Abstract

The invention relates to a friction block production device and a friction block production method. The friction block production device comprises a mixing mechanism, a pressing and forming mechanismand a pressing and sintering mechanism, wherein the mixing mechanism mixes and stirs materials to form a mixed material; the pressing and forming mechanism comprises a pre-pressing mechanism and a primary pressing mechanism;, the pre-pressing mechanism pre-presses the mixed material, the primary pressing mechanism re-presses the pre-pressed mixed material and the pressure of the pre-pressing mechanism is smaller than a pressure value of the primary pressing mechanism; and the pressing and sintering mechanism pressurizes and sinters the pressed and formed mixed material. The friction block production device solves the problem that the compact density of a friction block is low and the friction block even has cracks as the compact will expands elastically to increase the volume as a result of release of elastic stress after an existing friction block is pressed.

Description

technical field [0001] The invention relates to the technical field of friction block production, in particular to a friction block production device and a friction block production method. Background technique [0002] The friction block is the core part of the brake pad. It is composed of two parts: the friction body and the steel back of the friction block. High temperature and high pressure sintering is used to combine the friction body and the steel back of the friction block. The steel back of the friction block is machined and formed from steel. The friction body is made of copper as the matrix, adding iron powder, graphite and a small amount of other metal elements. Using powder metallurgy technology, it is produced and processed through mixing, pressing and sintering. [0003] The pressing method of the friction block in the prior art adopts a one-shot forming method. After the compact is removed from the pressure or demolded, due to the release of the elastic stre...
