The above technical solution solves the problem that the existing bending machine cannot meet the bending requirements of steel plates of various specifications. The utility model provides a bending machine suitable for bending steel plates of various specifications and sizes. However, in actual use, there are still many defects in arc bending machines with similar structures. For example, during the use process, the bending degree cannot be effectively adjusted, so the specifications are limited during the manufacturing process, which affects the production efficiency. Therefore, it is necessary to design a rod-shaped metal arc bending machine to solve the problems raised in the above background technique. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rod-shaped metal arc bending machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rod-shaped metal arc bending machine, including a mounting base, a mounting sleeve and a lower pressing plate. A support column is fixedly installed at the bottom of the mounting base. A mounting sleeve is fixedly installed at the top of the mounting base.

A connecting sleeve is threadedly installed inside the lower pressing plate through a fixed sleeve. An extrusion tube is fixedly installed on one side of the connecting sleeve. Through the rotational action at the output end of the motor, the transmission belt synchronously drives the limiting roller, so that the metal rod on the limiting roller can be transmitted. At the same time, by rotating the threaded rod, the threaded rod slides along the inside of the threaded sleeve, so that the extrusion tube can extrude the metal rod, thereby performing an arc bending operation on the metal rod between the extrusion tube and the limiting roller.

[0008] Preferably, a limiting rod is fixedly installed at the top of the mounting seat, and movable grooves cooperating with the limiting rod are formed on both sides of the lower pressing plate. The sliding between the movable groove and the limiting rod can make the movement between the mounting sleeve and the lower pressing plate more stable, enhancing the stability effect.

[0009] Preferably, a threaded rod is rotatably installed at the top of the mounting sleeve through a bearing sleeve, a threaded sleeve is fixedly installed at the rear end of the lower pressing plate, and the threaded rod and the threaded sleeve are in threaded cooperation. By rotating the threaded rod, the threaded rod slides along the inside of the threaded sleeve, enabling the extrusion tube to extrude the metal rod, and thus performing an arc-bending operation on the metal rod between the extrusion tube and the limiting roller.

[0010] Preferably, a motor is fixedly installed inside the limiting roller, and the motor and the limiting roller are installed through a transmission belt. The rotation of the output end of the motor synchronously drives the transmission belt to drive the limiting roller, enabling the metal rod on the limiting roller to be transported.

[0011] In summary, the present application includes the following beneficial technical effects:

[0012] 1. In the present utility model, the rotation of the output end of the motor synchronously drives the transmission belt to drive the limiting roller, enabling the metal rod on the limiting roller to be transported.

Meanwhile, adjusting the position of the extrusion tube can perform a bending operation on metal rods of different specifications.

[0022] The working principle of a rod-shaped metal bending machine based on Embodiment 1 is as follows: The rotation at the output end of the motor 201 synchronously drives the transmission belt 202 to drive the limiting roller 203, enabling the metal rod on the limiting roller 203 to be transmitted. At the same time, by rotating the threaded rod 303, the threaded rod 303 slides along the inside of the threaded sleeve 304, enabling the extrusion tube 308 to extrude the metal rod. Thus, an arc-bending operation is performed on the metal rod between the extrusion tube 308 and the limiting roller 203. Meanwhile, adjusting the position of the extrusion tube 308 can perform a bending operation on metal rods of different specifications. By driving the fine-tuning plate 305, the connecting sleeve 307 can move up and down, enabling the extrusion tube 308 to perform fine-tuning operations for different specifications during the extrusion of the metal rod. The spring 309 can extrude the connecting sleeve 307, and it can be extruded during the recovery process of the extrusion tube 308, making the adjustment process more convenient.

Activity slots 301 cooperating with the limiting rod 302 are provided on both sides of the lower pressing plate 3. The top of the mounting sleeve 2 is rotatably installed with a threaded rod 303 through a bearing sleeve. The rear end of the lower pressing plate 3 is fixedly installed with a threaded sleeve 304. The threaded rod 303 is in threaded cooperation with the threaded sleeve 304. A motor 201 is fixedly installed inside the limiting roller 203, and the motor 201 and the limiting roller 203 are drivingly installed through a transmission belt 202.

[0025] In this embodiment, as Figure 2 shown, sliding between the activity slot 301 and the limiting rod 302 can make the movement between the mounting sleeve 2 and the lower pressing plate 3 more stable during the movement, enhancing the stability effect; as Figure 4 shown, by rotating the threaded rod 303, the threaded rod 303 slides along the inside of the threaded sleeve 304, enabling the extrusion tube 308 to extrude the metal rod. Thus, an arc-bending operation is performed on the metal rod between the extrusion tube 308 and the limiting roller 203; as Figure 3 shown, the rotation at the output end of the motor 201 synchronously drives the transmission belt 202 to drive the limiting roller 203, enabling the metal rod on the limiting roller 203 to be transmitted.
