The outer shell is moved by a moving wheel. When performing the feeding operation, the furnace cover is first opened, and then the outer shell is aligned with the support. The material placement frame and the roller are placed on the outer shell. The material placement frame is pushed into the support inside the quenching furnace body through the connecting component, and then the connecting component is retracted to close the furnace cover for quenching. When performing the material removal operation, the material placement frame is hooked out of the quenching furnace body by extending the connecting component into the quenching furnace body, connecting the connecting component to the connecting block, and hooking the material placement frame out of the quenching furnace body to complete the material removal operation, thereby realizing the feeding and removing operations without the need for staff to perform, thereby avoiding injuries to staff.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 3 In this embodiment, a vacuum ion carburizing and quenching furnace includes a furnace body 11, a connecting block 16, and a furnace cover 12. The furnace cover 12 is clamped at the opening of the furnace body 11. A rotating component for hingedly connecting the furnace body 11 is provided on one side of the furnace cover 12. A connecting block 13 is fixedly connected to one side of the furnace cover 12. Both sides of the connecting block 16 are fixedly connected to limit blocks 17. A fixing component for fixing the limit blocks 17 is provided on the furnace body 11.

[0025] The connecting block 13 is connected to the connecting block 16 via a rebound assembly. A bracket 22 is fixedly connected to the bottom of the furnace body 11 , and a fixing plate 28 is fixedly connected to one side of the bracket 22 .

[0026] The rotating assembly includes a folding plate 20 and a mounting block 21. The folding plate 20 is fixedly connected to one side of the furnace cover 12, and the mounting block 21 is fixedly connected to one side of the furnace body 11. Two groups of fixed blocks 19 are fixedly connected to one side of the mounting block 21. The folding plate 20 is rotatably connected between the two groups of fixed blocks 19. The turntable 23 is pulled to rotate, and the turntable 23 drives the folding plate 20 to rotate between the two groups of fixed blocks 19, so that the staff can rotate and open the furnace cover 12.

[0027] The fixing assembly includes two groups of arc-shaped blocks 18, which are respectively fixedly connected to the top and bottom of the furnace body 11. One side of the limit block 17 slides with one side of the arc-shaped block 18. One side of the connecting block 16 is fixedly connected to a turntable 23. The limit block 17 is stuck in the notch of the arc-shaped block 18. Rotating the turntable 23 drives the connecting block 16 to rotate, so that the limit block 17 rotates along the arc surface of the arc-shaped block 18 to fix the furnace cover 12, thereby reducing the impact on the processing quality of the material due to excessive gaps.

[0028] The rebound assembly includes a spring 14 and a moving block 15. The spring 14 is connected to the side of the connecting block 13 away from the furnace cover 12. The moving block 15 is sleeved on the connecting block 13. One side of the moving block 15 is provided with a slide groove 27 for cooperating with the connecting block 13 to slide. The end of the spring 14 away from the connecting block 13 is connected to the side of the inner wall of the slide groove 27. The side of the moving block 15 away from the connecting block 13 is fixedly connected to the connecting block 16. The elastic force of the spring 14 is used to pop out the moving block 15, so that the connecting block 13 slides in the slide groove 27, driving the connecting block 16 to move, so that the limit block 17 is freed from the restriction of the arc block 18, and the connecting block 16 is rebounded, thereby driving the limit block 17 to reset, making it convenient to fix the furnace cover 12 again.

[0029] Two groups of guide grooves 24 are provided on the fixed plate 28, and two groups of universal wheels 25 are slidably connected in the guide grooves 24. The tops of the four groups of universal wheels 25 are fixedly connected to the same group of moving platforms 26. The materials to be processed are transported through the moving platforms 26, and the universal wheels 25 slide into the guide grooves 24, which can facilitate the transportation of the materials to be processed and reduce the workload of the staff.

[0030] The surface of the furnace cover 12 contacting the inner wall of the furnace body 11 is provided with a heat-resistant rubber layer. By providing the heat-resistant rubber layer, the gap between the furnace cover 12 and the furnace body 11 can be reduced.

[0031] The working principle of the present invention is as follows: when in use, first rotate the turntable 23 to drive the connecting block 16 to rotate. As the connecting block 16 rotates, the limit block 17 is driven to rotate on one side of the arc-shaped block 18. When it rotates to a blank position, the elastic force of the spring 14 is used to pop out the moving block 15, so that the connecting block 13 slides in the slide groove 27, driving the connecting block 16 to move, so that the limit block 17 is freed from the restriction of the arc-shaped block 18, and the turntable 23 is pulled to rotate. The turntable 23 drives the folding plate 20 to rotate between the two sets of fixed blocks 19, and the material to be processed is moved through the moving table 26. The material is conveyed so that the universal wheel 25 slides into the guide groove 24, and the material is placed in the furnace body 11. The movable platform 26 is pushed out, and the turntable 23 is pushed to close. The turntable 23 is pressed, and the turntable 23 squeezes the connecting block 16. The connecting block 16 squeezes the moving block 15 inward. The moving block 15 slides on the connecting block 13 and squeezes the spring 14, so that the limit block 17 is stuck in the notch of the arc-shaped block 18. The turntable 23 is rotated to drive the connecting block 16 to rotate, so that the limit block 17 rotates along the arc surface of the arc-shaped block 18, and the furnace cover 12 is fixed to reduce the impact on the processing quality of the material due to excessive gaps.
