Abstract

The invention discloses an automobile roof sunroof reinforcement frame and a hot die stamping forming process thereof. The automobile roof sunroof reinforcement frame includes a base material; and thebase material at least includes a layer of core material made of a high-molecular polymer material having a hole-opening structure, the core material preferably selects a PU material, an upper reinforcement layer and a lower reinforcement layer is bonded on both sides of the base material, the surface of the upper reinforcement layer is bonded with a scarfskin layer, the bottom surface of the lower reinforcement layer is bonded with a bottom cloth layer, the upper reinforcement layer and the lower reinforcement layer are made of at least one layer of fiber glass filaments or glass fiber felt,and the automobile roof sunroof reinforcement frame adopts the hot die stamping forming process. Raw materials of the automobile roof sunroof reinforcement frame are made of the PU material and glassfiber, the automobile roof sunroof reinforcement frame is light in weight, enables the production cost to be greatly reduced, saves energy and is environmentally friendly, and conforms to the trend of light-weight development of an automobile industry; and at the same time, the hot die stamping forming process is adopted, steps of the process are simple, operation is convenient, and while the dimensional stability of the sunroof reinforcement frame is improved, and the production efficiency is also greatly improved.

Description

technical field [0001] The invention relates to a component of the roof of an automobile, in particular to a sunroof reinforcement frame of the roof of an automobile and a hot die stamping forming process thereof. Background technique [0002] With the rapid development of modern society, the energy crisis is becoming more and more serious. Energy conservation and environmental protection are two major issues today. In the past, the car roof sunroof reinforcement frame played the role of strengthening the strength of the roof sunroof and connecting the roof and the body sheet metal. The traditional sunroof reinforcement frame is made of PC+ABS, ABS+30% GF or galvanized metal sheet, which is heavy, high cost, and complicated molding process; and it is easy to mix with the sheet metal and cause abnormal noise. Contents of the invention [0003] The object of the present invention is to provide a car roof sunroof reinforcement frame to solve the problems of heavy weight and ...
