[0017] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the utility model provides an electric pipe cutting device, comprising a horizontally arranged bottom plate 1, a vertically arranged support frame 2 is fixed on the top surface of the bottom plate 1, a vertically arranged hydraulic cylinder 21 is fixed on the support frame 2, a horizontally arranged first motor 22 is fixed on the output end of the hydraulic cylinder 21, and a vertically arranged cutting blade 23 is fixed on the output end of the first motor 22; a vertically arranged fixing frame 3 is fixed on the top surface of the bottom plate 1, a horizontally arranged fixing rod 31 is fixed on the fixing frame 3, two symmetrical clamping strips 4 are hinged on the fixing rod 31, the parts of the two clamping strips 4 located below the fixing rod 31 are in an arc-shaped structure, and the arc-shaped concave surfaces of the two clamping strips 4 are arranged oppositely, and the clamping surfaces of the two clamping strips 4 are parallel to the cutting blade 23, The fixed frame 3 is provided with a first driving component for driving the two clamping strips 4 to rotate around the hinge; a vertical limit plate 5 is movably provided on the top surface of the base plate 1, the support frame 2 is located between the fixed frame 3 and the limit plate 5, and a cylinder 51 for driving the limit plate 5 to move closer to or away from the support frame 2 is fixed on the base plate 1; a horizontally arranged base 7 is fixed on the top surface of the base plate 1, the fixed frame 3 is located between the support frame 2 and the base 7, a horizontally arranged U-shaped plate 71 is fixed on the top surface of the base 7, and a transport component for transporting power pipes is provided on the U-shaped plate 71; the projections of the centers of the support frame 2, the fixed frame 3, the U-shaped plate 71 and the limit plate 5 in the vertical direction are all located on a straight line, and the power pipe can pass through the middle of the support frame 2 and the fixed frame 3.

[0019] like Figure 4 As shown, the first driving assembly includes an automatic push rod 41 vertically fixed to the inner top surface of the fixing frame 3, and a horizontal first connecting rod 42 is fixed to the output end of the automatic push rod 41. The two ends of the first connecting rod 42 are respectively rotatably connected to a second connecting rod 43 whose one end is rotatably connected to the top of the clamping strip 4; the portion of the fixing rod 31 located between the two clamping strips 4 is an arc-shaped structure, and the arc-shaped convex surface is arranged toward the first connecting rod 42. When the automatic push rod 41 is started, the output end of the automatic push rod 41 pushes the first connecting rod 42 to move up and down, thereby driving the top of the clamping strip 4 to rotate around the hinge through the second connecting rod 43. In this way, the arc-shaped portions of the two clamping strips 4 can be rotated around the hinge by using the lever principle, thereby achieving the fixation of power pipes of different sizes.

[0020] like Figure 1 , Figure 2 and Figure 6As shown, two vertical support plates 8 are fixed to the top surface of the bottom plate 1, which are respectively located on both sides of the base 7. The conveying assembly includes two electric push rods 81 horizontally fixed to opposite sides of the support plates 8. The output ends of the two electric push rods 81 are fixed with horizontally arranged fixed blocks 82, and the top surface of the fixed blocks 82 is fixed with a vertically arranged third motor 83. The output end of the third motor 83 is fixed with a horizontally arranged rotating wheel 84. Openings 72 are provided on both sides of the U-shaped plate 71 for the movement of the fixed blocks 82, the third motor 83 and the rotating wheels 84. After placing the electric pipe horizontally on the inner side of the U-shaped plate 71, start the electric push rod 81, and drive the rotating wheel 84 to move in the horizontal direction through the fixed block 82, so that the rotating wheel 84 contacts the outer wall of the electric pipe. Then, start the third motor 83, and the output end of the third motor 83 drives the rotating wheel 84 to rotate, so that the electric pipe is driven to move through the rolling friction between the rotating wheel 84 and the electric pipe, so as to realize the control of the cutting length of the electric pipe; in addition, when the cutting blade 23 cuts the electric pipe, the rotating wheel 84 is separated from the electric pipe through the electric push rod 81, thereby avoiding the vibration generated when cutting the steel pipe from acting on the rotating wheel 84, thereby achieving the effect of increasing the service life of the rotating wheel 84.

[0021] like Figure 1 and Figure 3 As shown, horizontally arranged support rods 25 are respectively fixed on both sides of the first motor 22, sliders 26 are fixed on the opposite ends of the two support rods 25, and side grooves 27 corresponding to the sliders 26 are provided on both sides of the support frame 2. The arrangement of the support rods 25, the sliders 26 and the side grooves 27 can not only play a good role in limiting and guiding the movement of the first motor 22, but also provide strong support for the first motor 22 and the cutting blade 23.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, the two sides of the side of the limit plate 5 facing away from the cylinder 51 are respectively fixed with vertically arranged limit blocks 6, and two symmetrical clamping blocks 61 are movably arranged between the two limit blocks 6. The opposite sides of the two clamping blocks 61 are in arc shape, and the limit block 6 is provided with a second driving component for driving the two clamping blocks 61 to move closer to or away from each other. When one end of the power tube contacts the side of the limit plate 5 facing away from the cylinder 51, the power tube will be just located between the arc-shaped surfaces of the two clamping blocks 61, and the second driving component is used to make the two clamping blocks 61 approach each other, and make the outer surface of the power tube close to the arc-shaped surfaces of the two clamping blocks 61, so as to achieve the fixation of the cut end of the power tube, and effectively prevent the problem of uneven cutting caused by shaking of the power tube when it is cut.

[0023] like Figure 2 and Figure 5As shown, the second driving assembly includes a second motor 63 fixed inside the limit block 6, and a bidirectional screw rod 62 located between the two limit blocks 6 and in a horizontal position is fixed at the output end of the second motor 63, and the bidirectional screw rod 62 is threadedly connected to the bottom end of the clamping block 61. When the second motor 63 is started, the output end of the second motor 63 drives the bidirectional screw rod 62 to rotate, so that the two clamping blocks 61 can be moved closer to or farther from each other, thereby fixing the cut end of the power pipe.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, the bottom of the two limit blocks 6 are fixed with a horizontally arranged guide block 64, the bottom plate 1 is provided with a slide groove 11 corresponding to the guide block 64, the outside of the cutting blade 23 is fixed with a protective cover 24, and the length of the slide groove 11 is equal to the linear distance from the clamping block 61 to the projection of the protective cover 24 on the horizontal plane. The setting of the guide block 64 and the slide groove 11 can play a good role in limiting and guiding the movement of the limit block 6 in the horizontal direction; and the length of the slide groove 11 is equal to the linear distance from the clamping block 61 to the projection of the protective cover 24 on the horizontal plane, so that the clamping block 61 will not affect the movement of the cutting blade 23.

[0025] like Figure 4 As shown, a rubber layer 44 is fixed on the opposite side of the two clamping strips 4. The provision of the rubber layer 44 can not only prevent the surface of the power tube from being accidentally scratched when the two clamping strips 4 clamp the power tube, but also increase the friction between the power tube and the clamping strips 4, thereby effectively fixing the power tube.

[0026] like Figure 1 As shown, a support 9 is fixed to the bottom of the base plate 1. The support 9 can support the entire device.

[0027] When in use, after the power tube is placed horizontally on the inner side of the U-shaped plate 71, the electric push rod 81 is started, and the rotating wheel 84 is driven to move in the horizontal direction through the fixed block 82, so that the rotating wheel 84 contacts the outer wall of the power tube. Then, the third motor 83 is started, and the output end of the third motor 83 drives the rotating wheel 84 to rotate, thereby driving the power tube to move toward the limit plate 5 through the rolling friction between the rotating wheel 84 and the power tube. Since the projections of the centers of the support frame 2, the fixed frame 3, the U-shaped plate 71 and the limit plate 5 in the vertical direction are all located in a straight line, the power tube can pass through the fixed frame 3 and the support frame 2 in turn, and one end of the power tube can contact the side of the limit plate 5 facing away from the cylinder 51; at this time, the power tube will be just located between the arc-shaped surfaces of the two clamping blocks 61, and the cylinder 51 is started to drive the limit plate 5 to move closer to or away from the support frame 2, so as to adjust the power tube. The cutting length of the power tube is determined by adjusting the power tube to a suitable position, and then the second motor 63 is started. The output end of the second motor 63 drives the bidirectional screw 62 to rotate, so that the two clamping blocks 61 can be brought close to each other, and the outer surface of the power tube is tightly attached to the arc-shaped surfaces of the two clamping blocks 61, thereby fixing the cut end of the power tube; at the same time, the automatic push rod 41 is started, and the output end of the automatic push rod 41 pushes the first connecting rod 42 to move up and down, thereby driving the top end of the clamping strip 4 to rotate around the hinge through the second connecting rod 43. In this way, the arc-shaped parts of the two clamping strips 4 can be rotated around the hinge by utilizing the lever principle, and the opposite sides of the two clamping strips 4 can be in contact with the outer wall of the power tube, thereby fixing power tubes of different sizes; finally, the hydraulic cylinder 21 and the first motor 22 are started, so that the cutting blade 23 moves down and rotates, thereby realizing the cutting operation of the power tube.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
