Description

Technical Field

[0001] This utility model relates to the field of pipe bending device technology, and more specifically, to a pipe bending device that can switch the bending direction left and right. Background Technology

[0002] Pipe bending refers to the process of plastically deforming metal pipes according to a certain bending radius and angle. It is widely used in power construction, railway and highway construction, bridges, ships, furniture, and decoration. The quality of pipe bending directly affects the safety and reliability of the pipeline system; therefore, appropriate pipe bending equipment and processes are required.

[0003] For example, Chinese Patent Publication No. CN114247784A discloses a pipe bending device, which includes a housing. A driven shaft is rotatably connected to the middle of the housing and is arranged vertically in the axial direction. The upper end of the driven shaft passes through the top of the housing and the worktable in sequence and is then connected to the guide wheel. One end of the worktable is provided with a bending wheel that cooperates with the guide wheel to perform pipe bending operations. When bending the pipe, the steel pipe passes through the groove between the guide wheel and the bending wheel. By driving the driven shaft to rotate, the worktable, the guide wheel, and the bending wheel on the worktable can be driven to rotate around the axial center of the driven shaft, thereby realizing the bending of the steel pipe.

[0004] The technical solution described in this paper adopts a combined design structure in which the hydraulic cylinder drives the guide wheel and the bending wheel on the workbench to rotate via gear transmission, thereby realizing the automatic bending operation of the steel pipe between the guide wheel and the bending wheel. This saves time and effort, reduces the intensity of manual labor, and effectively improves production efficiency. However, when using this solution, the pipe can only be bent in one direction and does not have the function of switching the bending direction left and right. When it is necessary to change the bending direction, the mold needs to be reinstalled and replaced, which is time-consuming and labor-intensive.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a pipe bending device that can switch the bending direction left and right, in order to achieve a more practical purpose. Utility Model Content

[0007] This utility model is implemented as follows:

[0008] A pipe bending device capable of switching the bending direction left and right includes a frame, a pipe conveying mechanism, and a robotic arm loading mechanism. The bottom end of the pipe conveying mechanism is connected to the top end of the frame, and one side of the frame is connected to one side of the robotic arm loading mechanism. A left-right switching mechanism is installed on one side of the frame. The left-right switching mechanism includes a support side frame, a screw lifting mechanism is installed on one side of the support side frame, a side plate is installed at the lifting end of the screw lifting mechanism, a screw translation mechanism is installed on one side of the side plate, a support plate is installed at the translation end of the screw translation mechanism, a support frame is installed on one side of the support plate, pipe clamping mechanisms are installed on both sides of the support frame, an electric rotating mechanism is installed at one end of the support frame, a first pipe bending die is installed at the top end of the support frame near the electric rotating mechanism, a second pipe bending die is installed at the top end of the first pipe bending die, the bending directions of the first pipe bending die and the second pipe bending die are opposite, and a pipe bending mechanism is installed at the rotating end of the electric rotating mechanism.

[0012] Furthermore, the pipe clamping mechanism includes a fixed side frame, a lifting frame slidably connected to one side of the fixed side frame, a movable plate slidably connected to the top of the lifting frame, a fixed plate installed at the top of the movable plate, and a clamping plate slidably connected to one side of the fixed plate.

[0013] Furthermore, a second hydraulic rod is installed at the bottom end of the fixed side frame, and the output end of the second hydraulic rod is connected to the bottom end of the lifting frame.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the lifting frame can be hydraulically raised and lowered by connecting the output end of the second hydraulic rod to the bottom end of the lifting frame.

[0015] Furthermore, a third hydraulic rod is installed on one side of the bottom end of the lifting frame, and a second connecting rod is hinged to the output end of the third hydraulic rod. One end of the second connecting rod is hinged to the bottom end of the movable plate.

[0017] Furthermore, a fourth hydraulic rod is installed on one side of the fixing plate, and the output end of the fourth hydraulic rod is fixedly connected to one side of the clamping plate.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by fixing the output end of the fourth hydraulic rod to one side of the clamping plate, the position of the clamping plate can be adjusted, which facilitates the clamping and fixing of the pipeline.

[0019] The beneficial effects of this utility model are as follows: This utility model provides a pipe bending device that allows for left-right switching of the bending direction. A side plate is installed at the lifting end of the screw lifting mechanism, enabling height adjustment and switching between the first and second pipe bending molds. A support plate is installed at the translating end of the screw translation mechanism, allowing horizontal movement of the support plate and thus horizontal movement of the first and second pipe bending molds, facilitating the use of pipes of different diameters.
