[0008] In the preferred embodiment, the rolling roller is made of alloy steel.

[0009] Among them, the rolling rollers are divided into two types, one uses an external convex arc generatrix, which is responsible for rolling the grooves of the workpiece, and the other uses an internal concave angular generatrix, which is responsible for hardening the edges of the workpiece.

[0010] Preferably, 16 rolling assemblies are provided on each side of the stand, and the rolling assemblies on both sides are respectively responsible for the groove forming and edge hardening of the workpiece; the 16 rolling assemblies on each side are divided into 2 groups according to the intervals, and each group has 8 rolling assemblies. Two groups can work simultaneously for rolling 16-sided workpieces, or only one group can work for rolling 8-sided workpieces; pressure covers are provided on the outer sides of the rolling assemblies on both sides.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows:

[0012] 1. This scheme sets up a vertical machine base for the special rolling mechanism for cold rolling of plum blossom-shaped tubes and rods, which occupies a small space.

[0013] 2. This solution sets 16 groups of rolling components on both sides of the vertical machine base, arranged in a ring, with a compact structure and easy installation.

[0014] 3. This scheme sets up a rolling cylinder, a pressure cover, a roller pressure head, a roller, and a fixed shaft in the rolling assembly. Copper-based self-lubricating plates are provided on the four sides of the roller pressure head. The pressure cover and the seat guide groove form a closed guide.
