Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0017] A regenerative forging heating furnace body, such as Figure 1 、 2As shown in Figures 3, 4, and 5, the furnace body 1 comprises a furnace body 1, the front side of which is open and a sealing door 2 is slidably installed, a dovetail slider 3 is fixedly installed on the sealing door 2, a dovetail slide 4 is provided on the furnace body 1 corresponding to the dovetail slider 3, the dovetail slider 3 is slidably installed in the dovetail slide 4, the furnace body 1 is provided with a driving mechanism for driving the sealing door 2 to slide left and right, a grille plate 7 is provided in the furnace body 1, a smoke exhaust pipe 8 is connected and installed on the side wall of the furnace body 1, and a plurality of burners 5 are respectively provided on the upper, lower, left, and right sides of the inner wall of the furnace body 1. In this embodiment, three burners 5 are respectively provided on the upper, lower, left, and right sides of the inner wall of the furnace body 1, one end of each of the burners 5 extends out of the furnace body 1 and is connected and installed on the same gas pipe 6, and the gas pipe 6 is fixedly installed on the outside of the furnace body 1. The utility model has a simple structure and an ingenious design. The upper, lower, left, and right sides of the inner wall of the furnace body 1 are provided with a plurality of burners 5, which can heat multiple surfaces of the forging, have a good heating effect, can meet market demand, and is suitable for promotion. When using the utility model, the sealing door 2 is driven to move to the left by the driving mechanism, and the dovetail slider 3 slides in the dovetail slide groove 4 until the sealing door 2 no longer blocks the opening on the front side of the furnace body 1, and the workpiece to be forged is placed on the grid plate 7, and then the sealing door 2 is driven by the driving mechanism to seal the opening on the front side of the furnace body 1, and gas is introduced into the gas pipe 6. The gas is transported to the stove head 5 to burn and heat the workpiece to be forged, and the generated smoke is discharged from the furnace body 1 through the exhaust pipe 8. After the heating is completed, the gas is stopped from being introduced into the gas pipe 6, and the sealing door 2 is driven to open by the driving mechanism, and the workpiece to be forged can be taken out of the furnace body 1.

[0018] Specifically, as shown in the figure, the bottom of the grille plate 7 described in this embodiment is rotatably installed with several rollers 21 through the support legs 20, the tops of the support legs 20 are respectively fixedly connected to the bottom of the grille plate 7, and the bottoms of the support legs 20 are respectively rotatably installed with rollers 21. The rollers 21 are made of high-temperature resistant metal. Several grooves 22 are opened at the bottom of the inner wall of the furnace body 1 corresponding to the rollers 21. The front and upper sides of the grooves 22 are connected to the outside world. The rollers 21 roll in the corresponding grooves 22. The front side of the lower side wall of the furnace body 1 is provided with an inclined surface with a higher rear side and a lower front side. The rear side of the sealing door 2 is fixedly installed with a right-angled triangular sealing block 23 corresponding to the inclined surface. The inclined surface of the triangular sealing block 23 can be fitted with the inclined surface of the lower side wall of the furnace body 1. A triangular through groove 24 is opened on the side wall of the furnace body 1 corresponding to the triangular sealing block 23. The through groove 24 is opened on the left side wall of the furnace body 1, and the triangular sealing block 23 can slide out through the through groove 24. When the grille plate 7 is to be moved out of the furnace body 1, the sealing door 2 is driven to slide to the left by the driving mechanism, the dovetail slider 3 slides in the dovetail slide groove 4, and the sealing block 23 slides in the through groove 24 until the sealing door 2 does not hinder the grille plate 7 from being moved out. Then the supporting leg 20 is pulled forward, and the supporting leg 20 drives the grille plate 7 to move forward. The roller 21 moves forward in the corresponding groove 22, and the inclined surface facilitates the roller 21 to move smoothly to the ground.

[0019] Specifically, as shown in the figure, the bottom of the inner wall of the groove 22 in this embodiment is provided with a plurality of arcuate grooves 30 corresponding to the roller 21. The outer periphery of the roller 21 fits in contact with the inner periphery of the corresponding arcuate grooves 30. The arcuate grooves 30 can be used to position the roller 21, and thus the grid plate 7. At the same time, the arcuate grooves 30 can also prevent the roller 21 from moving freely.

[0020] Furthermore, as shown in the figure, the drive mechanism of this embodiment includes a motor 40, which is fixedly mounted on the furnace body 1 via a first connecting rod. A coaxial screw 41 is fixedly mounted on the output shaft of the motor 40. The screw 41 is rotatably mounted on the furnace body 1 via a bearing seat. The outer periphery of the screw 41 at one end away from the motor 40 is rotatably connected to the inner periphery of the bearing seat. The outer periphery of the bearing seat is fixedly mounted on the furnace body 1. The outer periphery of the screw 41 is threadedly mounted with a coaxial nut 42. The nut 42 is connected to the sealing door 2 via a second connecting rod. When the motor 40 is started, the output shaft of the motor 40 rotates, driving the screw 41 to rotate. The rotation of the screw 41 causes the nut 42 to move left and right along the screw 41. The screw 41 drives the sealing door 2 to move left and right via the second connecting rod.

[0021] Furthermore, as shown in the figure, the grille plate 7 of this embodiment includes a first U-shaped plate 50, the opening of the first U-shaped plate 50 facing the front side, a placement plate 51 slidably mounted within the first U-shaped plate 50, sliders 52 fixedly mounted on the left and right sides of the placement plate 51, and slots 53 corresponding to the sliders 52 are provided on the inner wall of the first U-shaped plate 50. The front sides of the slots 53 are respectively communicated with the outside world. The sliders 52 are slidably mounted within the corresponding slots 53. The top of the placement plate 51 is flush with the top of the first U-shaped plate 50, and the placement plate 51 is provided with a plurality of mesh holes 54. When the placement plate 51 is pulled forward, the placement plate 51 moves forward, driving the sliders 52 to slide forward along the corresponding slots 53 until the sliders 52 slide out of the corresponding slots 53. The placement plate 51 can then be removed from the first U-shaped plate 50, making it easy to replace a new placement plate 51 if it is damaged.

[0022] Furthermore, as shown in the figure, the first handle 60 is fixedly mounted on the front side of the placement plate 51 in this embodiment, and the same second handle 61 is fixedly mounted on the front support legs 20. Pulling the placement plate 51 with the first handle 60 is more convenient and labor-saving; pulling the support legs 20 with the second handle 61 is even more convenient and labor-saving.

[0023] Furthermore, as shown in the figure, a second U-shaped plate 70 is fixedly installed below the grid plate 7 in this embodiment. The opening of the second U-shaped plate 70 faces downward and is fixedly installed at the bottom of the inner wall of the furnace body 1. The lower burners 5 are located below the second U-shaped plate 70. The second U-shaped plate 70 is provided with a plurality of ventilation holes 71. The workpiece to be forged can be directly placed on the second U-shaped plate 70 for heating. When using it, the staff can choose according to actual needs.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
