Description

Technical Field

[0001] The present invention belongs to the field of pipe body processing, and in particular relates to a flaring control method, device, flaring machine and storage medium. Background Technique

[0002] Copper tubes, also known as red copper tubes, are a type of non-ferrous metal tubes. They are pressed and drawn seamless tubes. Copper tubes have the characteristics of good electrical conductivity and thermal conductivity. They are the main materials for conductive accessories and heat dissipation accessories of electronic products, and have become the first choice for modern contractors in the installation of tap water pipes, heating, and refrigeration pipes in all residential commercial houses. Copper tubes have poor corrosion resistance, are easy to oxidize, and react chemically with some liquid substances. They are easy to bend into shapes. Copper tubes are lighter in weight, have good thermal conductivity, and high low-temperature strength. They are commonly used in the manufacture of heat exchange equipment (such as condensers, etc.), and are also used in the assembly of low-temperature pipelines in oxygen production equipment. Small-diameter copper tubes are commonly used to transport pressurized liquids (such as lubrication systems, oil pressure systems, etc.) and as pressure measuring tubes for instruments.

[0003] After copper tubes are produced in a factory standard, their calibers are equal. To connect copper tubes, it is necessary to expand the caliber of the copper tubes. For the copper tubes used in equipment such as the two heat exchangers of air conditioners, that is, U-shaped tubes, it is necessary to bend the copper tubes into a U shape and then flare the two ends of the copper tubes.

[0004] However, due to reasons such as the current copper tube material and the quality of the long U-shaped tube bender, problems of long and short tubes often occur, that is, one end of the U-shaped tube is higher / longer than the other end. Generally, taking the shorter tube body as the standard for downward flaring, the longer tube body is closer to the flaring cup, which leads to the problem that the longer tube body is flared too deeply and cracks occur, resulting in waste of copper tubes and uncontrollable quality. In addition to U-shaped tubes, when flaring one end of copper tubes in batches, there may also be problems of different tube body lengths.

[0005] Traditional detection methods are manual or visual detection, which are costly and cannot avoid the waste of flaring wrinkles. Therefore, it is necessary to adjust the process for the problem of height difference existing in such pipe bodies. Summary of the Invention

[0006] The present invention provides a flaring control method, device, flaring machine and storage medium to solve the technical problem that the longer tube body is flared too deeply and cracks occur due to the height difference of the pipe body mentioned in the background technique.

[0007] To achieve the above object, the specific technical solutions of the flaring control method, device, flaring machine and storage medium of the present invention are as follows:

[0018] Further, the segregation coefficient is calculated according to the following formula: k=(D 单 +D 裂 ) / D 单 , where k is the segregation coefficient, D 单 is the single flaring depth, and D 裂 is the flaring risk depth.

[0023] The second control unit is used to perform the last flaring on all the pipe bodies in sequence and callback the insertion depth of the pipe bodies to be adjusted according to the ratio of the first torque to the average flaring torque.

[0024] Further, the second control unit calculates the callback distance through the formula L=(D / N)*[(P1 / P 平均 ) - 1].

[0025] Further, the judgment unit includes an acquisition subunit, a comparison subunit and a recording subunit;

[0026] The acquisition subunit is used to acquire the segregation coefficient;

[0027] The comparison subunit is used to compare the real-time torque with the product of the segregation coefficient and the average flaring torque;

[0040] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

In addition, the terms "first", "second", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0044] Figure 1 The flowchart of an embodiment of the flaring control method is schematically shown. As Figure 1As shown, the flaring control method of the present invention is used to control the flaring cup 2 to be inserted into the pipe body for flaring, and includes the following steps:

[0045] S10. Divide the flaring into N times according to the flaring depth and the pipe body;

[0046] Specifically, since inserting the head of the flaring cup 2 into the pipe body completely for flaring at one time is not only not conducive to controlling the insertion depth, but also it is very likely to cause the pipe body to wrinkle or crack during one-time flaring. However, dividing the total flaring depth into several times can make the force received by the metal pipe 3 uniform and is not likely to cause the phenomenon of the mouth of the metal pipe 3 wrinkling.

[0047] Generally, N = 3, that is, the flaring depth is divided into 3 times to gradually complete the flaring. For example, if the required flaring depth is 15 mm, it is divided into 3 times, with each flaring depth of 5 mm, and the total flaring depth reaches 15 mm. Of course, in addition to evenly dividing the flaring depth, the flaring depth of each time can also be adjusted according to the situation. The value of N and the distribution of the flaring depth each time adopt the existing technology, and the present invention will not elaborate.

[0048] S20. Flare all the pipe bodies in sequence, and obtain the real-time torque and average flaring torque of each pipe body;

[0049] Specifically, the flaring cup 2 is driven by a driver to be inserted into the pipe orifice of the metal pipe 3, and thus the data of the driver is detected by a sensor to obtain the flaring torque. The flaring depth is in direct proportion to the flaring torque. Therefore, even if the driver moves the flaring cup 2 to the same position, due to the height difference of the pipe orifices of each pipe body, the actual insertion depth of the flaring cup 2 is not the same, and accordingly, the torque obtained by the driver is different: for the pipe body with a higher pipe orifice, the distance from the initial position of the flaring cup 2 is closer, so the insertion depth of the flaring cup 2 is deeper, and the obtained flaring torque is larger; for the pipe body with a lower pipe orifice, the distance from the initial position of the flaring cup 2 is farther, so the insertion depth of the flaring cup 2 is shallower, and the obtained flaring torque is smaller. In this way, the above-mentioned flaring torques are collected and the average value of the flaring torques is calculated as the standard reflecting the pipe body depth.

[0050] The above-mentioned driver can be different drivers according to the flaring machine. Such as Figure 2 and Figure 3 As shown, the flaring machine includes a cross beam 1, and the cross beam 1 is lifted by a first motor. A plurality of positioning holes 11 are formed in the cross beam 1, and a flaring cup 2 is inserted into the positioning holes 11. A stop head 21 is formed at the upper end of the flaring cup 2, and the stop head 21 abuts against the cross beam 1 to limit the end point of the movement of the flaring cup 2 by abutting against the cross beam 1.

[0051] The lower end of the flaring cup 2 is formed with a plug 22 having a conical surface. The plug 22 is used to insert into the pipe orifice of the pipe body 3 to flare the pipe body 3. A roller 4 is rotatably connected to the cross beam 1. The roller 4 is driven by a second motor 5 to translate on the cross beam 1. The first motor drives the cross beam 1 to descend, so that the flaring cup 2 enters the pipe orifice. The second motor 5 drives the roller 4 to move left and right to roll and press the upper end of the flaring cup 2, and further press each flaring cup 2 into the pipe body 3 to perform the pipe orifice. To sum up, the second motor 5 is a driver. Through the ETHERCAT bus technology, the PLC can read the torque of the servo motor in real time within a scanning cycle of 1 ms.

[0052] In this way, the cross beam 1 approaches the metal pipe 3 along the axial direction of the metal pipe 3, and the flaring cup 2 descends together with the cross beam 1. When the flaring cup 2 is inserted into the pipe orifice of the metal pipe 3, the flaring cup 2 stops due to contact with the metal pipe 3. The cross beam 1 moves until it stops at the first corresponding position. The roller 4 is driven by the second motor 5 to move, so as to press the flaring cup 2 down in sequence to flare the pipe orifice of the metal pipe 3. Since the stop head 21 abuts against the cross beam 1, the flaring cup 2 just completes the first flaring. Then the cross beam 1 continues to descend. Since the flaring cup 2 has been partially inserted into the metal pipe 3, the flaring cup 2 remains stationary. When the cross beam 1 moves until it stops at the second corresponding position, the roller 4 is driven by the second motor 5 to move, so as to press the flaring cup 2 down in sequence, so that the flaring cup 2 just completes the second flaring. And so on, the flaring cup 2 completes the flaring.

[0053] Of course, in addition to adopting the above structure, the flaring machine can also adopt methods such as directly pressing down by a telescopic cylinder to drive the flaring cup 2 to flare, and the torque of the corresponding telescopic cylinder can be detected. In addition, the same effect can also be achieved by moving the metal pipe 3 upward.

[0054] Among them, "flaring all pipe bodies in sequence" refers to any one of the first to N - 1 flarings. If N = 3, that is, flaring 3 times, then the subsequent only refers to the first and second flarings.

[0055] Moreover, obtaining the real-time torque and average flaring torque of each pipe body can be completed in one flaring process. For example, in the first flaring, obtain the real-time torque and average flaring torque of each pipe body; or obtain the average flaring torque in the first flaring and the real-time torque of each pipe body in the second flaring; or obtain the real-time torque of each pipe body in the first flaring and the average flaring torque of each pipe body in the second flaring. That is, the acquisition of the two quantities can be completed in one flaring or in any two flarings. Of course, calculating the average requires obtaining each data. The acquisition of the real-time torque of each pipe body here refers to using the real-time torque collected this time as the standard for subsequent comparison.

[0056] S30. Compare the real-time torque and the average flaring torque, determine the pipe body to be adjusted according to the comparison result, and record the real-time torque of the pipe body to be adjusted as the first torque;

[0057] Specifically, since the flaring depth is proportional to the torque, when the real-time torque is greater than the average flaring torque, it means that the insertion depth of the pipe body has been relatively deeper than that of other pipe bodies. Record the position of this pipe body, that is, complete the marking of this pipe body. Through the ETHERCAT bus technology, while the PLC obtains the torque, it can also obtain the position feedback of the motor encoder. Just record the position feedback of this motor encoder, so as to complete the determination of the pipe body to be adjusted.

[0058] S40. Perform the last flaring on all pipe bodies in sequence, and callback the insertion depth of the pipe body to be adjusted according to the ratio of the first torque to the average flaring torque.

[0059] Specifically, combined with the above-mentioned drive mechanism, only by slightly adjusting the height of the cross beam 1 upward can the callback of the insertion depth of the pipe body to be adjusted be completed to avoid flaring cracks.

[0060] The callback distance is calculated according to the following formula:

[0061] L=(D / N)*[(P1 / P 平均 )-1 ]

[0062] L: Callback distance

[0063] P1: First torque

[0064] P 平均 : Average flaring torque

[0065] D: Flaring depth

[0066] N: Number of flaring times.

[0067] Taking three flarings as an example, N = 3;

[0068] Therefore, (D / 3)* [(P1 / P 平均 )-1 ]=(D / 3)*(P1 / P 平均 )-D / 3. Since the torque of the metal pipe 3 is proportional to the depth, so (D / 3)*(P1 / P average)is the depth of the flaring cup entering the long pipe for the second time, and then subtracting D / 3 gives the height difference between the long pipe and the normal metal pipe 3, providing data support for the subsequent slight lifting of the cross beam 1 for flaring.

[0069] Considering the error, even if there is a height difference at the pipe orifice, it may not necessarily cause flaring cracks. Therefore, comparing the real-time torque and the average flaring torque, determining the pipe body to be adjusted according to the comparison result includes:

[0070] S301. Obtain the segregation coefficient;

[0071] Specifically, the segregation coefficient K is the ratio between the torque feedback during actual flaring and cracking and the torque feedback when the flaring cup enters the metal tube 3. Taking the example of flaring 5 mm each time for a total of 15 mm, since there is a risk of cracking when it is 1 mm longer than the normal tube length in general, and the torque of the metal tube 3 is proportional to the depth, the K value is generally taken as (5 + 1) / 5 = 1.2.

[0072] That is, the segregation coefficient is calculated according to the following formula:

[0073] k = (D 单 + D 裂 ) / D 单

[0074] k: segregation coefficient;

[0075] D 单 : single flaring depth;

[0076] D 裂 : cracking risk depth.

[0077] S302. Compare the real-time torque with the product of the segregation coefficient and the average flaring torque;

[0078] S303. When the real-time torque is greater than the product of the segregation coefficient and the average flaring torque, record the current pipe body as the pipe body to be adjusted. Otherwise, it is a normal pipe body and no depth adjustment is required.

[0079] For the method embodiments, for the sake of simple description, they are all expressed as a series of action combinations. However, those skilled in the art should know that the embodiments of the present invention are not limited by the described action sequence, because according to the embodiments of the present invention, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily essential for the embodiments of the present invention.

[0080] For the understanding of the technical solution of the present invention, in combination with Figure 4 the flaring control method of the present application is further described: Figure 4 The flowchart of a flaring control method is schematically shown. In this embodiment, based on the above crossbeam structure flaring machine, the through hole is flared 15 mm in three times, and the segregation coefficient k = 1.2.

[0081] As Figure 4 shown, the flaring of the present invention includes the following processes:

[0082] 1. Start the flaring machine;

[0083] 2. Set the flaring parameters: the flaring depth D = 15 mm, and the segregation coefficient K = 1.2;

[0084] 3. Move the copper tubes of the two apparatuses into place;

[0085] 4. The crossbeam 1 is driven by the first motor to move downward to the first corresponding position. At this time, the flaring cup 2 moves with the crossbeam 1 and is inserted into the copper tube, and thus the flaring cup 2 is ejected from the upper side of the crossbeam 1;

[0086] 5. The second motor 5 drives the roller 4 to move left and right, rolls and presses the flaring cup 2 to flare by 5 mm, and real-time collects the servo feedback torque;

[0087] 6. The PLC calculates the average flaring torque during the flaring process;

[0088] 7. The crossbeam 1 descends to the second corresponding position. At this time, the flaring cup 2 remains stationary due to being inserted into the copper tube, so relative to the crossbeam 1, the flaring cup 2 is ejected and moves upward again;

[0089] 8. The second motor 5 drives the roller 4 to move left and right, rolls and presses the flaring cup for the second flaring of 5 mm, and real-time collects the servo feedback torque;

[0090] 9. When the real-time torque P 实时 > K * P 平均 is reached, record the encoder position F1 of the current second motor 5, that is, record the position of the tube body to be adjusted. Since the torque feedback of the flaring translation motor is proportional to the depth of the flaring cup entering the copper tube, at this time, it can be calculated that the copper tube at this place is 5 (P1 / P 平均 -1) longer than other places;

[0091] 10. The crossbeam 1 descends to the second corresponding position;

[0092] 11. The second motor 5 drives the roller 4 to move left and right, rolls and presses the flaring cup 2 for the second flaring of 5 mm, with a total of 15 mm; when the roller 4 moves to the F1 point, the crossbeam is slightly lifted by 5 (P1 / P 平均 -1) to adapt to the length of the copper tube and avoid flaring cracks;

[0093] 12. The crossbeam 1 and the roller 4 return to the initial position.

[0094] Figure 5 Schematically shows a structural schematic diagram of a flaring control device. As Figure 5 shown, an embodiment of the present invention also provides a flaring control device for controlling a flaring machine, including:

[0096] The first control unit 201 is configured to perform flaring on all the pipe bodies in sequence, and obtain the real-time torque and the average flaring torque of each pipe body.

[0097] The judgment unit 301 compares the real-time torque with the average flaring torque, determines the pipe bodies that need to be adjusted according to the comparison result, and records the real-time torque of the pipe bodies that need to be adjusted as the first torque.

[0098] The second control unit 401 is configured to perform the last flaring on all the pipe bodies in sequence, and callback the insertion depth of the pipe bodies that need to be adjusted according to the ratio of the first torque to the average flaring torque.

[0099] As an embodiment of the present invention, the second control unit calculates the callback distance through the formula L=(D / N)* [(P1 / P 平均 )-1].

[0100] Optionally, the judgment unit includes an acquisition subunit, a comparison subunit, and a recording subunit;

[0104] As an embodiment of the present invention, the acquisition subunit calculates the segregation coefficient through the formula k=(D 单 +D 裂 ) / D 单
