Description

Technical Field

[0001] The present invention relates to the technical field of pipes, and in particular to a device and a method for detecting the strength of an annular section of a large-diameter TA31 pipe. Background Art

[0002] TA31 pipes are mainly composed of titanium and other alloying elements. Titanium itself has the characteristics of low density and high strength. TA31 alloys may also contain alloying elements such as aluminum and vanadium. Aluminum can improve the strength and heat resistance of titanium alloys, and vanadium can improve the toughness and processing performance of alloys. The combined effect of these alloying elements makes TA31 pipes have good comprehensive performance. Pipes will be subjected to various types of loads during actual use. In the production process of pipes, cross-sectional strength testing is an important means of quality control. Pipe manufacturers need to ensure that their products meet relevant industry standards and specifications. Through testing, products that do not meet the strength requirements can be screened out to ensure the consistency and stability of product quality. At the same time, in the procurement and acceptance of pipes, the results of cross-sectional strength testing are also an important basis for judging whether the pipes are qualified, such as internal pressure (for pipes that transport liquids or gases), external pressure (buried pipes are subjected to soil pressure, etc.), axial tension (for example, during the thermal expansion and contraction of the pipeline system) or bending force (when there are bends in the pipeline layout, etc.). Through cross-sectional strength testing, it can be determined whether the pipe can safely withstand these expected loads, thus avoiding safety accidents such as rupture and excessive deformation of the pipe during use.

[0003] The existing TA31 pipe inspection equipment has low inspection efficiency and few inspection aspects, so a new design was made to address this situation. Summary of the invention

The bevel plate is designed with an inclined amplitude to achieve the concentration of force on the pipe during the extrusion process, reduce the movement of the pipe, and improve the stability of the operation. Auxiliary rods are fixedly connected on both sides of the top of the pressing plate to avoid uneven force on the pipe during the pressing process. The auxiliary rods play a role of assisting the pressing. A limiting mechanism is fixedly connected to one side of the composite base close to the processing mechanism. By placing the pipe inside the processing mechanism and constraining the pipe space through the limiting mechanism, the pipe movement during the inspection process is avoided, and danger to the staff is avoided, thereby maintaining the normal operation of the equipment.

[0005] Preferably, the fixing mechanism includes a fixed base, and a motor is fixedly connected to one side of the outside of the fixed base. The motor can be rotated forward and reversely in a manner similar to a servo motor. Two fixing mechanisms are provided. When the fixing mechanisms on both sides slide on the surface of the slide block to fix the pipe according to the length of the pipe, one side of the motor rotates clockwise and the other side of the motor rotates counterclockwise, so as to detect the distortion of the pipe and prevent problems with the toughness of the pipe.

[0006] Preferably, a silicone block is fixedly connected to one side of the outside of the hydraulic block. The silicone block is made of silicone material. The silicone material increases the buffering effect to avoid excessive pressure in the process of supporting the pipe, which leads to wear of the pipe, thereby increasing the wear of the pipe and components. A block surface groove is provided on the side of the outside of the silicone block away from the hydraulic block. By providing the block surface groove and increasing the contact area through grooving, a certain anti-slip effect is achieved and the fixing effect is improved.

[0007] Preferably, the limiting mechanism includes a friction base plate, and an electric push rod is fixedly connected to one side of the outer side of the friction base plate. The angle of the support plate is controlled by the electric push rod so that the friction mechanism fits against the surface of the pipe, thereby limiting the activity space of the pipe and avoiding shaking during some detection processes, which affects the subsequent detection effect. The side of the electric push rod away from the friction base plate is fixedly connected to the support plate, and the side of the support plate is slidably connected to a sliding rod. The side of the sliding rod away from the support plate is fixedly connected to the friction mechanism. During the process of pipe pressure detection, the surface of the pipe extends outward, which causes the sliding rod to be squeezed and the spring bar to contract, thereby achieving the effect of shock absorption and buffering, reducing the amplitude of the components, maintaining the stability of the components, and avoiding contraction of the components. At the same time, when the pipe rotates and rubs against the friction mechanism, it also has a shock absorption effect. A spring bar is sleeved on the side of the sliding rod close to the friction mechanism.

In the process of controlling the clockwise rotation of the tube by the fixing mechanism, the tube and the friction column are rubbed, so as to achieve the wear resistance test of the tube surface, prevent scratches and holes from appearing in the subsequent use of the tube, thereby detecting the use quality of the tube. A cylindrical groove is provided on the outer side of the friction column. By providing the cylindrical groove, a certain heat dissipation effect is achieved through the grooving, which avoids excessive friction and causing the temperature of the component to be too high, thereby affecting the performance of the component, and surface chip removal and impurity removal are removed to prevent affecting the subsequent friction effect.

[0010] Preferably, the cleaning mechanism includes a cleaning shell, and a cylindrical block is rotatably connected to the middle of the inner wall of the cleaning shell. The cylindrical block rubs against the surface of the pipe to scratch the surface of the pipe, clean up excess impurities and oil stains, and prevent the oil stains from causing parts to slide during the extrusion process, thereby affecting the detection effect. A strip groove is provided on the outer side of the columnar block. By providing the strip groove, the contact area is increased through the grooving, thereby improving the friction effect, increasing the cleaning effect, and at the same time improving the chip removal effect and reducing impurity adsorption.

[0011] Preferably, a support frame is fixedly connected to one side of the inner wall of the cleaning shell, and a friction plate is fixedly connected to the outside of the support frame near the cylindrical block. During the rotation of the cylindrical block, it rubs against the surface of the friction plate to achieve the cleaning function of the component, thereby achieving a self-cleaning effect of the component, preventing impurities from sticking to the component and causing corrosion, thereby affecting the service life of the component. A spring rod is fixedly connected to the inner side of the support frame, which plays a shock-absorbing and buffering role, reducing the amplitude generated by the friction between the friction plate and the cylindrical block, thereby maintaining the stability of the cleaning.

[0012] A method for detecting the strength of an annular section of a large-diameter TA31 pipe comprises the following steps: Step 1: Fixing: The pipe is fixed by sliding the fixing mechanism on the outside of the slide rail block; Step 2: cleaning: the pipe is rotated by the fixing mechanism so that the pipe rubs against the outside of the treatment mechanism to clean the surface of the pipe; Step three, friction, the pipe is driven to rotate by the fixing mechanism, and the pipe rubs against the outer side of the limiting mechanism to detect the hardness of the pipe; Step 4: Pressing: the pressing plate is controlled by a hydraulic rod to squeeze the pipe and the strength of the annular section of the pipe is tested; Step five, taking out the material, fixing the pipe by releasing the fixing mechanism to take out the pipe.

[0013] The present invention provides a ring section strength testing device for large-diameter TA31 pipes. It has the following beneficial effects: 1. The large-diameter TA31 pipe annular section strength testing equipment is designed with a composite mechanism. By placing the pipe inside the processing mechanism and constraining the pipe space through the limiting mechanism, the movement of the pipe during the inspection is avoided, and danger to the staff is avoided, thereby maintaining the normal operation of the equipment. The fixing mechanism is set on both sides of the pipe. The fixing mechanism controls the pipe to rotate and rubs with the processing mechanism to achieve the effect of cleaning the surface of the pipe and avoid the stains on the surface of the pipe affecting the detection effect. The pressing plate is controlled by the hydraulic rod to squeeze the surface of the pipe to achieve the detection effect of the annular section strength of the pipe. Secondly, in the process of pressing down, the pipe is prevented from being unevenly stressed, and the auxiliary rod is used to assist in pressing down. The bevel plate is made of plastic material to increase the friction on the surface of the pipe, avoid shaking of the pipe during the pressing process, and reduce the wear between the components and the pipe, thereby extending the service life of the components. The bevel plate adopts an inclined amplitude design to achieve the process of squeezing the pipe, which promotes the concentration of force on the pipe, reduces the movement of the pipe, and improves the stability of the operation.

[0014] 2. The annular section strength testing equipment for large-diameter TA31 pipes is designed with a fixing mechanism. The hydraulic block slides around on the inner side of the hydraulic base, and supports the inner wall of the pipe to fix the pipe. The motor can be rotated forward and reversely similar to a servo motor. There are two fixing mechanisms. When the fixing mechanisms on both sides slide on the surface of the slide block to fix the pipe according to the length of the pipe, one motor rotates clockwise and the other motor rotates counterclockwise, so as to detect the distortion of the pipe and prevent problems with the toughness of the pipe. The silicone block is made of silicone material, and the silicone material increases the buffering effect to avoid excessive pressure in the process of supporting the pipe, which causes wear of the pipe, thereby increasing the wear of the pipe and components. By opening grooves on the block surface and increasing the contact area through grooving, a certain anti-slip effect is achieved, thereby improving the fixing effect.

[0015] 3. The annular section strength testing equipment for large-diameter TA31 pipes is designed with a limiting mechanism. The angle of the support plate is controlled by an electric push rod so that the friction mechanism fits the surface of the pipe, thereby limiting the activity space of the pipe and avoiding shaking during some inspections, which affects the subsequent inspection results. Secondly, during the pipe pressure inspection, the pipe surface extends outward, causing the sliding rod to be squeezed and the spring bar to shrink, thereby achieving a shock-absorbing and buffering effect, reducing the amplitude of the components, maintaining the stability of the components, and avoiding component shrinkage. At the same time, when the pipe rotates and rubs against the friction mechanism, it also has a shock-absorbing effect.

[0016] Fourth, the annular section strength testing equipment for large-diameter TA31 pipes is designed with a processing mechanism to support the pipes through a receiving plate to prevent the gravity generated by the pipes from causing the sliding block to squeeze the spring coil on the surface of the connecting rod, thereby achieving the effect of shock absorption and buffering, reducing the vibration caused by placing the pipes, avoiding damage to the components, and facilitating the pipes to quickly reduce the vibration amplitude. When the composite mechanism drives the pipes to rotate, it rubs against the surface of the cleaning mechanism to achieve the effect of cleaning impurities and avoid excessive impurities affecting the detection effect.

[0017] 5. The annular section strength testing equipment for large-diameter TA31 pipes is designed with a cleaning mechanism. The cylindrical block rubs against the surface of the pipe to scratch the surface of the pipe, clean excess impurities and oil stains, and prevent the oil stains from causing the parts to slide during the extrusion process, thereby affecting the testing effect. The strip grooves are opened to increase the contact area, improve the friction effect, increase the cleaning effect, and improve the chip removal effect, reduce impurity adsorption. During the rotation of the cylindrical block, it rubs against the surface of the friction plate to clean the parts, thereby achieving the self-cleaning effect of the parts, preventing impurities from sticking to the parts and corroding them, thereby affecting the service life of the parts. The spring rod plays a role of shock absorption and buffering, reducing the amplitude caused by the friction between the friction plate and the cylindrical block, thereby maintaining the stability of the cleaning.

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.

[0029] The first embodiment, as Figures 1 to 3 As shown, the present invention provides a technical solution: a large-diameter TA31 pipe annular cross-section strength detection device, comprising a composite mechanism 1, the composite mechanism 1 is used to detect the cross-section strength of the pipe; A processing mechanism 2, the processing mechanism 2 is used to clean the pipe; A frame 3, the frame 3 is used to support the composite structure 1; The bottom of the composite mechanism 1 is fixedly connected to the top of the frame 3, and the inside of the composite mechanism 1 is fixedly connected to the bottom of the processing mechanism 2; Among them, the composite mechanism 1 includes a composite base 11, the middle of the top of the composite base 11 is fixedly connected to the bottom of the processing mechanism 2, a slide block 13 is fixedly connected to the side of the top of the composite base 11 close to the processing mechanism 2, and a fixing mechanism 14 is slidably connected to the outside of the slide block 13, and a composite top plate 12 is fixedly connected to the edge of the top of the composite base 11, a hydraulic rod 16 is fixedly connected to the side of the outside of the composite top plate 12 close to the composite base 11, a pressing plate 18 is fixedly connected to the side of the outside of the hydraulic rod 16 away from the composite top plate 12, a chamfered plate 19 is fixedly connected to the side of the outside of the pressing plate 18 away from the hydraulic rod 16, auxiliary rods 17 are fixedly connected on both sides of the top of the pressing plate 18, and a limiting mechanism 15 is fixedly connected to the side of the outside of the composite base 11 close to the processing mechanism 2. By placing the pipe inside the processing mechanism 2 and constraining the pipe space through the limiting mechanism 15, the movement of the pipe during the inspection process is avoided, and danger to the staff is avoided, thereby maintaining the normal operation of the equipment. The fixing mechanism 14 is arranged on both sides of the pipe. The fixing mechanism 14 controls the pipe to rotate and rub against the processing mechanism 2, so as to achieve the effect of cleaning the surface of the pipe and avoid the stains on the surface of the pipe affecting the detection effect. The pressing plate 18 is controlled by the hydraulic rod 16 to squeeze the surface of the pipe, so as to achieve the detection effect of the strength of the annular section of the pipe. Secondly, in the process of pressing down, uneven force on the pipe is avoided, and the auxiliary rod 17 plays an auxiliary role in pressing down. The bevel plate 19 is made of plastic material to increase the friction on the surface of the pipe, avoid shaking of the pipe during the pressing process, and reduce the wear between the components and the pipe, thereby extending the service life of the components. The bevel plate 19 adopts an inclined amplitude design, so as to achieve the process of squeezing the pipe, promote the concentration of force on the pipe, reduce the movement of the pipe, and improve the stability of the operation.

[0030] The second embodiment is based on the first embodiment. Figures 4 to 6 As shown, the fixing mechanism 14 includes a fixing base 141, a motor 142 is fixedly connected to one side of the outside of the fixing base 141, a hydraulic base 143 is rotatably connected to one side of the outside of the fixing base 141 away from the motor 142, and a hydraulic block 144 is slidably connected to one side of the hydraulic base 143 away from the fixing base 141. The hydraulic block 144 slides around the inside of the hydraulic base 143 to support the inner wall of the pipe, thereby achieving the function of fixing the pipe. The motor 142 can be rotated forward and backward like a servo motor. Two fixing mechanisms 14 are provided. When the fixing mechanisms 14 on both sides slide on the surface of the slide rail block 13 to fix the pipe according to the length of the pipe, the motor 142 on one side rotates clockwise and the motor 142 on the other side rotates counterclockwise, thereby achieving the detection of pipe distortion and preventing problems with pipe toughness.

[0031] A silicone block 145 is fixedly connected to one side of the outside of the hydraulic block 144, and a block surface groove 146 is provided on one side of the outside of the silicone block 145 away from the hydraulic block 144. The silicone block 145 is made of silicone material, and the silicone material increases the buffering effect to avoid excessive pressure in the process of supporting the pipe, thereby increasing the wear of the pipe and components. By providing the block surface groove 146 and increasing the contact area through grooving, a certain anti-slip effect is achieved, and the fixing effect is improved.

[0032] The limiting mechanism 15 includes a friction base plate 151, an electric push rod 152 is fixedly connected to one side of the outside of the friction base plate 151, a support plate 153 is fixedly connected to one side of the outside of the electric push rod 152 away from the friction base plate 151, a sliding rod 154 is slidably connected to one side of the outside of the support plate 153, a friction mechanism 156 is fixedly connected to one side of the outside of the sliding rod 154 away from the support plate 153, and a spring bar 155 is sleeved on one side of the outside of the sliding rod 154 close to the friction mechanism 156. The angle of the support plate 153 is controlled by the electric push rod 152 so that the friction mechanism 156 fits against the surface of the pipe, thereby limiting the activity space of the pipe and avoiding shaking during some inspection processes, which affects the subsequent inspection results. Secondly, during the pipe pressure inspection, the pipe surface extends outward, causing the sliding rod 154 to be squeezed to cause the spring bar 155 to contract, thereby achieving a shock-absorbing and buffering effect, reducing the amplitude of the components, maintaining the stability of the components, and avoiding component contraction. At the same time, when the pipe rotates and rubs against the friction mechanism 156, it also has a shock-absorbing effect.

[0033] The friction mechanism 156 includes an arc plate 1561, and a connecting block 1562 is fixedly connected to the side of the arc plate 1561 away from the sliding rod 154. A friction column 1563 is rotatably connected between the opposite surfaces of the connecting block 1562, and a cylindrical groove 1564 is provided on the outer side of the friction column 1563.

[0034] The third embodiment is based on the first and second embodiments. Figure 7 and Figure 8As shown, the processing mechanism 2 includes a processing base plate 21, a plate surface groove 22 is provided on one side of the outside of the processing base plate 21, a connecting rod 23 is fixedly connected to the inner side of the plate surface groove 22, a spring ring 24 is sleeved on the outer side of the connecting rod 23, a sliding block 25 is slidably connected to the outer side of the connecting rod 23, a receiving plate 26 is fixedly connected to one side of the outside of the sliding block 25, a plate surface cutout 27 is provided on one side of the outside of the receiving plate 26, and a cleaning mechanism 28 is fixedly connected to the middle between the opposite surfaces of the processing base plate 21. The receiving plate 26 supports the pipe, and the gravity generated by the placement of the pipe causes the sliding block 25 to squeeze the spring ring 24 on the surface of the connecting rod 23, thereby achieving the effect of shock absorption and buffering, reducing the vibration generated by the placement of the pipe, avoiding damage to the components, and facilitating the rapid reduction of the vibration amplitude of the pipe. When the composite mechanism 1 drives the pipe to rotate, it rubs against the surface of the cleaning mechanism 28, thereby achieving the effect of cleaning impurities, avoiding excessive impurities affecting the detection effect.

[0035] The cleaning mechanism 28 includes a cleaning shell 281, and a cylindrical block 282 is rotatably connected to the middle of the inner wall of the cleaning shell 281, and a strip groove 283 is provided on the outer side of the cylindrical block 282. The cylindrical block 282 rubs against the surface of the pipe to scrape the surface of the pipe, clean up excess impurities and oil stains, and prevent the oil stains from causing the parts to slide during the extrusion process, thereby affecting the detection effect. By opening the strip groove 283, the contact area is increased by grooving, the friction effect is improved, the cleaning effect is increased, and the chip removal effect is improved, and the impurity adsorption is reduced.

[0036] A support frame 284 is fixedly connected to one side of the inner wall of the cleaning housing 281, a friction plate 286 is fixedly connected to the outer side of the support frame 284 near the cylindrical block 282, and a spring rod 285 is fixedly connected to the inner side of the support frame 284. During the rotation of the cylindrical block 282, friction is performed with the surface of the friction plate 286, thereby achieving the function of cleaning the components, thereby achieving the self-cleaning effect of the components, preventing impurities from sticking to the components and causing corrosion, thereby affecting the service life of the components, and the spring rod 285 plays a role of shock absorption and buffering, reducing the amplitude generated by the friction between the friction plate 286 and the cylindrical block 282, thereby maintaining the stability of cleaning.

[0037] A method for testing the strength of the annular section of a large-diameter TA31 pipe, such as Fig. 9 As shown, the following steps are included: Step 1: Fixing: The fixing mechanism 14 slides outside the slide rail block 13 to fix the pipe; Step 2: cleaning: the pipe is rotated by the fixing mechanism 14 so that the pipe rubs against the outside of the processing mechanism 2 to clean the surface of the pipe; Step 3: friction, the fixing mechanism 14 drives the pipe to rotate, and the pipe rubs against the outer side of the limiting mechanism 15 to detect the hardness of the pipe; Step 4: Pressing: the hydraulic rod 16 controls the pressing plate 18 to squeeze the pipe and test the strength of the pipe's annular section; Step five, taking out the material, fixing the pipe by releasing the fixing mechanism 14 to take out the pipe.

[0038] When in use, the staff will place the pipe inside the processing mechanism 2, and the processing mechanism 2 will play a role of shock absorption and buffering, reduce the amplitude of the pipe, speed up the stability of the components, and facilitate subsequent operations. The processing mechanism 2 is set in the middle of the top of the composite base 11 inside the composite mechanism 1, and the pipe is supported by the fixing mechanism 14 inside the composite mechanism 1, so as to maintain the stability of the equipment and avoid shaking during the detection process to affect subsequent operations. A cleaning mechanism 28 is also set inside the processing mechanism 2, and the pipe is controlled by the fixing mechanism 14. The pipe is rotated so that the pipe and the cleaning mechanism 28 rub against each other, thereby achieving the effect of scratching the pipe surface, cleaning the impurities on the pipe surface, avoiding excessive oil stains on the pipe surface, and preventing the subsequent impact on the detection effect. After the pipe is cleaned, the electric push rod 152 inside the limiting mechanism 15 controls the support plate 153 to make the friction mechanism 156 fit on the pipe surface, so that the pipe and the friction mechanism 156 are frictionally adapted, so that the pipe surface and the friction mechanism 156 are rubbed, thereby realizing the detection of the wear resistance of the pipe, avoiding In order to improve the safety of the pipe, the fixing mechanism 14 is arranged on both sides of the pipe. Secondly, the two fixing mechanisms 14 are respectively provided with motors 142. The motors 142 are similar to servo motors and can rotate counterclockwise and clockwise. After the friction test on the surface of the pipe, the fixing mechanism 14 on one side rotates counterclockwise and the fixing mechanism 14 on the other side rotates clockwise, so as to detect the distortion of the pipe, thereby understanding the toughness of the pipe and avoiding deformation of the pipe in subsequent operations. After stopping rotation and support, the pipe moves to the outside of the processing mechanism 2, and the pressing plate 18 is controlled by the hydraulic rod 16 inside the composite mechanism 1 to extrude the pipe, so as to achieve the effect of detecting the strength of the annular section of the pipe. Secondly, in the process of pressing down, the pipe is prevented from being subjected to uneven force, and the auxiliary rod 17 plays an auxiliary role in pressing down. The bevel plate 19 is made of plastic material to increase the friction on the surface of the pipe, avoid shaking of the pipe during the pressing process, and reduce the wear between the components and the pipe, thereby extending the service life of the components, and then the pipe is taken out.
