Abstract
The utility model discloses an induction heating coil for a transverse plane, comprising a hollow induction ring, and two cooling water pipes which are connected with the induction ring. The induction heating coil for a transverse plane is characterized in that the cross section of the induction ring is oval-shaped. The induction heating coil for transverse plane can uniformly heating the surface of a workpiece, and can improve the quenching quality.
Description
Technical field
The utility model relates to a kind of load coil for end face.
Background technology
When the end face of part was quenched, adopting induction hardening was a kind of mode preferably wherein, and existing load coil comprises the induction coil 5 of hollow, two cooling water pipes 6 that link to each other with induction coil 5 as shown in Figure 1, and the cross section of induction coil 5 is rectangle; During use, one end face of the induction coil 5 of energising is needed the end face of heating near workpiece 7, the magnetic line of force that induction coil 5 forms produces eddy current in the 7 end faces induction of workpiece, to heat this end face, but the shortcoming of this load coil is that the heat temperature raising of end face is inhomogeneous, hardness after causing quenching is also inhomogeneous, because the intensity of the eddy current that forms at workpiece end face depends on the density of line of magnetic force of induction coil 5, and induction coil 5 density of line of magnetic force on the corner is maximum, density of line of magnetic force at the middle part is minimum, therefore very fast in the outer collar region heating of workpiece end face, slower in centre heating, the direction that is to say heat transfer is to heat to the center from the outer ring, when the outer ring regional temperature reaches requiring of quenching technical, the central area temperature is inadequate, causes product defective; When position, center temperature reached technological requirement, outer ring regional temperature superelevation caused product rejection, and particularly the centre of some workpiece also is connected with cylinder, and cylinder itself can absorb heat, and more easily causes the end face non-uniform temperature.
The utility model content
The purpose of this utility model is for the prior art above shortcomings, and a kind of load coil for end face is provided, and it can with the surface of the work homogeneous heating, improve the quenching quality.
For achieving the above object, a kind of load coil for end face of the present utility model comprises the induction coil of hollow, two cooling water pipes that link to each other with induction coil, it is characterized in that the cross section of described induction coil is for oval.
The utility model is because the cross section of induction coil is oval, density of line of magnetic force at the elliptic end place is maximum, during use, induction coil is placed the medium position of workpiece end face, so that the density of line of magnetic force at middle part is greater than the density of line of magnetic force of outer ring, the direction of conducting heat is to conduct heat to both sides from the middle part, can with the surface of the work homogeneous heating, improve the quenching quality.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
To shown in Figure 4, should be used for the load coil of end face such as Fig. 2, and comprise the induction coil 1 of hollow, two cooling water pipes 2 that link to each other with induction coil 1, the cross section of described induction coil 1 is oval.
The utility model is because the cross section of induction coil 1 is oval, density of line of magnetic force at the elliptic end place is maximum, during use, as shown in Figure 5, induction coil 1 is placed the medium position of workpiece 3 end faces, so that the density of line of magnetic force at end face middle part is greater than the density of line of magnetic force of outer ring, the direction of heat transfer is to conduct heat to both sides from the middle part, can with the surface of the work homogeneous heating, improve the quenching quality.
