The structure generally includes two bottom supports and an upper support. The upper support is located in the middle of the two bottom supports. The pipes are placed above the two bottom supports, and then move downward through the upper support to achieve the purpose of bending. This structure can refer to the arc bending device for processing automobile air-conditioning condenser pipes disclosed in the prior art (announcement) No.: CN216175591U.

[0008] A vertical lifting rod is fixedly connected to the top surface of the first support member, the lifting rod is fixedly connected to the lifting end of the power lifting device, and the elastic thrust mechanism is installed between the lifting rod and the second support member.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-2A condenser pipe bending device includes two bottom support members 1, an upper support member, and a power lifting device capable of driving the upper support member to move up and down. The upper support member includes a first support member 4 and second support members 5 symmetrically arranged at both ends of the first support member 4. The lifting end of the power lifting device is fixed to the first support member 4, and the second support member 5 is rotatably connected to the first support member 4 through a third hinge 14. An elastic thrust mechanism 3 is installed between the second support member 5 and the first support member 4. The elastic thrust mechanism 3 can make the bottom surface of the second support member 5 elastically press against the condenser pipe.

[0019] refer to Figure 1 , place the pipes to be bent on the two bottom supports 1, and then move the upper support downward. Since the second support 5 is rotatably connected to the first support 4, an elastic thrust mechanism 3 is installed between the second support 5 and the first support 4, which enables the bottom surface of the second support 5 to elastically abut against the condenser pipe. Figure 2 As the first support member 4 applies downward pressure, the second support member 5 rotates upward due to the reaction force of the pipeline. Therefore, compared with the traditional upper support member with one force point, this device can make the upper support member have more force points, so that the force is more uniform when the pipeline bends.

[0020] As an embodiment, a vertical lifting rod 2 is fixedly connected to the top surface of the first support member 4, and the lifting rod 2 is fixedly connected to the lifting end of the power lifting device, and an elastic thrust mechanism 3 is installed between the lifting rod 2 and the second support member 5; specifically, the elastic thrust mechanism 3 includes a first support rod 7 and a second support rod 12, one end of the first support rod 7 is rotatably connected to the lifting rod 2 through a first hinge 6, the other end of the first support rod 7 is rotatably connected to one end of the second support rod 12, and the other end of the second support rod 12 is rotatably connected to the second support member 5 through a second hinge 13, and an elastic member is installed between the first support rod 7 and the second support rod 12, and the elastic member can generate an elastic force that causes the first support rod 7 and the second support rod 12 to move to an extended state. The first support rod 7 and the second support rod 12 are in a state where they can be elastically rotated by the elastic member, and as the first support member 4 applies downward pressure, the first support rod 7 and the second support rod 12 gradually tend to a bent state.

[0021] As an embodiment, the elastic member is a torsion spring, which includes a main body 9, a first end 8, and a second end 11. The first support rod 7 and the second support rod 12 are rotatably connected via a connecting shaft 10. The main body 9 is mounted on the connecting shaft 10, the first end 8 abuts against the first support rod 7, and the second end 11 abuts against the second support rod 12. The torsion spring is used to put the first support rod 7 and the second support rod 12 in an elastically extended state.

[0022] The first support member 4 is a first arc-shaped plate, and / or the second support member 5 is a second arc-shaped plate. The arc-shaped plates can make the curved portion of the finally formed pipeline more uniform and more fixed in shape.

[0023] The power lifting equipment is a power telescopic cylinder, such as a pneumatic cylinder or a hydraulic cylinder.

[0024] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto.
