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

[0019] Furthermore, the rotation directions of the rotary cutting mechanism for cutting two adjacent preset cutting points are opposite.

[0045] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0046] See also Figure 1 and Figure 4 , the pipe cutting method provided in the embodiment of the present application is now described. The pipe cutting method provided in the embodiment of the present application is used to cut workpieces on the pipe in sequence along the preset cutting points, and one preset cutting point cuts one workpiece. That is, cutting along one preset cutting point can cut one workpiece. It can be understood that the material head can be cut before cutting the first workpiece, so the rotating cutting mechanism can be first located 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 the embodiment of the present application includes steps S200, S400, S600, and S800.

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

[0049] The “first direction” is the same as the conveying direction of the pipe.

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

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

[0052] Specifically, the rotary cutting mechanism can rotate 360° during cutting to perform circular cutting on a preset cutting point, thereby cutting out a 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, thereby achieving synchronous feeding and cutting, thereby improving work efficiency.

[0054] S600, the rotary cutting mechanism moves a second preset distance along a second direction to move to a starting point position of a 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 in the second direction to move to the starting point position of the next preset cutting point. The second direction is opposite to the first direction, that is, the second direction is opposite to the conveying direction of the pipe. "The second preset distance is equal to the first preset distance", that is, the rotary cutting mechanism moves a certain distance in the first direction when cutting the current preset cutting point, and needs to retreat the same distance in the second direction when cutting the next preset cutting point. When cutting two adjacent workpieces, the first preset distance moved by the rotary cutting mechanism in the first direction can be the same or different.

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

[0057] S800, comparing the starting point positions of the rotary cutting mechanism when it moves to two adjacent or more than one preset cutting points, and obtaining a position deviation value. If the position deviation value exceeds a preset range, adjusting 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 position of the rotating cutting mechanism at two adjacent preset cutting points, for example, comparing the starting point position of the rotating cutting mechanism moving to the first preset cutting point with the starting point position of the rotating cutting mechanism moving to the second preset cutting point, and comparing the starting point position of the rotating cutting mechanism moving to the second preset cutting point with the starting point position of the rotating cutting mechanism moving to the third preset cutting point.

[0059] “The starting point position of two preset cutting points separated by more than one” means comparing the starting point position of the rotary cutting mechanism at two preset cutting points separated by more than one. For example, when the rotary cutting mechanism is located at the starting point position of two preset cutting points separated by one, the starting point position to which the rotary cutting mechanism moves is compared once for each preset cutting point. For example, when the rotary cutting mechanism moves to the starting point position of the first preset cutting point and the starting point position of the third preset cutting point, the rotary cutting mechanism moves to the starting point position of the third preset cutting point and the starting point position of the fifth preset cutting point, and so on, the comparison is performed once for each preset cutting point.

[0060] When the comparison is made between the starting positions of the rotary cutting mechanism at two preset cutting points, the position of the starting point moved by the rotary cutting mechanism is compared once 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 rotary cutting mechanism moves to 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 once every two preset cutting points.

[0061] By comparing the starting positions of the rotating cutting mechanism when it moves to two preset cutting points that are adjacent or spaced apart by more than one, 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. Furthermore, the feeding speed of the pipe conveying mechanism can be adjusted in real time by comparing the starting positions of the rotating cutting mechanism at two preset cutting points that are adjacent or spaced apart by more than one, thereby avoiding the rotating cutting mechanism moving in the first direction exceeding the travel range due to the feeding speed of the pipe conveying mechanism being too fast or too slow during the actual cutting process, thereby ensuring effective cutting.

[0062] The pipe cutting method provided by the embodiment of the present application comprises the following steps: the pipe conveying mechanism drives the pipe to move along a first direction to convey the pipe, the rotary cutting mechanism moves a first preset distance along the first direction to cut a workpiece along the current preset cutting point, and the rotary cutting mechanism moves a second preset distance along the second direction 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 in turn, and the feeding and cutting can be carried out synchronously, thereby improving the working efficiency; and, by comparing the starting point positions of two preset cutting points adjacent or spaced by more than one when the rotary cutting mechanism moves, a position deviation value is obtained, and if the position deviation value exceeds the preset range, the feeding speed of the pipe conveying mechanism is adjusted, and then the feeding speed of the pipe conveying mechanism can be adjusted in real time by comparing the position deviation value of the starting point position of the rotary cutting mechanism at two preset cutting points adjacent or spaced by more than one, so as to avoid the travel of the rotary cutting mechanism moving along the first direction exceeding the travel range due to the excessively fast or too slow feeding speed of the pipe conveying mechanism in the actual cutting process, thereby ensuring the effective cutting.

[0063] See also Figure 2 Step S800 "compares the starting point positions of the rotating cutting mechanism when it moves to two adjacent or more than one preset cutting points, and obtains a position deviation value. If the position deviation value exceeds a preset range, the feeding speed of the pipe conveying mechanism is adjusted", which may specifically include steps S810, S820, S830, S840, and S850.

[0064] S810, obtaining the starting point 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 of 1, 2, 3, 4, ...

[0066] S820, obtaining the starting point position b of the rotary cutting mechanism at the n+mth preset cutting point, m≥1.

[0067] In step S820, m can be a natural number of 1, 2, 3, 4, etc. When m=1, it means that the comparative rotary cutting mechanism moves to the starting point position between two adjacent preset cutting points. When m=2, it means that the comparative rotary cutting mechanism moves to the starting point position between two preset cutting points that are one apart. When m=3, it means that the comparative rotary cutting mechanism moves to the starting point position between two preset cutting points that are two apart.

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

[0069] In step S830, the first preset value may be -30 to -5 mm, for example, -30 mm, -15 mm, or -5 mm. The second preset value may 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 is increased according to the first preset adjustment coefficient.

[0071] In step S840, when a>b, it means that the feeding speed of the pipe conveying mechanism is slow, and the feeding speed needs to be increased 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 when cutting the n+mth workpiece as V b , define the first preset adjustment coefficient as A, then V b =V a (1+A).

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

[0073] S850: If a<b, the feeding speed of the pipe conveying mechanism is decreased according to the second preset adjustment coefficient.

[0074] In step S850, when a<b, it means that the feeding speed of the pipe conveying mechanism is fast, and the feeding speed needs to be decreased 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 a, define the feeding speed of the pipe conveying mechanism when cutting the n+mth workpiece as V b , define the second preset adjustment coefficient as B, then V b =V a (1-B).

[0075] The second preset adjustment coefficient B may be 5% to 15%, for example, 5%, 10%, or 15%.

[0076] Step S800 "compares the starting point positions of the rotating cutting mechanism when it moves to two adjacent or more than one preset cutting points, and obtains a position deviation value. If the position deviation value exceeds a preset range, the feeding speed of the pipe conveying mechanism is adjusted", and may also include step S860.

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

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

[0079] Step S810, obtaining the starting point position a of the rotary cutting mechanism at the nth preset cutting point, n≥1, and the previous step may also include:

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

[0081] The feeding speed of the pipe conveying mechanism is set to the theoretical feeding speed to convey the pipe.

[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 more cables. If it rotates in the same direction, the cables are easily entangled. By making the rotary cutting mechanism rotate in opposite directions when cutting the pipe twice, the cable entanglement and affecting the operation of the equipment can be avoided.

[0083] For example, when the rotation direction of the rotary cutting mechanism for cutting the nth preset cutting point is clockwise, the rotation direction of the rotary cutting mechanism for the n+1th preset cutting point is counterclockwise. When the rotation direction of the rotary cutting mechanism for cutting the nth preset cutting point is counterclockwise, the rotation direction of the rotary cutting mechanism for the n+1th preset cutting point is clockwise.

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

[0085] S300, activating the speed of the rotating cutting mechanism moving along the first direction to couple with the feeding speed of the pipe conveying mechanism, so that the speed of the rotating cutting mechanism moving along the first direction satisfies the following formula:

[0086] V 切割 =V 管 +△V;

[0087] Among them, the feeding speed of the pipe conveying mechanism is defined as V 管 , the speed of the rotating cutting mechanism moving along the first direction is V 切割 , the preset speed is △V.

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

[0089] Since the speed of the rotary cutting mechanism moving along the first direction is coupled to the feeding speed of the tube conveying mechanism, when the feeding speed of the tube conveying mechanism is adjusted, the speed of the rotary cutting mechanism moving along the first direction will also change synchronously.

[0090] When the pipe cutting is completed, the speed of the rotating cutting mechanism moving along the first direction may be decoupled from the feeding speed of the pipe conveying mechanism, that is, the speed of the rotating cutting mechanism moving along the first direction may not change with the feeding speed of the pipe conveying mechanism.

[0091] Step S800, "compare the starting point positions of the rotating cutting mechanism when it moves to two adjacent or more than one 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", and then may include step S900.

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

[0093] After the feeding speed of the tube conveying mechanism is adjusted in step S800, the tube conveying mechanism drives the tube to continue to move along the first direction at the adjusted feeding speed, and the rotary cutting mechanism continues to cut the remaining tubes.

[0094] See also Figure 3 The working steps of one specific embodiment of the pipe cutting method of the present application are as follows:

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

[0096] The actual feeding speed of the pipe conveying mechanism is made equal to the theoretical feeding speed to convey the pipe along the first direction;

[0097] Record the starting point position a of the first preset cutting point where the rotary cutting mechanism is located before cutting the first workpiece before the speed is adjusted;

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

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

[0102] Recording that the rotary cutting mechanism moves a second preset distance along the second direction to a starting point position b of a third preset cutting point;

[0103] Judgment: -15mm<ab<15mm;

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

[0105] If a>b, the feeding speed of the pipe conveying mechanism is adjusted to: 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 when cutting the third workpiece as V b , define the first preset adjustment coefficient as A;

[0106] If a<b, the feeding speed of the pipe conveying mechanism is adjusted to: 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 when cutting the third workpiece as V b , define the second preset adjustment coefficient as B.

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

[0108] See also Figure 4The embodiment of the present application further 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 a workpiece along the current preset cutting point, and the rotary cutting mechanism 20 moves a second preset distance along the second direction 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.

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