Abstract
The utility model relates to a stretching die, which comprises an upper die and a lower die matched with the upper die. The stretching die is characterized in that an annular soft sealing membrane is circumferentially arranged on the outer end surface of the upper die, the annular soft sealing membrane is tightly stuck to the outer end surface of the upper die, an oil supply hole is arranged in the space formed by the annular soft sealing membrane and the upper die, and the oil supply hole is communicated with an oil pipeline of the upper die; an annular soft sealing membrane is circumferentially arranged on the inner end surface of the lower die, the annular soft sealing membrane is tightly stuck to the inner end surface of the lower die, an oil supply hole is arranged in the space formed by the annular soft sealing membrane and the lower die, and the oil supply hole is communicated with an oil pipeline of the lower die. In the utility model, the annular soft sealing membranes are provided; when the stretching die is in work, the annular soft sealing membranes are squeezed to be broken by the pressure, and the lubricant oil inside the annular soft sealing membranes outflows, therefore, the work environment among the upper die, the lower die and the product is improved, the product quality is improved, and the service life of the upper die and the lower die is prolonged.
Description
Technical field
The utility model relates to a kind of stretching die.
Background technology
Stretching is the important form of goods processing, utilizing patrix that raw material is pressed in the counterdie forms, in pressing process, owing to produce strong impulsive force between upper die and lower die and the raw material, friction is serious each other, and caloric value is big, as does not have good lubricating property, cause quality of item to leave defective easily, reduce the service life of upper die and lower die simultaneously.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of service behaviour of improving between stretching die upper die and lower die and the goods, thereby improves the upper die and lower die stretching die in service life.
The technical solution of the utility model is: annular soft envelope film is circumferentially established in the patrix outer face, and annular soft envelope film and patrix outer face fit tightly, and establishes fuel feed hole in the space that annular soft envelope film and patrix form, and fuel feed hole and patrix oil line pipe are communicated with; The counterdie inner face is circumferentially established annular soft envelope film, and annular soft envelope film and counterdie inner face fit tightly, and establishes fuel feed hole in the space that annular soft envelope film and counterdie form, and fuel feed hole and counterdie oil line pipe are communicated with.
The soft envelope film of described annular is a screw type, and dish is located at the patrix outer face.
The soft envelope film of described annular is a screw type, and dish is located at the counterdie inner face.
The utility model has the advantages that: the utility model is provided with annular soft envelope film, and during work, annular soft envelope film is under pressure to be squeezed and breaks, and the lubricating oil of the inside flows out.Thereby improve the working environment between upper die and lower die and the goods, improve the service life of Products Quality and prolongation upper die and lower die.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that patrix, 2 is that annular soft envelope film, 3 is that fuel feed hole, 4 is counterdie among the figure.
The specific embodiment
The utility model is circumferentially established the ring-like soft envelope film 2 of screw type in patrix 1 outer face, fit tightly and form reserve between annular soft envelope film 2 and the patrix 1, and patrix 1 is positioned at reserve portion and establishes fuel feed hole 3, and the oil line pipe of fuel feed hole 3 and patrix 1 is communicated with.
The utility model is circumferentially established the ring-like soft envelope film 2 of screw type at counterdie 4 inner faces, fits tightly and form reserve between annular soft envelope film 2 and the counterdie 4, and counterdie 4 is positioned at reserve portion and establishes fuel feed hole 3, and the oil line pipe of fuel feed hole 3 and counterdie 1 is communicated with.
When the utility model uses, patrix 1 is pressed into raw material in the counterdie 4, the soft envelope film 2 of annular is squeezed and breaks, lubricating oil therefrom flows out lubricated, the soft envelope film 2 of annular of the present utility model is a screw type, purpose be make patrix 1, counterdie 4 each positions can both be fuel-displaced, improves greasy property to greatest extent.
Claims (3)
