Abstract
The invention belongs to the heat-treatment industry, relates to a device capable of enabling a medium in a quenching tank to reasonably flow and particularly relates to a stirring device of a quenching tank. The stirring device comprises a transmission device fixed at the edge at the upper part of a tank body, wherein a power source for the transmission device is provided by a motor; the output end of the transmission device is fixedly connected with a stirring shaft by a flange coupler; the lower end of the stirring shaft extends into a flow guiding drum; a stirrer is fixedly connected with the lower end part of the stirring shaft; the flow guiding drum is close to the inner wall of the tank body, and the bottom of the flow guiding drum is fixed at the bottom of the tank body. The stirring device has the advantages that the temperature difference of all areas of the quenching medium in the quenching tank is relatively small, so that the loss, such as quenching distortion, cracking and scrapping of workpieces, caused by non-uniform quenching and cooling is reduced.
Description
Technical field
The invention belongs to heat treatment industry, relate to a kind of device that makes medium Rational flow in quenching tank, specifically a kind of quenching tank whipping appts.
Background technology
Quenching is integral link important in heat treatment step.Part is when cooling, and each space temperature variation is less in groove how to make the heat-eliminating medium (being quenchant) that adopts in quenching tank here, thereby reduces distorsion during quenching that workpiece causes because quench cooled is inhomogeneous, the loss such as ftracture, scrap.
How to make the medium flowing in liquid extract groove evenly reasonable, be the problem that thermal treatment worker payes attention to always.In order to guarantee that part obtains after thermal treatment, mend desired hardness and good mechanical property, and can reduce distortion and avoid cracking etc., all taked in this respect many measures both at home and abroad.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of quenching tank whipping appts is provided, adopt this whipping appts can make quenchant each space temperature variation in groove in quenching tank less, thereby reduce distorsion during quenching that workpiece causes because quench cooled is inhomogeneous, the loss such as ftracture, scrap.
According to technical scheme of the present invention: a kind of quenching tank whipping appts, it is characterized in that: comprise the transmission mechanism that is fixed on cell body top edges, described transmission mechanism provides power resources by motor, the output terminal of transmission mechanism is fixedly connected with stir shaft by flange coupling, described stir shaft bottom is stretched in guide shell, and being fixedly connected with agitator in stir shaft bottom, described guide shell arranges near cell body inwall, and cell body bottom is fixed in guide shell bottom.
As a further improvement on the present invention, described transmission mechanism comprises motion-work wheel, belt, driven wheel and transmission shaft, described motion-work wheel is fixed on motor output shaft, driven wheel is fixed on transmission shaft upper end, belt tension is on described motion-work wheel, driven wheel, and transmission shaft lower end is fixedly connected with stir shaft by flange coupling.
As a further improvement on the present invention, described guide shell comprises a large lower young tapered portion suitable for reading, semicircle transition part and connects the straight sections of described tapered portion and semicircle transition part, and described stir shaft bottom is placed in guide shell the junction corresponding to tapered portion and straight sections.
As a further improvement on the present invention, described agitator is axial flow propeller agitator.
Technique effect of the present invention is: (1) transmission mechanism is positioned at cell body top edges, compares with traditional mixing pump, does not have sealing leakage problem, and belt driver making, easy to maintenance.(2) agitator is positioned at guide shell, and guide shell stretches to bottom land always, during stirring, plays quenchant is circulated up and down in the inside and outside formation of guide shell, obtains high-speed eddy and increased circular flow also can control the effect of flow pattern.During quenching, make in quenching tank quenchant each space temperature variation in groove less, thereby reduce distorsion during quenching that workpiece causes because quench cooled is inhomogeneous, the loss such as ftracture, scrap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
