が、上述のような炉中加熱では不適当であるとと
もにエネルギー効率が悪くなる。 When the hollow stabilizer is subjected to heat treatment such as hardening, tempering, annealing, etc., the hollow stabilizer is mainly held in a heating furnace and heated as in the case of the hollow stabilizer. Therefore, the heating time is long, and since it is a hollow material, it is easily deformed during heating, and scales are easily generated, resulting in severe roughness of the product. Furthermore, in the case of a stabilizer that is partially subject to high stress, it is sufficient to heat-treat only that part, but heating in a furnace as described above is not appropriate and energy efficiency deteriorates.

に設定される。 Hereinafter, the present invention will be explained with reference to the drawings. In Fig. 1, the main body 1 of the hollow stabilizer
integrally includes a base 2 that is attached to the vehicle body, an arm 3 whose tip is attached to the wheel, and a curved portion 4 that is interposed between the base 2 and the arm 3. It is formed from a suitable hollow material. In order to perform heat treatment only on the curved portion 4 where the highest stress generally occurs in the main body 1, the same portion 4 is heated.
When heating, electrodes 5 and 6 are attached to both sides of the curved portion 4 in the longitudinal direction as shown in the figure, and these electrodes 5 and 6 are connected to connection ends 8 and 9 of the power supply section 7, respectively. Then, from the power supply section 7 to the connection end 8 - electrode 5 -
The curved portion 4 is heated by energizing the closed circuit of the curved portion 4-electrode 6-connection end 9. Moreover, instead of applying electricity in parallel to the pair of curved parts 4, 4 as described above, a pair of electrodes 5, 5 are provided on the side of the base 2 with respect to the curved parts 4, 4 as shown in FIG. while short-circuiting and connecting some other electrodes 6, 6 located on the sides of the arms 3, 3 to the connecting ends 8, 9, respectively,
The curved portions 4, 4 may be energized in series. In any case, the heating temperature is set to a desired value by adjusting the current flowing through the power supply section 7, and the heating time is set to a desired value by controlling the current flowing time.

る。 In the above, the case where only the curved part 4 is heated has been explained, but if, for example, only the base 2 is heated, the electrode 6 is removed or the connection with the power supply part 7 is cut off, and the pair of electrodes is It is only necessary to change the connection of either one of the terminals 5 and 5 from the terminal 8 to the terminal 9. In addition, for example, when heating the base 2 and the curved parts 4, 4 at the same time, one electrode 5, 5 is removed or the connection with the power supply part 7 is cut off, and one of the other electrodes 6, 6 is turned off. All you have to do is change the connection from connection end 9 to connection end 8. In this case, by attaching the other electrodes 6, 6 to the tip of the arm 3, it becomes possible to heat the entire body. In addition, a desired portion can be heated to a desired temperature by appropriately setting the number and position of the electrodes.

くの優れた効果を奏することができる。 According to the present invention, as described above, at least a portion in the longitudinal direction is heated by direct energization, so that only the desired portion can be heated simply and easily, and compared to ordinary heating in a furnace, Heating time can be significantly shortened. Therefore, there is little decarburization, coarsening of crystal grains, deformation, etc., and there is almost no scale formation, so the surface is smooth and the quality level and durability can be significantly improved. In addition, it has good energy efficiency and can contribute to resource and energy conservation, and it can produce many excellent practical effects, such as making it possible to downsize the device and improving the working environment. .
