These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0037] As mentioned in the background technology, waterjet cutting technology, as a non-thermal processing method, has been widely used in many industries such as metal, stone, and composite materials. Its basic principle is to use high-pressure water flow (or high-pressure water flow with added abrasive) to cut various materials. Compared with traditional mechanical cutting and laser cutting, waterjet cutting has the advantages of wide cutting range, no heat-affected zone, and no cutting force damage.

[0038] However, it is often difficult to ensure high-precision cutting during the cutting process of existing water jet cutting equipment. Due to the impact of the water flow and the movement of the pipe, the cutting line is likely to deviate from the predetermined trajectory, resulting in errors and affecting the cutting quality.

[0039] According to the above relevant description, the pipe cutting device provided in the embodiment of the present application measures the length of the pipe cut by the cutting member by setting a distance measuring member, and at least two clamping members are arranged on two opposite sides of the cutting member. The distance measuring member can measure the length of the pipe, reduce the error of pipe cutting, ensure the cutting accuracy, and thus prevent material waste caused by pipe cutting deviation.

[0040] In addition, after the clamping piece fixes the pipe, it can prevent the cutting piece from shifting or vibrating due to external forces during the cutting process. At least two clamping pieces placed on both sides of the cutting piece can fully fix the pipe, so that the cutting piece is always on the vertical cutting plane during the entire cutting process of the pipe, thereby ensuring cutting accuracy.

[0041] The pipe cutting device according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, one or more embodiments of the present application provide a pipe cutting device, including a main platform 100 , a cutting member 200 , a distance measuring member 300 and at least two clamping members 400 .

[0043] The main platform 100 has a cavity 105 for accommodating the pipe;

[0044] The cutting piece 200 is arranged on the main platform 100, and the cutting piece 200 is used to cut the pipe along the radial direction of the pipe; the distance measuring piece 300 is installed on the main platform 100, and is configured to measure the length of the pipe cut by the cutting piece 200; at least two clamping pieces 400 are arranged inside the cavity 105, and at least two clamping pieces 400 are respectively located on two opposite sides of the cutting piece 200, and the clamping piece 400 has a fixed state for clamping the pipe, and an unlocked state for releasing the constraint on the pipe.

[0045] It can be seen from the above description that the pipe cutting device of the embodiment of the present application measures the length of the pipe cut by the cutting member 200 by setting a distance measuring member 300, and at least two clamping members 400 are arranged on opposite sides of the cutting member 200. The distance measuring member 300 can measure the length of the pipe, reduce the error of pipe cutting, ensure the cutting accuracy, and thus prevent material waste caused by pipe cutting deviation.

[0046] In addition, after the clamping member 400 fixes the pipe, it can prevent the cutting member 200 from shifting or vibrating due to external forces during the cutting process. At least two clamping members 400 disposed on both sides of the cutting member 200 can fully fix the pipe, so that the cutting member 200 is always on the vertical cutting plane during the entire cutting process of the pipe, thereby ensuring cutting accuracy.

[0047] In the embodiment of the present application, the cutting element 200 is a nozzle for emitting high-pressure liquid, and the nozzle can adopt a water cutting equipment nozzle assembly in the related art.

[0048] Generally, a nozzle is usually composed of a tiny hole, which can be very small, usually between 0.1 and 0.5 mm. The nozzle is designed to focus the high-pressure water flow into an extremely fine jet, thereby generating enough energy to cut the material.

[0049] The nozzle in the above embodiment can be made of tungsten carbide, sapphire or diamond material, and the nozzle can be set to one or more. When multiple nozzles are set, the multiple nozzles are arranged in parallel along a direction perpendicular to the extension direction of the pipe to facilitate cutting of the pipe.

[0050] In the embodiment of the present application, the distance measuring part 300 can be a laser distance meter or a meter. During the transportation of the pipe, the distance measuring part 300 records each stop position of the pipe, and obtains the transportation length of the pipe according to two adjacent stop positions, thereby determining the actual cutting position of the pipe. Here, the setting of the distance measuring part 300 can further improve the positioning accuracy of the pipe and prevent deviation in cutting during the transportation of the pipe.

[0051] In addition, the pipes mentioned in the embodiments of the present application may be plastic pipes, or other materials such as ceramic materials or stone pipes.

[0052] like Figure 1 As shown, Figure 1 The direction of the middle arrow is the extension direction of the pipe. The pipe transported by external force enters the cavity 105 of the main platform 100 along the extension direction. After being cut by the cutting piece 200, the pipe located at the front end of the arrow direction is removed, and the pipe located at the rear end of the arrow direction continues to be pushed into the cavity 105 by external force, and the cutting operation is repeated.

[0053] In some embodiments, the pipe cutting device further includes a guide rail 500 and a driving member.

[0054] The guide rail 500 is fixed on the main platform 100, and the cutting member 200 is slidably arranged on the guide rail 500; the driving member is connected to the cutting member 200 to drive the cutting member 200 to perform periodic reciprocating displacement on the guide rail 500, and the displacement direction of the cutting member 200 on the guide rail 500 is perpendicular to the extension direction of the pipe.

[0055] In the above embodiment, the guide rail 500 can be fixed on the main platform 100 by bolting or welding. Here, for example, the cutting piece 200 is installed on a slider, and the slider slides smoothly on the guide rail 500 to drive the displacement of the cutting piece 200 on the guide rail 500.

[0056] The sliding connection between the slider and the guide rail 500 can be flexibly designed according to different operating scenarios. For example, the slider and the guide rail 500 are connected by a lead screw, or the motor is a linear drive motor, and the output end of the motor is fixedly connected to the slider to drive the slider to move on the guide rail 500.

[0057] It should be noted that in order to avoid interference of the cutting piece 200 by the guide rail 500 when the cutting piece 200 slides on the guide rail 500, the upper end surface of the cutting piece 200 is slidably connected to the guide rail 500, and the nozzle part of the cutting piece 200 is located at the lower part of the cutting piece 200, and the nozzle part of the cutting piece 200 extends into the cavity 105 for water cutting operation.

[0058] Since the displacement direction of the cutting member 200 on the guide rail 500 is perpendicular to the extension direction of the pipe, the cutting error of the cutting member 200 during the cutting process can be reduced during the reciprocating displacement of the cutting member 200 on the guide rail 500, thereby improving the cutting accuracy; in addition, the reciprocating displacement of the cutting member 200 can ensure that the pipe is subjected to uniform force during the cutting process, thereby making the cut section of the pipe smoother. In addition, the driving member is connected to the cutting member 200, so that an automated reciprocating cutting operation and a continuous cutting operation can be realized, thereby reducing manual intervention and improving work efficiency.

[0059] In some embodiments, by adjusting the output power of the driving member, the displacement speed of the cutting member 200 on the guide rail 500 can be adjusted. For example, when the displacement speed of the cutting member 200 is slow, the cutting member 200 has enough time to cut the pipe, so it is suitable for the operation of thick pipes. When the displacement speed of the cutting member 200 is fast, it can cut thin pipes while improving the cutting efficiency and saving time. Therefore, by adjusting the displacement speed of the cutting member 200 on the guide rail 500, it can better adapt to the cutting operation of pipes with different wall thicknesses.

[0060] like Figure 2 As shown, the pipe cutting device of the embodiment of the present application further includes a liquid storage box 600, a pressure regulating component 700 and an energy storage component 800.

[0061] The liquid storage tank 600 is connected to the cutting piece 200 through an infusion pipeline to transport coolant to the cutting piece 200. A filter is provided at the output port of the liquid storage tank 600. The pressure regulating component 700 is provided on the infusion pipeline to regulate the hydraulic pressure of the infusion pipeline. The energy storage component 800 is respectively connected to the infusion pipeline and the cutting piece 200, and is configured to balance the hydraulic pressure of the infusion pipeline.

[0062] In the above-mentioned embodiment, the coolant may be water. Of course, in some embodiments, in order to enhance the cutting strength, the coolant may be mixed with abrasives, such as garnet sand, etc., which is not absolutely limited in the embodiments of the present application.

[0063] A filter is provided at the output port of the liquid storage tank 600 to filter out larger impurities to prevent the impurities from blocking the cutting element 200 and affecting the cutting operation. Here, the filter mesh number should be set according to the coolant. When the coolant is mixed with abrasives, the filter can allow the abrasives to pass through and block other large impurities.

[0064] The above-mentioned pressure regulating component 700 can adopt a booster in the related technology. The pressure regulating component 700 can increase the hydraulic pressure of the coolant to the pressure required for cutting. Usually, the cutting hydraulic pressure range of the cutting piece 200 is 30,000 to 60,000 psi (about 200 to 400 MPa). The coolant pressurized by the pressure regulating component 700 is sprayed out through the cutting piece 200 to cut the pipe.

[0065] The energy storage component 800 can be an accumulator in the related art. The function of the accumulator is to buffer the pressure fluctuation in the infusion pipeline and provide a stable, constant pressure high-pressure liquid flow. Since the hydraulic pressure fluctuation adjusted by the pressure adjustment component 700 easily affects the cutting quality, the energy storage component 800 can be provided to stabilize the cutting water pressure output of the cutting element 200, thereby making the cut section of the pipe smooth and neat.

[0066] like Figure 1As shown, in some embodiments, a confluence port 101 communicating with the outside is disposed at the bottom of the main platform 100 , and the confluence port 101 is communicated with the cavity 105 to discharge the cooling liquid out of the cavity 105 through the confluence port 101 .

[0067] Since the cutting piece 200 generates debris during the process of cutting the pipe, the debris mixed with the coolant will easily block the confluence 101. Therefore, a filter can be set on the confluence 101 to filter the debris, and the confluence 101 can be prevented from being blocked by regularly cleaning the filter.

[0068] By providing the confluence port 101 on the main platform 100 , the coolant sprayed out by the cutting member 200 can be discharged from the main platform 100 through the confluence port 101 , thereby preventing the coolant in the main platform 100 from accumulating and overflowing.

[0069] In some embodiments, the main platform 100 includes a shell 103 and a cover 104 detachably connected to the shell 103 . The shell 103 and the cover 104 together form a cavity 105 , and the cutting member 200 is disposed on the cover 104 .

[0070] In the above embodiment, the shell 103 and the cover 104 are rotatably connected via a rotating shaft passing through the two, or the shell 103 and the cover 104 are connected via a fastener passing through both, as long as the shell 103 and the cover 104 are detachably connected.

[0071] Since the shell 103 and the cover 104 are detachably connected, when the cover 104 is removed, it is convenient for operators to inspect and maintain the relevant components inside the shell 103, such as the clamping member 400 and the guide member, thereby helping to extend the service life of the pipe cutting device.

[0072] In some embodiments, the cutting piece 200 is disposed on the cover body 104, and the clamping piece 400 is disposed on the side wall of the shell 103. When the pipe extends into the cavity 105 of the main platform 100, the above design can avoid interference between the cutting piece 200 and the clamping piece 400, thereby ensuring the normal progress of the pipe cutting operation.

[0073] Furthermore, a support frame 102 is provided at the bottom of the shell 103, and the height of the support frame 102 is adjustable. Here, the height adjustment method of the support frame 102 can be flexibly set, for example, the height of the support frame 102 can be changed by driving a hydraulic drive or a linear drive motor.

[0074] By setting up the support frame 102, the height of the shell 103 can adapt to the position of pipes of different diameters. When the pipe is horizontally transported to the inlet end of the shell 103, the height of the shell 103 is adjusted to ensure that the inner cavity 105 of the main platform 100 is at the same level as the pipe, preventing the pipe from tilting and affecting the cutting accuracy.

[0075] In some embodiments, the lower end surface of the shell 103 for contacting the pipe is provided with at least two guides, which are arranged at intervals along the conveying direction of the pipe, and are used to guide the pipe to pass through the main platform 100 .

[0076] The guide member in the above embodiment is a roller or a roller member. After the tube enters the cavity 105, it is supported by the guide member and guided by the guide member to pass through the cavity 105. Providing the guide member can enhance the sliding property of the tube in the cavity 105, so that the tube can pass through the cavity 105 smoothly.

[0077] In addition, in some embodiments, the inner wall of the main platform 100 is provided with a noise reduction layer, and the noise reduction layer can be made of a material that can isolate noise, such as foam, sponge, etc. The provision of the noise reduction layer can reduce the cutting noise generated in the main platform 100 as much as possible.

[0078] like Figure 3 As shown, in some embodiments, the clamping member 400 includes two hingedly connected jaws 401. When driven by an external force, the two jaws 401 move toward each other to clamp the pipe. An elastic buffer layer is provided on the abutting surface of the jaws 401 for clamping the pipe.

[0079] The clamping member 400 in the above embodiment can be a pneumatic clamping jaw 401 or a hydraulic clamping jaw 401. The clamping member 400 is controlled by a motor or hydraulic pressure to perform a clamping or opening action. Figure 1 It can be seen that the clamping member 400 is arranged on the side wall surface of the shell 103. This arrangement can avoid interference between the clamping member 400 and the guide member or the cutting member 200, while being able to flexibly switch between a fixed state and an unlocked state.

[0080] In some embodiments, the elastic buffer layer can be made of foam or rubber material, and the elastic buffer layer is bonded to the clamping jaw 401. The provision of the elastic buffer layer can prevent the clamping jaw 401 from clamping and damaging the pipe when clamping the pipe.

[0081] In some embodiments, when the pipe enters the cavity 105 of the main platform 100, the pipe is actually located between the two clamping jaws 401 of the clamping member 400, so that the clamping jaws 401 can clamp the pipe. Of course, it can also be designed that the clamping jaws 401 can move along the radial direction of the main platform 100 to approach the pipe and then clamp the pipe, which is not absolutely limited in the embodiments of the present application. In order to avoid excessive wear of the clamping jaws 401 by the pipe, the clamping jaws 401 are configured to first approach the pipe in the radial direction and then clamp the pipe.

[0082] It should be noted that, in some embodiments, the pipe cutting device also includes a control component 900, and the control component 900 is respectively connected to the cutting member 200, the clamping member 400, and the pressure regulating member 700 to control the operating status of the above-mentioned related components. Here, the control component 900 can refer to the design in the relevant technology for regulating the above-mentioned related components, for example, by programming the PLC circuit control.

[0083] An exemplary operation process of the pipe cutting device in the embodiment of the present application is as follows:

[0084] The pipe is transported into the cavity 105 of the main platform 100 by external force. When the pipe measured by the distance measuring component 300 reaches the required length, the control component 900 adjusts the clamping jaws 401 of the clamping component 400 to clamp the pipe towards each other, so that the pipe is in a fixed state. Then, the control component 900 controls the pressure regulating component 700 to increase the pressure, so that the coolant in the liquid storage tank 600 is sprayed out through the cutting component 200 under the action of pressure, and the pipe is cut. During the cutting operation, the cutting component 200 moves along the guide rail 500 to cut.

[0085] After the cutting is completed, the control component 900 adjusts the clamping claw 401 of the clamping member 400 to release the pipe, and the pipe resumes the free displacement state. Under the action of external force, the front end of the pipe is removed and stored, and the rear end of the pipe continues to extend into the cavity 105 to repeat the above-mentioned cutting operation.
