Description
Technical field
The present invention relates to a kind of cooling mould, especially a kind of dry wire drawing gully cooling mould.
Background technology
Dry drawing is to carry out drawing by reel, mould, recirculated cooling water, powdered lubricant, and at present, drawing mill uses
Wolfram steel wire drawing die carries out wire drawing, and its inside configuration is core rod, and outer portion is ganoid die sleeve, and both inlay and combine group
Become a wire-drawing die.
There is cooling defect, because die sleeve is cylinder, its smooth surface in existing dry wire drawing mould, cooling water is on surface
One flowing, flowing velocity is fast, and so poor to mould cooling effect, wire temperature is higher, can affect steel wire toughness and increase fracture of wire
Probability, finally affect the reduction of product quality and production efficiency, the increase of waste silk.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of dry wire drawing gully cooling mould,
Core rod dispels the heat faster, improves the contact area of die coat and the recirculated cooling water of flowing, improves cooling effectiveness.
The technical scheme provided according to the present invention, described dry wire drawing gully cooling mould, including die sleeve and core rod, core rod
It is embedded in inside die sleeve；It is characterized in that: the most uniformly offer spiral notch at described die sleeve outer surface.
Further, described core rod is cylindrical, and the inside of core rod offers core rod inner chamber, core rod inner chamber from arrival end to
The port of export is followed successively by mold core gate end, deformed area and the core rod port of export, and one end that deformed area is connected with mold core gate end is core rod
Compressional zone, one end that deformed area is connected with the core rod port of export is core rod sizing area.
Further, the axis of described core rod and the dead in line of die sleeve, mold core gate end, deformed area and the core rod port of export
Dead in line.
Further, the distance of the bottom land distance core surface of described spiral notch is not less than 6mm.
Further, described core rod offers lubricating fluid guide hole.
Further, described mold core gate end is connected with deformed area one end internal diameter and the core rod port of export are positioned at exit
Internal diameter is equal；The internal diameter of described core rod compressional zone is not more than the internal diameter of mold core gate end, and the internal diameter of core rod compressional zone is not less than
The internal diameter of core rod sizing area.
The method have the advantages that the present invention offers spiral notch at die sleeve outer surface, due to spiral groove
Mouth reduces to the internal core rod inlayed distance, and therefore core rod heat radiation is faster；Owing to offering spiral notch so that whole mould
Overcoat improves about 60% with the contact area of the recirculated cooling water of flowing, improves cooling effectiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of dry wire drawing gully of the present invention cooling mould.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
Shown in Fig. 1～Fig. 2: as described in dry wire drawing gully cooling mould include die sleeve 1, core rod 2, core rod inner chamber 21, mould
Core arrival end 211, deformed area 212, the core rod port of export 213, core rod compressional zone 214, core rod sizing area 215, lubricating fluid guide hole 22,
Spiral notch 3 etc..
As it is shown in figure 1, dry wire drawing gully of the present invention cooling mould, including die sleeve 1 and core rod 2, core rod 2 is embedded in
Die sleeve 1 is internal, the most uniformly offers spiral notch 3 at die sleeve 1 outer surface.
Described core rod 2 is cylindrical, and the inside of core rod 2 offers core rod inner chamber 21, core rod inner chamber 21 from arrival end to going out
Mouth end is followed successively by mold core gate end 211, deformed area 212 and the core rod port of export 213, and deformed area 212 is connected with mold core gate end 211
One end be core rod compressional zone 214, one end that deformed area 212 is connected with the core rod port of export 213 is core rod sizing area 215.
The axis of described core rod 2 and the dead in line of die sleeve 1, mold core gate end 211, deformed area 212 and the core rod port of export
The dead in line of 213.
The distance on bottom land distance core rod 2 surface of described spiral notch 3 not less than 6mm, prevent die sleeve 1 occur crackle or
Split.
Described core rod 2 offers lubricating fluid guide hole 22, in processing, the internal chamber wall of core rod 2 scribbles lubricating fluid, subtracts
Miscellaneous goods and the frictional force of core rod 2 inner chamber, make the course of processing be easier to.
One end internal diameter and the core rod port of export 213 that described mold core gate end 211 is connected with deformed area 212 are positioned at exit
Internal diameter is equal；The internal diameter of described core rod compressional zone 214 is not more than the internal diameter of mold core gate end 211, and core rod compressional zone 214 is interior
Footpath is not less than the internal diameter of core rod sizing area 215.
The present invention offers spiral notch at die sleeve outer surface, owing to spiral notch is to the internal core rod inlayed distance fall
Low, therefore core rod dispels the heat faster；Owing to offering spiral notch so that the recirculated cooling water of whole die coat and flowing
Contact area improves about 60%, improves cooling effectiveness.
