Processing method of fiberglass seat for urban rail vehicles

Abstract

The invention discloses a machining method of an urban rail vehicle glass fiber reinforced plastic seat. The machining method includes the steps that resin, glass fiber, flame retardants and auxiliaries are mixed according to the proportion of design and are pressed into material blocks; a seat back mold used for molding the lower layer of the seat and a seat face mold used for molding the upper layer of the seat are adopted, connecting fasteners through which the seat and a support are connected are installed on the seat face mold, and the material blocks of a certain weight are weighed or the material blocks of a certain size are cut and are respectively laid on the seat face mold and the seat back mold; compressing molding is performed, and semi-finished products of the lower layer of the seat and the upper layer of the seat are formed; rough edges of the semi-finished products are trimmed after demolding; and the lower layer of the seat and the upper layer of the seat are bonded. Due to the application of the machining method of the urban rail vehicle glass fiber reinforced plastic seat, batch production can be achieved, and therefore production efficiency can be obviously improved, production cost can be saved, the surface quality of the product obtained through the compression molding technology is good, environmental pollution is small, and weight controllability of the seat is high.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, and more specifically, relates to a method for processing a fiberglass seat of an urban rail vehicle. Background technique [0002] With the increasingly serious problems of traffic congestion, travel inconvenience, and environmental pollution, the concept of giving priority to the development of public transportation has been recognized by more and more people. Urban rail transit is an important part of public transportation and the main way for people to travel daily. Urban rail transit generally refers to a transportation system in which vehicles run on fixed guide rails in cities and are mainly used for urban passenger transportation. It has the following advantages: it has a large transportation capacity and can transport a large passenger flow in a short period of time; it has high punctuality and can make passengers reach their destination quickly, shortening the travel time...
