[0028] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] Embodiment 1

[0030] As Figure 1 and Figure 2 shown, Embodiment 1 of the present application provides a spinning mechanism 1. The spinning mechanism 1 is usually installed on the main shaft 2 of the flanging device and is driven to rotate by the main shaft 2. The driving principle of the spinning mechanism 1 can be referred to the detailed description in CN108213231A and CN221158203U with the publication number, and will not be repeated in this embodiment.

[0031] In this embodiment, the spinning mechanism 1 includes a turntable 11, a plurality of inclined wheel assemblies 12 and a limit block 13. Among them, the turntable 11 can rotate around an axis. The plurality of inclined wheel assemblies 12 are all arranged on the turntable 11, and all the inclined wheel assemblies 12 are arranged in a circumferentially uniform distribution centered on the axis. The inclined wheel assembly 12 includes an inclined wheel seat 122 and an inclined pressure wheel 121. The inclined pressure wheel 121 rotates on the inclined wheel seat 122, and the inclined wheel seat 122 is arranged on the turntable 11 and can be adjusted along the radial direction of the axis; the limit block 13 is arranged on the turntable 11, and the limit block 13 abuts against the inclined wheel seat 122 to block and limit the inclined wheel seat 122.

[0032] In the spinning mechanism 1 of this embodiment, by setting the cam assembly 12 to be adjustable and adjusting the distance between the cam assembly 12 and the center of the turntable 11, it is adapted to process workpieces of different diameters. By arranging a limiting block 13 on the turntable 11 to abut against the cam seat 122, it is prevented that the cam seat 122 moves on the turntable 11 during processing.

[0033] In this embodiment, at least one gasket 14 is also provided between the limiting block 13 and the cam seat 122. The gasket 14 is arranged in a detachable manner. The gasket 14 is used to adjust the distance between the limiting block 13 and the cam seat 122 by its thickness. The gasket 14 can have multiple thickness specifications. By adjusting the number of gaskets 14 and using gaskets 14 with different thicknesses, the distance between the limiting block 13 and the cam seat 122 is adjusted, so as to adjust the position of the cam seat 122 on the turntable 11. The adjustment of the gasket 14 is simple and convenient, and it can bear a greater acting force, which is stable and reliable.

[0034] In this embodiment, an internal screw hole 131 is provided on the limiting block 13. An adjustable plunger 15 is arranged in the internal screw hole 131. One end of the plunger 15 abuts against the gasket 14. A positioning hole is provided on the surface of the gasket 14 facing the plunger 15. The positioning hole is a non-conductive hole. A ball is provided at one end of the plunger 15. The ball has elasticity due to the spring inside the plunger 14. One end of the ball of the plunger 15 is inserted into the positioning hole of the gasket 14, and the other end is exposed outside the limiting block 13 for screwing. The ball gives an elastic acting force to the gasket 14. The plunger 15 prevents loosening and falling during work. When using multiple gaskets 14, a limiting structure can also be arranged between adjacent gaskets 14 to cooperate with each other. A better way is to configure multiple gaskets 14 with different thicknesses, and replace the gasket 14 with the corresponding thickness according to the distance to be adjusted.

[0035] In this embodiment, a convex portion 132 extending towards the cam seat 122 is provided at one end of the limiting block 13 away from the turntable 11. The gasket 14 is limited between the convex portion 132 and the turntable 11, and the convex portion 132 is used to limit the gasket 14.

[0036] In this embodiment, the cam seat 122 is provided with a waist-shaped hole 1221. A stud 16 passing through the waist-shaped hole 1221 is installed on the turntable 11. The stud 16 is used to fasten the cam seat 122. Exemplarily, the number of waist-shaped holes 1221 is two, and the length direction of the waist-shaped holes 1221 passes through the axis of the turntable 11.

[0037] When the cam seat 122 needs to be adjusted, first loosen the stud 16 to enable the cam seat 122 to move limitedly in the length direction of the waist-shaped hole 1221. After adding, reducing or replacing the gasket 14 between the cam seat 122 and the limiting block 13, press the cam seat 122 and the gasket 14 tightly, and fasten the stud 16 to fix the cam seat 122. The plunger 15 can also be screwed to press the gasket 14 tightly.

[0038] In this embodiment, the skew press wheel 121 is rotatably arranged on the skew wheel seat 122 through a rotating shaft 17 and bearings, and the rotation axis of the skew press wheel 121 is parallel to the axis of the turntable 11. A spinning surface is provided on the side surface of the skew press wheel 121, and the spinning surface includes a linear spinning section 1211 and an arc spinning section 1212 connected to the linear spinning section 1211.

[0039] In this embodiment, the spinning mechanism 1 further includes a plurality of flat wheel assemblies 19, and the flat wheel assemblies 19 are all arranged on the turntable 11, and all the flat wheel assemblies 19 are arranged in a circumferentially uniform distribution centered on the axis. For the specific structure of the flat wheel assembly 19, reference can be made to the detailed description in the patent with publication number CN108213231A and patent number CN221158203U, which belongs to the prior art and will not be described herein.
