Abstract
The utility model relates to a thermal treatment quenching device for a metal material, in particular to a novel quenching device applied to a medium-carbon alloy steel workpiece. The device comprises a hanger 1, hydraulic pump oil nozzles 2 and a quenching oil bath 3, wherein the hanger 1 is a cylindrical frame; a hanging rod is arranged on the upper surface of the hanger 1, and is used for hanging the workpiece; and a plurality of hydraulic pump oil nozzles 2 are arranged on the two sides of the quenching oil bath 3, and are used for extracting quenching liquid from the quenching oil bath 3 by utilizing a high-power hydraulic pump. Compared with the conventional quenching device, the utility model has the advantages that the novel quenching device is simple in structure, convenient to use and low in manufacture cost, and production efficiency is improved; and moreover, the quenching hardness of workpieces in the same furnace fluctuates within 3HRC, and is highly consistent, a scrap rate in a machining process is decreased, quality is ensured, and yield is improved.
Description
Technical field
The utility model relates to the heat treatment quenching device of metallic substance, more precisely a kind of Novel quenching device that is applicable to the medium carbon alloy steel workpiece.
Background technology
Material is the workpiece of medium carbon alloy steel, the difficult control of the homogeneity of hardening with stove, be that φ 12mm length is the engine starting shaft of 108mm such as diameter, high tempering (being modifier treatment) after requiring to quench, its hardness requirement 22～30HRC, direct oil quenching after workpiece being stacked in the box type heater heating, the changes in hardness scope is about 13HRC, though through with workpiece even interval and be lifted on the sealing and the homogeneous heating performance heat in the pit furnace preferably, and strictly control quench fluid temperature, after oil quenching is carried out in lifting, still there is the fluctuation of 10HRC with furnaceman's part, exceeds the scope of the 5HRC of requirement.Confirm through verification experimental verification, the workpiece that causes the larger reason of changes in hardness scope to be mainly to be lifted on the quenching frame bottom at first enters when quenching and carries out chilling in the hardening liquid, its hardness is higher, and the workpiece on middle part and top lags and enters in the hardening liquid, the temperature of itself is existing to descend, the upwards impact of rising hot steam when quenched by lower workpiece, temperature is accelerated again to descend, quench fluid temperature heats when the workpiece quenching of suspension bracket bottom, temperature rises again 5～10 ℃, this two-part workpiece is in entering hardening liquid the time, hardness can be along with upwards being progressively downward trend, during to the suspension bracket top, workpiece has been lower than the hardness that requires after the quenching, causes the hardness after the tempering also to have more unacceptable product.Want to solve the bad phenomenon that this from bottom to top hardness progressively reduces, must solve temperature and the quench fluid temperature of the workpiece when quenching.Though so that its temperature as far as possible evenly, and swings the quenching suspension bracket all around, avoid the selective hardening liquid temp higher and affect quenching hardness through adopting the strong spiral oar to stir hardening liquid, effect is barely satisfactory.Terms of settlement only has the height or quench simultaneously up and down of arranging of workpiece when reduce quenching, and arranges and greatly increases highly again cost but reduce workpiece when quenching, and inadvisable, and only having starts with from the method for quenching simultaneously up and down solves.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of Novel quenching device that is applicable to the medium carbon alloy steel workpiece is provided.
In order to achieve the above object, the utility model takes scheme as follows: a kind of Novel quenching device that is applicable to the medium carbon alloy steel workpiece, and it comprises suspension bracket, hydro-pump oil nozzle and oil quenching bath, described suspension bracket is the right cylinder framework, its upper surface is provided with peg, is used for hanging workpiece; The both sides of described oil quenching bath are provided with some hydro-pump oil nozzles, are used for extracting hardening liquid from oil quenching bath.
The upper surface of described suspension bracket is provided with hook, makes things convenient for the unsettled hook of suspension hook.
The utility model is according to the instant spray quenching principle of high frequency, adopt up and down while Cooling Quenching method, when the workpiece in the suspension bracket bottom enters oil sump, drop in temperature and the quench fluid temperature that its cooling causes being risen on the impact of quenching hardness from the cold-peace water vapor of suspension bracket middle and upper part workpiece effectively avoided in the hardening liquid simultaneously spray quenching from suspension bracket top that utilizes high-power hydraulic pump to extract from oil quenching bath.
Unusual effect of the present utility model: than existing quenching device, not only simple in structure, easy to use, low cost of manufacture, enhance productivity, and this device with the fluctuation range of furnaceman's part quenching hardness in 3HRC, consistence is fine, reduced the learies in the course of processing, guarantee quality, promoted output.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further elaborated.
Accompanying drawing 1 is the synoptic diagram of heat structure of the present utility model.
Among the figure 1, suspension bracket 2, hydro-pump oil nozzle 3, oil quenching bath.
Embodiment
A kind of Novel quenching device that is applicable to the medium carbon alloy steel workpiece as shown in Figure 1, it comprises suspension bracket 1, hydro-pump oil nozzle 2 and oil quenching bath 3, and described suspension bracket 1 is the right cylinder framework, and its upper surface is provided with peg, is used for hanging workpiece; The both sides of described oil quenching bath 3 are provided with some hydro-pump oil nozzles 2, and the work of hydro-pump oil nozzle 2 is to utilize high-power hydraulic pump to extract hardening liquid from oil quenching bath 3.
The upper surface of described suspension bracket 1 is provided with hook, makes things convenient for the unsettled hook of suspension hook.
During use, first with the workpiece suspension of required quenching on suspension bracket 1, secondly with suspension hook with suspension bracket 1 oil quenching bath 3 tops of slinging, and unsettled, then slowly suspension bracket 1 is fallen toward oil quenching bath 3 bottoms, when the workpiece in suspension bracket 1 bottom enters oil quenching bath 3, the hardening liquid that utilizes high-power hydraulic pump from oil quenching bath 3, to extract, hardening liquid is simultaneously ejection from the hydro-pump oil nozzle 2 of oil quenching bath 3 both sides, has effectively avoided drop in temperature and the quench fluid temperature that its cooling causes being risen on the impact of quenching hardness from the cold-peace water vapor of suspension bracket middle and upper part workpiece.
