Description
Technical field
The utility model relates to metal heat treatment equipment, is specifically related to spray quenching refrigerating unit under a kind of liquid.
Background technology
Immersion liquid cooling is the type of cooling that metal works quenching heat treatment generally uses, and for medium-and-large-sized axle rod workpieces, workpiece is dipped in the hardening liquid in quenching tank and cools fast, to improve the mechanical property of workpiece by general employing hang.In above-mentioned workpiece immersion liquid quenching process, in order to improve quench cooled ability to workpiece and speed of cooling, the hardening liquid around workpiece be made as far as possible to remain on the temperature of specifying.At present, adopt the mode that electric mixer stirring hardening liquid is set in quenching tank to improve quench cooled ability and speed of cooling more.Although this mode can make most hardening liquid in quenching tank remain on the temperature of specifying, but for medium-and-large-sized workpiece, require that agitator has enough large liquid driven power, also to ensure that the temperature of the hardening liquid flowed is even at whole workpiece surface simultaneously, make the complex structure of agitator, deployment cost is higher; And owing to there is unsurmountable alternate position spike between agitator and workpiece, therefore poor in the effect of the temperature of specifying to the hardening liquid around holding workpiece, be difficult to the immersion liquid quenching technology requirement meeting big-and-middle-sized workpiece.
Summary of the invention
The purpose of this utility model is for the problems referred to above, there is provided a kind of structure simple, configuration is convenient, and use cost is low, effectively can improve cooling power, speed of cooling and cooling uniformity energy, spray quenching refrigerating unit under the liquid that the immersion liquid quenching technology meeting big-and-middle-sized workpiece requires.
The technical scheme realizing above-mentioned purpose is: spray quenching refrigerating unit under a kind of liquid, comprise the quenching liquid bath of a top-open, in described quenching liquid bath, be provided be positioned at around workpiece perpendicular put lateral jet pipe and be positioned at the jet pipe of the horizontal end below workpiece, described perpendicular putting on lateral jet pipe is distributed with towards the side nozzle of described workpiece, described jet pipe of the horizontal end is distributed with towards the end nozzle of described workpiece; One end of the hardening liquid circulation supervisor of one assembling liquid circulating pump extend in the hardening liquid in described quenching liquid bath, the other end of this hardening liquid circulation supervisor connects side spray feed pipe and end spray feed pipe, perpendicular described in the liquid outlet of described side spray feed pipe connects puts lateral jet pipe, the jet pipe of the horizontal end described in the liquid outlet of described end spray feed pipe connects.
Further, described side spray feed pipe is equipped with side spray by-pass valve control, and described end spray feed pipe is equipped with end spray by-pass valve control.
The utility model utilizes the hardening liquid in liquid circulating pump extraction quenching tank, and spray to workpiece by the nozzle at high speeds be arranged in around workpiece, nozzle is while jet quenching liquid, the hardening liquid of periphery is driven to flow together, hardening liquid around workpiece is flowed with very high speed, thus the quick rising of quench fluid temperature around restriction workpiece, in the temperature range hardening liquid around workpiece being remained on specify.
The utility model effectively can improve cooling power, speed of cooling and the cooling uniformity energy that immersion liquid is quenched, and meets the immersion liquid quenching technology requirement of big-and-middle-sized workpiece.Have structure simple, configuration is convenient, the feature that use cost is low simultaneously.
