Description

Technical Field

[0001] This invention relates to the field of parts processing technology, and in particular to a low-stress processing and deformation feedback control device for metal spherical shells. Background Technology

[0002] Residual stress is an inevitable product of mechanical manufacturing and a major cause of deformation during the machining and subsequent service of thin-walled metal components in critical equipment. Aluminum alloy spherical shells have a large amount of material removed during machining, are prone to deformation during processing, have poor resistance to elastic deformation, and exhibit large deformation after machining, making it difficult to meet the requirements for dimensional accuracy. Their quality has a significant impact on the reliability and service safety of critical equipment. Controlling the machining accuracy and service conformity of components means controlling the distribution of residual stress. Removing residual stress during various machining processes such as turning, milling, boring, and grinding, and ensuring the dimensional accuracy of the spherical shell, is of great significance to the manufacturing of critical equipment.

[0003] Currently, there is no ideal method for stress relief in metal spherical shell workpieces. Existing stress relief methods include annealing, tempering, and vibration impact, but these methods are not only energy-intensive but also damage the workpiece, making them unsuitable for high-precision metal spherical shell components. Since stress in metal spherical shells is generated throughout the entire machining process, it is inconvenient to frequently use energy-intensive stress relief methods such as annealing, thus making it difficult to control machining accuracy. Therefore, there is an urgent need for a non-destructive stress relief device for metal spherical shells to remove residual stress during low-stress machining, control deformation, and improve the shape accuracy of the spherical shell.

[0004] Therefore, there is an urgent need for a low-stress machining and deformation feedback control device for metal spherical shells, which can more easily remove residual stress from metal spherical shells and improve the machining accuracy of the spherical shells. Summary of the Invention

[0005] In view of the above-mentioned problems of the prior art, this application provides a low-stress processing and deformation feedback control device for metal spherical shells, which can more conveniently remove residual stress from metal spherical shells and improve the processing accuracy of spherical shells.

[0006] This application provides a low-stress processing and deformation feedback control device for a metal spherical shell, comprising: a worktable; a detection device disposed on the worktable for detecting residual stress within the metal spherical shell and obtaining detection results; and a spherical stress control device disposed on the worktable, having multiple high-energy ultrasonic exciters, the emitting ends of the high-energy ultrasonic exciters being arranged along the outer circumferential surface of the metal spherical shell and facing the center of the metal spherical shell; wherein, the spherical stress control device controls the high-energy ultrasonic exciters to emit ultrasonic waves according to the detection results.

[0007] Using the above structure, after placing the metal spherical shell on the worktable, the residual stress inside the shell can be detected by a detection device. Based on the detection results, the spherical stress control device can reduce the residual stress inside the shell by using ultrasonic waves emitted from high-energy ultrasonic exciters arranged along the outer circumference of the shell. This reduces deformation after machining and improves the machining accuracy of the metal spherical shell. Furthermore, using ultrasonic waves emitted from the high-energy ultrasonic exciter to reduce residual stress inside the shell is simple to operate and consumes little energy.

[0008] In some embodiments, the workbench includes: a housing, in which the detection device and the spherical stress control device are disposed; and a fan disposed on the housing and blowing air toward the housing.

[0009] With the above structure, a fan can blow air into the housing, thereby cooling the device inside the housing.

[0010] In some embodiments, the housing is rectangular in shape, and two fans are provided on each of the four sides of the housing.

[0011] By adopting the above structure and installing two fans on each of the four sides, the cooling performance can be improved, ensuring the stability of the equipment inside the housing.

[0012] In some embodiments, the workbench further includes a mounting port disposed on the housing, through which the metal spherical shell enters the housing.

[0013] With the above structure, the installation of the metal spherical shell can be conveniently achieved by setting an installation port on the shell.

[0014] In some embodiments, the spherical stress control device includes: a mounting frame, the mounting frame being hemispherically disposed within the housing for accommodating the metal spherical shell, the opening of the mounting frame being disposed facing the mounting port, and the high-energy ultrasonic exciter being disposed on the mounting frame, the emitting end of the high-energy ultrasonic exciter being located on the inner surface of the mounting frame and in contact with the outer surface of the metal spherical shell.

[0015] With the above structure, the high-energy ultrasonic exciter can be easily installed by setting a hemispherical mounting bracket, so that the emitting end of the high-energy ultrasonic exciter can be attached to the outer surface of the metal spherical shell.

[0016] In some embodiments, the high-energy ultrasonic exciters are evenly distributed on the mounting frame.

[0017] By adopting the above structure, the effect of high-energy ultrasonic exciter on homogenizing and eliminating residual stress inside the metal spherical shell can be improved.

[0018] In some embodiments, the spherical stress control device further includes: a control bolt, which is disposed on the mounting bracket, and the high-energy ultrasonic exciter is slidably connected to the control bolt and slides along the direction toward the center of the metal spherical shell; and a spring, which is sleeved on the control bolt, with one end of the spring abutting against the head of the control bolt and the other end pushing the high-energy ultrasonic exciter to move toward the center of the mounting bracket.

[0019] With the above structure, the high-energy ultrasonic exciter can be pushed by a spring to move towards the spherical shape of the mounting frame, that is, to move the high-energy ultrasonic exciter towards the metal spherical shell, so that the emitting end of the high-energy ultrasonic exciter is closely attached to the outer peripheral surface of the metal spherical shell, thereby improving the propagation effect of ultrasonic waves and improving the reduction effect of residual stress.

[0020] In some embodiments, the spherical stress adjustment device further includes: a height adjustment support, which is vertically disposed at the bottom center of the mounting frame, the lower end of the height adjustment support is threadedly connected to the mounting frame, the upper end is used to support the metal spherical shell, and the height of the upper end of the height adjustment support is adjusted by rotating the height adjustment support.

[0021] The above structure allows for improved stability of the metal spherical shell within the mounting frame by adjusting the height of the support member. The height of the metal spherical shell can be adjusted by rotating the support member, ensuring its center aligns with the center of the mounting frame. This improves the fit between the high-energy ultrasonic exciter's transmitter and the metal spherical shell, thereby enhancing the reduction of residual stress.

[0022] In some embodiments, the worktable further includes a clamping member disposed on the housing for pressing and fixing the metal spherical shell within the mounting bracket.

[0023] With the above structure, the metal spherical shell inside the mounting bracket can be pressed and fixed by the clamping component, thereby improving the stability of the metal spherical shell and enhancing the reduction of residual stress.

[0024] In some embodiments, the workbench further includes: legs, wherein multiple legs are provided for supporting the housing; and height-adjusting casters, wherein multiple height-adjusting casters are provided and respectively disposed at the bottom of the legs.

[0025] With the above structure, the flexibility and stability of the worktable can be improved by adjusting the height of the casters.

[0026] These and other aspects of the invention will become more apparent from the following description of several embodiments. Attached Figure Description

Furthermore, in one or more embodiments, the particular features, structures, or characteristics can be combined in any suitable manner, as will be apparent to those skilled in the art from this disclosure.

[0042] The following, with reference to the accompanying drawings, provides a detailed description of possible embodiments of the metal spherical shell low-stress processing and deformation feedback control device 10 of this application.

[0043] Figure 1 This is a three-dimensional structural diagram of the metal spherical shell low-stress processing and deformation feedback control device 10 in an embodiment of this application. Figure 1As shown, the low-stress processing and deformation feedback control device 10 for metal spherical shells in this embodiment includes: a worktable 100; a detection device 200, which is disposed on the worktable 100 and used to detect the residual stress in the metal spherical shell 20 and obtain the detection result; and a spherical stress control device 300, which is disposed on the worktable 100 and has multiple high-energy ultrasonic exciters 310. The emitting ends of the high-energy ultrasonic exciters 310 are arranged along the outer peripheral surface of the metal spherical shell 20, and the emitting ends of the high-energy ultrasonic exciters 310 are arranged facing the center of the metal spherical shell 20. The spherical stress control device 300 controls the high-energy ultrasonic exciters 310 to emit ultrasonic waves according to the detection result.

[0044] As described above, after the metal spherical shell 20 is placed on the worktable 100, the residual stress inside the metal spherical shell 20 can be detected by the detection device 200. Based on the detection results, the spherical stress control device 300 can reduce the residual stress inside the metal spherical shell 20 by using ultrasonic waves emitted from a high-energy ultrasonic exciter 310 arranged along the outer circumference of the metal spherical shell 20. This reduces the deformation of the spherical shell after machining and improves the machining accuracy of the metal spherical shell 20. Furthermore, the method of reducing residual stress inside the metal spherical shell 20 using ultrasonic waves emitted from the high-energy ultrasonic exciter 310 is simple to operate and has low energy consumption.

[0045] Figure 2 for Figure 1 A three-dimensional structural diagram of the middle workbench 100. (See diagram below.) Figure 2 As shown, in some embodiments, the workbench 100 includes: a housing 110, a detection device 200 and a spherical stress adjustment device 300 disposed inside the housing 110; and a fan 150 disposed on the housing 110 and blowing air into the housing 110. Thus, the device inside the housing 110 can be cooled by the fan 150 blowing air into the housing 110.

[0046] like Figure 2 As shown, in some embodiments, the housing 110 is rectangular, and two fans 150 are provided on each of the four sides of the housing 110. Thus, by providing two fans 150 on each of the four sides, the cooling performance can be improved, ensuring the stability of the equipment operation inside the housing 110.

Figure 1 , Figure 3As shown, in some embodiments, the workbench 100 further includes a mounting port 160, which is disposed on the housing 110, through which the metal spherical shell 20 enters the housing 110. Thus, by providing the mounting port 160 on the housing 110, the installation of the metal spherical shell 20 can be facilitated.

[0048] Figure 4 for Figure 3 Schematic diagram of the bottom structure of the 300-type spherical stress control device; Figure 5 for Figure 3 A three-dimensional structural schematic diagram of the spherical stress control device 300. (See diagram below.) Figure 4 , Figure 5 As shown, in some embodiments, the spherical stress control device 300 includes: a mounting frame 320, which is hemispherically disposed within the housing 110 to accommodate the metal spherical shell 20; the opening of the mounting frame 320 faces the mounting port 160; and a high-energy ultrasonic exciter 310 is disposed on the mounting frame 320, with its emitting end located on the inner surface of the mounting frame 320 and in contact with the outer surface of the metal spherical shell 20. Thus, by providing the hemispherical mounting frame 320, the high-energy ultrasonic exciter 310 can be easily installed so that its emitting end is in contact with the outer surface of the metal spherical shell 20.

[0049] like Figure 4 , Figure 5 As shown, in some embodiments, the high-energy ultrasonic exciters 310 are evenly distributed on the mounting frame 320. This improves the homogenization and elimination effect of the high-energy ultrasonic exciters 310 on the residual stress within the metal spherical shell 20.

[0050] Figure 6 for Figure 4 Schematic diagram of the installation structure of the medium-high energy ultrasonic exciter 310; Figure 7 for Figure 4 A partial sectional view of the mounting structure of the medium-high energy ultrasonic exciter 310. (See attached diagram.) Figure 6As shown, in some embodiments, the spherical stress control device 300 further includes: a control bolt 330, which is mounted on the mounting frame 320, and the high-energy ultrasonic exciter 310 is slidably connected to the control bolt 330, sliding along the direction towards the center of the metal spherical shell 20; and a spring 340, which is sleeved on the control bolt 330, with one end of the spring 340 abutting against the head of the control bolt 330, and the other end pushing the high-energy ultrasonic exciter 310 to move towards the center of the spherical shell 320. Thus, the spring 340 can push the high-energy ultrasonic exciter 310 towards the spherical shape of the mounting frame 320, i.e., push the high-energy ultrasonic exciter 310 towards the metal spherical shell 20, so that the emitting end of the high-energy ultrasonic exciter 310 is closely attached to the outer peripheral surface of the metal spherical shell 20, thereby improving the propagation effect of ultrasonic waves and improving the reduction effect of residual stress.

[0051] Figure 8 for Figure 3 A vertical cross-sectional view of the connection structure between the spherical stress control device 300 and the housing 110. (See attached image.) Figure 8 As shown, in some embodiments, the spherical stress control device 300 further includes a height adjustment support 350, which is vertically disposed at the bottom center of the mounting frame 320. The lower end of the height adjustment support 350 is threadedly connected to the mounting frame 320, and the upper end is used to support the metal spherical shell 20. The height of the upper end of the height adjustment support 350 can be adjusted by rotating it. Thus, the height adjustment support 350 can provide support for the metal spherical shell 20 within the mounting frame 320, thereby improving the stability of the metal spherical shell 20. By adjusting the height of the upper end of the height adjustment support 350 by rotating it, the height of the metal spherical shell 20 can be adjusted, allowing the center of the metal spherical shell 20 to coincide with the center of the mounting frame 320. This improves the fit between the transmitting end of the high-energy ultrasonic exciter 310 on the mounting frame 320 and the metal spherical shell 20, thereby enhancing the residual stress reduction effect.

[0052] like Figure 1 , Figure 3 , Figure 8 As shown, in some embodiments, the workbench 100 further includes a clamping member 120, which is disposed on the housing 110 and used to clamp and fix the metal spherical shell 20 within the mounting bracket 320. Thus, the clamping member 120 can clamp and fix the metal spherical shell 20 within the mounting bracket 320, thereby improving the stability of the metal spherical shell 20 and enhancing the reduction of residual stress.

[0053] like Figure 1 , Figure 2As shown, in some embodiments, the workbench 100 further includes: legs 130, with multiple legs 130 provided for supporting the housing 110; and adjustable casters 140, with multiple adjustable casters 140 provided, each disposed at the bottom of the legs 130. Thus, the flexibility and stability of the workbench 100 can be improved by adjusting the casters 140.

[0054] The specific structure of the metal spherical shell low-stress processing and deformation feedback control device 10 of this application will be described in detail below with reference to the accompanying drawings, in a specific embodiment.

[0055] like Figure 1 , Figure 3 , Figure 8 As shown, the metal spherical shell low-stress processing and deformation feedback control device 10 of this application includes a worktable 100, a spherical stress adjustment device 300, and a detection device 200. The spherical stress adjustment device 300 is located at the center of the worktable 100 and is connected to the tabletop of the worktable 100 by eight bolts. The detection device 200 is located on the spherical shell corresponding to the channel of each exciter 310.

[0056] like Figure 1 , Figure 2 As shown, the workbench 100 is made of aluminum alloy profiles, forming the skeleton of the workbench 100, including a rectangular shell 110. Four legs 130 are provided at the four corners of the bottom of the shell 110. The bottom of the four legs 130 is equipped with height adjustment casters 140. Eight axial flow fans 150 are arranged on the four sides of the shell 110. The inward airflow can cool the spherical stress adjustment device 300. Side plates are installed on the outside of the fans 150. The side plates have heat dissipation holes. One of the side plates is equipped with a wiring terminal.

[0057] like Figure 3 As shown, the top 111 and the main body 112 of the housing 110 are separable. The housing 110 is connected to each leg 130 by four bolts. Below the top 111 is a wire groove 113, in which the exciter 310 wires of the spherical stress control device 300 are arranged. There are four lifting lugs 114 on the top 111 for easy lifting of the top 111 and the spherical stress control device 300 during debugging.

[0058] like Figure 4 , Figure 5As shown, the spherical stress control device 300 includes a mounting frame 320, a high-energy ultrasonic exciter 310, a reference flange, and a height adjustment support 350. The mounting frame 320 is a hemispherical shell 110 used to fix the high-energy ultrasonic exciter 310. Starting from the end face of the mounting frame 320, there are three layers of holes. The first layer of holes accommodates 12 high-energy ultrasonic exciters 310; the second layer, located in the middle of the mounting frame 320, accommodates 12 high-energy ultrasonic exciters 310; and the third layer, near the bottom of the mounting frame 320, accommodates 8 high-energy ultrasonic exciters 310. All three layers of holes are radially arranged with their centers facing the center of the sphere. The reference flange at the bottom of the mounting frame 320 is connected to the mounting frame 320 by six bolts. The height adjustment support 350 is divided into two parts: one part is a spherical shell support ring that contacts and supports the spherical shell; the other part is a screw that connects to the reference flange.

[0059] like Figure 7 As shown, the spherical stress control device 300 also includes: an amplitude transformer 360, control bolts 330, gaskets 370, springs 340, adjusting bolts 380, and height adjustment flanges 390. The high-energy acoustic beam exciter 310 is connected to the amplitude transformer 360 via studs, with a high-temperature resistant coupling agent applied to the connection surface. Six control bolts 330 are evenly distributed on the flange of the amplitude transformer 360, passing through the gaskets 370 and springs 340. The height adjustment flange 390 is connected to the mounting bracket 320. Two flange bolts are evenly distributed inside the height adjustment flange 390, which secure the height adjustment flange 390 to the mounting bracket 320. The adjusting bolt 380 is fixed on the flange of the amplitude rod 360. Before the control work begins, the adjusting bolt 380 is screwed in to lift the amplitude rod 360 so that its end face is separated from the metal spherical shell 20. After the metal spherical shell 20 is fixed, the adjusting bolt 380 is screwed out to ensure a tight fit between the curved end face of the amplitude rod 360 and the spherical shell.

[0060] like Figure 8 As shown, the clamping component 120 includes a clamping block 121, an annular clamping ring 122, an annular rubber pad 123, positioning blocks 124, and a clamping plate 125. In use, the metal spherical shell 20 is first placed inside the mounting bracket 320, and the annular rubber pad 123 is placed on the end face of the spherical shell to protect it from scratches. Above the annular rubber pad 123 is the annular clamping ring 122, which clamps the entire spherical shell and keeps it horizontal during clamping. Four positioning blocks 124 are mounted on the mounting bracket 320, which horizontally position the annular clamping plate 125 to prevent the end face from tilting upwards. The clamping component 120 applies clamping force to the annular clamping ring 122 through the eight clamping plates 125 and the clamping block 121, maintaining tight contact between the spherical shell and the curved surface of the amplitude transformer 360.

[0061] Figure 9 This is a schematic diagram of the detection device 200 of this application; Figure 10This is a schematic diagram of the architecture of the multi-channel high-energy ultrasound control system of this application. Figure 9 , Figure 10 As shown, 32 channels are installed in the corresponding exciter 310 control channels. As the exciter 310 eliminates internal residual stress during the control process, the multi-channel online monitoring device collects the stress state of each control channel in real time and feeds it back to the industrial control computer to realize closed-loop control of the mounting bracket 320.

[0062] After installation, the high-energy ultrasonic exciter 310 is activated through the multi-channel high-energy ultrasonic control system. Based on the stress value detected at the controlled portion of the metal spherical shell 20, the operating frequency of the high-energy ultrasonic exciter 310 is controlled within the range of 20-30kHz, injecting high-energy ultrasonic waves into the metal spherical shell 20. This drives the internal particles of the metal spherical shell 20 to vibrate along the direction of the sound beam, thereby achieving the control of residual stress in a specific direction within the material. The directivity of the sound beam allows the sound wave energy to be focused on any part of the material surface and interior, achieving localized focusing and directional reduction and homogenization of residual stress within the material. The internal residual stress is monitored and controlled in real time by the detection device 200. The expected control time is set based on the stress value at the controlled portion. The stress value monitored by the detection device 200 is input to the stress control feedback system, which then controls the multi-channel high-energy ultrasonic control system to determine whether to continue the control based on the stress value. Remove the metal spherical shell 20, test and record the stress value of the part of the metal spherical shell 20 to be adjusted in the current process, and compare it with the stress value of the last test. If the stress value decreases, fix the metal spherical shell 20 back inside the mounting bracket 320 and carry out the adjustment again.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present application has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention.
