[0033] The technical scheme of the present application will be described in detail below with specific examples. The following specific examples can be combined or replaced according to actual conditions, and the same or similar concepts or processes may not be described in some examples.

[0034] As shown in Figure 1 and Figure 2 The present application provides a flanging device of an automatic round rolling and shaping flanging forming machine, which is installed on the body of the automatic round rolling and shaping flanging forming machine. The flanging device comprises a linear motor 10, a guide column 20 and a flanging die 30. The linear motor 10 is fixed on the body, the guide column 20 is slidingly installed on the body, and the flanging die 30 is installed on the guide column 20. The axis direction of the output shaft of the linear motor 10 is different from the axis direction of the guide column 20. The linear motor 10 is drivingly connected to the guide column 20 through a reversing assembly to drive the guide column 20 to slide.

[0035] The linear motor 10 is drivingly connected to the guide column 20 through the reversing assembly, which changes the direction of the output force of the linear motor 10 to drive the guide column 20 to slide. The linear motor 10 can be installed at different positions of the body, avoiding the requirement that the motor and the guide column 20 must be arranged along the same axis in the traditional design. The non-coaxial design allows the overall structure of the flanging device to be more compact, reducing the length in a particular direction, and is more suitable for installation in limited space.

[0036] In this embodiment, the axis direction of the output shaft of the linear motor 10 is perpendicular to the axis direction of the guide column 20, reducing the length in a particular direction. The linear motor 10 and the reversing assembly are located on the same side of the body, and the linear motor 10 and the flanging die 30 are located on different sides of the body, and do not interfere with each other.

This enhances the stability and reliability of the entire system, reduces the motion deviation caused by the instability of the motor, and ensures the accuracy of the operation of the flanging die 30.

[0038] The reversing assembly includes a first connecting rod 40, a second connecting rod 41 and a third connecting rod 42, one end of the first connecting rod 40 is fixedly connected with the output shaft of the linear motor 10, the second connecting rod 41 and the third connecting rod 42 are respectively located on both sides of the axis of the first connecting rod 40, one end of the second connecting rod 41 and one end of the third connecting rod 42 are hingedly connected with the other end of the first connecting rod 40, the other end of the second connecting rod 41 is hingedly connected with the guide column 20, and the other end of the third connecting rod 42 is hingedly connected with the machine body. The extension and retraction movement of the output shaft of the linear motor 10 drives the second connecting rod 41 and the third connecting rod 42 to rotate through the first connecting rod 40, so as to drive the guide column 20 to slide. Through the hinged connection, the connecting rod structure can effectively change the direction of the force, allow the linear motor 10 to be installed at a position not directly along the axis of the guide column 20, make the entire flanging device more compact, reduce the length of the flanging device in a certain direction, and allow the linear motor 10 to be flexibly arranged according to actual needs without being limited by the movement path of the guide column 20.

[0039] In order to further make the structure more compact, the extension direction of the output shaft of the linear motor 10 is parallel to the plane in which the two guide columns 20 are located, and the parallel arrangement makes the entire flanging device more flattened and the structure more compact.

[0040] In order to improve the stability of the flanging die 30, the guide column 20 is provided with two, two connecting plates 21 are arranged between the two guide columns 20, the two connecting plates 21 are respectively located at the two ends of the guide column 20 and are fixedly connected with the two guide columns 20, the flanging die 30 is installed on one of the connecting plates 21, and the other end of the second connecting rod 41 is hingedly connected with the other connecting plate 21. By arranging the two guide columns 20 and the two connecting plates 21, the entire flanging device obtains better mechanical support, reduces the bending or deformation of a single guide column 20, and helps the stability and accuracy of the flanging die 30 in the entire working stroke.

This helps to keep the position of the flanging die 30 in the working stroke within a predetermined range as much as possible, avoiding mechanical damage or operation errors caused by excessive stretching or contraction of the output shaft of the linear motor 10.

[0045] Further, the connecting plate 21 is provided with a limiting slot 22 for limiting the rotation angle of the second connecting rod 41, and the other end of the second connecting rod 41 is hinged in the limiting slot 22. The limiting slot 22 can accurately limit the rotation angle of the second connecting rod 41, limiting its movement within a predetermined range, thereby effectively limiting the excessive swing of the second connecting rod 41 to make the movement path of the guide post 20 and the flanging die 30 in each flanging operation more consistent, and to ensure the consistency and quality of each workpiece as much as possible.

[0046] In order to facilitate the assembly of the third connecting rod 42, a hinged seat 44 is further provided, which is fixed on the machine body, and the other end of the third connecting rod 42 is hinged with the hinged seat 44.
