Problems solved by technology
Pipe benders are mainly used for bending steel pipes and other materials, and play an important role in the laying and repair of pipes in boilers, bridges, ships, furniture, decoration, etc. Due to the limitation of the mold, the arc cannot be bent at will. For example, if it is a perfect circular mold, the curved arc can only be a perfect circle, but not an elliptical arc. If you want to bend other arcs, you can only change the mold. It causes waste of materials and increases in cost, and also reduces production efficiency.
In addition, due to the influence of the structure, the traditional pipe bending machine can only process flat products, the efficiency is low, the product quality is unstable, and it is not suitable for mass production; the scope of use is small, and it cannot meet the existing diversified products, such as steel pipes and clamping devices. The contact point with the bending table is prone to slipping, which affects the normal bending and bending accuracy of the steel pipe

Embodiment Construction
[0030] Such as Figure 1 to Figure 8 As shown, a pipe bending machine used in the production of steel pipes includes a frame 2 and a workbench 1. The workbench 1 is located on the frame 2, and the workbench 1 is provided with a bending guide rail 13 and a bending table 3. The outside of the workbench 1 is provided with an arc-shaped photoelectric switch fixing plate 9, and the arc-shaped photoelectric switch fixing plate 9 is provided with a photoelectric switch 10, and the side of the outer clamping control room 5 is provided with a stopper 11, and the photoelectric switch 10 and the stopper 11 matches. By installing the arc-shaped photoelectric switch fixing plate 9 on the outside of the bending table 3, when the bent pipe 20 enters the bending space 40, the photoelectric switch 10 sends a signal to start working, and immediately starts the first cylinder 41 and the second cylinder of the clamping device 42. Clamp the pipe 20 to be bent, and reflect the degree of clamping t...

The invention discloses a pipe bending machine used in the production of steel pipes, which comprises a frame and a workbench. Clamping device, the clamping device includes a clamping control room and a clamping seat, the clamping control room includes an inner clamping control room and an outer clamping control room, and the clamping seat includes an inner clamping seat and an outer clamping seat, on the curved guide rail There is a curved slider, the upper end of the curved slider is connected to the outer clamping control room, and the outer clamping control room is fixedly installed on the curved slider. The curved inclined rail is provided with a rotating shaft at the lower end of the bending table, and the rotating shaft is connected with a power driving device. Through the clamping device, the inner clamping seat and the outer clamping seat match and clamp the pipe to be bent to prepare for bending the pipe to be bent. Through the bending guide rail and the bending slider, the outer clamping control room can work together with the outer clamping seat during the bending process of the pipe to be bent.
Description
technical field [0001] The invention relates to a pipe bending processing equipment, in particular to a pipe bending machine used in the production of steel pipes. Background technique [0002] Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines and so on. Pipe benders are mainly used for bending steel pipes and other materials, and play an important role in the laying and repair of pipes in boilers, bridges, ships, furniture, decoration, etc. Due to the limitation of the mold, the arc cannot be bent at will. For example, if it is a perfect circular mold, the curved arc can only be a perfect circle, but not an elliptical arc. If you want to bend other arcs, you can only change the mold. It causes the waste of materials and the increase of cost, and also reduces the production efficiency. In addition, due to the influence of the structure, the traditional pipe bending machine can only process flat products, the effici...
