Feeding mechanism of numerical control arc rolling machine

The utility model relates to the technical field of machine tools, in particular to a feeding mechanism of a numerical control arc rolling machine, which comprises a support, the support is provided with an S-shaped channel for materials to roll downwards, the lower end of the S-shaped channel is provided with a material blocking assembly and a material guiding assembly, and the material blocking assembly comprises an air cylinder arranged on the support; a piston rod of the air cylinder is provided with a baffle sliding into and out of the S-shaped channel. The material guiding assembly comprises a material guiding plate rotationally connected to the lower end of the S-shaped channel and a limiting unit used for limiting and fixing the material guiding plate, and the material guiding plate turns over on the vertical face. When the air cylinder drives the baffle to do one-time linear reciprocating motion, materials on the lowest side of the serpentine channel roll to the positioning mechanism from the materia
