[0002] Train brake shoes and brake pads are important components in the train braking system, mainly used to control the braking and deceleration of the train to ensure the train's driving safety. When the driver operates the braking system, the brake shoes will rub against the wheels or gears of the train, causing the train to gradually slow down and eventually stop. Brake shoes are usually composed of friction materials, linings, support plates and other parts. According to the type of friction material, they can be classified into two types: powder metallurgy and organic synthesis. No matter which type, it requires batching and pressing processes.

[0003] Most of the existing pressing processes use four-column presses to produce brake shoes and brake pads through pressing molds.
