[0002] Carbon brush is a kind of sliding contact part, which is widely used in various electrical equipment. The main materials used in carbon brush products are graphite, impregnated graphite, and metal graphite. Carbon brushes are usually made by mixing and pressing a variety of raw materials such as natural graphite powder, artificial graphite powder, and conductive carbon black. The carbon brush pressing and molding device in the prior art is mainly composed of a frame, a support table, a hydraulic press, a feeding structure, a punch and a die. When in use, the punch is pressed into the die under the action of the hydraulic press, thereby molding the carbon brush powder in the die.
[0003] When the existing pressing device is in use, powder is added into the die.
