Description

A bending machine for manufacturing ship hulls Technical Field

[0001] This utility model relates to the technical field of ship hull manufacturing equipment, and in particular to a bending machine for ship hull manufacturing. Background Technology

[0002] Ship hulls are mostly constructed from steel plates and other metal products, requiring bending machines for deep processing during manufacturing. For example, application number CN201921738832.8 discloses a bending device for processing ship cabinets, including a base, a worktable fixedly mounted on the upper surface of the base, a bending groove on the upper surface of the worktable, a frame welded to the upper surface of the worktable, a cylinder fixedly mounted on the upper surface of the inner sidewall of the frame, and a bending head fixedly mounted on the piston rod of the cylinder via a mounting plate. By setting up a support plate, sliding rod, spring a, movable plate, spring b, fixed block, U-shaped mounting seat, and positioning plate, and utilizing the elastic action of springs a and b in conjunction with the hinge action of the fixed block and U-shaped mounting seat diameter, the cabinet panel can effectively prevent the ends from warping during bending, ensuring bending accuracy and preventing cabinet panel displacement during bending.

[0003] However, there are many shapes of existing ship hulls, so when processing them with a bending machine, it is necessary to frequently change the bending head for processing. In the past, the molds were manually disassembled and assembled by mechanics, which was very troublesome, time-consuming and labor-intensive. It was impossible to quickly and effortlessly change the bending molds. Moreover, some bending machines are prone to causing the hull to get stuck on the bending mold during processing, making it difficult to demold the hull and impossible to perform quick and effortless demolding. Therefore, a bending machine for manufacturing ship hulls is provided. Summary of the Invention
