When performing flaw detection on some titanium alloy forged tubes that contain magnetic metals such as iron and nickel, the pressure of the pressure sensor can also be used to determine whether the distribution of magnetic metals in the forged tube is uniform.

[0043] In a specific implementation, an air inlet is provided at the bottom of the workbench 1 , and the air inlet is connected to an input end of the fan 22 .

[0044] Working principle of the present invention: When the present invention is in use, first, the forged tube 2 made of titanium alloy is placed in the through groove so that the two rollers 6 support the forged tube 2, and then the abutment assembly is moved to the end of the forged tube 2 close to the bracket 14. At this time, the four electric sliders 18 are controlled to slide outward at the same time, so that the electric slider 18 drives the connecting block 19 to move toward the direction close to the inner wall of the forged tube 2 through the connecting slide column 20. As the connecting block 19 moves, the abutment wheel 17 will abut against the inner wall of the forged tube 2. At this time, the forged tube 2 can be stably placed through the abutment assembly and the roller 6.

[0045] After the forging tube 2 is placed, the motor 3 is turned on so that the motor 3 drives the roller 6 to rotate through the belt 4 and the transmission wheel 5. After the roller 6 rotates, it drives the forging tube 2 to rotate. When the forging tube 2 rotates, the friction force applied by the abutment wheel 17 to the inner wall of the forging tube 2 drives the cross 15 to rotate through the abutment wheel 17. The rotation of the cross 15 drives the screw rod 11 to rotate. When the screw rod 11 rotates, it will rotate with the second support plate 10 to achieve the feeding of the screw rod 11. During the movement of the screw rod 11, the abutment wheel 17 will also roll with the rotation of the screw rod 11. In this process, the abutment wheel 17 will roll on the inner wall of the forging tube 2. Since the rotation axis of the abutment wheel 17 is perpendicular to the rotation axis of the forging tube 2, during the rotation of the forging tube 2, the lateral friction force of the wheel surface of the abutment wheel 17 drives the cross 15 to rotate, and then the rotation of the cross 15 drives the screw rod 11 to rotate.

[0046] At the same time, during the movement of the screw rod 11, the rotation of the screw rod 11 will drive the connecting disk 12 to rotate. During the rotation of the connecting disk 12, the rotating block at the end of the connecting drive rod 35 will rotate in the rotating groove 36. When the screw rod 11 moves, it will drive the U-shaped rod 8 to move. The movement of the U-shaped rod 8 will then drive the installation box body 7 to move. During the movement of the installation box body 7, the inner and outer walls of the forging pipe 2 can be polished at the same time by the friction block 31. After the installation box body 7 moves to the end of the workbench 1 where the fixed column 16 is located, the motor 3 is controlled to reverse. At this time, the forging pipe 2 can be effectively inspected by the flaw detection head 32 inside the installation box body 7.

[0047] Through the forward and reverse rotation of the motor 3, in the process of the installation box body 7 moving from the first support plate 9 toward the fixed column 16, the inner wall and the outer wall of the forged tube 2 are simultaneously polished, which is beneficial to avoid the presence of impurities on the side wall of the forged tube 2 and thus affecting the accuracy of flaw detection. In the process of the installation box body 7 moving from the fixed column 16 toward the first support plate 9, the inner and outer walls of the forged tube 2 can be effectively flaw detected at the same time. Through a reciprocating motion of the installation box body 7, the grinding of the forged tube 2 and the flaw detection of the inner and outer sides of the forged tube 2 can be effectively realized, which effectively ensures the accuracy of flaw detection of the titanium alloy forged tube 2 and also improves the efficiency of flaw detection.

[0048] In the process of the installation box body 7 moving from the first support plate 9 toward the fixed column 16, by controlling the magnetic poles of the second electromagnets 30 inside the two installation box bodies 7, the magnetic poles of the two second electromagnets 30 that are close to each other are set oppositely, and the magnetic force of the two second electromagnets 30 is used to make the two installation box bodies 7 move in the direction of approaching each other, so that the two installation box bodies 7 are respectively abutted against the inner wall and the outer wall of the forging pipe 2. At the same time, the magnetic force of the second electromagnet 30 can effectively improve the clamping force of the installation box body 7 on the forging pipe 2. When the inner wall and the outer wall of the forging pipe 2 are polished at the same time, the grinding efficiency can be improved by increasing the pressure. In the process of the two installation box bodies 7 approaching each other, the limit wheel 25 will effectively rotate on the inner wall of the forging pipe 2.

[0049] In the process of the installation box body 7 moving from the first support plate 9 toward the fixed column 16, the magnetic poles of the first electromagnet 27 and the second electromagnet 30 located inside the same installation box body 7 at one end close to each other are also set oppositely. At this time, the magnetic force between the first electromagnet 27 and the second electromagnet 30 is used to make the first electromagnet 27 move in the direction close to the second electromagnet 30. In this process, the first electromagnet 27 will drive the first slider 26 to move in the direction of the second electromagnet 30. When the first slider 26 moves, it will drive the gear 29 to rotate through the rack at the bottom of the air. The gear 29 moves the second slider 28 in the direction away from the second electromagnet 30 through the rack at the top of the second slider 28, thereby realizing the storage of the flaw detection head 32, so that the flaw detection head 32 is stored in the installation box body 7, which is conducive to avoiding dust sticking to the flaw detection head 32 during the grinding of the forged pipe 2, thereby affecting the accuracy of flaw detection.

[0050] During the grinding process of the forged pipe 2 , the fan 22 is turned on, and the dust generated by grinding inside the forged pipe 2 is blown out by the wind blown out by the fan 22 through the wind outlet chute 23 .

[0051] As the motor 3 rotates, the contact switch 21 on the cross 15 will abut against the fixing column 16, and then the contact switch 21 will control the motor 3 to reverse, control the first electromagnet 27 to change the magnetic pole, and control the fan 22 to turn off.

[0052] After the motor 3 rotates in reverse, it will drive the screw rod 11 to rotate in the opposite direction through the abutment assembly, thereby causing the installation box body 7 to move from the fixing column 16 toward the first support plate 9, thereby realizing the start of the return work of the installation box body 7.

[0053] After the first electromagnet 27 changes its magnetic pole, the first electromagnet 27 and the second electromagnet 30 will move away from each other due to the repulsive force. At this time, the first electromagnet 27 will drive the first slider 26 to move in the direction away from the forged pipe 2, and then the flaw detection head 32 will move to the side of the forged pipe 2, and the forged pipe 2 can be effectively detected by the flaw detection head 32.

[0054] By setting the pressure sensor inside the L-shaped plate 24, during the return process of the installation box body 7, the attraction between the installation box bodies 7 is in a stable state. During the return process, the force it receives is the magnetic force applied between the two second electromagnets 30, as well as the rolling force and friction force between the limit wheel 25 and the forged tube 2. Therefore, the force received by the pressure sensor should be in a stable state, and the fluctuation of the force is within a certain range. When performing flaw detection on some titanium alloy forged tubes 2 that do not contain magnetic metals such as iron and nickel, the real-time pressure fluctuation of the pressure sensor can also be used to determine whether impurity metals are mixed in the forged tube 2. When magnetic metals are mixed in the forged tube 2, the second electromagnet 30 will attract the magnetic metals, which will cause the pressure of the pressure sensor to change. When performing flaw detection on some titanium alloy forged tubes 2 that contain magnetic metals such as iron and nickel, the pressure of the pressure sensor can also be used to determine whether the distribution of magnetic metals in the forged tube 2 is uniform.

[0055] By setting the two second electromagnets 30, by changing the magnetic poles of the two second electromagnets 30, when the two second electromagnets 30 attract each other, the two fixed box bodies 33 will slide relative to the limit slider 34, thereby making the two installation box bodies 7 approach each other; when the two second electromagnets 30 repel each other, the two fixed box bodies 33 will slide relative to the limit slider 34, thereby making the two installation box bodies 7 move away from each other.

[0056] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
