Pressure moulding machine used for producing carbon brushes for electric motors

Abstract

The invention discloses a pressure moulding machine used for producing carbon brushes for electric motors. The pressure moulding machine comprises a box body, a pedestal and an end cover, wherein a mixing mechanism, a pressure moulding mechanism, a support table and a pressure moulding table are arranged in the box body; the support table is fixedly connected onto the top surface of the pedestal; the pressure moulding table is connected onto the support table in a rotary manner; the side surface of the box body is provided with a pneumatic material discharging mechanism; the mixing mechanism and the pressure moulding mechanism are both connected onto the end cover; a hydraulic oil tank is arranged on the end cover; the hydraulic oil tank is connected with the pressure moulding mechanism through an oil inlet pipe and an oil outlet pipe; slideways are arranged below the hydraulic oil tank; and the pressure moulding mechanism is connected onto the slideways in a movable manner through sliding blocks. The pressure moulding machine is simple in structure and high in practicability; the material discharging of a mixing barrel, the extruding of the pressure moulding mechanism and the material pushing of the pneumatic material discharging mechanism are performed synchronically; the working efficiency of the pressure moulding mechanism is improved; dropping raw materials can be recycled; and meanwhile, processing and production of carbon brushes of different models and sizes can be met.

Description

technical field [0001] The invention relates to the technical field of motor processing, in particular to a pressure forming machine for producing carbon brushes of motors. Background technique [0002] The function of the motor carbon brush is to change the direction of the current, which is divided into DC motor and AC motor. DC motors change the conductive coils of the rotor, thereby changing the rotor poles and changing the motion of the motor. Carbon brushes are mainly used on the commutator or slip ring of the motor as a sliding contact body for leading and leading current. [0003] The carbon brush processing in the prior art is usually directly processed by a molding machine. However, since the raw materials for preparing carbon brushes need to be stirred, the stirring device is separated from the pressurizing molding device, and continuous production of carbon brushes cannot be realized, which reduces production efficiency. Since the mold is fixed, only one size a...

Problems solved by technology

[0003] The carbon brush processing in the prior art is usually directly processed by a molding machine. However, since the raw materials for preparing carbon brushes need to be stirred, the stirring device is separated from the pressurizing molding device, and continuous production of carbon brushes cannot be realized, which reduces production efficiency. Since the mold is fixed, only one size and type of carbon brush can be processed, which has low practicability, and the dripping raw materials cannot be recycled, resulting in a serious waste of resources
