Abstract

The invention provides a double-curvature saddle-shaped plate compression molding tooling applied to the technical field of double-curvature saddle-shaped plates for ships. The double-curvature saddle-shaped plate compression molding tooling comprises an upper die (1) and a lower die (2); the upper die (1) comprises an upper die base plate (3), a plurality of upper die transverse partition plates (4) and a plurality of upper die longitudinal partition plates (5); and the lower die (2) comprises a lower die base plate (10), a plurality of lower die transverse partition plates (11) and a plurality of lower die longitudinal partition plates (12). The double-curvature saddle-shaped plate pressing forming tooling provided by the invention is simple in structure, pressing forming of the double-curvature saddle-shaped plate can be conveniently and rapidly achieved, the quality of pressed finished products is effectively guaranteed, the tooling manufacturing time is shortened, the expenditure is reduced, the machining difficulty is reduced, labor intensity is reduced, energy consumption is saved, and construction period is controlled.

Description

technical field [0001] The invention belongs to the technical field of double-curvature saddle-shaped boards for ships, and more specifically relates to a press-forming tool for double-curved saddle-shaped boards. Background technique [0002] The processing of ship outer plates often encounters that the double-curvature saddle-shaped plates cannot be accurately processed and formed, and the smooth fit cannot be guaranteed after repeated processing. Due to the changeable shape of the saddle-shaped plate, it is difficult to process it in place. Usually, the processing method of cold bending combined with water and fire bending is used. The steel plate is deformed by cold bending, heating and cooling, and the sample plate and sample box are used as the processing basis for processing. Due to manual operation, the difficulty is high, the production efficiency is low, the processing cycle is long, the pass rate is low, and frequent rework affects the production cycle. The doubl...
