Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pipe detection, in particular to a compression-resistant stainless steel pipe and a strength detection device thereof. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines and mechanical structural parts in petroleum, chemical, medical, food, light industry, mechanical instrumentation, etc. It is also widely used in the manufacture of mechanical parts and engineering structures.

[0003] The prior art discloses a Chinese patent with application number CN202221845710.0, which is a compressive strength detection device for stainless steel pipe processing. It also discloses that a plurality of movable plates can drive a plurality of clamping plates to move in relative directions through a ball nut pair connection. The plurality of movable plates are all inside a plurality of limit grooves and in sliding contact with the two connecting plates, thereby improving the stability of the movement of the plurality of movable plates.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention drives two built-in tubes to be placed in both ends of a stainless steel pipe by bringing two T-shaped plates close to each other, and knocks the surface of the fixed stainless steel pipe through a detection component. The arrangement of the corrugated groove and the spring enables the stainless steel pipe to move up and down after being knocked, thereby increasing the contact frequency with the detection component and strengthening 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.

[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 control 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 adjusted by adjusting the height of the rectangular plate, thereby realizing the regulation of the impact force of the stainless steel tube itself.

[0020] 3. The present invention drives the L-shaped frame to slide on the rotating frame by the push-pull plate when the rotating ring rotates, thereby adjusting the spacing between the multiple L-shaped frames, and then making the limit plate on the L-shaped frame correspond to the outer edge of the stainless steel pipe, and then the electric slider opens to drive the limit plate to move toward the end of the stainless steel pipe, and the limit plate abuts the end of the stainless steel pipe, thereby achieving fixation of the stainless steel pipe before the strength test, and driving the movement of multiple limit plates by the rotating ring and rotation, so that the ends of stainless steel pipes of different diameters can be fixed, and by limiting the ends of the stainless steel pipe, the stainless steel pipe is prevented from sliding left and right during the strength test, and the limit plate slides on the L-shaped frame, so that the ends of stainless steel pipes of different lengths can be abutted and fixed, meeting the fixation of stainless steel pipes of different specifications during the strength test.

[0021] 4. The present invention drives the conical block to move toward the inclined plate by rotating the threaded rod. When the conical block moves, multiple inclined plates are pushed outward. Then the inclined plate drives the support block to move out of the through groove through the moving frame. Finally, multiple support blocks move away from each other and abut against the inner wall of the stainless steel pipe, thereby completing the support for the inside of the stainless steel pipe. Compared with the existing device, the present invention can meet the strength test of stainless steel pipes of different diameters and lengths, and can also effectively avoid the sliding of the stainless steel pipe during the strength test by internal support and external restriction of the stainless steel pipe to be tested.

By observing the height difference between multiple knocking rods, it is possible to quickly observe whether there is a depression on the surface of the stainless steel pipe, and at the same time quickly know the position of the depression, and finally detect whether the stainless steel pipe meets the standards.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] A compression-resistant stainless steel pipe strength detection device is a detection device with a clamping workpiece. The detection workpiece in the invention is a stainless steel pipe. After the stainless steel pipe is clamped and fixed, the strength of the stainless steel pipe is detected by knocking on the outside of the stainless steel pipe.

[0038] like Figure 1-Figure 10 As shown, it includes a base 1, two symmetrically arranged vertical plates 10 are installed in the middle of the upper end surface of the base 1, 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 center plate 2 is fixedly installed between the two round rods, a rectangular plate 12 is fixedly installed at the end of the round rod away from the center plate 2, a plurality of springs are 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 center plate 2, a T-shaped plate 23 is slidably installed in the rectangular groove, electric push plates 24 are fixedly installed on both sides of the upper end surface of the T-shaped plate 23, a disc 25 is fixedly installed on the top of the two electric push plates 24, a rotating frame 26 is slidably installed on the side close to the two discs 25, a built-in cylinder 27 is fixedly installed in the middle of the rotating frame 26, a detection component is fixedly installed on one side of the center plate 2, and a blanking component is provided on the side of the center plate 2 away from the detection component.

[0039] By bringing the two T-plates 23 closer to each other, the two built-in cylinders 27 are respectively placed in the two ends of the stainless steel pipe, and the detection component is used to knock on the surface of the fixed stainless steel pipe. The arrangement of the corrugated groove 11 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 enhancing 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 26, so that the outer wall of the stainless steel pipe can be circumferentially tested for strength. Compared with the existing device, the present invention realizes a comprehensive strength detection of the outer side of the steel pipe by rotating the fixed steel pipe in a circumferential manner.

[0040] An adjusting rod 13 is rotatably installed on one side of the upper end surface of the vertical plate 10, and a thread is provided on the outside of the adjusting rod 13. A stop plate 14 is rotatably installed on the lower end surface of the adjusting rod 13. The stop plate 14 is a U-shaped structure and is slidably connected to the vertical plate 10. A regulating wheel 21 is rotatably installed on the middle part of the lower end surface of the center plate 2 through a motor. Racks 22 slidably connected to the center plate 2 are meshed on both sides of the regulating wheel 21. The two racks 22 are fixedly connected to the corresponding T-shaped plates 23 on the far side.

[0041] By rotating the adjusting rod 13, the support plate 14 is driven to rise and fall, and the lifting and lowering of the support plate 14 can further control the lifting and lowering range of the rectangular plate 12. 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 11, thereby driving the stainless steel tube of the center plate 2 to impact up and down, and the height adjustment of the rectangular plate 12 can adjust the elastic force range of the spring, thereby realizing the regulation of the impact force of the stainless steel tube itself.

[0042] A swivel ring 261 is rotatably installed on the side of the rotating frame 26 away from the disc 25 through an electric slider, and a plurality of circumferentially arranged push-pull plates 262 are rotatably installed on the inner side of the swivel ring 261. An L-shaped frame 263 is rotatably installed on the side of the push-pull plate 262 away from the swivel ring 261. The L-shaped frame 263 is slidably connected to the rotating frame 26, and a limit plate 264 is slidably installed on the side away from the plurality of L-shaped frames 263 through an electric slider.

[0043] The electric slider is opened to drive the rotating ring 261 to rotate. When the rotating ring 261 rotates, the push-pull plate 262 drives the L-shaped frame 263 to slide on the rotating frame 26, so that the spacing between the multiple L-shaped frames 263 is adjusted, and then the limiting plate 264 on the L-shaped frame 263 corresponds to the outer edge of the stainless steel pipe. Then the electric slider is opened to drive the limiting plate 264 to move toward the end of the stainless steel pipe. The limiting plate 264 abuts the end of the stainless steel pipe, thereby achieving the fixation of the stainless steel pipe before the strength test. The rotating ring 261 and the rotation drive the multiple limiting plates 264 to move, so that the ends of stainless steel pipes of 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. In addition, the limiting plate 264 slides on the L-shaped frame 263, so that the ends of stainless steel pipes of different lengths can be abutted and fixed, meeting the fixation of stainless steel pipes of different specifications during the strength test.

[0044] A through groove 271 is circumferentially provided on the outer side of the built-in cylinder 27, and a plurality of circumferentially arranged springs are fixedly installed in the inner cavity of the built-in cylinder 27. A movable frame 272 is fixedly installed on the side of the spring away from the built-in cylinder 27. The movable frame 272 is arranged in a T shape. A support block 274 sliding in the through groove 271 is fixedly installed on one side of the movable frame 272, and an inclined plate 273 is fixedly installed on the other side of the movable frame 272. A threaded rod 275 is threadedly installed on the side away from the two built-in cylinders 27, and the threaded rod 275 is placed between the disc 25 and the rotating frame 26. A conical block 276 located in the inner cavity of the built-in cylinder 27 is fixedly installed at one end of the threaded rod 275.

[0045] After the built-in cylinder 27 is placed into the stainless steel tube, the threaded rod 275 is rotated to drive the conical block 276 to move toward the inclined plate 273. When the conical block 276 moves, multiple inclined plates 273 are pushed outward. Then the inclined plate 273 drives the support block 274 to move out of the through groove 271 through the movable frame 272. Finally, multiple support blocks 274 move away from each other and abut against the inner wall of the stainless steel tube, thereby completing the support for the inside of the stainless steel tube. Compared with the existing device, the present invention can meet the strength test of stainless steel tubes of different diameters and lengths, and can also effectively avoid the sliding of the stainless steel tube during the strength test by internal support and external restriction of the stainless steel tube to be tested.

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

[0047] The detection component includes a support frame 41, on one side of the upper end surface of the support frame 41 are fixedly mounted two symmetrically arranged rear frames 42, a flip plate 43 is installed between the two rear frames 42 for common rotation, a moving groove opened on the support frame 41 is provided between the two rear frames 42, a moving block 44 is slidably installed in the moving groove via an electric slider, and a through opening is opened on the flip plate 43 near the moving block 44.

[0048] An inner rod sliding in the through opening is provided in the middle of the moving block 44, and two symmetrically arranged front frames 45 are fixedly installed on the upper end surface of the support frame 41 away from the rear frame 42. A sliding rod 46 is slidably installed in the middle of the front frame 45, and a knocking frame 48 is fixedly installed on the bottom ends of the two sliding rods 46. A center wheel 47 is fixedly installed between the two front frames 45, and a steel rope is installed between the knocking frame 48 and the flip plate 43, and the steel rope is wound around the center wheel 47.

[0049] When the fixed stainless steel pipe is subjected to strength testing, the electric slider opens to drive the moving block 44 to slide on the support frame 41 toward the rear frame 42. When the moving block 44 slides, it drives the flip plate 43 to flip. When the flip plate 43 flips, the knocking frame 48 is driven 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] A lifting groove 481 is evenly spaced in the middle of the knocking frame 48, and a knocking rod 482 is slidably installed in the middle of the lifting groove 481. After the knocking frame 48 knocks the stainless steel pipe, the height difference between the multiple knocking rods 482 can be observed to quickly observe whether there is a dent on the surface of the stainless steel pipe.

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

[0052] When unloading the stainless steel pipe to be inspected, the motor is turned on to drive the central rod 55 to rotate. When the central rod 55 rotates, the transposition frame 56 is synchronously driven to rotate, thereby realizing 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 frame 56 . The rotation of the transposition frame 56 drives the plurality of partition rods to be transposed so as to receive the stainless steel pipes in the storage box 53 , and finally rolls onto the center plate 2 through the unloading plate 57 .

[0054] When the present invention is in use, the stainless steel pipe 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 pipe. The electric slider is turned on to drive the rotating ring 261 to rotate. When the rotating ring 261 rotates, the push-pull plate 262 drives the L-shaped frame 263 to slide on the rotating frame 26, 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 pipe, 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 of stainless steel pipes of different specifications during the strength test.

[0055] The threaded rod 275 is rotated to drive the conical block 276 to move toward the inclined plate 273. When the conical block 276 moves, it pushes out the multiple inclined plates 273. Then the inclined plate 273 drives the support block 274 to move out of the through groove 271 through the moving frame 272. Finally, the multiple support blocks 274 move away from each other to abut against the inner wall of the stainless steel pipe, thereby completing the support for the inside of the stainless steel pipe. Compared with the existing device, the present invention can meet the strength test of stainless steel pipes of different diameters and lengths, and can also effectively avoid the sliding of the stainless steel pipe during the strength test by internal support and external restriction of the stainless steel pipe to be tested.

[0056] When the strength of the fixed stainless steel pipe is tested, the electric slider is opened to drive the moving block 44 to slide on the support frame 41 toward the rear frame 42, and the moving block 44 drives the flip plate 43 to flip when sliding, and the knocking frame 48 is driven to slide down by the steel rope when the flip plate 43 flips, and the knocking frame 48 knocks on the outer wall of the stainless steel pipe when it moves down, thereby realizing the strength test of the stainless steel pipe, and the lifting and lowering of the abutment plate 14 is driven by rotating the adjusting rod 13, and the lifting and lowering of the abutment plate 14 can further control the lifting range of the rectangular plate 12. Finally, after the stainless steel pipe is knocked, under the action of the spring, the round rod moves up and down in the corrugated groove 11, thereby driving the stainless steel pipe of the center plate 2 to impact up and down, and the height adjustment of the rectangular plate 12 can adjust the elastic force range of the spring, thereby realizing the regulation of the impact force of the stainless steel pipe itself.
