Abstract
The invention relates to a heat treatment quenching device for a metal material, and particularly relates to a novel quenching device applicable to a medium carbon alloy steel workpiece. The device comprises a hanging frame 1, hydraulic pump oil nozzles 2 and a quenching oil pool 3, wherein the hanging frame 1 is cylindrical, and a hanging rod is arranged on the upper surface of the hanging frame 1 and used for hanging a workpiece; multiple hydraulic pump oil nozzles 2 are arranged on the two sides of the quenching oil pool 3; the work of the hydraulic pump oil nozzles 2 is used for extracting the quenching liquid from the quenching oil pool 3 by use of a high-power hydraulic pump. Compared with the existing quenching device, the device provided by the invention has the advantages of simple structure, convenience in use and low manufacturing cost, and improves the production efficiency; moreover, the fluctuation range of the quenching hardness of the same-furnace workpieces is controlled within 3HRC, the consistency is perfect, the discard quantity in the processing process is reduced, the quality is guaranteed, and the output is increased.
Description
Technical field
The present invention relates to the heat treatment quenching device of metallic substance, more precisely a kind of Novel quenching device that is applicable to medium carbon alloy steel workpiece.
Background technology
Material is the workpiece of medium carbon alloy steel, the more difficult control of homogeneity of hardening with stove, if diameter is the engine starting shaft that φ 12mm length is 108mm, high tempering (being modifier treatment) after requiring to quench, its hardness requirement 22～30HRC, direct oil quenching after workpiece being stacked in box type heater to heating, changes in hardness scope is in 13HRC left and right, though through by workpiece even interval and be lifted on sealing and the good pit furnace of homogeneous heating performance in heat, and strictly control quench fluid temperature, lifting is carried out after oil quenching, with furnaceman's part, still there is the fluctuation of 10HRC, the scope that exceeds the 5HRC of requirement.Through verification experimental verification, confirm, cause reason that changes in hardness scope is larger to be mainly to be lifted on the workpiece of quenching frame bottom to carry out chilling first enter hardening liquid when quenching in, its hardness is higher, and the workpiece on middle part and top lags and enters in hardening liquid, the existing institute of temperature of itself declines, the impact of the rising hot steam that makes progress while quenched by lower workpiece, temperature is accelerated again to decline, 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 time, hardness can be along with being upwards progressively downward trend, during to suspension bracket top, workpiece is lower than the hardness that requires after quenching, cause the hardness after tempering also to have more unacceptable product.Want to solve the bad phenomenon that this hardness from bottom to top progressively reduces, must solve temperature and the quench fluid temperature of the workpiece while quenching.Though so that its temperature as far as possible evenly, and swings quenching suspension bracket all around, avoid selective hardening liquid temp higher and affect quenching hardness through adopting strong spiral oar to stir hardening liquid, effect is barely satisfactory.Terms of settlement only has the height or simultaneously quench up and down of arranging of workpiece while reduce quenching, but reduce workpiece while quenching, arranges and greatly increases highly again cost, and inadvisable, only from the method for quenching up and down simultaneously, start with and solve.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of Novel quenching device that is applicable to medium carbon alloy steel workpiece is provided.
In order to achieve the above object, the present invention takes scheme as follows: a kind of Novel quenching device that is applicable to medium carbon alloy steel workpiece, and it comprises suspension bracket, hydro-pump oil nozzle and oil quenching bath, described suspension bracket is right cylinder framework, its upper surface is provided with peg, for hanging workpiece; The both sides of described oil quenching bath are provided with some hydro-pump oil nozzles, for extracting hardening liquid from oil quenching bath.
The upper surface of described suspension bracket is provided with hook, facilitates the unsettled hook of suspension hook.
The present invention is according to the instant spray quenching principle of high frequency, adopt while Cooling Quenching method up and down, when the workpiece in suspension bracket bottom enters oil sump, the hardening liquid spray quenching simultaneously from suspension bracket top that utilizes high-power hydraulic pump to extract from oil quenching bath, has effectively avoided its cooling temperature causing being declined and the impact of quench fluid temperature rising on quenching hardness from cold-peace water vapor of suspension bracket middle and upper part workpiece.
Unusual effect of the present invention: 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further elaborated.
The schematic diagram that accompanying drawing 1 is heat structure of the present invention.
1. suspension bracket 2. hydro-pump oil nozzle 3. oil quenching baths in figure.
Embodiment
A kind of Novel quenching device that is applicable to 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 right cylinder framework, and its upper surface is provided with peg, 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, facilitates the unsettled hook of suspension hook.
During use, first by the workpiece suspension of required quenching on suspension bracket 1, secondly with suspension hook by 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 to extract from oil quenching bath 3, hardening liquid is ejection simultaneously from the hydro-pump oil nozzle 2 of oil quenching bath 3 both sides, has effectively avoided its cooling temperature causing being declined and the impact of quench fluid temperature rising on quenching hardness from cold-peace water vapor of suspension bracket middle and upper part workpiece.
