Abstract

The present invention relates to double curvature plate cold pressing formation method and apparatus. The formation process includes the following steps: determining the rebound elasticity of cold pressed steel plate, determining the curvature radius and size of upper and lower working plates, setting plate material, cutting, pressing, etc. The formation apparatus includes upper pressing mold, lower pressing mold, reinforcing ribbed plates welded onto the top plate, upper working plate, lower working plate and bottom plate, and oil press. The present invention makes it possible to produce high quality double curvature plate with smooth surface.

Description

(1) Technical field

[0001] The invention relates to a double-curvature plate forming technology, in particular to a method and device for cold-pressing a double-curvature plate. (2) Background technology

[0002] The double-curvature plate structure is mostly used for metallurgical furnace shells and containers with special requirements in the metallurgical industry. The plates used in this double-curvature structure should have high high temperature strength and good creep resistance, and are mostly thick and high yield limit. The low-alloy steel, the required pressing force is large. The current plate bending machine can only form a single-curvature plate, and a double-curvature plate cannot be formed on the plate bending machine, and there is currently no special pressing device for cold-pressing of a large-scale furnace shell double-curvature plate in China. (3) Contents of the invention

[0003] The technical problem to be solved by the present invention is to provid...
