[0042] The following is combined with Figure 1-8 This application is described in further detail.

[0043] The embodiment of the present application discloses a pipe cutting device. Figure 1The pipe cutting device includes a workbench 1, on which a power motor 2 is provided. The drive shaft of the power motor 2 is coaxially fixedly connected with a disc-shaped cutter 3. A clamping seat 4 is fixedly installed on the workbench 1. The length direction of the clamping seat 4 is in the same direction as the axial direction of the cutter 3. The clamping seat 4 is provided with a walking component 5 for driving the pipe to move along the axial direction of the cutter 3. The pipe in this embodiment is a metal hose. The side wall of the clamping seat 4 is provided with a limiting component 7 for preventing the pipe from deforming. The workbench 1 is provided with a height adjustment component 11 for driving the power motor 2 to rise and fall.

[0044] During cutting, the pipe is placed on the clamping seat 4, and the walking assembly 5 is used to drive the pipe to move along the axial direction of the cutter 3 until the part to be cut on the pipe moves below the cutter 3. The pipe is limited and fixed by the limiting assembly 7. At this time, the height adjustment assembly 11 can be used to drive the power motor 2 to move downward. While the power motor 2 moves downward, the power motor 2 drives the cutter 3 to rotate to achieve fixed-length cutting of the pipe. By limiting and fixing the pipe before cutting the pipe, it helps to avoid deformation of the cutter 3 when cutting the pipe, and the cutting effect is good, thereby improving the cutting efficiency of the pipe.

[0045] Reference Figure 1 In this embodiment, a loading assembly is provided on one side of the workbench 1, and the loading assembly is arranged on the side of the clamping seat 4 away from the cutter 3. The loading assembly is used to automatically transport the rolled pipe to the clamping seat 4, which saves time and effort and helps to improve the cutting efficiency of the pipe.

[0046] The loading assembly includes a bracket 20, a winding roller and a reduction motor 21. The bracket 20 is arranged on one side of the workbench 1. The winding roller is rotatably connected to the bracket 20. The axial direction of the winding roller is perpendicular to the traveling direction of the pipe. One end of the pipe is wound and connected to the winding roller, and the other end of the pipe extends to the clamping seat 4. The body of the reduction motor 21 is fixedly set on the bracket 20, and the drive shaft of the reduction motor 21 is coaxially fixedly connected to the winding roller; start the reduction motor 21, the reduction motor 21 drives the winding roller to rotate, and the winding roller unwinds the pipe, thereby realizing automatic loading of the pipe, replacing manual loading, saving time and effort, and helping to improve the cutting efficiency of the pipe.

[0047] Reference Figure 2 and Figure 3The walking assembly 5 includes a traveling motor 51 and a guide wheel 52. A clamping groove 53 is provided on the top surface of the clamping seat 4. The length direction of the clamping groove 53 is in the same direction as the axial direction of the cutter 3. The clamping groove 53 is used to accommodate the pipe. A cavity 54 is provided inside the clamping seat 4. The body of the traveling motor 51 is fixedly installed on the wall of the cavity 54. In this embodiment, the body of the traveling motor 51 can also be arranged on the outer wall of the clamping seat 4. The driving shaft of the traveling motor 51 is coaxially fixedly connected with the guide wheel 52. The groove wall of the clamping groove 53 opposite to its groove is provided with a guide opening 55. The clamping groove 53 is connected with the cavity 54 through the guide opening 55. The guide wheel 52 is vertically arranged, and part of the side wall of the guide wheel 52 passes through the guide opening 55 and extends into the clamping groove 53.

[0048] When the pipe is located within the clamping groove 53, the pipe wall abuts against the peripheral wall of the guide wheel 52. The travel motor 51 then drives the guide wheel 52 to rotate, generating friction between the guide wheel 52 and the pipe wall. This, in turn, causes the pipe to slide within the clamping groove 53 via the guide wheel 52, thereby moving the portion of the pipe to be cut below the cutter 3. In this embodiment, the number of revolutions of the guide wheel 52 driven by the travel motor 51 is controlled to control the length of the pipe movement, thereby achieving automatic, fixed-length cutting of the pipe, resulting in high cutting efficiency.

[0049] In order to further improve the stability of the conveying pipe, the clamping seat 4 is provided with an abutment 6 for abutting the pipe wall against the peripheral wall of the guide wheel 52, which helps to always abut the pipe against the peripheral wall of the guide wheel 52, and then as the guide wheel 52 rotates, the part of the pipe to be cut can be accurately conveyed to the bottom of the cutter 3, which helps to improve the cutting efficiency.

[0050] Reference Figure 3 The abutment 6 includes an adjusting cylinder 61 and a positioning wheel 62. A support plate 63 is provided on the workbench 1 and on both sides of the clamping seat 4. The support plate 63 is arranged in an L shape. The horizontal end of the support plate 63 is detachably mounted on the top surface of the workbench 1. A positioning block 64 is slidingly arranged between the opposite side walls of the two support plates 63. The adjusting cylinder 61 is arranged vertically, and the cylinder body of the adjusting cylinder 61 is fixedly mounted on the side wall of one of the support plates 63. The piston rod of the adjusting cylinder 61 is connected to the top surface of the positioning block 64, and the positioning wheel 62 is rotatably connected to the bottom wall of the positioning block 64. The positioning wheel 62 is located above the clamping seat 4, and the positioning wheel 62 and the guide wheel 52 are arranged relatively to each other up and down.

[0051] Start the adjusting cylinder 61, which drives the positioning block 64 to move down to a suitable height, so that a limiting space for positioning the pipe is formed between the positioning wheel 62 and the guide wheel 52; by abutting the peripheral wall of the positioning wheel 62 against the pipe wall, the peripheral wall of the guide wheel 52 is always abutted against the pipe wall of the pipe, which helps to avoid the generation of a gap between the pipe and the guide wheel 52, which may cause the pipe to be unable to move in the clamping groove 53.

[0052] Reference Figure 1 and Figure 4 The limit assembly 7 includes a limit seat 71, which is arranged on the side of the discharge end of the clamping seat 4.

The limit groove 76 communicates with the clamping groove 53 through the through hole 78. During the movement of the pipe in the clamping groove 53, the pipe passes through the through hole 78 and moves into the limit groove 76 until the cut portion of the pipe moves below the cutter 3, at which point the pipe is stopped from moving. The surface of the limit seat 71 is provided with a cutting groove 77 perpendicular to the limit groove 76. The cutting groove 77 is connected to the limit groove 76 and is used to allow the cutter 3 to move downward and cut the pipe groove.

The piston rod of the limit cylinder 73 is connected to the limit block 74. The limit block 74 is fixed with two limit rods 75 that are oppositely arranged and parallel to each other toward the side wall of the limit seat 71. The side wall of the limit seat 71 is provided with a limit hole 79 for the two limit rods 75 to be inserted into the limit groove 76.

[0055] When the piston rod of the limiting cylinder 73 extends, the limiting cylinder 73 drives the limiting block 74 to move toward the limiting seat 71, so that the two limiting rods 75 pass through the two limiting holes 79 and are inserted into the limiting groove 76, so that the pipe in the limiting groove 76 abuts against the groove wall of the limiting groove 76 adjacent to the groove opening, thereby achieving the positioning of the pipe. The cutter 3 is then driven downward, so that the cutter 3 moves down to between the two limiting rods 75 in the limiting groove 76. Then, as the cutter 3 rotates, the pipe is cut. In this embodiment, the two limiting rods 75 are used to limit and fix the pipe, minimizing deformation of the cutter 3 when cutting the pipe, which helps to improve the cutting effect and efficiency of the pipe.

[0057] In this embodiment, in order to improve the stability of the cutter 3 in cutting the pipe, a vertically arranged buffer tube 12 is fixed on the side wall of the lifting seat 111, and the bottom end of the buffer tube 12 is connected to the lifting block 113. A buffer spring is provided inside the buffer tube 12, and the two ends of the buffer spring are connected to the inner tube wall of the buffer tube 12. The expansion and contraction direction of the buffer spring is in the same direction as the expansion and contraction direction of the buffer tube 12; as the lifting block 113 rises and falls, the buffer tube 12 is compressed or stretched, and the buffer spring moves synchronously with the buffer tube 12, and then the good elastic force of the buffer spring is utilized to make the lifting block 113 rise and fall stably.

After the guide plate 176 moves down to a suitable height, the winding motor 178 is started, and the receipt motor drives the winding disc 19 to rotate, and then the winding disc 19 winds up the winding rope 179, and the baffle plate 177 is pulled toward The pipe is then lowered onto the receiving plate 16 by adjusting the height of the guide plate 176 and then lowering the pipe onto the receiving plate 16, thereby preventing the pipe from falling too high on the receiving plate 16 and causing the position of the free end of the pipe on the receiving plate 16 to change, so that the pipe can be tied, which helps to improve the efficiency of pipe cutting.

[0063] In this embodiment, rubber blocks can be provided along the circumference of the top edge of the receiving plate 16; the rubber blocks are used to limit the pipes on the receiving plate 16, which helps to prevent the pipes on the receiving plate 16 from rolling into the material receiving frame 13.

[0064] Reference Figure 7 and Figure 8 The tying assembly 22 includes a driving cylinder 221, a tying block 222, a plurality of pneumatic clamps 223, a plurality of tying belts 224, a plurality of tying cylinders 225 and a hot melt block 226 connected to the piston rod of the tying cylinder 225. The driving cylinder 221 is horizontally arranged on the side wall of the material receiving frame 13. The piston rod of the driving cylinder 221 is fixedly connected to the tying block 222. The length direction of the tying block 222 is in the same direction as the length direction of the cut pipe. A plurality of pneumatic clamps 223 are evenly distributed on the side wall of the tying block 222 and are arrayed along the length direction of the tying block 222.

[0065] In this embodiment, a number of binding straps 224 correspond one-to-one to a number of pneumatic clamps 223, and a number of binding straps 224 are arranged in an "inverted shape". The inner walls on both sides of the material receiving frame 13 are evenly distributed in an array along the vertical direction. The two free ends of the binding straps 224 correspond one-to-one to the inner walls on both sides of the material receiving frame 13, and the elastic clamps 227 are used to clamp the binding straps 224; the pipes on the receiving plate 16 guided by the guide plate 176 fall onto the horizontal side walls of the number of binding straps 224.

[0066] Several tying cylinders 225 correspond one to one with several pneumatic clamps 223 respectively. The cylinder body of the tying cylinder 225 is set on the side wall of the tying block 222 away from the pneumatic clamps 223. The piston rod of the tying cylinder 225 passes through the side wall of the tying block 222 and is connected to the hot melt block 226. A heating wire is provided in the hot melt block 226. When the heating wire is energized, the hot melt block 226 generates heat.

[0067] When the pipes on the plurality of binding bands 224 are stacked to a suitable height, the driving cylinder 221 is started, and the piston rod of the driving cylinder 221 is extended, so that the hot melt block 226 moves toward one of the free end side walls of the binding band 224, so that the pneumatic clamp 223 clamps one of the free end side walls of the binding band 224; then the driving cylinder 221 continues to drive the hot melt block 226 to move, so that the two free end side walls of the binding band 224 approach each other; until the distance between the two free end side walls of the binding band 224 reaches When it reaches the appropriate distance, the binding cylinder 225 is started, and the binding cylinder 225 drives the hot melt block 226 to move toward the two free end side walls of the binding belt 224, so that the two free end side walls of the binding belt 224 abut against each other, and by heating the hot melt block 226, the two free end side walls of the binding belt 224 are heated and melted under the high temperature of the hot melt block 226, and finally the automatic binding of the pipes stacked on the receiving plate 16 is realized to replace manual material collection and binding, saving time and effort, and helping to improve the efficiency of pipe cutting.

[0068] Reference Figure 6 A vertically arranged jack 161 is fixed to the bottom wall of the receiving frame 13, and the piston rod of the jack 161 is connected to the bottom surface of the receiving plate 16; after the pipes stacked on the receiving plate 16 are tied, the jack 161 is started to drive the receiving plate 16 to move upward so that personnel can take out the tied pipe stack.

[0069] In this embodiment, the side wall of the receiving plate 16 is provided with a clearance opening 162 for the clamp to pass through, so that when the receiving plate 16 moves upward, the clamp passes through the clearance opening 162, allowing the binding belt 224 to move upward stably.

[0070] The implementation principle of a pipe cutting device in an embodiment of the present application is: after placing the pipe in the clamping groove 53, start the adjusting cylinder 61 to move the positioning wheel 62 downward, and then the pipe is abutted between the opposite side walls of the positioning wheel 62 and the guide wheel 52 through the positioning wheel 62. At this time, the reduction motor 21 can be started, and the reduction motor 21 drives the guide wheel 52 to rotate, and then the guide wheel 52 provides the pipe with a feed force to move toward the cutter 3, so that the cutting point of the pipe is moved below the cutter 3, and at the same time, the free end of the pipe passes through the through hole 78 and moves into the limit groove 76.

[0071] The limiting cylinder 73 is then activated, and its piston rod extends, causing the two limiting rods 75 to pass through the two limiting holes 79, respectively. The two limiting rods 75 then abut the pipe against the wall of the limiting groove 76. At this point, the lifting cylinder 112 is activated, driving the lifting block 113 downward within the lifting groove 114, causing the power motor 2 to move downward, and the cutter 3 to move downward synchronously with the power motor 2. As the power motor 2 moves downward, the power motor 2 drives the cutter 3 to rotate, thereby achieving a fixed-length cut of the pipe. The two limiting rods 75 secure the pipe, helping to prevent deformation of the pipe when the cutter 3 cuts it, thereby improving the cutting effect and efficiency of the pipe.

[0072] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
