Abstract
The utility model relates to a straight line type wire-drawing die adopting a hard alloy die core, comprising a die sleeve and the die core, wherein the die core is tightly embedded in the die sleeve; the die core adopts a hard alloy member; an inner hole of the die core is formed by connecting a flare opening, an inlet cone, a deformed cone, a sizing belt and an outlet angle; and a hard coating is coated on the inner surface of the die core. In the straight line type wire-drawing die, the structure is simple, the use is convenient, the die core is high in strength so as to be difficultly broken, the wire-drawing accuracy is high, and the surface is smooth.
Description
Technical field
The utility model relates to wire drawing die, is specially a kind of linear wire drawing die that adopts the carbide alloy core rod.
Background technology
At present, when draw metal silk or metal bar, generally all can use wire drawing die, wire drawing die of the prior art is made up of a die sleeve and the cylindrical core rod that is embedded in wherein by trapezoidal endoporus, the interior hole shape of core rod is a full arc shape, promptly do bus with arcuate line segment, rotate around the axle center 360 ° and form tubaeform, because this hole shape in high speed drawing steel wire process, is easy to generate stress and concentrates, the machining accuracy of endoporus, flatness, fineness also grinds because of manual, can not reach higher level, and the core rod of traditional wire drawing die is easy to fragmentation, and service life is very short.
The utility model content
The technical problem that the utility model solved is to provide a kind of linear wire drawing die that adopts the carbide alloy core rod, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of linear wire drawing die that adopts the carbide alloy core rod, comprise die sleeve and core rod, described core rod tightly is embedded in the die sleeve, it is characterized in that, described core rod adopts the carbide alloy member, and the endoporus of core rod is linked to each other by horn mouth, approach cone, distortion awl, calibrating strap and the angle of outlet and forms.
In the utility model, the inner surface of described core rod coats hard coat, and this hard coat comprises titanium carbide, titanium nitride, aluminium oxide hard formation or the compound hard formation that adopts chemical vapour deposition technique to apply.
In the utility model, the endoporus of core rod is shape linearly, comprise horn mouth, approach cone, distortion awl, calibrating strap and the angle of outlet, wherein the height of calibrating strap and work tapering can choose at random as required, die sleeve adopts carbon steel, core rod adopts the carbide alloy manufacturing, and both distinguish after the Precision Machining, makes by low temperature edge cover again.
Beneficial effect: the utility model is simple in structure, and is easy to use, and the intensity height of core rod is difficult for fragmentation, and wire drawing precision height, any surface finish.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of linear wire drawing die that adopts the carbide alloy core rod, comprise die sleeve 1 and core rod 2, described core rod 2 tightly is embedded in the die sleeve 1, it is characterized in that, described core rod 2 adopts the carbide alloy member, and the endoporus of core rod 2 is linked to each other by horn mouth 3, approach cone 4, distortion awl 5, calibrating strap 6 and the angle of outlet 7 and forms.
In the present embodiment, the inner surface of described core rod 2 coats hard coat, and this hard coat comprises titanium carbide, titanium nitride, aluminium oxide hard formation or the compound hard formation that adopts chemical vapour deposition technique to apply.
In the present embodiment, calibrating strap 6 height and the work tapering of core rod 2 can choose at random as required, and die sleeve 1 adopts carbon steel, and core rod 2 adopts the carbide alloy manufacturing, and both distinguish after the Precision Machining, make by low temperature edge cover again.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
