Abstract
High-ductility and wear-resistant cold-working die steel is prepared from the following raw materials in parts by weight: 0.5 to 1.0 percent of carbon, 1.2 to 3.6 percent of vanadium, 0 to 1.5 percent of silicon, 0.05 to 0.2 percent of titanium, 0.15 to 0.55 percent of manganese, 0.5 to 2.0 percent of chromium, 0.25 to 1.2 percent of molybdenum, 0.05 to 0.2 percent of nickel, 0.01 to 0.05 percent of cerium, 0.01 to 0.03 percent of strontium, not more than 0.03 percent of phosphorus, not more than 0.025 percent of sulfur and the balance iron and a few impurities. The die steel provided by the invention has a reasonable formula; the prepared die steel is high in ductility and wear-resistant; damage to a die in a using process is reduced; meanwhile, part of rare earth elements is added into the die steel, so that ductility and fatigue resistance of the die steel are further increased, and the service life of the die is effectively prolonged.
Description
Technical field
The present invention relates to a kind of die steel, be specifically related to a kind of high-toughness wear-resistant cold-work die steel.
Background technology
Die steel is used to the steel grade manufacturing the moulds such as cold-punching mould, hot-forging die, transfer mold.Mould is the main machining tool of finished parts in the industrial sectors such as machinofacture, radio meter, motor, electrical equipment.The quality of mould directly affects the quality of pressure processing craft, the precision output of product and production cost, and the quality of mould and work-ing life are except by except rational structure design and working accuracy, main by moulding stock with heat treatedly to affect.
Along with the development of Mechanical Processing Industry, rely on cold-working to be molded the part made and get more and more in production, the cold deformation mould kind of use gets more and more.Cold volume die forging (cold-heading, cold extrusion, impression etc.); Sheet-metal press working (as stretching, blanking, trimming, punching etc.); Material rolling (cold rolling, roll wheel shaping etc.).Although cold deformation mould is of a great variety, working conditions differs, and performance requriements is also different, and element task situation is close: namely all under cold state, make flow of metal, bears larger shearing force, pressure, bending force, surging force and frictional force during work.Therefore, the normal abandonment reason of cold-work die is generally wearing and tearing.Also have because of fracture, collapse power and be out of shape overproof and premature failure.
Cold-punching mould mould therefor conventional is at present high, and intensity is low, poor toughness, and wear resistance is not high yet, uses for a long time, and mould easily occurs damaging thus affects the quality of workpiece, and even scrapping appears in mould.Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide a kind of high-toughness wear-resistant cold-work die steel.
The present invention is achieved through the following technical solutions:
A kind of high-toughness wear-resistant cold-work die steel, comprises the raw material composition of following parts by weight:
Surplus is iron and a small amount of impurity.
Further, the niobium of 0.05% ~ 0.15% is also comprised.
Further, the lanthanum of 0 ~ 0.05% is also comprised.
The invention has the beneficial effects as follows: die steel proposed by the invention, formula rationally, prepared die steel, has toughness high, wear-resisting, reduce the damage in mould use procedure, meanwhile, the inside adds part rare earth element, further increasing the toughness of die steel, and fatigue resistance, thus effectively improve the mold use life-span.
Embodiment
Below in conjunction with embodiment, the present invention is described further.
Embodiment 1
A kind of high-toughness wear-resistant cold-work die steel, comprises the raw material composition of following parts by weight:
Surplus is iron and a small amount of impurity.
Embodiment 2
A kind of high-toughness wear-resistant cold-work die steel, comprises the raw material composition of following parts by weight:
Surplus is iron and a small amount of impurity.
Embodiment 3
A kind of high-toughness wear-resistant cold-work die steel, comprises the raw material composition of following parts by weight:
Surplus is iron and a small amount of impurity.
Die steel proposed by the invention, formula rationally, prepared die steel, has toughness high, wear-resisting, reduce the damage in mould use procedure, meanwhile, the inside adds part rare earth element, further increasing the toughness of die steel, and fatigue resistance, thus effectively improve the mold use life-span.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
