DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0021] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0022] An alloy wire corrosion resistance testing device provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings. Embodiment 1:

[0023] Combination Figure 1-Figure 9 As shown, an alloy wire corrosion resistance testing device provided by the present invention includes a lead assembly 100, a liquid injection testing mechanism 200 installed on the lead assembly 100, a tubular cavity pressurizing mechanism 300 installed in the liquid injection testing mechanism 200, and two sets of wire end tightening mechanisms 400 installed on the liquid injection testing mechanism 200.

[0024] The lead wire assembly 100 includes a bracket 110, an inlet pipe 120, a support leg 130 and an alloy wire 140. The liquid injection test mechanism 200 includes a transparent test tube 210, a drainage assembly 220, a liquid inlet assembly 230, a sealing cover 240, a support plate 250, a locking bolt 260, a partition 270 and a calibration column 280. The lumen pressurization mechanism 300 includes a clamp seat 310, a positioning bolt 320, a traction rod 330, a traction frame 340, a chuck 350, a pressure-resistant sleeve 360 ​​and a pressurization disk 370. The wire head tightening mechanism 400 includes an anti-seepage disk 410, an anti-seepage sleeve 420, a reinforcement sleeve 430, a sliding cover 440, a pressurization pad 450 and a pre-tightening bolt 460.

[0025] The lead assembly 100 includes a stretched alloy wire 140; The liquid injection test mechanism 200 includes a transparent test tube 210 disposed outside the alloy wire 140, a liquid inlet assembly 230 mounted on the transparent test tube 210, a liquid discharge assembly 220 mounted on the transparent test tube 210, four sealing covers 240 mounted on the transparent test tube 210, and a calibration column 280 movably mounted in the sealing cover 240; The lumen pressurizing mechanism 300 includes two pressurizing disks 370 disposed in the inner cavity of the transparent test tube 210 and a pressure-resistant sleeve 360 ​​fixedly installed in the pressurizing disks 370; The thread tightening mechanism 400 includes an impermeable disk 410 installed at the outer end of the transparent test tube 210 and an impermeable sleeve 420 installed in the impermeable disk 410 .

[0026] During the period of use, the alloy wire is easily disturbed by various factors in the assembly environment. In particular, after the alloy wire is subjected to external force and immersed in the solution, the wire is more likely to be corroded and broken. The existing testing equipment mainly places the cut samples in a reagent dish for reaction and observes the corrosion state of the samples within a rated time period. However, this method cannot simulate the corrosion environment of the alloy wire after actual assembly, and is not conducive to comparative testing of the alloy wire under pressure and hydraulic pressure in different solutions.

[0027] When the alloy wire 140 extends from the two reinforcing sleeves 430 and the two anti-seepage sleeves 420, the part of the alloy wire 140 to be tested will be immersed in the inner cavity of the transparent test tube 210. At this time, the two pressure-resistant sleeves 360 and the two pressure-boosting disks 370 arranged in the inner cavity of the transparent test tube 210 can further reduce the part of the alloy wire 140 to be tested, and provide a relatively sealed test space for the part of the alloy wire 140 to be tested. After the liquid inlet component 230 transfers the solution to be tested to the transparent test tube 210 and the cavity between the two pressure-boosting disks 370, a test time period is set, and a gradual pressure is applied to the part of the alloy wire 140 to be tested during this time period. At this time, the corrosion speed of the alloy wire 140 under external pressure is simulated, and at the same time, by changing the hydraulic pressure of the solution to be tested, the gradually pressurized part of the alloy wire 140 can be compared in the continuously pressurized solution to be tested. Embodiment 2:

[0028] Combination Figure 2-Figure 8 As shown, based on the first embodiment, the lead assembly 100 further includes a bracket 110, a wire inlet tube 120 fixedly installed in the bracket 110, and two legs 130 installed on the bracket 110; The alloy wire 140 penetrates into the inlet pipe 120; The liquid injection test mechanism 200 further includes a support plate 250, the support plate 250 is fixedly mounted on the top of the sealing cover 240, a locking bolt 260 movably mounted in the support plate 250, and a partition plate 270 movably mounted on the locking bolt 260; A hole is formed at one end of the partition plate 270 away from the locking bolt 260, and a bolt is disposed in the hole, and the bolt is connected to the calibration column 280; The transparent test tube 210 is made of transparent glass, and both ends of the transparent test tube 210 are provided with annular grooves adapted to be clamped to the anti-seepage disk 410; The transparent test tube 210 is fixedly mounted on the two legs 130; The liquid inlet assembly 230 and the liquid discharge assembly 220 are both composed of end pipes, ball valves and hoses.

[0029] The cavity between the two pressurizing disks 370 is observed through the transparent test tube 210. As the liquid inlet component 230 injects the test solution, the alloy wire 140 limited by the two pressure-resistant sleeves 360 can be partially immersed in the test solution. When the locking bolt 260 is controlled to rotate clockwise, the pressurized partition 270 will apply a thrust to the calibration column 280. At this time, the two adjacent calibration columns 280 can clamp the part of the alloy wire 140 that passes through the outside of the pressure-resistant sleeve 360. As the two adjacent calibration columns 280 are progressively pressurized, the alloy wire 140 can be continuously pressurized in the test solution, thereby simulating the real-time state of the alloy wire 140 being pressurized and corroded by the solution in an actual environment. Embodiment three:

[0030] Combination Figure 2-Figure 8 As shown, on the basis of the first embodiment, the lumen pressurizing mechanism 300 further includes a clamping seat 310 fixedly mounted on the transparent test tube 210, a positioning bolt 320 connected to the clamping seat 310, a traction rod 330 movably mounted in the clamping seat 310, two traction frames 340 movably connected to the traction rod 330, and a clamp 350 movably connected to the bottom end of the traction frame 340; The chuck 350 is fixedly mounted on the pressure-resistant sleeve 360 ​​.

[0031] The outer wall of the traction rod 330 is provided with a scale, and the traction rod 330 is used to provide traction kinetic energy for the opening and closing of the two traction frames 340 .

[0032] The clamp seat 310 is fixedly installed on the transparent test tube 210, and the traction mark rod 330 is movably installed in the clamp seat 310. At this time, the bottom end of the traction mark rod 330 will penetrate into the inner cavity of the transparent test tube 210. When the two traction frames 340 are movably connected to the bottom end of the traction mark rod 330, and the bottom end of the traction frame 340 is connected to the clamp 350, by loosening the positioning bolts 320 and controlling the traction mark rod 330 to drive the two traction frames 340 to lift upward, the two pressure-resistant sleeves 360 and the two boosting disks 370 can continuously pressurize the solution to be tested. At this time, the local part of the alloy wire 140 can be subjected to corrosion testing by the continuously pressurized solution under a gradually compressed state. Embodiment 4:

[0033] Combination Figure 2-Figure 9 As shown, based on the first embodiment, the wire tightening mechanism 400 also includes a reinforcement sleeve 430, which is installed on multiple studs of the anti-seepage disk 410 through multiple nuts, two sliding covers 440 installed in the reinforcement sleeve 430, a pre-tightening bolt 460 threadedly installed in the sliding cover 440, and a booster pad 450 movably installed on the pre-tightening bolt 460.

[0034] An anti-seepage ring groove is provided on one side of the anti-seepage disk 410 close to the transparent test tube 210; The anti-seepage sleeve 420 is made of rubber material, and one end of the anti-seepage sleeve 420 is adapted to be clamped in the groove at the inner end of the reinforcement sleeve 430 .

[0035] A slideway adapted to the boost pad 450 is provided on the inner side of the slide cover 440 , and a U-shaped slot is provided at one end of the boost pad 450 . The pre-tightening bolt 460 penetrates through the column head inside the slide cover 440 and is adapted and snapped into the U-shaped slot.

[0036] By installing two anti-seepage disks 410 at both ends of the transparent test tube 210 and installing an anti-seepage sleeve 420 in the middle of the anti-seepage disks 410, when the alloy wire 140 passes through the two wire inlet pipes 120 and is pressed and fixed by two sets of pressure pads 450, the part of the alloy wire 140 that passes through the inner cavity of the transparent test tube 210 can be in a safe test environment. At this time, the alloy wire 140 in the initial state can be parallel to the center line of the inner cavity of the transparent test tube 210. At this time, the device can provide a platform for safe comparative experiments for the alloy wire 140.

[0037] The working principle and use process of the present invention are as follows: the chuck 350 is fixedly installed on the pressure-resistant sleeve 360 ​​in advance, and the pressure-resistant sleeve 360 ​​is fixedly installed in the middle of the booster disk 370, and the bottom end of the traction frame 340 is movably installed on the chuck 350, and at the same time, the top ends of the other two adjacent traction frames 340 are movably installed on the end of the traction mark rod 330 that penetrates into the inner cavity of the transparent test tube 210, and the top end of the traction mark rod 330 penetrates to the outside of the clamp seat 310, and the positioning bolt 320 threadedly installed in the clamp seat 310 is used to lock and fix the traction mark rod 330 after lifting. At this time, the two booster disks 370 will be located in the middle of the inner cavity of the transparent test tube 210, and then the four sealing covers 240 are respectively installed in the four notches of the transparent test tube 210, and the four calibration columns 2 are sequentially installed. The diaphragm 270 is movably mounted inside the four sealing covers 240, and the outer end of the sealing cover 240 is fixed to the partition 270 by bolts, and the other end of the partition 270 is movably mounted on the middle part of the locking bolt 260. As the locking bolt 260 rotates clockwise, the locking bolt 260 will fall down along the screw hole on the top of the support plate 250, and the partition 270 pushed downward will also synchronously pull the calibration column 280 to extend toward the inner cavity of the transparent test tube 210 until the ends of the two adjacent calibration columns 280 clamp and fix the alloy wire 140 along the center line of the inner cavity of the transparent test tube 210. At the same time, according to the pressure requirements of the alloy wire 140 passing through the two ends of the inner cavity of the transparent test tube 210, the lifting height of the two parts of the alloy wire 140 clamped by the two sets of calibration columns 280 can be gradually adjusted; When in use, the alloy wire 140 is inserted into the holes of the reinforcing sleeve 430, the anti-seepage sleeve 420 and the anti-seepage disk 410 in advance, until the alloy wire 140 passes through the two pressure-resistant sleeves 360 in sequence along the inner cavity of the transparent test tube 210, and is finally clamped by the two sets of calibration columns 280. During the initial test, the two sets of calibration columns 280 are needed to horizontally clamp and fix the alloy wire 140 along the center line of the transparent test tube 210, then open the valve in the liquid inlet component 230, and the valve in the tube wall sealing cover 240, and then transfer the solution to be tested from the liquid inlet component 230 to the transparent test tube 210 and the cavity between the two booster disks 370, then set the test time, and change the height of the two sets of calibration columns 280. At this time, the alloy wire 140 is subjected to the two anti- The compression sleeve 360 ​​will be subjected to gradual pressure by the two sets of calibration columns 280 under the load. In this state, the alloy wire 140 can detect the interference of external pressure on its own corrosion in the rated test solution, and then loosen the positioning bolt 320, and control the traction mark 330 to lift upward. At this time, the two booster disks 370 will shrink. At this time, the pressure of the solution in the inner cavity of the transparent test tube 210 will increase. This process can compare the corrosion caused by the increase in solution pressure when the alloy wire 140 itself is under pressure. Similarly, multiple sets of this device can be added to the body of the longer alloy wire 140. By adding different test solutions and changing the pressure factor, the corrosion changes of the alloy wire 140 under different solutions or pressures during actual use can be simulated.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
