Description
Technical field
What the present invention relates to is a kind of immersion liquid and the controlled chilling equipment that sprays the combined quench of quenching, and particularly a kind of medium that adopts injects and discharge method immersion liquid and the controlled chilling equipment that sprays the combined quench of quenching fast.Belong to metallic substance thermal treatment field.
Background technology
Quenching is meant steel part is heated to A
C3Or A
C1The above a certain temperature of point keeps certain hour, obtains the thermal treatment process of intended tissue then with suitable speed cooling.For tissue and the performance that obtains to be scheduled to, cooling apparatus many routines, special and combination is used.Wherein adopting the compound method of cooling that the immerseable shrend is quenched with spray, gas is quenched (air cooling) combines is exactly one of them.This equipment normally is made up of quenching tank, immersion liquid quenching lifting table, spray quenching system etc., working process is at first to be that the workpiece that will intend quenching is placed on the immersion liquid quenching lifting table, lifting table decline makes among the workpiece dip quench medium then, treat the workpiece surface structural transformation become martensite after immersion liquid quenching lifting table rise to more than the medium liquid level, slowly cool off (spray is quenched, gas is quenched (air cooling)), to make the martensitic transformation on top layer after being raised to certain temperature be that toughness immerses workpiece in the water behind the tempered martensite preferably again when the temperature on top layer is counter.This kind equipment is finished the fast cold and slow cooling conversion of quenching process by immersion liquid quenching lifting table.Find by literature search, Chinese patent application number: 02137614.X, name is called: periodical stepped quenching cooling equipment, this patent disclosure a kind of periodical stepped quenching cooling equipment, comprise: cell body, the direct fluid tube, propeller stirrer, the lifting gantry drive system, cover plate, lifting gantry, nozzle (one), nozzle (two), its mode of connection is: the side at cell body is provided with propeller stirrer, the water screw of propeller stirrer stretches into below the liquid level, the direct fluid tube is the U type, the water screw of propeller stirrer inserts an opening of direct fluid tube, its another opening is located at the below after the quenching part immerses liquid, the lifting gantry drive system is located at the top of cell body one side, and be connected with cover plate with lifting gantry, cell body is provided with cover plate, below cover plate, be provided with nozzle (), be provided with nozzle (two) above the liquid level in cell body.But for the quenching of large size and large heavy workpiece, the lifting table that is used for year workpiece immersion liquid causes the manufacturing of equipment and maintenance cost higher owing to the weight of quenching part is excessive, and it is bigger that the difficulty of spraying the nozzle of quenching is set on the load-carrying lifting table simultaneously.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of quick quenching refrigerating device of quenching and making up with discharge method immersion liquid and spray that injects of medium that adopts is proposed, make it omit lifting gantry, avoided adopting complex structure and manufacturing, the higher lifting table of maintenance cost, the reliability of equipment has obtained significantly improving.
The present invention is achieved by the following technical solutions, the present invention includes: the quenching cell body, the quick injected system of medium, the blower fan cooling system, upper cover plate, last cooling jet, medium stirs and current-equalizing system, following cooling jet, material carrier platform, the quick return-flow system of medium, its mode of connection is: the quick injected system of outer setting medium of quenching cell body top one side, the quick return-flow system of outer setting medium at the opposite side on top, the inner one or both sides of quenching cell body are provided with medium and stir and current-equalizing system, quenching tank external body one or both sides are provided with the blower fan cooling system, the top of quenching cell body is provided with the upper cover plate of energy move left and right, the downward last cooling jet of nozzle is set on the upper cover plate, material carrier platform is fixed on the middle part of last liquid level Yu the following liquid level of quenching tank, and the following cooling jet that spout makes progress is set in the bottom of material carrier platform.The quick injected system of quenching cell body and medium, the quick return-flow system of medium and blower fan cooling system all are UNICOMs.
The quick injected system of medium is made up of pump valve, is arranged on the one or both sides of quenching cell body.The quick return-flow system of medium is made up of valve, is arranged on the one or both sides of quenching cell body.
Material carrier platform is fixed between intravital upward liquid level of quenching tank and the following liquid level, the quenching part is embedded in certain depth in the medium just when the medium in the quenching tank is in liquid level, make the medium in the whole quenching tank under the effect of agitator, participate in heat exchange, material carrier platform and play cooling jet all are among the atmosphere when the medium in the quenching tank is in down liquid level, and the quenching part that is placed on this moment on the material carrier platform can be realized spray quenching or quenching under the blower fan cooling.
Last cooling jet is distributed in the plane domain of quenching service area with following cooling jet.The ejection medium of nozzle can be and identical liquid, gas and the gas liquid mixture of medium in the cell body.
The present invention will have the immersion liquid quenching tank of the immersion function of quenching and spray cold (nozzle) combined, during use, the quenching part at first heats and carries out precooling on the material carrier platform of transferring to quenching tank then, precooling finishes the back and opens the quick injected system of medium, the medium of Zhu Ruing reaches the last liquid level of quenching tank at short notice, medium before the injected media in the immersion liquid quenching tank is in the following liquid level of workpiece quenching service area, the following medium of following liquid level accounts for needs more than 5 times of injected media amount, needs injected media amount shortening shared time of injected media and the medium that q.s is provided to participate in the purpose of heat exchange to reach minimizing.Opening the agitator that stirs with current-equalizing system simultaneously also participates in the medium of bottom simultaneously, opening the quick return-flow system of medium after immersion liquid is quenched and finished falls the medium quick drain of injecting, open to go up subsequently cooling jet spray cold with play cooling jet or open blower fan carry out air-cooled, the purpose of realization marquenching.Whole process can be finished under the control of computer.
Compared with prior art, the present invention adopts medium to inject fast with discharge method and realizes immersion liquid and the spray combined quench of quenching, be specially adapted to quench cooled to large size, big weight quenching part, omitted lifting gantry, no longer realize quenching with the quenching lifting table, simple in structure, reduced cost and failure rate, also make the control immersion liquid quenching of especially big quenching part become possibility simultaneously.
