[0029] Square tube workpiece 2 placed on top of platform 1;

[0030] The top of platform 1 is provided with a fixed structure 3 located on one side of the square tube workpiece 2. The top of platform 1 is provided with a bending structure 4 located on one side of the fixed structure 3. The top of square tube workpiece 2 is provided with a transmission structure for driving the fixed structure 3 and the bending structure 4 to move continuously. The transmission structure includes gears 5 fixedly connected to the surfaces of the bending structure 4 and the fixed structure 3. The top of platform 1 is fixedly connected with a connecting frame 6. The inside of the connecting frame 6 is movably connected to a lead screw 7 through a bearing. The surface of the lead screw 7 is threadedly connected with a toothed plate 8. The toothed plate 8 can mesh with two gears 5 in sequence.

[0031] refer to Figure 1 The fixed structure 3 includes a screw 9 movably connected to the top of the platform 1 via a bearing. A pressure plate 10 is threaded onto the surface of the screw 9. The side of the pressure plate 10 away from the screw 9 extends to the top of the square tube workpiece 2. A gear 5 is fixedly connected to the surface of the screw 9 and located at the bottom of the pressure plate 10.

[0032] As a technical optimization of this utility model, by setting the screw 9 and the pressure plate 10, the square tube workpiece 2 can be stably fixed, preventing the square tube workpiece 2 from shifting during processing.

[0033] refer to Figure 1 The bending structure 4 includes a shaft 11 movably connected to the top of the platform 1 via a bearing, a rocker arm 12 fixedly connected to the surface of the shaft 11, a pressing wheel 13 fixedly connected to the side of the rocker arm 12 away from the shaft 11, and a gear 5 fixedly connected to the surface of the shaft 11 and located at the bottom of the rocker arm 12.

[0034] As a technical optimization of this utility model, by setting the shaft 11, the swing arm 12 and the extrusion wheel 13, the square tube workpiece 2 can be pushed to perform bending operation, thereby improving the bending stability of the square tube workpiece 2.

[0035] refer to Figure 4 A guide bar 14 is fixedly connected inside the connecting frame 6. The guide bar 14 extends into the toothed plate 8 from the side away from the connecting frame 6 and is slidably connected to the toothed plate 8.

[0036] As a technical optimization of this utility model, by setting the guide bar 14, the toothed plate 8 can be limited, thus preventing the toothed plate 8 from tilting during movement.

[0037] refer to Figure 4 A support plate 15 is fitted onto the top of the screw 9, and the left and right sides of the support plate 15 are fixedly connected to the top of the platform 1.

[0038] As a technical optimization of this utility model, by setting a support plate 15, the screw 9 can be supported, which can increase the contact area between the screw 9 and the platform 1.

[0040] As a technical optimization of this utility model, by setting the guide rod 16, the pressure plate 10 can be limited, so as to avoid the pressure plate 10 tilting during the movement.

[0041] The working principle and usage process of this utility model are as follows: In use, the square tube workpiece 2 is first placed on the top of the platform 1, and then the lead screw 7 is rotated. The lead screw 7 uses the thread to push the toothed plate 8 to move horizontally. When the toothed plate 8 contacts the gear 5 on the surface of the screw 9, the gear 5 can drive the screw 9 to rotate. The screw 9 uses the thread to push the pressure plate 10 to move downward. When the surface of the pressure plate 10 contacts the top of the square tube workpiece 2, the toothed plate 8 moves to the left side of the gear 5 on the surface of the screw 9 and continues to move horizontally. When the toothed plate 8 contacts the gear 5 on the surface of the shaft 11, the gear 5 can push the swing rod 12 to swing. The swing rod 12 uses the extrusion wheel 13 to extrude the square tube workpiece 2, thereby completing the continuous bending operation of the square tube workpiece 2.

[0042] In summary, this zinc-aluminum-magnesium square tube bending machine uses a lead screw 7 to drive the toothed plate 8 horizontally, so that the toothed plate 8 contacts the gears 5 on the surfaces of the fixed structure 3 and the bending structure 4 in sequence. This achieves continuous control of the fixed structure 3 and the bending structure 4, replacing the operation steps of controlling the two independently and improving the ease of operation.
