Description

Technical Field

[0001] This utility model relates to the field of steel manufacturing technology, specifically to a steel turning machine for I-beam billet rolling mills. Background Technology

[0002] Roughing mills, due to rolling process requirements, perform flipping rolling on steel billets. During rolling, the billets need to be flipped 90° or 180° to meet product quality requirements. Billet flipping machines are widely used automated equipment in the steel industry, mainly for flipping and positioning steel billets during steelmaking. This equipment features a compact structure, simple operation, and high stability, making it an important tool for improving production efficiency, reducing labor intensity, and ensuring production safety in steel enterprises. It involves flipping the steel during rolling, ensuring that both sides are subjected to rolling forces alternately. This process is widely used in the steel industry, especially in the production of hot-rolled steel plates and coils. The core purpose of the flipping rolling process is to ensure balanced quality and performance on both sides of the steel, improving the overall product quality.

[0003] Existing head-cutting methods include: 1. Hydraulic tilting machine: This type uses one or more hydraulic cylinders to drive an actuator, which in turn flips the workpiece. It has high environmental requirements and is not suitable for high-temperature environments. 2. Mechanical rotary tilting machine: This type uses a mechanical clamping mechanism to hold the workpiece, which is then mechanically driven to rotate around a rotating body, thus flipping the workpiece. This type of tilting mechanism is large, complex, and inefficient, making it unsuitable for large-scale production lines. Utility Model Content

[0004] The purpose of this utility model is to provide a steel turning machine for I-beam billet rolling mills to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel turning machine for an I-beam billet rolling mill, comprising a support platform, and further comprising: A flipping assembly for flipping steel billets is installed on a support platform. The flipping assembly has a high-temperature steel billet mounted on it and a transmission assembly that drives the flipping assembly to work. A power assembly that drives the transmission assembly to work is also installed on the support platform.

[0006] Preferably, the power assembly includes a speed reducer mounted on a support platform, and a drive motor is mounted on the speed reducer.

[0007] Preferably, the transmission assembly includes a drive link fixedly mounted on the output shaft of the reducer, a transition link rotatably mounted on the other end of the drive link, and a drive link rotatably mounted on the other end of the transition link.

[0008] Preferably, the flipping assembly includes a drive shaft rotatably mounted on the top of the support platform, the drive shaft being fixedly connected to the active connecting rod, and two symmetrical actuating connecting rods being fixedly mounted on the drive shaft, with a billet pawl rotatably mounted on the other end of each actuating connecting rod.

[0009] Preferably, a bearing seat is fixedly installed on the top of the support platform, and the drive shaft is rotatably installed inside the bearing seat.

[0010] Preferably, a support base plate is fixedly installed on one side of the support platform, and the reducer and drive motor are both fixedly installed on the top of the support base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model features a separate and independent drive and actuator mechanism, preventing the motor from contacting high-temperature areas. It cleverly utilizes the principle of linkage transmission, allowing torque to be transmitted between the linkages, thus expanding the load-bearing capacity range. The motor's rotary motion is free of jamming points, resulting in high efficiency. The mechanism is simple, impact-resistant, and has a long service life. The motor directly outputs power, and the linkage directly transmits torque, minimizing energy loss. Due to its simple structure, maintenance is convenient, and it has a large load-bearing capacity, making it suitable for various types of steel. Because of its simple mechanism, production line modifications and installations are easy to implement, requiring minimal alteration to existing equipment. The cost is low.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structure, features and effects of this utility model.

[0015] Please see Figure 1-4As shown, a billet turning machine for an I-beam rolling mill includes a support platform 1 and a turning assembly 4 installed on the support platform 1 for turning billets. A high-temperature billet 5 is installed on the turning assembly 4, and a transmission assembly 3 is installed on the turning assembly 4 to drive the turning assembly 4. A power assembly 2 is also installed on the support platform 1 to drive the transmission assembly 3.

[0016] When the billet is heated to the appropriate temperature in the heating furnace, it is transported to the front of the roughing mill by the conveyor roller. The power component 2 controls the operation of the transmission component 3, which in turn drives the flipping component 4 to flip the high-temperature steel billet 5.

[0017] like Figure 2 and Figure 3 As shown, the power assembly 2 includes a reducer 21 mounted on a support platform 1, and a drive motor 22 mounted on the reducer 21; a support base plate 7 is fixedly mounted on one side of the support platform 1, and the reducer 21 and the drive motor 22 are both fixedly mounted on the top of the support base plate 7; the output end of the drive motor 22 and the output end of the reducer 21 are fixedly connected by a coupling.

[0018] During operation, the output end of the reducer 21 is driven to rotate by the drive motor 22.

[0019] As shown in the figure, the transmission assembly 3 includes a drive link 31 fixedly mounted on the output shaft of the reducer 21, a transition link 32 rotatably mounted on the other end of the drive link 31, and a drive link 33 rotatably mounted on the other end of the transition link 32; the tilting assembly 4 includes a transmission shaft 41 rotatably mounted on the top of the support platform 1, the transmission shaft 41 being fixedly connected to the drive link 33, and two symmetrical actuation links 42 being fixedly mounted on the transmission shaft 41, with a billet pawl 43 rotatably mounted on the other end of the actuation link 42; one end of the drive link 31 is fixedly connected to the output end of the reducer 21, and the other end is rotatably connected to one end of the transition link 32, the other end of the transition link 32 is rotatably connected to the drive link 33, the other end of the drive link 33 is fixedly mounted in the middle of the transmission shaft 41, one end of the actuation link 42 is fixedly mounted on the transmission shaft 41, and the other end is rotatably connected to the upper part of the billet pawl 43.

[0020] When the billet is heated to a suitable temperature in the heating furnace, it is transported to the front of the roughing mill by the conveyor rollers. The billet claw 43 is located below the transmission rollers. When the billet is transported to the top of the billet claw 43, the operator in the control room gives the instruction to flip the billet. The drive motor 22 runs, causing the drive linkage 31 to start rotating around the output shaft of the reducer 21. When the drive linkage 31 moves to the horizontal position, it drives the transition linkage 32 to move accordingly, which in turn pushes the active linkage 33 to move. The active linkage 33 and the execution linkage 42 are fixed on the transmission shaft 41, causing the execution linkage 42 to move upward and lift the billet claw 43 upward. Since the billet claw 43 is in contact with the bottom part of the high-temperature billet 5, the high-temperature billet 5 loses its balance during the movement, thereby achieving the purpose of flipping the high-temperature billet 5.

[0021] As shown in the figure, a bearing seat 6 is fixedly installed on the top of the support platform 1, and the drive shaft 41 is rotatably installed inside the bearing seat 6; four sets of bearing seats 6 are fixedly installed on the top of the support platform 1, and the drive shaft 41 is rotatably installed inside the bearing seat 6.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
