Description
Technical field
The present invention relates to stamping parts technical field of material, and in particular to a kind of high-quality mechanical performance stamping parts material
Preparation method.
Background technology
Punching press is that depended on pressure machine and mould apply external force to sheet material, band, tubing and section bar etc., is allowed to produce plastic deformation
Or separation, so that the forming and machining method of the workpiece of shape and size needed for obtaining.Stamping parts material is in mechanical industry production
In extremely important status, such as in automobile manufacturing process by 60%-70% metallic element need punch process into
Type.And the mechanical performance of stamping parts material in itself, such as hardness, ductility etc. will determine whether it can expire after the completion of punching press
Sufficient product is used and technical performance.
During plate heat treatment, the martensitic phase intensity obtained after quenching is higher, can effectively promote heat to add
The hardness of work backlash laminate materia is substantially improved.However, excessive high hardness easily increases the fragility of stamping parts, in punching course
Easily there is local micro-crack, greatly reduce the yield rate and service life of stamping parts；Opposite, if obtaining softer iron
Ferritic phase, although reduce the hardness and fragility of material body, but excessively excellent ductility can cause material to be easy in punching
Plastic deformation is produced at compression mould cutting edge, and then causes stamping parts edge to produce excessive excessive overlap and burr so that punching press
Part can not meet use requirement.

For iron and inevitable impurity.
Preparation process is as follows：
1) by ordinary scrap steel melting, cupric oxide, chromium steel, molybdenum steel, nickel steel, borax is added after molten steel is melting down, 1490- is warming up to
1520 DEG C are changed into liquid molten steel, go out to add for 10 minutes before molten steel aluminum oxide, silica, calcium oxide, ferromanganese progress precipitation desoxydation,
Adjusting component makes each element composition meet the mass fraction requirement of chemical composition in above-mentioned high-quality stamping parts material, skims, cast
Shaping, pouring temperature is 1340-1390 DEG C, is cooled to room temperature, and cleaning burr obtains casting；
2) by step 1) medium casting is warming up to 900-950 DEG C of insulation makes within 30-60 minutes microstructure homogenization, then with 200-300
DEG C/min is quickly cooled to room temperature, obtain quenching casting.
3) by step 2) in quenching casting be warming up to 600 DEG C again, be incubated 10 minutes, be air-cooled to room temperature.
It is preferred that, the step 1) in ordinary scrap steel melting, molten steel it is melting down after add cupric oxide, chromium steel, molybdenum steel, nickel steel,
Borax, is warming up to 1500 DEG C and is changed into liquid molten steel, the pouring temperature is 1350 DEG C.
It is preferred that, the step 2) medium casting is warming up to 935 DEG C, is incubated 45 minutes.
It is preferred that, the step 2) in cooling velocity be 280 DEG C/min.
The invention provides a kind of preparation method of high-quality mechanical performance stamping parts material, its advantage is：The present invention
Feed components Combination preferably, when material body is warming up to 935 DEG C, mainly exists in material with austenite, due to nickel, molybdenum
Incorporation effectively increases the stability of austenite, hinders the precipitation of carbide, then with the fast quickly cooling of 280 DEG C/min cooldown rate
When but, also cause a part of carbide because cooling velocity is too fast and can not separate out in time, and then form the martensite of high rigidity
Phase；Another part carbon separates out to form the soft phase of ferrite, and chromium can be solid-solution in ferrite to play and stablize ferritic work
With.The present invention is combined using the soft phase of ferrite mutually coordinated and high hard martensitic phase, needed for both having ensure that stamping parts material
Hardness, also obtained preferable plasticity.Stamping parts material of the present invention and preparation method are easily achieved, and can be greatly improved
The yield rate of stamping parts material, has broad application prospects.
