Description

Technical Field

[0001] The present invention relates to the field of machine tool processing, and particularly to the field of pipe cutting. Specifically, it refers to an operation processing method, device, processor and its computer-readable storage medium for eliminating the influence on parts in the case of pulling material slipping. Background Art

[0002] There is a machine tool (i.e., a pulling material machine tool) in the market where the cutting head moves, single-clamp holds, and the length of the pipe to be processed is greater than the stroke of the machine tool. Schematic diagram (such as Figure 2 ), the device on the machine tool that pulls the pipe into the machine tool stroke is called a pulling material fixture. In order to save costs and facilitate control, the pulling material fixture and the cutting head are generally integrated and controlled by the same servo motor to move back and forth.

[0003] The processing steps of the pulling material machine tool are as follows:

[0004] S1: Process the pipe within the current stroke.

[0005] S2: If the next primitive to be processed has a range outside the stroke, "pull" the unprocessed pipe into the machine tool stroke.

[0006] S3: Continue to process the pipe within the current stroke.

[0007] Defect: The prior art adopts the implementation method of the above steps. In the whole processing process, the pulling material action will inevitably occur. Due to the reasons of the pulling material fixture and the pipe, the slipping phenomenon may occur during the pulling material process (see Figure 3 ), resulting in that if there is a pulling material action in the middle part of a part, the length of the part processed in this case will not match the expected length of the part. Summary of the Invention

[0008] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide an operation processing method, device, processor and its computer-readable storage medium for eliminating the influence on parts in the case of pulling material slipping, which has high efficiency, small error and wide application range.

[0009] In order to achieve the above purpose, the operation processing method, device, processor and its computer-readable storage medium for eliminating the influence on parts in the case of pulling material slipping of the present invention are as follows:

[0010] The operation processing method for eliminating the influence on parts in the case of pulling material slipping is mainly characterized in that the method includes the following steps:

[0011] (1) Enable special pulling material processing and select an effective processing area;

[0012] (2) Arrange the parts without sharing edges;

[0013] (3) Judge whether it is necessary to pull the material with the part as a whole. If it is necessary to pull the material, continue to step (4); otherwise, directly process the part.

[0014] (4) Calculate the pulling starting point and pulling distance for the parts that need to be pulled for processing. For the ultra-long parts where the part precision priority strategy cannot take effect, re-classify the primitive elements and judge the pulling with the primitive elements as the unit.

[0015] (5) After the pulling is completed, perform the next round of pulling and processing.

[0016] Preferably, the step (3) specifically includes the following steps:

[0017] (3.1) Judge the part type. If the front end of the pipe is installed outside the effective processing area but within the machine tool stroke, the part type is the part that can be directly processed; if a part of the part exceeds the maximum position of the machine tool stroke, but the length of the whole part is less than or equal to the length of the effective processing area, the part type is the part that needs to be pulled for processing; if a part of the part exceeds the maximum position of the machine tool stroke, and the length of the whole part is greater than the length of the effective processing area, the part type is the ultra-long part where the part precision priority strategy cannot take effect.

[0018] (3.2) If the part type is the part that needs to be pulled for processing or the ultra-long part where the part precision priority strategy cannot take effect, continue to step (4); if the part type is the part that can be directly processed, directly process the part.

[0019] Preferably, the step (4) specifically includes the following steps:

[0020] If the part type is the part that needs to be pulled for processing, calculate the pulling starting point and pulling distance according to the current position of the cutting head and the position of the part that needs to be pulled.

[0021] If the part type is the ultra-long part where the part precision priority strategy cannot take effect, re-classify the primitive elements and judge the pulling with the primitive elements as the unit, and continue to step (3).

[0022] Preferably, the pulling starting point is the processing starting point position of the primitive element to be processed.

[0023] The device for realizing the operation and processing to eliminate the influence of the part on the pulling slip phenomenon is mainly characterized in that the device includes:

[0024] A processor configured to execute computer-executable instructions;

[0025] A memory stores one or more computer-executable instructions. When the computer-executable instructions are executed by the processor, all steps of the above-mentioned operation processing method for eliminating the influence on parts caused by pulling material slippage are implemented.

[0026] The processor for implementing the operation processing for eliminating the influence on parts caused by pulling material slippage is mainly characterized in that the processor is configured to execute computer-executable instructions. When the computer-executable instructions are executed by the processor, all steps of the above-mentioned operation processing method for eliminating the influence on parts caused by pulling material slippage are implemented.

[0027] The computer-readable storage medium is mainly characterized in that a computer program is stored thereon. The computer program can be executed by a processor to implement all steps of the above-mentioned operation processing method for eliminating the influence on parts caused by pulling material slippage.

[0028] By adopting the operation processing method, device, processor and its computer-readable storage medium of the present invention for eliminating the influence on parts caused by pulling material slippage, it is possible to avoid the possible slippage phenomenon in the pulling action of the pulling machine tool, which may cause the length of the part to be inconsistent with the expected length. The present invention ensures a method of not performing a pulling action when processing parts, thereby achieving the effect of transferring the slippage influence to the waste material.

[0033] In order to more clearly describe the technical content of the present invention, the following will be further described in conjunction with specific embodiments.

[0034] Please refer to Figure 4 As shown, the operation processing method of the present invention for eliminating the influence on parts caused by pulling material slippage includes the following steps:

[0035] (1) Enable special pulling material processing and select an effective processing area;

[0036] (2) Arrange the parts in the nesting without sharing a common edge;

[0037] (3) Judge whether material pulling is required with the part as a whole. If material pulling is required, proceed to step (4); otherwise, directly process the part.

[0038] (4) Calculate the material pulling start point and the material pulling distance for the parts that need to be processed after material pulling. For the ultra-long parts where the part precision priority strategy cannot take effect, re-classify the graphic elements and judge material pulling with the graphic elements as the unit.

[0039] (5) After material pulling is completed, perform the next round of material pulling and processing.

[0040] As a preferred embodiment of the present invention, step (3) specifically includes the following steps:

[0041] (3.1) Judge the part type. If the front end of the pipe is installed outside the effective processing area but within the machine tool stroke, the part type is a part that can be directly processed; if a part of the part exceeds the maximum position of the machine tool stroke, but the length of the whole part is less than or equal to the length of the effective processing area, the part type is a part that needs to be processed after material pulling; if a part of the part exceeds the maximum position of the machine tool stroke, and the length of the whole part is greater than the length of the effective processing area, the part type is an ultra-long part where the part precision priority strategy cannot take effect.

[0042] (3.2) If the part type is a part that needs to be processed after material pulling or an ultra-long part where the part precision priority strategy cannot take effect, proceed to step (4); if the part type is a part that can be directly processed, directly process the part.

[0043] As a preferred embodiment of the present invention, step (4) specifically includes the following steps:

[0044] If the part type is a part that needs to be processed after material pulling, calculate the material pulling start point and the material pulling distance according to the current cutting head position and the position of the part that needs to be pulled.

[0045] If the part type is an ultra-long part where the part precision priority strategy cannot take effect, re-classify the graphic elements and judge material pulling with the graphic elements as the unit, and proceed to step (3).

[0046] As a preferred embodiment of the present invention, the material pulling start point is the processing start point position of the graphic element to be processed.

[0047] The device for implementing the operation processing to eliminate the influence of the part on the material pulling slip phenomenon of the present invention, wherein the device includes:

[0048] A processor configured to execute computer-executable instructions;

[0049] A memory stores one or more computer-executable instructions. When the computer-executable instructions are executed by the processor, all steps of the above-mentioned operation processing method for eliminating the influence on parts due to pulling material slippage are implemented.

[0050] The processor of the present invention for implementing the operation processing for eliminating the influence on parts due to pulling material slippage, wherein the processor is configured to execute computer-executable instructions. When the computer-executable instructions are executed by the processor, all steps of the above-mentioned operation processing method for eliminating the influence on parts due to pulling material slippage are implemented.

[0051] The computer-readable storage medium of the present invention stores a computer program thereon. The computer program can be executed by a processor to implement all steps of the above-mentioned operation processing method for eliminating the influence on parts due to pulling material slippage.

[0052] In the specific embodiments of the present invention, since slippage is mainly affected by the pulling fixture and the pipe, the slippage phenomenon cannot be fundamentally avoided. Therefore, there are two solutions:

[0053] (1) Measure the actual distance of slippage and compensate for this distance during each pulling of the material.

[0054] (2) Ensure that the material is not pulled during the processing of a single part, and this part will not be affected by the pulling material slippage.

[0055] For the first solution, due to the differences in the pulling fixture and the pipe, the compensation value is modified according to the actual situation. In theory, the influence of each pulling material slippage can be eliminated, but it is relatively troublesome in actual use. For the second solution, we propose a processing strategy that gives priority to part accuracy. As long as the length of the processed part does not exceed the length of the effective processing area, then it is ensured that the material is not pulled during the processing of this part.

[0056] The pulling processing features of the present invention using the part accuracy priority strategy mainly include the following steps:

[0057] S1, Enable special pulling processing with a reasonable effective processing area.

[0058] The concept of the effective processing area is the section of the distance closest to the rear chuck within the machine tool stroke. It is considered that the processing effect of the pulling machine tool meets the requirements in this area.

[0059] S2, The part nesting is not shared, so there will be waste material, and the influence caused by slippage will be transferred to the waste material.

[0060] S3. Determine whether stock feeding is required for the part as a whole. At this time, the following types of parts will be classified: 1. Parts to be directly processed; 2. Parts that should be processed after stock feeding; 3. Ultra-long parts for which the part precision priority strategy cannot take effect.

[0061] The characteristic of the directly processed part is that the entire primitive is within the machine tool stroke. Currently, the effective processing area is not used for judgment here because when loading the pipe on the machine tool, the front end of the pipe may be loaded outside the effective processing area but within the machine tool stroke. At this time, the pipe should also be processable; the characteristic of the part that requires stock feeding for processing is that a part exceeds the maximum position of the machine tool stroke, but the length of the entire part is less than or equal to the length of the effective processing area. The characteristic of the ultra-long part for which the part precision priority strategy cannot take effect is that a part exceeds the maximum position of the machine tool stroke, and the length of the entire part is greater than the length of the effective processing area.

[0062] S4. If it is a part that requires stock feeding, calculate the stock feeding start point and the stock feeding distance based on the current position of the cutting head and the position of the part that requires stock feeding. If it is an ultra-long part for which the part precision priority strategy cannot take effect, reclassify the primitive and judge stock feeding in units of the primitive.

[0063] The concept of the stock feeding start point is the position where the stock feeding fixture starts to clamp the pipe. For safety and clampability considerations, the selectable range of the stock feeding start point is [the maximum position of the processed primitive, the upper limit of the machine tool]. However, due to efficiency issues, there is an optimal stock feeding start point, which is the processing start point of the primitive to be processed. Therefore, the stock feeding start point should be selected as this optimal start point, or the position closest to the optimal stock feeding start point among the maximum position of the processed primitive and the upper limit of the machine tool.

[0064] The concept of the stock feeding distance is the distance that the stock feeding fixture moves after reaching the stock feeding start point and clamping the pipe. Since it is not in the open light cutting state during stock feeding and the processing effect does not need to be considered, it can move within the entire machine tool stroke. Therefore, as long as the calculated stock feeding distance can prevent the part to be processed from being pulled out of the effective processing area, the maximum can be the entire machine tool stroke, thus ensuring long-distance stock feeding, reducing the number of stock feeding times, and reducing the overall stock feeding processing time.

[0065] S5. After stock feeding is completed, perform a new round of stock feeding processing.

[0066] In a specific embodiment of the present invention, a stock feeding processing method in units of parts is provided to ensure the processing effect and at the same time maximize efficiency. The following takes the stock feeding processing of a pipe with a length of L as an example (when starting to process, the pipe head is just at the upper limit of the machine tool):

[0067] Non - adjacent parts with a processing length of a, the distance between parts is b (greater than the actual slipping distance), and the parts only have vertical cutting lines. A total of n parts can be processed on the pipe (n×a≤L), that is, a total of (2×n) cutting lines need to be processed. The machine tool stroke is Y, and the effective processing area length is E. Since the part length needs to be less than the effective processing area length for the part precision priority strategy to take effect, so a < E is set.

[0068] Due to the material pulling, the situation such as Figure 4 will inevitably occur. When the situation of Figure 4 occurs, the first cutting line of part P2 can be directly processed and then the material is pulled, but the second cutting line of part P2 needs to be processed after pulling the material. If the material is pulled after processing the first cut of P2, then the slipping distance will directly act on the length of part P2, resulting in the length of P2 not matching the expected length, thus scrapping; but when the part precision priority strategy takes effect, the material will be pulled before processing the first cutting line of P2. After pulling the second cutting line of P2 into the effective processing area, then start processing P2. Then the slipping distance will not act on part P2, but on the waste material in front of part P2.

[0069] This case focuses on the field of pipe processing. Starting from the strategy of software controlling the movement of hardware, it does not eliminate the slipping phenomenon. It combines the relationship between parts and waste materials and transfers the actual slipping influence to the waste materials. For example: if the material is pulled once and slips by 5mm less, if the material is pulled once after processing half of the part, then the length of this part will be 5mm shorter. But now it is ensured that the material will only be pulled in the waste material section, so the length of the waste material will be 5mm shorter, and the length of the part will not be affected.

[0070] For a material - pulling machine tool that does not enable the part precision priority strategy, there will always be some parts that are pulled before being completely processed. If there is a slipping phenomenon during the material - pulling action, then the length of this part will surely not match the expected length.

[0071] For the material - pulling processing with the part precision priority strategy enabled, it will judge whether each part can be processed according to the part precision priority strategy. For extra - long parts for which the part precision priority strategy cannot take effect, the software will perform normal material - pulling processing to ensure that the parts can be processed completely. For short parts that will be affected by the material - pulling slip, the material will be pulled directly before processing the whole part. After the material - pulling is completed, then start processing this part. Since there is no material - pulling action when processing this part, the length of this part will not be affected by the material - pulling slip either. In this way, it can be ensured as much as possible that the length of each part is not affected by the material - pulling slip.
