Description

Technical Field

[0001] This utility model belongs to the field of semi-circular tube processing technology, and in particular relates to a bending and forming device for semi-circular tube processing. Background Technology

[0002] A semi-circular tube is a tubular structure with a semi-circular cross-section, usually made of materials such as metal. It combines the function of pipeline transportation with the characteristics of conforming to curved surfaces. It is widely used in chemical, mechanical and other processes. The bending and shaping of semi-circular tubes is mainly to adapt to specific installation spaces or equipment structures, such as conforming to cylindrical cylinders, arc shells and other curved surface components, to improve space utilization and structural compactness. At the same time, bending and shaping can optimize the fluid flow path, enhance heat transfer and transportation efficiency, and also meet the form requirements of protection, support and other functions, ensuring efficient adaptation in chemical, mechanical and other scenarios.

When bending, the metal tube may deviate due to excessive bending force, resulting in a change in the bent shape, which is difficult to meet the expected requirements and reduces the stability of the device during use.

The device further includes: a guide section mounted on the working plate; a bending section disposed on the working plate; the guide section includes a guide assembly mounted on the top of the working plate; and a transmission assembly mounted on the guide assembly; the guide assembly includes two guide blocks disposed on the top of the working plate, and a mounting frame is fixedly connected to the top of the working plate, with a movable component disposed on the mounting frame; wherein four support legs are provided, linearly distributed on the working plate, and the guide assembly is used for initial guidance and limiting support of the metal tube.

[0007] Furthermore, the bent portion includes a connecting assembly mounted on a work plate; and a bending assembly mounted on the connecting assembly; wherein the bending assembly passes through the connecting assembly.

[0008] Furthermore, the transmission assembly includes two racks slidably connected to the top of the mounting bracket, a gear is rotatably connected to the top of the mounting bracket, and a rotating component is provided on the mounting bracket; wherein, both racks mesh with the gear, and the transmission assembly provides power and transmission for the movement of the guide block in the guide assembly.

[0009] Furthermore, the connecting assembly includes a connecting frame fixedly connected to the top of the work plate, the connecting frame being fixedly connected to the mounting frame on the side near the mounting frame, two pressing rollers being provided on the top of the work plate, the pressing roller on the right being fixedly connected to the connecting frame, and a motor frame being fixedly connected to the bottom of the work plate. The connecting assembly provides a stable mounting base for the bending assembly.

[0010] Furthermore, the bending assembly includes a second motor that passes through the motor frame, the outer wall of the second motor being fixedly connected to the motor frame, a rotating rod passing through the top of the working plate, the output shaft of the second motor being fixedly connected to the rotating rod via a coupling, a fixing plate passing through the outer wall of the rotating rod, the outer wall of the rotating rod being fixedly connected to the fixing plate, a moving rod being fixedly connected to the top of the fixing plate, a support plate being fixedly connected to the top of the moving rod, the outer wall of the rotating rod being fixedly connected to the support plate, and a bending component being provided on the rotating rod; wherein, the pressing roller located on the left side is fixedly connected to the top of the support plate.

[0011] Furthermore, the guide includes a connecting rod fixedly connected to the top of the work plate, and a guide rod is fixedly connected to the top of the work plate.

Finally, the metal tube is restricted between the two guide blocks, completing the guiding work. During the bending of the semi-circular tube, the metal tube is limited and guided to avoid the metal tube from shifting due to excessive bending force when entering the bending stage, which would cause the bending shape to change and make it difficult to meet the expected requirements, thus improving the stability of the device during use.

The fixed plate and the moving rod cooperate to drive the support plate and the bending block to rotate around the rotating rod. During this period, the two pressing rollers cooperate to bend the metal tube, and finally complete the bending and forming of the metal tube. In the process of bending the semi-circular tube, the metal tube is bent and formed at multiple angles to avoid the fixed bending angle, which makes it difficult to adapt to different bending requirements and improves the efficiency of the device.
