Abstract

The invention provides a centrifuge and relates to the field of manufacturing of an automobile part. The centrifuge comprises a support, a centrifugal casting chamber and an overturning mechanism, wherein the overturning mechanism comprises an overturning frame, a speed changer and a transmission mechanism; the overturning frame is arranged on the support; a motor is used for driving the overturning frame to overturn relative to the support by the transmission mechanism and the speed changer; a locking reshaping block, a centrifugal casting mechanism and a rotation mechanism are arranged in the centrifugal casting chamber; the rotation mechanism comprises a transmission mechanism and a speed changer; a main motor is used for driving the locking reshaping block and the centrifugal casting mechanism to rotate relative to the centrifugal casting chamber by the transmission mechanism and the speed changer. The invention further provides a process for manufacturing an anti-cracking type composite brake drum by the centrifuge. The process adopts a special centrifugal casting manner and the manufactured brake drum has high bearing capability, good anti-cracking performance and long service life.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to a centrifuge and a process for manufacturing a crack-proof composite brake drum by using the centrifuge. Background technique [0002] The traditional one-piece cast drum brake is widely used in trucks at present. The brake is mainly composed of a brake drum and a brake shoe. It uses frictional resistance to convert the kinetic energy of the car into heat energy, thereby slowing down or driving the car. Stop to ensure safe driving. When the car is heavy-loaded and driving at high speed, especially when going down a long or steep slope, due to the large braking force and multiple consecutive brakings, the temperature of the inner wall of the brake drum rises sharply, and the temperature difference between the inside and outside increases, and the material of the brake drum The high temperature mechanical properties also drop sharply. The thicker the brake drum wall, the g...
