Example 2
In the technical solution described in the foregoing embodiment 1, because the distance between the outer circumferential surface B of the fixed drum and the third heating section 12C and along the seventh heating section is relatively large, and the distance between the first axial end surface C of the friction ring and the second heating section 12B and the sixth heating section 12f is relatively large, it is found through experiments that, although the first induction heating coil 10 can heat the brake disc, the heating effect of the third heating section 12C and along the seventh heating section on the outer circumferential surface B of the fixed drum and the inner circumferential surface B' of the fixed drum is not ideal, the heating effect of the second heating section 12B and the sixth heating section 12f on the first axial end surface C of the friction ring is not ideal, and in general, the first induction heating coil 10 with a product size can only heat the brake disc with one specification, but the brake disc with different specifications on the brake disc painting line is required to be heated, and each first induction heating coil 10 with different specifications is different, and each first induction heating coil 10 has a large difference in heating disc when heating the brake disc, therefore the first induction heating coil 10 is required to be independently replaced, and the brake disc with different specifications is required to be heated, and the brake disc with different specifications is also required to be heated, and the brake disc with different heating disc is not required to be heated. In order to have better heating effect, and make each face of brake disc can obtain comparatively close temperature rise (when induction heating, make the temperature rise of each face all be unable), add a second induction heating coil 20 in this embodiment, through two induction heating coils like this, can satisfy the heating of the brake disc of different specifications, and improve heating efficiency, the heating is even.
As shown in fig. 5, the second induction heating coil 20 includes a second lead portion 21 and a second induction heating body 22 connected to the second lead portion 21, the second induction heating body 22 has a body 23 and an extension 24 connected to the body 23 and arranged along the axial direction of the brake disc, a second recess 25 arranged along the radial direction of the brake disc is provided on the body 23, the second induction heating body 22 is moved along the radial direction of the brake disc to be heated, the friction ring 2 of the brake disc is entered into the second recess 25, and a prescribed distance L2 is provided between the brake disc and the second induction heating body 22.
As shown in fig. 6, for the position of the second induction heating coil 20, the preferred second induction heating body 22 is located in the yielding space 14 formed on the first heating body 12, so that the volume of the second induction heating coil 20 in this embodiment is smaller than that of the first induction heating coil 10, and meanwhile, the first induction heating coil 10 and the second induction heating coil 20 are both arranged on the same side of the conveying device for conveying the brake disc, so that not only is space saved, but also the two adjacent induction heating coils are relatively concentrated to perform induction heating on the brake disc, and the temperature rise of the brake disc is relatively faster.
As shown in fig. 5 and 6, the body 23 includes a tenth heating section 23a arranged along the Z axis, an eleventh heating section 23b arranged along the X axis, a twelfth heating section 23c arranged along the Y axis, a thirteenth heating section 23d arranged along the X axis, a fourteenth heating section 23e arranged along the Z axis, a fifteenth heating section 23f arranged along the X axis, a sixteenth heating section 23g arranged along the Y axis, a seventeenth heating section 23h arranged along the X axis, an eighteenth heating section 23i arranged along the Z axis, the tenth heating section 23a to the eighteenth heating section 23i being connected in series in order, and the extension 24 is connected to the tenth heating section 23a and the eighteenth heating section 23i, respectively.

After the heating sections are arranged according to the X axis, the Y axis or the Z axis, the second notch 25 is surrounded by the heating sections connected in series, when the second induction heating body 22 moves along the radial direction of the heated brake disc, a part of the friction ring 2 of the brake disc is entered into the second notch 25 and has a specified distance from the body 23, and the outer circumferential surface B of the fixed drum 1 of the brake disc has a specified distance from the extension part 24, so that the tenth heating section 23a and the eighteenth heating section 23i perform induction heating on the first axial end surface C of the friction ring; the twelfth heating section 23c and the seventeenth heating section 23h inductively heat the friction ring circumferential surface D; a fourteenth heating section 23E arranged along the Z axis induction heats the friction ring second axial end face E; the extension 24 heats the outer circumference B and the inner circumference B' of the stationary drum.
Obviously, the spacing between the tenth and eighteenth heating sections 23a, 23i and the friction ring first axial end face C is considerably shortened with respect to the spacing between the second and sixth heating sections 12b, 12f and the friction ring first axial end face C; and the distance between the outer circumferential surface B of the fixed drum and the extension 24 is also greatly shortened relative to the distance between the third heating section 12C and the seventh heating section 12g and the outer circumferential surface B of the fixed drum, so that the induction heating of the first axial end surface C and the outer circumferential surface B of the fixed drum can be compensated by adding the second induction heating coil 20, and the very close temperature rise of each surface of the brake disc can be obtained.
The induction heating coil is used for heating experiments on the brake disc, the distance L1 and the distance L2 are respectively selected to be a plurality of values, during the heating experiments, the power of the first induction heating coil and the second induction heating coil is set to be 80KW, the temperature of the brake disc is measured, the temperature of the outer axial end face A of the fixed drum, the temperature of the outer circumferential face B of the fixed drum and the temperature of the first axial end face C of the friction ring are selected to be the closest value (the temperature rise is explained to be relatively close), and therefore the optimal distance between each induction coil and the brake disc is obtained.
