[0038] As introduced in the background, the existing problems in the prior art, in order to solve the above technical problems, the application provides a quenching device and a quenching method for wind power fastener processing.

[0039] Embodiment one: please refer to Figures 1-12 A quenching device, comprising a fixed frame 1, the fixed frame 1 is sequentially provided with an electromagnet 4, a heating cylinder 2 and a quenching pool 3 from top to bottom, the electromagnet 4, the heating cylinder 2 and the quenching pool 3 are all on the same vertical line, the electromagnet 4 is used for adsorbing a bolt, the heating cylinder 2 is used for heating the bolt, and the quenching pool 3 is used for quenching the bolt;

[0040] The fixing frame 1 is further provided with a driving mechanism 5, the driving mechanism 5 comprises a placing plate 51, a driving assembly 52 and a rotating assembly 53, the placing plate 51 is used for placing the bolt to be processed, the driving assembly 52 is used for driving the electromagnetic iron 4 to move up and down, when the driving assembly 52 moves to the position above the heating cylinder 2, the driving assembly 52 can be connected with the placing plate 51 and can drive the placing plate 51 to move up synchronously with the electromagnetic iron 4, when the electromagnetic iron 4 moves up, the rotating assembly 53 can drive the electromagnetic iron 4 to rotate to the position above the placing plate 51;

[0041] The heating cylinder 2 is provided with a positioning mechanism 6, the positioning mechanism 6 comprises positioning blocks 61 and an unlocking assembly 62 which are distributed on the circumference of the heating cylinder 2, the positioning blocks 61 are used for positioning and bearing the bolt, the unlocking assembly 62 is used for driving the positioning blocks 61 to release the bearing of the bolt;

[0042] The quenching pool 3 is provided with a quenching basket 31, a turnover assembly 32 and a guide plate 33, the quenching basket 31 is used for bearing the bolt after being heated, the turnover assembly 32 is used for driving the quenching basket 31 to turn over, after the quenching basket 31 turns over, the guide plate 33 can collect the quenching liquid dropped from the quenching basket 31 and send it back to the quenching pool 3, and meanwhile, the guide plate 33 can collect the bolt after being quenched and the debris in the quenching basket 31.

[0043] In the initial state, the center of the electromagnet 4 is on the same vertical line as the center of the heating cylinder 2. When quenching the bolt, the bolt to be quenched is placed on the placement plate 51, and then the electromagnet 4 is driven upward by the driving assembly 52. When the electromagnet 4 moves upward, the placement plate 51 moves upward, and the bolt to be quenched moves upward. During the upward movement of the electromagnet 4, the rotating assembly 53 gradually rotates the electromagnet 4 to the placement plate 51, that is, the electromagnet 4 gradually becomes concentric with the placement plate 51. After the electromagnet 4 and the placement plate 51 are concentric, the placement plate 51 is in contact with the bottom surface of the electromagnet 4. At this time, the electromagnet 4 is started, so that the bolt on the placement plate 51 is adsorbed by the electromagnet 4. Then the electromagnet 4 is driven upward by the driving assembly 52, and the electromagnet 4 is separated from the placement plate 51. At this time, the placement plate 51 returns to the original position. Then the electromagnet 4 is driven downward by the driving assembly 52, and the electromagnet 4 gradually returns to the original position, that is, gradually returns to the position concentric with the heating cylinder 2. Then the electromagnet 4 drives the bolt to be quenched to move downward into the heating cylinder 2. Then the driving assembly 52 drives the bottom surface of the bolt to be in contact with the top surface of the positioning block 61 on the heating cylinder 2. Then, with the continuous operation of the driving assembly 52, the electromagnet 4 drives the bolt to continue to move downward. At this time, the bolt presses the positioning block 61. Then, under the cooperation of the electromagnet 4 and the positioning block 61, the bolt is clamped at both ends. Then the electromagnet 4 is turned off. Then the bolt is heated by the heating cylinder 2. After the bolt is heated to a specified temperature, the electromagnet 4 is driven downward by the driving assembly 52. At this time, the electromagnet 4 presses the bolt and the positioning block 61, and drives the bolt and the positioning block 61 to move downward. At this time, the unlocking assembly 62 operates, and the unlocking assembly 62 drives the positioning block 61 to separate from the bolt. Since the electromagnet 4 is turned off before the bolt is heated, and the bolt loses magnetism after being heated to austenite temperature, when the bolt and the positioning block 61 are separated, the bolt falls into the quenching basket 31 in the quenching pool 3 under the action of gravity. At this time, the quenching solution in the quenching pool 3 quenches the bolt. After quenching is completed, the electromagnet 4 is driven upward by the driving assembly 52. The electromagnet 4 drives the turnover assembly 32 to operate. The turnover assembly 32 drives the quenching basket 31 to turn over. The turnover of the quenching basket 31 drives the quenched bolt in the quenching basket 31 to turn over. When the turnover assembly 32 drives the quenching basket 31 to turn over the guide plate 33, the bolt, bolt debris and quenching solution in the quenching basket 31 will fall onto the guide plate 33 under the action of gravity. At this time, the quenching solution returns to the quenching pool 3 again through the guide of the guide plate 33, and the bolt and the bolt debris remain on the guide plate 33, thereby realizing the effect of automatically discharging the quenched bolt, and avoiding the problem that the bolt debris after quenching remains in the quenching pool 3.

[0044] Need to explain, in the electromagnet 4 bolt drive into the heating cylinder 2, and in the cooperation of positioning block 61 under the bolt clamping, turn off the electromagnet 4 and eliminate the residual magnetism of electromagnet 4 after closing by the reverse current demagnetization technology, while the electromagnet 4 is also provided with shielding structure, shielding structure can adopt reverse spiral magnetism ring, while the electromagnet 4 adopts high temperature special electromagnet.

[0050] In the initial state, the quenching basket 31 is in the state of being turned over, when the sliding seat 523 is driven to move downward by the lead screw 522, the turnover rack 322 moves downward with the sliding seat 523, the turnover rack 322 moves downward and contacts with the turnover gear 325, and with the downward movement of the sliding seat 523, the turnover rack 322 drives the turnover gear 325 to rotate, the turnover gear 325 drives the fixed worm 324 to rotate, the fixed worm 324 drives the fixed worm wheel 323 to rotate, the fixed worm wheel 323 drives the rotating shaft 321 to rotate, and the rotating shaft 321 drives the quenching basket 31 to turn over into the quenching pool 3, at this time, the heated bolts can fall into the quenching basket 31, and then the quenching solution in the quenching pool 3 quenches the bolts, after the quenching is completed, the sliding seat 523 is driven to move upward by the driving motor 521 and the lead screw 522, at this time, the turnover rack 322 drives the turnover gear 325 to rotate reversely, and for the same reason, at this time, the quenching basket 31 reverses, i.e. turns over from the quenching pool 3 to the above of the guide plate 33, at this time, the bolts, bolt scraps and quenching solution in the quenching basket 31 all fall onto the guide plate 33 under the action of gravity, and the quenching solution enters the quenching pool 3 again through the connection between the guide plate 33 and the quenching pool 3, and the filter screen 331 on the guide plate 33 blocks the bolts and bolt scraps.
