[0028] Furthermore, each placement block 201 is symmetrically provided with a plurality of openings, each of which is connected to the circular groove, and hot and humid air enters the circular groove from the openings.
[0029] The present invention also provides a coil disk precision machining dedicated tunnel furnace placement processing technology, including the following structural specific steps: S1: Place the wound coil disk body 202 into the circular groove of the placement block 201, place the pressing block 203 on the upper end of the coil disk body 202, and place the placement block 201 with the coil disk body 202 on the metal conveyor mesh belt 102. At this time, the pressing block 203 is directly below the corresponding lower pressing plate 215d, and the first telescopic cylinder 215b is started. The telescopic end of the first telescopic cylinder 215b drives the first connecting plate 215c and the lower pressing plate 215d to move downward. The lower pressing plate 215d moves downward and presses on the pressing block 203. Under the action of the spring 216j, the inclined block 216a retracts. When the pressing block 203 is pressed on the coil disk body 202, the spring 216j returns to its original state, and the inclined block 216a enters the insertion port to fix the pressing block 203. S2: The placement block 201 with the coil disk body 202 is placed into the tunnel furnace body 101 through the metal conveyor mesh belt 102. The hot and humid air generated by the circulating fan 105 and the humidifier 106 fixes the coil disk body 202. The reduction motor 206 is started. The output end of the reduction motor 206 drives the first rotating rod 207 to rotate. The first rotating rod 207 is driven by the first bevel gear 208a, the second bevel gear 208b, the rotating rod 208c, the third bevel gear 208d and the fourth bevel gear. The wheel 208e drives the second rotating rod 209 to rotate, and the first rotating rod 207 and the second rotating rod 209 drive the first fan blade 210 to rotate. The first fan blade 210 sucks the hot and humid air from the opening into the circular groove and blows it upward. The hot and humid air moves upward along the No. 1 vortex ventilation port 212 on the guide plate 211, and the hot and humid air passes through the No. 2 vortex ventilation port 213 and the junction of the electromagnetic coil 202-2. The electromagnetic coil 202-2 is fully in contact with the hot and humid air, and then the hot and humid air passes through the No. 3 vortex ventilation port 214 and enters the cavity; S3: When the first rotating rod 207 and the second rotating rod 209 rotate, the vertical rod 301 is driven to rotate through the fixed rod 303a, the gear ring 303b and the transmission gear 303c, and the vertical rod 301 drives the second fan blade 302 to rotate. The hot and humid air in the cavity passes into the circular groove through the connecting pipe 305 and the connecting port, and is blown into the bottom of the first fan blade 210 under the action of the guide plate 304. The first fan blade 210 blows it upward together with the hot and humid air entering from the port to solidify the electromagnetic coil 202-2. The hot and humid air is continuously sucked into the circular groove by the first fan blade 210, and the hot and humid air entering the cavity is sucked into the circular groove again under the action of the second fan blade 302, and is blown upward again to solidify the electromagnetic coil 202-2. The hot and humid air is concentrated, thereby improving the solidification effect of the electromagnetic coil 202-2. S4: When the placement block 201 with the coil disk body 202 is moved out of the tunnel furnace body 101, the second telescopic cylinder 217b is started, and the telescopic end of the second telescopic cylinder 217b drives the second connecting plate 217c and the second tooth plate 217d to move downward, and the upper gear 216g on the placement block 201 is meshed with the second tooth plate 217d. The placement block 201 continues to move, and the upper gear 216g and the connecting rod 216f rotate. The rectangular block 216c, the rectangular plate 216i, the connecting block 216b and the inclined block 216a can be driven to move through the first gear 216e and the first tooth plate 216d. The inclined block 216a is moved out of the insertion port, which facilitates the removal of the pressing block 203 from the placement block 201, and then facilitates the removal of the solidified coil disk body 202.
