The internal spiral quenching machine for the roll screen can effectively guarantee the quenching effect of a metal workpiece, realizes stable and continuous production, has stable product quality, a high degree of automation, a nearly zero equipment failure rate and considerable economic benefits, and is simple and convenient to manage, and the quality stability rate of products processed by the internal spiral quenching machine for the roll screen is increased by above 30% compared with that of products processed by other quenching equipment.
Description
Technical field
The utility model relates to metal quenching technology field, relates in particular to a kind of roll screen internal screw quenching press.
Background technology
The most of quenching apparatus that adopts of spherical, round bar shape metal works quenching heat treatment mode has two kinds; First kind is dragging track formula quenching press; The quenching process travelling speed of dragging track formula quenching press is slow; Can not eliminate the gas wall problem that workpiece forms on high temperature steel ball quenching top layer in the quenching process, quenching effect is undesirable, influences the stable of workpiece quality.With the steel ball quenching is example, and quench section site surface difference of hardness reaches 5～8HRC, and problems such as cracking or eccentric wear damage in use can take place.A kind of in addition is the drum type brake quenching press, and this mode is mainly used in the quenching that chemical reagent is a medium, and this medium has pollution and can not guarantee medium temperature, therefore needs to change this kind present situation, solves raising thermal treatment part overall performance from cooling and thermal treatment aspect.
Summary of the invention
The utility model provides a kind of roll screen internal screw quenching press to the above-mentioned deficiency that existing quenching apparatus exists.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of roll screen internal screw quenching press comprises internal screw quenching cylinder, reduction box, motor and slideway; Said slideway is arranged at an end of said internal screw quenching cylinder; Said reduction box is connected the other end of said internal screw quenching cylinder, and said reduction box links to each other with motor.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the inside center place of said internal screw quenching cylinder is provided with rotating shaft, is provided with screw-blade around said rotating shaft, and said screw-blade is arranged in the said internal screw quenching cylinder.
Further, the bottom of said internal screw quenching cylinder is arranged in the quenching bath.
Further, the rotating speed of said internal screw quenching cylinder is 450～600r/min.
The beneficial effect of the utility model is: the utility model roll screen internal screw quenching press is the quenching effect of security deposit's metal work-pieces effectively; Realize the production of steady and continuous, constant product quality, level of automation is high; Simple and convenient management; Equipment is so the rate of stopping is almost nil, and economic benefit is considerable, and the constant product quality rate of this device processes of process improves more than 30% than other quenching apparatus.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment roll screen internal screw quenching press.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; The utility model embodiment provides a kind of roll screen internal screw quenching press; Comprise internal screw quenching cylinder 1, reduction box 2, motor 3 and slideway 5; Said slideway 5 is arranged at an end of internal screw quenching cylinder 1, and said reduction box 2 is connected the other end of internal screw quenching cylinder 1, and said reduction box 2 links to each other with motor 3.The inside center place of said internal screw quenching cylinder 1 is provided with rotating shaft, is provided with screw-blade around said rotating shaft, and said screw-blade is arranged in the internal screw quenching cylinder 1.The bottom of said internal screw quenching cylinder 1 is arranged in the quenching bath 4.
Steel ball gets into the internal screw cylinder through slideway 5 by internal screw quenching cylinder 1 one sides; In quenching bath 4, carry out quench treatment; The rotating speed of internal screw quenching cylinder is depended in cool time control, and the steel ball cool time is 2 minutes 20 seconds～2 minutes and 40 seconds, and the rotating speed of internal screw quenching cylinder is controlled at 450～600r/min; Steel ball is realized the uniform hardening processing along with cylinder internal screw slideway advances.
Spherical, round bar shape metalwork is being in the quenching bath of medium with water, and through the rotation promotion of screw-blade, heat treated part speed with 32 meters/minute in quenchant travels forward; Travelling speed is fast; Realization is advanced, is swung, and realizes rotation in the time of the sieve nest revolution, and workpiece such as high temperature steel ball bump in the turbulent flow that stirs promotes blade and cylindrical shell; Eliminate the gas wall problem of quenching process; Thereby reached the purpose that improves quenching effect, with the steel ball be example surface hardness difference less than 3HRC, guarantee the inner quality of workpiece.
Certain factory is through using 1.5 ten thousand tons/year of this device processes forged steel balls, and steel ball gets into trade debtor and uses, and handles steel ball ball consumption than other quenching apparatus and reduces by 0.03 kilogram of/ton treatment capacity, and 143 tons of year saving steel balls are realized surplus the economic benefit 70 ten thousand yuan; 2 people because the high per tour of this automation degree of equipment is cut personnel, Spring Festival holidays less manpower takes 200,000 yuan; The equipment failure rate that operates steadily is extremely low, and shutdown event does not take place, and saves that spare part takes year, 320,000 yuan of upkeep costs; Thermal effectiveness is remarkable, and year reduces 65 tons in waste product, realizes 320,000 yuan of benefits, 1,540,000 yuan of overall economic efficiencies.Since this equipment comes into operation, safe and reliable, effect is obvious.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
