Abstract

The invention relates to a method for manufacturing a coatrack of an automobile, which pertains to the technical field of automobile interior trim parts; the method comprises the steps: a natural fiberboard is taken as a board body of the coatrack; press forming, cool setting, fabric attaching, die cutting and accessory mounting are carried out to the board body of the coatrack. The board body is claimed as a finished product after passing the examination. The method of the invention achieves the performance indexes of a coatrack assembly, such as heat resistance, light weight, high strength, low contractility and low deformability and reaches the Grade 3 of the international leading level, thereby reducing the weight of the coatrack and meeting the design requirement of light weight of the whole automobile; the process adopts the double-oven suspension heating and molding line production, with stable technique; a semi-automatic assembling fixture is adopted in the installation, thereby ensuring safe accuracy and improving working efficiency. No semi-manufactured goods accumulate during the course so that the manufacturing cost can be saved. No harmful substance is generated in the whole production process so that the coatrack produced by the method of the invention is environment-friendly.

Description

technical field [0001] The invention relates to a production method of an automobile coat rack (rear shelf), specifically, it is used to install behind the automobile seat and below the rear windshield to play the role of being able to put items and be beautiful, and belongs to the interior of the automobile. Trim technology field. Background technique [0002] Automotive interior parts are generally installed on the top of the car, the trunk, and the cab to play the role of heat insulation, sound insulation, aesthetics and practicality. 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 low weight and high strength of coat racks become bottlenecks, r...
