[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] See also Figure 1 , Figure 1 1 is a flow chart of a method for cutting a circular tube workpiece according to an embodiment of the present invention. The method for cutting a circular tube workpiece according to the present invention comprises the following steps:

[0040] S101: Acquire size information and target processing information of a workpiece to be processed, where the target processing information includes the length of a long side and a short side of the target workpiece to be processed.

[0041] In a specific implementation scenario, the size information of the workpiece to be processed is obtained. The workpiece to be processed is a round tube workpiece. The size information includes at least one of the inner diameter, outer diameter, total length, and initial starting position of the workpiece to be processed. The target processing information for the workpiece to be processed is obtained. The target processing information includes the long side length and short side length of the target workpiece that the user wants to obtain. Please refer to Figure 2 , Figure 2 FIG. 1 is a front view schematic diagram of a target workpiece in one embodiment of the present invention. Figure 2 As shown in , the maximum length of the target workpiece in the extension direction is the long side length, and the minimum length is the short side length. The target workpiece has a symmetrical structure. The long and short lengths are greater than or equal to the short side length.

[0042] S102: Acquire a material head circular cutting position and a workpiece circular cutting position group of a target workpiece according to the size information, the long side length, and the short side length. The workpiece circular cutting position group includes a first circular cutting position and a second circular cutting position.

[0043] In a specific implementation scenario, please refer to Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a workpiece to be processed in an embodiment of the present invention. Figure 3 As shown in , the material head is cut according to the starting position of the workpiece to be processed, and the first processing cut and the second processing cut are respectively performed at the first processing position and the second processing position to obtain two target processing workpieces.

[0044] The sprue cutting position, the first sprue cutting position, and the second sprue cutting position of the target workpiece are obtained based on the long side length and the short side length. The sprue cutting position, the first sprue cutting position, and the second sprue cutting position include the angular relationship between the workpiece to be processed in the extension direction (X-axis) and the A-axis (0-360 degrees), so that cutting can be performed based on the sprue cutting position, the first sprue cutting position, and the second sprue cutting position to obtain the target workpiece.

[0045] In this implementation scenario, the material head circular cutting position includes the material head circular cutting position point on the workpiece to be processed at each preset angle when the material head circular cutting is performed, the first circular cutting position includes the first circular cutting position point on the workpiece to be processed at each preset angle when the processing circular cutting is performed, and the second circular cutting position includes the second circular cutting position point on the workpiece to be processed at each preset angle when the processing circular cutting is performed. In this implementation scenario, the preset angle is 12 degrees. In other implementation scenarios, the preset angle can also be 6 degrees, 10 degrees, etc., and can be set according to the user's processing requirements such as processing accuracy and processing efficiency.

[0046] Please refer to Figure 4 and Figure 5 , Figure 4A schematic diagram of the angle vector in the right-view reference plane when the A-axis angle is in the range of 0-90 degrees in one embodiment of the present invention. Figure 5 This is a schematic diagram of the position of the corresponding position point on the front view reference plane when the A axis angle is within the range of 0-90 degrees in the right view reference plane in one embodiment of the present invention. Figure 4 As shown in , the relationship between the angle of the A axis and the length of the long side and the length of the short side is:

[0047]

[0048] like Figure 5 As shown in , the cutting position corresponding to the angle A is projected onto the front reference plane to obtain the following formula, where x is a negative value:

[0049]

[0050] Combine the above two formulas to obtain the relationship between the cutting position x corresponding to angle A, the long side length a, and the short variable length b:

[0051]

[0052] Where a is the length of the long side, b is the length of the short side, A is any angle between 0° and 90° on the A axis, and d is the outer diameter of the round tube of the workpiece to be processed.

[0053] Please refer to Figure 6 and Figure 7 , Figure 6 A schematic diagram of the angle vector in the right-view reference plane when the angle is in the range of 90-180 degrees in one embodiment of the present invention. Figure 7 A schematic diagram of the position of the corresponding position point on the front view reference plane when the A-axis angle is within the range of 90-180 degrees in the right view reference plane in one embodiment of the present invention. Figure 6 As shown in , the relationship between the angle of the A axis and the length of the long side and the length of the short side is:

[0054]

[0055] like Figure 7 As shown in , the cutting position corresponding to the angle A is projected onto the front reference plane to obtain the following formula, where x is a negative value:

[0056]

[0057] Combine the above two formulas to obtain the relationship between the cutting position x corresponding to angle A, the long side length a, and the short variable length b:

[0058]

[0059] Where a is the length of the long side, b is the length of the short side, A is any angle between 90° and 180° on the A axis, and d is the outer diameter of the round tube of the workpiece to be processed.

[0060] Please refer to Figure 8 and Figure 9 , Figure 8 A schematic diagram of the angle vector in the right-view reference plane when the A-axis angle is in the range of 180-270 degrees in one embodiment of the present invention. Figure 9 In one embodiment of the present invention, when the A-axis angle is within the range of 180-270 degrees in the right-view reference plane, the corresponding position point of the angle is shown in the schematic diagram on the front-view reference plane. Figure 8 As shown in , the relationship between the angle of the A axis and the length of the long side and the length of the short side is:

[0061]

[0062] like Figure 9 As shown in , the cutting position corresponding to the angle A is projected onto the front reference plane to obtain the following formula, where x is a negative value:

[0063]

[0064] Combine the above two formulas to obtain the relationship between the cutting position x corresponding to angle A, the long side length a, and the short variable length b:

[0065]

[0066] Where a is the length of the long side, b is the length of the short side, A is any angle between 180° and 270° on the A axis, and d is the outer diameter of the round tube of the workpiece to be processed.

[0067] Please refer to Figure 10 and Figure 11 , Figure 10 A schematic diagram of the angle vector in the right-view reference plane when the A-axis angle is in the range of 270-360 degrees in one embodiment of the present invention. Figure 11 The following is a schematic diagram of the position of the corresponding position point on the front view reference plane when the A axis angle is within the range of 270-360 degrees in the right view reference plane in one embodiment of the present invention. Figure 10 As shown in , the relationship between the angle of the A axis and the length of the long side and the length of the short side is:

[0068]

[0069] like Figure 11 As shown in , the cutting position corresponding to the angle A is projected onto the front reference plane to obtain the following formula, where x is a negative value:

[0070]

[0071] Combine the above two formulas to obtain the relationship between the cutting position x corresponding to angle A, the long side length a, and the short variable length b:

[0072]

[0073] Where a is the length of the long side, b is the length of the short side, A is any angle between 180° and 270° on the A axis, and d is the outer diameter of the round tube of the workpiece to be processed.

[0074] Based on the results of the above four interval analyses, the relationship between the material head circular cutting position point x0 and the A-axis angle is:

[0075]

[0076] Among them, x0 is the circumferential cutting position of the material head, a is the length of the long side, b is the length of the short side, and A is any angle between 0° and 360°.

[0077] According to the material head circular cutting position point x0, the relationship between the first circular cutting position point x1 and the second circular cutting position point x2 and the A-axis angle can be calculated as follows:

[0078]

[0079]

[0080] Among them, x1 is the first ring cutting position point, x2 is the second ring cutting position point, a is the length of the long side, b is the length of the short side, and A is any angle between 0° and 360°.

[0081] S103: After performing material head circular cutting according to the material head circular cutting position, perform N processing circular cutting according to the workpiece circular cutting position group to obtain 2N target processing workpieces, where N is an integer greater than 0.

[0082] In a specific implementation scenario, please continue to refer to Figure 3 ,like Figure 3 As shown, the material head circular cutting operation is first performed according to the material head circular cutting position, and then N processing circular cutting operations are performed according to the workpiece circular cutting position group. The workpiece circular cutting position group includes a first circular cutting position and a second circular cutting position. A processing circular cutting operation is performed according to the workpiece circular cutting position group to obtain two target processing workpieces. Therefore, N processing circular cutting operations can obtain 2N processing workpieces.

[0083] In other implementation scenarios, the target number of processing can be obtained in advance. When the target number of processing is an odd number, the last processing spiral cutting operation is performed based only on the first spiral cutting position. For example, if the target number of processing is 3, the second processing spiral cutting operation is performed based only on the first spiral cutting position.

[0084] In other implementation scenarios, after the material head circular cutting operation is completed, the number of completed workpieces is increased by one when the circular cutting operation is performed according to the first circular cutting position, and the number of completed workpieces is increased by one when the circular cutting operation is performed according to the second circular cutting position. Therefore, when circular cutting is performed N times according to the workpiece circular cutting position group, the number of completed workpieces is increased by one each time a circular cutting operation is completed, and the current number of completed workpieces is counted. If the current number of completed workpieces is equal to the target processing number, subsequent operations are suspended. If it is less than the target processing number, subsequent circular cutting operations are continued.

[0085] In this implementation scenario, the second circular cutting position during the last circular cutting process is obtained, and the second circular cutting position during the last circular cutting process is used as the material head circular cutting position during the current circular cutting process. For example, if the target processing quantity is 4, then after the material head circular cutting operation is performed, the circular cutting operation is first performed according to the first circular cutting position x1 and the second circular cutting position x2 obtained in the above steps to obtain 2 target processing workpieces. When the next circular cutting operation is performed, the second circular cutting position x2 is used as the material head circular cutting position x0 in the next circular cutting operation. Based on the new material head circular cutting position x0, the new first circular cutting position x1 and the second circular cutting position x2 are obtained to perform the next circular cutting operation.

[0086] From the above description, it can be seen that in this embodiment, the material head circular cutting position and the workpiece circular cutting position group of the target processing workpiece are obtained according to the size information, the long side length and the short side length. The workpiece circular cutting position group includes a first circular cutting position and a second circular cutting position. After the material head circular cutting is performed according to the material head circular cutting position, N processing circular cuttings are performed according to the workpiece circular cutting position group to obtain 2N target processing workpieces. When processing workpieces of the same specifications but different target processing sizes, there is no need to program them separately. Only the long side length and the short side length need to be input to obtain the required circular cutting position, which effectively improves work efficiency and reduces workload.

[0087] See also Figure 12 , Figure 12 FIG. 1 is a schematic structural diagram of an embodiment of a round tube workpiece cutting system provided by the present invention. The round tube workpiece cutting system 10 includes an acquisition module 11 , a position module 12 and a ring cutting module 13 .

The circular cutting module 13 is used to perform circular cutting according to the material head circular cutting position, and then perform N processing circular cutting according to the workpiece circular cutting position group to obtain 2N target processing workpieces, where N is an integer greater than 0.

[0089] The material head circular cutting position includes the material head circular cutting position point on the workpiece to be processed at each preset angle when the material head circular cutting is performed; the first circular cutting position includes the first circular cutting position point on the workpiece to be processed at each preset angle when the processing circular cutting is performed; the second circular cutting position includes the second circular cutting position point on the workpiece to be processed at each preset angle when the processing circular cutting is performed.

[0090] The position module 12 is further configured to obtain the material head circular cutting position according to the following formula:

[0091]

[0092] Among them, x0 is the circumferential cutting position of the material head, a is the length of the long side, b is the length of the short side, and A is any angle between 0° and 360°.

[0093] The position module 12 is further configured to obtain the first circumcision position according to the following formula:

[0094]

[0095] Where x1 is the first ring cutting point, a is the length of the long side, b is the length of the short side, and A is any angle between 0° and 360°.

[0096] The position module 12 is further configured to obtain the second circumcision position according to the following formula:

[0097]

[0098] Where x2 is the second ring cutting point, a is the length of the long side, b is the length of the short side, and A is any angle between 0° and 360°.

[0099] The circular cutting module 13 is further configured to obtain the second circular cutting position during the last circular cutting process, and use the second circular cutting position during the last circular cutting process as the material head circular cutting position during the current circular cutting process.

[0100] The target processing information includes the target processing quantity. The ring cutting module 13 is further configured to perform the ring cutting operation only according to the first ring cutting position when executing the last ring cutting when the target processing quantity is an odd number.

[0101] From the above description, it can be seen that in this embodiment, the material head circular cutting position and the workpiece circular cutting position group of the target processing workpiece are obtained according to the size information, the long side length and the short side length. The workpiece circular cutting position group includes a first circular cutting position and a second circular cutting position. After the material head circular cutting is performed according to the material head circular cutting position, N processing circular cuttings are performed according to the workpiece circular cutting position group to obtain 2N target processing workpieces. When processing workpieces of the same specifications but different target processing sizes, there is no need to program them separately. Only the long side length and the short side length need to be input to obtain the required circular cutting position, which effectively improves work efficiency and reduces workload.
