Abstract
The invention discloses a method for pouring a gear. According to the method, the gear can be poured for two or more times, the temperature or ingredients of pouring liquid is or are changed to perform next pouring when the last pouring the finished, different parts of the gear are poured under different conditions, therefore, the tooth portion of the gear has certain toughness to prevent from cracks, and tooth walls do not deform or crack.
Description
Technical field
The present invention relates to gear cast field, field, the method particularly relating to the cast of a kind of gear.
Background technology
In prior art, cast product is one-shot forming, internal structure and the surface property parameter of cast product are identical, and in gear, it is desirable to the inside of teeth portion has certain toughness and prevents slight crack, the outside hard wear resistant of teeth portion, tooth wall to have certain toughness simultaneously, owing to gear wall requires have different characteristics from after teeth portion molding, and common one-shot forming, both can be made to have identical character, reduce the quality of product.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the method that it is an object of the invention to provide the cast of a kind of gear, it is intended to the problem solving the cast of prior art middle gear.
Technical scheme is as follows:
The method of a kind of gear cast, wherein, described method is to carry out gear twice or the cast of above number of times, after once-cast completes, pours into a mould after changing the temperature of potting syrup or the composition of potting syrup next time.
The method of a kind of gear cast, wherein, is spaced 1 minute, the temperature of adjustable potting syrup or composition between adjacent twice cast.
The method of a kind of gear cast, wherein, separately pours into a mould teeth portion and the tooth wall of gear, pours into a mould the most under different conditions.
The method of a kind of gear cast, wherein, tooth wall part is added copper water in casting process and is poured into a mould, and increases the toughness of tooth wall part.
The method of a kind of gear cast, wherein, teeth portion part uses different temperature quenchings from tooth wall part, so that teeth portion is different with the toughness of tooth wall.
The method of a kind of gear cast, wherein, teeth portion part uses frozen water to carry out very fast cooling.
Beneficial effect: the present invention is by repeatedly pouring into a mould gear, i.e. after once-cast, postpone certain time, adjust temperature and the composition of potting syrup, repeatedly moulding by casting, and when cast, take the separately cast of teeth portion and tooth wall, tooth wall is carried out the mixing cast of copper water, so that tooth wall has certain toughness and quenches tooth wall and teeth portion at different temperatures, ensure that the performance of tooth wall and teeth portion, make tooth wall have toughness and be not likely to produce slight crack, teeth portion hard wear resistant.
Detailed description of the invention
The present invention provides a kind of method that gear is poured into a mould, and for making the purpose of the present invention, technical scheme and effect clearer, clear and definite, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
A kind of method of gear cast, wherein, described method is to carry out gear twice or the cast of above number of times, after once-cast completes, pour into a mould after changing the temperature of potting syrup or the composition of potting syrup next time, gear wall from require after teeth portion molding that the character having is different, therefore gear wall and teeth portion are separately poured into a mould, due to common molten iron casting, after last molding, lacking toughness, and gear wall needs have toughness, the present invention is preferably after once-cast completes, and the composition of change potting syrup has different character after making gear wall and teeth portion molding.
Further, the method of described gear cast, wherein, it is spaced five minutes between adjacent twice cast, the temperature of adjustable potting syrup or composition, the composition of the temperature and potting syrup that adjust potting syrup can change the character after molding, to reach the requirement of user, the interval time of adjacent twice cast is controlled by the temperature of molten iron, the component of cast is preferably provided with system for detecting temperature, when molten iron temperature drops to below 1200 degree, can pour into a mould the most next time, for smaller component, adjacent cast the most not can exceed that 1 minute interval time, because component is little, cooling is fast.For bulky component, owing to heat radiation is slow, cast interval time can be longer, typically can have the time of 2 ~ 3 minutes, and disclosed by the invention is gear cast, is consequently belonging to primary structural component category, the preferably duration of pouring and is spaced apart 1 minute.
Further, the method for described gear cast, wherein, teeth portion and the tooth wall of gear are separately poured into a mould, pours into a mould the most under different conditions.
Further, the method of described gear cast, wherein, tooth wall part is added copper water in casting process and is poured into a mould, increase the toughness of tooth wall part, copper, as metal relatively common in daily, has stronger ductility, mixes with molten iron after melted for copper, obtain mixing potting syrup, there is after can making tooth wall part molding certain ductility, thus be not easy to produce slight crack, improve the quality of product.
Further, the method of described gear cast, wherein, teeth portion part uses different temperature quenchings from tooth wall part, so that teeth portion is different with the toughness of tooth wall, different temperature quenchings, the character of the product obtained is different, after utilizing frozen water cooling rapidly can make molding, product has the strongest hardness, and teeth portion requires have different character from after tooth wall part molding, teeth portion part needs have the highest intensity, and tooth wall part then requires have certain toughness, and therefore the present invention uses different temperature that teeth portion and tooth wall are carried out Quenching Treatment.
Further, the method for described gear cast, wherein, teeth portion part uses frozen water to carry out very fast cooling, with frozen water, teeth portion is cooled down rapidly, for general cooling means, containing impurity in air, the natural cooling meeting waiting time is oversize, have more impurity simultaneously, use frozen water to cool down rapidly, teeth portion can be made to have higher hardness, slight crack will not be produced, it is ensured that the quality of product.
In sum, the present invention is by repeatedly pouring into a mould gear, i.e. after once-cast, postpone certain time, the temperature of adjustment potting syrup and composition, repeatedly moulding by casting, and when cast, take the separately cast of teeth portion and tooth wall, tooth wall is carried out the mixing cast of copper water, so that tooth wall has certain toughness and quenches tooth wall and teeth portion at different temperatures, it is ensured that tooth wall and the performance of teeth portion, make tooth wall have toughness and be not likely to produce slight crack, teeth portion hard wear resistant.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, all these modifications and variations all should belong to the protection domain of claims of the present invention.
