Description

Technical Field

[0001] This invention relates to the field of testing Ti65 titanium alloy seamless pipes, specifically to a device for testing the water and air pressure of Ti65 titanium alloy seamless pipes. Background Technology

[0002] Ti65 titanium alloy can be made into seamless tubing. This tubing has high mechanical properties, excellent stamping performance, and can be welded in various ways. The strength of the welded joint can reach 90% of the strength of the base metal, and it also has good machinability.

[0003] After processing, Ti65 titanium alloy seamless pipes need to be tested for water pressure and air pressure performance. When performing various pressure tests on Ti65 titanium alloy seamless pipes, pressure sensors are generally used to detect the pipe pressure and detect whether the pipe is leaking by detecting pressure changes. However, some pipes cannot withstand the pressure during the test and do not break, but instead show a certain degree of bulging and deformation. Pressure sensors cannot detect this. Therefore, it is necessary to propose a water pressure and air pressure testing device for Ti65 titanium alloy seamless pipes. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a water pressure and air pressure testing device for seamless Ti65 titanium alloy pipes.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: a water pressure and air pressure testing device for Ti65 titanium alloy seamless pipes, including a mounting base, a support plate fixedly mounted on the mounting base, a rotating rod rotatably connected to the support plate via a bearing, a threaded hole on the rotating rod, a threaded rod threadedly connected to the threaded hole, a first clamping seat rotatably connected to the threaded rod via a bearing, a second clamping seat fixedly connected to the rotating rod, an injection assembly on the second clamping seat, a pressure sensor fixedly mounted on the second clamping seat, a drive assembly fixedly mounted on the mounting base, a first fixing seat fixedly mounted on the upper surface of the mounting base, a laser light curtain emitter fixedly mounted on the first fixing seat, a fixing frame fixedly mounted on the outer wall of the mounting base, a rectangular hole penetrating the fixing frame, a rectangular rod slidably connected within the rectangular hole, a second fixing seat fixedly mounted at one end of the rectangular rod, an ultrasonic crack detector fixedly mounted on the second fixing seat, a spring sleeved on the rectangular rod, and both ends of the spring fixedly connected to the second fixing seat and the fixing frame, respectively.

[0006] Specifically, the drive assembly includes a mounting slot, which is formed on the upper surface of the mounting base. A dual-head drive motor is fixedly installed in the mounting slot. Both ends of the dual-head drive motor are fixedly mounted with drive rods via couplings. Drive wheels are fixedly installed on the drive rods, and the two drive wheels abut against their respective rotating rods.

[0007] Specifically, the upper surface of the mounting base has two grooves.

[0008] Specifically, a limiting hole is provided on the rotating rod, and a limiting rod is slidably connected in the limiting hole. Both ends of the limiting rod extend outside the rotating rod, and one end of the limiting rod is fixedly connected to the first clamping seat.

[0009] Specifically, the injection assembly includes a threaded groove on the outer wall of the rotating rod, a connecting hole is formed through the threaded groove, one end of the connecting hole is set to penetrate the second clamping seat, and an electromagnetic valve is fixedly installed on the inner wall of the connecting hole.

[0010] Specifically, the end of the threaded rod away from the first clamping seat extends out of the rotating rod, and a handle is fixedly connected to the end of the threaded rod away from the first clamping seat.

[0011] Specifically, a limiting plate is fixedly connected to the end of the rectangular rod away from the second fixed seat.

[0012] The beneficial effects of this invention are as follows: The device for testing the water and air pressure of Ti65 titanium alloy seamless pipes, as described in this invention, involves rotating a threaded rod to drive a first clamping seat. The first and second clamping seats clamp pipes of the same specifications. Air is then injected into the pipe, and a rotating rod drives the clamping seats and the pipe to rotate. At this time, the light curtain emitted by the laser light curtain emitter coincides with its edge. If there are bulges on the pipe surface, they will block the light curtain, causing it to bend and become easier to detect. Simultaneously, a spring pushes an ultrasonic crack detector against the pipe to detect internal cracks. After the air pressure test is completed, the air pressure is released, and clean water is injected for repeated testing, thus comprehensively detecting changes in the pipe during air and water pressure testing.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: A water and air pressure testing device for Ti65 titanium alloy seamless pipes includes a mounting base 1, a support plate 2 fixedly mounted on the mounting base 1, a rotating rod 3 rotatably connected to the support plate 2 via a bearing, a threaded hole 4 on the rotating rod 3, a threaded rod 5 internally threaded into the threaded hole 4, a first clamping seat 6 rotatably connected to the threaded rod 5 via a bearing, a second clamping seat 23 fixedly connected to the rotating rod 3, a material injection assembly provided on the second clamping seat 23, a pressure sensor 24 fixedly mounted on the second clamping seat 23, and a... The drive assembly has a first fixed seat 7 fixedly mounted on the upper surface of the mounting base 1. A laser light curtain emitter 8 is fixedly mounted on the first fixed seat 7. A fixed frame 9 is fixedly mounted on the outer side wall of the mounting base 1. A rectangular hole 10 is opened through the fixed frame 9. A rectangular rod 11 is slidably connected in the rectangular hole 10. A second fixed seat 12 is fixedly mounted on one end of the rectangular rod 11. An ultrasonic crack detector 13 is fixedly mounted on the second fixed seat 12. A spring 14 is sleeved on the rectangular rod 11. The two ends of the spring 14 are fixedly connected to the second fixed seat 12 and the fixed frame 9, respectively. When using it, the following steps are included: Step 1: Place pipes of the same specifications between the first clamping seat 6 and the second clamping seat 23, then hold the limiting rod 20 to prevent the rotating rod 3 from rotating. Then rotate the threaded rod 5. The threaded rod 5 moves in the threaded hole 4 and pushes the first clamping seat 6 to move. The first clamping seat 6 and the second clamping seat 23 clamp, fix and seal the pipes. The second step is to connect the injection assembly to the external air compressor and inject air into the pipe through the injection assembly. The pressure sensor 24 monitors the air pressure inside the pipe until the air pressure inside the pipe reaches 1.15 times the design pressure that the pipe can withstand. Then, the injection assembly is closed and disconnected from the external air compressor. Third step: At this time, start the dual-head drive motor 16. The dual-head drive motor 16 drives the two drive rods 17 to rotate. The two drive rods 17 drive the two drive wheels 18 to rotate. The two drive wheels 18 drive the two drive rods 3 to rotate through the mutual abutment of the drive rods 3. One of the drive rods 3 drives the first clamping seat 6 to rotate through the limiting hole 19 and the limiting rod 20. The other drive rod 3 drives the second clamping seat 23 to rotate. The first clamping seat 6 and the second clamping seat 23 drive the pipe to rotate synchronously. Fourth step: Spring 14 pushes the second fixed seat 12 under the support of the fixed frame 9, so that the second fixed seat 12 drives the ultrasonic crack detector 13 to abut against the pipe. Then, when the pipe rotates, the ultrasonic crack detector 13 will perform a comprehensive inspection of the pipe to confirm whether there are cracks on the inner wall of the pipe. Step 5: The laser light curtain emitter 8 emits a laser light curtain that overlaps with the outer wall of the pipe. As the pipe rotates, the outer wall of the pipe can be fully inspected. When a bulge appears on the outer wall of the pipe, the bulge will block the laser light curtain and cause the laser light curtain to bend, thus making the identification of the bulge on the outer wall of the pipe more accurate. Step 6: Release the gas through the injection assembly, then connect it to the water pump, inject clean water into the pipe, and monitor the air pressure inside the pipe through the pressure sensor 24 until the air pressure inside the pipe reaches 1.5 times the design pressure that the pipe can withstand. Then close the injection assembly and disconnect it from the external water pump. Then repeat the steps 3, 4 and 5 above to test the water pressure.

[0018] Example 2: The technical solutions in this example that differ from Example 1 include: The drive assembly includes a mounting slot 15, which is located on the upper surface of the mounting base 1. A dual-head drive motor 16 is fixedly installed in the mounting slot 15. Both ends of the dual-head drive motor 16 are fixedly mounted with drive rods 17 via couplings. Drive wheels 18 are fixedly mounted on the drive rods 17. The two drive wheels 18 abut against the corresponding rotating rods 3. When the dual-head drive motor 16 is started, it drives the drive rods 17 to rotate, which in turn drives the drive wheels 18 to rotate. The drive wheels 18, in turn, drive the rotating rods 3 to rotate.

[0019] The upper surface of the mounting base 1 has two grooves, and the lower end of the drive wheel 18 is inserted into the grooves to avoid affecting the rotation of the drive wheel 18.

[0020] The rotating rod 3 has a limiting hole 19, and a limiting rod 20 is slidably connected inside the limiting hole 19. Both ends of the limiting rod 20 extend outside the rotating rod 3, and one end of the limiting rod 20 is fixedly connected to the first clamping seat 6. The limiting hole 19 limits the limiting rod 20, and the limiting rod 20 supports the first clamping seat 6, so that when the threaded rod 5 drives the first clamping seat 6 to move, the first clamping seat 6 can only move in parallel. When the rotating rod 3 rotates, it can cooperate with the limiting rod 20 through the limiting hole 19, so that the rotating rod 3 drives the first clamping seat 6 to rotate.

[0021] The injection assembly includes a threaded groove 25, which is formed on the outer wall of the rotating rod 3. A connecting hole 26 is formed through the threaded groove 25. One end of the connecting hole 26 is set to pass through the second clamping seat 23. An electromagnetic valve 27 is fixedly installed on the inner wall of the connecting hole 26. It can be connected to the output end of an external air compressor and water pump through the threaded groove 25. Gas or clean water is injected into the pipe through the connecting hole 26. When the pressure of the injected gas or clean water reaches the standard, the electromagnetic valve 27 is closed, and then the connection with the output end of the external air compressor and water pump is disconnected.

[0022] The threaded rod 5 extends beyond the first clamping seat 6 to the outside of the rotating rod 3, and a handle 21 is fixedly connected to the end of the threaded rod 5 away from the first clamping seat 6. The threaded rod 5 is rotated by the handle 21, making the rotation of the threaded rod 5 more convenient and efficient.

[0023] Among them, the end of the rectangular rod 11 away from the second fixed seat 12 is fixedly connected to the limiting plate 22. The limiting plate 22 supports the rectangular rod 11, so that the rectangular rod 11 cannot be removed from the rectangular hole 10.
