[0002] The flange heating and feeding device is a special equipment used to transport flange blanks to a medium-frequency induction furnace for heating treatment. Currently, existing flange heating and feeding equipment typically includes a medium-frequency induction furnace and a raw material placement platform. During use, the operator moves the flange blank to be heated from the raw material placement platform to the feed port of the medium-frequency induction furnace. The operator then manually pushes the flange blank into the furnace heating chamber, making it easier to heat the flange blank. Existing flange heating and feeding equipment requires operators to manually feed the flange blanks, which is time-consuming and labor-intensive. Summary of the Invention

The overflow valve 633 is installed on the second connecting pipe 632.

[0043] When the sliding frame 21 slides upward, it compresses the air bladder 612. The liquid inside the air bladder 612 flows through the first connecting pipe 623 into the rodless cavity of the adjusting telescopic rod 622, increasing the volume of the rodless cavity. The movable end of the adjusting telescopic rod 622 extends, driving the guide plate 621 to rotate. The two sets of guide plates 621 form a guide channel.

[0044] The implementation principle of the flange heating automatic feeding device in this application embodiment is as follows: In use, the flange blank slides along the sliding plate 11 to the stop 111. The controller 252 drives the rotary cylinder 411 to work. The rotary cylinder 411 drives the flipping plate 412 to rotate. The bearing plate 413 lifts the flange blank, and the flange blank rolls onto the transfer plate 23. The partition plate 243 prevents the flange blank from falling during the flipping process.

[0045] When the flip plate 412 rotates, the third spring 422 resets and drives the movable end of the drive telescopic plate 421 to extend. The liquid in the plate cavity of the drive telescopic plate 421 flows through the pipe to the plateless cavity of the limit telescopic plate 423. The movable end of the limit telescopic plate 423 extends, and the flange blank on the sliding plate 11 is not easy to slide to the stop 111.

[0046] When the flip plate 412 is reset, the flip plate 412 squeezes the movable end of the drive telescopic plate 421, and the liquid in the non-plate cavity of the limit telescopic plate 423 flows through the pipe into the plate cavity of the drive telescopic plate 421. The movable end of the limit telescopic plate 423 retracts, and the flange blank on the sliding plate 11 slides to the stop block 111.

[0047] When the controller 252 drives the rotary cylinder 411 to reset, the controller 252 drives the movable end of the lifting cylinder 51 to extend. The movable end of the lifting cylinder 51 drives the first pulley 52 to move synchronously. The wire rope 54 passes around the first pulley 52 and the second pulley 53 in sequence. The wire rope 54 pulls the sliding frame 21 to slide in the vertical direction, and the flange blank on the transfer plate 23 is lifted to the inlet of the medium frequency induction furnace 31.

[0048] When the sliding frame 21 slides upward, it compresses the air bladder 612. The liquid inside the air bladder 612 flows through the first connecting pipe 623 into the rodless cavity of the adjusting telescopic rod 622. The movable end of the adjusting telescopic rod 622 extends, driving the guide plate 621 to rotate. The two sets of guide plates 621 form a guide channel. When the movable end of the adjusting telescopic rod 622 extends to its limit position, the liquid inside the air bladder 612 flows through the first connecting pipe 623, the second connecting pipe 632, and the overflow valve 633 into the rodless cavity of the supporting telescopic rod 631. The movable end of the supporting telescopic rod 631 extends and slides to the bottom of the first connecting plate 22 and the second connecting plate 24. The movable ends of the two sets of supporting telescopic rods 631 respectively support the first connecting plate 22 and the second connecting plate 24.

[0049] When the flange blank on the transfer plate 23 moves to the medium frequency induction furnace 31, the first spring 221 and the second spring 241 are reset. The controller 252 drives the movable end of the lifting cylinder 51 to retract. The lifting cylinder 51 drives the sliding frame 21 to slide downward through the wire rope 54. When the first connecting plate 22 and the second connecting plate 24 slide to the support telescopic rod 631, the air bag 612 is fully reset, and the movable end of the support telescopic rod 631 is reset, making it easy for the sliding frame 21 to be reset.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
