Problems solved by technology
Even if cracks, etc. are not generated, the bulk density in the upper and lower parts, and the core is not uniform, and the strength is low, so it is not suitable for use as a carbon brush
Carbon brushes with uneven volume density are prone to wear compared with carbon brushes with uniform volume density in the upper, lower, and core parts, and have the disadvantages of poor rectification performance and short brush life.

Embodiment 1
[0045] Add 25 parts by weight of thermosetting resin to 100 parts by weight of artificial graphite powder with an average particle diameter of 40μm, and pulverize the agitated mixture to an average particle diameter of 200μm to prepare powder for resin-bonded carbon brush molding. Mitochondria. The continuous automatic powder press molding device described in the specific embodiment molds four such carbonaceous molding powders and granules at a time.
Embodiment 2
[0047] A continuous automatic powder press molding device with the above U-shaped groove formed not only on the lower punch but also on the upper punch was produced, and four resin-bonded carbon brush powders used in Example 1 were molded at a time.

Description
Technical field [0001] The present invention relates to a powder and granular forming device, a method for forming a powder and granular body using the forming device, and a formed body obtained by the forming method. Specifically, it relates to no stripes or wrinkles, surface and core A molded body with a small difference in molding density of the part is used for a molding device and a molding method for obtaining such a molded body. Background technique [0002] For example, take carbon products as an example. Carbon products have excellent heat resistance, corrosion resistance, thermal conductivity, electrical conductivity, self-lubricating properties, etc., and are widely used in metallurgy, electrical discharge machining, semiconductor, atomic force, sliding and other industries. Among them, electrical and mechanical brushes that utilize sliding properties and self-lubricating properties are used in various fields. [0003] Hereinafter, electric and mechanical brushes will ...
