Flexible manufacturing line for rail wagons and production process thereof

Abstract

The invention provides a flexible manufacturing line for rail wagons and a production process thereof. The flexible manufacturing line for rail wagons comprises a basic unit arranged along the length direction of rail wagons to be manufactured, the basic unit is connected with a supporting unit in fixed sliding mode, and the sliding direction of the supporting unit is in accordance with the length direction of the wagons to be manufactured. The supporting unit is provided with a clamping unit arranged on the upper portion and a positioning unit arranged on the lower portion. The clamping unit comprises a clamping head used for clamping the rail wagons to be manufactured, and the positioning unit comprises a positioning block which positions lateral walls of the rail wagons to be manufactured from the lateral direction. The manufacturing line is a flexible manufacturing line which is capable of being used for manufacturing various types of rail wagons with one manufacture line, thereby avoiding repetitive input of technological equipment, improving use ratio of technological equipment, and reducing cycle and cost for changing the line of production.

Description

technical field [0001] The invention relates to the technical field of railway freight car production, in particular to a flexible manufacturing line for railway freight cars and a production process thereof. Background technique [0002] Railway wagons are a general term for vehicles used to carry goods on railways. They mainly include gondola cars, boxcars, and funnel cars. The car bodies of the above vehicle types are all composed of main components such as underframes, end walls, and side walls. In the production of railway wagons, the process of "parts first, then assembly" is generally followed, that is, the main components such as the chassis, end walls, and side walls are processed first, and then the main components such as the chassis, end walls, and side walls are assembled. Welding completes the car body. [0003] However, the specific manufacturing process is different for different vehicle types. For example, the body length of a general-purpose gondola car ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a flexible production line for railway wagons to solve the problem that in the prior art, the process equipment of the vehicle production line is relatively rigid, the same production line can only produce the same type of railway wagons, and different models of the same type are produced with shorter lengths. Railway wagons will cause some planar resources to be idle, and the problems of repeated investment in process equipment, low utilization rate of process equipment, long conversion cycle and high conversion cost
