Processing technology of automobile wheel hub:
Brake drum and wheel hub are widely used in cars, so what are the specific construction techniques? Longyao xiangyuan auto parts co., LTD.
Wheel processing is one of the most important safe parts on the car, has the branch of steel wheel and aluminum wheel hub, wheel cars and cargo quality work under pressure, is the role of vehicle dynamic torque when starting, braking and also take cars turning in the process of driving, roads, road barrier impact of dynamic load from different directions such as the irregular alternating stress. Quality and reliability of the wheel not only relates to the safety of vehicles and goods of the personnel on the car, also affect the stability and maneuverability, the comfort of vehicles on the road, such as performance, this requires a good hub of dynamic balance, high fatigue strength, good rigidity and flexibility, high precision size and shape, weight, etc., aluminum wheel hub, with its good comprehensive performance can meet the above requirements, in terms of safety, comfort and lightweight, wins the market, is gradually replace steel wheel as the best choice.
Aluminum wheel manufacturing equipment, technology and trends of automobile aluminum wheel the most important production process is: melting refining material inspection low-pressure casting X-ray inspection heat treatment mechanical processing dynamic balance inspection air tightness inspection coating.
The melting equipment of aluminum alloy wheel hub is divided into tower furnace, induction furnace, tilting converter and fixed furnace according to furnace type, and diesel, natural gas, coal-to-gas and electric energy according to energy form. Tower furnace has high melting speed, low burning loss and low energy consumption. Induction furnace melting speed, alloy composition uniformity, good production environment; Tilting converter can be batching can also do insulation furnace use, use safety, easy maintenance; Fixed furnace can be batching can also do insulation furnace use, use and maintenance is simple; High calorific value of fuel oil, high melting efficiency, easy to use and maintain, good gas production environment, clean, easy to use and maintain; Coal - to - gas economy, easy control of electricity, good production environment. The tower type rapid melting furnace with fuel oil or gas is preferred, and the aluminum chip melting chamber is more convenient to use. It is the main equipment of choice.
