Description

Technical Field

[0001] This application belongs to the field of pipe cutting technology, and more specifically, relates to a pipe cutting method, apparatus, storage medium and computer equipment. Background Technology

[0002] Currently, pipe cutting typically involves first using a feeding device to transport the pipe to the cutting station, where a cutting head then cuts the pipe. The pipe needs to be stopped from being fed during the cutting process, and feeding resumes only after the cutting is complete, resulting in low processing efficiency. Summary of the Invention

[0003] This application provides a pipe cutting method in which feeding and cutting are carried out simultaneously, thereby improving processing efficiency.

[0004] The technical solution adopted in this application embodiment is: to provide a pipe cutting method for sequentially cutting workpieces along preset cutting points on a pipe, wherein one workpiece is cut from each preset cutting point; including:

[0005] The pipe conveying mechanism drives the pipe to move along a first direction to convey the pipe;

[0006] The rotary cutting mechanism moves a first preset distance along the first direction to cut the workpiece along the current preset cutting point;

[0007] The rotary cutting mechanism moves a second preset distance along a second direction to the starting position of the next preset cutting point. The second direction is opposite to the first direction, and the first preset distance is equal to the second preset distance.

[0008] The starting positions of the rotary cutting mechanism when it moves to two adjacent or more preset cutting points are compared to obtain the position deviation value. If the position deviation value exceeds the preset range, the feeding speed of the pipe conveying mechanism is adjusted.

[0009] Furthermore, the step "comparing the starting positions of the rotary cutting mechanism to two adjacent or spaced-apart preset cutting points to obtain a position deviation value, and if the position deviation value exceeds a preset range, adjusting the feeding speed of the pipe conveying mechanism" specifically includes:

[0010] Obtain the starting position a, where n≥1, of the rotary cutting mechanism moving to the nth preset cutting point;

[0011] Obtain the starting position b of the rotary cutting mechanism when it moves to the (n+m)th preset cutting point, where m≥1;

[0012] If the first preset value < ab < the second preset value, then determine whether a is greater than b;

[0013] If a > b, the feeding speed of the pipe conveying mechanism increases according to the first preset adjustment coefficient.

[0014] If a < b, the feeding speed of the pipe conveying mechanism is reduced according to the second preset adjustment coefficient.

[0015] Furthermore, the first preset adjustment coefficient is 5% to 15%, and the second preset adjustment coefficient is 5% to 15%.

[0016] Furthermore, the first preset value is -30 to -5 mm, and the second preset value is 5 to 30 mm.

[0017] Furthermore, the step "comparing the starting positions of the rotary cutting mechanism to two adjacent or spaced-apart preset cutting points to obtain a position deviation value, and adjusting the feeding speed of the pipe conveying mechanism if the position deviation value exceeds a preset range" also includes:

[0018] If ab ≤ the first preset value, or ab ≥ the second preset value, then the feeding speed of the pipe conveying mechanism will not be adjusted.

[0019] Furthermore, the rotary cutting mechanism rotates in opposite directions when cutting two adjacent preset cutting points.

[0020] Furthermore, before the step "the rotary cutting mechanism moves a first preset distance along the first direction to cut the workpiece along the current preset cutting point", the method further includes:

[0021] The speed at which the rotary cutting mechanism moves along the first direction is coupled with the feeding speed of the pipe conveying mechanism, such that the speed at which the rotary cutting mechanism moves along the first direction satisfies the following formula:

[0022] V 切割 =V 管 +△V;

[0023] The feeding speed of the pipe conveying mechanism is defined as V. 管 The rotary cutting mechanism moves at a speed of V along the first direction. 切割 The preset speed is ΔV.

[0024] Furthermore, the step "comparing the starting positions of the rotary cutting mechanism to two adjacent or spaced-apart preset cutting points to obtain a position deviation value, and if the position deviation value exceeds a preset range, adjusting the feeding speed of the pipe conveying mechanism" further includes:

[0025] The pipe conveying mechanism drives the pipe to move along the first direction at an adjusted feeding speed.

[0026] This application also provides a pipe cutting device, including:

[0027] A pipe conveying mechanism is used to drive the pipe to move along a first direction to convey the pipe;

[0028] A rotary cutting mechanism moves a first preset distance along a first direction to cut the workpiece at a current preset cutting point. The rotary cutting mechanism also moves a second preset distance along a second direction to the starting point of the next preset cutting point. The second direction is opposite to the first direction, and the first preset distance and the second preset distance are equal.

[0029] The position comparison module is used to compare the starting positions of the rotary cutting mechanism when it moves to two adjacent or more preset cutting points, and obtain the position deviation value. If the position deviation value exceeds the preset range, the feeding speed of the pipe conveying mechanism is adjusted.

[0030] This application also provides a computer device, including:

[0031] A processor is configured to execute computer-executable instructions;

[0032] The memory stores one or more computer-executable instructions that, when executed by the processor, implement the various steps of the pipe cutting method as described above.

[0033] This application also provides a computer-readable storage medium having a computer program stored thereon, the computer program being executed by a processor to implement the various steps of the pipe cutting method described above.

[0034] The beneficial effects of the pipe cutting method provided in this application embodiment are as follows: In the pipe cutting method of this application embodiment, the pipe conveying mechanism drives the pipe to move along the first direction to convey the pipe, the rotary cutting mechanism moves along the first direction by a first preset distance to cut the workpiece along the current preset cutting point, and the rotary cutting mechanism moves along the second direction by a second preset distance to move to the starting point position of the next preset cutting point. The second direction is opposite to the first direction, and the first preset distance is equal to the second preset distance, so that each preset cutting point can be tracked and cut sequentially, realizing the synchronous operation of feeding and cutting, and improving work efficiency. Moreover, by comparing the starting point positions of the rotary cutting mechanism to two adjacent or more preset cutting points, a position deviation value is obtained. If the position deviation value exceeds the preset range, the feeding speed of the pipe conveying mechanism is adjusted. Thus, by comparing the position deviation value of the rotary cutting mechanism at the starting point positions of two adjacent or more preset cutting points, the feeding speed of the pipe conveying mechanism can be adjusted in real time, avoiding the rotary cutting mechanism from moving beyond the stroke range along the first direction due to the feeding speed of the pipe conveying mechanism being too fast or too slow during the actual cutting process, ensuring the effective cutting.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0046] Please see Figure 1 and Figure 4 The pipe cutting method provided in this application embodiment will now be described. The pipe cutting method provided in this application embodiment is used to sequentially cut workpieces from a pipe along preset cutting points, with one workpiece cut from each preset cutting point. That is, cutting along one preset cutting point can produce one workpiece. It can be understood that the material head can be cut before cutting the first workpiece. Therefore, the rotary cutting mechanism can be positioned at the starting point of the material head and then moved along the first direction to cut the material head.

[0047] The pipe cutting method provided in this application includes steps S200, S400, S600, and S800.

[0048] S200, the pipe conveying mechanism drives the pipe to move along the first direction to convey the pipe.

[0049] The "first direction" is the same as the direction in which the pipe is transported.

[0050] S400, The rotary cutting mechanism moves a first preset distance along the first direction to cut the workpiece along the current preset cutting point.

[0051] In step S400, "the starting point position of the preset cutting point" refers to the starting position for cutting the preset cutting point. When the rotary cutting mechanism is located at the starting point position of the preset cutting point, the rotary cutting mechanism can complete the cutting of the current workpiece by moving a first preset distance along the first direction. It can be understood that before cutting the current preset cutting point, the rotary cutting mechanism can first move to the starting point position of the current preset cutting point.

[0052] Specifically, the rotary cutting mechanism can rotate 360° to perform a circumferential cut at the preset cutting point during cutting, thereby cutting out the workpiece.

[0053] By moving the rotary cutting mechanism along the first direction, the rotary cutting mechanism can track and cut the current preset cutting point, realizing the synchronous operation of feeding and cutting, thus improving work efficiency.

[0054] S600, the rotary cutting mechanism moves a second preset distance along the second direction to the starting position of the next preset cutting point. The second direction is opposite to the first direction, and the first preset distance is equal to the second preset distance.

[0055] In step S600, the rotary cutting mechanism moves a second preset distance along the second direction to reach the starting position of the next preset cutting point. The second direction is opposite to the first direction, meaning it is opposite to the conveying direction of the pipe. "The second preset distance is equal to the first preset distance" means that the rotary cutting mechanism moves the same distance along the second direction as it did when cutting the current preset cutting point, and then retracts the same distance along the second direction when cutting the next preset cutting point. When cutting two adjacent workpieces, the first preset distance the rotary cutting mechanism moves along the first direction can be the same or different.

[0056] For example, when three workpieces need to be cut, the first preset distance the rotary cutting mechanism needs to move along the first direction to cut the first workpiece is 50mm, the first preset distance to cut the second workpiece is 20mm, and the first preset distance to cut the third workpiece is 50mm. First, the rotary cutting mechanism moves 50mm along the first direction to cut the first workpiece. After the first workpiece is cut, the rotary cutting mechanism moves 50mm along the second direction to reach the starting point of the second preset cutting point. The rotary cutting mechanism continues to move 20mm along the first direction to cut the second workpiece. After the second workpiece is cut, the rotary cutting mechanism moves 20mm along the second direction to reach the starting point of the third preset cutting point. The rotary cutting mechanism continues to move 50mm along the first direction to cut the third workpiece.

[0057] S800: Compare the starting positions of the rotary cutting mechanism when it moves to two adjacent or more preset cutting points, and obtain the position deviation value. If the position deviation value exceeds the preset range, adjust the feeding speed of the pipe conveying mechanism.

[0058] In step S800, "the starting point position of two adjacent preset cutting points" refers to comparing the starting point positions of the rotating cutting mechanism at two adjacent preset cutting points. For example, comparing the starting point position of the rotating cutting mechanism when it moves to the first preset cutting point with the starting point position when it moves to the second preset cutting point, and the starting point position of the rotating cutting mechanism when it moves to the second preset cutting point with the starting point position when it moves to the third preset cutting point.

[0059] "The starting position of two preset cutting points spaced more than one apart" refers to comparing the starting positions of the rotary cutting mechanism when they are located at two preset cutting points spaced more than one apart. For example, when the rotary cutting mechanism is located at the starting position of two preset cutting points spaced one apart, the starting position of the rotary cutting mechanism is compared once every preset cutting point. For example, when the rotary cutting mechanism moves to the starting position of the first preset cutting point and moves to the starting position of the third preset cutting point, the starting position of the rotary cutting mechanism moves to the third preset cutting point and moves to the starting position of the fifth preset cutting point, and so on, the comparison is performed once every preset cutting point.

[0060] When comparing the starting positions of the rotary cutting mechanism at two preset cutting points spaced two apart, the starting position of the rotary cutting mechanism is compared every two preset cutting points. For example, when the rotary cutting mechanism moves to the starting position of the first preset cutting point and the starting position of the fourth preset cutting point, the starting position of the rotary cutting mechanism moves to the fourth preset cutting point and the starting position of the fourth preset cutting point and the starting position of the seventh preset cutting point, and so on, the comparison is performed every two preset cutting points.

[0061] By comparing the starting positions of the rotary cutting mechanism when it moves to two adjacent or more preset cutting points, the position deviation value is obtained. If the position deviation value exceeds the preset range, the feeding speed of the pipe conveying mechanism is adjusted. In this way, the feeding speed of the pipe conveying mechanism can be adjusted in real time by comparing the position deviation value of the rotary cutting mechanism when it moves to two adjacent or more preset cutting points, so as to avoid the rotary cutting mechanism moving beyond the stroke range in the first direction due to the feeding speed of the pipe conveying mechanism being too fast or too slow during the actual cutting process, thus ensuring the effective cutting.

[0062] The pipe cutting method provided in this application embodiment involves a pipe conveying mechanism that moves the pipe along a first direction to transport the pipe, and a rotary cutting mechanism that moves a first preset distance along the first direction to cut the workpiece at the current preset cutting point. The rotary cutting mechanism then moves a second preset distance along a second direction to the starting point of the next preset cutting point. The second direction is opposite to the first direction, and the first preset distance is equal to the second preset distance. This allows for sequential tracking and cutting of each preset cutting point, achieving synchronous feeding and cutting, and improving work efficiency. Furthermore, by comparing the starting points of the rotary cutting mechanism at two adjacent or more preset cutting points, a position deviation value is obtained. If the position deviation value exceeds a preset range, the feeding speed of the pipe conveying mechanism is adjusted. This allows for real-time adjustment of the feeding speed of the pipe conveying mechanism by comparing the position deviation values ​​of the rotary cutting mechanism at two adjacent or more preset cutting points, preventing the rotary cutting mechanism from exceeding its travel range along the first direction due to excessively fast or slow feeding speeds during actual cutting, thus ensuring effective cutting.

[0063] Please see Figure 2 Step S800, “comparing the starting positions of the rotary cutting mechanism when it moves to two adjacent or more preset cutting points, and obtaining the position deviation value, if the position deviation value exceeds the preset range, the feeding speed of the pipe conveying mechanism is adjusted”, may specifically include steps S810, S820, S830, S840, and S850.

[0064] S810. Obtain the starting position a of the rotary cutting mechanism at the nth preset cutting point, where n≥1.

[0065] In step S810, n can be a natural number such as 1, 2, 3, 4...

[0066] S820. Obtain the starting position b of the rotary cutting mechanism at the (n+m)th preset cutting point, where m≥1.

[0067] In step S820, m can be a natural number such as 1, 2, 3, 4, ... When m = 1, it indicates that the rotary cutting mechanism has moved to the starting point position of two adjacent preset cutting points. When m = 2, it indicates that the rotary cutting mechanism has moved to the starting point position of two preset cutting points spaced one apart. When m = 3, it indicates that the rotary cutting mechanism has moved to the starting point position of two preset cutting points spaced two apart.

[0068] S830. If the first preset value < ab < the second preset value, then determine whether a is greater than b.

[0069] In step S830, the first preset value can be -30 to -5 mm, for example, -30 mm, -15 mm, or -5 mm. The second preset value can be 5 to 30 mm, for example, 5 mm, 15 mm, or 30 mm.

[0070] S840. If a > b, the feeding speed of the pipe conveying mechanism increases according to the first preset adjustment coefficient.

[0071] In step S840, when a > b, it indicates that the feeding speed of the pipe conveying mechanism is slow, and the feeding speed needs to be increased incrementally according to the first preset adjustment coefficient. Specifically, the feeding speed of the pipe conveying mechanism before cutting the nth workpiece is defined as V. a Define the feeding speed of the pipe conveying mechanism as V when cutting the (n+m)th workpiece. b Let the first preset adjustment coefficient be A, then V b =V a (1+A).

[0072] The first preset adjustment coefficient A can be 5% to 15%, for example, it can be 5%, 10%, or 15%.

[0073] S850. If a < b, the feeding speed of the pipe conveying mechanism shall be reduced according to the second preset adjustment coefficient.

[0074] In step S850, when a < b, it indicates that the feeding speed of the pipe conveying mechanism is too fast, and the feeding speed needs to be reduced according to the second preset adjustment coefficient. Specifically, the feeding speed of the pipe conveying mechanism before cutting the nth workpiece is defined as V. aDefine the feeding speed of the pipe conveying mechanism as V when cutting the (n+m)th workpiece. b Let the second preset adjustment coefficient be B, then V b =V a (1-B).

[0075] The second preset adjustment coefficient B can be 5% to 15%. For example, it can be 5%, 10%, or 15%.

[0076] Step S800, "comparing the starting positions of the rotary cutting mechanism when it moves to two adjacent or more preset cutting points, and obtaining the position deviation value; if the position deviation value exceeds the preset range, adjusting the feeding speed of the pipe conveying mechanism", may also include step S860.

[0077] S860. If ab ≤ the first preset value, or ab ≥ the second preset value, then the feeding speed of the pipe conveying mechanism shall not be adjusted.

[0078] In step S860, if ab ≤ the first preset value or ab ≥ the second preset value, the pipe conveying mechanism continues to feed at the original feeding speed.

[0079] Step S810: Obtain the starting position a of the rotary cutting mechanism at the nth preset cutting point, where n≥1. This step may also include the following steps:

[0080] Obtain the theoretical feeding speed of the pipe conveying mechanism;

[0081] The pipe conveying mechanism is used to convey pipes at the theoretical feeding speed.

[0082] The rotary cutting mechanism rotates in opposite directions when cutting two adjacent preset cutting points. In actual operation, the rotary cutting mechanism needs to connect many cables, and if it rotates in the same direction, the cables are prone to tangling. Reversing the rotation direction of the rotary cutting mechanism between adjacent pipe cuts avoids cable tangling and prevents it from affecting equipment operation.

[0083] For example, when the rotary cutting mechanism rotates clockwise to cut the nth preset cutting point, it rotates counterclockwise to cut the (n+1)th preset cutting point.

[0084] Before step S400, where the rotary cutting mechanism moves a first preset distance along the first direction to cut the workpiece along the current preset cutting point, step S300 may also be included:

[0085] S300, Activate the coupling between the speed of the rotary cutting mechanism moving along the first direction and the feeding speed of the pipe conveying mechanism, so that the speed of the rotary cutting mechanism moving along the first direction satisfies the following formula:

[0086] V 切割 =V 管 +△V;

[0087] The feeding speed of the pipe conveying mechanism is defined as V. 管 The rotary cutting mechanism moves at a speed of V along the first direction. 切割 The preset speed is ΔV.

[0088] The preset speed ΔV can be set according to actual needs, and ΔV can be greater than or equal to or less than 0. When ΔV > 0, the speed at which the rotary cutting mechanism moves along the first direction is greater than the feeding speed of the pipe conveying mechanism. When ΔV = 0, the speed at which the rotary cutting mechanism moves along the first direction is equal to the feeding speed of the pipe conveying mechanism. When ΔV < 0, the speed at which the rotary cutting mechanism moves along the first direction is less than the feeding speed of the pipe conveying mechanism.

[0089] Since the speed at which the rotary cutting mechanism moves along the first direction is coupled with the feeding speed of the pipe conveying mechanism, when the feeding speed of the pipe conveying mechanism is adjusted, the speed at which the rotary cutting mechanism moves along the first direction will also change synchronously.

[0090] After the pipe is cut, the speed at which the rotary cutting mechanism moves in the first direction can be decoupled from the feeding speed of the pipe conveying mechanism, that is, the speed at which the rotary cutting mechanism moves in the first direction does not change with the feeding speed of the pipe conveying mechanism.

[0091] Step S800, “Compare the starting positions of the rotary cutting mechanism when it moves to two adjacent or more preset cutting points, and obtain the position deviation value. If the position deviation value exceeds the preset range, adjust the feeding speed of the pipe conveying mechanism”, may also include step S900.

[0092] S900, the pipe conveying mechanism drives the pipe to move along the first direction at the adjusted feeding speed.

[0093] After adjusting the feeding speed of the pipe conveying mechanism in step S800, the pipe conveying mechanism continues to move the pipe along the first direction at the adjusted feeding speed, while the rotary cutting mechanism continues to cut the remaining pipe.

[0094] Please see Figure 3 The working steps of one specific embodiment of the pipe cutting method of this application are as follows:

[0095] Calculate the theoretical feeding speed of the pipe conveying mechanism;

[0096] The pipe conveying mechanism is made to convey the pipe at the theoretical feeding speed along the first direction, so that the actual feeding speed of the pipe conveying mechanism is the same as the theoretical feeding speed.

[0097] Record the starting position 'a' of the first preset cutting point where the rotary cutting mechanism was located before cutting the first workpiece, prior to speed adjustment;

[0098] The rotary cutting mechanism moves a first preset distance along a first direction, thereby cutting out the first workpiece;

[0099] The rotary cutting mechanism moves a second preset distance along the second direction to move to the starting position of the second preset cutting point;

[0100] The rotary cutting mechanism moves a first preset distance along a first direction, thereby cutting out a second workpiece;

[0101] The rotary cutting mechanism moves a second preset distance along the second direction to move to the starting position of the third preset cutting point;

[0102] Record the starting position b of the rotary cutting mechanism moving a second preset distance along the second direction to move to the third preset cutting point;

[0103] Determine if -15mm < ab < 15mm;

[0104] If -15mm < ab < 15mm, then determine whether a is greater than b;

[0105] If a > b, then the feeding speed of the pipe conveying mechanism is adjusted as follows: V b =V a (1+A), where the feeding speed of the pipe conveying mechanism before cutting the first workpiece is defined as V. a Define the feeding speed of the pipe conveying mechanism as V when cutting the third workpiece. b Define the first preset adjustment coefficient as A;

[0106] If a < b, then the feeding speed of the pipe conveying mechanism is adjusted as follows: V b =V a (1-B), where the feeding speed of the pipe conveying mechanism before cutting the first workpiece is defined as V. a Define the feeding speed of the pipe conveying mechanism as V when cutting the third workpiece. b The second preset adjustment coefficient is defined as B.

[0107] The pipe conveying mechanism continues to convey pipes at the adjusted feeding speed, while the rotary cutting mechanism continues to process the third workpiece.

[0108] Please see Figure 4This application also provides a pipe cutting device, including a pipe conveying mechanism 10, a rotary cutting mechanism 20, and a position comparison module (not shown). The pipe conveying mechanism 10 is used to drive the pipe 100 to move along a first direction to convey the pipe 100. The rotary cutting mechanism 20 moves a first preset distance along the first direction to cut the workpiece along the current preset cutting point. The rotary cutting mechanism 20 moves a second preset distance along a second direction to move to the starting position of the next preset cutting point. The second direction is opposite to the first direction, and the first preset distance and the second preset distance are equal.

[0109] The position comparison module is used to compare the starting positions of the rotary cutting mechanism 20 when it moves to two adjacent or more preset cutting points, and obtain the position deviation value. If the position deviation value exceeds the preset range, the feeding speed of the pipe conveying mechanism 10 is adjusted.

[0110] Please see Figure 4 The rotary cutting mechanism 20 may include a movable member (not shown), a rotating member 21, and a cutting head 22. The rotating member 21 is mounted on the movable member and driven by the movable member to move along a first direction and a second direction.
