for making bed course 320 and outer ring 310 to produce relative sliding, thereby prevents that bed course 320 from coming off.And the thickness of described bed course 320 exceeds baffle plate 313, the normal wear of bed course 320 can not make baffle plate 313 touch inner ring 330.On described bed course 320, be provided with the middle lubrication hole 321 being communicated with outer lubrication hole 312.
The middle part of described inner ring 330 spherical outside surfaces is provided with a ring lubricating groove 331.Lubricating oil lubrication groove 311 from outer ring 310 outer lubrication hole 312 and middle lubrication hole 321 of flowing through successively arrives lubricating grooves 331, and then circulation is to whole working face.The use of lubricating oil, has further reduced the resistance that bearing rotates, and the less wearing and tearing of bed course 320, has extended the service life of bearing.
Fit with the inclined-plane of the first circular cone ring 340 and the second circular cone ring 350 respectively in the aperture surface middle part projection of described inner ring 330 and both sides.Described the first circular cone ring 340 and the second circular cone ring 350 are bolted, and have guaranteed that every conical blocks all can provide enough axial support power.The middle part of described the first circular cone ring 340 is fixedly installed the first mould 400, and the middle part of described the second circular cone ring 350 is fixedly installed the second mould 500.The utility model can plug the mould of different-diameter by changing the first circular cone ring 340 and the second circular cone ring 350 of different inner diameters, has increased adaptability and the versatility of this Wire drawing die box, reduces cost.
Existing Wire drawing die box and wire drawing machine are fixing with bolt, there is no strict detent mechanism.Not not accurate while locating due to both, and when work bolt looseness cause the position of Wire drawing die box and wire drawing machine to be offset, thereby make the center of metal wire rod and the center of wire drawing die not on a line, wire drawing die radial force is inhomogeneous, cause the defects such as wire ellipse, plucking, affect product quality, and wire drawing die wearing and tearing are also inhomogeneous, rapid wear has shortened the life-span of wire drawing die, has increased use cost.
This Wire drawing die box has adopted oscillating bearing 300.Oscillating bearing 300 can bear certain axial force and radial load, and can carry out angular movement, can adjust adaptively the outlet angle of metal wire rod, thereby guarantees wire drawing die center and metal wire drawing direction all the time point-blank.
The utility model is illustrated according to embodiment, is not departing under the prerequisite of present principles, and this device can also be made some distortion and improvement.It should be pointed out that all employings are equal to the technical scheme that the modes such as replacement or equivalent transformation obtain, and all drop in protection domain of the present utility model.
