Description

Technical Field

[0001] The present invention relates to the technical field of mechanical engineering, and in particular to a superconducting cavity processing device and a die forging process. Background Art

[0002] Superconducting cavities are the core components of large-scale particle accelerators, primarily converting stored electromagnetic energy into the kinetic energy of charged particles. Niobium is the preferred material for developing superconducting cavities, but various niobium alloys and the exploration and testing of new materials are also research areas.

[0003] Through a large number of case studies, we found that:

[0004] Currently, the basic forming process for superconducting cavities is often stamping or forging. However, this often results in a low pass rate, with the superconducting cavity failing to fully deform plastically and potentially experiencing elastic deformation again after processing, rendering it unusable. This is particularly problematic during the research and development of new alloys and materials. Summary of the Invention

[0016] A die forging process for superconducting cavity processing equipment comprises the following steps:

[0017] S1. Prepare the blank:

[0018] Place the blank in a heating furnace and heat it to 100±5 degrees Celsius to facilitate subsequent forging processing;

[0019] S2. Preparation of special mold for superconducting cavity:

[0020] The lower die, rough forging upper die, fine forging upper die and punching tool of the special die for the superconducting cavity are placed in the working preparation positions respectively; the lower die is placed on the working table of the forging device, and the positioning column is inserted into the positioning hole of the lower die and locked to ensure that the lower die is in a fastened installation state; the rough forging upper die is installed on the turret die automatic switching device, the first lower positioning column is fitted with the positioning port, the upper surface of the first upper template is fitted with the lower surface of the turret arm, the servo motor in the control box works, drives the screw to rotate, drives the movable clamping block to move toward the fixed clamping block, and clamps the first lower positioning column together with the fixed clamping block, thereby clamping the rough forging upper die; the fine forging upper die and the punching tool are also installed on the turret die automatic switching device in the same way, and then the rough forging upper die, fine forging upper die and punching tool are switched through the turret die automatic switching device;

[0021] S3, non-contact cleaning of mold:

[0022] The motor in the base rotates, driving the turret arms and the dies they hold to rotate together via the rotating column. When the rough forging upper die rotates above the first nozzle, the second air compressor in the base starts working, transmitting high-pressure gas through the air pipe column and spraying it upward through the first nozzle, fully blowing away dust and particles on the rough forging upper die. The fine forging upper die and punching tool are also thoroughly cleaned in this way, and the lower die is thoroughly cleaned by the second nozzle.

[0023] S4. Processing preparation:

[0024] The relative position between the turret die automatic switching device and the forging device is determined and the device is in a working preparation state; the heated blank is placed in the working position on the lower die; the turret arm rotates, and the turret arm carrying the punching tool rotates to the bottom of the power head. The third upper positioning column is placed coaxially with the power head, and the upper surface of the third upper positioning column is fixedly connected to the lower surface of the power head through electromagnetic locking. The clamping block is then moved back, the punching tool is released, and the turret arm rotates out of the forging work area;

[0025] S5. Blank punching:

[0026] The hydraulic cylinder in the upper box works, first starting the rapid punching mode, pushing the power head to move downward quickly, driving the punching tool to move downward quickly, punching the blank, and then reset upward. The external manipulator suction cup takes away the punched waste, and the punched circular ring material is obtained.

[0027] S6. Superconducting cavity rough forging:

[0028] The punching ring material is located in the working position on the lower die, the turret arm rotates to the punching tool, the positioning port fits with the lower positioning column, the movable clamping block moves toward the fixed clamping block, squeezing the third lower positioning column, thereby re-clamping the punching tool; at this time, the electromagnetic force is canceled, the power head and the punching tool lose connection, the rotating column rotates to drive the turret arm to rotate, so that the punching tool leaves the working area, and the rough forging upper die comes to the forging working area, and is fixedly connected to the power head in the same way;

[0029] The hydraulic cylinder in the upper box works, starts the slow downward pressure mode, pushes the power head to move slowly downward, drives the rough forging upper die to move slowly downward, squeezes the punched ring material, continues the slow extrusion, makes the punched ring material fully plastically deformed, squeezes to the mold closing state, maintains for 5 minutes, then demolds, and the power head drives the rough forging upper die to reset upward together, at this time the rough forging superconducting cavity is obtained;

[0030] S7, Superconducting Cavity Precision Forging:

[0031] The turret die automatic switching device works in the same way as above. The rough forging upper die is removed and replaced with the fine forging upper die to start the fine forging work.

[0032] The hydraulic cylinder in the upper box works and the slow downward pressure mode is started again, pushing the power head to move slowly downward, driving the fine forging upper die to move slowly downward, squeezing the rough forging superconducting cavity, and continuing the slow squeezing to make the rough forging superconducting cavity further fully plastically deformed and the thickness further compressed, squeezing to the mold closing state, maintaining it for 5 minutes, and then demolding. The power head drives the fine forging upper die to reset upward together, and the fine forging superconducting cavity is obtained at this time;

[0033] S8, superconducting cavity deformation detection;

[0034] The heat-treated precision-forged superconducting cavity is placed on the circular support hole of the superconducting cavity deformation detection device. First, a servo motor drives the screw to rotate, driving the slider to move directly above the circular support hole, with the central axis of the ultrasonic ranging probe aligned with the center of the circular support hole and the central axis of the precision-forged superconducting cavity. The ultrasonic ranging probe then begins operating, emitting ranging ultrasonic waves to every corner of the precision-forged superconducting cavity, thereby obtaining a dense distance data network and storing it in the control box. The device is left to stand for eight hours. After the standstill begins, the ultrasonic ranging probe continues to measure the precision-forged superconducting cavity placed on the circular support hole.

[0035] After standing for eight hours, because the closed-loop servo system has extremely high repeatability, the ultrasonic ranging probe quickly reaches the top of the circular support hole again, and the central axis of the ultrasonic ranging probe is on the same vertical line as the center of the circular support hole and the central axis of the precision-forged superconducting cavity. Then the ultrasonic ranging probe starts working again, emitting ranging ultrasonic waves to every corner of the inner cavity of the precision-forged superconducting cavity, thereby obtaining a dense distance value data network again, storing it in the control box for comparison. If the comparison result shows that the distance values ​​at each point are consistent or the difference is within the allowable range, the precision-forged superconducting cavity is judged to be qualified. Otherwise, the precision-forged superconducting cavity is judged to be unqualified, and unacceptable elastic deformation has occurred. It is necessary to return to S7 and then re-test according to the process steps. If the precision-forged superconducting cavity still fails the test after reprocessing twice, it is judged to be a completely unqualified product and the product scrapping process is changed.

[0036] S9. Scoring and evaluation system analysis records:

[0037] For qualified precision-forged superconducting cavities, some are qualified once, while others require another or two reprocessing cycles. Therefore, a scoring and evaluation method is established to provide a new pass rate assessment method, which in turn provides guidance for the improvement of raw materials and process steps.

[0038] S10, subsequent processing and product molding:

[0039] The qualified precision-forged superconducting cavity is transported to the next link for a series of measures such as machining, surface chemical treatment, etc., and finally undergoes precision welding to form the final superconducting cavity product.

[0040] Beneficial effects of the present invention:

[0041] The superconducting cavity processing equipment and die forging process proposed in the present invention can fully plastically deform and maintain the superconducting cavity with as little elastic deformation as possible, and provide a scoring and evaluation method for the trial production of new materials and new processes, thereby improving product quality. It also has certain guiding significance for the scientific research and testing of new materials and new processes, reducing the production costs of enterprises and improving their efficiency and competitiveness.

[0072] A die forging process for superconducting cavity processing equipment comprises the following steps:

[0073] S1. Prepare the blank:

[0074] The blank 500 is placed in a heating furnace and heated to 100±5 degrees Celsius to facilitate subsequent forging processing;

[0075] S2. Preparation of special mold for superconducting cavity:

[0076] The lower die 301, the rough forging upper die 302, the fine forging upper die 303, and the punching tool 304 of the superconducting cavity special die 300 are placed in the work preparation position respectively; the lower die 301 is placed on the working table of the forging device 200, and the positioning column 3011 is inserted into the positioning hole 2011 of the lower die and locked to ensure that the lower die 301 is in a fastened installation state; the rough forging upper die 302 is installed on the turret type die automatic switching device 100, the first lower positioning column 3022 is fitted with the positioning port 1073, and the upper surface of the first upper template 3023 is aligned with the turret arm 1042 is fitted, the servo motor in the control box 105 works, drives the screw 1071 to rotate, drives the movable clamping block 1072 to move toward the fixed clamping block 1074, and clamps the first lower positioning column 3022 together with the fixed clamping block 1074, thereby clamping the rough forging upper die 302; the fine forging upper die 303 and the punching tool 304 are also installed on the turret die automatic switching device 100, and then the rough forging upper die 302, the fine forging upper die 303 and the punching tool 304 are switched by the turret die automatic switching device 100;

[0077] S3, non-contact cleaning of mold:

[0078] The motor in the base 101 rotates, driving the turret arms and the clamped dies to rotate together through the rotating column 102. When the rough forging upper die 302 rotates to above the first nozzle 1031, the second air compressor in the base 101 starts to work, transmitting high-pressure gas through the air pipe column 103 and spraying it upward through the first nozzle 1031, fully blowing away the dust and particles on the rough forging upper die 302, ensuring dust-free operation in subsequent work processes and preventing the surface of the superconducting cavity from being squeezed by dust and impurities to form tiny pits, which affect product performance. The fine forging upper die 303 and the punching tool 304 are also fully cleaned in this way. The lower die 301 is fully cleaned by the second nozzle 2023.

[0079] S4. Processing preparation:

[0080] The relative position between the turret die automatic switching device 100 and the forging device 200 is determined and in a working preparation state; the heated blank 500 is placed in the working position on the lower die 301; the turret arm rotates, and the turret arm 1041 carrying the punching tool 304 rotates to the bottom of the power head 2022, and the third upper positioning column 3041 is coaxially placed with the power head 2022, and the upper surface of the third upper positioning column 3041 is fixedly connected to the lower surface of the power head 2022 by electromagnetic locking. Then, the clamping block 1062 is moved back, the punching tool 304 is released, and the turret arm rotates out of the forging work area;

[0081] S5. Blank punching:

[0082] The hydraulic cylinder in the upper box 202 works, first starting the rapid punching mode, pushing the power head 2022 to move downward quickly, driving the punching tool 304 to move downward quickly, punching the blank 500, and then reset upward. The external robot suction cup takes away the punched waste, and the punched circular ring material 600 is obtained at this time.

[0083] S6. Superconducting cavity rough forging:

[0084] The punching ring material 600 is located in the working position on the lower die 301, the turret arm 1041 rotates to the punching tool 304, the positioning port 1063 fits with the lower positioning post 3042, and the movable clamping block 1062 moves toward the fixed clamping block 1064, squeezing the third lower positioning post 3042, thereby re-clamping the punching tool 304; at this time, the electromagnetic force is canceled, the power head 2022 loses connection with the punching tool 304, and the rotating column 102 rotates to drive the turret arm to rotate, so that the punching tool 304 leaves the working area, and the rough forging upper die 302 comes to the forging working area and is fixedly connected to the power head 2022 in the same way;

[0085] The hydraulic cylinder in the upper box 202 works, starts the slow pressing mode, pushes the power head 2022 to move slowly downward, drives the rough forging upper die 302 to move slowly downward, squeezes the punched ring material 600, continues the slow squeezing, makes the punched ring material 600 fully plastically deformed, and squeezes it to Figure 12 The mold closing state shown is maintained for 5 minutes, and then demolded, and the power head 2022 drives the rough forging upper mold 302 to reset upward, at which time the rough forging superconducting cavity 700 is obtained;

[0086] S7, Superconducting Cavity Precision Forging:

[0087] The turret type die automatic switching device 100 works in the same way as above. The rough forging upper die 302 is removed and replaced with the fine forging upper die 303 to start the fine forging work.

[0088] The hydraulic cylinder in the upper box 202 works and starts the slow pressing mode again, pushing the power head 2022 to move slowly downward, driving the fine forging upper die 303 to move slowly downward, squeezing the rough forging superconducting cavity 700, and continuing the slow squeezing to make the rough forging superconducting cavity 700 further fully plastically deformed, and the thickness is further compressed, and squeezed to Figure 13 The mold closing state shown is maintained for 5 minutes, and then demolded, and the power head 2022 drives the precision forging upper mold 303 to reset upward, at which time the precision forged superconducting cavity 800 is obtained;

[0089] S8, superconducting cavity deformation detection;

[0090] The heat-treated precision-forged superconducting cavity 800 is placed on the circular supporting hole 4011 of the superconducting cavity deformation detection device 400. First, the servo motor 4031 drives the screw 4032 to rotate, driving the slider 4033 to move directly above the circular supporting hole 4011, and the central axis of the ultrasonic ranging probe 404 is aligned with the center of the circular supporting hole 4011 and the central axis of the precision-forged superconducting cavity 800. Then, the ultrasonic ranging probe 404 starts working, emitting ranging ultrasonic waves to each corner of the inner cavity 801 of the precision-forged superconducting cavity 800, thereby obtaining a relatively dense distance value data network. For example, 1000 points are evenly selected on the entire surface of the inner cavity 801 for distance measurement, and the distance values ​​of the 1000 points are obtained and stored in the control box 405. The device is left to stand for eight hours. After the standstill begins, the ultrasonic ranging probe 404 continues to measure the precision-forged superconducting cavity 800 placed on the circular supporting holes 4012 / 4013 / 4014.

[0091] After standing for eight hours, because the closed-loop servo system has extremely high repeatability, the ultrasonic ranging probe 404 quickly reaches the top of the circular supporting hole 4011 again, and the central axis of the ultrasonic ranging probe 404 and the center of the circular supporting hole 4011 and the central axis of the precision-forged superconducting cavity 800 are all on the same vertical line. Then the ultrasonic ranging probe 404 starts working again, emitting ranging ultrasonic waves to every corner of the inner cavity 801 of the precision-forged superconducting cavity 800, thereby obtaining a relatively dense distance value data network again, storing it in the control box 405, and comparing it. If it is found that the comparison result is that the distance values ​​at each point before and after are consistent or the difference is within the allowable range, then it is determined that the precision-forged superconducting cavity 800 is qualified, has been fully plastically deformed and has no obvious elastic deformation, and can be output to the next link for processing. Otherwise, the precision-forged superconducting cavity 800 will be judged as unqualified, with unacceptable elastic deformation. It is necessary to return to S7 and re-test according to the process steps. If the precision-forged superconducting cavity 800 still fails the test after two re-processings plus the first re-processing, a total of three re-processings, it will be judged as a completely unqualified product and will be scrapped.

[0092] S9. Scoring and evaluation system analysis records:

[0093] For the qualified precision-forged superconducting cavities 800, some are qualified once, while others need to be processed again or twice to be qualified. Therefore, a scoring and evaluation method is established to provide a new pass rate assessment method, which in turn guides the improvement of raw materials and process steps.

[0094] The specific method is as follows: a precision-forged superconducting cavity 800 that is qualified once is scored as 4 points; a precision-forged superconducting cavity 800 that is qualified after reprocessing once is scored as 3 points; a precision-forged superconducting cavity 800 that is qualified after reprocessing twice is scored as 2 points; a precision-forged superconducting cavity 800 that is unqualified and has been scrapped is scored as 1 point; for a certain batch of precision-forged superconducting cavities 800, the total score is divided by the total number of pieces to obtain the value A; when the number of pieces with 4 points accounts for greater than or equal to 50% and A is greater than or equal to 3.1 points, the evaluation is given as good; when the number of pieces with 4 points accounts for greater than or equal to 30% and less than 50% and A is greater than or equal to 2.8 points, the evaluation is given as basically qualified; in other cases, the evaluation is given as poor;

[0095] The above evaluation mechanisms are all automatically executed in the control box 405, and the results are sent to the computer in the workshop control room; they have good guiding significance for the initial successful development of alloy materials, or the initial production testing of new materials and new processes.
