Abstract
The utility model relates to a hard alloy wire-drawing die which comprises a die body made of chrome steel; a hard alloy layer is arranged in the die body; the die body and the hard alloy layer are mounted in an interference fit manner; and an upper molding cavity, a necking cavity and a lower molding cavity are formed in the hard alloy layer. The hard alloy wire-drawing die provided by the utility model has the advantages that a hard alloy layer is arranged in the die body, so that the cost of a die is reduced, the wearing resistance of the die is good, and the service life is long.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of sintered carbide wire drawing die, belongs to five metals processing mold technical field.
Background technology
The drawing die of prior art adopts the chromium steel material monolithic to be processed to form usually, and it is drawn under the huge frictional force effect of type, easily causes wearing and tearing, makes the mold use life-span shorter.
Along with appearance and the use of carbide alloy, the drawing die that adopts carbide alloy to make is also arranged, still, the cost of such mould is higher, is unfavorable for the marketing use.
Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of structure improved sintered carbide wire drawing die that has, to overcome described defective of the prior art.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide that a kind of cost is low, wearability good and the sintered carbide wire drawing die of long service life.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of sintered carbide wire drawing die, and it comprises the die ontology of a chromium steel material; Be provided with one deck hard alloy layer in described die ontology; Described die ontology and hard alloy layer adopt interference fit to install; Form upper forming cavity, necking down chamber and compacted under chamber in described hard alloy layer.
Sintered carbide wire drawing die of the present utility model further is set to: described die ontology is the convex shape structure.
Sintered carbide wire drawing die of the present utility model further is set to: the diameter of described upper forming cavity is less than the diameter in compacted under chamber.
Compared with prior art, the utlity model has following beneficial effect: sintered carbide wire drawing die of the present utility model is by arranging a hard alloy layer in the die ontology of chromium steel material, thereby reduced the cost of mould, and made the wearability of mould good, long service life.
Description of drawings
Fig. 1 is the sectional drawing of sintered carbide wire drawing die of the present utility model.
The specific embodiment
See also shown in Figure of description 1, the utility model is a kind of sintered carbide wire drawing die, and it comprises a die ontology 1, and this die ontology 1 is made by the chromium steel material, and it is the convex shape structure.
The greatest improvement part of sintered carbide wire drawing die of the present utility model is: be provided with one deck hard alloy layer 2 in described die ontology 1.Described die ontology 1 and hard alloy layer 2 adopt interference fit to install.Forming cavity 21 in the interior formation of described hard alloy layer 2, necking down chamber 22 and compacted under chamber 23.Wherein, the diameter of described upper forming cavity 21 is less than the diameter in compacted under chamber 23.Described necking down chamber 22 can make expanded material compressed stretching gradually.
Sintered carbide wire drawing die of the present utility model is by arranging a hard alloy layer 2 the die ontology 1 of chromium steel material is interior, thereby reduced the cost of mould, and makes the wearability of mould good, long service life.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., within all should being included in the protection domain of this creation.
Claims (3)
