Method for manufacturing hump plate for mounting railway bridges, involves arranging frames at edge on sheet metal plate and on support, and deforming sheet metal plate into boss plate by introducing fluid into cushion

摘要

The method involves clamping a sheet metal plate (8) on the supports (4,5). The frames (9,10) are placed at the edge on the sheet metal plate and are arranged on the support by which the fluid is acted upon with a cushion (6). The sheet metal plate is deformed into a boss plate by introducing a fluid into the cushion. The sheet metal plate is clamped on the frame such that at the sheet-metal plate during deformation relative to the frame is slipped. An independent claim is included for device for manufacturing hump plate.
