Abstract
Pressure wire drawing die sleeve relates to the wire drawing mould. Include pressure mould, drawing die, go up die sleeve and lower mold sleeve, going up the die sleeve and overlapping at lower mold sleeve upper portion outer wall and constitute detachable connections, the lower mold sleeve inner chamber is big -end -up's toper chamber, and the intracavity in lower mold sleeve is placed with the pressure mould to the drawing die, and the lower mold sleeve outer wall is equipped with the spiral cooling groove. The intracavity in lower mold sleeve is placed with the pressure mould to the drawing die, all constitutes taper fit with the lower mold sleeve inner chamber, can ensure the axiality of drawing die and pressure mould. The lower mold sleeve outer wall is equipped with the spiral cooling groove, and the cooling effect in spiral cooling groove obviously improves, and district's section of the spiral cooling groove longitudinal extension of establishing surrounds vertical length of drawing die, and the drawing die and the lower mold sleeve that enable the atress are showing the improvement radiating effect to show the reliability and the life that improve whole die sleeve.
Description
Technical field
This utility model is related to wire-drawing die, more particularly, to a kind of pressure wire drawing die cover.
Background technology
Existing wire drawing die cover has the disadvantage that：1. the pressure mould of die sleeve is matched somebody with somebody respectively with wire drawing die with Upper Die-sleeve and lower die-sleeve
Close, axiality coordinates not precisely, is easily caused wire drawing precision not high；2. typically only interval sets the lower die-sleeve bottom outer wall of wire drawing die cover
There are 2 cooling annular grooves, make die sleeve cooling effect poor, reduce its reliability and service life.
Chinese patent CN2351223Y discloses a kind of direct-cooling dismountable wire drawing die cover, by core rod, core retainer plate, overcoat, nut, swivel nut
Combine.After core rod is damaged, the die sleeve being made up of core retainer plate, overcoat, nut, swivel nut is reusable, saving steel.Using this
The die sleeve clamping, it is big to core rod pretightning force, reliable, concentricity height is installed, be conducive to improving drawing quality.Can direct water-cooling, have
High heat conductivility, service life can extend 3～4 times, and core retainer plate has ring-type louvre, can deform heat compared with fast diffusion steel wire, have
Beneficial to the various performances for improving steel wire.Jing is tested on middle drawing finishing die, every 4.2 tons of Mo Kela Φ 1.0mm steel wires.
The content of the invention
The purpose of this utility model is to provide a kind of pressure wire drawing die cover that can effectively overcome disadvantages mentioned above.
For achieving the above object, this utility model is adopted the following technical scheme that：
A kind of pressure wire drawing die cover, including pressure mould, wire drawing die, Upper Die-sleeve and lower die-sleeve；Its feature is：
Upper Die-sleeve is enclosed within lower die-sleeve external wall of upper portion and constitutes removable connection, and lower die-sleeve inner chamber is up big and down small taper
Chamber, wire drawing die is positioned over lower die-sleeve intracavity with pressure mould, and lower die-sleeve outer wall is provided with spiral cooling bath.
Further：
It is described removable to be connected as being spirally connected.
The section of spiral cooling bath longitudinal extension surrounds the longitudinal length of wire drawing die set by the lower die-sleeve.
Compared with the prior art, the beneficial effects of the utility model are as follows：
1., because lower die-sleeve inner chamber is up big and down small conical cavity, wire drawing die is positioned over lower die-sleeve intracavity with pressure mould,
Taper fit is constituted with lower die-sleeve inner chamber.So can ensure that the axiality of wire drawing die and pressure mould.
2., because lower die-sleeve outer wall is provided with spiral cooling bath, 2 cooling annulars are only interval with existing lower die-sleeve outer wall
Groove compares, and the cooling effect of spiral cooling bath is significantly improved, and if set spiral cooling bath longitudinal extension section surround
The firmly longitudinal length of wire drawing die, then the wire drawing die and lower die-sleeve that can make stress significantly improves radiating effect.So as to significantly improve
The reliability and service life of whole die sleeve.
Description of the drawings
Fig. 1 is the structural representation of conventional wire drawing die cover.
Fig. 2 is the structural representation of this utility model embodiment.
Specific embodiment
Referring to Fig. 1, existing conventional wire drawing die cover has the disadvantage that：1st, the pressure mould 11 of die sleeve is distinguished with wire drawing die 12
Coordinate with Upper Die-sleeve 13 and lower die-sleeve 14, axiality coordinates not precisely, is easily caused wire drawing precision not high；2nd, the lower mould of wire drawing die cover
Cover 14 bottom outer walls and be typically only interval with 2 cooling annular grooves 141, make die sleeve cooling effect poor, reduce its reliability
And service life.
Referring to Fig. 2, a kind of pressure wire drawing die cover described in this utility model embodiment, including pressure mould 21, wire drawing die 22, on
Die sleeve 23 and lower die-sleeve 24；Its feature is：
Upper Die-sleeve 23 is enclosed within the external wall of upper portion of lower die-sleeve 24 and composition is spirally connected, and the inner chamber of lower die-sleeve 24 is up big and down small taper
Chamber, wire drawing die 22 is positioned over the intracavity of lower die-sleeve 24 with pressure mould 21, and the outer wall of lower die-sleeve 24 is provided with spiral cooling bath 241.The spiral shell
The section of the rotation longitudinal extension of cooling bath 241 surrounds the longitudinal length of wire drawing die 22.
Claims (3)
1. pressure wire drawing die cover, including pressure mould, wire drawing die, Upper Die-sleeve and lower die-sleeve；It is characterized in that：
Upper Die-sleeve is enclosed within lower die-sleeve external wall of upper portion and constitutes removable connection, and lower die-sleeve inner chamber is up big and down small conical cavity, is drawn
Silk mould is positioned over lower die-sleeve intracavity with pressure mould, and lower die-sleeve outer wall is provided with spiral cooling bath.
2. pressure wire drawing die cover as claimed in claim 1, it is characterised in that：It is described removable to be connected as being spirally connected.
3. pressure wire drawing die cover as claimed in claim 1, it is characterised in that：Spiral cooling bath longitudinal extension set by the lower die-sleeve
Section surround the longitudinal length of wire drawing die.
