[0002] Flange heat treatment refers to a series of processes such as heating, heat preservation, and cooling of flange pipe fittings to improve their mechanical properties and enhance their performance. Flanges are commonly used connection parts in pipeline engineering, and there are various types, including flat welding flanges, butt welding flanges, socket welding flanges, loose flanges, and threaded flanges. Different types of flanges have different connection methods and applicable occasions in use, and their heat treatment processes are also different. The process of flange heat treatment mainly includes three stages: heating, heat preservation, and cooling. According to different needs and material properties, the methods and parameters of heat treatment will be different. For example, annealing is usually used to reduce hardness, improve plasticity and toughness; normalizing is to obtain better mechanical properties; quenching and tempering are to improve hardness and wear resistance. When cooling, the outside of the flange is usually cooled, but the center of the flange cannot be cooled. Therefore, the cooling speed of the center and the outside of the flange is different, which will cause the hardness of the center and the outside of the flange to be different, resulting in overall differences.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-3 As shown, a flange heat treatment clamping tool comprises a box body 1, on which a cover plate 11 is arranged, a guide portion 12 is arranged on the cover plate 11, a connecting pipe 16 is arranged at one end of the guide portion 12, a fixing rod 13 connected to the connecting pipe 16 is arranged on the guide portion 12, the fixing rod 13 is a hollow rod, and a threaded guide groove 14 is opened therein, and the end of the fixing rod 13 is closed in a default state;

[0021] A box body 22 is disposed in communication with the side surface of the box body 1 , and a pressing block 24 is slidably disposed on the box body 22 .

[0022] Specifically, the flange is fixed on the fixing rod 13 on the cover plate 11 on the box body 1, and then the pressing block 24 on the box body 22 is stepped on with the foot to make the pressing block 24 downward and inflate the box body 1. The box body 1 is sealed, and negative pressure is formed in the box body 1. At the same time, the gas enters the connecting pipe 16, and then enters the fixing rod 13, and moves upward along the guide groove 14. When the water in the water tank 1 enters through the connecting pipe 16 and moves in the fixing rod 13, it will hit the vertical plate 18 set in the middle of the fixing rod 13, and then move upward to the top, and then move to the other side out, re-enter the guide part 12, flow back into the box body 1, and then circle on the fixing rod 13 to cool the center position of the flange.

[0023] In the above scheme, cooling water is placed through the box body 1, and the box body 1 is closed by the cover plate 11 on the box body 1, and is used to place the guide part 12. The water in the box body 1 is connected to the connecting pipe 16 through the guide part 12 and the connecting pipe 16, and flows into the fixed rod 13 on the guide part 12 to cool the fixed rod 13. At the same time, the flange is mounted on the fixed rod 13 to cool the center of the flange. The box body 1 is inflated by pressing through the box body 22 and the pressing block 24 on the side of the box body 1. It should be noted that the box body 1 is sealed as a whole, and there is only one connecting pipe 16 and one outlet, so water is discharged by negative pressure.

[0024] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, a plurality of elastic members 27 arranged in a linear array are disposed at the bottom of the box body 22 , a slide plate 26 is disposed on the elastic members 27 , and the other end of the elastic member 27 is fixedly disposed on the slide plate 26 .

[0025] Specifically, when the pressing block 24 is pressed downward, the sliding plate 26 will be pushed downward, and the sliding plate 26 will push the gas into the box body 1. When the pressing block 24 moves downward, it will abut against the elastic member 27. After pressing once, the pressing block 24 is released and pushed upward by the elastic member 27.

[0026] It should be noted that the upper layer of the edge of the slide plate 26 is a thin layer, and the bottom layer is a thick layer, so when the slide plate 26 moves downward, the space at the bottom of the box body 22 and the box body 1 are in a sealed state, and when it moves upward, the seal is released.

[0027] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, a fixed plate 15 and a movable plate 19 are respectively provided on the cover plate 11 , and a movable hoop 18 is provided on both the fixed plate 15 and the movable plate 19 .

[0028] Furthermore, a slide groove 111 is provided on the cover plate 11 , and the movable plate 19 is slidably disposed in the slide groove 111 .

[0029] Furthermore, a connecting plate 191 is provided on the cover plate 11 , a screw rod 20 is threadedly provided on the connecting plate 191 , a handle 21 is provided on the screw rod 20 , and one end of the screw rod 20 is pushed against the movable plate 19 .

[0030] Specifically, when the flange is sleeved on the fixing rod 13, the first step of fixing is performed, and then the handle 21 is turned to drive the screw 20 to rotate, the screw 20 rotates on the connecting plate 191, and then pushes the movable plate 19 to move, and pushes the movable hoop 18 to move toward the flange to fix the flange.

[0031] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, a connecting pipe 25 is provided between the box body 22 and the housing 1 .

[0032] Specifically, when the pressing block 24 is pressed downward, the sliding plate 26 is pushed downward, and the sliding plate 26 pushes the gas into the connecting pipe 25 and then into the box body 1.

[0033] Working principle: When the flange is set on the fixing rod 13, the first step is to fix it, and then the handle 21 is turned to drive the screw 20 to rotate. The screw 20 rotates on the connecting plate 191, and then the movable plate 19 is pushed to move, and the movable hoop 18 is pushed to move toward the flange to fix the flange. The pressing block 24 is pressed downward, and the slide plate 26 is pushed downward. After the slide plate 26 moves downward, the gas is pushed into the box body 1. When the pressing block 24 moves downward, it will resist the elastic The pressing block 24 is released after pressing once, and is pushed upward by the elastic member 27, so that the air is reciprocated and the box body 1 is sealed, and a negative pressure is formed in the box body 1. At the same time, the gas enters the connecting pipe 16, and then enters the fixed rod 13, and moves upward along the guide groove 14. When the water moves in the fixed rod 13, it will hit the vertical plate set in the middle of the fixed rod 13, and then move upward to the top, and then move to the other side, re-enter the guide part 12, and flow back into the box body 1.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
