Description

Technical Field

[0001] The invention relates to the technical field of titanium tube elbow processing, and more specifically, to seamless titanium tube elbow processing equipment and a processing method thereof. Background Art

[0002] Titanium pipe elbow, also known as titanium elbow, is a connecting component used in pipeline systems, mainly used to change the flow direction of the pipeline; it is usually made of titanium material, has excellent corrosion resistance, high strength and light weight, and is suitable for various corrosive environments and high temperature and high pressure conditions.

[0003] Among them, according to different standards and application requirements, titanium tube elbows can be divided into many types, such as 90-degree elbows, 45-degree elbows, seamless elbows, welded elbows, etc.; the manufacturing process of titanium tube elbows also includes cold bending, hot bending, hydraulic bending, rolling bending, push bending and spinning bending, etc.; they are widely used in petrochemical, marine engineering, electric power industry, aerospace and medical fields.

[0004] In the prior art, seamless titanium tube elbows are generally manufactured and formed by a push-bending process, and the specific steps are: first, a whole long seamless titanium tube is divided into several short titanium tube blanks, and then the titanium tube blanks are successively put on the core head and pushed forward. When passing through the bull-horn core head at the front end, the titanium tube blank can be pushed into a titanium tube elbow; in this process, the induction heating coil located outside the bull-horn core head will also heat the titanium tube blank to soften the titanium tube blank, so that the titanium tube blank becomes bent under high temperature and high pressure, thereby achieving the purpose of forming the titanium tube elbow.

[0005] However, in this process, since the titanium tube blanks are put on the core head one by one and pushed forward, and the distance between the titanium tube blanks is relatively close, when the titanium tube blanks pass through the heating area of ​​the induction heating coil, the titanium tube blanks will melt and stick together due to the high temperature and high pressure, resulting in the inability to separate the formed elbow and the elbow being formed in time, thereby affecting the production efficiency of the titanium tube elbow.

[0006] At the same time, if the formed elbow and the elbow being formed cannot be separated in time, and there is no supporting mechanism under the formed elbow, the formed elbow will shake in the air due to inertia, causing the formed elbow to pull the elbow being formed, and then the ends of the formed elbow and the elbow being formed that are in contact will deform together, further reducing the production quality of the titanium tube elbow. For this reason, a seamless titanium tube elbow processing equipment and a processing method thereof are proposed to improve the existing problems. Summary of the invention

[0039] The function of the sliding unit 2 is to rotate and divide the positions where the titanium tubes are re-fused due to high temperature and high pressure, thereby avoiding the problem that the titanium tube blanks will melt and stick together due to high temperature and high pressure when passing through the heating area of ​​the induction heating coil, resulting in the inability to separate the formed bend and the bend being formed in time, thereby ensuring the forming of the titanium bend and further improving the production efficiency of the titanium bend.

[0040] The function of the lifting unit 3 is to lift and support the formed titanium bend, avoiding the problem that there is no supporting mechanism under the formed bend, which causes the formed bend to shake in the air due to inertia, causing the formed bend to pull the bend being formed, and then causing the end of the formed bend to deform together with the end of the bend being formed, thereby improving the production quality of the titanium bend.

[0041] See also Figure 1-Figure 3 Specifically, the pushing unit 1 includes an operating table 11, a slide rail 12 symmetrically arranged on the top of the operating table 11 in the axial M direction, an electric slider 13 sliding on the slide rail 12, a slide plate 14 arranged between the electric sliders 13, a limiter 15 arranged on the top of the slide plate 14, a clamping member 16 symmetrically arranged on the top of the operating table 11 in the radial N direction, a main rod core 17 arranged between the clamping members 16, a horn rod core 18 arranged at one end of the main rod core 17, and an induction heating coil 19 sleeved at the connection between the main rod core 17 and the horn rod core 18; the clamping member 16 is used to clamp and support the two ends of the main rod core 17 separately.

[0042] When loading, one of the clamping parts 16 will first clamp and support one end of the main rod core 17, and then the staff will put several short strips of titanium tube blanks on the main rod core 17 from the end that has not been clamped, so that the titanium tube blanks on the main rod core 17 fit tightly, thereby realizing the loading of the titanium tube blanks.

[0043] When the titanium tube blank begins to be pushed, another clamping piece 16 will clamp and support the other end of the main rod core 17, and the previous clamping piece 16 will be loosened. At this time, the electric slider 13 starts, driving the slide plate 14 and the limit piece 15 to slide along the distribution direction of the slide rail 12; during this process, the limit piece 15 starts and approaches the outer wall of the main rod core 17, but does not clamp the main rod core 17, so that the limit piece 15 pushes the titanium tube blank on the main rod core 17 during the sliding process, so that the titanium tube blank enters the horn rod core 18 along the main rod core 17 for pushing and forming. During this process, the induction heating coil 19 starts to heat the titanium tube blank being pushed and the titanium tube blank to be pushed.

[0044] See also Figure 4-Figure 5 Specifically, the rowing unit 2 is arranged at one end of the operating table 11, and includes a support plate 21, a ring rail 22 arranged on the top of the support plate 21, an electric ring block 23 that slides evenly on the ring rail 22, a fixed disk 24 arranged above the support plate 21, a row of slices 25 that is evenly rotated and connected to the fixed disk 24, a rotating disk 26 arranged above the fixed disk 24, a pushing cylinder 27 arranged on one side of the rotating disk 26, an electric telescopic rod 28 arranged at the telescopic end of the pushing cylinder 27, and a fixed pile 29 that is rotatably connected to the telescopic end of the electric telescopic rod 28.

[0045] Among them, when the final push of the bent pipe is completed, the push cylinder 27 is started, and the electric telescopic rod 28 is pushed out, so that the electric telescopic rod 28 drives the rotating disk 26 to rotate through the fixed pile 29. In this process, the electric telescopic rod 28 is also started, and its telescopic end is extended along the rotation direction of the fixed pile 29; thereby, a plurality of scribers 25 can be rotated in the fixed disk 24 and approach each other, and the position where the bent pipes are fused due to high temperature and high pressure is squeezed and clamped; then the electric ring blocks 23 are all started, driving the fixed disk 24 to rotate in a circle along the distribution direction of the ring track 22, and a plurality of scribers 25 are also rotated accordingly, so that the scribers 25 can rotate and divide the position where the titanium tubes are re-fused due to high temperature and high pressure, avoiding the melting and bonding phenomenon between the titanium tube blanks due to high temperature and high pressure when the titanium tube blanks pass through the heating area of ​​the induction heating coil, resulting in the problem that the formed bent pipe and the formed bent pipe cannot be separated in time, thereby ensuring the forming of the titanium bent pipe, thereby improving the production efficiency of the titanium bent pipe.

[0047] Among them, the adjusting member 35 is used to support the lifting member 36 and adjust the rotation angle of the lifting member 36. The lifting member 36 is used to lift the formed titanium bent pipe; specifically, in the process of gradually pushing the titanium pipe billet into a bent pipe, the adjusting member 35 is started, driving the lifting member 36 to approach the bent pipe being formed, and lifting the bent pipe, thereby avoiding the situation where there is no supporting mechanism under the formed bent pipe, causing the formed bent pipe to shake in the air due to inertia, causing the formed bent pipe to pull the bent pipe being formed, and then causing the formed bent pipe and the end of the bent pipe in contact with the bent pipe being formed to deform together, thereby improving the production quality of the titanium bent pipe.

[0049] Among them, the limit cylinder 151 is started, driving the two limit plates 152 to approach the outer wall of the main rod core 17, but not clamping the main rod core 17, so that the limit member 15 pushes the titanium tube blank on the main rod core 17 during the sliding process, so that the titanium tube blank enters the ox horn rod core 18 along the main rod core 17 for pushing and molding.

[0050] See also Figure 1-Figure 3 Furthermore, the clamping member 16 includes a base 161, a telescopic cylinder 162 rotatably connected to the top of the base 161, a special-shaped plate 163 rotatably connected to the telescopic end of the telescopic cylinder 162, a connecting rod 164 rotatably connected to the end of the special-shaped plate 163 away from the telescopic cylinder 162, a swing bar 165 rotatably connected to the top of the base 161 in the axial M direction, and an arc plate 166 arranged on the side wall of the swing bar 165; the special-shaped plate 163 is L-shaped, one end of the swing bar 165 away from the base 161 is rotatably connected to the corner side wall of the special-shaped plate 163, and the other end of the swing bar 165 away from the base 161 is rotatably connected to the outer wall of the special-shaped plate 163 away from the connecting rod 164, the two arc plates 166 are relatively distributed, and the main rod core 17 is located between the arc plates 166.

[0051] Among them, the telescopic cylinder 162 is started to pull the special-shaped plate 163 to rotate. On the one hand, the special-shaped plate 163 can push one of the swing bars 165 to rotate and approach the main rod core 17, and the corresponding arc plate 166 also approaches synchronously. On the other hand, the other swing bar 165 can be pulled to rotate and approach the main rod core 17 through the connecting rod 164, and the corresponding arc plate 166 also approaches synchronously, so that the two arc plates 166 can clamp the main rod core 17, thereby achieving the purpose of clamping and fixing.

[0052] See also Figure 4-Figure 5 Furthermore, one end of the support plate 21 is connected to one end of the operating table 11, a through hole 211 is opened on the top of the support plate 21, the ring rail 22 is concentrically distributed with the through hole 211, the end of the horn rod core 18 away from the main rod core 17 is located above the through hole 211, and the side of the electric ring block 23 away from the ring rail 22 is connected to the bottom of the fixed plate 24.

[0053] The formed bent pipe will pass through the through hole 211 , the fixing hole 242 and the through hole 262 to reach the supporting member 36 .

[0054] See also Figure 4-Figure 5 Furthermore, a fixing groove 241 is provided on the top of the fixing disk 24, and a fixing hole 242 is provided in the fixing groove 241. The fixing hole 242 is concentrically distributed with the through hole 211. The scriber 25 is located in the fixing groove 241 and is overlapped and staggered. The side wall at one end of the scriber 25 is rotatably connected to the inner bottom of the fixing groove 241. A movable column 251 is provided on the side wall of the scriber 25 away from the fixing groove 241. The movable column 251 is located at the other end of the scriber 25; the rotating disk 26 can be plugged in and out of the fixing groove 241, and movable grooves 261 are evenly provided on the top of the rotating disk 26. The movable column 251 can be plugged in and out of the corresponding movable grooves 261.

[0055] See also Figure 4-Figure 5 Furthermore, a through hole 262 is provided on the top of the rotating disk 26, and the through hole 262 is concentrically distributed with the fixing hole 242. The pushing cylinder 27 is located on the top of the fixing disk 24, and the pushing cylinder 27 and the electric telescopic rod 28 are vertically distributed. One end of the fixing pile 29 is connected to the top of the rotating disk 26.

[0056] Among them, during the rotation of the rotating disk 26 in the fixed groove 241, since the side wall of one end of the dicing blade 25 is rotatably connected to the inner bottom of the fixed groove 241, a movable column 251 is provided on the side wall of the dicing blade 25 away from the fixed groove 241, and the movable column 251 is located at the other end of the dicing blade 25. The movable column 251 can be inserted in the corresponding movable groove 261. Therefore, the rotation of the rotating disk 26 will cause the movable column 251 to slide in the corresponding movable groove 261, so that the dicing blade 25 rotates in the fixed groove 241 and approaches each other, and the position where the bent pipes are fused due to high temperature and high pressure is squeezed and clamped, thereby achieving the purpose of cutting, avoiding the titanium tube blanks from melting and bonding due to high temperature and high pressure when passing through the heating area of ​​the induction heating coil, resulting in the problem that the formed bent pipe and the bent pipe being formed cannot be separated in time, thereby ensuring the forming of the titanium bent pipe and further improving the production efficiency of the titanium bent pipe.

[0057] Embodiment 2: Through the technical solution of embodiment 1, although the problem in the prior art that the titanium tube blanks will melt and bond due to high temperature and high pressure, resulting in the inability to separate the formed bend tube from the forming bend tube in time, is solved, however, the problem that there is no supporting mechanism under the formed bend tube, resulting in the formed bend tube shaking in the air due to inertia, causing the formed bend tube to pull the forming bend tube, and then causing the ends of the formed bend tube and the forming bend tube in contact to deform together is not solved; therefore, the following solution is proposed:

[0058] See also Figure 6-Figure 7 Furthermore, the adjusting member 35 includes an adjusting motor 351, an adjusting gear 352 arranged at the output end of the adjusting motor 351, racks 353 symmetrically arranged on both sides of the adjusting gear 352 in the radial N direction, and an adjusting plate 354 arranged on the side wall of the rack 353 away from the adjusting gear 352; a cavity 341 is opened at the top of the vertical plate 34, the output end of the adjusting motor 351 passes through the side wall of the vertical plate 34, and extends into the cavity 341 to be connected to the adjusting gear 352, the racks 353 are staggered, and one end of the adjusting plate 354 is inserted into the cavity 341.

[0059] Among them, in the process of gradually pushing the titanium tube billet into a bent tube, the adjusting motor 351 is started, driving the adjusting gear 352 to rotate. Due to the staggered distribution between the racks 353, there will be a height difference between the two racks 353 as the adjusting gear 352 rotates, thereby causing a height difference between the two adjusting plates 354, and then causing the lifting plate 361 to tilt, which can better fit the state of the titanium bent tube falling and forming, which is beneficial to the forming of the titanium bent tube.

[0060] See also Figure 6-Figure 7 Furthermore, the lifting member 36 includes a lifting plate 361, a roller 362 that is evenly rotatably connected to the lifting plate 361, electric arc blocks 363 symmetrically arranged on both sides of the lifting plate 361, and a horizontal plate 364 arranged between the electric arc blocks 363; the lifting plate 361 is arc-shaped, and the end of the adjustment plate 354 away from the cavity 341 is rotatably connected to the bottom of the lifting plate 361, and a roller groove 365 is opened on the top of the lifting plate 361, and the roller 362 is located in the roller groove 365. Arc grooves 366 are also symmetrically opened on both sides of the top of the lifting plate 361, and the electric arc blocks 363 cooperate to slide in the corresponding arc grooves 366.

[0061] Among them, when the titanium bent pipe falls, it will first fit with the cross plate 364 and drive the roller 362 to roll, reducing the friction; as the angle changes during the forming process of the titanium bent pipe, the electric arc block 363 starts, driving the cross plate 364 to slide along the opening direction of the arc groove 366, so that the cross plate 364 always maintains the fit and support of the titanium bent pipe. At the same time, the cross plate 364 can also slide along the opening direction of the arc groove 366 as the angle changes during the forming process of the titanium bent pipe. Therefore, through the mutual cooperation of the adjustment member 35 and the lifting member 36, the formed titanium bent pipe can be lifted and supported, avoiding the lack of any supporting mechanism under the formed bent pipe, resulting in the formed bent pipe shaking in the air due to inertia, causing the formed bent pipe to pull the bent pipe being formed, and then causing the formed bent pipe and the end of the bent pipe in contact with the bent pipe being formed to deform together, thereby improving the production quality of the titanium bent pipe.

[0062] Embodiment 3, a method for processing a seamless titanium tube elbow, using the seamless titanium tube elbow processing equipment as described above, comprises the following steps:

[0063] S1. During loading, one of the clamping members 16 will first clamp and support one end of the main rod core 17, and then the staff will put several short strips of titanium tube blanks on the main rod core 17 from the end that has not been clamped, so that the titanium tube blanks on the main rod core 17 fit tightly, thereby realizing the loading of the titanium tube blanks.

[0064] S2. When the titanium tube blank starts to be pushed, another clamping member 16 will clamp and support the other end of the main rod core 17, and the previous clamping member 16 will be released. At this time, the electric slider 13 starts, driving the slide plate 14 and the limit member 15 to slide along the distribution direction of the slide rail 12; during this process, the limit member 15 starts and approaches the outer wall of the main rod core 17, but does not clamp the main rod core 17, so that the limit member 15 pushes the titanium tube blank on the main rod core 17 during the sliding process, so that the titanium tube blank enters the horn rod core 18 along the main rod core 17 for pushing and forming.
