[0002] The cladding tube is a tubular component used to wrap nuclear fuel in a nuclear reactor. It is usually made of materials with good high temperature resistance, corrosion resistance, and radiation resistance, such as zirconium alloy.

It can prevent corrosion and leakage of nuclear fuel, take away heat, maintain the normal operating temperature of the reactor, and ensure the safe operation of the reactor.

[0060] S4: When it is detected that the cladding tube raw material is pushed to the machine tool cutting center on the cladding tube cutting platform, the single-axis CNC lathe and the double-axis CNC lathe are driven to execute cutting instructions corresponding to the cutting control strategy for each cladding tube raw material.

[0061] It should be noted that in the manufacturing process of nuclear fuel assemblies, long cladding tubes need to be cut into short tubes of a certain length in order to be assembled into nuclear fuel assemblies. This process requires high cutting accuracy of the cladding tubes to ensure the dimensional accuracy and quality stability of the nuclear fuel assemblies. The traditional cladding tube cutting process is manually operated, which consumes manpower for loading and unloading, has high labor intensity, low work efficiency, and the production process parameters cannot be controlled, and cannot match the corresponding cycle time of the workshop capacity. In order to solve the above problems, this embodiment drives the loading mechanism to move the cladding tube raw material to the cladding tube cutting platform, and then generates a cutting control strategy including a pushing instruction and a cutting instruction for the first cutting end, a second cutting moving distance, a pushing instruction and a cutting instruction for the second cutting end according to the measured first cutting movement distance and the cutting target length of the target batch, and sends them to the single-axis CNC lathe and the double-axis CNC lathe at the two ends of the cladding tube cutting platform respectively, so that the cladding tube raw material can perform independent cutting tasks at the first cutting end and the second cutting end respectively, and proposes a cutting strategy that adapts to different cutting length requirements, reduces the moving distance of the cladding tube raw material, avoids transportation damage, and can also accurately calculate the pushing distance in the automated cutting process, while maximizing the cutting efficiency and ensuring good cutting accuracy.

[0062] In a preferred embodiment, the step of loading the target batch of cladding tube raw materials onto the stocking rack specifically includes:

[0063] S11: The user manually loads the target batch of cladding tube raw materials to the stock rack. When the full material detection sensor on the stock rack detects that the cladding tube raw materials meet the full material condition, a loading alarm signal is triggered to stop manual loading;

[0064] S12: Obtaining a cutting task of a target batch of cladding tube raw materials input by a user in the control system, and extracting a cutting target length of each cladding tube raw material in the cutting task.

[0065] On this basis, the feeding mechanism includes a transverse material moving and lifting device and a longitudinal material moving device arranged on the cladding tube cutting platform; the step of driving the feeding mechanism to move the cladding tube raw materials on the storage rack to the cladding tube cutting platform specifically includes:

[0066] S13: When receiving a processing start signal input by the user in the control system, the lateral material moving and lifting device is driven to move the cladding tube raw materials on the material storage rack to the cladding tube cutting platform;

[0067] S14: The longitudinal material transfer device on the cladding tube cutting platform receives the cladding tube raw material transferred by the transverse material transfer and lifting device.

[0068] In this embodiment, the target batch of cladding tube raw materials are first loaded into the stocking rack manually, the target cutting length of each cladding tube raw material in the cutting task of the target batch of cladding tube raw materials is extracted, and then the cladding tube raw materials on the stocking rack are moved to the longitudinal material moving device on the cladding tube cutting platform by using the lateral material moving and lifting device in the loading mechanism. It should be noted that the lateral material moving and lifting device is configured to have a lifting mechanism and a stocking tray, the lifting mechanism is used to lift the stocking tray, drive the stocking tray to tilt slightly toward one side of the longitudinal material moving device, so that the cladding tube raw materials on the stocking tray are slowly moved to the longitudinal material moving device after the blocking structure is retracted, and the longitudinal material moving device is provided with a moving part detection device and a pushing mechanism, which are used to detect the position of the cladding tube raw materials on the longitudinal material moving device (i.e., the distance from the two ends) and push the cladding tube raw materials into the single-axis CNC lathe and the double-axis CNC lathe arranged at the two ends, so as to realize the subsequent cutting process of the first cutting end and the second cutting end.

[0069] In a preferred embodiment, Figure 2 As shown, the step of measuring the first cutting moving distance by using a length measuring device specifically includes:

[0070] S21: driving the mover detection devices on both sides of the longitudinal material moving device to use a contact measurement sensor to measure a first distance L1 between the pusher mechanism at the first cutting end of the cladding tube cutting platform and the cladding tube raw material, and determining the cutting target length in the cutting task as a second distance L2;

[0071] S22: determining the overall length of the longitudinal material moving device as a third distance L3, and determining the preset end waste length of the cladding tube raw material as a fourth distance L4;

[0072] S23: Determine the actual value of the first cutting moving distance according to the calculation formula of the first cutting moving distance, wherein the calculation formula of the first cutting moving distance is specifically:

[0073] L = L3 - L1 - L2 + L4;

[0074] Wherein, L represents the actual value of the first cutting moving distance.

[0075] On this basis, based on the first cutting moving distance and the cutting target length of the target batch, a cutting control strategy step is generated, specifically:

[0076] S24: Obtain the raw material length of the target batch of cladding tubes, and based on the raw material length of the cladding tubes, the first cutting moving distance and the target cutting length of the target batch, take the length of the cut cladding tubes obtained in each cutting as the target cutting length, generate a pushing instruction and a cutting instruction for the first cutting end;

[0077] S25: Based on the pushing instruction and cutting instruction of the first cutting end and the cutting target length of the target batch, the length of the cut cladding tube obtained in each cutting is used as the cutting target length, and the second cutting moving distance and the pushing instruction and cutting instruction of the second cutting end are generated.

[0078] In this embodiment, after the cladding tube raw material is moved to the longitudinal material moving device, the first distance L1 between the pushing mechanism of the first cutting end of the cladding tube cutting platform and the cladding tube raw material is measured by the contact measuring sensor through the moving detection device, and then the first cutting moving distance (i.e., the moving distance between the initial position of the cladding tube raw material on the longitudinal material moving device and the position where the waste material is cut) is calculated according to the known second distance L2, the third distance L3 and the fourth distance L4. After the first cutting moving distance is calculated, according to the length of the cladding tube raw material and the cutting target length of the target batch, the length of the cut cladding tube obtained each time is used as the cutting target length as the target, and the pushing instruction and cutting instruction of the first cutting end are generated (i.e., the pushing instruction and cutting instruction are executed in sequence to complete the execution of the cyclic action of pushing and cutting). After that, according to the remaining cladding tube raw material after executing the pushing instruction and cutting instruction of the first cutting end, the length of the cut cladding tube obtained each time is used as the cutting target length as the target, and the second cutting moving distance and the pushing instruction and cutting instruction of the second cutting end are generated, so as to improve the automation and intelligence of the cladding tube cutting process.

[0079] In a preferred embodiment, the target batch of cladding tube raw materials is configured to include a long tube cutting task, and the long tube cutting task is configured so that the number of long tubes obtained by cutting the target length of the cladding tube raw materials of the target batch after deducting the preset end waste lengths at both ends is not greater than 1;

[0080] Based on the first cutting moving distance and the cutting target length of the target batch, a cutting control strategy step is generated, specifically comprising:

[0081] S241: Obtain the raw material length of the target batch of cladding tubes, and based on the raw material length of the cladding tubes, the first cutting moving distance and the target cutting length of the target batch, take the length of the cut cladding tubes obtained in each cutting as the target cutting length, generate a material pushing instruction and a cutting instruction for the first cutting end;

[0082] Wherein, the pushing instruction and cutting instruction of the first cutting end include: a pushing instruction and a cutting instruction for cutting the waste material of a preset end at a time;

[0083] S251: Based on the pushing instruction and cutting instruction of the first cutting end and the cutting target length of the target batch, the length of the cut cladding tube obtained in each cutting is taken as the cutting target length, and the second cutting moving distance and the pushing instruction and cutting instruction of the second cutting end are generated;

[0084] Wherein, the pushing instruction and cutting instruction of the second cutting end include: a pushing instruction and cutting instruction for cutting the waste material at a preset end length and a pushing instruction and cutting instruction for cutting a target length.

[0085] In this embodiment, the target batch of cladding tube raw materials is configured to include a long tube cutting task, and the long tube cutting task is configured so that the number of long tubes obtained by cutting the target length of the cladding tube raw materials after deducting the preset end waste lengths at both ends is not greater than 1 (that is, the length of the cladding tube raw materials can only be cut into one long tube). Considering that when executing the long tube cutting task, if only a lathe at one end is used to perform the cutting action, on the one hand, the cladding tube raw materials need to be longitudinally moved a long distance on the longitudinal material moving device or the cutting direction needs to be changed. Both of these practices will greatly reduce the efficiency of the cladding tube cutting process. On the other hand, the long distance movement and the change of the cutting direction will lead to inaccurate positioning of the cladding tube raw materials and the occurrence of wear and damage, etc., affecting the quality of the finished product. Therefore, in this embodiment, a dual-axis CNC machine tool and a single-axis CNC machine tool are respectively arranged at both ends of the longitudinal material moving device, and the dual-axis CNC machine tool at the first end is used to perform the waste cutting and cutting tasks of the target cutting length at one end of the cladding tube raw material, and the single-axis CNC machine tool at the second end is used to perform the waste cutting and cutting tasks of the target cutting length at the other end of the cladding tube raw material, thereby improving the cladding tube cutting processing efficiency and also improving the quality of the processed products.

[0086] In a preferred embodiment, the target batch of cladding tube raw materials is configured to include a short tube cutting task, wherein the short tube cutting task is configured such that the number of long tubes obtained by cutting the target length of the cladding tube raw materials of the target batch after deducting the preset end waste lengths at both ends is greater than 1;

[0087] Based on the first cutting moving distance and the cutting target length of the target batch, a cutting control strategy step is generated, specifically comprising:

[0088] S242: Obtain the raw material length of the target batch of cladding tubes, and based on the raw material length of the cladding tubes, the first cutting moving distance, and the target cutting length of the target batch, take the length of the cut cladding tubes obtained in each cutting as the target cutting length, generate a material pushing instruction and a cutting instruction for the first cutting end;

[0089] Wherein, the pushing instruction and cutting instruction of the first cutting end include: a pushing instruction and cutting instruction for cutting a preset end waste length and a plurality of pushing instructions and cutting instructions with a target cutting length as the target, until the remaining cladding tube raw material length does not meet the sum of the target cutting length and the preset end waste length;

[0090] S252: Generate a second cutting moving distance and a pushing instruction and a cutting instruction of a second cutting end; wherein the pushing instruction and the cutting instruction of the second cutting end are configured as empty instructions.

[0091] In this embodiment, the target batch of cladding tube raw materials is configured to include a short tube cutting task, and the short tube cutting task is configured so that the number of long tubes obtained by cutting the target length of the cladding tube raw materials of the target batch after deducting the preset end waste lengths at both ends is greater than 1 (that is, the length of the cladding tube raw materials can be cut into multiple short tubes). Considering that when executing the short tube cutting task, the use of a dual-axis CNC machine tool to perform the cutting action has a higher execution efficiency, and there is no need to move long distances and change the cutting direction, therefore, this embodiment can achieve the waste cutting and cutting tasks of the first cutting end and the pushing cutting tasks of the cutting target length and the waste cutting and the pushing cutting tasks of the cutting target length at the second cutting end only by setting the dual-axis CNC machine tool at one end of the longitudinal material moving device, thereby realizing the generation and distribution of different cutting strategies for different cladding tube cutting processing requirements.

[0092] In a preferred embodiment, the dual-axis CNC lathe is configured as the first cutting end of the cladding tube cutting platform, and the single-axis CNC lathe is configured as the second cutting end of the cladding tube cutting platform;

[0093] The pushing instruction of the first cutting end drives the pushing mechanism to push the cladding tube raw material on the cladding tube cutting platform to the dual-axis CNC lathe. When it is detected that the cladding tube raw material is pushed to the machine tool cutting center of the dual-axis CNC lathe on the cladding tube cutting platform, the dual-axis CNC lathe is driven in sequence to execute the cutting task of the first cutting end and the pushing instruction of the subsequent pushing mechanism;

[0094] Among them, the pushing instruction of the second cutting end drives the pushing mechanism to push the cladding tube raw material on the cladding tube cutting platform to the single-axis CNC lathe. When it is detected that the cladding tube raw material is pushed to the machine tool cutting center of the single-axis CNC lathe on the cladding tube cutting platform, the single-axis CNC lathe is driven in sequence to execute the cutting task of the second cutting end and the pushing instructions of the subsequent pushing mechanism.

[0095] In this embodiment, a dual-axis CNC lathe is arranged at the first cutting end, so that the control system sequentially drives the dual-axis CNC lathe to execute the cutting task of the first cutting end and the pushing instructions of the subsequent pushing mechanism, and a single-axis CNC lathe is arranged at the second cutting end, so that the control system sequentially drives the single-axis CNC lathe to execute the cutting task of the second cutting end and the pushing instructions of the subsequent pushing mechanism, thereby realizing the generation and allocation of different cutting strategies for different cladding tube cutting processing requirements.

[0096] In a preferred embodiment, the first cutting moving distance is measured by a length measuring device, and based on the first cutting moving distance and the cutting target length of the target batch, a cutting control strategy step is generated, which further includes: driving a visual recognition device on the longitudinal material moving device to recognize an identification code on the cladding tube raw material, and using the identification code to determine a diameter-changing area on the cladding tube raw material;

[0097] Based on the first cutting moving distance and the cutting target length of the target batch, a cutting control strategy step is generated, specifically:

[0098] S243: Obtain the raw material length of the target batch of cladding tubes, and based on the raw material length of the cladding tubes, the first cutting moving distance and the target cutting length of the target batch, take the length of the cut cladding tubes obtained in each cutting as the target cutting length, take the variable diameter area as the middle waste area as a constraint, and generate the pushing instruction and cutting instruction of the first cutting end;

[0099] S253: Based on the pushing instruction and cutting instruction of the first cutting end and the cutting target length of the target batch, the length of the cut cladding tube obtained in each cutting is used as the cutting target length, and the variable diameter area is used as the middle waste area as a constraint to generate the second cutting moving distance and the pushing instruction and cutting instruction of the second cutting end.

[0100] In this embodiment, taking into account the possible diameter change scenarios of the cladding tube raw materials, the identification code on the cladding tube raw materials is identified by a visual recognition device, and the diameter change area on the cladding tube raw materials is located. Then, when generating a cutting control strategy, the diameter change area is used as the middle waste area of ​​the cladding tube raw materials. Then, when generating the pushing instructions and cutting instructions of the first cutting end and the pushing instructions and cutting instructions of the second cutting end, the middle waste area is considered to be eliminated, and a cutting control strategy that adapts to the actual situation of the cladding tube is generated, thereby improving the automation and intelligence of the cladding tube cutting process and avoiding the influence of different cladding tube raw materials.
