Description

A kind of wire drawing die

Technical field

The utility model is related to a kind of steel wire wire-drawing technology field, more particularly to a kind of wire drawing die.

Background technology

Metal drawing belongs to metallic article production pre-processing system, and its effect is by wire drawing machine by wire rod or bar Drawing process, make diameter, circularity, internal structure, surface smoothness and the aligning degree of wire rod or bar all reach requirement.Draw Silk machine diaphragm capsule is used to fix wire drawing die and provides powdered lubricant.

Conventional dry-type wire drawing machine die box, including lubrication at present box body and mould box body, equipped with lubrication in lubricating box body Cooling water is housed, wire drawing die is arranged in mold box body in powder, mold box body.Steel wire enters wire drawing die by lubrication box body, will Powdered lubricant brings wire drawing die into, plays a part of lubrication.

There is following defect in the wire drawing machine mould：Only one of which Working mould, lubricant effect is not good in production process, production efficiency Low, wire drawing powder cannot sufficiently be expressed to Steel Wire Surface, easily cause steel wire wear.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of simple structure, wire drawing powder can be expressed into steel wire table The wire drawing die in face.

In order to solve the above technical problems, the technical solution of the utility model is：A kind of wire drawing die, in die sleeve, its Innovative point is：Including Working mould and pressure mould, the Working mould is the column that stepped hole is offered at an axis, described Stepped hole is made up of hole A and hole B, and the hole A apertures are less than hole B, and the hole A is nested with and is combined with a mold core A, the pressure mould It is a coaxial column being nested in work nib B, being opened up at its axis has a core rod in a mesopore, the mesopore B B, the mold core A is corresponding with mold core B, there is the through hole passed through for steel wire.

Further, in described pressure mould one end insertion work nib B, and connection between the two is threaded connection, pressure The other end of power mould is that the screw thread for exposing Working mould tightens end.

Further, the Working mould end and pressure mould screw thread have seal washer between tightening end.

Further, contact end face of the mold core A with mold core B is the concave surface to central concave, the mold core B and core rod The end face that A is in contact is the convex surface of the outwardly convex coordinated with mold core B concave surface.

The utility model has the advantage of：

（1）Common die does not have pressure mould, is directly a Working mould, and lubricant effect is not good in production process, production effect Rate is low.After improvement, every time can make wire drawing powder be expressed to Steel Wire Surface using pressure mould, and lubricant effect is obviously improved, and improve effect Rate, quality is guaranteed.

（2）Using threaded connection, connection is reliable, replacing easy to disassemble.

（3）Seal washer can slow down the abrasion between two moulds, increase sealing, prevent powdered lubricant from revealing.

（4）It is attached using male and fomale(M＆F) between mold core A and mold core B, is not only easy to positioning to dock, and connectivity is good.

Brief description of the drawings

Fig. 1 is a kind of schematic diagram of wire drawing die of the utility model.

Fig. 2 is a kind of schematic diagram of wire drawing die Working mould of the utility model.

Fig. 3 is a kind of schematic diagram of wire drawing die pressure mould of the utility model.

Specific embodiment

As shown in figure 1, the utility model discloses a kind of wire drawing die, in die sleeve, including Working mould 2 and pressure mould 4, Working mould 2 is the column that stepped hole is offered at an axis, and stepped hole is made up of hole A21 and hole B22, hole A21 apertures Less than hole B22, hole A21 is nested with and is combined with a mold core A 3, and pressure mould 4 is a coaxial column being nested in work nib B21 Body, being opened up at its axis has a mold core B 5, mold core A 3 and the correspondence of mold core B 5 in a mesopore 42, mesopore B22, supply steel wire The through hole 1 for passing through.

As shown in Fig. 2 in the one end of pressure mould 2 insertion work nib B22, and connection between the two is threaded connection, pressure The other end of power mould 4 is that the screw thread for exposing Working mould 2 tightens end 41, and specifically, the screw thread tightens end 41 and is covered in the end of pressure mould 4 Portion, section is polygon, and matchedly, the other end of Working mould 2 also tightens end with screw thread.

41 contact positions of end are tightened in the end of Working mould 2 with the screw thread of pressure mould 4 has seal washer 6, it is ensured that sealing.

The end face of the contact with mold core B 5 of mold core A 3 is the concave surface 31 to central concave, the end that mold core B 5 is in contact with mold core A 3 Face is the convex surface 51 of the outwardly convex coordinated with 5 concave surface of mold core B 31.

When using, first, mold core A 3 is put into the hole A21 in the stepped hole of Working mould 2, mold core B 5 is put into pressure mould 4 In the B22 of hole, wherein, the concave surface of mold core A 3 is towards hole B22 directions；Secondly, pressure mould 4 is passed through into screw thread nested arrangements in Working mould In 2 hole B22, now, the concave surface 31 of mold core A 3 and the convex surface 51 of mold core B 5 are chimeric mutually, and end is tightened using the screw thread of pressure mould 4 41 are tightened, and Working mould 2 and pressure mould 4 coordinate even closer.

Steel wire is passed through from the through hole 1 in the mold core A 3 of Working mould 2 and the mold core B 5 of pressure mould 4, the steel wire walking in drawing process Wire drawing powder is brought into pressure mould 4（Pressure mould 4 is more direct than steel wire big 30) wire drawing powder by constantly conveying, extruding make work Mould 2 can preferably lubricate raising die life, while quality is guaranteed.

General principle of the present utility model and principal character has been shown and described above.The technical staff of the industry should Solution, the utility model is not restricted to the described embodiments, and this practicality is new for simply illustrating described in above-described embodiment and specification The principle of type, on the premise of the utility model spirit and scope are not departed from, the utility model also has various changes and modifications, These changes and improvements are both fallen within the range of claimed the utility model.The claimed scope of the utility model is by appended Claims and its equivalent thereof.
