When the pipe is required to be formed, firstly, the sheet to be bent is placed on the workbench 1 and corresponds to the position below the pipe forming press rod 4, and then, when the bending head 3 moves towards the sheet, the sheet can be coated on the pipe forming press rod 4, so that a tubular structure is formed. The pipe molding press rod 4 is detachably connected with the pressing driving mechanism 41, so that the pipe molding press rod 4 can be replaced according to the requirement, and the processing requirement of rolling and molding of pipes with different shapes can be met.
In some embodiments of the present invention, the pipe molding press rod 4 is arc-shaped as a whole, and the diameters of the cross sections of the pipe molding press rod 4 may be equal from beginning to end, or may be unequal, so that the diameters of the sleeves formed by rolling the sheet material in different areas of the pipe molding press rod 4 may be adjusted arbitrarily according to the different sizes of the pipe molding press rod 4, thereby meeting the processing requirements of the sleeves with various different size requirements.
Referring again to fig. 4 and 5, in some embodiments of the present invention, the pressing driving mechanism 41 connected to the pipe molding press 4 is a corner pressing cylinder. The corner compacting cylinder is arranged at the center of the guide disc 2, can drive the pipe molding compression rod 4 to compact the sheet to be bent, can drive the formed pipe to rotate away from the bending area, and is convenient for taking down the finished pipe.
Referring to fig. 6, in some embodiments of the present invention, a profiling head 31 is disposed at one end of the bending head 3 near the sheet to be bent, and one end of the profiling head 31 near the sheet to be bent has an arc surface, which can be matched with or different from the size of the pipe molding press rod 4, so that when the bending head 3 moves towards the pipe molding press rod 4, the sheet can be wrapped on the outer surface of the pipe molding press rod 4 and form a pipe initially.
