Abstract
The invention relates to a stamping die. The stamping die comprises an upper die and a lower die and is characterized in that the bottom of the upper die is provided with a punch while the work surface of the lower die and the surface of the punch are coated with a layer of hard wear-resistant coating, the wear-resistant coating is DLC film, titanium nitride coating, titanium carbonitride coating, titanium aluminum nitride coating or chromium nitride coating. The hardware stamping die comprises the upper die and the lower die, the bottom of the upper die is provided with a punch while the surface of the punch are coated with a layer of hard wear-resistant coating, the wear-resistant coating has characteristics of high hardness, wear-resistant, corrosion resistance performance and dry lubricity, not easy to fall off, environmental protection, the hardness, wear-resistant, corrosion resistance performance for the punch can be improved, the punch cannot be damaged easily, the die repairing times is reduced and the service life of the die is prolonged.
Description
Technical field
The present invention relates to a kind of diel.
Background technology
Metal stamping die is in the industrial production, with various forcing press and the specific purpose tool be contained on forcing press, by pressure, metal material is made the part of required form or the instrument of goods.Existing metal stamping die is in shaping production process; because the hardness of mold materials is not high enough; wearability is not high yet; drift and counterdie often can be bruised, weigh wounded, serious wear, and the spoilage of mould is higher; service life is short; although can reduce die surface damage by improving mold materials, effect is undesirable, can not meet the demand that people are growing.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of diel.
Described a kind of diel, include upper die and lower die, it is characterized in that the bottom of described patrix is provided with drift, the working surface of counterdie and the surface of drift are all coated with one deck hard wear-resistant coating, and described wear-resistant coating is DLC film, film is admired in nitrogenize, film is admired in carbon nitrogenize, aluminium film is admired in nitrogenize or chromium nitride film.
Described a kind of diel, is characterized in that the thickness of described wear-resistant coating is 1-10 nanometer.
Described a kind of diel, is characterized in that the thickness of described wear-resistant coating is 1-3 nanometer.
Metal stamping die provided by the invention, it includes upper die and lower die, the bottom of patrix is provided with drift, and the surface of drift is coated with one deck hard wear-resistant coating, and hard wear-resistant coating has the features such as hardness is high, wear-resisting, corrosion-resistant, dry lubrication, difficult drop-off, environmental protection, improves hardness, wearability, the corrosion resistance of drift, drift is not easily sustained damage, reduce the number of times that repairs a die, extend the mold use life-span.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
Patrix 1 and counterdie 2 are the present invention includes, the bottom of patrix 1 is provided with drift 3, the surface of drift 3 is coated with one deck densification, evenly and the hard wear-resistant coating 4 be combined with drift 3, the working surface of counterdie 2 is also coated with one deck hard wear-resistant coating 4, wear-resistant coating 4 can be DLC film, nitrogenize is admired film, carbon nitrogenize is admired film, nitrogenize is admired aluminium film or chromium nitride film, the wear-resistant coating 4 of drift 3 and the wear-resistant coating 4 of counterdie 2 can the same also can be different, wherein, DLC film is containing adamantine amorphous carbon-film, be similar to diamond and there is again good tribological property, make the case hardness of drift 3 high, wear-resisting, any surface finish, coefficient of friction is low to moderate 0.10, and there is good corrosion resistance and anti-caking, the easy demoulding, nitrogenize film of admiring has heat-resisting quantity, about 600 degree, also has wear-resisting, the corrosion resistance of height, extends the mold use life-span, carbon nitrogenize is admired containing carbon element in film, and hardness is high, and slickness is good, makes drift high temperature resistant, wear-resisting, corrosion-resistant, and has resistance to viscosity, nitrogenize is admired the effect containing aluminium in aluminium film, there is high temperature oxidative resistance, about 800 degree, also under dry type or high-speed condition, preferably performance can be played to drift 3, according to the kind of mould, the film condition of material setting the best, the mold use life-span can be improved, chromium nitride film has heat-resisting quantity and mar proof, has very high dissolubility resistent to non-ferrous metal.Thus hard wear-resistant coating 4 of the present invention has the features such as hardness is high, wear-resisting, corrosion-resistant, dry lubrication, difficult drop-off, environmental protection, improve hardness, wearability, the corrosion resistance of mould, mould is not easily sustained damage, reduces the number of times that repairs a die, extend the mold use life-span.
The thickness of wear-resistant coating 4 is 1-10 nanometer, and be preferably 1-3 nanometer, thickness can be 1 nanometer, 2 nanometers, 3 nanometers, 6 nanometers, 10 nanometers etc., and can certainly be other numerical value, thickness be little, can not affect the size of mould.
Metal stamping die provided by the invention, it includes upper die and lower die, the bottom of patrix is provided with drift, and the surface of drift is coated with one deck hard wear-resistant coating, and hard wear-resistant coating has the features such as hardness is high, wear-resisting, corrosion-resistant, dry lubrication, difficult drop-off, environmental protection, improves hardness, wearability, the corrosion resistance of drift, drift is not easily sustained damage, reduce the number of times that repairs a die, extend the mold use life-span.
Claims (3)
1. a diel, include upper die and lower die, it is characterized in that the bottom of described patrix is provided with drift, the working surface of counterdie and the surface of drift are all coated with one deck hard wear-resistant coating, and described wear-resistant coating is DLC film, film is admired in nitrogenize, film is admired in carbon nitrogenize, aluminium film is admired in nitrogenize or chromium nitride film.
