Abstract

The invention discloses a process equipment and method for manufacturing end walls of low-floor vehicles, which are used in the manufacture of end walls of low-floor vehicles with large arcs, and mainly include: tires, positioning devices, and pressing devices; tires of the tires The surface is flat and provided with a plurality of chute, the positioning device can be fixed on the chute of the tread through fasteners, and the pressing device is installed on the tread; the present invention uses multiple sets of The above-mentioned positioning device can quickly and accurately locate the processed large-radian end wall and end corner column, and by setting multiple sets of the above-mentioned pressing device, distributed multi-point pressing on the end wall board ensures its flatness and obtains good processing quality .

Description

technical field [0001] The invention relates to the field of vehicle equipment manufacturing, in particular to a process equipment and method for manufacturing an end wall of a low-floor vehicle. Background technique [0002] With the development of urban rail construction, the demand for rail transit vehicles is increasing day by day. In order to facilitate passengers to get on and off and travel, the development of low-floor trams is vigorously promoted at this stage. At present, some vehicle structures adopt a large number of arc designs, and the connection Hinged form. However, this brings higher requirements to the manufacture of the steel structure of the end wall. The outer arcs on both sides of the steel structure of the end wall must fit the profile of the side wall of the car body. The flatness of the outer plate and the installation dimensions of the hinged device. With the traditional platform type, the curvature of the end wall shape cannot be guaranteed, and ...
