Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending devices, in particular to an assembled galvanized pipe bending device. Background Art

[0002] Prefabricated galvanized pipes refer to steel pipes that have been galvanized for assembly construction. This type of steel pipe has good anti-corrosion properties. A layer of zinc is formed on the surface of the steel pipe through the galvanizing process, which can effectively protect the steel pipe from rust. These galvanized pipes can be pre-processed and assembled, and then quickly installed and connected on site to improve construction efficiency and quality.

[0003] During assembly, galvanized pipes need to be bent using a bending device. However, the existing larger galvanized pipe bending devices are not convenient to be transported to the installation site for use at any time. Small bending devices are difficult to bend galvanized pipes with specifications above DN25, resulting in galvanized pipes with deformation above DN25 at the installation site cannot be used and need to be returned to the processing site for re-bending, which seriously affects the installation efficiency of the galvanized pipes. Therefore, in response to the above problems, we propose a new type of assembled galvanized pipe bending device. Utility Model Content

An assembled galvanized pipe bending device is proposed.

[0023] The effect achieved by the entire embodiment 1 is that the bottom plate 1 in the device is 80 cm long and 60 cm wide, and the overall height of the device is 80 cm, with a moderate volume and convenient transportation. When in use, long steel bars can be found at the installation site to be inserted into the steel bar insertion hole 13 on the surface of the bottom plate 1 to increase the contact area between the bottom plate 1 and the bottom surface, and steel pipes or other suitable steel components can be found and inserted into the socket 508 to increase the length of the power arm. When in use, the galvanized pipe is inserted between the upper support block 41 and the lower support block 22 at the position where it needs to be bent and passes over the first rotating wheel 21, and then the steel pipe power arm is pressed downward to drive the second connecting frame 507 and the connecting member 501 to rotate with the first connecting bolt 12 as the center.

The use effect is good, and the problem that the galvanized pipe cannot be bent at the installation site and affects the installation efficiency is solved. The first connecting frame 4 is mainly used to install the upper support block 41, and is connected to the mounting plate 11 by bolts and can be disassembled. The first bearing sleeve 2 is mainly used to reduce the friction between the first rotating wheel 21 and the first connecting bolt 12.

When the second rotating wheel 506 rotates to the appropriate position, the positioning block 503 on the surface of the connecting member 501 will be resisted by the magnetic pin 31, thereby effectively avoiding the problem of excessive bending. The structure is simple and the practicability is high.

[0026] Working principle: When in use, you can find long steel bars at the installation site and insert them into the steel bar insertion hole 13 on the surface of the bottom plate 1 to increase the contact area between the bottom plate 1 and the bottom surface, find steel pipes or other suitable steel components and insert them into the socket 508 to increase the length of the power arm. When in use, insert the galvanized pipe between the upper support block 41 and the lower support block 22 to pass over the first rotating wheel 21 at the position where the galvanized pipe needs to be bent, and then press down on the steel pipe power arm to drive the second connecting frame 507 and the connecting piece 501 to rotate with the first connecting bolt 12 as the center. At this time, the first rotating wheel 21 will support the bending part of the galvanized pipe, and the second rotating wheel 506 will roll on the surface of the galvanized pipe and press it down, so that the galvanized pipe is bent. The device is designed with conventional dimensions and uses the steel bars and steel pipes at the installation site to increase the contact area between the device and the ground to ensure stability during use. The addition of a power arm ensures that assembled galvanized pipes with specifications above DN25 can be effectively bent. The use effect is good and solves the problem that galvanized pipes cannot be bent at the installation site, which affects the installation efficiency. In addition, when using the device to bend assembled galvanized pipes, the magnetic pin 31 can be inserted into the positioning hole 3 at a suitable position according to the bending requirements.
