[0002] A head, also known as an end cap, is used to seal the end of a container, isolating the internal and external media. The head of a cylindrical container is typically a rotating shell. Currently, conical heads are mostly formed by stamping the main body using a press and then welding. However, due to the presence of seams in welding, they are not as strong as heads formed in one piece. Therefore, a spinning machine is needed to spin conical heads.

[0003] For example, the announcement number "CN217912371U" describes a high-strength conical head forming device. This device uses a spinning machine to spin the conical head. The conical head is formed integrally through internal and external spinning devices, resulting in high strength and the ability to clamp and secure heads of different sizes. However, this device lacks support for the head during spinning. The force generated by the head's rotation during spinning can cause the head to deflect, resulting in deformation and poor quality of the head. Utility Model Content

[0033] Working principle:

[0034] When the conical head 17 needs to be spun, the angle of the support rod 408 in the support structure 4 needs to be adjusted first.

[0035] Angle adjustment of support rod 408:

[0036] Connect the external power supply of the second motor 402, start the second motor 402 to drive the third threaded rod 403 to rotate, the rotation of the third threaded rod 403 drives the third threaded block 405 to move, the movement of the third threaded block 405 drives the first straight rod 406 to move, the movement of the first straight rod 406 drives the second straight rod 407 to move, the movement of the second straight rod 407 drives the support rod 408 to move, the movement of the support rod 408 drives the universal ball 409 to move, and the angle of the support rod 408 is adjusted according to the size of the conical head 17 to be spun to complete the angle adjustment of the support rod 408.

[0037] After the angle adjustment is completed, the conical head 17 is placed above the base plate 6, and then the second hydraulic cylinder 12 is started to drive the mounting block 13 to move downward. The downward movement of the mounting block 13 drives the rotating block 14 to move downward, so that the rotating block 14 and the base plate 6 are tightly pressed against the conical head 17 to complete the pressing of the conical head. Then, the first hydraulic cylinder 5 and the second hydraulic cylinder 12 are started at the same time, and the output ends of the first hydraulic cylinder 5 and the second hydraulic cylinder 12 move at the same time to adjust the height of the conical head 17 to facilitate the processing of the conical head 17. The height of the conical head 17 can also be continuously adjusted while the conical head 17 is being processed.

[0038] Height adjustment of the support structure 4:

[0039] Connect the external power supply of the double-headed motor 302, start the double-headed motor 302 to drive the second threaded rod 303 to rotate, the rotation of the second threaded rod 303 drives the second threaded block 304 to move, the movement of the second threaded block 304 drives the connecting rod 305 to move, and setting two groups of connecting rods 305 can increase the stroke of the first block 306 to twice that of one group of connecting rods 305. The upper connecting rod 305 moves to drive the first block 306 to move, the movement of the first block 306 drives the second block 307 to move, the movement of the second block 307 drives the vertical rod 308 to move, the movement of the vertical rod 308 drives the cross rod 309 to move, and the movement of the cross rod 309 drives the support structure 4 to move, so that the universal ball 309 fits against the outer wall of the conical head 17, and can maintain support for the conical head 17 while the conical head 17 moves.

[0040] The conical head is then transported between the internal spinning device 15 and the external spinning device 16. The working mode of the internal spinning device 15 and the external spinning device 16 is the same as that in the announcement number "CN217912371U". The internal spinning device 15 and the external spinning device 16 are started to spin the conical head at the same time. After the spinning is completed, the fixed assembly is reset according to the reverse operation of the above steps, and the processed conical head is taken out.
