Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel pipe detection, and specifically to a compressive stainless steel pipe and its strength detection device. Background Technique

[0002] Stainless steel pipes are hollow long round steel materials, mainly widely used in industrial pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments, etc., as well as mechanical structure components. They are also widely used in manufacturing mechanical parts and engineering structures.

[0003] The prior art discloses a Chinese patent with the application number CN202221845710.0, a compressive strength detection device for stainless steel pipe processing, and discloses that through the connection of a ball screw pair, multiple moving plates can drive multiple clamping plates to move in opposite directions. Multiple moving plates are inside multiple limiting grooves and are in sliding contact with two connecting plates, improving the stability of the movement of multiple moving plates. The two ends of the steel pipe can be clamped and fixed by multiple clamping plates, solving the problem of being able to fix steel pipes of various sizes.

[0004] When the above device detects the strength of a stainless steel pipe, it can clamp both ends of the steel pipe. However, the steel pipe is prone to sliding after being subjected to external forces. Therefore, single fixation cannot ensure the stability of the steel pipe during detection. And when detecting the steel pipe, it can only detect a single part of the steel pipe locally and cannot meet the comprehensive detection of the steel pipe. Summary of the Invention

[0005] The purpose of the present invention is to provide a compressive stainless steel pipe and its strength detection device to solve the problems raised in the above background technique.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A compressive stainless steel pipe strength detection device includes a base. In the middle of the upper end surface of the base, two symmetrically arranged vertical plates are installed. A corrugated groove is opened in the middle of the vertical plate. A round rod is slidably installed in the corrugated groove. A center plate is fixedly installed between the two round rods. A rectangular plate is fixedly installed at one end of the round rod away from the center plate. A plurality of springs are commonly installed between the lower end surface of the rectangular plate and the base. Rectangular grooves are symmetrically opened on both sides of the center plate. A T-shaped plate is slidably installed in the rectangular groove. Electric push plates are fixedly installed on both sides of the upper end surface of the T-shaped plate. A disc is fixedly installed on top of the two electric push plates. Rotating frames are slidably installed on one side close to each other of the two discs. An inner cylinder is fixedly installed in the middle of the rotating frame. A detection component is fixedly installed on one side of the center plate. A blanking component is provided on the side of the center plate away from the detection component.

[0008] Further, an adjusting rod is rotationally installed with threads on one side of the upper end surface of the vertical plate. The adjusting rod has threads on its outer surface. A baffle is rotationally installed on the lower end surface of the adjusting rod. The baffle is of a U-shaped structure and is slidably connected to the vertical plate. In the middle of the lower end surface of the central plate, a regulating wheel is rotationally installed through a motor. On both sides of the regulating wheel, there are racks that are engaged and slidably connected to the central plate. On the far sides of the two racks, they are respectively fixedly connected to the corresponding T-shaped plates.

[0009] On the side of the rotating frame away from the disc, a rotating ring is rotationally installed through an electric slider. Inside the rotating ring, multiple circumferentially arranged push-pull plates are rotationally installed. On the side of the push-pull plate away from the rotating ring, an L-shaped frame is rotationally installed. The L-shaped frame is slidably connected to the rotating frame. On the far sides of the multiple L-shaped frames, a limiting plate is slidably installed through an electric slider.

[0010] Further, through grooves are circumferentially opened on the outer side of the inner cylinder. Multiple circumferentially arranged springs are fixedly installed in the inner cavity of the inner cylinder. On the side of the spring away from the inner cylinder, a moving frame is fixedly installed. The moving frame is of a T-shaped setting. On one side of the moving frame, a supporting block that slides in the through groove is fixedly installed. On the other side of the moving frame, an inclined panel is fixedly installed. On both sides of the two inner cylinders away from each other, threaded rods are rotationally installed with threads, and the threaded rods are placed between the disc and the rotating frame. At one end of the threaded rod, a conical block located in the inner cavity of the inner cylinder is fixedly installed.

[0011] Further, a support plate is fixedly installed on one side of the disc. A telescopic plate is jointly installed on the two support plates. In the middle of one side of the telescopic plate, a double-headed push rod is rotationally installed through an electric slider. At both ends of the double-headed push rod, driving pulleys are fixedly installed. On the outer edge of the rotating frame, a driven pulley is fixedly installed. A belt is jointly installed between the driven pulley and the driving pulley.

[0012] Further, the detection component includes a support frame. On one side of the upper end surface of the support frame, two symmetrically arranged rear frames are fixedly installed. A turning plate is jointly rotationally installed between the two rear frames. There is a moving groove opened on the support frame between the two rear frames. A moving block is slidably installed in the moving groove through an electric slider. A through port is opened on the side of the turning plate close to the moving block.

[0013] Further, an inner rod that slides in the through port is provided in the middle of the moving block. On the side of the upper end surface of the support frame away from the rear frame, two symmetrically arranged front frames are fixedly installed. A sliding rod is slidably installed in the middle of the front frame. At the bottom ends of the two sliding rods, a knocking frame is jointly fixedly installed. A central wheel is jointly fixedly installed between the two front frames. A steel wire rope is jointly installed between the knocking frame and the turning plate, and the steel wire rope is wound around the central wheel.

[0014] Further, lifting grooves are equally spaced in the middle of the knocking frame. A knocking rod is slidably installed in the middle of the lifting groove. After the knocking frame knocks on the stainless steel pipe, by observing the height difference between the multiple knocking rods, it is possible to quickly observe whether there are depressions on the surface of the stainless steel pipe.

[0015] Furthermore, the unloading assembly includes two symmetrically arranged movable plates, which are slidably connected to the base through an electric slider, and a supporting plate is installed on the common slider on the upper end surfaces of the two movable plates, and a storage box is fixedly installed on the supporting plate, and a unloading box connected to its inner cavity is fixedly installed on one side of the storage box, and a center rod is installed in the middle of the unloading box through motor rotation, and a shifting frame is fixedly installed on both sides of the center rod, and a unloading plate connected to its inner cavity is fixedly installed on the lower end surface of the unloading box.

[0016] Furthermore, a plurality of circumferentially arranged partition rods are fixedly mounted on the outer wall of the transposition rack. The rotation of the transposition rack drives the plurality of partition rods to be transposed so as to receive the stainless steel pipes in the storage box, and finally roll them onto the center plate through the blanking plate.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention drives two built-in cylinders to be placed in both ends of the stainless steel pipe respectively by bringing two T-shaped plates closer to each other, and knocks the surface of the fixed stainless steel pipe through the detection component. The arrangement of the corrugated groove and the spring can make the stainless steel pipe itself move up and down after being knocked, thereby increasing the contact frequency with the detection component and at the same time increasing the impact force when knocking with the detection component, further strengthening the strength detection of the stainless steel pipe, and driving the stainless steel pipe to rotate by rotating the rotating frame, so that the outer wall of the stainless steel pipe can be circumferentially tested for strength. Compared with the existing device, the fixed steel pipe is rotated in a circumferential manner, thereby achieving a full and comprehensive strength detection of the outer surface of the steel pipe.

[0019] 2. The present invention drives the lifting and lowering of the baffle plate by rotating the adjusting rod, and the lifting and lowering of the baffle plate can be controlled by controlling the lifting and lowering range of the rectangular plate. Finally, after the stainless steel tube is hit, under the action of the spring, the round rod moves up and down in the corrugated groove, thereby driving the stainless steel tube of the center plate to impact up and down, and the elastic force range of the spring can be regulated by adjusting the height of the rectangular plate, thereby realizing the regulation of the impact force of the stainless steel tube itself.

[0020] 3. When the rotating ring rotates, the push-pull plate drives the L-shaped frame to slide on the rotating frame, thereby adjusting the distance between multiple L-shaped frames. Then, the limiting plate on the L-shaped frame corresponds to the outer edge of the stainless steel pipe. Subsequently, the electric slider is activated to drive the limiting plate to move towards the end of the stainless steel pipe, and the limiting plate abuts against the end of the stainless steel pipe, thus achieving the fixation before the strength test of the stainless steel pipe. By rotating the rotating ring and the rotation to drive multiple limiting plates to move, the ends of stainless steel pipes with different diameters can be fixed. By limiting the ends of the stainless steel pipes, the stainless steel pipes can be prevented from sliding left and right during the strength test. Moreover, by the sliding of the limiting plate on the L-shaped frame, the ends of stainless steel pipes with different lengths can be abutted and fixed, meeting the fixation requirements of stainless steel pipes with different specifications during the strength test.

[0021] 4. By rotating the threaded rod, the conical block is driven to move towards the inclined panel. When the conical block moves, it pushes multiple inclined panels outwards. Subsequently, the inclined panels drive the support blocks to move out of the through groove through the moving frame. Finally, multiple support blocks move away from each other to abut against the inner wall of the stainless steel pipe, thus completing the internal support of the stainless steel pipe. Compared with the existing devices, the present invention can, when meeting the strength tests of stainless steel pipes with different pipe diameters and different lengths, also effectively avoid the occurrence of sliding of the stainless steel pipe during the strength test through the internal support and external restriction of the stainless steel pipe to be tested.

[0022] 5. When the electric slider is activated, it drives the moving block to slide towards the rear frame on the support frame. When the moving block slides, it drives the flipping plate to flip. When the flipping plate flips, it drives the knocking frame to slide down through the steel rope. When the knocking frame moves down, it knocks on the outer wall of the stainless steel pipe, thus achieving the strength detection of the stainless steel pipe. By observing the height difference between multiple knocking rods, it is possible to quickly observe whether there are depressions on the surface of the stainless steel pipe and simultaneously quickly know the position of the depressions, and finally detect whether the stainless steel pipe meets the standards.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0037] A compressive strength detection device for stainless steel pipes is a detection device with a workpiece clamping function. The workpiece to be detected in this invention is a stainless steel pipe. After clamping and fixing the stainless steel pipe in this invention, the strength of the stainless steel pipe is detected by knocking on the outside of the stainless steel pipe.

[0038] As Figures 1 - 10 shown, it includes a base 1. In the middle of the upper end surface of the base 1, two symmetrically arranged vertical plates 10 are installed. A corrugated groove 11 is opened in the middle of the vertical plate 10. A round rod is slidably installed in the corrugated groove 11. A central plate 2 is fixedly installed between the two round rods. A rectangular plate 12 is fixedly installed at one end of the round rod away from the central plate 2. A plurality of springs are commonly installed between the lower end surface of the rectangular plate 12 and the base 1. Rectangular grooves are symmetrically opened on both sides of the central plate 2. T-shaped plates 23 are slidably installed in the rectangular grooves. Electric push plates 24 are fixedly installed on both sides of the upper end surface of the T-shaped plates 23. A disc 25 is fixedly installed on the top of the two electric push plates 24. Rotating frames 26 are slidably installed on one side of the two discs 25 close to each other. An inner cylinder 27 is fixedly installed in the middle of the rotating frame 26. A detection component is fixedly installed on one side of the central plate 2. A blanking component is provided on the side of the central plate 2 away from the detection component.

[0039] By moving the two T-shaped plates 23 closer to each other, the two inner cylinders 27 are respectively inserted into both ends of the stainless steel pipe. The detection component knocks on the surface of the fixed stainless steel pipe. Through the settings of the corrugated groove 11 and the springs, when the surface of the stainless steel pipe is knocked, the stainless steel pipe itself can move up and down, thereby increasing the contact frequency with the detection component. At the same time, it can also strengthen the impact force when knocking with the detection component, further strengthening the strength detection of the stainless steel pipe. By rotating the rotating frame 26 to rotate the stainless steel pipe, the circumferential strength detection of the outer wall of the stainless steel pipe can be carried out. Compared with the existing device, in this invention, by rotating the fixed steel pipe in a circular manner, a full and comprehensive strength detection of the outside of the steel pipe can be achieved.

[0040] One side of the upper end surface of the vertical plate 10 is rotatably installed with a threaded adjusting rod 13. The outside of the adjusting rod 13 has threads. A baffle 14 is rotatably installed on the lower end surface of the adjusting rod 13. The baffle 14 is of a U-shaped structure and is slidably connected to the vertical plate 10. A regulating wheel 21 is rotatably installed in the middle of the lower end surface of the central plate 2 through a motor. Two racks 22 meshing with both sides of the regulating wheel 21 are slidably connected to the central plate 2. The two racks 22 are respectively fixedly connected to the corresponding T-shaped plates 23 on the side away from each other.

[0041] By rotating the adjusting rod 13 to drive the lifting of the baffle plate 14, the lifting range of the rectangular plate 12 can be controlled through the lifting of the baffle plate 14. Finally, after the stainless steel pipe is struck, under the action of the spring, the round rod moves up and down in the corrugated groove 11 to drive the stainless steel pipe of the central plate 2 to impact up and down. And by adjusting the height of the rectangular plate 12, the elastic force range of the spring can be regulated, so as to realize the regulation of the impact force of the stainless steel pipe itself.

[0042] On one side of the rotating frame 26 away from the disc 25, a rotating ring 261 is rotatably installed through an electric slider. Inside the rotating ring 261, a plurality of circumferentially arranged push-pull plates 262 are rotatably installed. On one side of the push-pull plate 262 away from the rotating ring 261, an L-shaped frame 263 is rotatably installed. The L-shaped frame 263 is slidably connected to the rotating frame 26. On the side where the plurality of L-shaped frames 263 are away from each other, a limiting plate 264 is slidably installed through an electric slider.

[0043] By starting the electric slider to drive the rotating ring 261 to rotate, when the rotating ring 261 rotates, it drives the L-shaped frame 263 to slide on the rotating frame 26 through the push-pull plate 262, so as to adjust the distance between the plurality of L-shaped frames 263, and then make the limiting plate 264 on the L-shaped frame 263 correspond to the outer edge of the stainless steel pipe. Subsequently, the electric slider is started to drive the limiting plate 264 to move towards the end of the stainless steel pipe, and the limiting plate 264 abuts against the end of the stainless steel pipe, so as to realize the fixation before the strength test of the stainless steel pipe. By rotating the rotating ring 261 and rotating to drive the plurality of limiting plates 264 to move, the ends of stainless steel pipes with different diameters can be fixed. By limiting the ends of the stainless steel pipes, the stainless steel pipes are prevented from sliding left and right during the strength test. And by the limiting plate 264 sliding on the L-shaped frame 263, the ends of stainless steel pipes with different lengths can be abutted and fixed, meeting the fixation requirements of stainless steel pipes with different specifications during the strength test.

[0044] On the outer side of the built-in cylinder 27, a through groove 271 is circumferentially opened. Inside the built-in cylinder 27, a plurality of circumferentially arranged springs are fixedly installed. On one side of the spring away from the built-in cylinder 27, a moving frame 272 is fixedly installed. The moving frame 272 is arranged in a T shape. On one side of the moving frame 272, a support block 274 that slides in the through groove 271 is fixedly installed. On the other side of the moving frame 272, an inclined panel 273 is fixedly installed. On both sides where the two built-in cylinders 27 are away from each other, a threaded rod 275 is rotatably installed by threading, and the threaded rod 275 is placed between the disc 25 and the rotating frame 26. One end of the threaded rod 275 is fixedly installed with a conical block 276 located inside the built-in cylinder 27.

[0045] After placing the built-in cylinder 27 inside the stainless steel pipe, rotate the threaded rod 275 to drive the tapered block 276 to move towards the inclined panel 273. When the tapered block 276 moves, it pushes out multiple inclined panels 273. Subsequently, the inclined panels 273 drive the support blocks 274 to move out of the through slots 271 through the moving frames 272. Finally, multiple support blocks 274 move away from each other and abut against the inner wall of the stainless steel pipe, thus completing the support inside the stainless steel pipe. Compared with the existing devices, the present invention can, when satisfying the strength tests of stainless steel pipes with different pipe diameters and lengths, also effectively avoid the occurrence of sliding of the stainless steel pipe during the strength test through the internal support and external restriction of the stainless steel pipe to be tested.

[0046] One side of the disc 25 is fixedly installed with a support plate 31. The two support plates 31 on both sides are jointly installed with a telescopic plate 32. The middle part of one side of the telescopic plate is rotatably installed with a two-way push rod 33 through an electric slider. Both ends of the two-way push rod 33 are fixedly installed with driving pulleys 34. The outer edge of the rotating frame 26 is fixedly installed with a driven pulley 35. A belt 36 is jointly installed between the driven pulley 35 and the driving pulley 34.

[0047] The detection component includes a support frame 41. One side of the upper end surface of the support frame 41 is fixedly installed with two symmetrically arranged rear frames 42. A turning plate 43 is jointly rotatably installed between the two rear frames 42. There is a moving groove opened on the support frame 41 between the two rear frames 42. A moving block 44 is slidably installed in the moving groove through an electric slider. A through hole is opened on the side of the turning plate 43 close to the moving block 44.

[0048] The middle part of the moving block 44 is provided with an inner rod that slides in the through hole. One side of the upper end surface of the support frame 41 far from the rear frame 42 is fixedly installed with two symmetrically arranged front frames 45. A sliding rod 46 is slidably installed in the middle of the front frame 45. The bottom ends of the two sliding rods 46 are jointly fixedly installed with a knocking frame 48. A central wheel 47 is jointly fixedly installed between the two front frames 45. A steel rope is jointly installed between the knocking frame 48 and the turning plate 43, and the steel rope is wound around the central wheel 47.

[0049] When performing a strength test on the fixed stainless steel pipe, the electric slider is turned on to drive the moving block 44 to slide on the support frame 41 towards the rear frame 42. When the moving block 44 slides, it drives the turning plate 43 to turn. When the turning plate 43 turns, it drives the knocking frame 48 to slide down through the steel rope. When the knocking frame 48 moves down, it knocks on the outer wall of the stainless steel pipe, thereby realizing the strength test of the stainless steel pipe.

[0050] Lifting grooves 481 are equally spaced in the middle of the knocking frame 48. A knocking rod 482 is slidably installed in the middle of the lifting grooves 481. After the knocking frame 48 knocks on the stainless steel pipe, the height difference between multiple knocking rods 482 can be observed to quickly observe whether there are depressions on the surface of the stainless steel pipe.

[0051] The unloading assembly includes two symmetrically arranged movable plates 51, which are slidably connected to the base 1 through an electric slider. The upper end surfaces of the two movable plates 51 are commonly mounted with a supporting plate 52, and a storage box 53 is fixedly mounted on the supporting plate 52. A unloading box 54 connected to an inner cavity of the storage box 53 is fixedly mounted on one side of the storage box 53. A center rod 55 is mounted in the middle of the unloading box 54 through motor rotation, and a shifting frame 56 is fixedly mounted on both sides of the center rod 55. A unloading plate 57 connected to an inner cavity of the unloading box 54 is fixedly mounted on the lower end surface.

[0052] When the stainless steel pipe to be inspected is unloaded, the motor is turned on to drive the central rod 55 to rotate. When the central rod 55 rotates, the position change frame 56 is driven to rotate synchronously to realize the unloading of the stainless steel pipe.

[0053] A plurality of circumferentially arranged partition rods are fixedly mounted on the outer wall of the transposition rack 56 . The rotation of the transposition rack 56 drives the plurality of partition rods to transpose so as to receive the stainless steel pipes in the storage box 53 , and finally rolls onto the center plate 2 through the blanking plate 57 .

[0054] When the present invention is in use, the stainless steel tube is placed on the center plate 2, and then the motor is turned on to drive the regulating wheel 21 to rotate. When the regulating wheel 21 rotates, it drives the two racks 22 to approach each other, so that the two T-shaped plates 23 are close to each other and drive the two built-in cylinders 27 to be respectively placed in the two ends of the stainless steel tube. The electric slider is turned on to drive the rotating ring 261 to rotate. When the rotating ring 261 rotates, it drives the L-shaped frame 263 to slide on the rotating frame 26 through the push-pull plate 262, so that the spacing between the multiple L-shaped frames 263 is adjusted, and then the limit plate 264 on the L-shaped frame 263 corresponds to the outer edge of the stainless steel tube, and then the electric slider is turned on. The limiting plate 264 is driven to move toward the end of the stainless steel pipe, and the limiting plate 264 abuts against the end of the stainless steel pipe, thereby fixing the stainless steel pipe before the strength test. The multiple limiting plates 264 are driven to move by the swivel 261 and the rotation, and the ends of stainless steel pipes of different diameters can be fixed. By limiting the ends of the stainless steel pipe, the stainless steel pipe is prevented from sliding left and right during the strength test. In addition, the limiting plate 264 slides on the L-shaped frame 263, and the ends of stainless steel pipes of different lengths can be abutted and fixed, meeting the fixation requirements of stainless steel pipes of different specifications during the strength test.

[0055] Rotate the threaded rod 275 to drive the tapered block 276 to move towards the inclined panel 273. When the tapered block 276 moves, it pushes out multiple inclined panels 273. Subsequently, the inclined panel 273 drives the support block 274 to move out of the through groove 271 through the moving frame 272. Finally, multiple support blocks 274 move away from each other and abut against the inner wall of the stainless steel pipe, thus completing the internal support of the stainless steel pipe. Compared with the existing devices, the present invention can, when meeting the strength tests of stainless steel pipes with different diameters and lengths, also effectively avoid the occurrence of sliding of the stainless steel pipe during the strength test through the internal support and external restriction of the stainless steel pipe to be tested;

[0056] When performing a strength test on the fixed stainless steel pipe, the electric slider is turned on to drive the moving block 44 to slide towards the rear frame 42 on the support frame 41. When the moving block 44 slides, it drives the flip plate 43 to flip. When the flip plate 43 flips, it drives the percussion frame 48 to slide down through the steel rope. When the percussion frame 48 moves down, it strikes the outer wall of the stainless steel pipe, thus realizing the strength test of the stainless steel pipe. By rotating the adjusting rod 13, the lifting and lowering of the abutting baffle 14 can be driven. Through the lifting and lowering of the abutting baffle 14, the lifting range of the rectangular plate 12 can be controlled. Finally, after the stainless steel pipe is struck, under the action of the spring, the round rod moves up and down in the corrugated groove 11 to drive the stainless steel pipe of the central plate 2 to perform up and down impacts, and the elastic force range of the spring can be adjusted through the height adjustment of the rectangular plate 12, thereby realizing the adjustment of the impact force on the stainless steel pipe itself.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
