Abstract

The invention relates to the technical field of automobile wheel hub manufacturing, and particularly discloses a vehicle wheel automatic closed-die forging production line, a vehicle wheel automatic closed-die forging production technology and an aluminum alloy vehicle wheel. The vehicle wheel automatic closed-die forging production technology comprises the steps of bar material saw cutting, bar material preheating, vehicle wheel blank rock rolling pressing, vehicle wheel blank initial forging closed die forging, vehicle wheel blank final forging closed die forging, vehicle wheel blank chambering, window and central hole punching, compound forging, spinning, vehicle wheel blank heat treatment and a vehicle wheel machining. With the vehicle wheel automatic closed-die forging production technology, the pressing technology of aluminum alloy wheels is simplified, the cost, time and manpower needed for secondary machining and shaping in the later period are greatly saved, and the safety andthe working efficiency of equipment in manufacturing are improved; and additionally, workpiece conveying and feeding are accurate in positioning and convenient to operate, the automation degree is high, and therefore, the requirements of an automatic manufacturing technology of aluminum alloy wheels can be met.

Description

technical field [0001] The application relates to the technical field of automobile wheel manufacturing, in particular to an automatic closed die forging production line and production process of aluminum alloy wheels. Background technique [0002] Conventional wheel production techniques in prior art methods are low-pressure casting techniques and gravity casting techniques. The wheel forging process is a new reform of the domestic wheel production process following the traditional gravity, low pressure and other wheel casting processes, which can greatly reduce and eliminate the common problems of conventional casting, and can realize the automation of wheel manufacturing. It is more competitive in the world. The new technology method has a good market application prospect. The automatic closed die forging process of wheels is a new technology newly researched and developed on the basis of open die forging. The difference between closed die forging and open die forging i...
