Abstract

The invention relates to a production method of a car engine compartment cover assembly. An engine compartment cover inner plate finished product can be obtained through the steps such as measuring and cutting of sheet stock, pavement of raw materials, hot pressing forming, mold stripping of a semifinished product, cooling stereotyping and blank processing, and an engine compartment cover outer plate finished product is obtained through the steps such as measuring and cutting of sheet stock, pavement of raw materials, hot pressing forming, mold stripping of a semifinished product, cooling stereotyping and blank processing; and a car engine compartment cover assembly finished product is obtained by assembling and splicing the engine compartment cover inner plate and outer plate. The engine compartment cover assembly produced through the method has the advantages that performance indexes such as sound insulation, environmental protection and miniaturization can meet the requirement that no accumulation of semifinished products in the entire production process, and the manufacturing cost is saved; and the entire production process of the product is free from producing harmful substances.

Description

technical field [0001] The invention relates to a production method of an automobile engine compartment cover assembly, which belongs to the technical field of automobile parts production. Background technique [0002] The car engine cover assembly is installed at the front of the car, above the engine compartment; it replaces the body sheet metal, beautifies the appearance of the car and reduces the weight of the whole car. In the era of more and more pursuit of high performance, environmental protection, energy saving, light weight and individualization, the appearance of cars has become an important factor for people to buy cars. Therefore, the requirements for automotive exterior parts are getting higher and higher. In the prior art, performance indicators of the engine compartment cover assembly such as aesthetics, light weight, strong sound insulation, recyclability, and environmental protection have become bottlenecks, restricting the development of the automobile en...
