[0020] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0021] Figure 1 Shown is a front view structural schematic diagram of a bending device for small diameter metal pipes according to an embodiment of the present utility model. Figure 2 Shown is a schematic top view of the structure of a bending device for small-diameter metal pipes according to an embodiment of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a bending device for small diameter metal pipes, comprising: a base 1, such as Figure 1 As shown, the base 1 is made of channel steel with the notch placed longitudinally downward; the fixed baffle 2 is fixedly welded to one side of the base 1, for example Figure 1 As shown, the fixed baffle 2 is made of angle steel, one side of which is fixed horizontally, and the other vertical side becomes the fixed baffle 2; the adjusting baffle 3 can also be made of angle steel, and the adjusting baffle 3 is arranged relative to the fixed baffle 2, and the adjusting baffle 3 is adjusted by adjusting the distance from the fixed baffle 2 through the adjusting screw 13, and the end of the adjusting screw 13 is fixed to the adjusting baffle 2 (for example, by welding and fixing the hexagonal nut at the end), and the adjusting screw 13 is passed through the screw connection hole on the fixed baffle 2, and the adjusting screw 13 is fixed to the fixed baffle 2 through the locking nuts 14 arranged on both sides of the screw connection hole; the fixed vertical shaft 5 is fixed The vertical shaft 5 is cylindrical, and the fixed vertical shaft 5 is fixedly welded to the other side of the base 1; the bending radius sleeve 11 is tubular, and the bending radius sleeve 11 is installed at the lower part of the fixed vertical shaft 5; the rotating sleeve 4 is tubular, and the rotating sleeve 4 is installed at the upper part of the fixed vertical shaft 5; the bending cross bar 7 is cylindrical, and the bending cross bar 7 is installed horizontally, and one end of the bending cross bar 7 is vertically welded and installed on the outer circle of the rotating sleeve 4 on the upper part of the fixed vertical shaft 5; and the bending vertical rod 6, the bending vertical rod 6 is cylindrical, and the bending vertical rod 6 is vertically welded to the bending cross bar 7.

[0023] like Figure 1As shown, the distance between the fixed baffle 2 and the adjustment baffle 3 can be adjusted according to the diameter of the bent pipe 10, and the bending radius sleeve 11 determines the curvature radius of the bent pipe 10. Under the rotation of the bending cross bar 7, the bending vertical rod 6 applies force to the bent pipe 10, thereby realizing the bending operation. If it is necessary to change the curvature radius of the bent pipe, since the outer radius of the bending radius sleeve 11 is equal to the bending radius of the bent pipe 10, it is only necessary to replace the bending radius sleeve 11 with the corresponding outer radius according to the bending radius of the bent pipe 10. Therefore, the bending device for small-diameter metal pipes of the embodiment of the utility model can conveniently realize the bending operation of bending metal pipes of different diameters and different bending radii, and the operation is simple and convenient.

[0024] Furthermore, one or more screw connection holes may be provided on the fixed baffle 2, and one or more corresponding adjustment screws 13 may be provided in the one or more screw connection holes to adjust the distance. Figure 2 As shown, in the embodiment of the present utility model, two screw connecting holes and two adjusting screws 13 are provided to adjust the distance.

[0025] Furthermore, if Figure 1 As shown, a chamfer H is provided at the inner lower portion of the bending radius sleeve 11. Since solder will remain below the fixed vertical shaft 5, the chamfer H is provided to prevent the residual solder from affecting the placement of the bending radius sleeve 11.

[0026] Furthermore, if Figure 1 and Figure 2 As shown, a force rod 8 can be installed on the distal end of the bending cross bar 7. The force rod 8 is in the shape of a round tube for easy operation.

[0027] Furthermore, if Figure 1 As shown, an adjustment pad 12 is placed between the adjustment baffle 3 and the bending radius sleeve 11. The adjustment pad 12 is located below the pipe 10 to be bent. The thickness of the adjustment pad 12 is inversely proportional to the diameter of the bent pipe 10, thereby further stabilizing the bent pipe 10.

[0028] Furthermore, if Figure 1 As shown, bending vertical rods 6 with different distances from the fixed vertical axis 5 are set on the upper and lower sides of the bending horizontal rod 7. Figure 1 As shown, if the bent tube 10 is to be bent into a U-shaped tube, different bending uprights 6 can correspond to different tube diameters, thereby achieving the limit of the bent tube 10. If it is necessary to use a different bending upright 6, since the bending cross bar 7 is welded and fixed to the rotating sleeve 4, it is only necessary to turn the bending cross bar 7 over. In addition to the above uses, different bending uprights 6 can also be used to apply different force positions to the bent tube 10. When switching, it is only necessary to turn the bending cross bar 7 over, which is convenient to use.

[0029] In the embodiment of the utility model, an adjustment baffle is provided to meet the needs of bending and clamping of bent metal pipes of different diameters, a movable and replaceable bending radius sleeve is provided at the lower part of the fixed vertical shaft to meet the needs of different bending radii of different bent pipes, and bending vertical poles with different spacings are provided above and below the bending cross bar to meet the needs of clamping and bending operations of bent pipes of different diameters. The adjustment is flexible, simple and practical, and meets the use requirements of different bending radii required for bending small diameter metal pipes (DN≤25mm) of different angles and different diameters used in the construction process of medium metal pipelines.

[0030] The utility model provides a bending device for small-diameter metal pipes. It does not need to replace different bending radius blocks to bend the bent pipes before installation. It can achieve rapid bending according to the required diameter and bending angle of the bent pipe by adjusting the size of the bending radius sleeve, adjusting the position of the baffle and adjusting the thickness of the gasket. The adjustment is flexible, simple and practical.
