Large aluminum alloy wheel hub forging hydraulic press

Abstract

The invention relates to a hydraulic machine for forging and forming a large-sized aluminium alloy wheel hub. The hydraulic machine comprises a framework structure machine body consisting of an upper beam, struts and a lower beam which are fastened by pull rod locking nuts, wherein a band cylinder sliding block and a return cylinder are fixedly arranged on the upper beam; a jacking cylinder is arranged on the lower beam; an upper fixed base plate is arranged below the band cylinder sliding block; and a lower fixed base plate is arranged on the lower beam. The hydraulic machine is characterized in that an upper heat isolation plate and an upper heating plate are arranged between the upper fixed base plate and an upper die; a lower heat isolation plate and a lower heating plate are arranged between the lower fixed base plate and a lower die; and the side faces of the struts of the machine body are connected with a visible operation safety door. The hydraulic machine has the advantages that heat loss of the hydraulic machine during forging can be effectively avoided, so that a die can forge a workpiece in a proper temperature region, and the mechanical property and the physical property of a wheel hub piece are greatly improved; overall visible operation of the hydraulic machine can be realized; and injury of harmful gas and fog to an operator can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of forging machinery, in particular to a large aluminum alloy wheel hub forging hydraulic press. Background technique [0002] With the development of modern industry, more aluminum alloys are used in civil and commercial applications. Based on the characteristics of aluminum alloy: Compared with steel alloy, under the same volume and shape, the overall weight is reduced and the physical properties are improved. Especially in various fields such as automobiles, aircrafts, bridges, and mechanical machine tools, it has developed rapidly. Aluminum alloy wheels are a revolutionary progress in the development of automobiles. The reduced weight of the whole vehicle can not only greatly reduce energy consumption, achieve the effect of energy saving and emission reduction, but also reduce the loss of wheels to tires and increase the service life of tires . However, the temperature range of aluminum alloy pressing is relati...

Problems solved by technology

Because this substance is very easy to produce smoke and toxic and harmful gases, it has a toxic effect on the human body. Operators need to wear protective masks when operating. However, because the surrounding environment has been polluted by release for a long time, the protective masks are only simple protection and cannot be used. To achieve the real protection of workers' health, in many cases, this kind of environmental pollution has caused great harm to the health of operators
