Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3The utility model provides a kind of embodiment: a kind of device for correcting high-temperature crystal growth thermal field deformation tungsten molybdenum plate, including correction table 1, the right side outside correction table 1 is provided with extrusion assembly, by setting extrusion assembly, it is convenient to correct the deformation tungsten molybdenum plate, the upper portion of correction table 1 is provided with mounting plate 11, mounting plate 11 is provided with replacement assembly inside, by setting replacement assembly, it is convenient to replace the correction plate 12 of different size, replacement assembly lower part is fixedly connected with correction plate 12, by setting correction plate 12, it is convenient to exert pressure to the deformation tungsten molybdenum plate;

[0027] Extrusion assembly includes motor 3, motor 3 is arranged at the right side outside correction table 1, motor 3 output is fixedly connected with rotating rod 4, rotating rod 4 is rotatably connected in the inside of correction table 1, rotating rod 4 outside both sides are fixedly connected with gear 5, correction table 1 inside both sides are provided with rack plate 6, two rack plates 6 are engaged with two gears 5, two rack plates 6 are fixedly connected with guide block 7 outside, two rack plates 6 upper portion are fixedly connected with extension block 8, two rack plates 6 top are fixedly connected with mounting rod 10, two mounting rods 10 are fixedly connected with mounting plate 11 outside, the right side outside correction table 1 is fixedly connected with mounting ring 2, motor 3 is fixedly connected in the inside of mounting ring 2, by setting mounting ring 2, it is convenient to fix motor 3, the inside both sides of correction table 1 are fixedly connected with guide rod 18, two guide blocks 7 are slidably connected in the outside of two guide rods 18, by setting guide rod 18, it is convenient to move guide block 7, the upper portion both sides of correction table 1 are fixedly connected with telescopic rod 9, two telescopic rods 9 top are fixedly connected in the inside of two extension blocks 8, by setting telescopic rod 9, it plays the role of auxiliary rack plate 6 movement, the upper portion both sides of correction table 1 are provided with through-hole 17, two rack plates 6 are slidably connected in the inside of two through-holes 17, by setting through-hole 17, it is convenient to move rack plate 6.

[0028] Specifically, when the deformed tungsten-molybdenum plate is corrected, first, the deformed tungsten-molybdenum plate is placed on the upper part of the correction table 1 as a working area to provide a stable support platform for subsequent correction operations. Then, the motor 3 is started, and the motor 3 drives the rotating rod 4 fixed thereon to rotate through its output end. The rotation of the rotating rod 4 synchronously drives the two gears 5 fixed on the outside of the rotating rod 4, and the gears 5 further drive the two rack plates 6 outside through the meshing action to move downward in the vertical direction. In the process of the rack plates 6 moving downward, the mounting rod 10 fixed on the top thereof moves synchronously, thereby driving the mounting plate 11 mounted on the mounting rod 10 to also move downward. The movement of the mounting plate 11 further drives the correction plate 12 fixed on the lower part to press the deformed tungsten-molybdenum plate surface downward, thereby applying uniform extrusion pressure. Then, after the deformed tungsten-molybdenum plate is pressed tightly by the correction plate 12, the deformed tungsten-molybdenum plate is heated by using an oxyacetylene flame. The oxyacetylene flame can provide high-temperature heating to soften the metal grains of the tungsten-molybdenum plate and release the internal stress. During the heating process, the correction plate 12 continuously applies pressure, and the deformed tungsten-molybdenum plate is gradually corrected by hot pressing, such as bending and warping, until the tungsten-molybdenum plate returns to the original flat shape and can be reused. This correction method is different from the traditional manual operation mode, and the operator no longer needs to tighten each bolt 16 to apply pressure. The pressure can be quickly applied, and the pressure application process is automated and uniform. The efficiency and accuracy of manual adjustment are completely independent, and the operation efficiency is greatly improved.

[0029] Reference Figure 4 The replacement assembly includes a cross-shaped plug 13 arranged in the interior of the mounting plate 11. The bottom of the cross-shaped plug 13 is fixedly connected with the correction plate 12. The correction plate 12 is made of stainless steel material, which has excellent high-temperature resistance and can withstand the high-temperature environment generated by the oxyacetylene flame during the correction of the tungsten-molybdenum plate without deformation or damage, thereby maintaining the long service life of the correction plate 12. The interior of the mounting plate 11 is screw-connected with two bolts 16 on both sides. The interior of the mounting plate 11 is provided with a cross-shaped sliding groove 15, and the cross-shaped plug 13 is slidingly connected in the interior of the cross-shaped sliding groove 15. The cross-shaped sliding groove 15 facilitates the movement of the cross-shaped plug 13. The upper part of the cross-shaped plug 13 is provided with a threaded groove 14 on both sides. The two bolts 16 are screw-connected with the two threaded grooves 14, thereby facilitating the fixation of the correction plate 12.

[0030] Specifically, when the size of the correction plate 12 needs to be replaced, first, the two bolts 16 are removed from the threaded slots 14 on both sides of the cross-shaped insert block 13 inside the mounting plate 11. This design allows the operator to quickly loosen the fixing assembly of the correction plate 12, avoiding the tedious disassembly and assembly steps, and shortening the time for replacing the correction plate 12. Then, by moving the correction plate 12, it is removed smoothly from the cross-shaped sliding groove 15 on the lower part of the mounting plate 11, together with the cross-shaped insert block 13 fixed on the upper part. When installing the new correction plate 12, simply align the cross-shaped insert block 13 fixed on the upper part of the new correction plate 12 with the cross-shaped sliding groove 15 on the lower part of the mounting plate 11, and insert it smoothly into the sliding groove. This step ensures that the correction plate 12 can cooperate with the sliding groove, not only ensuring the stability of the correction plate 12, but also providing a reliable foundation for subsequent operations. Next, the two bolts 16 are screwed into the threaded slots 14 on both sides of the cross-shaped insert block 13 inside the mounting plate 11, completing the fixation of the new correction plate 12 and achieving the function of easily replacing the correction plate 12 with the same size as the deformed tungsten-molybdenum plate. This makes the device adaptable to tungsten-molybdenum plates of different sizes and shapes, greatly improving the applicability of the device. During the correction process, the new correction plate 12 can be adjusted according to the specific specifications of the tungsten-molybdenum plate to ensure that the applied pressure completely covers the surface of the tungsten-molybdenum plate, avoiding uneven pressure caused by the correction plate 12 being too large or too small, and improving the accuracy and consistency of the correction effect.

[0031] Working principle: When correcting the deformed tungsten-molybdenum plate, first, place the deformed tungsten-molybdenum plate on the upper part of the correction table 1. Then, start the motor 3, which rotates the rotating rod 4 fixed on the output end. The rotating rod 4 rotates the two gears 5 fixed on the outside, which moves the two toothed plates 6 meshing on the outside downward. The two toothed plates 6 move the two installation rods 10 fixed on the top synchronously, and the two installation rods 10 move the installation plate 11 fixed on the outside synchronously. The installation plate 11 moves the correction plate 12 installed on the lower part downward, so that the correction plate 12 presses the deformed tungsten-molybdenum plate. Finally, use the oxyacetylene flame to heat the deformed tungsten-molybdenum plate. The hot pressing function of the deformed tungsten-molybdenum plate is realized by the extrusion of the correction plate 12, until the deformed tungsten-molybdenum plate returns to its original shape and can be used. This realizes the convenience of correcting the deformed tungsten-molybdenum plate. Unlike the traditional method of manually tightening each bolt 16, this method can quickly apply pressure without the need for manual adjustment of each bolt 16, greatly improving the correction efficiency.

[0032] When the correction plate 12 of different size needs to be replaced, first, the two bolts 16 are taken out from the inside of the threaded grooves 14 opened on both sides of the mounting plate 11 and the cross-shaped insert block 13, then the correction plate 12 with the upper fixed cross-shaped insert block 13 is moved out from the inside of the cross-shaped sliding groove 15, and the dismounting of the correction plate 12 is completed, when the appropriate correction plate 12 is installed, the new correction plate 12 with the upper fixed cross-shaped insert block 13 is inserted into the inside of the cross-shaped sliding groove 15 opened on the lower part of the mounting plate 11, then the two bolts 16 are screwed into the inside of the threaded grooves 14 opened on both sides of the mounting plate 11 and the cross-shaped insert block 13, and the installation of the correction plate 12 is completed, the replacement of the correction plate 12 with the same size as the deformed tungsten-molybdenum plate is facilitated, the pressure applied during the correction process can completely cover the surface of the deformed tungsten-molybdenum plate, the uneven correction caused by the too large or too small correction plate 12 is avoided, and the precision of the correction effect is improved.

[0033] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
