Description

Technical Field

[0001] The invention relates to the technical field of seamless square tube processing, in particular to a stainless steel nickel alloy seamless square tube forming processing die for nuclear power semiconductor military industry aerospace. Background Art

[0002] Stainless steel nickel alloy seamless square tube is a metal product, which is mainly composed of stainless steel and nickel alloy, so it has excellent corrosion resistance and wear resistance. The characteristics of seamless square tube are that its cross section is square and there is no seam around it, which gives it higher structural strength and better fluid transmission performance. Since stainless steel nickel alloy seamless square tube combines the corrosion resistance of stainless steel with the high strength and high temperature resistance of nickel alloy, it has excellent performance in various applications, so it is widely used in nuclear power, semiconductor, military industry, aerospace and other fields.

[0003] In the prior art, the forming method of stainless steel nickel alloy seamless square tubes generally adopts hot extrusion or cold drawing process. Hot extrusion is to heat the tube blank to a high temperature and extrude the tube blank into a seamless tube through an extruder. This method is suitable for manufacturing large-caliber and thick-walled seamless tubes and has high production efficiency. Cold drawing is to draw the tube blank through a die at room temperature into a seamless tube. It is suitable for manufacturing small-caliber and thin-walled seamless tubes. Although the production efficiency is relatively low, the finished product has a smooth surface and high dimensional accuracy. However, these two processes have good forming effects only within the applicable caliber and wall thickness range, and have poor applicability and cannot meet various production needs. Once the square tube model changes, there may be large differences in its caliber and wall thickness, and the equipment and process need to be replaced before the forming process can be carried out.

The output shaft of the drive motor 303 is fixedly connected to the bidirectional screw rod 304 through a coupling, and one end of the bidirectional screw rod 304 is movable with the inner wall of the box shell 301 through a bearing. The movable control box 3 also includes a moving block 305, the moving block 305 and the bidirectional screw rod 304 form a through structure, and the inner wall of the moving block 305 is threadedly connected to the outer wall of the bidirectional screw rod 304, and an upper rolling mechanism 4 is arranged at the bottom of the movable control box 3, and the upper rolling mechanism 4 includes a left frame 401 and a right frame 402, the left frame 401 is fixedly connected to the bottom of one moving block 305, and the right frame 402 is fixedly connected to the bottom of the other moving block 305, and the upper rolling mechanism 4 also includes a servo motor 403, a heating roller assembly 404 and a roller mold 405, the servo motor 403 is fixedly installed on the inner side of the left frame 401, and the output of the servo motor 403 The output shaft is fixedly connected to a heating roller assembly 404 through a coupling, and one end of the heating roller assembly 404 is movably connected to the inner surface of the right frame 402 through a bearing, a roller mold 405 is sleeved on the heating roller assembly 404, and the heating roller assembly 404 includes a left heating roller 4041 and a left limiter 4042, one end of the left heating roller 4041 is connected to the servo motor 403, and the other end of the left heating roller 4041 is provided with a square groove, and the outer wall of the left heating roller 4041 is welded with a left limiter 4042, the heating roller assembly 404 also includes a right heating roller 4043, a right limiter 4044 and a square plug 4045, one end of the right heating roller 4043 It is connected to the right frame 402, and the outer wall of the right heating roller 4043 is welded with a right limit piece 4044, and the other end of the right heating roller 4043 is fixedly connected with a square plug rod 4045, the right heating roller 4043 and the square plug rod 4045 form an integrated structure, and the right heating roller 4043 forms a plug-in structure with the left heating roller 4041 through the square plug rod 4045 and the square groove, the outer surface of the square plug rod 4045 is completely fitted with the inner surface of the square groove, and the shape and size of the square plug rod 4045 and the shape and size of the square groove match each other, the inner bottom wall of the mold box 1 is fixedly connected with a fixed control box 5, and the top of the fixed control box 5 is provided with a lower rolling mechanism 6.

[0022] The specific operation is as follows: the operator starts the upper rolling mechanism 4 and the lower rolling mechanism 6, and the servo motor 403 of the upper rolling mechanism 4 will drive the heating roller assembly 404 to rotate, thereby driving the roller mold 405 to rotate, and in this process, the heating roller assembly 404 is continuously heated and transfers heat to the roller mold 405. The operation of the lower rolling mechanism 6 is the same as that of the upper rolling mechanism 4, and the round tube is guided by the traction device and passes between the upper rolling mechanism 4 and the lower rolling mechanism 6, specifically between the two roller molds 405, and is rolled and transformed from a round tube into a square tube. The mold is simple to operate and can easily realize the rolling of seamless square tubes, and is particularly suitable for the production and preparation of seamless square tubes of stainless steel and nickel alloys. At the same time, the mold is also provided with a movable control box 3, which drives the two-way screw 304 to rotate through the driving motor 303, and cooperates with the inner wall of the box shell 301 to limit the moving trajectory of the moving block 305, so that the two moving blocks 305 can move towards or away from each other under the rotation drive of the two-way screw 304, thereby driving the left frame 401 and the right frame 402 to move towards or away from each other. When the roller mold 405 needs to be replaced, first release the connection effect between the left limiter 4042 and the right limiter 4044 and the roller mold 405, that is, unscrew the bolts used for fixing, and then control the left frame 401 and the right frame 402 to move away from each other through the driving motor 303, so that the square plug 4045 of the right heating roller 4043 is pulled out from the square groove of the left heating roller 4041, so that the roller mold 405 is separated from the heating roller assembly 404, and then a new heating roller assembly 404 is installed. The roller assembly 404 uses the driving motor 303 to control the left frame 401 and the right frame 402 to move toward each other, inserts the square plug rod 4045 into the square groove, and docks the right heating roller 4043 with the left heating roller 4041 until the left limiter 4042 and the right limiter 4044 respectively reach the two sides of the roller mold 405, the motor stops moving, and then the left limiter 4042 and the right limiter 4044 are respectively connected to the two sides of the roller mold 405 by bolts. Similarly, the lower rolling mechanism 6 can be disassembled and replaced, and the upper rolling mechanism 4 can be controlled to rise and fall in conjunction with the cylinder 2, so that the spacing between the upper rolling mechanism 4 and the lower rolling mechanism 6 can be adjusted. Through the coordinated use of the above structure, the forming mold has the function of precise size control and adjustment, thereby enhancing the adaptability of the mold and being able to adapt to the processing of various types of seamless square tubes.

[0023] like Figure 1-Figure 3As shown, the preheating bin 7 is fixed to the left outer wall of the mold box 1, and the inner wall of the preheating bin 7 is fixedly installed with a heating wire, and the left wall of the preheating bin 7 is provided with an inlet 8, the cooling bin 9 is fixed to the right outer wall of the mold box 1, and the right wall of the cooling bin 9 is provided with an outlet 10, and the outer wall of the cooling bin 9 is connected with an air cooling mechanism 11, and the air cooling mechanism 11 includes an air pump 1101, an exhaust pipe 1102 and an air return pipe 1103, and the air pump 1101 is installed on the top of the cooling bin 9, and the air inlet of the air pump 1101 is fixedly connected with the exhaust pipe 1102 , and the bottom end of the exhaust pipe 1102 is connected to the top of the cooling bin 9, the air outlet of the air pump 1101 is fixedly connected to the return air pipe 1103, the air cooling mechanism 11 also includes a refrigeration water tank 1104 and an air outlet pipe 1105, the refrigeration water tank 1104 is installed at the bottom of the cooling bin 9, and the outer wall of the refrigeration water tank 1104 is connected to one end of the return air pipe 1103, the top of the refrigeration water tank 1104 is fixedly connected to the air outlet pipe 1105, and the top end of the air outlet pipe 1105 passes through the bottom of the cooling bin 9 and extends to the interior of the cooling bin 9.

[0024] The specific operation is as follows: before the round tube enters the mold box 1, it will first enter the preheating bin 7 through the tube inlet 8, and will be preheated by the heating wire on the inner wall of the preheating bin 7 to avoid sudden heating during subsequent heating roller rolling, which helps to improve the quality of the finished square tube. After rolling, the square tube will enter the cooling bin 9 for cooling. During this process, the air cooling mechanism 11 continues to operate, and the air pump 1101 extracts the air in the cooling bin 9 through the exhaust pipe 1102, and sends it into the refrigeration water tank 1104 through the return air pipe 1103. The air enters the water and is cooled by the water, and then is discharged through the outlet pipe 1105 and re-enters the cooling bin 9 to form an air cooling cycle. Moreover, since the refrigeration water tank 1104 can always cool the water in the box, the water in the refrigeration water tank 1104 can always maintain a low temperature state, and continuously cool the newly entering air, which helps to maintain a good cooling effect, so that it is suitable for continuous production work. Through cooling, the formed square tube is not easy to deform, and the risk of high temperature burns is avoided. Finally, the square tube finished product is output from the outlet 10.

[0025] In summary, combined Figure 1-Figure 6As shown, the working principle of the stainless steel nickel alloy seamless square tube forming processing die for nuclear power semiconductor military aerospace is as follows: first, the round tube enters the preheating chamber 7 through the tube inlet 8, and is preheated by the heating wire on the inner wall of the preheating chamber 7. Then, the round tube enters the mold box 1, and the upper rolling mechanism 4 and the lower rolling mechanism 6 in the mold box 1 are started at the same time. The servo motor 403 drives the heating roller assembly 404 to rotate, thereby driving the roller mold 405 to rotate. During this process, the heating roller assembly 404 is continuously heated and transfers heat to the roller mold 405. The lower rolling mechanism 6 operates in conjunction with the upper rolling mechanism. Similarly, the round tube passes through between the two roller molds 405, is rolled and transformed into a square tube, and after rolling, enters the cooling bin 9 for cooling. During the cooling process, the air pump 1101 extracts the air in the cooling bin 9 through the exhaust pipe 1102, and sends it to the refrigeration water tank 1104 through the return air pipe 1103. The air enters the water, is cooled by the water, and is then discharged through the outlet pipe 1105 and re-enters the cooling bin 9 to form an air-cooled cycle. At the same time, the refrigeration water tank 1104 will continue to cool the water in the box, and finally the square tube product is output from the outlet 10.

[0026] According to production needs, the user can also replace the roller mold 405. First, the connection effect of the left limit piece 4042 and the right limit piece 4044 on the roller mold 405 is released, and then the left frame 401 and the right frame 402 are controlled by the driving motor 303 to move in opposite directions, so that the square plug rod 4045 of the right heating roller 4043 is pulled out from the square groove of the left heating roller 4041. After the roller mold 405 is removed, a new heating roller assembly 404 is installed, and the driving motor 303 is used to control the left frame 401 and the right frame 402 to move toward each other, and the square plug rod 4045 is reinserted into the square groove, so that the right heating roller 4043 is docked with the left heating roller 4041, until the left limit piece 4042 and the right limit piece 4044 respectively reach the two sides of the roller mold 405, the motor stops moving, and then the left limit piece 4042 and the right limit piece 4044 are respectively fixed to the two sides of the roller mold 405 by bolts. Similarly, the lower rolling mechanism 6 can be disassembled and replaced, and the upper rolling mechanism 4 can be raised and lowered by cooperating with the cylinder 2, and the distance between the upper rolling mechanism 4 and the lower rolling mechanism 6 can be reasonably adjusted to complete the replacement of the roller mold 405.
