Abstract
A kind of making carbon packing ring abnormity punch-forming mold, be made up of overcoat (1), upper press ring (2), lower pressure ring (3), core rod (4), gland (5), lower pressure ring (3) is positioned at overcoat (1) lower end, core rod (4) is positioned at overcoat (1) central authorities, upper press ring (2) is positioned at inside overcoat (1) upper end, and gland (5) pushes down upper press ring (2).It is have that structure is simple, reasonable in design, punching press is convenient, effectively avoid its radial variations, the one of the feature such as to improve the quality of products makes carbon packing ring abnormity punch-forming mold, it is the desired mold of current domestic making carbon packing ring, the requirement of different client to product quality can be met, be worth promoting.
Description
Technical field
The utility model relates to making carbon packing ring mechanical field, especially a kind of making carbon packing ring abnormity punch-forming mold.
Background technology
The purposes of carbon packing ring is quite extensive, it is applicable to the strong corrosive medium such as soda acid and solvent, also can not contaminated place for media such as high pressure valve plunger displacement pump, agitators, as industries such as food, medicine, papermaking, chemical fibres, it adopts flexible graphite belt or soft graphite braided packing, through the horizontal ring being pressed into different size.This ring has good resilience, chemical stability, can provide effective sealing function, deeply favors by user!
But in making carbon packing ring work, because of the defect of punch-forming mold, cause its product to change in axis, radial direction, especially radial change product---the ledge such as angle, depression of product, has had a strong impact on properties of product.Therefore, be necessary to make further improvements it.
Summary of the invention
The utility model just can effectively overcome above-mentioned technical disadvantages, there is provided have that structure is simple, reasonable in design, punching press is convenient, effectively avoid its radial variations, the one of the feature such as to improve the quality of products makes carbon packing ring abnormity punch-forming mold, it is the desired mold of current domestic making carbon packing ring, the requirement of different client to product quality can be met, be worth promoting.
Technical purpose of the present utility model is achieved in that a kind of making carbon packing ring abnormity punch-forming mold, is made up of overcoat, upper press ring, lower pressure ring, core rod, gland.Lower pressure ring is positioned at overcoat lower end, and core rod is positioned at overcoat central authorities, and upper press ring is positioned at inside outer set upper side, and gland pushes down upper press ring.
Five large parts of this described mould are single accessories, during work, are pressed down by gland by punch press, make pressure ring under upper press ring close contact;
Symmetrical projection is designed with inside described overcoat;
The outside of described upper press ring, lower pressure ring, gland is designed with symmetrical indent;
Described projection, indent are one to one;
Operation principle of the present utility model is: traditional carbon packing ring makes mould does not have projection and indent design, and because of product, mobility is too poor in process of production, causes its products radial to change greatly, the especially ledge such as angle, depression of product.Based on this, we to make mould carried out two greatly improve: design inside overcoat symmetrical projection, upper press ring, lower pressure ring, gland outside be designed with symmetrical indent, effectively overcome radial variations, ensure that shape of product sharp outline, compact density is even.
The beneficial effects of the utility model are: mold structure is simple, and easy to operate, stamping forming product quality is high, meets the demand of client.

Detailed description of the invention
By the following examples, the utility model is described in more detail, as long as but within the scope of main idea of the present utility model, be not limited in following examples.
A kind of making carbon packing ring abnormity punch-forming mold, is made up of overcoat (1), upper press ring (2), lower pressure ring (3), core rod (4), gland (5).Lower pressure ring (3) is positioned at overcoat (1) lower end, core rod (4) is positioned at overcoat (1) central authorities, upper press ring (2) is positioned at inside overcoat (1) upper end, and gland (5) pushes down upper press ring (2).
When making carbon packing ring:
1, soft graphite is wrapped in lower pressure ring (2) peripheral, is placed in overcoat (1) interior lower end;
2, core rod (4) is placed in overcoat (1) inner central;
3, overcoat (1) upper process is alignd with the indent on upper press ring (2), lower pressure ring (3), gland (5);
4, upper press ring (2) is placed in overcoat (1) upper end and core rod (4) gap;
5, gland (5) is placed in upper press ring (2) upper end;
6, punch press is aimed at gland (5) and is squeezed to overcoat (1) interior lower end and is close to lower pressure ring (3);
Above six steps complete a carbon packing ring punch forming process.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit protection domain of the present utility model with this; therefore: all equivalence changes done according to shape of the present utility model, structure, principle, all should be covered by within protection domain of the present utility model.
Claims (3)
1. one kind makes carbon packing ring abnormity punch-forming mold, be made up of overcoat (1), upper press ring (2), lower pressure ring (3), core rod (4), gland (5), it is characterized in that: lower pressure ring (3) is positioned at overcoat (1) lower end, core rod (4) is positioned at overcoat (1) central authorities, upper press ring (2) is positioned at inside overcoat (1) upper end, and gland (5) pushes down upper press ring (2).
