technical field [0001] The invention belongs to the technical field of metal rolling, and in particular relates to a cantilever type rolling device suitable for rolling processing of thin-walled cylindrical workpieces. Background technique [0002] At present, the roll forming of thin-walled cylindrical workpieces is mainly realized by traditional roller presses. Before the traditional roller presses perform roll forming of thin-walled cylindrical workpieces, the workpiece clamping operation usually needs to be completed manually, resulting in the clamping of the workpiece. The precision is not high, and in the process of workpiece roll forming, the workpiece always needs to be supported by workers manually, resulting in high labor intensity and low production efficiency.

[0002] At present, the roll forming of thin-walled cylindrical workpieces is mainly realized by traditional roller presses. Before the traditional roller presses perform roll forming of thin-walled cylindrical workpieces, the workpiece clamping operation usually needs to be completed manually, resulting in the clamping of the workpiece. The precision is not high, and during the roll forming process of the workpiece, the workpiece always needs to be supported by the workers manually, resulting in a high labor intensity for the workers and low production efficiency

[0003] Since the workpiece always bears a large force during the roll forming process, under manual support, if the support force is not enough, it is easy to cause uneven force on the workpiece, which will lead to deflection and misalignment of the workpiece, and will also cause damage to the workpiece. The personal safety of workers brings certain hidden dangers

In addition, due to the large vibration of the traditional roller press during operation, this directly increases the difficulty of manual support, and ultimately makes it difficult to guarantee the processing quality of the workpiece
