Abstract

The utility model relates to a dry wiredrawing gully cooling mould, including die sleeve and mold core, the mold core is inlayed inside the die sleeve, characterized by: spiral notch is evenly seted up along the axial to the die sleeve surface. The mold core is cylindrical, and the mold core inner chamber has been seted up to the inside of mold core, and the mold core inner chamber is mold core entry end, deformation range and mold core exit end from entry end to exit end in proper order, and the deformation range is distinguished for the mold core sizing with the one end that the mold core exit end is connected for mold core compression zone, deformation range with the one end that the mold core entry end is connected. The axis of mold core and the dead in line of die sleeve, the dead in line of mold core entry end, deformation range and mold core exit end. The tank bottom distance surperficial apart from the mold core of spiral notch is not less than 6mm. Lubricated liquid guide hole has been seted up on the mold core. The utility model discloses a mold core heat dissipation is faster, has improved the area of contact of mould overcoat with the recirculated cooling water of flow, has improved cooling efficiency.

Description

Dry wire drawing gully cooling mould
Technical field
This utility model 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
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of dry wire drawing gully cooling mould Tool, 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 this utility model, described dry wire drawing gully cooling mould, including die sleeve and core rod, Core rod 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.
This utility model has the advantages that this utility model offers spiral notch at die sleeve outer surface, due to Spiral notch reduces to the internal core rod inlayed distance, and therefore core rod dispels the heat faster;Owing to offering spiral notch so that Whole die coat 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 described in the utility model 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 utility model is described in further detail.
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 described in the utility model cooling mould, including die sleeve 1 and core rod 2, core rod 2 is inlayed It is embedded in die sleeve 1 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.
This utility model offers spiral notch at die sleeve outer surface, due to spiral notch to the internal core rod inlayed away from From reduction, therefore core rod dispels the heat faster;Owing to offering spiral notch so that whole die coat and the circulating cooling of flowing The contact area of water improves about 60%, improves cooling effectiveness.
