[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0030] With the development of machining technology, an efficient and accurate steam pipe cutting method is needed, such as Figure 1 As shown, Figure 1 The schematic diagram of the process of an embodiment of the steam pipe cutting method provided in the present application includes the following steps:
[0031] Step S11: Place the steam pipe to be cut on the cutting platform, and the positioning device is used to press the steam pipe so that the steam pipe is fixed on the cutting platform; the positioning device can be a clamp or a clamp, which presses the steam pipe tightly from the top or side to make it stable and immovable; fixing the steam pipe can prevent the steam pipe from sliding or shifting during the cutting process, improve the straightness and parallelism of the cutting line, and ensure that the length of each section of the steam pipe after cutting is consistent and meets the specification requirements.
[0032] Step S12: setting the number of cuts of the steam pipe and the material length of the steam pipe; the number of cuts can be flexibly set, suitable for steam pipes of different lengths and different cutting requirements; the tool is controlled to perform even cutting based on the number of cuts of the steam pipe and the material length of the steam pipe, that is, the control unit controls the tool to a preset cutting position to complete the cutting based on the number of cuts of the steam pipe and the material length of the steam pipe, and the tool includes a middle knife, a left knife and a right knife, the middle knife is located in the middle position, and the left knife and the right knife are arranged on both sides of the middle knife; the steps of the control unit controlling the tool to work based on the set parameters are described in detail below:
[0033] The control unit automatically calculates the position of each cutting point according to the input number of cuts and material length. The calculation formula is: the position of each cutting point = material length / number of cuts × (1, 2, ..., number of cuts - 1); the number of cutting points is the number of cuts - 1;
[0034] The control unit adjusts the positions of the middle knife, the left knife and the right knife according to the calculated cutting point position;
[0035] The control unit issues a command to drive the tool to cut according to the predetermined position; after cutting is completed, the tool is reset.
[0036] The specific mode in which the control unit drives the tool is not limited here. For example, if the number of cuts is 3, the control unit determines whether to use the middle knife and the left knife for cutting based on the set parameters. In one embodiment, the control unit drives the middle knife and the left knife to cut at the same time. In another embodiment, the control unit drives the middle knife to cut first, and then controls the left knife to cut after the middle knife has finished cutting.
[0037] The control unit accurately calculates the cutting point position to ensure that the length of each steam pipe after cutting is consistent. Automatic control reduces manual intervention and increases cutting speed. Accurate cutting reduces material waste caused by cutting errors, improves material utilization and reduces costs.
[0038] Step S13: The steam pipe extends along the first direction; the cutter moves along the second direction for cutting; the first direction and the second direction are perpendicular to each other; for example, the first direction is the horizontal direction, and the second direction is the vertical direction; the steam pipe fixed along the first direction is cut in the vertical direction, which can better maintain the stability of the steam pipe and avoid vibration and deviation caused by horizontal movement. After the cutting is completed, the steam pipe after equalization is output, and the staff organizes and stores the steam pipe after cutting.
[0039] The method of fixing the steam pipe along the first direction and moving the tool along the second direction for cutting not only improves the cutting accuracy and efficiency, but also enhances the safety and flexibility of operation, and is suitable for various industrial production and processing scenarios.
[0040] In summary, the steam pipe cutting method of this embodiment includes: placing the steam pipe to be cut on the cutting platform, the positioning device is used to press the steam pipe so that the steam pipe is fixed on the cutting platform; setting the number of cuts of the steam pipe and the material length of the steam pipe; based on the number of cuts of the steam pipe and the material length of the steam pipe, controlling the tool to perform equal cutting, the tool includes a middle knife, a left knife and a right knife; the steam pipe extends along a first direction; the tool moves along a second direction for cutting; the first direction and the second direction are perpendicular to each other; after the cutting is completed, the steam pipe after equal cutting is output. Through the above method, the efficiency and accuracy of the cutting operation are improved, and the high requirements for steam pipe processing in industrial production are met.
[0041] In one embodiment, the left knife and the right knife are symmetrically arranged on both sides of the middle knife; the distance from the left knife to the middle knife is equal to the distance from the right knife to the middle knife; the symmetrically arranged knives can ensure the symmetry and straightness of the cutting line and reduce the cutting error caused by the asymmetry of the knives; the symmetrically arranged knives can perform multi-point cutting at the same time and increase the cutting speed. The symmetrically arranged knives can reduce the unbalanced force generated by the knives during the cutting process and reduce the risk of accidental injury.
[0042] In one embodiment, the material deviation distance is obtained based on the distance sensor, and the material deviation distance is the distance between the leftmost side of the steam pipe and the leftmost side of the cutting platform; the control unit receives the material deviation distance and controls the working state of the tool based on the material deviation distance; the leftmost side of the cutting platform is used as the zero point position, but in the actual installation process, there will be a deviation distance between the leftmost side of the steam pipe and the leftmost side of the cutting platform; for example, the length of the steam pipe is 500mm, and the material deviation distance is 10mm, that is, the distance between the leftmost side of the steam pipe and the leftmost side of the cutting platform is 10mm. If the number of cuts is 2, when the material deviation distance is not considered, the tool is cut at 250mm; if the material deviation distance is considered, the tool is cut at 255mm.
[0043] The distance sensor can accurately measure the material deviation distance to ensure the accuracy of the cutting starting point; the control unit adjusts the cutting point position according to the material deviation distance to avoid cutting errors caused by inaccurate initial position and improve cutting accuracy; the real-time monitoring of the material deviation distance by the distance sensor can timely detect and correct the position deviation to ensure the smoothness and reliability of the cutting process.
[0044] In one embodiment, the moving range of the middle knife is [275mm, 425mm], 275mm is the minimum distance between the middle knife and the leftmost end of the cutting platform, and 425mm is the maximum distance between the middle knife and the leftmost end of the cutting platform; the left knife and the right knife are symmetrically arranged on both sides of the middle knife. If the moving range of the middle knife is not limited, when the knife moves, the left knife and the right knife are easy to collide with the left edge and the right edge of the cutting device.
[0045] Limiting the moving range of the middle knife can prevent the knife from exceeding the effective working area of the cutting platform, reduce vibration and deviation caused by improper position. Limiting the moving range of the middle knife can reduce the risk of collision between the knife and the edge of the cutting platform, and improve operational safety. In this embodiment, the moving range of the middle knife is [275mm, 425mm]. In other embodiments, the moving range of the middle knife can be other values, and no limitation is made to this.
[0046] In one embodiment, if the number of cuts of the steam pipe is set to 3 and two-thirds of the material length of the steam pipe is not greater than 425 mm, the left knife and the middle knife are used to cut the steam pipe; in this embodiment, the right limit distance of the right knife is 637.5 mm. Figure 2 As shown, Figure 2 A schematic diagram of tool distribution in a cutting process according to an embodiment of the present application.
[0047] like Figure 2 As shown, Figure 2 The material length of the steam pipe is 637.5mm, that is, two-thirds of the material length of the steam pipe is 425mm. The left knife and the middle knife are used for cutting. The left knife is located at 212.5mm and the middle knife is located at 425mm, dividing the steam pipe into three equal parts. Since the left knife and the right knife are symmetrically arranged on both sides of the middle knife, the right knife is located at 637.5mm at this time, which is at the limit distance. If two-thirds of the material length of the steam pipe is greater than 425mm but the left knife and the middle knife are still used for cutting, the position of the right knife will exceed the right limit distance and is prone to collide with the right edge of the cutting device.
[0048] If the number of cuts of the steam pipe is set to 3 and two-thirds of the length of the steam pipe material is greater than 425 mm, use the left knife and the right knife to cut the steam pipe. Figure 3 As shown, Figure 3A schematic diagram of tool distribution in a cutting process of another embodiment provided in the present application.
[0049] like Figure 3 As shown, Figure 3 The material length of the steam pipe is 720mm, that is, two-thirds of the material length of the steam pipe is 480mm. Use the left knife and the right knife for cutting. The left knife is located at 240 and the right knife is located at 480mm to divide the steam pipe into three equal parts. Since the left knife and the right knife are symmetrically arranged on both sides of the middle knife, the middle knife is located at 360mm at this time; the right knife is located at 480mm<637.5mm, and the cutting work can be carried out normally.
[0050] Reasonable selection of tool combinations according to different material lengths and the number of cuts can reduce the risk of collision between the tool and the edge of the cutting platform and improve operational safety; it should be made clear that if the number of cuts selected is two, the middle knife is used for cutting, and if the number of cuts is four, the left knife, the middle knife and the right knife are used for cutting. In the actual cutting process, the above cutting process must take into account the material deviation distance.
[0051] In one embodiment, the control unit obtains the number of times the left knife, the middle knife and the right knife are used, respectively, and if the number of uses is greater than a preset number, the knife is replaced; a counter is set in the control unit to record the number of times each knife is used, the control unit obtains the number of times the left knife, the middle knife and the right knife are used, and compares the number of uses with the preset number. If the number of uses is greater than the preset number, the control unit sends a signal to the alarm module, and the alarm module alarms to remind the staff to replace the knife.
[0052] It should be clear that the control unit compares the number of times the left knife, the middle knife and the right knife are used with the preset number of times respectively, and the preset numbers of the three knives can be the same or different; for example, the left knife, the middle knife and the right knife all use the same knife, and the preset number of times is 1000 times. After the number of times used exceeds 1000 times, the control unit sends a signal to the alarm module, and the alarm module alarms. Preferably, in order for the staff to promptly determine which knife has reached the preset number of times, the alarm signals of different knives can be different, and there is no limitation on this.
[0053] Regularly replacing knives can ensure that the knives always remain sharp and avoid cutting quality problems caused by knife wear; regular replacement of knives can reduce tool damage caused by excessive use and extend the service life of the knives and the entire cutting device; sharp knives can reduce resistance during the cutting process, reduce the risk of tool breakage or flying out, and improve operational safety.
