[0047] Example 3

[0048] like Figures 4-5As shown, the present invention proposes a tempering furnace for preventing the stacking of grinding balls. Compared with Embodiment 1 and Embodiment 2, this embodiment also includes a flipping component and a uniform dispensing mechanism.

[0049] The flipping assembly includes a motor 501, a rotating shaft 502, and a rotating roller 503. The motor 501 is located on the outside of the tempering furnace body 1, the rotating shaft 502 is located at the output end of the motor 501, and the rotating roller 503 is located on the outside of the rotating shaft 502. Multiple protrusions are evenly arranged on the outside of the rotating roller 503, which can increase the friction and thus drive the grinding ball to rotate more stably. There are three motors 501, which are evenly arranged. When the motor 501 is started, the motor 501 drives the rotating shaft 502 to rotate, and the rotating shaft 502 drives the rotating roller 503 to rotate.

[0050] The uniform dispensing mechanism includes a second fixing block 706, a pressing plate 701, a connecting block 703, a handle 704, a limiting hole 705, and a connecting assembly. The second fixing block 706 is disposed on the side of the placement plate 702, and the pressing plate 701 is rotatably disposed on the second fixing block 706. The inner side of the pressing plate 701 is provided with limiting holes 705, which are evenly arranged on the pressing plate 701 and correspond one-to-one with the placement frame 712. Both the limiting holes 705 and the placement frame 712 are located directly above the rotating roller 503. The handle 704 is disposed on the top of the pressing plate 701, and the connecting block 703 is disposed on the end of the placement plate 702 away from the second fixing block 706. The connecting assembly is disposed on the pressing plate 701 and is used to assemble the pressing plate 701 and the placement plate 702 together by pressing. The connecting assembly includes a pressure block 707, a sliding rod 708, a second spring 709, a locking block 710, and a locking groove 711. The second spring 709 is located on the top of the pressing plate 701. The sliding rod 708 is slidably disposed on the inner side of the pressing plate 701. The pressure block 707 is located on top of the sliding rod 708, and its bottom is connected to the top of the second spring 709. The locking block 710 is located at the bottom of the sliding rod 708. The locking groove 711 is located at the bottom of the placement plate 702. The locking groove 711 is cross-shaped, and its length is the same as that of the locking block 710. Pressing the pressure block 707... 7. At this time, the sliding rod 708 moves downward and the spring 709 retracts. The sliding rod 708 drives the locking block 710 to move downward and disengage from the slot 711. At this time, the sliding rod 708 can slide on the placement plate 702, thereby causing the pressing plate 701 to disengage from the placement plate 702. Then, the grinding ball is placed on the placement frame 712. After assembly, the pressing plate 701 is covered again. Then, the sliding rod 708 is pressed to make the locking block 710 engage in the slot 711, thereby fixing the position of each grinding ball. Then, the rotating roller 503 rotates to drive the grinding ball to rotate, so that the grinding ball is evenly heated and tempered.

[0051] In summary, when using this utility model, pulling the mating block 202 opens the rotating door 203. Then, gripping the handle 601 and rotating it causes the handle 601 to rotate. The handle 601 drives the rotating rod 602 to rotate, which in turn drives the rotating shaft 603 to rotate. The rotating shaft 603 drives the rotating gear 610 via the rotating gear 609. The rotating gear 610 drives the rotating gear 612 via the rotating shaft 611. The rotating gear 612 drives the rack 613 to move. The rack 613 drives the moving rod 614 to move within the fixed frame 616 via the slider 615. The moving rod 614 drives the placement plate 702 to rise via the connecting block 703 until it extends out of the tempering furnace body 1. At this point, the limiting rod 607 locks the rotating wheel 608. Then, pressing the pressing block 707 causes the sliding rod 708 to move downwards. The sliding rod 708 drives the locking block 710 to move downwards, thus... After disengaging from the slot 711, the sliding rod 708 can pass through the placement plate 702, thereby causing the pressing plate 701 to disengage from the placement plate 702. Then, the grinding balls are placed on the placement rack 712. After assembly, the pressing plate 701 is covered again, and then the sliding rod 708 is pressed to make the locking block 710 lock into the slot 711, thereby fixing the position of each grinding ball. Then, the grip rod 601 is reversed to drive the moving rod 614 to move down until the moving rod 614 moves to the bottom and then the main rotating wheel 608 is fixed in position by the limiting rod 607. Then, the motor 501 and the heating device 4 are started. The heating device 4 heats the tempering furnace body 1 for tempering, while the motor 501 drives the rotating shaft 502 to rotate, and the rotating shaft 502 drives the rotating roller 503 to rotate, thereby tumbling the grinding balls so that the grinding balls can be heated evenly.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
