Description

Technical Field

[0001] The utility model belongs to the technical field of pipe bending devices, and in particular relates to a pipe bending device for mechanical processing. Background Art

[0002] Bending pipe fittings is a type of mechanical processing. In the production process of pipe fittings, facing different needs, the requirements for pipe fitting processing are also correspondingly improved.

[0003] For example, the Chinese patent with the publication number CN210231124U discloses a pipe bending device for mechanical processing, including a workbench, a pipe bending mechanism and a pipe fixing mechanism, the bottom of the pipe fixing mechanism is fixedly connected to the top of the workbench, the pipe bending mechanism includes a vertical shaft, a bottom plate and a top plate, the top of the workbench is provided with a through hole, and the inner wall of the through hole is fixedly connected with a bearing, the vertical shaft is embedded in the bearing, the top of the vertical shaft is fixedly connected with the bottom plate, the top of the bottom plate and the top plate are provided with two groups of plug holes, the two plug holes on the bottom plate and the two plug holes on the top plate are both plugged with threaded columns, and one end of the threaded column is threadedly sleeved with a nut, and the end of the threaded column away from the nut is fixedly connected with a circular plate. The utility model is a device for bending pipes during mechanical processing, which is easy for staff to operate and has good safety performance, thereby improving the safety of the device.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when in use, such as: the above-mentioned device can only process one end of the pipe fitting. When it is necessary to process both ends of the pipe fitting, only one end of the pipe fitting can be processed first, and then the other end of the pipe fitting can be processed for the second time. At the same time, the personnel also need to adjust the position where the pipe fitting needs to be placed and fix it again. This process is quite cumbersome, which greatly reduces the work efficiency of pipe bending. Moreover, the above-mentioned pipe fixing mechanism is two identical and independent devices. In actual use, the personnel need to pass the pipe fitting through the two independent devices to the appropriate position, and then rotate the two threaded rods in turn to fix it. The operation is relatively troublesome, which reduces the work efficiency of the personnel. In view of this, we propose a pipe bending device for mechanical processing. Utility Model Content
