Description
Technical field
The present invention relates to mould manufacture field, more particularly to a kind of material fabrication process of cold-working mould.
Background technology
SDC99 high strength and toughness cold working mould steel has extremely strong toughness and intensity, is the ideal material for preparing cold-working mould.
But the anti-wear performance of SDC99 high strength and toughness cold workings mould steel itself is poor, so as to cause SDC99 high strength and toughness cold working mould steel forgings
The anti-wear performance for the cold-working mould made is relatively low, reduces the cold-working mold use life-span.
The content of the invention
In order to solve the above technical problems, a kind of material fabrication process of cold-working mould proposed by the present invention, its particular technique
Scheme is as follows：
A kind of material fabrication process of cold-working mould, it in turn includes the following steps：
Blanking：Prepare bar-shaped base material, the material of the bar-shaped base material is SDC99 high strength and toughness cold working mould steel；
High-abrasive material coats：One layer of wear resistant friction reducing coating is coated on the surface of bar-shaped base material to obtain bar-shaped blank, it is described
Wear resistant friction reducing coating is Cr base wear resistant friction reducing coatings CrTiAlN；
Heat treatment：Bar-shaped blank is heated using heating furnace, to remove its stress.
In a specific embodiment, the mass component percentage of the SDC99 high strength and toughness cold workings mould steel is： C：
0.9%, Si：1.03%, Mn：0.2%, Cr：10.2%, Mo：1.9%, V：0.92%, Ni：0.12%, surplus Fe.It is described
The mass component percentage of wear resistant friction reducing coating is：Cr：70-75%, Ti：10-12%, Al：4-9%, N：8-10%, Fe：
0.5~1%.
In a specific embodiment, the temperature control of heat treatment step is before the forging：In 200-250 DEG C of shove charge, rod
Shape blank is heated to 650 DEG C within 1-2 hours, and is incubated 1-2 hours；Then, bar-shaped blank is heated within 1-2 hours
To 850 DEG C, and it is incubated 1-2 hours；Then, bar-shaped blank is heated to 900-1200 DEG C within 1-2 hours, and it is small to be incubated 1-2
When.
The material fabrication process of cold-working mould provided by the invention, it is resistance to by coating one layer on the surface of bar-shaped base material
Friction coat is ground, so as to effectively improve the anti-wear performance of cold-working mould, extends the cold-working mold use life-span.
Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, with reference to embodiment
The present invention is further detailed explanation.
A kind of material fabrication process of cold-working mould provided by the invention is further elaborated below,
In the specific embodiment of the present invention, it in turn includes the following steps：
1st, blanking：Prepare bar-shaped base material, the material of the bar-shaped base material is SDC99 high strength and toughness cold working mould steel.Wherein,
The mass component percentage of the SDC99 high strength and toughness cold workings mould steel is：C：0.9%, Si：1.03%, Mn：0.2%, Cr：
10.2%, Mo：1.9%, V：0.92%, Ni：0.12%, surplus Fe；
2nd, high-abrasive material coats：One layer of wear resistant friction reducing coating is coated on the surface of bar-shaped base material to obtain bar-shaped blank, institute
It is Cr base wear resistant friction reducing coatings CrTiAlN to state wear resistant friction reducing coating.Wherein, the mass component percentage of the wear resistant friction reducing coating
Than for：Cr：70-75%, Ti：10-12%, Al：4-9%, N：8-10%, Fe：0.5~1%.
CrTiAlN wear resistant friction reducings coating can effectively lift the surface abrasion resistance of SDC99 mould products.
3rd, it is heat-treated：Bar-shaped blank is heated using heating furnace.The heat treatment is divided into three phases, tool
The temperature control of body is：In 200-250 DEG C of shove charge, bar-shaped blank is heated to 650 DEG C within 1-2 hours, and it is small to be incubated 1-2
When；Then, bar-shaped blank is heated to 850 DEG C within 1-2 hours, and is incubated 1-2 hours；Then, bar-shaped blank is small in 1-2
When it is interior be heated to 900-1200 DEG C, and be incubated 1-2 hours.
It is heat-treated stage by stage, can effectively reduces the internal stress of bar-shaped blank, is ready for follow-up warm and hot forging.
The description with certain particularity detailed enough has been carried out to the present invention above.Common skill in art
Art personnel are it should be understood that what the description in embodiment was merely exemplary, without departing from true spirit and scope of the present invention
Under the premise of make it is all change should all belong to protection scope of the present invention.Scope of the present invention is by described
Claims be defined, rather than limited by foregoing description in embodiment.
