Abstract
The utility model provides a drawing die for a copper-coated aluminum row. The drawing die comprises a die body, wherein a die hole is formed in the die body; a lubricating cone is arranged at the upper part of the die body; a sizing zone is arranged in the middle of the die body; an exit cone is arranged at the lower part of the sizing zone; a die bearing is arranged between the lubricating cone and the sizing zone; the taper of the die bearing is that the 2Alpha is equal to 18 degrees. According to the drawing die for the copper-coated aluminum row, since the lubrication taper is designed to be an inverted sawtooth, the lubrication effect can be enhanced, and the dry frication on the surface can be prevented; since the die bearing is arranged between the lubricating cone and the sizing zone, the defects of copper layers, raised grain, fish scale and the like appear on the surface of drawn material are avoided; since the deflection of discharged material is restricted by the sizing zone with an inverted taper, the deflection of the aluminum row has an increasing effect, the combination is strengthened, and the frictional force between the die and supplied material is reduced; the exit taper of the die is enlarged, the residual metal chip after drawing can be removed effectively, and the metal bright surface without scratches be ensured.
Description
Technical field
The utility model belongs to the composite material manufacture field, relates in particular to a kind of drawing mould for copper clad aluminum wire.
Background technology
The copper clad aluminum wire material is a kind of cladded type composite, and cross sectional shape is wide flat, and supplied materials is processed by square copper-clad aluminium bar base.The main work flow of this copper clad aluminum wire is rolling and drawing procedure, in drawing procedure, the structure of conventional copper bar drawing mould is comprised of lubrication belt and sizing area two parts, lubrication belt is the horn mouth with certain taper, this tapering is generally 2 * 30 ° of left and right, sizing area is the Main Deformation of material, and its cross section conventional design is straight rectangle region, is not with tapering.With conventional copper bar drawing mould, come the drawing copper clad aluminum wire to have following problem: 1. the drawing deformation heat of copper clad aluminum wire is larger, lubricated tapering lubricant effect is difficult to satisfy the demands, produce the dynamic friction heating between copper clad aluminum material and mould, easily damage material surface; 2. use the copper clad aluminum wire surface after conventional drawing mould drawing to there will be the copper layer wavy skin effect phenomenon to occur, surface configuration is the fish scale sheet, is not suitable for the copper clad aluminum wire drawing and uses, and this is owing in sizing area and lubricated interval, there is no buffer structure design; 3. conventional copper bar drawing mould sizing area is straight outlet, and this structure can not realize between copper aluminium that, in conjunction with stiffening effect, the copper clad aluminum wire Cu and Al combination intensity that drawing goes out is lower, can not meet instructions for use; 4. conventional drawing mould does not have clear and definite chip removal design, the easy residual scuffing material surface of surface metal bits.
Summary of the invention
The utility model provides a kind of drawing mould for copper clad aluminum wire in order to address the above problem.
The technical solution of the utility model is achieved in that a kind of drawing mould for copper clad aluminum wire, comprise mold, be provided with nib in mold, mold top is provided with Lubricanting cone, middle part is provided with calibrating strap, the calibrating strap bottom is provided with out prostomum, is provided with the work band between Lubricanting cone and calibrating strap, and the tapering of work band is 2 α=18 °;
Described Lubricanting cone is for falling zigzag, and coning angle is 40 °～43 °;
Described calibrating strap is back taper;
Lubricated section length is 2.6 times of sizing area length;
The described tapering that goes out prostomum is 10 °～12 °.
The beneficial effects of the utility model are: the design of falling the zigzag of the lubricated tapering of the utility model can strengthen lubricant effect, meets the drawing lubrication demand of copper clad aluminum wire, has prevented the surface dry friction; Designed the work band between Lubricanting cone and sizing area, this part can realize cushioning the friction of metal material and sizing area, has avoided the material surface after the drawing to there will be the defects such as copper layer emersion wave Slippage, fish scale sheet; Have the deflection of the calibrating strap restriction discharging of back draught, make copper aluminium deflection that the effect increased progressively be arranged, strengthen combination, the back draught design of sizing workspace can also reduce the frictional force of mould and supplied materials; Strengthen the mould outlet tapering, effectively get rid of drawing residual metal bits, guarantee that the surface metal light is without scratching.
The accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
Part explanation: 1, Lubricanting cone, 2, the work band, 3, calibrating strap, 4, go out prostomum, 5, mold, 6, nib.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: a kind of drawing mould for copper clad aluminum wire, comprise mold 5, be provided with nib 6 in mold 5, mold 5 tops are provided with Lubricanting cone 1, and Lubricanting cone 1 coning angle is 43 °, middle part is provided with calibrating strap 3, calibrating strap 3 is back taper, between Lubricanting cone 1 and calibrating strap 3, is provided with work band 2, and work is 2 α=18 ° with 2 tapering, calibrating strap 3 bottoms are provided with out prostomum 4, and the tapering that goes out prostomum 4 is 12 °.
Lubricanting cone 1 adds lubricant by Lubricanting cone 1 while being stretching in nib 6, guarantee lubricated fully on one side, and take away metal due to distortion and fricative heat, tapering is designed to 43 ° for lubricated cone angle, lubricated tapering is designed to down zigzag, can strengthen the storage capacity of lubricating fluid, can effectively strengthen lubricated and cooling, work is major parts that metal is realized transition deformation with 2, it makes the distortion of metal Ci district, and the size and dimension of acquisition defined, calibrating strap 3 is designed to the back draught type, because the elastic deformation amount of copper aluminum composite material is different from single copper material or aluminium, there is certain tapering can avoid, after the distortion of copper aluminium, larger elastic recovery amount is arranged, thereby avoid the material calibrating strap long and material friction.Such design has lengthened the life-span of mould on the one hand, has also reduced the frictional resistance while stretching simultaneously; Designed mould outlet cone 4, the mould outlet tapering of 12 ° is scratched in the time of preventing coming off of mould outlet end and metal depanning, such design meets the characteristics of the strain that copper aluminium is larger, larger tapering easily comes off residual copper scale simultaneously, the mold material that the drawing copper clad aluminum wire is used is the wolfram steel sintered-carbide die, lubricated section length is 2.6 times of sizing area length, and the tapering of work band is 2 α=18 °, the length hg=(D0-d) of work band/2tan α.
