Abstract
The utility model discloses an extrusion die, which comprises a die body. A plurality of extrusion steps are arranged inside an inner cavity of the die body; a plurality of oil guide grooves for filling lubricating liquid are annularly arranged on the wall surfaces of the extrusion steps; and the oil guide grooves are connected with an oil supply system through oil guide pipelines. By ingeniously arranging the oil guide grooves on an original basis, it is possible to forcibly generate oil films when extrusion materials are extruded, thereby leading to indirect contact between the extrusion die and the extrusion materials, decreasing abrasion degree, prolonging service life, similarly ensuring dimensional precision of finished products and improving surface quality.
Description
Technical field
The utility model relates to a kind of extrusion die.
Background technology
Domestic existing extrusion die in use, all exists extrusion die directly to contact with extrded material at present, and this hard contact causes frictional force excessive, causes die wear to lose efficacy, and shorten service life.
The utility model content
The purpose of this utility model is to provide a kind of dies cavity degree of wear little, the extrusion die of long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of extrusion die, comprise die ontology, be provided with some extruding steps in the described die ontology inner chamber, it is characterized in that: ring is established some oil guide groove that lubricating fluid injects that are used on the wall of extruding step, and oil guide groove is connected with oil supply system by the Oil Guide pipeline.
Preferably, three extruding steps are set in the described dies cavity.
Preferably, described oil guide groove is three.
Preferably, two extruding steps are set in the described dies cavity.
Preferably, described oil guide groove is two.
Preferably, an extruding step is set in the described dies cavity.
Preferably, described oil guide groove is one.
Compared with prior art, the utility model has the advantages that: be provided with oil guide groove on the original basis cleverly, when extrded material is pushed, energy generation of forced oil film, make extrusion die directly contact with the extrded material surface is non-, the degree that reduces wear increases the service life, equally also guarantee the finished size precision, improved surface quality.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of extrusion die inner chamber of the utility model schematic diagram.
The specific embodiment
As Fig. 1 is an embodiment of a kind of extrusion die of the utility model, this extrusion die comprises die ontology 1, be provided with some extruding steps 2 in described die ontology 1 inner chamber, ring is established some oil guide groove 3 that lubricating fluid injects that are used on the wall 21 of extruding step 2, oil guide groove is connected with oil supply system by the Oil Guide pipeline 4 that passes die ontology 1, because extrusion die before all is to allow extrded material directly contact with extrusion die, can cause the wearing and tearing of mould.So will oil guide groove be set on the step in extruding, so abundant generation oil film makes that extrded material and extrusion die are non-directly to contact, and has protected extrusion die, prolongs its service life, and can improve the dimensional accuracy of finished product, improves surface quality.Specifically in the present embodiment,, the extruding step of varying number is set, the oil guide groove of respective numbers is set on the wall of extruding step according to the difference of extrded material; The utility model is specially adapted to the manufactured copper clad aluminum busbar; when the manufactured copper clad aluminum busbar; three extruding steps are set; on the wall of extruding step three oil guide groove are set, the super-pressure lubricating oil in the oil supply system enters into oil guide groove by the Oil Guide pipeline, when pushing; will produce oil film; can protect extrusion die, so just can make fully that copper clad aluminum wire and extrusion die are non-directly to contact, can guarantee the quality of copper clad aluminum wire simultaneously.The utility model is not only applicable to the manufacturing of copper clad aluminum wire, equally also is applicable to the manufacturing of other bimetallic products.
Claims (7)
