Abstract

The invention relates to the field of rail transit, in particular to a rail transit composite material vehicle body forming tool. The tool comprises a bottom plate, a guide structure and a movable sliding block set, a cavity is enclosed by the movable sliding block set, workers enter and exit from the cavity, the guide structure is fixed to the bottom plate, the movable sliding block set can slide along the guide structure, the movable sliding block set is provided with a movable male die molded surface used for laying prepreg, and the male die molded surface is arranged on one side away from the cavity. According to the tool and the method, through the arrangement of side edge sliding blocks and angle edge sliding blocks, demolding is easy and fast through outward demolding, and when the prepreg is manually laid on the outer side of a die, the operation is convenient. The movable male die molded surface is arranged on one side far away from the cavity, so that the prepreg paved on the male die molded surface is heated uniformly and quickly, and the heating time in the autoclave is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit composite car body molding tool and a molding method thereof. Background technique [0002] The existing rail transit vehicle body mainly adopts the metal structure car body, but due to the limitation of the quality, performance and cost of the metal structure car body, in order to meet the growing new demand of rail transit, the rail transit lightweight building is gradually developed Become a new trend of rail transit. The new composite material car body is divided into multi-section car bodies for winding and laying intermediate unit modules, end walls and other components. However, there is no molding tooling corresponding to the composite material car body. A rail transit composite car body molding tool that is easy to operate is a technical problem that those skilled in the art need to solve at present. In view of the above problems, based on years of ...
