Brake is a component of the braking system used to generate braking force that hinders vehicle movement or movement trend. In addition to various retardation devices, almost all automobile brakes are friction brakes that utilize the friction between the fixed element and the working surface of the rotating element to generate braking torque. At present, all kinds of automobiles widely used friction brake according to the different rotating elements can be divided into two categories: drum type and disk type. The difference between them is that the rotating element in the friction pair of the drum brake is the brake drum, with its cylindrical inner surface as the working surface, and the rotating element in the friction pair of the disk brake is the disc-shaped brake disk, with its two end surfaces as the working surface. The basic shape of the brake drum is in the form of a drum with attachment holes on the mounting surface, as shown below: We have supplied centrifugal casting equipment to several domestic brake drum manufacturers. Chinese domestic brake drum manufacturers usually adopt the method of spinning the inside of the drum with steel plate, set with centrifugal casting of alloy cast iron parts, the combination of brake drums. For the structure diagram A - steel plate, B - cast iron lining ring
This equipment is used for centrifugal casting of automobile bimetallic composite brake drums, The equipment will brake drum steel shell through the centrifugal casting process in the inner wall of a layer of wear-resistant materials, so that the brake drum will significantly improve the strength and abrasion resistance than the traditional cast iron brake drum,and can improve the braking safety of the car. The equipment has a high degree of automation, high production efficiency, a small footprint, and other characteristics. 1) 8 centrifugal casting machines are evenly distributed on the rotary table, and the process of clamping, heating, pouring, cooling, and unloading of brake drum is completed by rotating the rotary table; 2)The centrifugal casting machines are equipped with automatic clamping devices for brake drums; 3) Equipped with automatic heating device for brake drum steel shell; 4) Equipped with an automatic casting device for brake drum steel shell to complete the automatic compound casting of wear-resistant layer; 5)Equipped with brake drum steel shell loading and casting brake drum unloading robot; 6). Equipped with PLC automatic control system to realize the automatic production of the whole process.
