Abstract

The invention relates to a method for producing a wheel arc shield for an automobile. The method is characterized by comprising the steps of spreading a material for the wheel arc shield, drying the material, press forming, cutting a semi-finished product and cutting the semi-finished product into a finished product by a water jet. The method solves the problems of sound absorption, heat resistance, weight lightness, high strength and other performance indexes of a wheel arc shield assembly, greatly reduces the weight of the wheel arc shield, meets the requirement of a light weight design forthe whole automobile, adopts single oven suspension drying in a process of drying the material, has stable process to ensure safety and accuracy of operation, and improves the operation efficiency atthe same time; the product has high rigidity, and cannot be broken or droop; no semi-finished product is accumulated in the process so as to save manufacture cost; and the product does not generate harmful substances in the whole production process.

Description

technical field [0001] The invention relates to a production method of an automobile wheel arc cover, in particular, it is used for being installed on the wheel arc of the automobile to play the functions of heat insulation, sound insulation and beautification, and belongs to the technical field of automobile interior decoration parts. Background technique [0002] The automobile wheel arch cover is installed on the wheel arc of the automobile, which plays the role of heat insulation, sound insulation and beautification. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as high sound absorption, low grammage, and high strength of the wheel arch cover hav...
