Abstract
The invention relates to a cold rolling die. The die comprises, by weight, 0.5-0.9 parts of C, 0.3-0.5 parts of Pd, 0.05-0.08 parts of quartz sand, 0.06-0.12 parts of Mo, 0.23-0.58 parts of K, 0.35-0.68 parts of Li, 0.12-0.35 parts of Na and 80-95 parts of Fe. The die has the advantages of scientific and reasonable components, unlikely fracturing in the use process, low wear rate and substantially prolonged service life.
Description
Technical field
The present invention relates to a kind of mould for cold milling.
Background technology
Cold-work die steel is when work, and because the resistance to deformation of machined material is larger, the working portion of mould bears pressure, bending force, surging force and the frictional force that very large cold-work die steel is large.Cold-work die wear rate is high.Also have because of fracture, collapse power and be out of shape and overproofly lost efficacy in advance.Greatly reduce work-ing life, can not meet the demand of enterprise.
Therefore,, for addressing the above 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 mould for cold milling, comprises the composition of following weight part:
Carbon 0.5-0.9 part;
Palladium 0.3-0.5 part;
Quartz sand 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, can also add the calcium of 0.36-0.58 weight part.
Preferably, can also add the manganese of 0.23-0.35 weight part.
Preferably, can also add the copper of 0.011-0.1 weight part.
Advantage of the present invention is: the component of this kind of mould is scientific and reasonable, is in use not easy to occur the phenomenon of fracture, and wear rate is low, has greatly extended work-ing life.
