Description

Technical Field

[0001] The utility model relates to the technical field of motor carbon brush processing, in particular to an automatic profiling forming machine for large motor carbon brushes. Background Art

[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 multiple raw materials such as natural graphite powder, artificial graphite powder, and conductive carbon black. The existing carbon brush pressing and forming device is mainly composed of a frame, a workbench, a hydraulic press, a feeding structure, a punch and a die.

[0003] The patent application of Jianjingsuo in the publication (announcement) number: CN105437454A discloses a pressurized molding machine for producing motor carbon brushes, including a box body, a base and an end cover. A stirring mechanism, a pressurized molding mechanism, a support platform and a pressurized molding platform are arranged in the box body. The support platform is fixedly connected to the top surface of the base, and the pressurized molding platform is rotatably connected to the support platform. A pneumatic discharging mechanism is arranged on the side of the box body. The stirring mechanism and the pressurized molding mechanism are both connected to the end cover. A hydraulic oil tank is arranged on the end cover. The hydraulic oil tank is connected to the pressurized molding mechanism through an oil inlet pipe and an oil outlet pipe. A slide rail is arranged below the hydraulic oil tank. The pressurized molding mechanism is connected to the slide rail through a slider. The invention has a simple structure and strong practicality. It can not only make the discharging of the stirring barrel, the extrusion of the pressurized molding mechanism and the pushing of the pneumatic discharging mechanism synchronous, thereby improving the working efficiency of the pressurized molding mechanism, but also can recycle the dripping raw materials, and at the same time can meet the processing and production of carbon brushes of different models and sizes.

[0004] Although the above scheme can make the discharging of the mixing barrel, the extrusion of the pressure forming mechanism and the pushing of the pneumatic discharging mechanism proceed synchronously, thereby improving the working efficiency of the pressure forming mechanism, it is rather troublesome to remove the carbon brush after it is formed, and the working efficiency is low. Therefore, we propose a large motor carbon brush automatic profiling forming machine. Utility Model Content

[0015] Preferably, the demoulding unit comprises a connecting groove provided on a side wall of the forming groove, and a shielding plate movably arranged in the connecting groove.

[0016] Compared with the prior art, the utility model has the following beneficial effects:
