Abstract
The invention relates to the field of quenching tanks, in particular to a quenching tank for small-sized castings. The quenching tank comprises a tank body, a workbench, a servo motor and a lead screw, wherein casting loading baskets are arranged inside the tank body, each casting loading basket comprises a reticular basket body and a handle, the workbench is positioned on the tank body, the servo motor is positioned on the workbench, the lead screw is arranged at the output shaft end of the servo motor in a transmission connecting manner, and the basket bodies are fixedly arranged on the lead screw; after the adoption of the technical scheme of the quenching tank for small-sized castings, the quenching temperature can be uniformly transferred.
Description
Technical field
The present invention relates to quenching bath field, specifically a kind of small-sized foundry goods quenching bath.
Background technology
Quenching metal works is heated to a certain proper temperature and keeps for some time, immerses the metal heating processing technology of cooling fast in quenching media immediately.The object of quenching makes supercooled austenite carry out martensite or bainite transformation, obtain martensite or bainite structure, then the tempering with differing temps is coordinated, significantly to improve the rigidity of steel, hardness, wear resistance, fatigue strength and toughness etc., thus meet the different service requirementss of various mechanical component and instrument.Physics, chemical property that the ferromegnetism, solidity to corrosion etc. that also can meet some special steel material by quenching are special.
Quenching bath is quenching technology necessary equipment, is mainly used in holding quenching media.Existing quenching bath, workpiece enters Chi Tihou, quenching media is static, such workpiece surface easily forms one deck steam film, this layer of steam film can affect the transmission of temperature, easily makes workpiece under the state of Quench, produce quenching hot tearing, causes workpiece to scrap, and quenchant temperature can not evenly be transmitted, easily affect metallographic structure and the hardness of workpiece.
Summary of the invention
The invention is intended to provide a kind of small-sized foundry goods quenching bath that can make the homogeneous temperature transmission of quenching.
A kind of small-sized foundry goods quenching bath, comprise pond body, body inside, pond is provided with casting loads basket, and described casting loads basket comprises mesh basket body and handle; Also comprise one and be positioned at worktable, servomotor and the leading screw that Chi Tishang puts, described servomotor is positioned on worktable, and the output shaft end of servomotor is drivingly connected with a leading screw, and described basket body is fixedly connected with and is arranged on leading screw.
Further, described worktable comprises table top and bracing frame, and described leading screw comprises screw mandrel and nut, and support frame as described above is provided with slideway, also comprises sliding bar, and described sliding bar one end and nut are fixed, and the other end and slideway are slidably connected; Described handle is connected with sliding bar.
Further, be also provided with skim strainer in the body of described pond, described filter screen surrounding is provided with baffle plate, and baffle plate is connected with handle by union lever.
Further, described casting loads basket is 2.
Beneficial effect of the present invention is:
When quenching technology, directly foundry goods is placed in casting loads basket, then starts servomotor and drive leading screw to-and-fro movement thus drive the reciprocal up-and-down movement in the body of pond of casting loads basket.Pumping of basket body can drive quenching media motion in the body of pond, can prevent from forming steam film, contribute to the homogeneous temperature transmission of quenchant, the homogeneous temperature transmission of quenching can be made, thus ensure foundry goods equilibrium cooling, and avoid foundry goods under the state of Quench, produce quenching hot tearing, the situation causing workpiece to scrap occurs; Energy security deposit's phase constitution and hardness, can improve quenching effect.
After quenching, quenching media temperature is higher, and pond body has certain water vapour, is not easy to workman's pickup, and the present invention after quenching, when being risen to more than liquid level by basket body, can close servomotor, be convenient to workman's pickup.
Because cast outer surface can be stained with some impurity, can drop in quenching bath in the process of quenching, cause the work-ing life of quenching media lower, the setting of skim strainer, contribute to the cleaning of impurity in the body of pond, as long as regularly take out skim strainer, impurity inside it is cleaned out and puts back in quenching bath again; Just can extend the life-span of quenching media.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Embodiment 1
As depicted in figs. 1 and 2, a kind of small-sized foundry goods quenching bath, comprises pond body 1, and pond body 1 inside is provided with casting loads basket 2, and described casting loads basket 2 comprises mesh basket body 21 and handle 22; Also comprise one and be positioned at worktable, servomotor 3 and leading screw 4 that pond body 1 is put, described servomotor 3 is positioned on worktable, and the output shaft end of servomotor 3 is drivingly connected with a leading screw 4, and described basket body 21 is fixedly connected with and is arranged on leading screw 4; Described worktable comprises table top 51 and bracing frame 52, described leading screw 4 comprises screw mandrel 41 and nut 42, described screw mandrel 41 vertically distributes, and be connected with the output shaft end of servomotor 3, support frame as described above 52 is provided with slideway, also comprises the sliding bar 6 of arranged transversely, and sliding bar 6 is along uniform two of nut 42 circumference, described sliding bar 6 one end and nut 42 are fixed, and the other end and slideway are slidably connected; Handle 22 also arranges two, fixes respectively with a sliding bar 6.
During use, open servomotor 3, screw mandrel 41 namely can along with output shaft reciprocating rotation, because nut 42 is fixed by sliding bar 6, therefore nut 42 can not rotate along with screw mandrel 41, can only along screw mandrel 41 upwards, to-and-fro movement campaign downwards, thus drive casting loads basket 2 to pump, and quenching media fluctuated.
Embodiment 2
As shown in Figure 3 and Figure 4, the difference of the present embodiment and embodiment 1 is only, is also provided with skim strainer 7 in described pond body 1, and described filter screen 7 surrounding is provided with baffle plate 8, and baffle plate 8 is connected with handle 10 by union lever 9.Skim strainer 7 is than the undersized bottom the body of pond; Handle 10 is placed in pond body 1 edge, is convenient to filter residue 7 and nets taking-up.
Embodiment 3
The difference of the present embodiment and embodiment 2 is only, described casting loads basket 2 is provided with two.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
