Description

Technical Field

[0001] This utility model belongs to the technical field of ship hull processing equipment, and in particular relates to a bending device suitable for ship ridges of different shapes. Background Technology

[0002] In shipbuilding engineering, the stern generally refers to the main supporting structure of the hull, similar to the human spine, and plays a core role in the strength and stability of the hull. The hull ribs are important supporting components in the ship's hull structure and are a core component of the hull's transverse skeleton system. They are mainly used to enhance the hull's transverse strength and rigidity, support the outer plating, and maintain the hull's shape.

[0003] The bending processes for ship hull ribs include cold bending on a support bed and rolling bending on a three-wheeled bending machine, which are difficult to control in terms of processing accuracy and are not suitable for workpieces requiring high precision. Hot bending forming using a medium-frequency heating rib bending and quenching machine has high equipment costs, strict process control requirements, and low efficiency. On-machine die forming is expensive to manufacture and requires different dies for different rib shapes, resulting in poor flexibility. Water-fire bending and manual bending processes rely heavily on worker experience and skills. Therefore, a bending device suitable for different hull rib shapes is needed. This device should employ the three-point bending principle, using bending dies on two side frames as fulcrums, while the bending die on the middle frame applies bending force to the profile from both ends. By feeding and bending segment by segment, the overall bending and forming of the rib can be achieved. Utility Model Content

[0022] In the following description, embodiments of the bending device of the present invention applicable to ridges of different shapes will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates a bending device for ship ridges of different shapes, according to an embodiment of the present invention. It includes a base 1; side supports 2 are fixedly installed on both sides of the top of the base 1; a first hydraulic cylinder 3 is fixedly installed on the top of the inner cavity of the side supports 2; a side pressure head 4 is fixedly connected to the output end of the first hydraulic cylinder 3; limit guide rails 5 are fixedly connected to both ends of the rear side of the inner cavity of the side supports 2; the side pressure head 4 is slidably connected to the limit guide rails 5; and a guide rail adapted to a middle support 7 is installed on the top of the base 1. The limit guide rails 5 limit and guide the side pressure head 4, and the guide rails limit and guide both the limit guide rails 5 and the middle support 7, thereby improving the performance of either the limit guide rails 5 or the middle support 7. To ensure stability during the sliding displacement process, a side support block 6 is fixedly installed at the bottom of the inner cavity of the side support 2, located directly below the side pressure head 4. A slidable central support 7 is provided on the top of the base 1. A bellows cover 14 is fixedly connected to the front side of the top of the base 1, and the rear side of the bellows cover 14 is fixedly connected to the front side of the central support 7. The bellows cover 14 covers the surface of the guide rail. A hydraulic station 8 is provided on the left side of the base 1. A second hydraulic cylinder 16 is fixedly installed on the top of the inner cavity of the central support 7, and a central pressure head 10 is fixedly connected to the output end of the second hydraulic cylinder 16. A central support block 11 is fixedly connected to the bottom of the inner cavity of the central support 7. A feed cylinder 15 is fixedly installed on the rear side of the base 1. The feed cylinder 15... The output end is fixedly connected to the rear side of the middle support 7. An electrical control cabinet 12 is set at the rear end of the right side of the base 1. A display 13 is fixedly installed on the right side of the base 1. Material conveying components 9 are set on both sides of the base 1. The material conveying components 9 include two triangular support frames 91. A conveying roller 92 is rotatably connected to the top of the inner cavity of the triangular support frame 91. A rotating column 93 is rotatably connected to the bottom of the rear side of the inner cavity of the triangular support frame 91. A transmission chain 94 is fixedly connected to the surface of the rotating column 93. A force-bearing chain 95 is fixedly connected to the rear side of the surface of the conveying roller 92. The transmission chain 94 and the force-bearing chain 95 are connected by a chain. A drive chain 96 is fixedly connected to the rear side of the surface of the rotating column 93. Two adjacent drive chain 96 are connected by a chain. A servo motor 97 is fixedly installed on the rear side of the triangular support frame 91 on the side away from the base 1. The output shaft of the servo motor 97 is fixedly connected to the rear end of the rotating column 93. Through the setting of the material conveying assembly 9, the triangular support frame 91 and the conveying roller 92 work together to support the rib plate and facilitate the user to move the rib plate. At the same time, under the drive of the servo motor 97 and the linkage and transmission of the rotating column 93, the transmission chain 94, the force-bearing chain 95 and the drive chain 96, the conveying roller 92 is driven to rotate, so that the conveying roller 92 can generate a certain frictional transmission force on the rib plate, which makes it convenient for the user to adjust the loading, unloading or bending position of the rib plate.

[0024] Working Principle: When using this invention, the user, with the assistance of the feeding assembly 9, moves the rib plate to the top of the base 1 and into the designated processing position. Then, the first hydraulic cylinder 3 starts and drives the side pressure head 4 to move up and down along the limiting guide rail 5, causing the bottom of the side pressure head 4 to contact the top of the rib plate. Simultaneously, the bottom of the rib plate contacts the top of the side support block 6. Under the opposing clamping action of the side pressure head 4 and the side support block 6, the rib plate is clamped and fixed. Then, the second hydraulic cylinder 16 opens and drives the central pressure head 10 downwards, clamping it in the middle of the rib plate. Then, the feed cylinder 15 starts and pushes the central support 7 back and forth, causing displacement. During the back and forth displacement, the central support 7 compresses the middle of the rib plate, allowing the rib plate to be fully bent under the three-point bending principle. During the bending process of the rib plate, the side support block 6... The rib plate rotates at a certain angle following the deformation direction of the rib plate, thus preventing the side pressure head 4 and the side support block 6 from being relatively fixed in their connection positions, which could lead to excessive weakening of the rib plate thickness at the bending position. After bending and forming, the first hydraulic cylinder 3, the second hydraulic cylinder 16, and the feed hydraulic cylinder 15 all retract, causing the side pressure head 4, the middle pressure head 10, and the middle support 7 to reset. Subsequently, the servo motor 97 starts and drives the rotating column 93 to rotate. Under the meshing transmission action of the second chain and the drive chain 96, the transmission chain 94 rotates. At the same time, under the transmission action of the transmission chain 94 and the first chain, the force-bearing chain 95 rotates, which in turn causes the conveying roller 92 to rotate on the top of the triangular support frame 91, thereby assisting the user in moving the rib plate. After it is moved into place, the clamping and pressing steps are repeated to bend the subsequent workpieces segment by segment until the required curvature of the entire workpiece is achieved.

[0025] In summary, this bending equipment, suitable for ribs of different shapes, clamps both sides of the rib plate through the combined use of the side support 2, the first hydraulic cylinder 3, and the side pressure head 4. Simultaneously, the middle support 7, the middle pressure head 10, the feed hydraulic cylinder 15, and the second hydraulic cylinder 16 work together to compress the middle of the rib plate. Thus, through the three-point bending principle, the rib plate is fully formed, achieving the purpose of bending rib plates of different shapes and processing in different bending directions.
