Abstract
The utility model discloses a rivet mould. The rivet mould comprises a mould body, wherein the centre of the mould body is provided with a mould cavity matched with the shape of the rivet; and the inner wall of the mould cavity is provided with a hard alloy layer. The rivet mould is simple in structure and reasonable in design. By designing the hard alloy layer, the service performance of the rivet mould is enhanced, the service life of the rivet mould is prolonged and the production cost of enterprises is reduced.
Description
Technical field:
The utility model relates generally to technical field of mold, relates in particular to a kind of rivet die.
Background technology:
Mould is to be used for the instrument of formed article, and this instrument is made up of various parts, and different dies is made up of different parts.It mainly realizes the processing of article profile through the change of institute's moulding material physical state.
Rivet die is in preparation rivet process, and its die cavity is worn easily, and service life is short, has improved the production cost of enterprise.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of rivet die of long service life to be provided.
The utility model is realized through following technical scheme:
A kind of rivet die; It is characterized in that: include mold, said mold center is provided with the die cavity with the rivet external appearance matching, and said mold is set with overcoat outward; Be formed with annular chamber between said overcoat and the mold, said outer inlet opening and the apopore that is provided with the annular chamber conducting that put; The inwall of said die cavity is provided with hard alloy layer.
A kind of rivet die is characterized in that: the thickness of said hard alloy layer is 1-3 ㎜.
Carbide alloy has a series of premium properties, particularly its high rigidity and wearability such as hardness height, wear-resisting, intensity and toughness is better, heat-resisting, corrosion-resistant, even under 500 ℃ temperature, also remain unchanged basically, in the time of 1000 ℃, still has very high hardness.Therefore, the hard alloy layer in the utility model is to the utlity model has good protection effect.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, through the design of hard alloy layer, strengthened the serviceability of the utility model, prolonged the service life of the utility model, reduced the production cost of enterprise.
