Adjustable flexible processing device and curved plate forming method for ship curved plate processing

Abstract

The invention discloses an adjustable flexible processing device and a curved plate forming method for ship curved plate processing, comprising the upper die and the lower die of symmetrical layout, wherein the upper die and the lower die comprise at least one unit respectively, and each of the unit body comprises an outer frame and a screw rod. Many screw rodsare arranged on the outer frame side by side and are movable relative to the outer frame. One end of each screw rod is hinged with the flexible head, and the adjacent flexible heads are flexibly connected to form chain structure. The adjustable flexible processing device and curved plate forming method for ship curved plate processing also provides a method to form curved plate by using the above adjustable flexible processing device. By setting the unit with a flexible head, the adjustable flexible processing device and curved plate forming method for ship curved plate processing can meet the processing requirements of shell plate with great curvature variation between the head and the tail. The structure is simple, practical, and convenient for disassembly and assembly. The adjustable flexible processing device and curved plate forming method for ship curved plate processing can be repeatedly used and widely used.

Description

technical field [0001] The invention relates to a ship manufacturing tool and a forming method, more specifically, to an adjustable flexible processing device and a curved plate forming method for processing curved plates of ships. Background technique [0002] The forming process of the hull plate has always been one of the most complicated processes in the hull manufacturing, and the quality of the forming process directly affects the performance of the ship. [0003] At present, for the processing of complex outer plates at the bow and stern, three-core rollers or hydraulic presses are usually used for bending and forming, and outer plates with bidirectional curvatures such as bow and stern sail plates and saddle plates must be processed in the direction of larger curvature. On the basis of one-way roll bending, water and fire bending is performed on the other direction with smaller curvature. The water and fire bending is locally heated by a heat source, and at the same ...

AI Technical Summary

Problems solved by technology

[0004] In order to meet the processing requirements of special materials in high-tech products and avoid water and fire processing, special processing molds must be made, but because the manufactured molds are not universal and relatively single, if the number is large, the production cost is expensive, and it is not suitable for flexible production in small batches. Moreover, it takes up the storage space, so it has always been one of the problems hindering the improvement of shipbuilding efficiency.
