Description

Technical Field

[0001] The present application relates to the technical field of impact sample processing, and in particular to a processing system, a processing method and a preparation method of a radioactive impact sample. Background Art

[0002] In Charpy impact tests on metal materials, metal specimens typically break at the notch after impact, resulting in two broken specimen ends. To fully utilize radioactive impact specimens, radioactive impact specimen reconstruction technology can be used to regenerate new radioactive impact specimens.

[0003] Radioactive impact sample reconstruction technology involves reassembling the broken ends of previously tested radioactive impact samples to form a specimen blank, which is then processed into a radioactive impact sample for retesting. This technology can significantly improve the efficiency of impact sample use and obtain more impact test data. However, current radioactive impact sample reconstruction technology has many shortcomings. Summary of the Invention

[0008] In a second aspect, an embodiment of the present application further provides a method for processing a radioactive shock sample, wherein the processing method utilizes the processing system of the first aspect of the present application to process a blank of the radioactive shock sample formed by welding to form a radioactive shock sample.

[0042] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. For the sake of clarity and conciseness, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the process of developing any such actual implementation in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and these constraints may vary depending on the implementation. In addition, it should be understood that although the development work may be very complex and time-consuming, it is a routine task for those skilled in the art who benefit from the content of this application.

[0043] It is also necessary to explain here that, in order to avoid obscuring the present application due to unnecessary details, the accompanying drawings only show the device structure and / or processing steps that are closely related to the solution according to the present application, while other details that are not closely related to the present application are omitted.

[0044] It should be noted that, unless otherwise defined, the technical or scientific terms used in this application should have the common meanings understood by persons having ordinary skills in the field to which this application belongs.

[0045] In the description of the embodiments of the present application, “multiple” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0046] An embodiment of the present application provides a radioactive impact sample processing system for processing a welded radioactive impact sample blank. The blank may include a central main section and two end sections welded to the main section at either end. The main section is radioactive and is formed by cutting the radioactive impact sample. Specifically, the main section is formed by cutting off the two ends of the radioactive impact sample blank.

[0047] The material of the end splice is similar in properties to the radioactive main body, ensuring that the properties of the reconstructed radioactive impact specimen are as close as possible to those of the original radioactive impact specimen. For example, the end splice can be made of the same material as the main body, but without irradiation and without radioactivity.

[0048] In some embodiments, as Figures 1 to 3As shown, the processing system may include a blank holder 71 , a cutting device 80 and a blank transporter 90 .

[0049] The blank holder 71 can be configured to hold any one of the end sections of the blank 60. For ease of distinction, the two end sections of the blank 60 are referred to as the first end section 621 and the second end section 622. The structures and materials of the first end section 621 and the second end section 622 can be identical.

[0050] Specifically, the blank holder 71 can be configured to hold the first end splicing section 621 of the blank 60. The cutting device 80 can include a cutting auxiliary clamping member 81 and a cutting member 82. The cutting auxiliary clamping member 81 can be configured to clamp the main body section 61 of the blank 60. The blank transporting member 90 can be configured to clamp the second end splicing section 622 of the blank 60 to transfer the blank 60 from the blank holder 71 to the cutting auxiliary clamping member 81. The cutting member 82 is configured to cut the main body section 61, the first end splicing section 621 and the second end splicing section 622 of the blank 60 clamped by the cutting auxiliary clamping member 81 to form a radioactive impact sample.

[0051] In the embodiment of the present application, the blank holder 71 is used to hold the first end joint section 621 of the blank 60, thereby initially positioning the blank 60 so that the blank transporter 90 can clamp the blank 60. Through the interaction between the blank holder 71, the cutting device 80, and the blank transporter 90, the blank 60 formed by welding the radioactive impact sample can be delivered to the cutting device 80 and cut into radioactive impact samples.

[0052] In some embodiments, the cutting device 80 may be a wire-cut electric discharge machine, and the cutting member 82 may be an electrode wire. In some embodiments, the cutting device 80 may be a slow-feed wire-cut electric discharge machine.

[0053] In some embodiments, the electrode wire may be a molybdenum wire having a diameter equal to 0.2 mm.

[0054] In some embodiments, the processing system may include a blank holding platform for mounting the blank holder 71 .

[0055] In some embodiments, the blank holder 71 may include a blank holder body 711 and a plurality of movable members 712 disposed on the blank holder body 711. The plurality of movable members 712 are movably disposed on the blank holder body 711 to collectively hold the blank 60 by abutting against the first end splicing section 621 of the blank 60.

[0056] The embodiment of the present application holds the blank 60 by placing multiple moving parts 712 arranged on the blank holding body 711 in contact with the first end splicing section 621 of the blank 60, so that the clamped blank 60 is not prone to shaking, and at the same time facilitates the blank transfer part 90 to clamp the second end splicing section 622 to transfer the blank 60 away.

[0057] In some embodiments, the blank holding member 71 may include four moving members 712. The four moving members 712 may be disposed on the blank holding body 711 in pairs, and are respectively used to abut against four side surfaces of the first end splicing section 621.

[0058] In some embodiments, the blank holding member 71 may be a chuck, and the moving member 712 may be a claw in the chuck.

[0059] In some embodiments, as Figure 1 As shown, the blank transporter 90 may include a robotic arm 91 and a transport clamp 92 disposed at the end of the robotic arm 91. The transport clamp 92 is used to clamp the second end splicing section 622 of the blank 60. The robotic arm 91 has multiple degrees of freedom and is configured to drive the transport clamp 92 to a position facing the blank holder 71 to transfer the blank 60 from the blank holder 71 to the transport clamp 92; and to drive the transport clamp 92 to a position facing the cutting auxiliary clamp 81 to transfer the blank 60 to the cutting auxiliary clamp 81.

[0060] The embodiment of the present application uses a robotic arm 91 with multiple degrees of freedom and a transfer clamp 92 arranged at the end of the robotic arm 91, so that the robotic arm 91 can be rotated to different positions, thereby realizing the transfer of the blank 60 between the blank holder 71, the transfer clamp 92, and the cutting auxiliary clamp 81. It has high flexibility and can also stably and safely transfer the blank 60 to ensure that the blank 60 can be processed smoothly.

[0061] In some embodiments, see Figure 1 and Figure 9 The blank transport unit 90 may further include a mounting base 910 for mounting a robotic arm 91. The robotic arm 91 may include a first rotating member 911, a first connecting arm 912, a second rotating member 913, a second connecting arm 914, a third rotating member 915, a telescopic arm 916, a fourth rotating member 917, and a transport clamping rotating member 918. The first rotating member 911 is rotatably connected to the mounting base 910, and the first connecting arm 912 is connected to the first rotating member 911. The first rotating member 911 drives the first connecting arm 912 to rotate about a vertical axis relative to the mounting base.

[0062] The second connecting arm 914 is connected to the first connecting arm 912 through the second rotating member 913, and the second rotating member 913 drives the second connecting arm 914 to rotate around the first horizontal axis. The telescopic arm 916 is connected to the second connecting arm 914 through the third rotating member 915, and the third rotating member 915 drives the telescopic arm 916 to rotate around the second horizontal axis. The transfer clamping rotating member 918 is connected to the telescopic arm 916 through the fourth rotating member 917, and the fourth rotating member 917 drives the transfer clamping rotating member 918 to rotate around the third horizontal axis, and the third horizontal axis and the second horizontal axis are parallel to the first horizontal axis. The transfer clamping member 92 is connected to the transfer clamping rotating member 918, and the transfer clamping rotating member 918 is used to drive the transfer clamping member 92 to rotate around the fourth horizontal axis, and the fourth horizontal axis is perpendicular to the first horizontal axis. In such an embodiment, the blank transfer member 90 is capable of transferring the blank 60 from the blank holding member 71 to the cutting auxiliary clamp 81, and it is capable of precisely controlling the angle and spacing between the transfer clamp 92 and the cutting auxiliary clamp 81, so that the cutting member 82 can accurately process the blank 60 clamped by the cutting auxiliary clamp 81.

[0063] In some embodiments, the transport clamp 92 may include two oppositely disposed clamping jaws 921 for clamping the second end splicing section 622 of the blank 60.

[0064] In some embodiments, the blank transporter 90 is further configured to transfer the cut radioactive shock sample to the blank holder.

[0065] In some embodiments, as Figures 4 to 8 As shown, the cutting auxiliary clamping member 81 may include an auxiliary body 811, an auxiliary rotating portion 812 disposed on the auxiliary body 811, and two auxiliary clamping portions 813 disposed opposite to the auxiliary body 811. The two auxiliary clamping portions 813 may be configured to clamp the main body section 61 of the blank 60. The auxiliary rotating portion 812 may be used to drive the two auxiliary clamping portions 813 to rotate.

[0066] The embodiment of the present application utilizes the auxiliary rotating portion 812 to drive the two auxiliary clamping portions 813 to rotate, so that during the rotation of the two auxiliary clamping portions 813, the clamped blank 60 can follow the rotation, so as to facilitate cutting different surfaces of the blank 60 separately.

[0067] In some embodiments, as Figures 4 to 8As shown, the auxiliary clamping portion 813 may include an extension section 8131 and a first clamping section 8132. The first clamping section 8132 is connected to the extension section 8131. The first clamping section 8132 can be used to clamp the main section 61 of the blank 60. When the two first clamping sections 8132 clamp the main section 61 of the blank 60, the two extension sections 8131, the auxiliary body 811, and the first clamping sections 8132 together form a receiving groove 8130. The first end splicing section 621 is located between the two extension sections 8131, and the second end splicing section 622 is located outside the receiving groove 8130. A gap is provided between the first end splicing section 621 and the auxiliary body 811, the first clamping section 8132, and the extension section 8131, so that the cutting member 82 can enter the gap to cut the first end splicing section 621.

[0068] In the embodiment of the present application, the extension section 8131 and the first clamping section 8132 are arranged so that there is a gap between the first end splicing section 621 and the auxiliary body 811, the first clamping section 8132 and the extension section 8131. In this way, when the main section 61 of the blank 60 is clamped, the cutting piece 82 can not only cut the second end splicing section 622, but also cut the first end splicing section 621. There is no need to change the direction of the auxiliary clamping part 813 to clamp the blank 60, and the cutting efficiency is relatively high.

[0069] In some embodiments, two auxiliary clamping portions 813 may be disposed oppositely on the auxiliary body 811, and the two auxiliary clamping portions may have the same structure. In some embodiments, the auxiliary clamping portion 813 may include an extension section 8131 and a first clamping section 8132, and the first clamping section 8132 is connected to the extension section 8131.

[0070] In some embodiments, the first clamping sections 8132 of the two auxiliary clamping parts 813 can clamp the middle part of the main section 61 of the blank 60 to ensure that there are gaps between the first end splicing section 621 and the auxiliary body 811, the first clamping section 8132, and the extension section 8131.

[0071] In some embodiments, the distance between the two extension sections 8131 can be greater than the width of the first end splicing section 621; the distance between the auxiliary body 811 and the first clamping section 8132 can be greater than the length of the first end splicing section 621; and the width of the extension section 8131 of the auxiliary clamping portion 813 can be less than or equal to the width of the main section 61. This facilitates the cutting of the first end splicing section 621 by the cutting member 82.

[0072] In some embodiments, the width of the first clamping section 8132 of the auxiliary clamping portion 813 may be less than or equal to the width of the main section 61 so as not to affect the cutting of the first end splicing section 621 by the cutting piece 82 .

[0073] In some embodiments, the main body section 61 may include two first surfaces 611 and two second surfaces 612 disposed opposite to each other. One of the second surfaces 612 is used to form a V-shaped notch. The auxiliary clamping portion 813 may also include a second clamping segment 8133. The second clamping segment 8133 is connected to the first clamping segment 8132. The second clamping segments 8133 of the two auxiliary clamping portions 813 extend in opposite directions from their respective first clamping segments 8132 so that the two second clamping segments 8133 are staggered with each other. When the two first clamping segments 8132 and the two second clamping segments 8133 clamp the main body section 61 of the blank 60, the two opposite first surfaces 611 of the main body section 61 face the two first clamping segments 8132, and the two opposite second surfaces 612 face the two second clamping segments 8133.

[0074] The embodiment of the present application sets a second clamping section 8133, so that the two opposite first surfaces 611 and the two opposite second surfaces 612 of the main section 61 are clamped by the first clamping section 8132 and the second clamping section 8133 of the two auxiliary clamping parts 813 respectively. In this way, during the rotation process, it can be ensured that the blank 60 will not slide or fall, reducing the rotation error and thus ensuring the stability of the processing process.

[0075] In some embodiments, the second surface 612 used to form the V-notch is the same surface as the surface with the V-notch in the broken end of the radioactive shock sample before reconstruction, which helps to ensure that the performance of the reconstructed radioactive shock sample is the same as that of the radioactive shock sample before reconstruction.

[0076] In some embodiments, the first end splicing section 621 and the second end splicing section 622 respectively include two first splicing surfaces 6211 on the same side as the two first surfaces 611 and two second splicing surfaces 6221 on the same side as the two second surfaces 612. The first splicing surfaces 6211 and the second splicing surfaces 6221 protrude from the first surface 611 and the second surface 612 of the main body section 61, respectively.

[0077] In some embodiments, a through groove 81331 is formed on the surface of the second clamping segment 8133 facing the main body segment 61; when the two first clamping segments 8132 and the two second clamping segments 8133 clamp the main body segment 61 of the blank 60, a second gap is formed between the position of the second clamping segment 8133 corresponding to the through groove 81331 and a lateral surface of the main body segment 61, so that the cutting piece 82 can enter the second gap and cut a V-shaped notch on the main body segment 61.

[0078] The embodiment of the present application utilizes the through groove 81331 on the second clamping section 8133 to allow the cutting member 82 to enter the second gap and cut a V-shaped notch on the main section 61. Thus, during the processing, when the main section 61 of the blank 60 is clamped, the cutting member 82 can cut a V-shaped notch on the main section 61 of the blank 60, resulting in high cutting efficiency and simple operation.

[0079] In some embodiments, the two first clamping segments 8132 respectively form a clearance groove 81321; when the two first clamping segments 8132 and the two second clamping segments 8133 clamp the main segment 61 of the blank 60, the clearance grooves 81321 of the two first clamping segments 8132 overlap, so that the cutting piece 82 can enter the clearance grooves 81321 of the two first clamping segments 8132 after entering the second gap, thereby cutting a V-shaped notch on the main segment 61.

[0080] In the embodiment of the present application, a clearance groove 81321 is formed on the first clamping section 8132 to facilitate cutting a V-shaped notch on the main body section 61 .

[0081] It is easy to understand that for the two auxiliary clamping parts 813, the structures of the extension sections 8131 and the first clamping sections 8132 are exactly the same, and the second clamping sections 8133 are arranged opposite each other. The two clearance grooves 81321 of the two auxiliary clamping parts 813 are located at different positions on the two first clamping sections 8132.

[0082] For ease of distinction, one of the auxiliary clamping portions 813 is referred to as the first auxiliary clamping portion 813, and the other auxiliary clamping portion 813 is referred to as the second auxiliary clamping portion 813. In some embodiments, a side of the first clamping section 8132 of the first auxiliary clamping portion 813 away from the second clamping section 8133 may form a clearance groove 81321. A side of the first clamping section 8132 of the second auxiliary clamping portion 8133 closer to the second clamping section 8133 may also form a clearance groove 81321.

[0083] When the first clamping section 8132 of the first auxiliary clamping part 813, the first clamping section 8132 of the second auxiliary clamping part 813, the second clamping section 8133 of the first auxiliary clamping part 813 and the second clamping section 8133 of the second auxiliary clamping part 813 clamp the main section 61 of the blank 60, the clearance grooves 81321 of the two first clamping sections 8132 can overlap.

[0084] In some embodiments, as Figure 10As shown, when the two auxiliary clamping parts 813 clamp the blank 60, the two second splicing surfaces 6221 of the second end splicing section 622 of the blank 60 can be cut in turn, and then the two auxiliary clamping parts 813 are rotated 90 degrees to cut the first splicing surface 6211 of the second end splicing section 622 of the blank 60 in turn, and then the first end splicing section 621 of the blank 60 is cut in a similar cutting method, and finally a V-shaped notch is cut on the second surface 612 of the main section 61 to finally obtain a radioactive impact sample.

[0085] The embodiments of the present application further provide a method for processing a radioactive shock sample. The processing method can utilize the processing system of any embodiment of the present application to process a radioactive shock sample blank 60 formed by welding to form the radioactive shock sample.

[0086] In some embodiments, the processing method may include: when using the auxiliary clamping part 813 to clamp the main section 61 of the blank 60, the auxiliary rotating part 812 can be rotated so that the weld 64 between the main section 61 and the end splicing section is facing the cutting piece 82; and then the electrode wire of the wire-cut electric spark cutting is used to cut the parts of the two end splicing sections protruding from the main section 61.

[0087] Specifically, the blank 60 is transported into the hot chamber and placed by the hot chamber manipulator on the blank holder 71 on the operating table. The blank 60 is then clamped by the blank holder 71. The blank 60 is then grasped from the blank holder 71 by the transport clamp 92 of the blank transport unit 90. The blank 60 is then placed by the transport clamp 92 of the blank transport unit 90 on the cutting auxiliary clamp 81 of the wire-cut electric discharge machine 80, which clamps the blank 60.

[0088] Afterwards, the radial and axial coaxial errors of the wire-cut EDM machine 80 are automatically aligned with coordinate offsets. Data obtained after two close-proximity discharges with the molybdenum wire determine the straightness of the auxiliary cutting fixture 81 at a 90-degree angle, while also performing coordinate offset correction. After rotational alignment, the machining coordinates and actual coordinates are essentially aligned, eliminating machining errors caused by fixture errors.

[0089] According to the previously calibrated coordinates, the molybdenum wire directly cuts the two second splicing surfaces 6221 of the second end splicing section 622 in sequence with the cutting auxiliary clamp 81 at the 0-degree position against the main section 61, and then the two auxiliary clamping parts 813 are rotated 90 degrees to cut the first splicing surface 6211 of the second end splicing section 622 of the blank 60 in sequence, and then the first end splicing section 621 of the blank 60 is cut in a similar cutting method, and finally a V-shaped notch is cut on the second surface 612 of the main section 61 to finally obtain a 10mm×10mm×55mm standard Charpy impact specimen.

[0090] The embodiment of the present application further provides a method for preparing a radioactive impact sample, which may include at least steps S11 and S12.

[0091] Step S11: welding the welding base material to form a blank 60 of the radioactive impact sample. The welding base material may include a main body section 61 and two end splicing sections respectively used for welding to both ends of the main body section. The main body section 61 is radioactive.

[0092] Step S12: Process the blank 60 using the processing method of the embodiment of the present application to form a radioactive impact sample.

[0093] In some embodiments, before step S11, the preparation method may further include step S10.

[0094] Step S10: cutting a side section of the impact sample broken head away from the notch to facilitate welding; cutting a section of the impact sample broken head of a preset length as the main body section 61.

[0095] In the embodiment of the present application, the main body segment 61 obtained through step S10 will not be deformed in the previous impact test, so the reconstruction measurement can be more accurate.

[0096] In some embodiments, when cutting the side section of the impact sample away from the notch, the cutting width can be relatively small, for example, 0.5 mm. The preset length can be 20 mm.

[0097] In some embodiments, the parent material may be welded using an electron beam welding device to form a blank 60 of the radioactive impact sample.

[0098] The embodiment of the present application further provides an electron beam welding device for welding a welding base material to form a blank 60 of a radioactive impact sample.

[0099] In some embodiments, as Figure 12 and Figure 13 As shown, the electron beam welding apparatus may include a main body, an electron gun 20, a movable platform 31, and a temperature measurement assembly 40. The main body is configured to form a vacuum chamber 10. The electron gun 20 can be used to provide an electron beam to the vacuum chamber 10. The movable platform 31 can be used to mount a welding fixture 50 and is configured to drive the welding fixture 50 to translate within the vacuum chamber 10 to weld the base metal using the electron beam. The temperature measurement assembly 40 can be used to measure the temperature of the main body section 61 assembled in the welding fixture 50 during welding.

[0100] Regarding the use of welding to reassemble a small number of radioactive samples into a Charpy V-shaped impact specimen capable of undergoing impact testing, the inventors of this application discovered that in order to avoid affecting the performance of the radioactive impact specimen, thereby leading to inaccurate impact test results on the prepared radioactive impact specimen, it is necessary to prevent the temperature in the middle of the main body section 61 from being too high during welding. Therefore, the embodiments of this application provide a temperature measurement component in the electron beam welding apparatus to measure the temperature of the main body section 61 assembled in the welding fixture 50 during welding. This helps ensure the quality of the welded radioactive impact specimen blank 60, avoids changes in the performance of the main body section 61, and ensures that the reconstructed radioactive impact specimen accurately reflects the performance of the original radioactive impact specimen.

[0101] In the embodiment of the present application, by measuring the temperature of the main section 61, on the one hand, it is helpful to adjust the welding parameters so as to try to ensure that the temperature of the main section 61 does not exceed the preset temperature during welding; on the other hand, if the temperature exceeds the preset temperature during the welding process, it can be directly judged that the blank 60 of the formed radioactive impact sample is an unqualified blank 60, and no subsequent operations are performed, which saves time costs and avoids subsequent invalid operations.

[0102] In some embodiments, as Figure 11 As shown, the main body may include a chamber body 11 and a chamber cover 12. The chamber body 11 has an opening formed on one side. The chamber cover 12 can be used to seal the opening of the chamber body 11, thereby forming a vacuum chamber 10 together with the chamber body 11. The chamber body 11 may have a window 13 for observing the welding process. The electron gun 20 may be disposed above the chamber body 11. The movable platform 31 and the temperature measurement assembly 40 may be disposed on the chamber cover 12.

[0103] In some embodiments, the chamber cover 12 can slide relative to the chamber body 11 to seal or open the opening of the chamber body 11. A sealing portion 121 can be provided on the side of the chamber cover 12 facing the chamber body 11 to ensure the sealing of the vacuum chamber 10.

[0104] When the chamber cover 12 seals the opening of the chamber body 11, the movable platform 31 and the temperature measurement assembly 40 enter the chamber body 11 to weld the main body section 61 and the end splicing section using the electron beam provided by the electron gun 20. When the chamber cover 12 opens the opening of the chamber body 11, the movable platform 31 and the temperature measurement assembly 40 are removed from the chamber body 11, allowing the welding fixture 50 to be installed on or removed from the movable platform 31.

[0105] In some embodiments, the electron beam welding device may further include a support platform 30. The support platform 30 may be connected to the open side of the chamber cover 12 facing the chamber body 11. During the process of sealing the chamber cover 12 to the chamber body 11, the support platform 30 on the chamber cover 12 can move along with the chamber cover 12, thereby entering the vacuum chamber 10. The movable platform 31 may be disposed on the support platform 30 and slidably connected to the support platform 30. During welding, the movable platform 31 can move relative to the support platform 30 so that the electron beam can be aligned with the gap between the main section 61 and each end splicing section, and can move along the extension direction of the gap, thereby completing welding using the electron beam. After welding is completed, a weld can be formed at the position corresponding to the gap. When welding of the current weld is completed and another weld needs to be welded, the movable platform 31 can move relative to the support platform 30 along a first direction perpendicular to the extension direction of the weld.

[0106] In some embodiments, the mobile platform 31 may include a mobile body 311 and a sliding portion 312. The support platform 30 may include a support body 301 and a sliding mating portion 302. The sliding mating portion 302 and the sliding portion 312 may extend in a direction parallel to the direction of extension of the weld in the embodiment of the present application. By connecting the sliding mating portion 302 and the sliding portion 312, the mobile body 311 may be slidably disposed on the support body 301. For example, the sliding mating portion 302 may be a slide rail, and the sliding portion 312 may be a slide groove.

[0107] In some embodiments, the electron gun 20 is configured to be movable relative to the chamber body 11 so that the electron beam can be aligned with the gap between the main body segment 61 and each end joint segment. It will be readily understood that the direction of movement of the electron gun 20 relative to the chamber body 11 can be perpendicular to the direction of movement of the movable platform 31 relative to the support platform 30.

[0108] In some embodiments, as Figure 12 As shown, the electron beam welding device may include a first mounting plate 21, a second mounting plate 22 and a driving portion 23, the electron gun 20 is connected to the first mounting plate 21, the second mounting plate 22 is connected to the chamber body 11, the first mounting plate 21 and the second mounting plate 22 can slide relative to each other, and the driving portion 23 is used to drive the first mounting plate 21 to slide relative to the second mounting plate 22.

[0109] The first mounting plate 21 is formed with a sliding mounting portion 211. The second mounting plate 22 may be formed with a sliding mounting fitting portion 221 for fitting with the sliding mounting portion 211, so that the first mounting plate 21 can slide relative to the second mounting plate 22 through the sliding fitting between the sliding mounting portion 211 and the sliding mounting fitting portion 221.

[0110] In some embodiments, the electron beam welding apparatus may further include a frame, which may be used to mount the chamber body 11 and the chamber cover 12. The chamber cover 12 may be slidably disposed on the frame.

[0111] In some embodiments, see Figure 15 The temperature measurement assembly 40 may include multiple temperature measurement elements 43 and multiple protective members 41. The multiple temperature measurement elements 43 are configured to abut against the main body section 61 to measure the temperature of the main body section 61. Each temperature measurement element 43 extends within a protective member 41 to a point where it protrudes from the protective member 41. Each protective member 41 may be configured to prevent the sputtering beam generated during electron beam welding from contacting a corresponding temperature measurement element 43.

[0112] The inventors of this application discovered that when electron beam welding is performed, the temperature measured by the temperature measuring element 43 is too high. The inventors further discovered that when electron beam welding is performed, the electron beam forms a sputtering beam. Because the temperature measuring element 43 is relatively close to the weld, for example, the gap between the two is only 2-5 mm, the sputtering beam will contact the temperature measuring element 43. The sputtering beam has a high temperature, which affects the measurement results of the temperature measuring element 43 and causes the temperature measured by the temperature measuring element 43 to be too high. The embodiments of this application, by providing a protective member 41 outside each temperature measuring element 43, can block the sputtering beam and prevent the sputtering beam from contacting the temperature measuring element 43, thereby facilitating the accurate measurement of the welding temperature.

[0113] In some embodiments, during welding, the welding temperature can be measured at a preset position on the main body segment 61. There can be two preset positions. In some embodiments, the preset position can be a position at a preset distance from the center of the main body segment 61 to the end thereof. In some embodiments, the preset position can be a position 7 mm from the center of the main body segment 61 to the end thereof.

[0114] In some embodiments, the temperature measuring element 43 is used to measure the welding temperature at a preset position of the main body segment 61 during the welding process in real time.

[0115] In some embodiments, the temperature measuring element 43 may be a thermocouple, such as an ultra-high-speed thermocouple. When the ultra-high-speed thermocouple is very sensitive to temperature changes, providing the protective member 41 can better prevent the electron beam and the sputtering beam from affecting the welding temperature measurement results during the welding process.

[0116] In some embodiments, the protective member 41 may be a ceramic tube. Ceramics have good thermal insulation properties. Using a ceramic tube as the protective member 41 not only blocks the sputtering beam but also provides thermal insulation, preventing the heat of the sputtering beam from being transferred to the temperature measuring element 43.

[0117] In some embodiments, the length of the temperature measuring element 43 protruding from the protective member 41 can be 0.01-0.1 mm, so that it can contact the main section 61 for temperature measurement. In the embodiment of the present application, the portion of the temperature measuring element 43 protruding from the protective member 41 is within the range of 0.01-0.1 mm. This can minimize the protrusion of the temperature measuring element 43 from the protective member 41 while ensuring that the temperature measuring element 43 can abut the main section 61, thereby preventing the sputtering beam from contacting the temperature measuring element 43.

[0118] In some embodiments, the temperature measurement assembly 40 may include a holder 42 . The temperature measurement element 43 may be disposed on the holder 42 . The protection member 41 extends from the holder 42 toward the moving platform 31 .

[0119] In the embodiment of the present application, a retaining member 42 is provided in the temperature measuring assembly 40 , and the temperature measuring element 43 and the protective member 41 are provided on the retaining member 42 , so that the temperature measuring element 43 and the protective member 41 can remain stable and not easily shaken.

[0120] In some embodiments, the electron beam welding device may further include a fixed platform 32. The fixed platform 32 may be disposed on the movable platform 31, and the welding fixture 50 may be connected to the fixed platform 32. In some embodiments, the welding fixture 50 may be connected to the fixed platform 32 by means of a hole-pin fit.

[0121] In some embodiments, as Figure 16 As shown, the welding fixture 50 may include multiple clamping members 51, a frame 53, and a base plate 52. The frame 53 is connected to the base plate 52, and together they form a base material receiving groove for arranging the base material to be welded. The clamping members 51 are used to press the base material against the base plate 52 to prevent the base material from shaking during welding and affecting the welding quality. The frame 53 may be a one-piece structure.

[0122] In some embodiments, the extension direction of the compression member 51 can be the same as the extension direction of the weld. The compression member 51 can include a compression body 512 and a compression connection portion 511. A compression fitting portion can be formed on the frame 53. The compression body 512 and the frame 53 can be connected by the compression connection portion 511 and the compression fitting portion.

[0123] In some embodiments, the compression connection portion 511 can be a threaded fastener, and the compression fitting portion can be a threaded hole. The compression body 512 can be threadedly connected to the frame 53. When the compression member 51 is connected to the frame 53 using the threaded fastener, the welding base material and the base plate 52 can be compressed.

[0124] In some embodiments, as Figure 10 、 Figure 14 and Figure 16 As shown, the end splicing section can include a main splicing section 62 and two auxiliary splicing sections 63. The two auxiliary splicing sections 63 are located on either side of the main splicing section 62. When welding the end splicing section to the main section 61, the auxiliary splicing sections 63 provide arc starting and arc ending positions for the weld 64, ensuring weld quality. After welding is completed, the four auxiliary splicing sections 63, the two main splicing sections 62, and the main section 61 form a single structure, which is the blank 60 of the radioactive impact specimen.

[0125] In some embodiments, the first end splicing segment 621 and the second end splicing segment 622 in the embodiment of the present application may respectively include a splicing body segment 62 and two splicing auxiliary segments 63 located on both sides of the splicing body segment 62 .

[0126] In some embodiments, as Figure 14 and Figure 15 As shown, the retaining member 42 may include two mounting portions 421 disposed opposite each other and a positioning portion 422 formed between the two mounting portions 421. The mounting portions 421 may be used to mount the protective member 41. The positioning portion 422 may be configured to cooperate with a pressing member 51 that presses the middle portion of the main body section 61 against the bottom plate 52, so that the two mounting portions 421 can symmetrically measure the temperature at locations on both sides of the main body section 61 at a predetermined distance from the weld seam 64.

[0127] The embodiment of the present application can measure the temperature of the positions at a preset distance from the weld 64 on both sides of the main section 61 by installing multiple protective parts 41 on two oppositely arranged mounting parts 421, so as to further ensure the accuracy of the weld temperature measurement results and thus ensure the welding quality.

[0128] In some embodiments, a plurality of protection members 41 may be provided for each mounting portion 421 .

[0129] In some embodiments, the positioning portion 422 is a positioning groove. The pressing member 51 can enter the positioning groove. In the embodiments of the present application, by configuring the positioning portion 422 as a positioning groove into which the pressing member 51 can enter, the two mounting portions 421 are conveniently aligned with the welding fixture 50, thereby ensuring that the temperature measuring element 43 can approach the weld and measure the weld temperature.

[0130] In some embodiments, the temperature measurement assembly 40 may further include a rotating member 44. The rotating member 44 may be configured to drive the holder 42 to rotate, thereby positioning the holder 42 directly above the welding fixture 50 so that the temperature measuring element 43 can contact the main body section 61 for temperature measurement, and to rotate the holder 42 to a position that allows the welding fixture 50 to be assembled and disassembled from the mobile platform 31.

[0131] In the embodiment of the present application, by providing a rotating part 44 in the temperature measuring assembly 40, the retaining part 42 can be rotatably set at a position directly above the welding fixture 50, so that when the temperature of the main section 61 needs to be measured, the temperature measuring element 43 can be used to accurately measure the temperature; when the temperature of the main section 61 does not need to be measured, the welding fixture 50 can be conveniently disassembled.

[0132] In some embodiments, as Figure 13 As shown, the rotating member 44 may include a rotating body 441 and two rotating brackets 442. The rotating body 441 is rotatably disposed on the two rotating brackets 442. The holding member 42 is disposed on the rotating body 441 so that the rotating body 441 drives the holding member 42 to rotate.

[0133] In some embodiments, the holder 42 may include a holding body 420 , and two mounting portions 421 are connected to the holding body 420 . The holding body 420 is connected to a rotating body 441 .

[0134] In some embodiments, the rotating member 44 may further include a driving member and a rotating shaft 443 , wherein the rotating shaft 443 is used to connect the driving member and the rotating body 441 , so that the driving member drives the rotating body 441 to rotate.

[0135] In some embodiments, the two rotating brackets 442 are mounted on the moving body 311 of the moving platform 31 to move together with the moving body 311 .

[0136] In some embodiments, the rotating member 44 may further include a sliding bearing 444 and a sliding connection portion 445. The sliding bearing 444 may be used to connect to the chamber cover 12. The sliding connection portion 445 may be used to connect to the rotating shaft 443. The sliding connection portion 445 is formed with a slide groove 446. The sliding bearing 444 is slidingly disposed in the slide groove 446 of the sliding connection portion 445. The extension direction of the slide groove 446 is the same as the movement direction of the movable body 311 relative to the supporting body 301, so that when the movable body 311 drives the two rotating brackets 442 and the rotating body 441 to move, the sliding bearing 444 is kept in cooperation with the rotating shaft 443 by the movement of the sliding bearing 444 along the slide groove 446.

[0137] Embodiments of the present application also provide a welding method for welding a base material to form a blank for a radioactive impact specimen. The base material may include a main body section 61 and two end sections for welding to the ends of the main body section 61. The main body section 61 is radioactive. The welding method may include at least the following steps S21 and S23.

[0138] Step S21 : placing the main body section 61 and the two end splicing sections in a welding fixture 50 for positioning.

[0139] Step S22: Use the electron beam welding device of any embodiment of the present application to weld the main body section 61 and the two end splicing sections.

[0140] In step S23 , the temperature of the main body section 61 is measured by the temperature measuring element 43 , and whether the welded blank 60 is qualified is determined based on the measured temperature.

[0141] The welding method of the embodiment of the present application can determine whether the welded blank 60 is qualified based on the measured temperature, and process the qualified blank 60 into a radioactive shock sample, which is conducive to ensuring that the reconstructed radioactive shock sample can accurately reflect the performance of the original radioactive shock sample; at the same time, for the unqualified blank 60, there is no need to perform subsequent operations, saving time costs and avoiding subsequent invalid operations.

[0142] In some embodiments, during welding, the welding temperature can be measured at a preset position on the main body segment 61. There can be two preset positions. In some embodiments, the preset position can be a position at a preset distance from the center of the main body segment 61 to the end thereof. In some embodiments, the preset position can be a position 7 mm from the center of the main body segment 61 to the end thereof.

[0143] In some embodiments, the temperature measuring element 43 is used to measure the welding temperature at a preset position of the main body segment 61 during the welding process in real time.

[0144] In some embodiments, when the temperature measured by the temperature measuring element 43 reaches a preset temperature threshold, the blank 60 is unqualified and cannot be used; when the temperature measured by the temperature measuring element 43 is always lower than the preset temperature threshold, the blank 60 is qualified.

[0145] In the embodiments of the present application, the preset temperature threshold can be determined through experimentation. It will be readily understood that the preset temperature threshold is related to the location at which the temperature measuring element 43 is measuring. The closer the temperature measuring element 43 is to the weld, the higher the corresponding preset temperature threshold. In some embodiments, the temperature at a point 7 mm from the center of the main body segment 61 to the end thereof cannot exceed 250°C.

[0146] In some embodiments, the welding fixture can be Figure 16 The welding fixture 50 is shown. In some embodiments, if the total length of the main section 61 and the two end splicing sections is 55 mm, the length of the main section 61 can be 20 mm, and the initial length of the end splicing sections can be greater than 17.5 mm, so that the length of the end splicing sections after processing is 17.5 mm.

[0147] In some embodiments, the width of weld 64 may be 2 mm.

[0148] In order to prevent the temperature of the main section 61 from exceeding the preset temperature threshold, during welding, it is necessary to make the melting zone (the melting zone is the area formed after the welding base material near the weld 64 melts during the welding process) narrow enough and the width of the weld 64 small enough to reduce the diffusion of heat to the middle of the main section 61, so that the temperature at the preset position of the main section 61 will not exceed the preset temperature threshold.

[0149] In some embodiments, the welding parameters of the electron beam welder can be set to: a welding speed of 9 mm, a welding electron beam current of 45 mA, and a focus position of 3 mm. The inventors of this application conducted experiments combining different welding speeds, different welding electron beam currents, and different focus positions and found that using the above welding parameters is beneficial for both ensuring full penetration of the main body section 61 and the end splicing section, and ensuring that the temperature of the main body section 61 does not exceed a preset temperature threshold.

[0150] In some embodiments, the main body segment 61 is formed of radioactive ferrite; before placing the main body segment 61 and the two end splicing segments in the welding fixture 50 for assembly and positioning (step S1), the welding method may further include step S0: demagnetizing the main body segment 61 and the two end splicing segments.

[0151] The inventors of this application discovered that when electron beam welding is performed directly on the main body section 61 formed of radioactive ferrite, the electron beam will deviate due to the ferrite's magnetic field, which in turn affects the electron beam's focus position and the weld position, resulting in an uneven weld width. If the width of weld seam 64 is uneven, the weld edge at some locations may be too close to the center of main body section 61, causing the temperature in the center of main body section 61 to rise, ultimately resulting in failure of the prepared radioactive impact test blank.

[0152] The embodiment of the present application demagnetizes the main section 61 and the two end splicing sections before welding, which helps to ensure that the focusing position of the electron beam and the welding position are more accurate, thereby helping to avoid the temperature of the middle part of the main section 61 from rising during the welding process.

[0153] In some embodiments, before demagnetizing the main body section 61 and the two end splicing sections, the main body section 61 and the two end splicing sections can be surface cleaned and pretreated to remove impurities such as oil, oxides, etc. on the end surfaces to be welded of the main body section 61 and the two end splicing sections, thereby improving the welding quality.

[0154] Specifically, the end surfaces of the main body section 61 and the two end splicing sections to be welded can be polished in sequence using 400-grit, 600-grit, and 800-grit sandpaper to remove oxides. After polishing, the end surfaces of the main body section 61 and the two end splicing sections to be welded can be ultrasonically cleaned with acetone to remove oil stains, impurities such as polishing fluid, and so on.

[0155] In some embodiments, the main body section 61 and the two end splicing sections can be demagnetized using a demagnetizer. After the demagnetization is completed, the end surfaces of the main body section 61 and the two end splicing sections to be welded can be wiped again with acetone to remove impurities such as oil.

[0156] The following describes in detail the welding process using the method of the embodiment of the present application in conjunction with the drawings and specific embodiments.

[0157] According to the performance and material of the main section 61 of the welding base material, the splicing main section 62 and the splicing auxiliary section 63 with material properties close to those of the main section 61 are selected to facilitate the formation of a radioactive shock sample with the same performance as the radioactive shock sample before reconstruction.

[0158] Polish the welded end surfaces of the main body section 61 and the spliced body section 62 using 400-, 600-, and 800-grit sandpaper in order to remove oxides. After polishing, ultrasonically clean the welded end surfaces of the main body section 61 and the spliced body section 62 using acetone to remove oil, impurities such as polishing fluid, and other impurities.

[0159] Use a demagnetizer to demagnetize the main body section 61, the spliced main body section 62 and the spliced auxiliary section 63. After the demagnetization is completed, the end surfaces to be welded of the main body section 61 and the spliced main body section 62 can be wiped again with acetone to remove impurities such as oil.

[0160] The welding fixture 50 of the embodiment of the present application and the main section 61, the spliced main section 62 and the spliced auxiliary section 63 that have been polished, ultrasonically cleaned, demagnetized, etc. are assembled and placed on the mobile platform 31; then the temperature measuring assembly 40 is rotated so that the temperature measuring elements 43 on both sides are respectively abutted against the two preset positions of the main section 61 to perform real-time measurement of the welding temperature of the preset positions of the main section 61; and the chamber cover 12 of the electron beam welding device is closed.

[0161] The vacuum system is activated to evacuate the vacuum chamber 10 formed by the chamber body 11 and the chamber lid 12. The movable platform 31 is controlled to translate so that the junction of the main body segment 61 and the spliced body segment 62 is aligned with the electron beam. Welding parameters are input and the electron beam welding device is activated to weld the junction of the main body segment 61 and the spliced body segment 62 using the electron beam. The welding parameters may be: a welding speed of 9 mm, a welding electron beam current of 45 mA, and a focus position of 3 mm.

[0162] After the current weld seam is welded and the main body segment 61 and the other end segment are welded, the movable platform 31 is used to move the joint between the main body segment 61 and the other end segment to a position aligned with the electron beam, so that the electron beam can weld the welded position. After welding is completed, the four auxiliary segments 63, the two main body segments 62, and the main body segment 61 form a single structure, namely, the blank 60 of the radioactive impact specimen.

[0163] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.
