[0025] See also Figure 3 as well as Figure 4During operation, a workpiece 8 (such as a chimney) is placed on a work surface 11, so that the circumferential surface of the first positioning component 2 abuts against the inner wall of the workpiece 8, and the flange 81 to be formed on the outer wall of the workpiece 8 is placed between the circumferential surface of the second positioning component 3 and the circumferential surface of the pressing component 4. Then, the second positioning component 3 and the pressing component 4 are driven to rotate by the rotary drive mechanism 5, so that the workpiece 8 can rotate relative to the work surface 11 under the friction force of the second positioning component 3 and the pressing component 4. The rotation of the workpiece 8 and the pressing component 4 generate the power required for tensile deformation. By utilizing the spinning flanging forming method, the workpiece 8 can be gradually tensilely deformed according to the shape of the second positioning component 3 and the pressing component 4 during its rotation, with uniform force and beautiful forming. While improving the processing quality, the processing efficiency is also greatly improved.

[0026] As a preferred embodiment, the first positioning component 2 is a bearing 64 or a rotating wheel with a rotatable outer ring, so that the friction resistance between the workpiece 8 and the first positioning component 2 can be reduced, so that the workpiece 8 can rotate smoothly, ensuring processing efficiency and processing quality.

[0032] See also Figure 3 As a preferred embodiment, the second driven rotating shaft 520 includes a first connecting shaft 5201, a universal coupling 5202 and a second connecting shaft 5203 which are connected in sequence, the first connecting shaft 5201 is connected to the second driven gear 510, and the second connecting shaft 5203 is connected to the pressing component 4. By using the universal coupling 5202 to connect the first connecting shaft 5201 and the second connecting shaft 5203, the pressing component 4 can be adjusted in up and down displacement without affecting the meshing between the second driven gear 510 and the first driven gear 58.

[0038] See also Figure 1 As a preferred embodiment, the flanging forming equipment also includes a second linear drive mechanism 7, which is used to drive the first positioning component 2 to approach or move away from the second positioning component 3 or the pressing component 4, so that the distance between the circumferential surface of the first positioning component 2 and the end surface of the second positioning component 3 or the end surface of the pressing component 4 is adjustable, so that the first positioning component 2 can be reciprocated relative to the second positioning component 3 or the pressing component 4, thereby driving the workpiece 8 to reciprocate. The gradual feeding amount of the first positioning component 2 generates the strain force required by the workpiece 8 during the stretching process. Therefore, the rotation of the workpiece 8 combined with the gradual feeding of the first positioning component 2 realizes the rotational pressing forming of the workpiece 8, and the gradual stretching deformation according to the shape of the second positioning component 3 and the pressing component 4 is realized during the rotation of the workpiece 8 and the gradual feeding of the first positioning component 2.

In this way, the second motor is used to drive the second slider 75 to slide, thereby driving the first positioning component 2 to move.

[0040] The working principle of a flanging forming device of the present invention is as follows:

[0041] During operation, a workpiece 8 (such as a chimney) is placed on a work surface 11, so that the circumferential surface of the first positioning component 2 abuts against the inner wall of the workpiece 8, and the flange 81 to be formed on the outer wall of the workpiece 8 is placed between the circumferential surface of the second positioning component 3 and the circumferential surface of the pressing component 4. Then, the second positioning component 3 and the pressing component 4 are driven to rotate by the rotary drive mechanism 5, so that the workpiece 8 can rotate relative to the work surface 11 under the friction of the second positioning component 3 and the pressing component 4. The rotation of the workpiece 8 and the rotation of the pressing component 4 generate the power required for tensile deformation, and the gradual feed amount of the first positioning component 2 generates the strain force required for the workpiece 8 during the stretching process. Therefore, the rotation of the workpiece 8 is combined with the gradual feeding of the first positioning component 2 to realize the rotational pressing molding of the workpiece 8. In the process of the rotation of the workpiece 8 and the gradual feeding of the first positioning component 2, progressive tensile deformation according to the shape of the second positioning component 3 and the pressing component 4 is realized, the force is even, the forming is beautiful, and while the processing quality is improved, the processing efficiency is also greatly improved.
