At the same time, it also brings many inconveniences and bad effects to users. In addition, when processing metal pipe joints, there are several processes.

DETAILED DESCRIPTION

[0019] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings to make the technical solutions and beneficial effects of the present invention clearer and more specific.

[0020] See attached Figures 1 to 5 The present invention comprises a frame 1 and a controller 2 for controlling the whole machine, and is characterized in that: the frame 1 is provided with a taper pipe cutting device 3 and a thread rolling device 4 located on the same working axis, and both the taper pipe cutting device 3 and the thread rolling device 4 are provided with a driving wheel 5 and a pipe clamping assembly 6, and the driving wheel 5 is connected to a stepping motor 8 electrically connected to the controller 2 through a gear box 7; the driving wheel 5 is provided with a plurality of stepping assemblies 9 arranged equidistantly with the center of the driving wheel 5 as the center point, and the stepping assembly 9 includes a stepping gear 901 An active screw rod 902 is connected below the stepping gear 901, a slider 903 is provided on the active screw rod 902, and an auxiliary part 904 corresponding to the center of the circle of the active wheel 5 is provided on the slider 903; it also includes a toggle part 905 matched with the stepping gear 901; the auxiliary part 904 on the thread rolling device 4 is connected to the thread rolling wheel 10; the auxiliary part 904 on the taper pipe cutting device 3 is connected to an equal number of pipe cutting tools 11 and taper rollers 12, and the pipe cutting tools 11 and the taper rollers 12 are arranged at intervals.

[0021] Furthermore, the taper roller 12 is conical.

[0022] Furthermore, the rolling wheel 10 is conical, and the circumferential surface of the rolling wheel 10 is provided with lines for pressing threads on the pipe.

[0023] Furthermore, the stepping gear 901 corresponding to the tube cutting tool 11 and the stepping gear 901 corresponding to the taper roller 12 are not at the same height, and the shifting member 905 matched with the stepping gear 901 is positionally adjustable.

[0024] Furthermore, the tube clamping assembly 6 includes a ring-shaped tube clamping gear 601 and a plurality of support members 602 meshing with the tube clamping gear 601, and the support members 602 can move inward or outward simultaneously with the rotation of the tube clamping gear 601; the tube clamping gear 601 is connected to a stepper motor 2 604 electrically connected to the controller 2 through a gear box 2 603.

[0025] Furthermore, a pipe pressing member 605 is provided on the inner side of the support member 602 , and a pressure sensor 606 for measuring the squeezing force between the pipe pressing member 605 and the pipe is provided between the pipe pressing member 605 and the support member 602 , and the pressure sensor 606 is electrically connected to the controller 2 .

[0026] Furthermore, the stepping gear 901 is provided with a hexagonal hole 906 for adjustment.

[0027] Furthermore, a cooling nozzle 13 for cooling the processing part is provided above the stepping assembly 9 .

[0028] Select the corresponding rolling wheel 10, pipe cutting tool 11, taper roller 12 according to the pipe material, or adjust the parameters of the taper pipe cutting device 3 and rolling device 4 according to the pipe material. During processing, select the processing procedures according to the needs; usually the first procedure is to repair the taper of the pipe end, adjust the toggle member 905 to the taper repair position, insert the pipe into the appropriate position in the taper pipe cutting device 3, and start the pipe clamping assembly 6 through the controller 2 to clamp the pipe. When the controller 2 receives the pressure sensor 606 on the pipe clamping assembly 6 and senses that the clamping force reaches the preset force, it turns off the power of the stepper motor 2 604 on the pipe clamping assembly 6 in the taper pipe cutting device 3; then start the stepper motor 1 8 on the taper pipe cutting device 3, and the stepper motor 1 8 is driven by the gear box 1 7 drives the driving wheel 5 to rotate, and the stepping gear 901 of the taper-fixing stepping assembly 9 on the driving wheel 5 moves one tooth each time it passes through the toggle member 905; the stepping gear 901 drives the driving screw 902 to rotate, and the driving screw 902 moves the slider 903 downward, and the slider 903 pushes the taper-fixing roller 12 downward through the auxiliary member 904, and the taper-fixing roller 12 gradually applies pressure to the pipe to press the end of the pipe into a taper that is convenient for connection with the connector; after the taper is fixed, the taper-fixing pipe cutting device 3 rotates in the opposite direction to return to its original position, and then the inner pipe clamping assembly 6 rotates to release the clamping of the pipe.

[0029] The pipe cutting process is basically the same as the taper trimming process, and the only thing to do is to adjust the toggle member 905 to a position corresponding to the pipe cutting. When the driving wheel 5 rotates, the stepping gear 901 corresponding to the pipe cutting tool 11 contacts the toggle member 905 .

[0030] When performing the thread rolling process, its working principle is similar to that of taper trimming and pipe cutting, except that the thread rolling device 4 is turned on, the pipe with the tapered shape is inserted into the thread rolling device 4, the pipe clamping assembly 6 clamps the pipe, and the thread rolling wheel 10 on the thread rolling device 4 rolls the end of the pipe with the tapered shape.

[0031] The end of the pipe is tapered and rolled by extrusion, which will not damage the anti-rust layer on the surface of the pipe and can maintain an optimal pipe wall thickness, making the pipe easier to install and more durable.

[0032] Through the description of the above structure and principle, technicians in the relevant technical field should understand that the present invention is not limited to the above-mentioned specific implementation methods. Improvements and substitutions based on the present invention using the well-known technology in the field all fall within the protection scope of the present invention and should be defined by the claims.
