When the pressure reaches a certain value, the pressure sensor sends a signal. At this time, driving mechanism 2 drives chuck 1 and chuck 2 to rotate simultaneously, thereby driving the rim to rotate. After 2-3s, the time relay sends a signal, and the knurling wheel moves downward and contacts the rim.

At this time, the knurling wheel knurls the rim on both sides of the rim at the same time, and the production efficiency is high.

[0010] In the above-mentioned rim knurling device, a guide rail is installed on the base, a slider is installed at the bottom of the mounting seat 2, the slider is slidably connected to the guide rail, the driving mechanism 1 includes a hydraulic cylinder 1 or a cylinder, the hydraulic cylinder 1 or the cylinder is installed on the mounting seat 1 or the base, the piston rod of the hydraulic cylinder 1 is connected to the mounting seat 1 or the piston rod of the cylinder is connected to the base.
