The invention discloses an automobile axle housing. The automobile axle housing adopts a light alloy and is an integrally molded part. The invention also provides an automobile axle housing extrusionforming method, sectional extrusion is adopted, a pre-forged blank is a magnesium alloy or an aluminum alloy, the pre-forged blank is placed in a cavity of a die, the die is assembled and locked, thedie is heated and subjected to heat preservation, a multi-directional die forging press drives a punch in the horizontal direction or the vertical direction of the die to extrude the blank, the punchis stopped after travelling a part of the stroke, the multi-directional die forging press drives a punch in the other direction of the die to extrude the blank, after extrusion is completed, the multi-directional die forging press continues to drive the punch in the horizontal direction or the vertical direction of the die to extrude the blank, and the remaining stroke is completed. The inventionfurther provides an automobile axle housing extrusion forming die, an automobile axle housing can be manufactured by multi-directional extrusion of a magnesium alloy or an aluminum alloy, the manufacturing difficulty is lowered, the requirement of light weight is met, the material utilization rate is high, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of extrusion molding, in particular to an automobile axle housing, an extrusion molding method and a mold thereof. Background technique [0002] With the rapid development of the automobile industry, energy saving and environmental protection have become the mainstream direction of automobile development. Automobile lightweight is of great significance for energy saving, emission reduction, environmental protection, and improvement of vehicle stability. Experiments have shown that for traditional fuel vehicles, every 100 kg reduction in vehicle weight can reduce fuel consumption by 0.3-0.6 liters per 100 kilometers. For pure electric vehicles, every 100 kg reduction in vehicle weight can increase mileage by 10%, saving battery costs by 15 %-20%. [0003] The axle housing is the basic part for installing the main reducer, differential, half shaft, hub and suspension, and its main function is to support and ...
