Abstract
The utility model discloses a die punch, including the body, its characterized in that: the body is cylindrically, and the body diameter is 20 mm ~35 mm, this external upward coating has two -layer stereoplasm wearing layer, is chromium nitride coating and titanium nitride coating in proper order, the chromium nitride coating set up in the body with between the titanium nitride coating, the thickness of chromium nitride coating is 3 mu m~4.5 mu m, the thickness of titanium nitride coating is 3.5 mu m~4.5 mu m. The utility model discloses in set up two -layer stereoplasm wearing layer outside the body, the thickness of stereoplasm wearing layer is chosen moderately simultaneously, can guarantee the hardness and the wearability of body, can also guarantee manufacturing cost.
Description
Technical field
The utility model relates to a kind of dieparts, particularly relates to a kind of mold and punching head.
Background technology
During metal stamping die in the industrial production, with various forcing press and be contained in the specific purpose tool 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, high cost, effect is also not ideal enough.
Summary of the invention
The utility model object is to provide a kind of mold and punching head, by using this structure, improves hardness and the wearability of mold and punching head.
For achieving the above object, the technical solution adopted in the utility model is: a kind of mold and punching head, comprise body, described body is cylindrical, and body diameter is 20 ㎜ ~ 35 ㎜, and described body is outside upper is coated with two-layer hard wear-resistant layer, be followed successively by chromium nitride coating and titanium nitride coating, described chromium nitride coating is arranged between described body and described titanium nitride coating, and the thickness of described chromium nitride coating is 3 μm ~ 4.5 μm, and the thickness of described titanium nitride coating is 3.5 μm ~ 4.5 μm.
In technique scheme, the thickness of described chromium nitride coating is 3.5 μm.
In technique scheme, the thickness of described titanium nitride coating is 4 μm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. in the utility model, two-layer hard wear-resistant layer is set outside body, be respectively chromium nitride coating and titanium nitride coating, the thickness of the convex coating of chromium nitride is 3.5 μm, titanium nitride coating thickness is 4 μm, compared with structure in the past, the structure in the past not arranging hard wear-resistant layer can only punching press about 10000 times, the titanium nitride coating of 4 μm is set, can punching press 20000 ~ 30000 times, also arrange chromium nitride to protrude simultaneously, further increase wearability and hardness, the basis that titanium nitride coating is set increases punching press about 30000 times, simultaneously, the thickness of titanium nitride coating is 4 μm, the thickness of chromium nitride coating is 3.5 μm, thickness is moderate, if thickness is thicker, the time that needs process in nitriding furnace is longer, cost is higher, if thickness is excessively thin, then hardness and wearability do not reach requirement, therefore, select the hard wear-resistant layer hardness of thickness in the utility model strong, wearability is good,
2. the utility model structure is simple, is easy to realize.
Accompanying drawing explanation
Fig. 1 is the structural representation of body in the utility model embodiment one;
Fig. 2 is the cross section structure schematic diagram of body in the utility model embodiment one.
Wherein: 1, body; 2, chromium nitride coating; 3, titanium nitride coating.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one: shown in Fig. 1,2, a kind of mold and punching head, comprise body 1, described body 1 is outside upper is coated with two-layer hard wear-resistant layer, be followed successively by chromium nitride coating 2 and titanium nitride coating 3, described chromium nitride coating 2 is arranged between described body 1 and described titanium nitride coating 3, and the thickness of described chromium nitride coating 2 is 3.5 μm, and the thickness of described titanium nitride coating 3 is 4 μm.
In the utility model, body 1 is cylindrical, and body 1 diameter is 20 ㎜ ~ 35 ㎜, preferably 30 ㎜, on the body 1 of this diameter, thickness setting is the titanium nitride coating 3 of the chromium nitride coating 2,4 μm of 3.5 μm, in order to ensure hardness and the wearability of drift, ensures its production cost simultaneously.In the present embodiment, chromium nitride coating 2 adopts 3.5 μm, and titanium nitride coating 3 adopts 4 μm, can ensure that the drift of this diameter can punching press 50000 times ~ 60000 times, if only adopt single hard wear-resistant layer, then punching press number of times is then minimum reduces by half, meanwhile, if the thickness of coating is thicker, cost is higher, and in nitriding furnace, needing the time to be processed longer, cost is higher, wastes energy.
