Abstract
Description
Technical Field
[0001] The invention relates to the field of blanking processing of ship bulb flat steel, in particular to a press-forming tool for the end of ship bulb flat steel. Background Art
[0002] For a long time, the end pressing and forming of marine bulb flat steel has been carried out using rib cold bending machine, and this method has many problems. First, the rib cold bending machine is not a special equipment for the end pressing of bulb flat steel. The use of this machine for construction usually requires 5-6 people to work together, resulting in a large waste of human resources; secondly, due to its own structural and functional limitations, the rib cold bending machine cannot perform pressing operations on marine bulb flat steel with a length of less than 2 meters. The end of the bulb flat steel to be pressed needs to be preheated and then hammered into shape. In this process, the preheating and crane transportation greatly reduce the production efficiency and the safety of the production environment; in addition, the ball head of the marine bulb flat steel is generally facing upward after unloading. When the rib cold bending machine is used for pressing, it must be manually turned over so that the ball head faces downward, which increases the labor intensity of the workers; these problems lead to the low efficiency of the pressing operation of marine bulb flat steel and increase the labor intensity of the workers. The current on-site bending and pressing operation of marine bulb flat steel has greatly limited the number of bulb flat steel pressing processes. A new type of tooling is urgently needed to solve the existing problems, improve production efficiency, and reduce the waste of human resources. Summary of the invention
[0003] The purpose of the present invention is to provide a ship bulb flat steel end pressing and forming tooling which can improve the efficiency of ship bulb flat steel pressing work, reduce labor costs, and make the production process more efficient and automated.
[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a ship-use bulb flat steel end pressing and forming tool, comprising a first transmission wheel (1), a first fixing frame (2), a motor (3), a second fixing frame (4), a second transmission wheel (5), a third fixing frame (6), a pressing die (7), a first hydraulic pressure device (8) and a second hydraulic pressure device (9), wherein the first transmission wheel (1), the second fixing frame (4) and the third fixing frame (6) are respectively mounted on the first fixing frame (2), the motor (3) is mounted below the first fixing frame (2), the second transmission wheel (5) is mounted on the second fixing frame (4), the pressing die (7) is connected to the first hydraulic pressure device (8), the pressing die (7) and the first hydraulic pressure device (8) are respectively fixedly connected to the third fixing frame (6), and the second hydraulic pressure device (9) is mounted on the third fixing frame (6).

[0006] The second fixing frame (4) and the second transmission wheel (5) constitute a limit stop device, which is used to limit the longitudinal movement of the ship's bulb flat steel and support the bulb flat steel.
[0007] The third fixing frame (6), the pressing die (7) and the first hydraulic press (8) constitute a pressing hydraulic device. When in use, the first hydraulic press (8) pushes the pressing die (7) to press the ship's bulb flat steel through the drive of the motor (3).
