This utility model provides a metal tube tensile testing device that improves overall work efficiency and saves manpower and time costs. However, when using this device, a metal tube needs to be placed onto the tensile assembly, stretched, and then removed. It cannot continuously stretch multiple metal tubes, resulting in relatively low processing efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a fatigue-resistant metal tube tensile testing device, which can solve the technical problem that when the device is used, a metal tube needs to be placed on the tensile component and then stretched, and then removed. It cannot continuously stretch multiple metal tubes, resulting in relatively low processing efficiency.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a fatigue-resistant metal tube tensile testing device, including a workbench, a cover fixedly connected to the upper end of the workbench, a rotating shaft provided at the bottom of the inside of the cover, a support rod fixedly connected to the upper end of the rotating shaft, a driven gear fixedly connected to the outer side of the support rod, and the driven gear cooperating with a drive assembly, a disc fixedly connected to the upper end of the support rod, four placement boxes provided at the upper end of the disc, a fixing ring fixedly connected to the inner wall of the placement box, a pair of fixing plates fixedly connected to the upper end of the placement box, a first hydraulic rod provided on the fixing plate, a first clamping plate fixedly connected to the output end of the first hydraulic rod, an anti-slip pad provided on one side of the first clamping plate, and a tensile assembly provided at the upper end of the workbench.

[0006] As a preferred technical solution of this utility model, the driving component is as follows: a first motor is provided at the lower end of the worktable, the output end of the first motor passes through the worktable and the cover and is fixedly connected to the driving gear, and the driving gear meshes with the driven gear.

[0007] As a preferred embodiment of this utility model, the stretching assembly is as follows: a bracket is fixedly connected to the upper end of the worktable, a second motor is provided at the upper end of the bracket, the output end of the second motor passes through the bracket and is fixedly connected to a threaded rod, and a threaded sleeve is threadedly connected to the threaded rod, a limit plate is fixedly connected to one side of the threaded sleeve, and one end of the limit plate is inserted into a limit groove on the bracket, a baffle is fixedly connected to one side of the threaded sleeve, a U-shaped frame is fixedly connected to one side of the baffle, a pair of second hydraulic rods are provided on the U-shaped frame, and a second clamping plate is fixedly connected to the output end of the second hydraulic rods.

[0009] As a preferred embodiment of this utility model, a controller is provided at the upper end of the battery.

[0010] As a preferred embodiment of this utility model, a switch door is provided on one side of the cover.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: By inserting anti-fatigue metal tubes into multiple placement boxes, and with the help of fixing rings, the anti-fatigue metal tubes are effectively fixed. Simultaneously, multiple first hydraulic rods are activated, causing the first clamping plates to move. The anti-slip pads on the first clamping plates effectively clamp and fix the anti-fatigue metal tubes. At the same time, a second motor is activated, driving a threaded rod to rotate. This rotation of the threaded rod moves a threaded sleeve, which moves more stably under the limiting action of the limiting plate and limiting groove, until the anti-fatigue metal tube is positioned between two second clamping plates. Then, a second hydraulic rod is activated, causing the second clamping plates to clamp and fix the anti-fatigue metal tube. Simultaneously, the second motor is activated, driving the threaded rod to rotate. This rotation of the threaded rod moves the threaded sleeve, which in turn indirectly moves the U-shaped frame and the second... The clamping plates move upwards, effectively enabling tensile testing of fatigue-resistant metal tubes. When another fatigue-resistant metal tube needs to be tested, the second hydraulic rod is activated, causing it to move the second clamping plate away from clamping the fatigue-resistant metal tube. The second motor is then activated, indirectly moving the second clamping plate upwards a short distance. Simultaneously, the first motor is activated, driving the drive gear. Under the action of the rotating shaft, the drive gear drives the driven gear, indirectly rotating the disc and the fatigue-resistant metal tube until the other fatigue-resistant metal tube is below the two second clamping plates. This process is repeated, allowing for continuous tensile testing of multiple fatigue-resistant metal tubes. This device enables continuous tensile testing of multiple metal tubes, improving processing efficiency. Attached Figure Description

A switch door 27 is provided on one side of the cover 2. The fatigue-resistant metal tube can be installed and removed through the switch door 27.

[0015] As a further implementation of this embodiment, such as Figures 1-6 As shown, a cover 2 is fixedly connected to the upper end of the workbench 1. A rotating shaft 3 is provided at the bottom of the inside of the cover 2. A support rod 4 is fixedly connected to the upper end of the rotating shaft 3. A driven gear 5 is fixedly connected to the outer side of the support rod 4, and the driven gear 5 cooperates with the drive assembly. A disc 6 is fixedly connected to the upper end of the support rod 4. Four placement boxes 7 are provided at the upper end of the disc 6. A fixing ring 8 is fixedly connected to the inner wall of the placement box 7. A pair of fixing plates 9 are fixedly connected to the upper end of the placement box 7. A first hydraulic rod 10 is provided on the fixing plate 9. A first clamping plate 11 is fixedly connected to the output end of the first hydraulic rod 10. An anti-slip pad 12 is provided on one side of the first clamping plate 11. A tensioning assembly is provided at the upper end of the workbench 1.

[0016] The drive assembly is as follows: A first motor 13 is installed at the lower end of the worktable 1. The output end of the first motor 13 passes through the worktable 1 and the cover 2 and is fixedly connected to the drive gear 14. The drive gear 14 meshes with the driven gear 5. The tensioning assembly is as follows: A bracket 15 is fixedly connected to the upper end of the worktable 1. A second motor 16 is installed at the upper end of the bracket 15. The output end of the second motor 16 passes through the bracket 15 and is fixedly connected to the threaded rod 17. A threaded sleeve 18 is threadedly connected to the threaded rod 17. A limit switch is fixedly connected to one side of the threaded sleeve 18. Plate 19, and one end of the limiting plate 19 is inserted into the limiting groove 20 on the bracket 15. A baffle 21 is fixedly connected to one side of the threaded sleeve 18, and the baffle 21 can slide in contact with the inner wall of the cover 2. At the same time, the baffle 21 and the cover 2 can seal and shield the fatigue-resistant metal tube to prevent it from being damaged and splashed during stretching, which would cause danger to the workers. A U-shaped frame 22 is fixedly connected to one side of the baffle 21. A pair of second hydraulic rods 23 are provided on the U-shaped frame 22, and the output end of the second hydraulic rods 23 is fixedly connected to a second clamping plate 24.

[0017] In use, the anti-fatigue metal tubes are inserted into multiple placement boxes 7, and are effectively fixed by the fixing rings 8. Simultaneously, multiple first hydraulic rods 10 are activated, causing the first clamping plates 11 to move. The anti-slip pads 12 on the first clamping plates 11 effectively clamp and fix the anti-fatigue metal tubes. At the same time, the second motor 16 is activated, causing the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the threaded sleeve 18 to move. The threaded sleeve 18 moves more stably under the limiting action of the limiting plate 19 and the limiting groove 20 until the anti-fatigue metal tube is located between two second clamping plates 24. Simultaneously, the second hydraulic rod 23 is activated, causing the second clamping plates 24 to clamp and fix the anti-fatigue metal tube. The second motor 16 is also activated, causing the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the threaded sleeve 18 to move, thus... The device indirectly drives the U-shaped frame 22 and the second clamping plate 24 to move upward, thus effectively performing tensile tests on fatigue-resistant metal tubes. When another fatigue-resistant metal tube needs to be tested, the second hydraulic rod 23 is activated, causing it to move the second clamping plate 24 and release it from clamping the fatigue-resistant metal tube. The second motor 16 is then activated, indirectly moving the second clamping plate 24 upward a certain distance. Simultaneously, the first motor 13 is activated, causing the drive gear 14 to rotate. Under the action of the rotating shaft 3, the drive gear 14 can drive the driven gear 5 to rotate, thus indirectly driving the disc 6 and the fatigue-resistant metal tube to rotate until the other fatigue-resistant metal tube is below the two second clamping plates 24. The above operation is repeated, thus enabling continuous tensile tests on multiple fatigue-resistant metal tubes. This device allows for continuous tensile testing of multiple metal tubes, thereby improving processing efficiency.

[0018] Specific working principle: In use, the anti-fatigue metal tubes are inserted into multiple placement boxes 7, and are effectively fixed by the fixing rings 8. Simultaneously, multiple first hydraulic rods 10 are activated, causing the first clamping plates 11 to move. The anti-slip pads 12 on the first clamping plates 11 effectively clamp and fix the anti-fatigue metal tubes. Simultaneously, the second motor 16 is activated, causing the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the threaded sleeve 18 to move. The threaded sleeve 18 moves more stably under the limiting action of the limiting plate 19 and the limiting groove 20 until the anti-fatigue metal tube is located between two second clamping plates 24. At the same time, the second hydraulic rod 23 is activated, causing the second clamping plates 24 to clamp and fix the anti-fatigue metal tube. Simultaneously, the second motor 16 is activated, causing the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the threaded sleeve 18 to move. The movement can indirectly drive the U-shaped frame 22 and the second clamping plate 24 to move upward, thus effectively performing tensile tests on the fatigue-resistant metal tube. When it is necessary to perform a tensile test on another fatigue-resistant metal tube, the second hydraulic rod 23 can be activated to drive the second clamping plate 24 and remove it from clamping the fatigue-resistant metal tube. Then, the second motor 16 can be activated to indirectly drive the second clamping plate 24 to move upward a certain distance. At the same time, the first motor 13 can be activated to drive the drive gear 14 to rotate. Under the action of the rotating shaft 3, the drive gear 14 can drive the driven gear 5 to rotate, thus indirectly driving the disc 6 and the fatigue-resistant metal tube to rotate until the other fatigue-resistant metal tube is below the two second clamping plates 24. The above operation is repeated, thus enabling continuous tensile tests on multiple fatigue-resistant metal tubes. This device can effectively and continuously stretch multiple metal tubes, thereby improving processing efficiency.
