Abstract
The utility model discloses a wire drawing die sleeve. The center of a column body die sleeve (2) is provided with a hole (1) for fixing a mold core. The utility model is characterized in that the bottom of the hole (1) is a cone (3) which is large inside and small outside. The utility model can not draw out and damage the mold core because of the inversion of a wire drawing machine, which greatly prolongs the service life of a wire drawing die.
Description
Technical field
The utility model relates to a kind of wire drawing die die sleeve.
Background technology
Wire drawing die is a kind of wire-drawing die.Wire drawing die is by die sleeve and places the core rod in the die sleeve hole to constitute.The hole of die sleeve central authorities carries out sintering with agglomerated powder after core rod is inserted fixes core rod.Existing hole is a cylinder.Said structure owing to often run into the counter-rotating of wire drawing machine, makes wire drawing give core rod an opposition in use, easily makes the die sleeve hole that the core rod agglomerate is drawn out together with core rod, causes the damage of wire drawing die, has reduced the life-span of product.
The utility model content
The purpose of this utility model solves die core of wire-drawing die exactly easily because of opposition withdraws from die sleeve, causes the damage of wire drawing die, has reduced the problem in the life-span of product.
The technical solution adopted in the utility model is: a kind of wire drawing die die sleeve, it is to be provided with the hole that is used for fixing core rod in cylindrical die sleeve central authorities, it is characterized in that described hole bottom is the big outer little cone in lining.
Adopt technique scheme, because the bottom of hole is a cone, when core rod be sintered powder sintering fixing after, form cone, when wire drawing machine reverses, wire drawing produces opposition to core rod, because the cone of the fixed formation of agglomerated powder and the extruding of die sleeve inwall, thereby stoped core rod to be pulled out with agglomerate.
The tapering angle of above-mentioned hole bottom cone is 10 degree.
In sum, the utility model beneficial effect is: because the bottom of the utility model die sleeve hole is a cone, make the extruding of agglomerate and die sleeve stop core rod oppositely to be pulled out, so the utility model can not carried the life-span of having led wire drawing die so greatly because of the wire drawing machine counter-rotating makes core rod pull out damage.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of wire drawing die die sleeve of the utility model, it is to be provided with the hole 1 that is used for fixing core rod in cylindrical die sleeve 2 central authorities, described hole 1 bottom is the big outer little cone 3 in lining.The tapering angle of hole 1 bottom cone 3 is 10 degree.
Claims (2)
1. wire drawing die die sleeve, it is to be provided with the hole [1] that is used for fixing core rod in cylindrical die sleeve [2] central authorities, it is characterized in that described hole [1] bottom is the big outer little cone [3] in lining.
2. die sleeve according to claim 1, the tapering angle that it is characterized in that described hole [1] bottom cone [3] are 10 degree.
