Abstract
The invention relates to a cold rolling die, which comprises the following the components by weight parts: 0.5-0.9 parts of bismuth, 0.3-0.5 parts of palladium, 0.05-0.08 parts of ruthenium, 0.06-0.12 parts of molybdenum, 0.23-0.58 parts of potassium, 0.35-0.68 parts of lithium, 0.12-0.35 parts of sodium and 80-95 parts of iron. The cold rolling die has the advantages that the composition proportion is scientific and reasonable, crack phenomenon can not be generated after long-term usage, wear rate is low, and usage life is greatly prolonged.
Description
Technical field
The present invention relates to a kind of mould for cold milling.
Background technology
Operationally, because the resistance to deformation of machined material is larger, the working portion of mould bears the large pressure of very large cold-work die steel, bending force, surging force and frictional force to cold-work die steel.Cold-work die wear rate is high.Also have because of fracture, collapse power and be out of shape overproof and premature failure.Greatly reduce work-ing life, the demand of enterprise can not be met.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of mould for cold milling.
The technical solution used in the present invention is:
A kind of mould for cold milling, comprises the composition of following weight part:
Bismuth 0.5-0.9 part;
Palladium 0.3-0.5 part;
Ruthenium 0.05-0.08 part;
Molybdenum 0.06-0.12 part;
Potassium 0.23-0.58 part;
Lithium 0.35-0.68 part;
Sodium 0.12-0.35 part;
Iron 80-95 part.
Preferably, the calcium of 0.36-0.58 weight part can also be added.
Preferably, the manganese of 0.23-0.35 weight part can also be added.
Preferably, the copper of 0.011-0.1 weight part can also be added.
Advantage of the present invention is: the component of this kind of mould is scientific and reasonable, and be in use not easy the phenomenon occurring fracture, wear rate is low, substantially prolongs work-ing life.
