Through a series of structural settings, this utility model can adjust the height of the entire device according to the height of the feed inlet of the heat treatment furnace, thus making it suitable for feed inlets of heat treatment furnaces of different heights. It can also lift the pressed steel plate and push the material in the feeding operation through electric drive, completely eliminating the need for manual handling and effectively reducing labor intensity.

[0016] Working principle: When feeding the pressed steel plate, the entire device is placed at the feed inlet of the heat treatment furnace. The height of the pusher plate 11 is adjusted in advance according to the height of the feed inlet of the heat treatment furnace. During adjustment, the four first electric telescopic rods 1 are opened synchronously by the first synchronous control switch 16. The output shafts of the four first electric telescopic rods 1 simultaneously drive the U-shaped seat 2 to move upward. The U-shaped seat 2 drives the pusher plate 11 to move upward through the first multi-stage electric telescopic rod 12. When the pusher plate 11 moves upward until its bottom is flush with the bottom inner wall of the feed inlet of the heat treatment furnace, the four first electric telescopic rods 1 are closed. Next, the stacked pressed steel plates to be heat-treated are placed under the U-shaped base 2 using an external crane. Then, the height of the two support plates 10 is adjusted according to the bottom position of the uppermost pressed steel plate. During adjustment, the two second multi-stage electric telescopic rods 4 are opened in the forward direction via the second synchronous control switch 17. The output shafts of the two second multi-stage electric telescopic rods 4 simultaneously drive the lifting plate 3 upward. The lifting plate 3 drives the mounting box 6 upward via the two connecting plates 5. The mounting box 6 then drives the two support plates 10 upward via the two screws 7 and two clamping plates 8. When the support plates 10 move upward until their tops are flush with the bottom of the uppermost pressed steel plate, the two second multi-stage electric telescopic rods 4 are closed. Then, the drive motor 15 is opened in the forward direction via the wireless remote control switch operated by the external remote control. The output shaft of the drive motor 15 drives the second bevel gear 14 to rotate. The second bevel gear 14 drives the meshing first bevel gear 13 to rotate. The first bevel gear 13 drives the two screws 7 to rotate, opening the clamping plates... Under the action of the threaded holes on 8, the two screws 7 rotate, driving the two clamping plates 8 to move closer to each other on the two guide rods 9. The two clamping plates 8 drive the two support plates 10 to gradually insert into the bottom of the uppermost pressing steel plate. When the two clamping plates 8 contact the two sides of the pressing steel plate on their respective sides, the drive motor 15 is turned off, and the two second multi-stage electric telescopic rods 4 continue to open in the forward direction, so that the two support plates 10 continue to move upward. The two support plates 10 and the two clamping plates 8 simultaneously drive the pressing steel plate to move upward. When the bottom of the pressed steel plate is flush with the bottom of the pusher plate 11, the two second multi-stage electric telescopic rods 4 are closed and the first multi-stage electric telescopic rod 12 is opened in the forward direction. The output shaft of the first multi-stage electric telescopic rod 12 drives the pusher plate 11 to move forward and push the pressed steel plate forward, so that the pressed steel plate moves forward into the feed port of the heat treatment furnace, thereby completing the feeding operation. Moreover, the pressing steel plate is lifted and pushed by electric drive, which completely eliminates the need for manual handling, thereby effectively reducing labor intensity. After one pressed steel plate is loaded, when loading the next pressed steel plate, the drive motor 15 is first started in reverse. Similarly, the movement process of the drive motor 15 is the opposite of that of the forward start, so that the two clamping plates 8 and the two support plates 10 all change to move away from each other. When the distance between the two support plates 10 is greater than the width of the pressed steel plate, the drive motor 15 is turned off, and then the two second multi-stage electric telescopic rods 4 are started in reverse. Similarly, the movement process of the two second multi-stage electric telescopic rods 4 is the opposite of that of the forward start, so that the two support plates 10 change to move downward. When their tops are flush with the bottom of the pressed steel plate, the drive motor 15 can be started again in the forward direction to clamp and lift the pressed steel plate for subsequent loading operations.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
