The drum type trailer axle brake bottom plate manufacturing process comprises a drum type brake shaft body assembly, a brake bottom plate and a shaft body, and the drum type brake shaft body assembly is composed of the brake bottom plate, the shaft body, a brake air chamber support and a cam shaft support; the brake bottom plate is made of Q355. The manufacturing process of the brake bottom plate comprises the following steps that S1, plate shearing is conducted; s2, polishing is conducted; s3, deburring is conducted; s4, heating and cleaning; s5, stamping and crimping; s6, heating and punching; s7, cooling and shaping; and S8, secondary grinding is conducted. The Q355 material is selected as the raw material of the brake bottom plate, so that the brake bottom plate has good forming, plastic extension, welding and cutting, high-temperature and anti-fatigue performance, the service life is long, and the product quality is very stable. 本发明公开了一种鼓式挂车车桥制动底板制造工艺，包括鼓式制动轴体总成、制动底板和轴体，所述鼓式制动轴体总成由制动底板、轴体、制动气室支架和凸轮轴支架构成；
