Description
Technical field
The utility model relates to the used drawing mould of a kind of steel wire industry, is applicable to drawing guy wire, steel cord, the used wire drawing die of line of cut.
Background technology
Wire drawing die is the important tool that metal wire drawing is produced, and whether the design of its shape and structure rationally has direct influence to production efficiency and product quality, and wherein the pass structure of nib is very crucial technical parameter.At present the steel wire market demand is increasing, to the core rod quality require increasingly highly, wherein line of cut requires higher with wire drawing die to the pass of core rod.The pass structure of wire drawing die mainly is made up of inlet region, lubricated district, workspace, sizing area and outlet area.Traditional linear pattern wire drawing die has strengthened the workspace owing to having removed lubricated district; When low speed drawing (3～8 meter per second); Can meet the demands, but when high speed drawing (12～18 meter per second), owing to lack abundant lubricant; So under the HTHP drawing condition, cause stripped thread or fracture of wire phenomenon easily, influence the quality and the production efficiency of steel wire.Simultaneously, the inlet region width of linear pattern wire drawing die also is one of important parameter, if wide, and wire drawing die easy-formation not then, its corner is damaged easily; If narrow, can't guarantee that then the lubricated district of wire drawing die satisfies instructions for use, influenced the quality and the wire drawing efficient of wire drawing die.In addition, the outlet area cone angle is less, and the wire drawing metal abrades the sizing area exit easily, goes out line mass thereby influence wire.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; A kind of novel wire drawing die with improved structure is provided, and this mould can improve lubricating condition, reduces the generation of stripped thread or fracture of wire phenomenon; Improve the antiwear property of mould; Improve wire quality, prolong the service life of mould, satisfy steel wire industry high speed drawing needs.
For realizing above-mentioned purpose; The wire drawing die of the utility model; Comprise the inlet region that is disposed in order, lubricated district, workspace, sizing area and outlet area, it is characterized in that: said inlet region unites two into one with lubricated district, and promptly the axle section profile line in inlet region and lubricated district is continuous straight line; Said straight line is connected with mould upper surface circular arc, and is connected with workspace upper outlet circular arc; The height h of said lubricated district/inlet region
1Be 60～80% of mould overall height H.
The diameter D in said inlet region/lubricated district
2Be mould diameter D
160～75%.
The height h of said workspace
2Be 1.0～3 times of sizing area aperture d, said workspace cone angle is 6 °～18 °, and reducing and reduce with the steel wire compression ratio.
The height h of said sizing area
3Be 0～0.5 times of mould sizing area aperture d.
Said outlet area height h
4Be 15%～25% of mould overall height H, said outlet area cone angle gamma is 80 °～100 °.
Between the workspace and sizing area of said pass, be arc transition between sizing area and the outlet area.
The utility model is distinguished owing to lubricating, the axle section profile line of inlet region is continuous straight line, and highly is increased to 0.65～0.8H by traditional mould base height 0.25H, and the lubricated district of increase can store a large amount of lubricants; Help more lubricant during high speed drawing and get into the workspace, reduced the drawing rub coefficient, the angle of wedge that utilizes workspace the first half to form simultaneously; Set up " wedge effect "; Form the more lubricating film of compact and firm at wire surface, improve lubricant effect, reduce wear; Effectively prevent the stripped thread or the fracture of wire phenomenon that occur in the drawing process, improved the quality and the production efficiency of steel wire; Through confirming diameter range (60～75% D of inlet region
1), guarantee the easy moulding of wire drawing die, make its corner be not easy breakage, improved the intensity of finished product wire drawing die, guaranteed that also the lubricated district of wire drawing die is enough to satisfy instructions for use simultaneously, improved the quality and the wire drawing efficient of wire drawing die; The outlet area cone angle is increased to 80 °～100 ° by traditional 50 °～60 °, and there is good cooling effect in scratch sizing area exit to wire simultaneously when effectively having prevented the wire outlet, thereby has improved the line mass that goes out wiry.The utility model wire drawing die is through reasonable optimizing structure and parameter, and the intensity of mould and antiwear property strengthen, and die life improves, and the wire quality of drawing is able to guarantee, satisfies the needs of high-tensile steel wires drawing.
