Embodiment 1
[0130] (Proportional solenoid of Example 1)
[0131] First, the proportional solenoid 100 provided with the tubular fixed iron core 1 used in the solenoid of Example 1 was manufactured based on the manufacturing method of the above-mentioned embodiment. Specifically, the tubular member 101 was fabricated using a material for a composite magnetic body composed of a rod-shaped Fe—Cr—Ni—Mn—Al—C alloy (YEP-FA1, manufactured by Hitachi Metals). Then, use a thickness h with a thickness of 10mm in the Z-axis direction (refer to Figure 5 ) The high-frequency induction heating device 102 of the high-frequency coil 102b performs high-frequency heat treatment on the tubular member 101 of the fixed iron core 1 before heat treatment.
[0132] Specifically, the suction surface 11b of the tubular member 101 and the end of the high-frequency coil 102b on the suction surface 11b side (Z1 direction side) are separated by a distance t of 2.5 mm in the Z-axis direction (see Figure 5 ) way, co...
Embodiment 2
[0160] (Proportional solenoid of Example 2)
[0161] First, the proportional solenoid 100 provided with the tubular fixed iron core 1 used in the solenoid of Example 2 was manufactured based on the manufacturing method of the above-mentioned embodiment. In addition, in Example 2, the distance t between the suction surface 11b of the tubular member 101 for fixing the iron core and the end of the high-frequency coil 102b on the suction surface 11b side (Z1 direction side) before processing is separated in the Z-axis direction. The high-frequency coil 102b is arranged in the form of 1.5 mm. That is, the high-frequency coil 102b is arranged in such a manner that the center O1 in the Z-axis direction of the high-frequency coil 102b is located at the center in the Z-axis direction of the heating position H separated by a distance d of 6.5mm from the adsorption surface 11b of the tubular member 101 in the Z-axis direction. Coil 102b. In addition, after the heating temperature of th...
no. 3 example
[0169] Next, a third embodiment will be described. In the third example, with respect to the tubular fixed iron core 1 used in the solenoid of the second example above, the ratio of the fixed iron core 1 of the examples 3a and 3b in which the retention time or the retention temperature gradient is different is produced. Solenoid 100, and measure its attractive force curve.
[0170] (Proportional solenoids of Examples 3a and 3b)
[0171] The proportional solenoid 100 provided with the fixed core 1 of Example 3a was fabricated in the same manner as the tubular fixed core 1 used in the solenoid of Example 2 above except that the holding time was set to 9 seconds. In addition, except that the holding temperature rate indicating the holding temperature gradient was set to -10°C / sec, the same process was carried out as the tubular fixed iron core 1 used in the solenoid of Example 2 above to produce a fixed core 1 equipped with Example 3b. Proportional solenoid 100 for core 1.
