Description
Technical field:
The present invention relates to a kind of casting of semi-molten equipment and technological process thereof.
Background technology:
Traditional metal casting is far above the liquid metal of melting point metal, be cast in sand mould or die casting in metal die; , first there is nucleus in liquid metal crystallisation by cooling, then around nucleus, occurs dendroid dendrite arm, and be attended by shrinkage.So the casting deformation that this casting method produces is more serious, and there will be crack.Recent two decades, western developed country works out casting of semi-molten technology; Namely in liquid metal crystallisation by cooling process, around stirring nucleus, occur that dendroid dendrite arm interrupts, form the semi-solid-state metal that microcrystal grain metal and liquid metal mix, microcrystal grain metal accounts for 50%～80%.Then these semi-solid-state metal die casting in metal die.The method that stirs liquid metal has: ultrasonic wave paddling process, rotary magnetic field stirring method and piston pump mechanical mixing method.But these stirring means liquid towards metal crystallisation by cooling are controlled, and that is to say and cannot control refrigerating capacity.
Summary of the invention:
Casting of semi-molten equipment of the present invention, its structure is as follows: metal flows in holding furnace after calciner fusing, then flow to by electronic casting valve stir in cooling bath, the machine that is stirred stir cooling, finally by die casting machine press-in die.Before stirring cooling bath, height is rear low, stirs in cooling bath and has three mixers to stir cooling liquid state metal.Stir in cooling bath several thermocouple temperature sensors are housed.In casting of semi-molten equipment, oscillating disk viscometer is housed, the flat board of oscillating disk viscometer is contained in and stirs in cooling bath.Stir cooling bath top several infrared temperature sensors are housed.Mixer is made up of the refractory ceramics sheath with stupefied, metal sleeve, hollow rotating shaft, driven gear, toothed gearing electric motor, output gear, water pipe, motorized adjustment water valve, track, dolly, reciprocating mechanism.The outer surface cover of metal sleeve has ceramic sheath.Hollow rotating shaft lower end is fixed on metal sleeve bottom, and the top of hollow rotating shaft is through metal sleeve top center hole.Many exhaust holes are arranged at metal sleeve top.On that in metal sleeve section hollow rotating shaft, there are many apertures.That outside metal sleeve section hollow rotating shaft is fixed on dolly by bearing.On hollow rotating shaft above bearing, driven gear is housed, the output gear of toothed gearing electric motor engages with driven gear, and toothed gearing electric motor is contained on dolly.Distilled water enters the shell of toothed gearing electric motor, cooling toothed gearing electric motor by pipeline, then enters water pipe by motorized adjustment water valve.Water pipe is fixed on dolly, and the lower end of water pipe is connected with hollow rotating shaft movable upper end by organic silicon rubber sealing ring.Article three, track is across stirring above cooling bath, and reciprocating mechanism moves reciprocatingly dolly on cross track.Reciprocating mechanism can be slide block movement reciprocating mechanism, and it drives dolly to do slide block movement by motor by escapement and crank.Reciprocating mechanism can be air rammer or hydraulic piston reciprocating mechanism, and hydraulic piston reciprocating mechanism is made up of hydraulic pump, hydraulic oil container, solenoid directional control valve, hydraulic cylinder, piston, pull bar, back-moving spring.
The technological process of casting of semi-molten of the present invention is as follows: 1) metal is put into calciner heat fused and become liquid metal.2) liquid metal melting in calciner is progressively flowed in holding furnace.3) regulate the control of electronic casting valve to flow into the flow that stirs liquid metal in cooling bath from holding furnace.4) by the temperature of liquid metal in several contact type temperature sensors and each section of stirring cooling bath of several infrared temperature sensor measurement.5) give mixer and reciprocating mechanism energising, the output gear of toothed gearing electric motor drives hollow rotating shaft to rotate by driven gear, thereby drives the refractory ceramics sheath with stupefied of metal sleeve and outside to rotate in mobile liquid metal.The motor of slide block reciprocating mechanism drives escapement to rotate, drive dolly to move reciprocatingly in orbit by crank, make to rotate limit laterally moving reciprocatingly at stirring cooling bath with stupefied refractory ceramics sheath in the liquid metal the inside of stirring in cooling bath thereby drive the mixer being equipped with on dolly to move reciprocatingly.Or the hydraulic pump of hydraulic reciprocating movement mechanism energising, hydraulic pump extracts hydraulic oil from hydraulic oil container, the normally closed outlet of solenoid directional control valve of then opening by energising enters hydraulic cylinder, making piston promote dolly by pull bar moves forward in orbit, thereby the mixer being equipped with on drive dolly moves forward and makes to move forward on the rotation limit, liquid metal the inside of stirring in cooling bath with stupefied refractory ceramics sheath, in stirring cooling bath, laterally move, and compression reseting spring.When dolly knocks after limit switch in front, stop the electricity of solenoid directional control valve, the back-moving spring of compression releases energy and promotes piston the hydraulic oil in hydraulic cylinder mouthful is expressed in hydraulic oil container by often outputing of solenoid directional control valve, the pull bar connecting together with piston pulls dolly to move backward in orbit, thereby the mixer being equipped with on drive dolly backward mobile making rotates limit backward with stupefied refractory ceramics sheath in the liquid metal the inside of stirring in cooling bath, at the transverse shifting that stirs cooling bath, until dolly mobile bumping against after the limit switch of back backward, solenoid directional control valve is switched on again, respectively with three mixers three hydraulic piston reciprocating mechanisms connecting together of dolly solenoid directional control valve wheel flow-thru electrode and lose and moving three dollies moved reciprocatingly.The mixer of temperature descending section regulates the water yield of the distilled water that enters water pipe by motorized adjustment water valve according to the signal of the contact type temperature sensor of this section and infrared ray sensor test, distilled water is vaporized and is entered in metal sleeve to heat up and absorbs a large amount of heats in hollow rotating shaft, has reduced the temperature of ceramic sheath, cooling liquid metal reduces the temperature of liquid metal.The mixer of crystallized region regulates the water yield of the distilled water that enters water pipe by motorized adjustment water valve according to the signal of the test of this section of oscillating disk viscometer, distilled water is vaporized and is entered in metal sleeve to heat up and absorbs a large amount of heats in hollow rotating shaft, has reduced the temperature of ceramic sheath, cooling liquid metal makes more liquid metal solidification.According to the functional relation of the degree of crystallinity of the viscosity of liquid metal and liquid metal, the large degree of crystallinity of viscosity is just high, and the shared rate control the metallic crystal particulate solidifying in semi-solid-state metal is between 80 50 percent to percent.6) finally use die casting machine in semi-solid-state metal press-in die.
Casting of semi-molten belongs to metal hot investment casting, and casting foundry goods out only need process, even not need processing just can become product a little.The foundry goods physical characteristic that casting of semi-molten is produced is good especially, not easy fracture, and not yielding, mechanical strength is high, can be used for producing aluminium alloy wheel hub.
