[0002] Steel plates are flat steel materials cast from molten steel and pressed after cooling. They are flat and rectangular, and can be directly rolled or cut from wide steel strips. Steel plates are classified by thickness into thin steel plates < 4 mm (the thinnest is 0.2 mm), medium-thick steel plates of 4 - 60 mm, and extra-thick steel plates of 60 - 115 mm; steel plates are classified by rolling into hot-rolled and cold-rolled.

[0003] In the field of metal material processing, strong compressive steel plates are widely used due to their excellent mechanical properties. However, residual stress often occurs during the processing of steel plates, affecting their performance and service life.

Currently, the commonly used methods for removing residual stress mainly include heat treatment and mechanical vibration method. Heat treatment releases stress by heating and slow cooling, but the processing time is long and it may cause changes in material properties.

Specific implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 , a device for quickly removing the residual stress of a strong compressive steel plate in this embodiment, includes a fixed frame 1. Both the left and right ends of the upper surface of the fixed frame 1 are fixed with load-bearing plates 2. The upper surface of the load-bearing plates 2 is fixed with the same top plate 3. The upper surface of the top plate 3 is provided with a vibration mechanism 4 for applying high-frequency vibration to the steel plate. The bottom of the right side of the fixed frame 1 is provided with a fixing mechanism 5 for fixing the steel plate, and the left side of the fixed frame 1 is provided with a controller 6.

[0031] In this embodiment, a pressure sensor is fixed in the middle of the upper surface of the fixed frame 1, and temperature sensors are fixed at both the left and right ends of the upper surface of the fixed frame 1.

[0032] It should be noted that the set temperature sensor and pressure sensor can monitor the temperature and pressure changes during the processing in real time and transmit the data to the controller 6. The control system in the controller 6 adjusts the parameters of the high-frequency vibrator 45 according to the real-time monitored data to achieve more accurate stress removal.

[0033] Please refer to Figure 2, in order to fix the steel plate, the fixing mechanism 5 in this embodiment includes a driving motor 51, a bidirectional screw 52, two screw sleeves 53, two connecting plates 54, two telescopic columns 55, two linkage blocks 56 and two fixing plates 57. The driving motor 51 is fixed at the bottom on the right side of the fixing frame 1. The bidirectional screw 52 is rotatably connected between the opposite sides of the left and right inner side walls of the fixing frame 1 through bearings at the bottom. The output shaft of the driving motor 51 penetrates through the right side wall of the inner cavity of the fixing frame 1 and extends into the inner cavity of the fixing frame 1 and is fixed to the bidirectional screw 52. The screw sleeve 53 is threadedly connected with the bidirectional screw 52. By starting the driving motor 51 through the controller 6, the output shaft of the driving motor 51 rotates to drive the bidirectional screw 52 to rotate. The rotation of the bidirectional screw 52 causes the screw sleeve 53 threadedly connected to its surface to move. The connecting plate 54 is fixed on the upper surface of the screw sleeve 53. Two telescopic columns 55 are fixed at the top of the opposite sides of the left and right inner side walls of the fixing frame 1. The linkage block 56 is fixed on the upper surface of the connecting plate 54. The other side of the telescopic column 55 is fixed to the linkage block 56. The fixing plate 57 is fixed on the upper surface of the linkage block 56. The two screw sleeves 53 move towards each other. The movement of the two screw sleeves 53 drives the connecting plate 54 to move. The movement of the connecting plate 54 drives the linkage block 56 to move. The movement of the linkage block 56 drives the telescopic column 55 to extend and causes the fixing plate 57 to move. The relative movement of the two fixing plates 57 can fix the steel plate.

[0034] Among them, a protective box is provided on the outer surface of the driving motor 51. The two screw sleeves 53 are symmetrically distributed on the left and right sides of the vertical central axis of the bidirectional screw 52. A limiting rod is fixed at the top of the opposite sides of the left and right inner side walls of the fixing frame 1 and above the telescopic column 55. The fixing plate 57 is slidably connected with the limiting rod.

[0035] In this embodiment, the upper surface of the fixing plate 57 penetrates through the inner top wall of the fixing frame 1 and extends to the upper side of the fixing frame 1. A guiding hole adapted to the size of the fixing plate 57 is provided on the upper surface of the fixing frame 1. Anti-slip plates are fixed on the opposite sides of the two fixing plates 57. The anti-slip plates are rubber plates.

[0036] It should be noted that a laser rangefinder is provided on the outer surface of the fixing frame 1 for real-time monitoring of the deformation of the steel plate. The data of the laser rangefinder is also transmitted to the controller 6 to more precisely control the vibration process and prevent over-treatment or under-treatment.

[0037] Please refer to Figures 3 to 4, in order to quickly remove the stress in the steel plate, the vibration mechanism 4 in this embodiment includes a protective frame 41, an electric push rod 42, a movable plate 43, a mounting seat 44 and a high-frequency vibrator 45. The protective frame 41 is fixed on the upper surface of the fixed frame 1. The electric push rod 42 is fixed on the inner top wall of the protective frame 41. The piston rod of the electric push rod 42 penetrates through the top plate 3 and extends to the lower side of the top plate 3 and is fixed to the movable plate 43. By starting the electric push rod 42 through the controller 6, the piston rod of the electric push rod 42 extends, thereby pushing the movable plate 43 to move downward. The mounting seat 44 is fixed on the lower surface of the movable plate 43, and the high-frequency vibrator 45 is fixed in the inner cavity of the mounting seat 44. The controller 6 can control the vibration frequency and amplitude of the high-frequency vibrator 45, so that the high-frequency vibration applied to the steel plate by the high-frequency vibrator 45 can quickly release the residual stress.

[0038] In this embodiment, the number of the mounting seats 44 is not less than two. The mounting seats 44 not less than two are evenly distributed on the lower surface of the movable plate 43. Limiting grooves are formed on the opposite sides of the two bearing plates 2. Limiting blocks are fixed on the left and right sides of the movable plate 43. The limiting blocks move linearly up and down in the inner cavity of the limiting grooves. The limiting blocks fixed on the left and right sides of the movable plate 43 move downward in the inner cavity of the limiting grooves, which can limit the movement of the movable plate 43.

[0039] It should be noted that the high-frequency vibrator 45 can be replaced by an ultrasonic vibrator to achieve more precise vibration control; the control system can adopt different types of controllers 6 such as PLC or microprocessor to adapt to different application scenarios and requirements.

[0040] It can be understood that the high-frequency vibrator 45 adopts a modular design, which is convenient for replacing or increasing the number of high-frequency vibrators 45 according to needs.

[0041] The working principle of the above embodiment is as follows:

[0042] (1) When removing the stress of the high-strength steel plate, first place the steel plate on the upper surface of the fixed frame 1 and on the upper surface of the pressure sensor, and then start the drive motor 51 through the controller 6. The output shaft of the drive motor 51 rotates to drive the bidirectional screw 52 to rotate. The rotation of the bidirectional screw 52 causes the nut sleeve 53 threadedly connected to its surface to move. At this time, the two nut sleeves 53 move relatively. The movement of the two nut sleeves 53 drives the connecting plate 54 to move. The movement of the connecting plate 54 drives the linkage block 56 to move. The movement of the linkage block 56 drives the telescopic column 55 to extend and makes the fixed plate 57 move. The relative movement of the two fixed plates 57 can fix the steel plate.

[0043] (2) Then, start the electric push rod 42 through the controller 6. The piston rod of the electric push rod 42 extends, thereby pushing the movable plate 43 to move downward. At this time, the limit blocks fixed on the left and right sides of the movable plate 43 move downward in the inner cavity of the limit groove, which can limit the movement of the movable plate 43. After the movable plate 43 moves to an appropriate height, the high-frequency vibrator 45 can be controlled through the controller 6. The controller 6 can control the vibration frequency and amplitude of the high-frequency vibrator 45, so that the high-frequency vibration applied to the steel plate by the high-frequency vibrator 45 can quickly release the residual stress. The set temperature sensor and pressure sensor can monitor the temperature and pressure changes during the processing in real time and transmit the data to the controller 6. The control system in the controller 6 adjusts the parameters of the high-frequency vibrator 45 according to the real-time monitored data to achieve more precise stress removal.
