Description
Technical field
The present invention relates to a kind of environmental protection and energy saving sand casting process, belong to the machine casting technical field.
Background technology
In the modern mechanical industry, various fields such as automobile, mine, metallurgy, space flight and aviation, agricultural machinery still are all to be unable to do without casting in the daily life.Wherein, sand casting is to use at present casting technique very widely, has characteristics such as wide adaptability, cost are low, technical maturity.At present, sand casting process can be divided into: clay wet sand casting, the casting of clay dry sand mold, water-glass sand mold casting, self-setting silicate process mold casting, resin bonded sand mould casting etc.
But, mainly there is following problem in sand casting: (1) needs use mineral sand such as a large amount of quartz sand, limestone sand, zircon sand, chromite sand, when obtaining these mineral resources, can damage natural environment inevitably, casting process can produce a large amount of antiquated sands and dust simultaneously, can cause environmental pollution.(2) owing to use a lot of complicated Casting Equipments of Machine, not only consume a large amount of electric energy, also can produce the high-decibel noise, worsen production on-site environment.(3) the sand mold thermal conductivity factor is little, and radiating condition is poor, causes easily that casting crystalline grain is thick, the numerous defectives of tissue looseness, sand hole, pore or the like, makes the mechanical performance of foundry goods lower.In addition, in technical process, be easy to generate mould shift when greensand mold molding, mould assembling, because wet type intensity is lower, molten metal causes the case that rises, scab after entering casting mold easily, makes the casting dimension error bigger, rough surface simultaneously; Dry sand mold casting, water-glass sand mold casting etc. are then because the sand mold retained strength is higher, and labour intensity is big during casting cleaning, and the dust concentration height can the grievous injury health of operators.
In addition, understand according to the applicant, in the evolution of lost foam casting process, a kind of magnetic molding process technology that adopts shot or shot once occurred, yet the very strong electromagnetic field of this arts demand is shot or shot fixedly, can produce bigger electromagnetic pollution undoubtedly; Because magnetic molding process is harsh to the foundry goods shape need, thereby makes the adaptability of this technology be very limited; Simultaneously, this technology only is fit to lost foam casting process, can't directly overlap to be used for other casting technique.In addition, misrun, elephant skin, carburizing, surface carbon hole and the inner stain black line that causes owing to the existence of foam plastics mould, also happen occasionally because of casting flaws such as magnetic field intensity the control improper collapsing that causes, puncture and expansions.Simultaneously, the foam plastics mould of lost foam casting can only use once, and foamed plastics density is little, intensity is low, and apperance is yielding, influences casting dimension accuracy, and the gas that the apperance vaporization produces during casting pollutes the environment.
At present, each producer that grasps lost foam casting process often gets up the key point of lost foam casting process as commercial privacy protection, cooperate less each other.For other producers, it is too high to obtain ripe lost foam casting process cost to existing producer, and independent research and development are consuming time longer, if can make improvement to the sand casting process of using extensively, maturity is high, make it to overcome existing defective, then help promoting the market competitiveness of this producer greatly, booster action is played in producer's development.
Summary of the invention
Main purpose of the present invention is: overcome the problem that prior art exists, a kind of environmental protection and energy saving sand casting process is provided, need not to consume mineral sand, can not produce mineral sand dust in the production process, avoid environment is produced pollution.
Technical conceive of the present invention is as follows: the applicant is through repeatedly practising research, on the basis of existing sand casting, use for reference magnetic molding process technology, develop the sand casting process that adopts the metal molding sand, thereby avoid occurring adopting the problem of next mineral resources consumption in mineral abrasive band and generation harmful dust.
The present invention realizes that the technical scheme of above-mentioned main purpose is as follows:
A kind of environmental protection and energy saving sand casting process is characterized in that, may further comprise the steps:
The first step, metal sand, the 0.26-1.5 parts by weight of adhesive mixing of 100 weight portions made the metal molding sand; Described metal sand is made by the magnetic metal material; Described metal sand sieves before use, and sieve number is the 20-140 order;
Second step, elder generation install sandbox and model group, charge into the metal molding sand again to trunkful; Described sandbox, model are made by nonmagnetic substance respectively;
The 3rd step, described sandbox outside are provided with electromagnet and vibrator, and sandbox is between two magnetic poles of electromagnet; Vibrator vibration sandbox was opened at least 5 seconds by elder generation, closed vibrator then and produced electromagnetic force to the electromagnet energising, and while metal molding sand carries out cure process and makes sand mold; Treat to remove electromagnet after sclerosis finishes or make the electromagnet outage; Trip out sand mold, and, promptly make casting mold at sand mold surface-coated high-temperature resistant coating;
The 4th goes on foot, casting mold is placed between electromagnet two magnetic poles, after the electromagnet energising, injects molten metal in casting mold, treats to remove electromagnet or make the electromagnet outage after molten metal solidifies the formation foundry goods; Treat that foundry goods cools off after 15 minutes at least, carries out knockout and Shot Blasting to foundry goods.
This process using metal molding sand need not mineral sand, thereby avoids consuming excessively mineral resources; Metal molding sand mechanical strength height is difficult for fragmentation, can not produce mineral sand dust in the production process, avoids production environment is polluted; In addition, because the metal sand in the metal molding sand is from great, profile rounding, need not big external force during moulding and can form steady and audible die cavity, therefore only need simple device can organize line production, thereby save a large amount of electric power, and reduce moulding, the noise when cleaning equipment turns round, improve the production scene working environment; Simultaneously, utilize electromagnetic force to strengthen casting mold, both can reduce the binding agent consumption, be convenient to foundry goods is carried out knockout and Shot Blasting, improved mold stiffness and hardness again, casting dimension accuracy is improved.
What need stress is, the applicant is after adopting this technology, the mechanical performance of finding foundry goods unexpectedly has conspicuousness to improve, and has improved 1-2 rank as ironcasting or steel-casting mechanical performance, and the aluminum casting mechanical performance can make product with permanent mold casting and compare favourably; Simultaneously, casting dimension accuracy also has remarkable lifting, has improved 1-2 grade.The applicant thinks after after further study, may be because the metal molding sand of this process using has the thermal conductivity higher than mineral sand on the one hand, can effectively improve the thermodynamic condition in the foundry goods crystallization process, may be because the electromagnetic force of this process using is not only strengthened casting mold on the other hand, also the foundry goods crystallization process has been produced favourable influence, significantly improved the inherent quality and the dimensional accuracy of foundry goods aspect two under the combined influence at this.
