Sectional type composite material vehicle body skin pasting tool and technology

Abstract

The invention relates to the technical field of rail transit vehicle bodies, in particular to a sectional type composite material vehicle body skin pasting tool and process, the tool comprises two rotation driving devices, a rotating shaft is arranged between the two rotation driving devices, the rotating shaft is detachably connected with at least one rotation driving device, and the two rotation driving devices drive the rotating shaft to rotate; the rotating shaft is detachably provided with a plurality of supporting assemblies in the length extending direction, and the multiple supporting assemblies support the interior of the vehicle body. Wherein at least one rotary driving device is arranged on the working plane in a sliding mode, slides in the length extension direction of the rotary shaft and gets close to or away from the other rotary driving device. According to the method, laying of the composite material outside the segmented vehicle body is achieved, a foundation is provided for curing forming of the overall outer skin of the subsequent segmented vehicle body, and the structural strength and the connecting strength of the segmented vehicle body are improved.

Description

technical field [0001] The invention relates to the technical field of rail transit car bodies, in particular to a segmented composite material car body skin-clad tooling and a process. Background technique [0002] With the development of raw materials and progress in technology, the cost of composite materials in rail transit applications is gradually decreasing; at the same time, due to the characteristics of composite materials such as fatigue resistance and corrosion resistance, maintenance and repair costs are reduced; due to weight reduction, operations are improved. capacity, reduced energy consumption, and reduced life cycle costs. [0003] The application in rail transit gives full play to the superior characteristics of carbon fiber composite materials, and uses lighter materials to complete the same structural design as metal materials, so that the weight of the whole vehicle is greatly reduced compared with similar stainless steel or aluminum alloy vehicles, the...

AI Technical Summary

Problems solved by technology

[0004] Due to the large size of the rail transit car body, it is formed as a whole or divided into end walls, side walls, and bottom walls. For composite materials, a large mold or autoclave is required for curing and molding. , on the one hand, molding is difficult and costly, and on the other hand, it is difficult to guarantee the molding quality o
