Description

A high frequency straight seam welded pipe processing and forming device

Technical Field

The invention relates to the technical field of welded pipe production devices, in particular to a high-frequency straight seam welded pipe processing and forming device.

Background Art

When the welded pipe forming device processes the welded pipe, a roll of iron sheet is connected to the forming device, and a folding roller is installed on the forming device. The folding roller is provided with an upper roller and a lower roller. When the iron sheet passes through the folding roller, it is squeezed and folded by the upper roller and the lower roller of the folding roller. Multiple folding rollers are provided with multiple folding shapes. When the iron sheet just enters the folding roller, the two sides are first folded upward, and then the two sides of the folded iron sheet are brought closer to the middle until the two sides of the iron sheet are brought together. At this time, the iron sheet forms a tube, but there is still a gap at the connection between the two sides of the iron sheet. The gap is then welded by the welding equipment, and finally polished and cut to become the straight seam welded pipe sold on the market. When the iron sheet is folded, it is necessary to adjust the shape according to different The shape of the folding roller is set according to the welding pipes of different shapes and sizes. When a set of forming device needs to change the straight seam welded pipe to be produced, the old folding roller needs to be removed and replaced with a new one. The folding roller is divided into an upper roller and a lower roller. The lower roller is generally installed on a fixed shaft seat, and the upper roller is installed on a movable shaft seat. The movable shaft seat is connected to the lifting pull shaft, and the lifting pull shaft can transmit power to make the movable shaft seat rise and fall. The traditional straight seam welded pipe processing and forming device, its lifting pull shaft and the movable shaft seat are connected and fixed by bolts, etc. When the movable shaft seat is to be disassembled, multiple mounting parts need to be removed, which is very inconvenient. After multiple mounting connectors are disassembled, they are easy to lose and confuse, which is not conducive to the next installation and debugging.

The technical content disclosed in the Chinese patent document (publication number: CN112170533A, patent name: universal automatic pipe making machine) is: including a steel strip clamping device, a horizontal roller pressing device, a closing roller pressing device, a shaping device, an automatic grinding device and a straightening device, the steel strip clamping device, the horizontal roller pressing device, the closing roller pressing device, the shaping device, the automatic grinding device and the straightening device are arranged in sequence, and the horizontal roller pressing device, the closing roller pressing device, the shaping device and the straightening device all adopt an adjustable roller pressing structure..... The upper roller position adjustment mechanism includes a first mounting seat, a first screw, a first positioning seat and an upper roller mounting seat, the first mounting seat is sleeved outside the first horizontal upper roller shaft and is rotatably connected to the first horizontal upper roller shaft, the first mounting seat is slidably connected to the horizontal roller press seat, the first screw passes through the first mounting seat and is threadedly matched with the first mounting seat, one end of the first screw is fixedly connected to the first positioning seat, the first positioning seat is sleeved outside the upper roller mounting seat and is rotatably connected to the upper roller mounting seat, and the upper roller mounting seat is sleeved outside the first horizontal upper roller shaft and is fixedly connected to the first horizontal upper roller.

It can be seen from the above implementation scheme that there is no mechanism for facilitating disassembly between the first horizontal upper roller and the first mounting seat of the automatic pipe making machine. Therefore, when replacing the roller group, the first mounting seat needs to be disassembled before the roller group can be disassembled, which is very inconvenient when changing models and can easily lead to loss of parts.
