Description

Technical Field

[0001] The utility model relates to the technical field of graphite carbon brush forming equipment, in particular to a graphite carbon brush forming machine. Background Technique

[0002] The graphite carbon brush forming machine is a device specifically used for producing graphite carbon brushes. The working principle of the graphite carbon brush forming machine mainly involves steps such as mixing, pressing, and forming of raw materials. The raw materials such as graphite powder are mixed evenly in a certain proportion, and then the mixture is pressed into a carbon brush blank with a specific shape and density through a pressing device. Finally, through further processing and treatment, such as sintering, grinding, etc., a graphite carbon brush product that meets the requirements is finally obtained.

[0003] After the raw materials are mixed, a powder feeding box is required to be sent to the pressing place, which can transport the pre-mixed raw materials such as graphite powder to the forming die regularly and quantitatively. After that, it is pressed into shape. When feeding the powder, the product processed in the previous pressing step will be pushed out. When it is pushed out to the discharging place, there will be residual powder on the forming table or the top of the die. The residual powder may adhere to the just-formed graphite carbon brush product, causing surface contamination of the product and affecting the appearance quality and cleanliness of the product. If the residual powder on the discharging path of the product is cleaned, this will increase the downtime and cleaning cost in the production process, and improvement is needed. In view of the above problems, a graphite carbon brush forming machine is proposed. Content of the Utility Model
