Description

Technical Field

[0001] The utility model relates to the technical field of rubber, in particular to a cutting device for producing rubber sealing rings. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a large molecular weight, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed from gum extracted from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry and life.

A circular mounting through hole is provided on the fixed plate, and the cylindrical mounting frame is installed in the through hole. The disc-type tool fixing frame is fixed to the horizontal support plate through the bracket. A limiting groove is provided on the disk surface of the disc-type tool fixing frame, and the arc-shaped blade is installed in the limiting groove. The fixed end of the servo motor is fixed on the bracket, and the controller is electrically connected to the servo motor; the leg group is fixed to the bottom of the cutting main unit.
