Description
Technical field
The utility model relates to a kind of quenching apparatus, relates in particular to a kind of pre-treatment production line quenching tank.
Background technology
Quenching is that metal works is heated to austenitizing temperature and is incubated certain hour, then to cool off greater than critical cooling velocity, to obtain non-diffusion-type transition tissue, as the thermal treatment process of martensite, bainite and austenite etc.Quench cooled is the process that the workpiece after the heating is cooled off fast, and it is most important to structural transformation and acquisition desired properties.For realizing the quench cooled of metal works, reach desired tissue and performance, the while is avoided workpiece to ftracture in process of cooling again and is out of shape, and wherein the selection of quenching refrigerating device is most important.Quenching tank is a container that is filled with quenchant, and wherein quenchant can be water, oil, fused salt and various water-soluble quenching liquids etc.In order to realize the even cooling of workpiece, obtain better quenching effect, need to be equipped with temperature-control device and whipping appts in the quenching tank, be used for the temperature of control quenchant with mobile.
Existing quenching tank mainly comprises following several structure formation:
1, simple and easy quenching tank, no temperature control and whipping appts reach mixing effect by play about the driving drive workpiece during quenching, now eliminate;
2, no temperature control adopts pressurized air to stir, and pressurized air can form bubble in medium, cause the quenching soft spots, and if quenchant catch fire easily during for oil, now seldom adopt;
3, band temperature control adopts straight V shape bilobed wheel agitator to stir, and straight V shape bilobed wheel agitator is placed in around the quenching tank, upwards flows by pipeline by the quenchant in the rotation compression pipe of impeller, forms upper-turn-type and stirs.This mode is a kind of alr mode that generally adopts at present; this quenching tank also is a kind of quenching tank that generally adopts at present; advantage is temperature control to be arranged and stir; can guarantee that quenchant uses in optimum temperature range; can not cause the unusual or early failure of cooling because of temperature anomaly; can make part when quenching, obtain uniform cooling performance by stirring, and the rate adjusted of agitator.But also there are some shortcomings in this quenching tank:
(1) because straight V shape agitator is installed in around the quenching tank, increases the volume of quenching tank, be unfavorable for the reasonable utilization in space.Quenchant is forced-flow under the pressure of paddle wheel, because pipe loss needs the mixing effect that bigger agitator just can reach to be needed, energy consumption is big, does not utilize energy-conserving and environment-protective;
(2) mixing direction can only be mode from bottom to top, can not in quenching tank, form three-dimensional stirring, therefore, the quench cooled effect is not good sometimes, when the lower floor's part volume on the platform of particularly quenching is big, can hinder flowing that medium makes progress, can not realize that the different zones temperature field is even, thereby cause the cooling of upper strata part undesirable, influence the workpiece structure property.In addition, because of arts demand, quench when needing side to stir, adopt this equipment then can't realize;
(3) the quenching platform is fixed, can not rise, descend, the placement of part when being unfavorable for quenching.

Technique scheme, described submersible agitator is fixedlyed connected with quenching cell body bottom bracket, is rotationally connected with fixed support around the quenching cell body; Described submersible agitator is detachable.
Technique scheme, the quenching platform jacking system that also comprises the quenching platform that is positioned at the quenching cell body and be positioned at the quenching tank external body, described quenching platform jacking system comprises drive system, transmission system and Controlling System, and described transmission system two ends link to each other with drive system with the quenching platform respectively.
Technique scheme, described quenching cell body upper end one side also is provided with tank level control system, described tank level control system comprises level tank, is positioned at the float-ball type liquid level meter of level tank inside and the induction post that links to each other with the float-ball type liquid level meter, also comprises the tubing system and the hardening liquid control valve that are positioned at quenching cell body one side.
Technique scheme, described tank level control system next door also is provided with temperature controlling system.
After adopting technique scheme, the utlity model has following positive effect:
(1) the utility model submersible agitator volume is little, and it is low to consume energy, energy-conserving and environment-protective, and agitator directly contacts with hardening liquid, can realize three-dimensional stirring; Can as workpiece quantity what or workpiece volume size, select to put into quantity and the position of submersible agitator according to actual needs, realize cooling uniformity; Can also regulate stirring frequency by diving stirring and adjusting device before quenching or in the quenching process according to actual needs, can guarantee favorable cooling effect, avoided the quenching tank of traditional belt stirrer all to have only a kind of alr mode in any case again, inhomogeneous cooling, the effect brought are bad, and the defective that wastes energy;
(2) be positioned at quenching cell body submersible agitator and fixed support all around and be rotationally connected, and detachable, so can regulate angle and the height of submersible agitator as required, guarantee cooling uniformity, reach best cooling performance;
(3) the utlity model has the quenching lifting table, and the quenching platform jacking system that passes through the outside is controlled rising, the decline of quenching platform, pick and place part by fork truck, the level of automation height, can enhance productivity greatly, improve workman's production environment, the injury that quench hot liquid produced the workman when minimizing workman operated in person;
(4) tank level control system can be identified the height of hardening liquid automatically, can supply with hardening liquid automatically when hardening liquid is not enough in the quenching cell body; Temperature controlling system then can be monitored quench fluid temperature at any time and change, and carries out heat exchange by the tubing system in the tank level control system and extraneous plate-type heat exchanger or cooling tower when temperature is too high and lowers the temperature, thereby guarantee the quality of quenching.
