[0054] Working principle: in the work, the metal parts need to be placed in the upper end of the support plate 8, at this time the second motor 4 rotates to make the reciprocating screw rod 11 rotate, and then the second sliding block 10 moves in the second sliding groove 12, the second sliding block 10 drives the support column 5 to move, the support column 5 drives the horizontal column 7 to move, the horizontal column 7 drives the support plate 8 to move, the support plate 8 drives the metal parts to move, the support plate 8 moves to the left and contacts the right side of the processing table 9, at this time the support plate 8 cannot move to the left, the support column 5 continues to move to the left, and the push block 33 moves to the left, at this time the support plate 8 makes the first sliding block 38 move in the first sliding groove 51, and the first spring 36 is compressed, at this time the U-shaped plate 28 is located at the upper end of the horizontal column 7, the push block 33 moves to the left relative to the support plate 8, and then pushes the metal parts at the upper end of the support plate 8, so as to push the metal parts to the upper end of the processing table 9, then the second sliding block 10 drives the support column 5 to move to the right, so that the support plate 8 moves out of the inside of the processing furnace 1, when the metal parts are heat treated, at this time the support column 5 moves to the left, the first motor 19 drives the first rod 26 to rotate, the first rod 26 drives the first bevel gear 44 to rotate, the first bevel gear 44 drives the second bevel gear 29 to rotate, and then the second rod 27 rotates, the second rod 27 rotates to make the U-shaped plate 28 rotate to the left, and then the metal parts on the upper end of the processing table 9 are surrounded, then the support column 5 moves to the right and drives the U-shaped plate 28 to move, the U-shaped plate 28 pushes the metal parts to the upper end of the support plate 8, and the support plate 8 is reset under the action of the first spring 36, so that in the whole working process, the metal parts are transported by the U-shaped plate 28 and the support plate 8, and then the metal parts are put in and taken out, so that the metal parts are not easy to be clamped on the outside when they are heat treated, and then the original shape of the metal parts can be guaranteed, unnecessary deformation of the metal parts is avoided, and the effect of the device on the transportation of the metal parts is improved;

[0055] Further, when the support plate 8 moves to the left, the rotating rod 21 is driven to move, the rotating rod 21 drives the spur gear 20 to move, the spur gear 20 rotates under the action of the tooth block 14, at this time, the inner ring and the outer ring of the one-way bearing 25 are in a relative rotating state, and then the spur gear 20 rotates without driving the rotating rod 21 to rotate, and then the rotating rod 21 does not rotate when the metal piece is put into the processing furnace 1, when the support plate 8 moves to the right, the rotating rod 21 drives the spur gear 20 to move at this time, the inner ring and the outer ring of the one-way bearing 25 are in a locked state, and then the spur gear 20 drives the rotating rod 21 to rotate, the rotating rod 21 drives the knocking block 46 to rotate, the knocking block 46 contacts with the contact block 17, the contact block 17 drives the moving rod 47 to move, the moving rod 47 moves and compresses the fifth spring 53, when the contact block 17 is misaligned with the knocking block 46, the moving rod 47 is reset under the action of the fifth spring 53, and then the moving rod 47 drives the knocking block to move, and knocks the inner wall of the shell 15, so that when the metal piece is taken out, the knocking block is knocked by the moving rod 47, and then a certain vibration effect is generated, the outer skin and the debris generated during the surface processing of the metal piece are shaken off, pass through the leakage hole, and then enter the inside of the shell 15 for collection, so that dust pollution in the processing workshop is avoided, and the working environment is improved;

[0056] Further, the rotating rod 21 drives the L-shaped rod 50 to rotate, the upper end of the L-shaped rod 50 drives the limiting frame 16 to move, the limiting frame 16 drives the square slot plate 48 to move, and the square slot plate 48 moves stably under the limiting action of the cross rod 49, and moves left and right, the square slot plate 48 drives the metal piece to move, and then helps the outer skin and the debris on the surface of the metal piece to fall off, and improves the cleaning effect of the debris;

[0057] Further, when the U-shaped plate 28 rotates, the cleaning rod 42 is located at the upper end of the metal piece, and the metal piece moves left and right under the action of the cleaning rod 42, and the upper end of the metal piece is cleaned, it should be noted that the elastic coefficient of the third spring 43 is small, and then the metal piece will not be subjected to too much pressure, so that the effect of collecting the debris is further improved;

[0058] Further, when the metal piece moves left and right, the push block 33 is continuously pressed, the push block 33 moves right relative to the rectangular block 35, under the action of the fourth spring 34, the push block 33 continuously moves left and right, when the push block 33 moves right, the one-way valve 45 is in a closed state, thereby making the gas in the interior of the rectangular block 35 sprayed out through the spray head 40, thereby blowing off the debris on the upper end of the metal piece, when the push block 33 moves left relative to the rectangular block 35, at this time, the one-way valve 45 is in an open state, air can enter the interior of the rectangular block 35 quickly, in this way, when the metal piece moves left and right, by continuously pressing the push block 33, the skin and debris of the metal piece can be further removed through the air spraying of the spray head 40, the taking material effect is improved.

[0059] The above merely provides the preferred but not limiting embodiments of the present application. Any modification, equivalent replacement or change within the technical scope disclosed by the present application and the improvement concept thereof should be covered within the protection scope of the present application.
