Technical Field
[0001] This application relates to the technical field of yacht fence processing, and particularly relates to a manual bending device for yacht fences. Background Art
[0002] In order to improve the safety of yachts, fences need to be installed on yachts. Existing fences are generally made of stainless steel pipes. During the manufacturing process, manual cutting, bending, and welding of the pipes are required. When bending, manual bending equipment is generally used.
[0003] In the existing manual bending equipment, when loading and unloading the steel pipe, the position of the bending roller needs to be adjusted to place and remove the steel pipe. The adjustment of the bending roller is generally achieved by rotating the adjusting nut. Frequently rotating the adjusting nut back and forth will cause the problem of the nut slipping. At the same time, the manual labor intensity of adjusting the bending roller back and forth is relatively large, and there will be a spacing error in manual adjustment, resulting in the bending of the steel pipe not being beautiful enough.

[0018] An embodiment of the present application discloses a manual bending device for yacht railings. Refer to Figures 1-3, including a workbench 1, a disc 2 and a swing arm mechanism. The disc 2 is fixed on the workbench 1. A circular groove is provided on the circumferential side of the disc 2. The swing arm mechanism bends the workpiece around the disc 2. A limit block 11 for limiting the pipe is fixed on the workbench 1. The swing arm mechanism includes a swing arm 3 and a pressing wheel assembly installed on the swing arm 3. A rotating shaft 21 is rotatably connected to the middle of the disc 2, and a connecting seat 22 is fixed to the end of the rotating shaft 21. One end of the swing arm 3 is hinged to the connecting seat 22, and the swing arm 3 can be turned up and down. There is a U-shaped groove 31 on the side of the swing arm 3 away from the disc 2. Strip-shaped grooves 311 are provided on both side walls of the U-shaped groove 31. A long rod 4 is fixed to the end of the U-shaped groove 31. Threads are provided on the surface of the end of the long rod 4 close to the U-shaped groove 31. The pressing wheel assembly includes a U-shaped shell 5 and a bending roller 6. The U-shaped shell 5 is movably sleeved on the surface of the U-shaped groove 31, and a through hole is provided at the position of the U-shaped shell 5 corresponding to the long rod 4. Two adjusting nuts 7 are threadedly connected to the surface of the long rod 4, and the two adjusting nuts 7 are correspondingly arranged on both sides of the through hole. A central shaft 8 is rotatably connected to the middle of the bending roller 6, and both ends of the central shaft 8 are fixed to the U-shaped shell 5, and the central shaft 8 is matched and arranged in the strip-shaped groove 311;
[0019] A lifting unit 9 and an annular pressing block 10 are vertically fixed on the workbench 1. The annular pressing block 10 is arranged on the top of the disc 2. The lifting unit 9 is used to drive the annular pressing block 10 to move up and down and hover above the swing arm 3. The annular pressing block 10 is in surface contact with the swing arm 3.
[0020] Referring to Figure 2 , in order to facilitate the return of the swing arm 3, a stop block 23 for limiting the swing arm 3 is fixed on the disc 2.
[0021] Referring to Figure 1 The lifting unit 9 is a cylinder. A balance seat is fixed to the end of the piston rod of the cylinder. A plurality of connecting rods are evenly and obliquely fixed around the balance seat. The annular block is fixed to the bottom ends of the connecting rods.

After that, there is no need to adjust the position of the bending roller 6 during use. During use, lift the long rod 4 upwards. The long rod 4 drives the entire swing arm mechanism to turn upwards. After inserting the steel pipe, lower the swing arm mechanism. The bending roller 6 presses the steel pipe between the disc 2. After that, the cylinder pushes the annular pressing block 10 to move downwards and hover above the swing arm 3. The staff pushes the swing arm mechanism to make a circular motion to bend the steel pipe. After the bending is completed, the cylinder resets, and the staff can lift the swing arm mechanism, so that the bent steel pipe can be easily taken out.
