Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
It should be noted that the terms "first," "second," "third," "fourth," "fifth," and "sixth," etc. in the description and claims of the present invention and the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.
Next, for convenience of description, the first length is L1, the second length is L2, the third length is L3, the fourth length is L4, the fifth length is L5, and the sixth length is L6.
As shown in fig. 1, an embodiment of the present invention provides a pipe cutting control method, including:
step S110, setting a first length as the length of a part to be processed; detecting that the actual length of the pipe before cutting is a second length; and detecting the length of the pipe which cannot be cut by the laser cutting head 5 clamped in the first chuck 1 and the second chuck 2 as a third length.
Specifically, L1 may be set according to actual processing requirements, and L3 may be determined according to the model or size of the dual-chuck laser cutting machine.
As shown in fig. 1, in step S120, if the sum of the first length and the third length is less than or equal to the second length, a first cutting mode is operated.
Specifically, the first cutting mode is a conventional cutting mode of the tube, i.e. the tube clamped in the first chuck 1 and the second chuck 2 cannot be cut, and the segment L3 needs to be treated as a waste. For example: when the length of the pipe L2 to be cut is detected to be 10m, the length L1 of a part to be processed is set to be 3m, and the length of the pipe L3 clamped in the first chuck 1 and the second chuck 2 is 1.5 m. According to the judgment condition: l1+ L3 is not less than L2, and when the judgment result shows that 3+1.5 is not more than 10, a first cutting mode is adopted.
As shown in fig. 3, the first cutting mode includes, at step S123: the first chuck 1 and the second chuck 2 fix the pipe, and the first chuck 1 controls the laser cutting head 5 to cut the pipe once after driving the pipe to move for a first length relative to the second chuck 2.
Specifically, for example: when the length of the pipe L2 to be cut is detected to be 10m, the length L1 of a part to be processed is set to be 3m, and the length of the pipe L3 clamped in the first chuck 1 and the second chuck 2 is 1.5 m. The first chuck 1 controls the pipe to move forward 3m towards the cutting head every time, the laser cutting head 5 cuts the pipe once, and after the first cutting, the remaining length of the pipe is L2-L1, namely 10m-3m is 7 m; after the second cutting, the residual length of the pipe is 7m-3 m-4 m; thirdly, since the first chuck 1 controls the movement of the pipe to have a limit length of 4m-1.5 m-2.5 m, the first cutting mode cannot perform the third cutting on the pipe.
As shown in fig. 1, in step S130, if the second length is greater than the first length, and the sum of the first length and the third length is greater than the second length, a second cutting mode is executed.
Specifically, the second cutting mode is a zero-tailing cutting mode, that is, the tube clamped in the first chuck 1 and the second chuck 2 is taken as a part of the part to be processed, that is, the length of the L3 is calculated as the length of the part to be processed, and redundant parts are cut off. For example: when the length of the pipe L2 to be cut is detected to be 4m, the length L1 of a part to be processed is set to be 3m, and the length of the pipe L3 clamped in the first chuck 1 and the second chuck 2 is 1.5 m. According to the judgment condition: l1 < L2 < L1+ L3, and when it is judged that 3m < 4m < 1.5m +3m, the second cutting mode is adopted.
As shown in fig. 4, step S131, the second cutting mode includes: the first chuck 1 and the second chuck 2 fix the pipe, and after the first chuck 1 drives the pipe to move for a sixth length relative to the second chuck 2, the laser cutting head 5 is controlled to cut the pipe; wherein the sixth length is the second length minus the first length.
Specifically, for example: when the length of the pipe L2 to be cut is detected to be 4m, the length L1 of a part to be processed is set to be 3m, and the length of the pipe L3 clamped in the first chuck 1 and the second chuck 2 is 1.5 m. Since 1.5m held between the first chuck 1 and the second chuck 2 cannot be cut, the tube is cut off with L6, L6 ═ L2-L1, that is, L6 ═ 4m-3m ═ 1 m. The length of the cut tube was 3m and the scrap was 1 m. Therefore, the waste of the pipe can be effectively avoided, and the generation of tailings is reduced.
As shown in fig. 5, step S124, before the first cutting mode is turned on, further includes: detecting whether the end part of the pipe to be cut is flat or not; and if the end part of the pipe is not flat, controlling the laser cutting head 5 to flatten the end part of the pipe, and detecting the second length again after flattening the end part of the pipe.
When the end face of the incoming pipe is uneven, errors may exist in the length measurement of the pipe, and the unevenness of the end face of the pipe may also cause the pipe processed by subsequent cutting to be not in accordance with the related quality standard. The incoming material pipe is after by the centre gripping of first chuck 1 and second chuck 2, can detect the terminal surface of incoming material pipe through image acquisition equipment such as cameras, when detecting the terminal surface unevenness of pipe, can control laser cutting head 5 with the end excision of pipe, specific excision length can be confirmed according to actual need.
Secondly, the ends at the two ends of the pipe can be respectively detected, and the following four conditions can occur. Firstly, one end of the pipe close to the cutting head is uneven, and the other end of the pipe far away from the cutting head is even; secondly, one end of the pipe close to the cutting head is uneven, and the other end of the pipe far away from the cutting head is uneven; thirdly, one end of the pipe close to the cutting head is flat, and the other end of the pipe far away from the cutting head is not flat; fourthly, flattening one end of the pipe close to the cutting head, and flattening one end of the pipe far away from the cutting head;
when the first condition or the third condition occurs, the end surface flatness condition of the pipe can be detected before the pipe is fed, so that the placing directions of two ends of the pipe are determined for feeding, and the laser cutting head 5 is used for cutting off the uneven end; for example, when the length of the pipe L2 is detected to be 5.1m, due to the fact that the end of the pipe close to the laser cutting head 5 is uneven, in order to guarantee the accuracy and quality of subsequent pipe processing, the end can be cut off by 0.1m, the length of the L2 can be detected again, and the newly determined length of the L2 is 5.1m-0.1 m-5 m.
When the second condition occurs, the laser cutting head 5 firstly cuts off the end head of one end of the pipe, and then turns the directions of the two ends of the pipe, so that the laser cutting head 5 cuts off the other end which is not flat; for example, when the length of the pipe L2 is detected to be 5.1m, both ends of the pipe can be cut off by 0.1m to ensure the precision and quality of subsequent pipe processing due to the fact that both ends of the pipe are uneven, the length of the L2 can be detected again, and the newly determined length of the L2 is 5.1m-0.1 m-4.9 m.
When the fourth situation occurs, the pipe can now be directly processed for further processing.
As shown in fig. 2, step S121, after the first cutting mode is turned on, further includes: detecting that the actual length of the cut pipe is a fourth length; if the sum of the first length and the third length is less than or equal to the fourth length, continuing to operate the first cutting mode; and if the fourth length is greater than the first length and the sum of the first length and the third length is greater than the fourth length, operating the second cutting mode.
In one embodiment of the invention, for example: when the length of the pipe L2 to be cut is detected to be 7m, the length L1 of a part to be processed is set to be 3m, and the length of the pipe L3 clamped in the first chuck 1 and the second chuck 2 is 1.5 m. When the first chuck 1 controls the tube to advance 3m towards the cutting head for the first time, the laser cutting head 5 cuts the tube for the first time, the cut tube of 3m is collected for the subsequent process, and the length L4 of the tube on the first chuck 1 and the second chuck 2 is L2-L1, that is, 7m-3m is 4 m.
In the present case, it is redetected that the length of L4 is 4m, the length of L1 is 3m, and the length of L3 is 1.5 m. According to the judgment condition: l2 is more than L1, and 4m is more than 3 m; according to the judgment condition: l1+ L3 > L4, 3M +1.5M > 4M was judged. At this time, the second cutting mode is operated.
As shown in fig. 2, in step S122, the second cutting mode includes: the first chuck 1 and the second chuck 2 fix the pipe, and after the first chuck 1 drives the pipe to move for a fifth length relative to the second chuck 2, the laser cutting head 5 is controlled to cut the pipe; wherein the fifth length is the fourth length minus the first length.
In order to avoid the waste of the pipe, the 4m pipe needs to be utilized, and the 4m pipe is cut into a section of 3m pipe, so that only 1m of tailings is guaranteed. Since 1.5m held between the first chuck 1 and the second chuck 2 cannot be cut, the tube is cut off with L5, L5 ═ L4-L1, that is, L5 ═ 4m-3m ═ 1 m. At this time, the length of the cut pipe L4 is 3m, and L4 is L1, so that three 3m pipe pieces can be cut from one 10m long pipe, the scrap is 1m, and only two 3m pipe pieces can be cut from the first cutting mode, and the scrap is 4 m. Therefore, the waste of the pipe can be effectively avoided, and the generation of tailings is reduced.
In another embodiment of the invention, for example: when the length of the pipe L2 to be cut is detected to be 10m, the length L1 of a part to be processed is set to be 3m, and the length of the pipe L3 clamped in the first chuck 1 and the second chuck 2 is 1.5 m. When the first chuck 1 controls the tube to advance 3m towards the cutting head for the first time, the laser cutting head 5 cuts the tube for the first time, the cut tube of 3m is collected for the subsequent process, and the length L4 of the tube on the first chuck 1 and the second chuck 2 is L2-L1, namely 10m-3m is 7 m.
In the present case, it is redetected that the length of L4 is 7m, the length of L1 is 3m, and the length of L3 is 1.5 m. According to the judgment condition: l1+ L3 is not more than L4, and 3m +1.5m is less than 7 m. At this time, the first cutting mode is continuously operated, the first chuck 1 controls the pipe to continuously advance for 3m, and the laser cutting head 5 cuts the pipe again.
The first cutting mode comprises: the first chuck 1 and the second chuck 2 fix the pipe, and the first chuck 1 continues to drive the pipe to move for a first length relative to the second chuck 2 and then controls the laser cutting head 5 to cut the pipe once.
Specifically, the length of L4 was redetected to be 7m, the length of L1 to be 3m, the length of the part to be machined L1 to be 3m, and the length of the tube L3 clamped in the first chuck 1 and the second chuck 2 to be 1.5 m. The first chuck 1 continuously controls the pipe to move forward 3m towards the cutting head, the laser cutting head 5 cuts the pipe once, and after the cutting is finished, the remaining length of the pipe is L4-L1, namely 7m-3m is 4 m.
The pipe cutting control method can ensure that the first length, the second length and the third length before the incoming pipe is cut are collected. Judging according to a judgment condition, and if the sum of the first length and the third length is less than or equal to the second length, operating a first cutting mode; and if the second length is greater than the first length and the sum of the first length and the third length is greater than the second length, entering a second cutting mode. Therefore, the first cutting mode or the second cutting mode is intelligently selected according to the judgment conditions among the first length, the second length and the third length, excessive waste of the pipe is avoided, particularly for heavy pipes, cost increase caused by discarding of the tailings due to incapability of cutting and using is avoided, when the first cutting mode is incapable of cutting the pipe, the second cutting mode is adopted and the tailings are utilized, and waste of the tailings is reduced.

the acquiring unit 10 is used for acquiring a first length, a second length and a third length of the pipe;
and the control unit 20 is configured to control the laser pipe cutting machine to enter the first cutting mode or the second cutting mode according to the judgment condition among the first length, the second length, and the third length.
In this way, the obtaining unit 10 detects the first length, the second length and the third length of the pipe and the size relationship between the first length, the second length and the third length, and transmits the detected data to the control unit 20, and the control unit 20 processes and analyzes the received data and controls the laser pipe cutting machine to start the first cutting mode or the second cutting mode, so that the generation of tailings is reduced, and the waste of excessive pipes is avoided.
