Abstract
The utility model discloses a step shaft induction heating device, the device mainly include step shaft and profile modeling coil, and this device has designed a step shaft induction heating device based on electromagnetic induction heating's principle, carries out induction heating to the surface of step shaft, improves the intensity and the toughness of step shaft. Wherein the tip department of profile modeling coil in this device heating step shaft is equipped with the recess that the radius is R, has weakened the effect of tip effect for induction heating's surface is heated evenly, has improved heating surface quality. The value of R is related to the geometric dimension of the induction heating shaft section, so that the same profiling coil can be selected for the shaft sections with similar geometric dimensions, and the manufacturing cost of the device is reduced.
Description
Technical Field
The utility model relates to an application in induction heating device field, concretely relates to stepped shaft induction heating device.
Background
The stepped shaft is an important part in transmission machinery, and can bear large load and generate abrasion in the process of transmitting motion, receiving torsion and bending moment. Therefore, it is required to improve mechanical properties such as strength and toughness by a surface heat treatment process. The induction heating is used as a heat treatment technology, has the advantages of high heating speed, high efficiency, small heat loss, easy realization of automatic control and environmental protection, and is widely applied to the manufacturing industries of automobiles, petroleum pipelines, machine tools and the like in China. The stepped shaft is subjected to heat treatment by using induction heating, so that the production efficiency can be improved, and the stepped shaft is energy-saving and environment-friendly. However, as shown in fig. 2, when both the a surface and the B surface of the stepped shaft need to be quenched by heating, the temperature of the tip of the stepped shaft is much higher than that of the rest due to the tip effect, so that the stepped shaft is heated unevenly, and the strength of the stepped shaft is reduced, which causes heating defects.
Disclosure of Invention
To the problem, the utility model discloses reform transform the profile modeling coil to step shaft induction heating, at the tip part of profile modeling coil heating step shaft, designed a recess, reduce the effect of tip effect for the temperature distribution of whole induction heating part is even, improves the surperficial heat treatment quality of step shaft.
The utility model discloses mainly include the stepped shaft, take notched profile modeling coil, the stepped shaft clamping is on the lathe, the profile modeling coil is placed apart from 5-10mm departments of stepped shaft, just the profile modeling coil adopts hollow structure to be equipped with the recess that the radius is R at the most advanced of heating stepped shaft, profile modeling coil C end is water inlet termination power positive pole, profile modeling coil D end is delivery port termination power negative pole.
The radius of the shaft section of the stepped shaft is greater than or equal to 5 through induction heating, the radius R of the profiling coil groove is 5mm, the ratio of the length of the shaft section of the stepped shaft to the radius of the shaft section is less than 5 through induction heating, and the radius R of the profiling coil groove is 3 mm.
The utility model discloses the device includes following technical scheme:
when the stepped shaft is heated by induction, the water loop is firstly introduced into the profiling coil to play a cooling role, then the profiling coil is connected with the anode and the cathode of the power supply, the machine tool is started, and the power supply is turned on, so that the stepped shaft is heated in a rotating manner. Because the tip of the profiling coil at the heating stepped shaft is provided with the groove with the radius of R, the tip of the stepped shaft is heated and reduced, the tip effect is weakened, the A surface and the B surface which are quenched are heated uniformly, and the strength and the toughness of the stepped shaft are improved.
The utility model discloses the advantage and the positive effect that the device had:
the device carries out heat treatment on the stepped shaft by utilizing induction heating, so that the production efficiency can be improved, and meanwhile, the device is energy-saving and environment-friendly; and the profiling coil in the device is provided with the groove, so that the effect of the tip effect in the heating process can be weakened, the heating is uniform, and the strength and the toughness of the stepped shaft are improved.
Drawings
The device of the present invention will be further described with reference to the accompanying drawings.
FIG. 1 is an isometric view of a preferred embodiment of the device of the present invention;
fig. 2 is an assembly view of the stepped shaft and profile coils of a preferred embodiment of the device of the present invention.
In the attached drawings, 1, a stepped shaft; 2. a profiling coil; C. a water inlet end; D. a water outlet end.
Detailed Description
In the figure, a stepped shaft 1 is clamped on a machine tool, a copying coil 2 is placed at a position 5-10mm away from the stepped shaft, the copying coil 2 is of a hollow structure, a groove with the radius of R is arranged at the tip of the heating stepped shaft, the water inlet end C of the copying coil is connected with a positive electrode of a power supply, and the water outlet end D of the copying coil is connected with a negative electrode of the power supply.
When the length of the shaft portion of the induction heating stepped shaft 1 and the radius of the shaft portion are equal to or greater than 5, the radius R of the groove of the profiling coil 2 is equal to 5mm, and the ratio of the length of the shaft portion of the induction heating stepped shaft 1 to the radius of the shaft portion is less than 5, the radius R of the groove of the profiling coil 2 is equal to 3 mm.
When the stepped shaft 1 is heated by induction, a water loop is firstly introduced into the profiling coil 2 to play a cooling role, then the profiling coil 2 is connected with the anode and the cathode of a power supply, the machine tool is started, and the power supply is turned on, so that the stepped shaft 1 is heated in a rotating way. Because the tip of the profiling coil at the heating stepped shaft is provided with the groove with the radius of R, the tip of the stepped shaft 1 is heated less, the tip effect is weakened, the A surface and the B surface which are quenched are heated uniformly, and the strength and the toughness of the stepped shaft are improved.
