Description
Technical field
The present invention relates to a kind of metal material processing mould, relate in particular to a kind of wire-drawing die that draws copper wire to use.
Background technology
The wire-drawing die that China's wires and cables industry uses is of a great variety, alloy mould, wolfram steel mould, diamond mould etc. are arranged, these mould process performances, anti-wear performance has different shortcomings with heat dispersion, add the structural design of mould self, tend to influence service life and the wire drawing efficient of this mould, thereby increased the production cost of enterprise, also reduced production efficiency.
Summary of the invention
The objective of the invention is to the above-mentioned deficiency at existing wire-drawing die, a kind of wire-drawing die that draws copper wire to use is provided, with the raising drawing speed, thereby enhance productivity.
In order to achieve the above object, the present invention has adopted following technical scheme:
A kind of wire-drawing die, comprise die ontology, be provided with a cross section along axis direction in the die ontology and be circular through hole, columned metal material enters from an end of through hole under external force, leave from the other end, through hole includes smooth connection and coaxial inlet region, compressional zone, sizing area and outlet area successively, die ontology adopts the glomerocryst diamond material to make, the compression angle γ of compressional zone is 28 ° of 28`, sizing area is cylindrical, and the axial length of sizing area is 1.1 times of the sizing area diameter, and the axial length of compressional zone is to wait to draw 1.2 times of material diameter.
These three parameters of the axial length of the compression angle of wire-drawing die compressional zone, the axial length of compressional zone and sizing area are being brought into play crucial effect in wire drawing efficient: the compression angle γ of (1) compressional zone and the axial length of compressional zone are two decisive parameters that ensure metal plastic deformation and compressional zone distortion coupling; The axial length of compressional zone is more long, and wire rod fraction time in wire-drawing die is more long, and the wire-drawing die temperature is raise, thus the wearing and tearing that strengthened wire-drawing die; The axial length of compressional zone is too short, and wire rod is sharply compressed, and because the compression of plastic deformation of metal and compressional zone does not match, wire rod is easily broken, thereby causes the wire drawing machine can't normal boot-strap; (2) axial length of sizing area is long, wire rod is just long in the run duration in this district, can cause two negative effects, the one, the lubricating oil that is added by the inlet angle place does not catch up with, thereby influenced drawing speed, the 2nd, when the long meeting of sizing area axial length makes the wire rod depanning easily diameter drawn little, thereby influence the electric conductivity of copper conductor; The axial length of sizing area is too short, then can make wire surface rough, and easily laterally cracking causes broken string, and the axial length of sizing area is 1.1 times of sizing area diameter, then is the relatively reasonable length according to the hot strength design of copper material.
In addition, glomerocryst diamond material quality is hard, and anti-wear performance is good, perfect heat-dissipating, and processing back nib smooth surface, long service life is about other material and makes 6 times of mould.Therefore, this mould adopts the glomerocryst diamond material and cooperates above-mentioned three key parameters, can make drawing speed bring up to 2100m/min by original 1300m/min, has improved speed of production and operating efficiency greatly.
Preferably, the inlet angle β of inlet region is 60 °.When work, wire rod drives lubricating oil, brings lubricating oil into inlet region, makes lubricating oil be full of the inlet region, plays effect lubricated and the cooling wire-drawing die.
Particularly, the angle of outlet α of outlet area is 100 °～120 °.
Preferably, smooth connection has the back taper district between sizing area and the compressional zone, and the angle in back taper district is identical with angle of outlet α.Owing to the copper wire drawing machine is slip-type drawing machine, the relative slip of copper cash and wire drawing drum meeting in pulling process, and copper cash can slightly expand after having crossed sizing area, the back taper district relies on the expansion of copper cash to prevent from sliding behind the copper cash, thereby prevents the drawing process interrupt line.
The invention discloses a kind of wire-drawing die, this wire-drawing die body adopts the glomerocryst diamond material to make, and by wire-drawing die parameters reasonable in design, make drawing speed bring up to 2100m/min by original 1300m/min, improved speed of production and operating efficiency greatly.
Description of drawings
Fig. 1 is the axial section schematic diagram of wire-drawing die;
Fig. 2 is the axial section schematic diagram that is provided with the wire-drawing die of copper wire;
Number in the figure: inlet region 1, compressional zone 2, sizing area 3, back taper district 4, outlet area 5.
The specific embodiment
Below in conjunction with specific embodiment technical scheme of the present invention is done further explanation clearly and completely.
Embodiment
Embodiment discloses a kind of wire-drawing die, in conjunction with Fig. 1 and Fig. 2, this wire-drawing die comprises die ontology, be provided with a cross section along axis direction in the die ontology and be circular through hole, columned metal material enters from an end of through hole under external force, leave from the other end, through hole includes smooth connection and coaxial inlet region 1 successively, compressional zone 2, sizing area 3, back taper district 4 and outlet area 5, die ontology adopts the glomerocryst diamond material to make, the compression angle γ of compressional zone 2 is 28 ° of 28`, sizing area 3 is cylindrical, and the axial length of sizing area 3 is 1.1 times of the sizing area diameter, and the axial length of compressional zone 2 is to wait to draw 1.2 times of material diameter.
Glomerocryst diamond material quality is hard, and anti-wear performance is good, perfect heat-dissipating, and processing back nib smooth surface, long service life is about other material and makes 6 times of mould.
The design of the compression angle γ of compressional zone 2 and compressional zone 2 length has ensured that the compression of copper material plastic deformation and compressional zone 2 is complementary; The design of sizing area 3 length meets the hot strength of copper material.The design of three parameters makes drawing speed bring up to 2100m/min by original 1300m/min in conjunction with the use of glomerocryst diamond material.
The inlet angle β of this wire-drawing die inlet region 1 is 60 °.When work, wire rod drives lubricating oil, brings lubricating oil into inlet region 1, makes lubricating oil be full of inlet region 1, plays effect lubricated and the cooling wire-drawing die.
