[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention. Example

[0024] Reference Figure 1-Figure 4 A step-by-step feeding rib bending machine for large ships includes a mounting base 1, which is connected to a fixed base of the bending machine body through a hinged base. A mounting groove 11 is provided on the upper surface of the mounting base 1. The number of the mounting grooves 11 is several, and the plurality of mounting grooves 11 are equidistantly arranged on the upper surface of the mounting base 1. A limiting mechanism 2 is installed on the inner side wall of the mounting groove 11. A bottom groove 12 is provided on the inner bottom surface of the mounting groove 11 on both sides of the limiting mechanism 2. A lifting mechanism 3 is installed on the inner bottom surface of the bottom groove 12; the limiting mechanism 2 includes a connecting rod 21, which is fixedly connected to the inner side wall of the mounting groove 11. The outer surface of the connecting rod 21 The middle part is rotatably connected to a roller 22, and the outer surfaces of the connecting rods 21 on both sides of the roller 22 are slidably connected to slides 23. Springs 26 are provided on the circumferential outer walls at both ends of the connecting rod 21. One end of the spring 26 is fixedly connected to the inner wall of the mounting groove 11, and the other end of the spring 26 is fixedly connected to the outer surface of the slide 23. A pulley 24 is installed in the middle of one side close to the two slides 23; specifically, when the cold bending machine body outputs ship processing materials, the end of the material can be made to pass through the two slides 23 on the limiting mechanism 2, and the movement of the material is facilitated by the rollers 22 and the pulley 24, and the material processed from the output end of the cold bending machine body.

[0025] Reference Figure 1-Figure 4The upper end of the side surface where the two slides 23 are close to each other is provided with an arc groove 25. The lifting mechanism 3 includes an electric cylinder 31, which is fixedly connected to the inner bottom surface of the bottom groove 12. The input end of the electric cylinder 31 is electrically connected to the external power supply. The output end of the electric cylinder 31 is installed with a piston rod 32. The end of the piston rod 32 away from the electric cylinder 31 is fixedly connected to a top plate 33. The outer surface of the top plate 33 is slidably connected to the inner surface of the mounting groove 11. Specifically, when the workpiece is bent at this time, the electric cylinder 31 can be started to make the piston rod 32 drive the top plate 33 to slide upward, so as to lift the workpiece until the workpiece is at the same height as the arc groove 25. At this time, the mounting seat rotates along the bending direction of the material, and the mounting seat 1 drives the hinged seat to rotate, so that the processed material will squeeze the slide 23 on the connecting rod 21 and begin to bend. Compared with CN217858476U in which the processed material is squeezed and bent on the slide, in this application, the lifting mechanism 3 is used to push the processed material to the height of the arc groove 25. Due to the existence of the arc surface of the arc groove 25, the extrusion of the processed material can be restricted to prevent the processed material from detaching from the mounting seat 1. At the same time, it also prevents the processed material from squeezing and damaging the pulley 24 when bending, thereby improving the safety of the ship's processed materials when bending.

[0026] The implementation principle of the embodiment of the segment-feed cold frame bending machine for large ships in this application is as follows:

[0027] When using the device, first connect the external power supply. When the cold bending machine body outputs the ship processing material, the end of the material can be made to pass between the two slides 23 on the limit mechanism 2, and the roller 22 and the pulley 24 are used to facilitate the movement of the material. When the material is processed from the output end of the cold bending machine body, the electric cylinder 31 can be started to make the piston rod 32 drive the top plate 33 to slide upward to lift the processing material until the processing material is at the same height of the arc groove 25. At this time, the mounting seat rotates along the bending direction of the material, and the mounting seat 1 drives The articulated seat rotates, so that the processing material will squeeze the slide 23 on the connecting rod 21 and begin to bend. Compared with the processing material squeezed and bent on the slide in CN217858476U, in this application, the jacking mechanism 3 is used to push the processing material to the height of the arc groove 25. Due to the existence of the arc surface of the arc groove 25, the extrusion of the processing material can be restricted to prevent the processing material from detaching from the mounting seat 1. At the same time, it also prevents the processing material from squeezing and damaging the pulley 24 when bending, thereby improving the safety of the ship processing material when bending.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
