Description

Technical Field

[0001] This utility model relates to the field of flame cutting machine technology, specifically an automatic cutting machine for continuous casting billets in steel plants. Background Technology

[0002] In the continuous casting process of steel production, the billet emerges from the crystallizer continuously. Flame cutting, as the final step in the continuous casting process, requires a flame cutting machine to cut the billet into the required length for easy transportation.

[0003] The patent publication number CN220718040U discloses a CNC flame cutting machine, which includes a conveying mechanism for conveying a sheet material and a cutting mechanism for cutting the sheet material. The cutting mechanism is fixed on the conveying mechanism. The machine also includes a housing with an inlet and an outlet at both ends. The housing is connected to the conveying mechanism, and the cutting mechanism is located inside the housing.

[0004] As shown in the above technology, the steel billets produced in the continuous casting billet production process of steelmaking plants are generally cut by flame cutting machines. At present, the continuous casting billets commonly produced in the steelmaking continuous casting industry are divided into four categories: small square (round) billets, large square (round) billets, rectangular billets, and irregular billets. Due to the limited production capacity of the continuous casting machine and the limited flame cutting capability, the flame gun cannot move well according to the different sizes of steel billets, especially when dealing with large steel billets, it cannot cut them well, resulting in poor cut quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic cutting machine for continuous casting billets in steel plants, which solves the problem that existing automatic cutting machines for continuous casting billets in steel plants cannot perform large-size cutting well.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic cutting machine for continuous casting billets in a steel plant includes an outer protective box and a flame gun. The left and right sides of the outer protective box are rotatably connected with two front and rear first rollers. The back of the outer protective box is provided with a clamping mechanism for clamping the steel billet. The inside of the outer protective box is provided with a cutting gun traveling mechanism.

[0007] The flame gun is mounted on the cutting torch traveling mechanism, which can drive the flame gun to move along different arc-shaped trajectories. The cutting torch traveling mechanism includes a lateral moving component and a longitudinal moving component, which are installed inside the outer protective box. The longitudinal moving component is mounted on the lateral moving component. The lateral moving component and the longitudinal moving component work to drive the flame gun to move simultaneously in the lateral and longitudinal directions.

The movable frame is slidably connected to the upper and lower roller rails through the four grooves. The back of the movable frame is fixedly connected to a first servo drive component, and the output end of the first servo drive component is fixedly connected to a drive gear. The drive gear meshes with a rack for transmission.

[0009] Preferably, the longitudinal movement component includes a frame, which is fixedly connected to a moving frame. A second servo drive is fixedly connected to the top of the frame, and a ball screw is fixedly connected to the output end of the second servo drive.

[0013] Beneficial effects

[0014] This utility model provides an automatic cutting machine for continuously cast billets in steel plants. Compared with the prior art, it has the following advantages:

[0015] 1. The automatic cutting machine for continuous casting billets in this steel plant uses a flame gun mounted on a cutting torch traveling mechanism. This mechanism drives the flame gun to move along different arc-shaped trajectories. The traveling mechanism includes a horizontal moving component and a vertical moving component. When cutting billets of different sizes, the flame gun is driven to move by the traveling mechanism, maintaining a fixed distance between the flame gun and the billet and moving along an arc-shaped trajectory. This ensures the smoothness and accuracy of the flame gun's movement. The special design of the flame gun allows for better cutting, especially when dealing with large billets, ensuring the quality of the cut and improving the practicality of the equipment.

The outer casing is fixedly connected to the bottom of the outer protective box. The bottom of the outer casing is V-shaped to allow the heat generated by flame cutting to diffuse more quickly. A fireproof sleeve is installed below the outer protective box. The V-shaped design at the bottom of the fireproof sleeve's outer casing is conducive to temperature diffusion, and the flow of cooling water can carry away the heat more quickly, thereby insulating the outer protective box and protecting the components inside the outer protective box.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-9 The steel plant's automatic billet cutting machine offers two technical solutions:

[0029] The first embodiment includes an outer protective box 1 and a flame gun 3. The left and right sides of the outer protective box 1 are rotatably connected with two front and rear first rollers 2. The back of the outer protective box 1 is provided with a clamping mechanism 7 for clamping the steel billet. The inside of the outer protective box 1 is provided with a cutting torch traveling mechanism.

[0030] The flame gun 3 is mounted on the cutting torch traveling mechanism, which drives the flame gun 3 to move along different arc-shaped trajectories. The flame gun 3 is connected to an external gas supply system. The diameter of the flame gun is specially designed and enlarged. The gas-air mixing ratio is finely adjusted by the gas system, allowing the flame emitted by the flame gun 3 to cut more quickly. The cutting torch traveling mechanism includes a lateral moving component 4 and a longitudinal moving component 5, which are installed inside the outer protective housing 1. The longitudinal moving component 5 is mounted on the lateral moving component 4. The lateral moving component 4 and the longitudinal moving component 5 work together to drive the flame gun 3 to move simultaneously in both the lateral and longitudinal directions. The lateral moving component 4... The system includes a transverse track 41 and a movable frame 42. The transverse track 41 is fixed inside the outer protective box 1. Roller rails 43 are provided at the top and bottom of the transverse track 41. A groove 44 is provided in the middle part of the transverse track 41, and a rack 45 is fixedly connected to the top of the inner wall of the groove 44. The front of the movable frame 42 has two sets of grooves 44, one above the other, and each set of grooves 44 consists of two grooves 44 on the left and one on the right. The movable frame 42 is slidably connected to the upper and lower roller rails 43 through the four grooves 44. A first servo drive component 46 is fixedly connected to the back of the movable frame 42. A drive gear 47 is fixedly connected to the output end of the first servo drive component 46. The drive gear 47 meshes with the rack 45 for transmission.

[0031] The longitudinal moving component 5 includes a frame 51, which is fixedly connected to the moving frame 42. A second servo drive 52 is fixedly connected to the top of the frame 51. A ball screw 53 is fixedly connected to the output end of the second servo drive 52. Two moving blocks 54 are connected to the surface of the ball screw 53. A connecting frame 55 is fixedly connected to the front of the two moving blocks 54. The flame gun 3 is fixedly connected to the connecting frame 55 by a clamp.

[0032] When cutting steel billets of different sizes, the flame gun 3 is driven to move by the cutting torch traveling mechanism, so that the flame gun 3 maintains a fixed distance from the steel billet and moves along an arc trajectory, ensuring the smoothness and accuracy of the flame gun's movement. The special design of the flame gun enables better cutting, especially when dealing with large steel billets. It can cut steel billets with a maximum circle size of 1320mm while still ensuring the quality of the cut, thus improving the practicality of the device.

[0033] The second embodiment differs from the first embodiment in that: the fireproof sleeve 6 includes an outer casing 61, which is fixedly connected to the bottom of the outer protective box 1. The bottom of the outer casing 61 is V-shaped to allow the heat generated by the flame cutting to diffuse more quickly. The front and back of the outer casing 61 are respectively provided with a water inlet 63 and a water outlet 64. The flame gun 3 and the lateral moving component 4 are connected to the cooling system through pipes. The bottom of the inner wall of the outer casing 61 is provided with a serpentine water channel 62, and the inlet and outlet of the water outlet 64 are connected to the water inlet 63 and the water outlet 64, respectively.

[0034] A fireproof sleeve 6 is installed below the outer protective box 1. The bottom of the outer box of the fireproof sleeve 6 is designed in a V-shape, which is conducive to the diffusion of temperature. The cooling water can carry away the temperature more quickly, thereby insulating the outer protective box 1 and protecting the internal components of the outer protective box.

[0035] In use, the steel billet is moved by the drive mechanism on the production line. When it enters the area below the cutting machine, the clamping mechanism 7 is activated to clamp the steel billet. After clamping, the cutting machine moves with the steel billet. At the same time, the cutting torch traveling mechanism is activated to drive the flame torch 3 to move, thereby cutting the steel billet. When the lateral moving component 4 is activated, the first servo drive 46 works and drives the drive gear 47 to rotate. The drive gear 47 rotates and cooperates with the rack 45 to move the moving frame 42, thereby driving the flame torch 3 to move laterally. At the same time, the second servo drive 52 is activated to make the ball screw 53 rotate. The rotation of the ball screw 53 drives the connecting frame 55 to move up or down through the moving block 54, thereby driving the flame torch 3 to move longitudinally. In addition, the heat generated during cutting is transferred to the bottom of the outer casing 61. The heat is diffused to both sides through the V-shaped structure and carried away by the cooling water flowing in the water channel 62.
