Tool.
Background technology
Spring steel wire used in being engaged in the technological requirement of spring production must have very good antifatigue creep properties
Can, i.e., kept after spring steel wire wound into spring in exhaustion creep experiment and routine use is carried out its good mechanical performance and
Size, will not occur a problem that camber of spring, shorten because of long-term use of.
The cold-drawing process of steel wire, it is the wire drawing by steel wire from definite shape and size by the tractive force of equipment reel
Pulled out in die hole, so as to produce the merchant wire of various cross dimensions, due to finished size compared with scantling diameter difference compared with
Greatly, so thicker material could be drawn into thinner product by the drawing of multi-pass by being typically necessary, and per drawing together
Special ratios between the outlet steel wire diameter d and entrance steel wire diameter d0 of silk mould, referred to as passage draft or shout secondary
Compression ratio.In existing steel wire production process, the Reduction per draft of spring steel wire is generally 12-23% during the design of wire-drawing die
, final pass compression ratio is generally no greater than 17%.But such set causes what existing drawing process was produced
Spring steel wire situation bad through often there is antifatigue croop property after wound into spring.
Utility model content
The purpose of this utility model is to solve deficiency of the prior art, there is provided one kind is reduced during Production for Steel Wire
Workload and the activity duration, while enhance the antifatigue croop property of steel wire, what is improved product quality and production efficiency changes
The wire-drawing die of kind steel wire exhaustion creep.
Technical scheme：A kind of wire-drawing die for improving steel wire exhaustion creep described in the utility model, including die main body,
Die main body is cylindrical structure, inner core is provided with the center of die main body, inner core is from top to bottom successively by inlet region, lubrication
Area, compressional zone, sizing area and outlet area composition, inlet region, lubrication area, compressional zone, sizing area and outlet area are coaxial, and sizing area is
Cylindrical structure, inlet region, lubrication area, compressional zone and outlet area are frustum cone structure, the bottom surface of inlet region and lubrication area it is upper
Basal diameter is identical, and it is identical with the upper bottom surface diameter of compressional zone to lubricate the bottom surface in area, lubricates bottom surface, the horizontal stroke of sizing area in area
Section and the upper bottom surface diameter all same of outlet area, the Reduction per draft of die main body are 20-24%, the calculating of Reduction per draft
Formula is (1- (d/d0)2) × 100%, wherein d are the upper surface diameter of outlet area, and d0 is the upper surface diameter of compressional zone.
Further, the material of die main body is hard alloy or diamond.
The utility model has advantages below compared with prior art：From the passage pressure of technique source adjustment die main body 6
Shrinkage is 20-24%, and the antifatigue croop property for the steel wire produced effectively is improved, and enhances the antifatigue creep of steel wire
Performance, improve product quality and production efficiency, while reduce the workload during Production for Steel Wire and activity duration.
