Description
Technical Field
The invention relates to the technical field of commercial vehicle roofs, in particular to an easy-to-clean high-toughness commercial vehicle roof and a manufacturing method thereof.
Background
The automobile interior ceiling is positioned between the top of the head of a passenger and the shell of the automobile, is an interior trim part with the largest area of the middle plane of the automobile interior, has a decorative effect for modern automobiles, and plays roles of protecting the head of the passenger, blocking noise transmitted from the top of the automobile from entering the automobile and absorbing the noise generated in the automobile. Therefore, the ceiling interior is a very specific indication of different injuries to various parts of the human body, and therefore different interior materials are used in different places where the interior of the automobile is in contact with the human body. taking hard top car as example, the three materials of facing, foam layer and base are compounded together into a shaped member by hot press forming method and mounted on the car roof by adhering or embedding method, wherein the facing material mainly adopts fabric, TPO, and the above materials are not easy to clean. With the further understanding of automobiles, automobile noise becomes a very important automobile quality index, and directly influences the sale condition and the acceptance of automobiles. Therefore, it is necessary to study the easy cleaning of the ceiling and the high toughness to reduce the noise.
At present, most of the domestic existing vehicle ceilings adopt non-woven fabrics, knitted fabrics, PU plates and hemp plates. The two groups of materials have the disadvantages that the surface layers of the non-woven fabric and the knitted fabric are easy to dirty and not easy to clean, and the PU plate and the hemp plate are easy to absorb moisture and mildew, are easy to deform and influence the attractiveness; in order to meet the requirements of heat insulation, sound absorption, touch, safety and low cost of the ceiling, the development of a ceiling for a vehicle, which is easy to clean and has high toughness and good noise reduction performance, is an urgent problem in the field.
Disclosure of Invention
The invention aims to solve the technical problem that the technical defects exist, and provides an easy-to-clean high-toughness commercial vehicle ceiling and a manufacturing method thereof, wherein the commercial vehicle ceiling is of a composite structure; the surface layer is made of PVC fabric; the bottom layer is a light GMT plate; the light GMT plate can be recycled, so that the generation of solid waste is reduced, and the light GMT plate has a plurality of excellent performances such as high toughness, heat insulation, sound absorption and the like, so that the light GMT plate meets the light weight requirement of vehicle materials.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the commercial vehicle roof adopts a composite structure; the surface layer is made of PVC fabric; the bottom layer is a light GMT plate.
Further optimizing the technical scheme, the manufacturing method comprises the following steps:
(1) material working procedure: firstly, sequentially pre-cutting a PVC fabric and a light GMT plate by a cutting tool according to the size of a product report;
(2) hot press molding: firstly, heating and softening the cut light GMT plate by an oven, then placing PVC fabric on the upper part of the softened light GMT plate, and then placing the compound of the light GMT plate and the PVC fabric on a forming die for pressing operation, so that the shape which is consistent with the sheet metal part at the corresponding position of the vehicle is obtained, and a semi-finished product of the commercial vehicle roof is obtained;
(3) the edge cutting and hole cutting process comprises the following steps: firstly, placing a semi-finished product of a commercial vehicle ceiling on the upper part of a water cutting mould, and then performing cutting hole site and edge treatment on the semi-finished product of the commercial vehicle ceiling by using a water jet cutter which is pre-programmed with a processing procedure according to the requirements of a drawing;
(4) a sticking procedure: and (4) carrying out pasting accessory treatment on the commercial vehicle ceiling semi-finished product subjected to the water cutting treatment, thereby obtaining the commercial vehicle ceiling.
Compared with the prior art, the invention has the following advantages: 1. the light GMT plate selected by the invention can be recycled, so that the generation of fixed wastes is reduced; 2. the electric baking oven baking and the hot press molding are adopted, so that the production environment is not polluted, the ceiling molding effect is good, and the two materials are more firmly adhered; 3. the light GMT plate selected by the invention has a plurality of excellent performances of high toughness, heat insulation and sound absorption, thereby meeting the light weight requirement of the vehicle material.
