Abstract
The invention relates to a technique method for sand casting vibration pouring. The technique method comprises a high-frequency vibration technique and a high-frequency self-adaption vibration technique. After the technique method is used, the metallographic structure of a produced casting is in a dot shape and a granule shape, organization is even and fine, the organization compactness of sand casting products is better achieved, the abrasion resistance of the casting is improved, the reject ratio of the casting is reduced, enterprise cost is lowered, and economic benefits are improved.
Description
technical field
The present invention relates to casting field, be specifically related to a kind of process of sand casting vibrating casting.
Background technology
In modern mechanical manufacturing field, casting industry plays more and more important effect.In the sand casting of usual employing, often there is not wear-resisting defect in its foundry goods cast out, this just makes in engineer applied, must eliminate underproof foundry goods in a large number every year, this adds increased entreprise cost, be unfavorable for economic benefit.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of process of sand casting vibrating casting, the method can promote dense structure's property of sand casting product, improves the wearability of foundry goods, and then reduces the disqualification rate of foundry goods, reduce entreprise cost, increase economic efficiency.
For solving the problems of the technologies described above, the process of a kind of sand casting vibrating casting provided by the invention, this process comprises dither and high-frequency adaptation vibratory process.
Described dither and high-frequency adaptation vibration, its vibrating casting frequency is 110HZ-180HZ, is beneficial to refinement casting crystalline grain.
In described dither and high-frequency adaptation vibration, time of vibration starting point and time of vibration node are determined according to the size of casting crystalline grain.
After adopting such process, the metallographic structure of the foundry goods produced is point-like, little granular, and even tissue is fine and closely woven, be beneficial to the dense structure's property promoting sand casting product, improve the wearability of foundry goods, and then reduce the disqualification rate of foundry goods, reduce entreprise cost, increase economic efficiency.
Detailed description of the invention
Embodiment:
A process for sand casting vibrating casting, this process comprises dither and high-frequency adaptation vibratory process.Described dither and high-frequency adaptation vibration, its vibrating casting frequency is 110HZ-180HZ, is beneficial to refinement casting crystalline grain.In described dither and high-frequency adaptation vibration, time of vibration starting point and time of vibration node are determined according to the size of casting crystalline grain.
The invention has the beneficial effects as follows: after adopting such process, the metallographic structure of the foundry goods produced is point-like, little granular, even tissue is fine and closely woven, be beneficial to the dense structure's property promoting sand casting product, improve the wearability of foundry goods, and then reduce the disqualification rate of foundry goods, reduce entreprise cost, increase economic efficiency.
Above the present invention and embodiment are described, but the present invention being not limited to above-described embodiment, in the ken that one skilled in the relevant art possesses, can also making a variety of changes when not departing from the invention aim.
