[0034] Reference Figure 1-Figure 3 The clamping assembly 5 includes a disc 52, a slide groove 53 is provided on the top of the disc 52, and the slide grooves 53 are arranged in four groups in a circular array. The inner wall of the slide groove 53 is slidably connected with a clamping rod 51, and a buckle is provided at the bottom of the clamping rod 51. The clamping rod 51 is arranged in four groups in a circular array. Through the sliding effect of the clamping rod 51, the clamping rod 51 contacts the inner wall of the tubular forging, thereby clamping and fixing the tubular forging. The top of the clamping rod 51 is hinged with an articulated rod 54, and the articulated rod 54 is arranged in four groups in a circular array. The hinged rod 54 is driven to slide along the inner wall of the slide groove 53 by the moving effect of the hinged rod 54. The left end of the hinged rod 54 is hinged with a connecting rod 55. There are four groups of connecting rods 55 distributed in a circular array. The hinged rod 54 is driven to move by the rotation effect of the connecting rod 55. The left end of the connecting rod 55 is fixedly connected with a rotating shaft 56. The inner wall of the top end of the rotating shaft 56 is provided with a limiting component 58. The rotating shaft 56 is limited by the limiting component 58, so that the four groups of clamping rods 51 remain fixed.

[0035] Reference Figure 2 and Figure 4 The assembly and disassembly component 6 includes a top cover 61. By moving the top cover 61 downward, the top cover 61 can close the top opening of the heating furnace 2, thereby preventing the loss of heat in the heating furnace 2. A square groove 62 is provided on the front of the top cover 61. The square groove 62 is symmetrically distributed in two groups. The front inner wall of the disc 52 is elastically connected with a wedge block 64 through a spring 63. The spring 63 and the wedge block 64 are symmetrically distributed in two groups. Through the elastic force of the spring 63, the wedge block 64 always maintains a clamping effect with the square groove 62 when not affected by external force, thereby limiting the disc 52.

[0036] Reference Figure 2 and Figure 5The limiting component 58 includes a collar 583, the outer wall of the collar 583 is provided with a card slot 584, and the card slots 584 are distributed in multiple groups in an annular manner. The multiple groups of card slots 584 are used to achieve card connection effects with the card block 581 at different positions, thereby achieving a limiting effect on the rotating shaft 56 at different positions. The inner wall of the top end of the rotating shaft 56 is elastically connected with the card block 581 through a limiting spring 582. Through the elastic force of the limiting spring 582, the card block 581 always maintains a card connection effect with the card slot 584 when not affected by external force, thereby limiting the rotating shaft 56.

[0037] Reference Figure 1 and Figure 2 A cover plate 57 is fixedly connected to the top of the disk 52, and the fixing effect of the cover plate 57 prevents the cover plate 57 from falling off. The outer periphery of the disk 52 is plugged into the inner wall of the top cover 61, and the outer periphery of the cover plate 57 is plugged into the inner wall of the top cover 61. Through the plugging effect of the top cover 61, the disk 52 and the cover plate 57, the disk 52 and the cover plate 57 are installed on the top cover 61. The outer periphery of the rotating shaft 56 is rotatably connected to the top inner wall of the cover plate 57, and the outer periphery of the rotating shaft 56 is rotatably connected to the inner wall of the collar 583. Through the rotation effect of the rotating shaft 56, the four groups of connecting rods 55 are driven to rotate at the same time.

[0038] Reference Figure 1 and Figure 2 The top of the top cover 61 is fixedly connected to the output end of the hydraulic cylinder 4. The fixing effect of the top cover 61 prevents the top cover 61 from falling off. One end of the spring 63 is fixedly connected to the front inner wall of the disk 52, and the other end of the spring 63 is fixedly connected to the outer wall of the wedge block 64. The fixing effect of the spring 63 keeps the wedge block 64 fixed to prevent the wedge block 64 from falling off.

[0039] Reference Figure 2 and Figure 5 The bottom of the collar 583 is fixedly connected to the top of the cover plate 57, and the fixing effect of the collar 583 prevents the collar 583 from falling off. One end of the limit spring 582 is fixedly connected to the inner wall of the top end of the rotating shaft 56, and the other end of the limit spring 582 is fixedly connected to the outer wall of the block 581. The fixing effect of the limit spring 582 keeps the block 581 fixed to prevent the block 581 from falling off.

[0040] Reference Figure 2 The outer wall of the wedge block 64 is slidably connected to the front inner wall of the disc 52. Through the sliding effect of the wedge block 64, the wedge block 64 and the square groove 62 are engaged or released. The outer wall of the wedge block 64 is engaged with the inner wall of the square groove 62. Through the engaging effect of the wedge block 64 and the square groove 62, the top cover 61 limits the disc 52.

[0041] Reference Figure 5The outer wall of the block 581 is slidably connected to the top inner wall of the rotating shaft 56. Through the sliding effect of the block 581, the block 581 and the slot 584 are engaged or released. The outer wall of the block 581 is engaged with the inner wall of the slot 584. Through the engagement effect of the block 581 and the slot 584, the ring 583 limits the rotating shaft 56.

[0042] Working principle: When the tubular forging needs to be heat treated, the staff will sleeve the tubular forging on the outer wall of multiple groups of clamping rods 51, and the buckle at the bottom of the clamping rod 51 will contact the bottom of the tubular forging to support the tubular forging. The staff will press the block 581 to release the clamping effect of the block 581 with the slot 584, and at the same time release the limiting effect on the rotating shaft 56. The staff will rotate the rotating shaft 56 to drive the four groups of connecting rods 55 to rotate at the same time, thereby driving the four groups of hinged rods 54 to move at the same time, so that the four groups of clamping rods 51 slide along the inner wall of the slide groove 53 toward the outside of the disc 52, so that the four groups of clamping rods 51 contact the inner wall of the tubular forging, thereby clamping and fixing the tubular forging.

[0043] After the tubular forging is clamped, the clamping block 581 is released, so that the clamping block 581 is clamped with the clamping groove 584 under the elastic force of the limit spring 582, and the rotating shaft 56 is limited at the same time, so that the four groups of clamping rods 51 remain in a fixed clamping state, and the staff plugs the cover plate 57, the disc 52 and the top cover 61, so that the wedge block 64 is clamped with the square groove 62 under the elastic force of the spring 63, and the disc 52 is limited at the same time, so that the disc 52 and the cover plate 57 are installed in the top cover 61, and the staff starts the hydraulic cylinder 4 to drive the top cover 61 to move downward, thereby driving the tubular forging to move to the inside of the heating furnace 2, and the top cover 61 closes the top opening of the heating furnace 2, and the heating furnace 2 is started, so as to perform heat treatment on the tubular forging.

[0044] When the heat treatment of the tubular forging is completed, the staff closes the heating furnace 2 and starts the hydraulic cylinder 4 to move upward, so that the top cover 61 drives the disc 52 to move upward, and the tubular forging is moved out of the heating furnace 2. The staff cools the tubular forging after the heat treatment. When the cooling is completed, the staff presses the wedge block 64 to release the clamping effect of the wedge block 64 on the square groove 62, and at the same time releases the limiting effect on the disc 52, so that the disc 52 and the cover plate 57 can be removed, thereby facilitating the staff to disassemble and replace the tubular forging.
