Abstract
The utility model belongs to powder metallurgy die field, and in particular to mould in a kind of high voltage bearing compound powder metallurgy die, it is characterised in that：Mould includes double-deck cylindrical shell in the high voltage bearing compound powder metallurgy die；Internal cavity is provided with the double-deck cylindrical shell, high pressure resistant core rod is provided with the internal cavity；Blowing chamber is provided with the high pressure resistant core rod；The double-deck cylindrical shell is fastenedly connected with the high pressure resistant core rod.The utility model is high pressure resistant, is not easy damage of splitting, therefore service life is grown, cost-effective.
Description
Technical field
The utility model belongs to powder metallurgy die field, specifically discloses a kind of high voltage bearing compound powder metallurgy mould
Mould in tool.
Background technology
Powder metallurgy is mainly suitable for automobile industry, equipment manufacture, metal industry, Aero-Space, war industry, instrument
The spare and accessory parts production and research in the fields such as instruments and meters, hardware ＆ tools, electronic appliance, product include bearing, gear, carbide cutter tool
Tool, mould, friction goods etc.；In military enterprise, heavy weaponry such as armor-piercing bullet, torpedo etc., the brake such as aircraft tank
Pair is both needed to produce using PM technique；Automobile metal powder sintered parts have turned into as Chinese Powder Metallurgy Industry maximum in recent years
Market, about 50% auto parts and components are powder metallurgy parts.
The single material of mould generally use is made in powder metallurgy die on the market, under the operating environment of high pressure easily
Split so that the working life of whole set of die is not grown, and then improves the cost input of enterprise.
Utility model content
Technical problem to be solved in the utility model is to provide mould in a kind of high voltage bearing compound powder metallurgy die.
The utility model for realize solution that its technique effect uses for：
Mould in a kind of high voltage bearing compound powder metallurgy die, it is characterised in that：The high voltage bearing compound powder smelting
Mould includes double-deck cylindrical shell in golden mould；Internal cavity is provided with the double-deck cylindrical shell, is set on the internal cavity
It is equipped with high pressure resistant core rod；Blowing chamber is provided with the high pressure resistant core rod；The double-deck cylindrical shell and the high pressure resistant core rod
It is fastenedly connected.
Preferably, double-deck cylindrical shell provided by the utility model and high pressure resistant core rod are fastenedly connected by welding procedure.
Preferably, the material that double-deck cylindrical shell provided by the utility model uses is No. 45 steel.
Preferably, the material that high pressure resistant core rod provided by the utility model uses is tungsten carbide.
The beneficial effects of the utility model are：By welding the higher high pressure resistant core rod of hardness in double-deck cylindrical shell,
So that the high-voltage resistance capability of middle mould greatly improves.
To make the technical solution of the utility model and technique effect clearer, clear and definite, below in conjunction with Figure of description and
Embodiment elaborates to mould in high voltage bearing compound powder metallurgy die disclosed in the utility model.
Brief description of the drawings
Fig. 1：Mould schematic diagram in high voltage bearing compound powder metallurgy die disclosed in the utility model.
Identifier declaration：1- bilayer round platform shells, the high pressure resistant core rods of 2-, 3- blowing chambers.
Embodiment
Fig. 1 is refer to, a kind of high voltage bearing compound powder metallurgy die is disclosed in the utility model preferred embodiment
Middle mould, mould includes double-deck cylindrical shell 1 in the high voltage bearing compound powder metallurgy die；It is provided with double-deck cylindrical shell 1
Internal cavity, high pressure resistant core rod 2 is provided with internal cavity；Blowing chamber 3 is provided with high pressure resistant core rod 2；Double-deck cylindrical shell 1
It is fastenedly connected with high pressure resistant core rod 3.
Specifically, in the utility model preferred embodiment, double-deck cylindrical shell 1 and high pressure resistant core rod 2 pass through Welder
Skill is fastenedly connected, and the material that double-deck cylindrical shell 1 uses is No. 45 steel, and the material that high pressure resistant core rod 2 uses is tungsten carbide.
In high voltage bearing compound powder metallurgy die provided by the utility model mould with it is other in powder metallurgy die
Part cooperating is compressing by metal dust.
Seen from the above description, the higher high pressure resistant core rod of hardness is welded with the utility model in double-deck cylindrical shell,
So that the high-voltage resistance capability of middle mould greatly improves, damage of splitting, therefore the utility model can be not easy under operations involving high pressure environment
Service life is grown, cost-effective.
Preferred embodiment of the present utility model is elaborated above in association with Figure of description, it should explanation
It is that the scope of protection of the utility model includes but is not limited to above-described embodiment；Concrete structure disclosed in Figure of description is also only
It is preferred embodiment of the present utility model, the technical staff in the field can also develop other embodiment on this basis,
Any simple deformation or equivalent substitution for not departing from the utility model innovative idea, is covered by the utility model, belongs to this reality
With new protection domain.
