Abstract
The invention relates to the technical field of dies, in particular to a hardware stamping die. The hardware stamping die comprises an upper die body (1) and a lower die body (2). A punch pin (3) is arranged at the bottom of the upper die body (1). The working surface of the lower die body (2) and the surface of the pinch pin (3) are respectively coated with a hard abrasion-resistant coating (4). DLC films or titanium nitride films or titanium carbonitiride films or titanium and aluminum nitride films or chromium nitride films serve as the hard abrasion-resistant coatings (4). The hard abrasion-resistant coatings have the advantages of being high in rigidity, abrasion to abrasion and corrosion, high in lubricity and the like, is not prone to falling, and is environmentally friendly. Hardness, abrasion resistance and corrosion resistance of the punch pin are improved, the punch pin can be prevented from being easily damaged, the number of die repair times is reduced, and the service life of the die is prolonged.
Description
Technical field
The present invention relates to technical field of mold, refer in particular to metal stamping die.
Background technology
Metal stamping die is in industrial production, with various forcing presses and be contained in the specific purpose tool on forcing press, by pressure, metal material is made to the part of required form or the instrument of goods.Existing metal stamping die is in moulding 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 growing demand of people.
Summary of the invention
Object of the present invention be exactly the deficiency existing for prior art and provide that a kind of hardness is high, wearability is high, the metal stamping die of corrosion-resistant, long service life.
To achieve these goals, the technical solution used in the present invention is: metal stamping die, it includes upper die and lower die, 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, nitrogenize admire film, carbon nitrogenize admire film, nitrogenize admire aluminium film or chromium nitride film.
The working surface of described counterdie is also coated with one deck hard wear-resistant coating.
The thickness of described wear-resistant coating is 1-10 nanometer.
The preferred 1-3 nanometer of thickness of described wear-resistant coating.
Beneficial effect of the present invention is: 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, hardness, wearability, the corrosion resistance of raising drift, make drift be difficult for sustaining damage, reduce the number of times that repairs a die, extend the service life of mould.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of counterdie of the present invention.
detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated, see Fig. 1, shown in 2, 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 with the hard wear-resistant coating 4 of drift 3 combinations, 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, the nitrogenize film of admiring, the carbon nitrogenize film of admiring, nitrogenize admire aluminium film or chromium nitride film, the wear-resistant coating 4 of drift 3 and the wear-resistant coating 4 of counterdie 2 can be the same also can be different, wherein, DLC film is to contain 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 easily demoulding, the nitrogenize film of admiring has heat-resisting quantity, and approximately 600 degree also have wear-resisting, the corrosion resistance of height, extend the service life of mould, carbon nitrogenize is admired in film containing carbon element, and hardness is high, and slickness is good, makes drift 3 high temperature resistant, wear-resisting, corrosion-resistant, and has resistance to viscosity, the nitrogenize effect that contains aluminium in aluminium film of admiring, has high temperature oxidative resistance, and approximately 800 degree also can be brought into play preferably performance to drift 3 under dry type or high-speed condition, set best film condition, the service life that can improve mould according to the kind of mould, material, chromium nitride film has heat-resisting quantity and mar proof, and non-ferrous metal is had to very high dissolubility resistent.Thereby hard wear-resistant coating 4 of the present invention the has 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, make mould be difficult for sustaining damage, reduce the number of times that repairs a die, extend the service life of mould.
The thickness of wear-resistant coating 4 is 1-10 nanometer, is preferably 1-3 nanometer, and thickness can be 1 nanometer, 2 nanometers, 3 nanometers, 6 nanometers, 10 nanometers etc., can certainly be other numerical value, and thickness is little, can not affect the size of mould.
Certainly, the above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
Claims (3)
