Description

Technical Field

[0001] This invention relates to the field of pipe cutting technology, and more particularly to the field of drawing machine technology, specifically to a method, apparatus, processor, and computer-readable storage medium for drawing machine to achieve ultra-short tail material design. Background Technology

[0002] There is a type of machine tool on the market that uses a moving cutting head, a single clamping mechanism, and handles pipes longer than the machine's travel length (i.e., a material handling machine). For example... Figure 2 As shown, the device on the machine tool that pulls the tube into the machine tool's stroke is called a material pulling clamp. To save costs and facilitate control, the material pulling clamp and the cutting head are usually integrated and controlled by the same servo motor for forward and backward movement.

[0003] Based on the relative positions of the chuck, cutting head, and material handling clamp, material handling machines can be further divided into two categories: one is a machine with the material handling clamp between the chuck and the cutting head, which we call a machine with the clamp on the left (the machine with the clamp directly below the cutting head also belongs to this category); the other is a machine with the cutting head between the chuck and the material handling clamp, which we call a machine with the clamp on the right.

[0004] Machine tools with chucks on the left can directly clamp the pipe after it has been cut, pulling the unprocessed pipe into the processing area. However, because the chucks are between the cutting head and the chuck, a long section of the pipe ends will remain unprocessed (i.e., a long tail).

[0005] Machine tools with chucks on the right (see) Figure 3 There are no other devices between the cutting head and the chuck, which ensures a relatively short tail length (see...). Figure 4 However, this type of machine tool cannot directly clamp the pipe after it has been cut.

[0006] To address this, existing technologies employ a material handling machine structure with the chuck on the right side to achieve shorter tail lengths. This results in the inability to directly clamp the pipe after cutting (see...). Figure 5 ). Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a material pulling machine tool with the chuck on the right side, which can directly clamp the pipe after cutting, and a method, device, processor and computer-readable storage medium for achieving ultra-short tail material design for the material pulling machine tool.

[0008] To achieve the above objectives, the present invention provides a method, apparatus, processor, and computer-readable storage medium for designing ultra-short tail material for drawing machines, as follows:

[0009] The main feature of this method for achieving ultra-short tail material design for drawing machines is that the method includes the following steps:

[0010] (1) After the pipe is cut, the actual position of the effective processing area of ​​the pulling machine is identified according to the effective processing area length parameter and the machine stroke set by the pulling machine.

[0011] (2) Calculate the processing position that the cutting head needs to process based on the graphic elements / parts that need to be processed;

[0012] (3) After the corresponding graphic element / part is processed, determine whether the material pulling machine tool still retains at least one material pulling clamping length in the effective processing area;

[0013] (4) For the graphic elements / parts that need to be pulled, calculate the starting point and pulling distance based on the current cutting head position and the position of the graphic elements / parts that need to be pulled;

[0014] (5) After the material pulling is completed, a new round of material pulling processing will be carried out.

[0015] Preferably, the effective processing area specifically refers to:

[0016] The distance within the machine tool stroke of the aforementioned material pulling machine to the closest point to the rear chuck.

[0017] Preferably, step (3) specifically includes:

[0018] The processed elements / parts include: elements / parts that can be directly processed; elements / parts that require material pulling for processing; and extra-long elements / parts that cannot be processed.

[0019] Specifically, the direct processing of the drawing element / part means that the entire drawing element / part is within the machine tool stroke, and the maximum position is at least one pulling and clamping length away from the upper limit of the machine tool.

[0020] The graphic element / part that requires material pulling is specifically defined as follows: the maximum position is greater than the difference between the machine tool limit and the material pulling clamping length, and the length of the entire graphic element / part is less than or equal to the effective processing area length minus the material pulling clamping length;

[0021] The aforementioned unprocessable ultra-long graphic elements / parts are specifically defined as follows: the maximum position is greater than the difference between the machine tool's minimum material pulling and clamping length, and the length of the entire graphic element / part is greater than the effective processing area length minus the material pulling and clamping length.

[0022] Preferably, the graphic elements / parts requiring material pulling are specifically:

[0023] Elements / parts for which the length cannot be left for clamping during material pulling, but can be left for length after processing.

[0024] Preferably, the starting point for material pulling is specifically:

[0025] The initial clamping position of the material pulling fixture on the tube, and the range of the material pulling starting point selection is [maximum position of the machined graphic element / part + material pulling clamping length, upper limit of the machine tool].

[0026] Preferably, the pulling distance is specifically:

[0027] After the material pulling fixture moves to the starting point of the material pulling, it clamps the tube and moves a distance thereafter; and the material pulling distance is: the maximum material pulling distance is the entire machine tool stroke before the graphic element / part to be processed is pulled out of the effective processing area.

[0028] The main feature of this device designed for achieving ultra-short tail lengths on drawing machines is that the device includes:

[0029] A processor is configured to execute computer-executable instructions;

[0030] The memory stores one or more computer-executable instructions, which, when executed by the processor, implement the steps of the method described above for designing ultra-short tail stock for a drawing machine.

[0031] The processor for implementing ultra-short tail material design for drawing machines is characterized in that the processor is configured to execute computer-executable instructions, which, when executed by the processor, implement the various steps of the method for implementing ultra-short tail material design for drawing machines described above.

[0032] The main feature of this computer-readable storage medium is that it stores a computer program thereon, which can be executed by a processor to implement the various steps of the method described above for designing ultra-short tail material for a drawing machine.

[0033] The present invention employs a method, apparatus, processor, and computer-readable storage medium for designing ultra-short tail material for a material pulling machine. Each graphic element to be processed is differentiated, and graphic elements that cannot be processed by such a machine are identified and the user is notified that they cannot be processed. Machinable graphic elements that cannot leave sufficient pulling and clamping length after processing are identified, and material is pulled in advance to ensure sufficient pulling and clamping length after processing. All pulling actions ensure that the material moves forward at least one pulling and clamping length before clamping the tube, thereby achieving the effect that the machine tool with the short tail material chuck on the right can normally pull and process the material.

[0042] To more clearly describe the technical content of the present invention, the following description is provided in conjunction with specific embodiments.

[0043] Before describing the embodiments of the present invention in detail, it should be noted that, in the following, the terms “comprising,” “including,” or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0044] This method for achieving ultra-short tail material design for drawing machines includes the following steps:

[0045] (1) After the pipe is cut, the actual position of the effective processing area of ​​the pulling machine is identified according to the effective processing area length parameter and the machine stroke set by the pulling machine.

[0046] (2) Calculate the processing position that the cutting head needs to process based on the graphic elements / parts that need to be processed;

[0047] (3) After the corresponding graphic element / part is processed, determine whether the material pulling machine tool still retains at least one material pulling clamping length in the effective processing area;

[0048] (4) For the graphic elements / parts that need to be pulled, calculate the starting point and pulling distance based on the current cutting head position and the position of the graphic elements / parts that need to be pulled;

[0049] (5) After the material pulling is completed, a new round of material pulling processing will be carried out.

[0050] In a preferred embodiment of the present invention, the effective processing area specifically refers to:

[0051] The distance within the machine tool stroke of the aforementioned material pulling machine to the closest point to the rear chuck.

[0052] In a preferred embodiment of the present invention, step (3) specifically comprises:

[0053] The processed elements / parts include: elements / parts that can be directly processed; elements / parts that require material pulling for processing; and extra-long elements / parts that cannot be processed.

[0054] Specifically, the direct processing of the drawing element / part means that the entire drawing element / part is within the machine tool stroke, and the maximum position is at least one pulling and clamping length away from the upper limit of the machine tool.

[0055] The graphic element / part that requires material pulling is specifically defined as follows: the maximum position is greater than the difference between the machine tool limit and the material pulling clamping length, and the length of the entire graphic element / part is less than or equal to the effective processing area length minus the material pulling clamping length;

[0056] The aforementioned unprocessable ultra-long graphic elements / parts are specifically defined as follows: the maximum position is greater than the difference between the machine tool's minimum material pulling and clamping length, and the length of the entire graphic element / part is greater than the effective processing area length minus the material pulling and clamping length.

[0057] In a preferred embodiment of the present invention, the graphic element / part requiring material drawing processing is specifically:

[0058] Elements / parts for which the length cannot be left for clamping during material pulling, but can be left for length after processing.

[0059] In a preferred embodiment of the present invention, the starting point for material pulling is specifically:

[0060] The initial clamping position of the material pulling fixture on the tube, and the range of the material pulling starting point selection is [maximum position of the machined graphic element / part + material pulling clamping length, upper limit of the machine tool].

[0061] In a preferred embodiment of the present invention, the material pulling distance is specifically as follows:

[0062] After the material pulling fixture moves to the starting point of the material pulling, it clamps the tube and moves a distance thereafter; and the material pulling distance is: the maximum material pulling distance is the entire machine tool stroke before the graphic element / part to be processed is pulled out of the effective processing area.

[0063] In practical applications, this technical solution provides a method where, after pipe cutting, the pulling clamp moves forward to a position where it can clamp the pipe before clamping it, thus solving the problem that pulling machine tools with the chuck on the right cannot directly clamp the pipe after cutting. This achieves the effect of normal material pulling and processing even for machine tool structures with shorter tail materials.

[0064] In practical applications, to ensure that machine tools with the chuck on the right can still perform material handling, the relative distance between the cutting head and the material handling clamp needs to be measured (see...). Figure 6 This refers to the material pulling clamping length. For machine tools with the chuck on the left, this is not necessary, and the material pulling clamping length is uniformly set to 0. After cutting the graphic element or part, the material pulling clamp only needs to move at least one material pulling clamping length in the unprocessed direction to ensure that the material pulling clamp can clamp the tube material. Therefore, it is necessary to ensure that there is still one material pulling clamping length that can move after the graphic element or part is processed during the material pulling process.

[0065] The drawing process feature using the drawing clamping length parameter mainly includes the following steps:

[0066] S1 identifies the actual position of the effective machining area based on the set effective machining area length parameters and machine tool travel.

[0067] S2 calculates the graphic elements / parts that need to be processed, and the location where the cutting head needs to be processed.

[0068] S3 determines whether at least one clamping length can be left within the effective machining area after machining this graphic element / part. At this time, the graphic elements will be divided into the following categories: 1. Directly machined graphic elements; 2. Graphic elements that cannot leave a clamping length for pulling, but can leave a length after pulling and machining; 3. Unmachined extra-long graphic elements.

[0069] The concept of the effective machining area is the shortest distance within the machine tool's travel from the chuck. It is believed that the machining effect of the pull-out machine tool meets the requirements within this area.

[0070] The characteristic of directly machinable elements is that the entire element is within the machine tool travel (but the maximum position is at least one pull-and-clamp length away from the upper limit of the machine tool). Currently, the effective machining area is not used for judgment, because when loading the pipe onto the machine tool, the very tip of the pipe may be outside the effective machining area but still within the machine tool travel; in this case, the pipe should still be machinable. The characteristic of elements that require pull-and-clamp to be machinable is that the maximum position is greater than the difference between the upper limit of the machine tool and the pull-and-clamp length, but the length of the entire element is less than or equal to the effective machining area length minus the pull-and-clamp length. The characteristic of unmachinable, excessively long elements is that the maximum position is greater than the difference between the upper limit of the machine tool and the pull-and-clamp length, but the length of the entire element is greater than the effective machining area length minus the pull-and-clamp length.

[0071] S4. If the graphic element requires material pulling, calculate the material pulling starting point and material pulling distance based on the current cutting head position and the position of the graphic element requiring material pulling.

[0072] The concept of the material pulling start point is the position where the material pulling fixture begins to clamp the pipe. For safety and clamping considerations, the range of the material pulling start point can be selected as [maximum position of the processed element + material pulling clamping length, upper limit of the machine tool]. However, due to efficiency issues, there exists an optimal material pulling start point, which is the starting position of the processing of the element to be processed.

[0073] The concept of material pulling distance is the distance the material pulling fixture travels after reaching the starting point and clamping the tube. Since the material pulling process is not in a cutting state and the processing effect does not need to be considered, it can move within the entire machine tool stroke. Therefore, the calculated material pulling distance can be the entire machine tool stroke as long as it does not pull the graphic element to be processed out of the effective processing area. This ensures that long-distance material pulling is possible, reducing the number of material pulling operations and the overall material pulling processing time.

[0074] S5, after the material pulling is completed, a new round of material pulling processing will be carried out.

[0075] This technical solution describes a method for designing ultra-short tail material for a material pulling machine, which can achieve the goal of leaving only a short tail material while still enabling normal material pulling and processing.

[0076] In one specific embodiment of the present invention, the following example is taken when drawing and processing a tube of length L (the tube end is just at the limit of the machine tool at the beginning of processing):

[0077] There are non-common side parts with a length of 'a', and a spacing of 'b' between them. Each part has only a vertical cut-off line. A total of n parts (n*a≤L) can be machined on the pipe, meaning there are a total of (2*n) cut-off lines to be machined. The machine tool travel is Y, the effective machining area length is E, and the material clamping length is C.

[0078] The machine tool with the chuck on the right side is mainly... Figure 8 The situation shown requires special handling:

[0079] When this situation occurs, if the second cut-off line of part P1 is cut first, subsequent elements cannot be pulled into the effective processing area unless they can be processed without material pulling. Therefore, material pulling should be performed before the second cut-off line of part P1 is cut. This invention first determines whether all subsequent elements can be processed without material pulling. If not, it determines the size of the maximum position of the element and the position of (machine tool limit - C). If the maximum position of the element is greater than the position of (machine tool limit - C), the software will control the fixture to start pulling material at the clamping position before processing this element, thereby ensuring that the machine tool can pull material normally.

[0080] This device, designed for achieving ultra-short tail lengths on drawing machines, includes:

[0081] A processor is configured to execute computer-executable instructions;

[0082] The memory stores one or more computer-executable instructions, which, when executed by the processor, implement the steps of the method described above for designing ultra-short tail stock for a drawing machine.

[0083] The processor for implementing ultra-short tail material design for drawing machines is characterized in that the processor is configured to execute computer-executable instructions, which, when executed by the processor, implement the various steps of the method for implementing ultra-short tail material design for drawing machines described above.

[0084] The main feature of this computer-readable storage medium is that it stores a computer program thereon, which can be executed by a processor to implement the various steps of the method described above for designing ultra-short tail material for a drawing machine.

[0085] Any process or method description in the flowchart or otherwise herein can be understood as representing a module, segment, or portion of code comprising one or more executable instructions for implementing a particular logical function or process, and the scope of the preferred embodiments of the invention includes additional implementations in which functions may be performed not in the order shown or discussed, including substantially simultaneously or in reverse order depending on the functions involved, as will be understood by those skilled in the art to which embodiments of the invention pertain.

[0086] It should be understood that various parts of the present invention can be implemented using hardware, software, firmware, or a combination thereof. In the above embodiments, multiple steps or methods can be implemented using software or firmware stored in memory and executed by a suitable instruction execution device.

[0089] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "embodiment," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0090] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0091] For machine tools with the chuck on the right, if the material is not pulled forward by at least one pulling clamping length after cutting, the pipe will not be clamped tightly. However, if the material is simply pulled forward by at least one pulling clamping length before each pull, after some elements are processed, there is not enough time for the pulling clamp to move forward by one pulling clamping length, and processing will stop because the movement exceeds the machine tool's travel. The present invention, which uses a method, device, processor, and computer-readable storage medium for designing ultra-short tail material for pulling machine tools, distinguishes each element that needs to be processed, identifies elements that cannot be processed by such machine tools and prompts the user that they cannot be processed, identifies processable elements that cannot leave enough pulling clamping length after processing, and pulls the material in advance to ensure that enough pulling clamping length can be left after processing. All pulling actions ensure that the material is pulled forward by at least one pulling clamping length before clamping the pipe, thereby achieving the effect of normal material pulling and processing for machine tools with short tail material and chucks on the right.

[0092] In this specification, the invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and variations can be made without departing from the spirit and scope of the invention. Therefore, the specification and drawings should be considered illustrative rather than restrictive.
