Description
Technical field
The utility model relates to technical field of metal heat treatment, is specially one heat treatment water-based quenching medium quenched line quenching tank.
Background technology
Current PAG water-based quenching medium is nontoxic due to it, smokelessly, do not burn, anti-aging, the physical characteristic of life-span length, and its cooling velocity is between water and oil, advantage that cooling capacity can be adjusted with the change of concentration within the specific limits, it is widely used in heat treatment industry.
PAG quenching medium be with PAG polymer based on, add that other additives are made；During workpiece quenching, the liquid temperature around workpiece is once raised to more than the inverse molten point of solution, and PAG polymer just precipitation from solution out, is suspended in quenching liquid with tiny liquid pearl form.
The PAG liquid pearl one suspending touches red heat workpiece, owing to its extraordinary wetability can adhere on surface of the work, becomes the coating of rich water that workpiece is wrapped up.PAG hardening media is exactly the cooling velocity regulating water by this coating, reduces the cooling rate of hardening media, it is to avoid workpiece generation hardening break.After workpiece cools down, the polymer that is attached on workpiece again can back dissolving in quenching liquid.Because PAG water-based quenching medium in use needs strictly to control the concentration of PAG, in order to avoid impact uses quality, so the quenching tank of use PAG water-based quenching medium is provided with the rational circulatory system.
At present, in the Equipment for Heating Processing with quenching tank for the routine, the mixing pump of quenching tank is all disposed within quenching tank centre, quenching tank surrounding does not has other agitation cycle device, and the mixing pump role of centre simply promotes the circulation of quenching tank center hardening media, unfavorable to the hardening media flowing around quenching workpiece, the entirety circulation making quenching tank is abundant not, four corners of convention square quenching tank are because of circulation system design existing defects, quenching tank surrounding is caused to become circulation dead angle, this quenching tank is relatively specific for using quenching oil, the producer of water quenching, and it is not often suitable for using hardening media, manufacturer such as PAG water-based quenching medium, and the injection pipe used in conventional quenching groove is often just for quenching workpiece, anything is not had to act on tank liquor circulation；And PAG water-based quenching medium in use needs to stir completely, make not exist around quenching tank dead angle as far as possible, make the PAG water-based quenching medium circulation in quenching tank fully, the medium in quenching tank is made fully to circulate, composition is uniform, makes workpiece quenching film forming thin and thick consistent, does not affect batch workpiece and produces, prevent from causing dielectric deposition because quenching tank exists dead angle, going bad, affect using effect and service life.
Medium above conveyer belt and near blanking port is only circulated by the effect of the carried stirring motor of traditional quenching tank, and the stirring intensity of this mixing pump can not reach too big, because eddy current produced by this pump is directly to wash away workpiece, too big easily cause workpiece quenching cracking.
Content of the invention
The utility model aims to solve the problem that PAG water-based quenching medium in use, improper due to circulation stirring and the working solution that causes rotten and the problem of part cracking, the special one that proposes is heat-treated water-based quenching medium quenched line quenching tank, replaces the mixing pump in the middle of quenching tank to solve the problems referred to above by increasing agitation cycle device in quenching tank two sides.
It for this technical solution of the utility model is, a kind of heat treatment water-based quenching medium quenched line quenching tank, including quenching tank, in quenching tank, the blanking port by being connected with quenching heating furnace is provided with blanking guipure, blanking guipure is immersed in quenching tank, is additionally provided with lifting guipure in the quenching tank under blanking guipure, it is characterised in that: it is connected with circulating pump from bottom described quenching tank by pipeline, circulating pump is connected with hydro-peening pipeline by pipeline, makes hydro-peening pipeline in the exit promoting guipure；The lifting guipure being immersed in quenching tank is also arranged above spray piping, and spray piping is connected to circulating pump；Quenching tank is also arranged above agitation cycle device, and agitation cycle device is fixed on above quenching tank by framework.
Further being improved by: agitation cycle device is multiple settings, and making the stirring vane of agitation cycle device be respectively facing the two ends of quenching tank, wherein agitation cycle device motor is variable-frequency motor.
Beneficial effect:
The utility model replaces the original only setting in the middle of quenching tank by increasing agitation cycle device above quenching tank, change the overall flow state of quenching tank liquor, promote the circulation of PAG hardening media, prevent from causing tank liquor uneven owing to circulation is insufficient, affect using effect, PAG adhesion at dead angle in quenching tank, deposition cause composition inequality, perishable raw bacterium after long-term accumulation, cause the problem that working solution goes bad and part ftractures.
By the use of this quenching tank, can effectively prevent PAG water-based quenching medium in use due to the uneven rotten smelly problem causing of stirring, change the circulatory condition of quenching tank, it is advantageously implemented the steady production of heat-treatment production line, the change in concentration making PAG water-based quenching medium is stable, do not have catastrophe, be conducive to producing control.
Use of the present utility model strengthens the circulation dynamics of quenching tank, promotes the circulation of PAG water-based quenching medium, it is therefore prevented that hardening media is not enough because of circulation dynamics, at dead angle, bath flow slowly locate deposition, causing tank liquor composition uneven, cooling rate becomes the quenching part cracking causing greatly, and the raw bacterium of fermentation.
The utility model can be to the recurrent state of tank liquor, its intensity control effectively, the agitation cycle device motor installed is variable-frequency motor, frequency can be changed according to demand, change the flow strength of tank liquor, the use of PAG water-based quenching medium and concentration of medium, temperature and stirring intensity is used to have relation, the cooling capacity of PAG water-based quenching medium can be regulated and controled by changing stirring intensity, thus the cooling capacity of medium can be changed by stirring motor, make same hardening media be applicable to more quenching workpiece.
By the redesign to quenching tank, water-based quenching medium stirring in quenching tank can be made fully, to reduce tearing tendency during workpiece quenching, extend the service life of medium, the prevention water-based quenching medium raw bacterium of fermentation, the aqueous medium causing goes bad raw bacterium, the problem that whole pond tank liquor is scrapped occurs.
