Abstract
A press toll comprises a die body (1) and a tool chamber (2); a corrosion-resistant layer (3) is arranged between the die body (1) and the die chamber (2); the die chamber (2) is cylindrical; the corrosion-resistant layer (3) is a circle set; and the corrosion-resistant layer (3) is closely matched on the inner surface of the die chamber (2). The press die has the advantages that the materials of silicon carbide ceramics and the like are adopted to prepare the corrosion-resistant layer; as the silicon carbide ceramics has good corrosion resistance, the die body is effectively prevented from being corroded by corrosive powders such as acid, alkali or strong oxidizing property and the like, or granular materials; and the service life of the die is improved. The silicon carbide ceramics has stable chemical property, good chemical corrosion resistance, does not cause pollution to the original press materials, has high rigidity and high temperature resistance, and prolongs the service life of the die.
Description
Technical field
The utility model relates to a kind of diel, specifically is a kind of being used for corrosivity powder such as acid, alkali or strong oxidizing property or particulate material punching press in flakes or the mould of shape such as column.
Background technology
As shown in Figure 1, existing be used for corrosivity powder such as acid, alkali or strong oxidizing property or particulate material punching press in flakes or the mould of ring-type all be to adopt mould steel or carbide alloy to make mostly, when punching press, contact-making surface with corrosivity powder such as acid, alkali or strong oxidizing property or particulate material is easy to corrosive wear, causes mould can't continue to use.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of and effectively prevents by the diel of corrosivity powder such as acid, alkali or strong oxidizing property or particulate material corrosion.
For solving the problems of the technologies described above, the diel that the utility model provides comprises die ontology and die cavity, is provided with anti-corrosion layer between described die ontology and the die cavity.
After adopting above structure, the utility model diel compared with prior art has the following advantages:
The good corrosion resistance of silicon carbide ceramics adopts material making anti-corrosion layers such as silicon carbide ceramics, owing to can prevent effectively that die ontology is by corrosivity powder or particulate material corrosion such as acid, alkali or strong oxidizing property, the service life of having improved mould.The silicon carbide ceramics chemical property is stable, and chemical resistance is good, can not pollute former stamping material.Silicon carbide ceramics hardness is high and high temperature resistant, has prolonged the service life of mould.
As improvement, described die cavity can be column type, and described anti-corrosion layer can be round casing, and described anti-corrosion layer is a tight fit on the inner surface of die cavity.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of existing diel.
Fig. 2 is the sectional structure schematic diagram of the utility model diel.
Wherein, 1, die ontology; 2, die cavity; 3, anti-corrosion layer.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 2, the utility model diel comprises die ontology 1 and die cavity 2, is provided with anti-corrosion layer 3 between described die ontology 1 and the die cavity 2.Described die cavity 2 is cylindrical, and described anti-corrosion layer 3 is the circle cover, and described anti-corrosion layer 3 is a tight fit on the inner surface of die cavity 2.
Claims (2)
1, a kind of diel comprises die ontology (1) and die cavity (2), it is characterized in that: be provided with anti-corrosion layer (3) between described die ontology (1) and the die cavity (2).
2, diel according to claim 1 is characterized in that: described die cavity (2) is for cylindrical, and described anti-corrosion layer (3) is the circle cover, and described anti-corrosion layer (3) is a tight fit on the inner surface of die cavity (2).
