Problems solved by technology

Because the quality of various components in the mixed raw material is different, when the raw material falls from the hopper into the material box, the components in the raw material will be mixed unevenly, which will lead to poor uniformity of the final pressed carbon brush, carbon brush Poor performance in delivering energy or signals

Embodiment Construction

[0016] The present invention will be described in further detail below by means of specific embodiments:

[0017] The reference signs in the drawings of the description include: hydraulic cylinder 1 , rack 2 , gear 3 , stirring shaft 4 , roller 5 , chute 6 , and helical blade 7 .

[0018] The embodiment is basically as attached figure 1 with figure 2 Shown: a stirring device for a carbon brush press forming machine, including a power and transmission structure and a stirring structure installed on the forming machine. The power and transmission structure can be a cylinder or a hydraulic cylinder 1, a rack 2 and two The gear 3 meshed with the rack 2, because the hydraulic cylinder 1 moves relatively smoothly, so the hydraulic cylinder 1 is used in this embodiment, and the piston rod of the hydraulic cylinder 1 is welded to one end of the rack 2; the stirring structure includes a stirring shaft located in the material box 4 and stirring blades, the stirring shaft 4 is connect...

Abstract

The invention discloses a stirring device for a carbon brush pressing forming machine. The stirring device comprises a power and transmission structure and a stirring structure mounted on the forming machine, the power and transmission structure consists of an air cylinder or hydraulic cylinder, a toothed rack and a plurality of to gears able to engage with the toothed rack, and the piston rod of the air cylinder or hydraulic cylinder is connected to one end of the toothed rack. The stirring structure includes stirring shafts and stirring blades located in a material box, the stirring shafts are provided with a plurality of stirring blades, each gear is in connection with one of the stirring shafts, and each stirring shaft is rotatably connected to the forming machine. The stirring device provided by the invention can mix the raw material components evenly, thereby ensuring the quality of a press formed carbon brush.

Description

technical field [0001] The invention belongs to the field of producing molded products from materials by using a press, and in particular relates to a stirring device for a carbon brush press molding machine. Background technique [0002] Carbon brush (Carbonbrush), also called electric brush, is widely used in many electrical equipment as a sliding contact. Carbon brushes are mainly used in graphite, fat-impregnated graphite, and metal (copper, silver) graphite. Carbon brushes are usually made of natural graphite powder, artificial graphite powder, conductive carbon black and other raw materials mixed and pressed. [0003] Carbon brushes are usually pressed with a press molding machine, including a hopper, a die, a punch and a material box, etc., and the evenly mixed raw materials are added to the hopper, and the raw materials fall from the hopper into the material box, and the material box moves and pushes the material into the concave mold In the process, the raw materi...
