Description

Technical Field

[0001] This invention relates to the field of seamless tube forming technology, specifically to a forming device and method for forming seamless titanium alloy tubes for ships. Background Technology

[0002] Seamless steel pipe is one of the important raw materials for national economic development. It is a relatively economical type of steel and has been widely used in industries such as chemical, petroleum, power, machinery, coal, military, and aerospace. Seamless metal pipes have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, coal gas, water, and certain solid materials. Compared with solid pipes, hollow pipes are lighter in weight while maintaining the same bending and torsional strength, making them an economical cross-section material. They are widely used in the manufacture of structural components and mechanical parts, improving material utilization and saving materials and processing time.

[0003] Patent application CN201810311130.5 discloses a flexible forming device for producing seamless metal tubes. It mainly includes a frame base, frame, frame columns, frame beams, ladle, curved metal plate, screw fixing mechanism, screw, side sealing plate, balancing mechanism, roller support, wedge block, wedge block adjusting frame, connecting shaft A, connecting shaft B, baffle, bearing seat A, tube forming device, hyperbolic roll shaft, and mandrel roll shaft. By adjusting the horizontal tilt angle of the hyperbolic roll shaft and mandrel roll shaft, a wide range of finished product wall thickness specifications can be achieved. The horizontal displacement difference between the positions of the hyperbolic roll shaft and mandrel roll shaft can be adjusted. Combined with the screw's angle adjustment, the balancing mechanism, the connecting shaft B's roll gap adjustment, and the tube forming device's positional arrangement, the diameter of the formed tube can be adjusted, resulting in a wide range of finished product diameter specifications. This device saves energy and improves production efficiency.

[0004] While existing equipment can quickly form seamless tubes from raw materials through extrusion, the raw materials tend to expand outwards during the extrusion process, making it difficult to control the shape of the seamless tubes and meet actual production needs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a forming apparatus and method for seamless titanium alloy tubes used in ships, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a seamless titanium alloy tube forming device for ships, comprising a base plate, a discharge plate fixedly connected to the top of the base plate, a base fixedly connected to the top of the base plate, a pushing device fixedly connected to the top of the base, a pushing column fixedly connected to the front end of the pushing device, a roller rotatably connected to the inside of the base via a bearing, a feeding mechanism fixedly connected to the top of the base plate, and a placement mechanism fixedly connected to the top of the base plate.

[0007] The feeding mechanism includes:

[0008] The base has its bottom fixedly connected to a base plate, and its top is fixedly connected to a ramp plate. A connecting rod is provided on the top of the base, and the outer wall of the connecting rod is fixedly connected to the ramp plate. The ramp plate has a protruding part near the base to restrict the movement of raw materials.

[0009] According to the above technical solution, a groove is provided at the front end of the base to provide space for the movement of the movable plate. A push rod is fixedly connected to the top of the base, and a top plate is fixedly connected to the top of the push rod. A roller is rotatably connected to the inner wall of the top plate through a bearing. The roller is used to fix the raw material. By setting the roller, the top of the raw material is clamped and positioned during the processing. The upper and lower support constraints formed by the roller and the roller effectively suppress the radial displacement and shaking of the raw material during the punching process, providing a stable support foundation for punching and subsequent molding processes. From a mechanical positioning perspective, the position of the raw material during processing is guaranteed, ensuring the accurate execution of the extrusion molding operation.

[0010] According to the above technical solution, the outer wall of the connecting rod is rotatably connected to a connecting ring via a bearing, and a right-angle plate is fixedly connected to the outer wall of the connecting ring. A protruding plate is fixedly connected to the top of the right-angle plate, which is used to temporarily block the movement of raw materials.

[0011] According to the above technical solution, a rotating column is fixedly connected to the bottom of the right-angle plate one, and a push rod two is rotatably connected to the outer wall of the rotating column through a bearing. The bottom of the push rod two is rotatably connected to the base through a bearing. The push rod two is used to control the deflection angle of the right-angle plate one.

[0012] According to the above technical solution, the placement mechanism includes a base plate two, a side plate fixedly connected to the top of the base plate two, a roller three rotatably connected to the inner wall of the top of the side plate via a bearing, a motor fixedly connected to the outer wall of the side plate, the output end of the motor fixedly connected to the roller three, a pushing device two fixedly connected to the top of the base plate two, a sliding groove one opened on both sides of the bottom of the pushing device two, a central rod fixedly connected to the side of the pushing device two near the side plate, a baffle fixedly connected to the top of the side plate, a track fixedly connected to the top of the base plate two, and an auxiliary component fixedly connected to the top of the base plate two. The central rod is used to extrude the raw material. By setting up the placement mechanism, while the raw material is being extruded and formed, the raw material is driven to rotate synchronously, so that the obstructed part of the raw material in contact with the roller continuously changes, thereby achieving uniform extension and diffusion of the raw material, avoiding the problem of unidirectional excessive extension of the raw material in the traditional extrusion process. After processing, the seamless tube is limited by the baffle and will continue to rotate with the roller on the placement mechanism. The flatness of the outer wall of the tube is further optimized by the hot rolling process, improving the finished product effect.

[0013] According to the above technical solution, a push rod three is fixedly connected to the top of the base plate two. A right-angle plate two is fixedly connected to the end of the push rod three near the pushing device two. A connecting column is fixedly connected to the end of the right-angle plate two away from the push rod three. The outer wall of the connecting column is movably connected to the slide groove one. A movable plate one is fixedly connected to the outer wall of the connecting column. The bottom of the movable plate one is movably connected to the track. A protruding plate two is fixedly connected to the top of the movable plate one. The protruding plate two controls the height of the auxiliary component by extrusion. By setting a placement mechanism, during the process of driving the raw material to move and extruding through the central rod, the support structure of the auxiliary component is simultaneously triggered to unload sequentially. This ensures that the bottom support force of the auxiliary component is dynamically removed during the processing of the raw material, avoiding contact interference between the auxiliary component and the forming raw material, thereby effectively ensuring the smoothness of movement and structural stability of the equipment during continuous processing.

[0014] According to the above technical solution, the auxiliary component includes a sliding column, a movable plate two is provided at the top of the sliding column, and a circular hole is opened at the bottom of the movable plate two. The inner wall of the circular hole is movably connected to the sliding column, and a force-receiving roller is rotatably connected to the outer wall of the movable plate two through a bearing. A spring is sleeved on the outer wall of the circular hole, the top of the spring is fixedly connected to the movable plate two, and the bottom of the spring is fixedly connected to the base plate two. The movable plate two is used to support the center rod before the raw material moves above the roller three. By setting the auxiliary component, when the equipment pushes out the center rod, it forms multi-point balanced support for the center rod, effectively avoiding the problem of gravity sagging caused by the long extension of the center rod, preventing it from radially shifting during processing, ensuring that the center rod and the raw material axis remain coaxial, thereby controlling the centering positioning of the seamless tube's circular hole, ensuring the stability of the accuracy during the tube forming process, and improving the processing quality.

[0015] A method for forming seamless titanium alloy tubes for shipbuilding includes the following steps:

[0016] S1. When the raw material needs to be processed into a seamless tube, the raw material needs to be heated first. Then, the heated raw material is placed above the right angle plate. After it is placed above the right angle plate, the push rod is activated to drive the right angle plate to deflect downward. The deflected right angle plate will make the protrusion plate no longer able to block the downward movement of the raw material. The push from behind the right angle plate will drive the raw material to fall onto the roller along the trajectory of the ramp plate.

[0017] S2. After the raw material is placed on roller one, push rod one is activated to lower the top plate, and roller two presses down on the raw material to clamp and fix it, ensuring that the raw material will not shift during processing. Then push device two is activated to push out the center rod. After that, push device one is activated to push the push column forward. The moving push column will push the raw material forward. At this time, the raw material is pressed and contacted by the center rod under the push of the push column. Under the pressure of the center rod, a hole is opened in the center of the raw material. While the raw material is pushed forward, push rod three will drive the protruding plate two to move forward along the track. As the protruding plate two moves forward along the track, the protruding plate two no longer presses the auxiliary component, and the height of the auxiliary component is reduced to avoid affecting the movement of the raw material.

[0018] S3. When the equipment processes the raw material, the motor drives the three rollers to rotate. The rotating rollers will cause the raw material to rotate together, preventing the compressed raw material from moving in one direction and affecting the shape of the seamless tube. After the processing of the raw material is completed, the center rod is retracted by the push device two. Due to the obstruction of the baffle, the processed raw material will continue to remain on the three rollers. At this time, the three rollers will continue to rotate to further process the surface of the seamless tube. After the processing is completed, the operator uses tools to push the seamless tube out of the equipment.

[0019] S4. After the processed seamless tube is pushed out from above the placement mechanism, first activate push device two and push device one to retract the center rod and push column to facilitate the subsequent loading of raw materials. Then activate push rod three to drive movable plate one to reset. As movable plate one resets, protruding plate two will be placed back at the bottom of the auxiliary component, thereby resetting the auxiliary component to facilitate the support of the extended center rod. At the same time, push rod two will also reset to facilitate the placement of new raw materials above the loading mechanism.

[0020] Compared with the prior art, the present invention provides a forming apparatus and method for seamless titanium alloy tubes for ships, which has the following advantages:

[0021] 1. This invention, by setting up a placement mechanism, drives the raw material to rotate synchronously while extruding and molding it, so that the obstructed part of the raw material in contact with the roller changes continuously, thereby achieving uniform extension and diffusion of the raw material. This avoids the problem of unidirectional excessive extension of the raw material in the traditional extrusion process. After processing, the seamless tube is limited by the baffle and will continue to rotate with the roller on the placement mechanism. The hot rolling process further optimizes the flatness of the outer wall of the tube and improves the finished product effect.

[0022] 2. By setting auxiliary components, the present invention provides multi-point balanced support for the central rod when the equipment pushes it out, effectively avoiding the problem of gravity sagging caused by the long extension of the central rod, preventing radial displacement during processing, ensuring that the central rod remains coaxial with the raw material axis, thereby controlling the centering and positioning of the seamless tube's round hole, ensuring the stability of precision during the tube forming process, and improving the processing quality.

[0023] 3. By setting up a placement mechanism, the present invention simultaneously triggers the support structure of the auxiliary components to unload sequentially during the process of driving the raw material to move and extruding through the central rod. This ensures that the bottom support force of the auxiliary components is dynamically removed as the raw material is pushed, avoiding contact interference between the auxiliary components and the forming raw material, thereby effectively ensuring the smoothness of movement and structural stability of the equipment during continuous processing.

[0024] 4. By setting up roller two, the present invention can clamp and position the top of the raw material during the raw material processing. The upper and lower support constraints formed by roller two and roller one can effectively suppress the radial displacement and shaking of the raw material during the punching process, providing a stable support foundation for punching and subsequent molding processes. From the mechanical positioning level, the position of the raw material during the processing is guaranteed, ensuring the accurate execution of the extrusion molding operation.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] Example 1: See Figures 1-4 The present invention provides a technical solution: a seamless titanium alloy tube forming device for ships, including a base plate 1, a discharge plate 101 fixedly connected to the top of the base plate 1, a roller 1, a roller 2 and a feeding mechanism are provided to ensure the stability of the raw material position, a base 102 fixedly connected to the top of the base plate 1, a pushing device 103 fixedly connected to the top of the base 102, a pushing column 104 fixedly connected to the front end of the pushing device 103, a roller 106 rotatably connected to the inside of the base 102 through a bearing, a feeding mechanism 2 fixedly connected to the top of the base plate 1, a placement mechanism 3 fixedly connected to the top of the base plate 1, a groove 105 opened at the front end of the base 102, a push rod 107 fixedly connected to the top of the base 102, a top plate 108 fixedly connected to the top of the push rod 107, and a roller 2 109 rotatably connected to the inner wall of the top plate 108 through a bearing.

[0040] When the raw material needs to be processed, as the raw material is placed on roller 106, the first pusher 103 is activated to drive the pusher 104 forward. The forward movement of the pusher 104 will push the raw material to the bottom of roller 2 109. At this time, the pusher 107 is activated to drive the top plate 108 downward. The downward movement of the top plate 108 will drive roller 2 109 to press on the top of the raw material. In this way, the position of the raw material will be fixed by roller 106 and roller 2 109. Then, the pusher 104 is activated again to drive the raw material to be squeezed and opened by the placement mechanism 3.

[0041] The feeding mechanism 2 includes: a base 201, the bottom of which is fixedly connected to a base plate 1; a ramp 202 fixedly connected to the top of the base 201; a connecting rod 203 provided on the top of the base 201; the outer wall of the connecting rod 203 fixedly connected to the ramp 202; the ramp 202 has a protruding part near the base 102 to restrict the movement of raw materials; a connecting ring 204 rotatably connected to the outer wall of the connecting rod 203 via a bearing; a right-angle plate 205 fixedly connected to the outer wall of the connecting ring 204; a protruding plate 206 fixedly connected to the top of the right-angle plate 205 to temporarily block the movement of raw materials; a rotating column 207 fixedly connected to the bottom of the right-angle plate 205; and a push rod 208 rotatably connected to the outer wall of the rotating column 207 via a bearing. The bottom of push rod 208 is rotatably connected to base 201 via bearing. Push rod 208 is used to control the deflection angle of right angle plate 205. When preparing to process the raw material, the raw material is first placed on right angle plate 205. The raw material will be blocked by the protruding part of right angle plate 205 and protruding plate 206, preventing the raw material from moving downward. Then, push rod 208 is activated to pull rotating column 207 downward. The downward moving rotating column 207 will cause right angle plate 205 to deflect. The deflected right angle plate 205 will make protruding plate 206 no longer block the raw material, thus allowing the raw material to move downward along the trajectory of ramp plate 202. Since the end of ramp plate 202 away from base 201 has a protrusion, the raw material can be stably stopped above roller 106.

[0042] Example 2: To ensure the forming effect of the equipment on seamless steel pipes, a placement mechanism 3 and an auxiliary component 31 are provided. Please refer to [link / reference]. Figures 5-9Based on Embodiment 1, the present invention provides a technical solution: the placement mechanism 3 includes a base plate 301, a side plate 302 fixedly connected to the top of the base plate 301, a roller 303 rotatably connected to the inner wall of the top of the side plate 302 via a bearing, a motor 304 fixedly connected to the outer wall of the side plate 302, the output end of the motor 304 fixedly connected to the roller 303, a pushing device 306 fixedly connected to the top of the base plate 301, and sliding grooves 305 on both sides of the bottom of the pushing device 306. A central rod 307 is fixedly connected to one side of the side plate 302, a baffle 308 is fixedly connected to the top of the side plate 302, a track 3010 is fixedly connected to the top of the bottom plate 301, and an auxiliary component 31 is fixedly connected to the top of the bottom plate 301. The central rod 307 is used to extrude the raw material. A push rod 309 is fixedly connected to the top of the bottom plate 301. A right-angle plate 3011 is fixedly connected to the end of the push rod 309 near the pushing device 306, and a connecting post 30 is fixedly connected to the end of the right-angle plate 3011 away from the push rod 309. 12. The outer wall of the connecting column 3012 is movably connected to the slide 305. A movable plate 3013 is fixedly connected to the outer wall of the connecting column 3012. The bottom of the movable plate 3013 is movably connected to the track 3010. A protruding plate 3014 is fixedly connected to the top of the movable plate 3013. The protruding plate 3014 controls the height of the auxiliary component 31 by extrusion. When the equipment is in use, the center rod 307 is pushed out by the pushing device 306. Then, under the push of the pushing column 104, the raw material is squeezed against the center rod 307. Simultaneously, the motor 304 is started to drive the roller 303 to rotate. In this way, during the process of the raw material being squeezed, the rotation of the roller 303 will drive the raw material to rotate together. In this process, the push rod 309 will be activated to drive the right angle plate 2 3011 to move. The moving right angle plate 2 3011 will change the position of the protruding plate 2 3014 through the connecting column 3012 and the movable plate 1 3013. Since the position of the protruding plate 2 3014 moves backward, the bottom of the auxiliary component 31 will lose support, which will prevent the auxiliary component 31 from contacting the raw material.

[0043] The auxiliary component 31 includes a sliding column 311, a movable plate 312 on the top of the sliding column 311, a circular hole 313 at the bottom of the movable plate 312, the inner wall of the circular hole 313 being movably connected to the sliding column 311, and a force roller 314 being rotatably connected to the outer wall of the movable plate 312 via a bearing. A spring 315 is fitted on the outer wall of the circular hole 313, the top of the spring 315 being fixedly connected to the movable plate 312, and the bottom of the spring 315 being fixedly connected to the base plate 301. The movable plate 312 is used to support the center rod 307 before the raw material moves above the roller 303. As the protruding plate 3014 moves backward, the bottom of the force roller 314 loses the support of the protruding plate 3014. At this time, the movable plate 312 will retract and move downward under the elastic force of the spring 315 to avoid contact between the movable plate 312 and the raw material.

[0044] A method for forming seamless titanium alloy tubes for shipbuilding includes the following steps:

[0045] S1. When the raw material needs to be processed into a seamless tube, the raw material needs to be heated first. Then, the heated raw material is placed above the right angle plate 205. After it is placed above the right angle plate 205, the push rod 208 is activated to drive the right angle plate 205 to deflect downward. The deflected right angle plate 205 will make the protrusion plate 206 no longer able to block the downward movement of the raw material. The push from behind the right angle plate 205 will drive the raw material to fall onto the roller 106 along the trajectory of the ramp plate 202.

[0046] S2. After the raw material is placed on roller 106, push rod 107 is activated to lower the top plate 108, and roller 2 109 presses down on the raw material to clamp and fix it, ensuring that the raw material will not shift during processing. Then, push device 2 306 is activated to push out the center rod 307. After that, push device 1 103 is activated to push push column 104 forward. The moving push column 104 will push the raw material forward. At this time, the raw material is pressed and contacted by the center rod 307 under the push of push column 104. Under the pressure of the center rod 307, a hole is opened in the center of the raw material. While the raw material is pushed forward, push rod 309 will drive the protruding plate 2 3014 to move forward along the track 3010. As the protruding plate 2 3014 moves forward along the track 3010, the protruding plate 2 3014 no longer presses the auxiliary component 31, and the height of the auxiliary component 31 is reduced to avoid affecting the movement of the raw material.

[0047] S3. When the equipment processes the raw material, the motor 304 drives the roller 303 to rotate. The rotating roller 303 will drive the raw material to rotate together, so as to prevent the compressed raw material from moving in one direction and affecting the shape of the seamless tube. After the processing of the raw material is completed, the center rod 307 is retracted by the push device 2 306. Due to the obstruction of the baffle 308, the processed raw material will continue to remain on the roller 303. At this time, the roller 303 will continue to rotate to further process the surface of the seamless tube. After the processing is completed, the operator pushes the seamless tube out of the equipment with tools.

[0048] S4. After the processed seamless tube is pushed out from above the placement mechanism 3, the second pusher 306 and the first pusher 103 are activated to retract the center rod 307 and the pusher column 104 to facilitate the subsequent loading of raw materials. Then, the third pusher 309 is activated to drive the first movable plate 3013 to reset. As the first movable plate 3013 resets, the second protrusion 3014 will be placed back at the bottom of the auxiliary component 31, thereby resetting the auxiliary component 31 to facilitate the support of the extended center rod 307. At the same time, the second pusher 208 will also reset to facilitate the placement of new raw materials above the loading mechanism 2.

2. A forming method using the seamless titanium alloy tube forming apparatus for ships as described in claim 1, comprising the following steps: S1. When the raw material needs to be processed into a seamless tube, the raw material needs to be heated first, and then the heated raw material is placed on the right angle plate one (205). After it is placed on the right angle plate one (205), the push rod two (208) is activated to drive the right angle plate one (205) to deflect downward. The deflected right angle plate one (205) will make the protrusion plate one (206) unable to block the downward movement of the raw material. And through the push behind the right angle plate one (205), the raw material is driven to fall on the roller one (106) along the trajectory of the ramp plate (202). S2. After the raw material is placed on roller one (106), push rod one (107) is activated to drive the top plate (108) to descend, and then roller two (109) presses down on the raw material to clamp and fix it, ensuring that the raw material will not shift during processing. Then push device two (306) is activated to push out the center rod (307). After that, push device one (103) is activated to drive the push column (104) forward. The moving push column (104) will push the raw material forward. At this time, the raw material is on the push column (109). Under the push of 104), it presses against the center rod (307). Under the pressure of the center rod (307), it makes a hole in the center of the raw material. While the raw material is pushed forward, the push rod three (309) will drive the second protruding plate (3014) to move forward along the track (3010). As the second protruding plate (3014) moves forward along the track (3010), the second protruding plate (3014) no longer presses against the auxiliary component (31). The height of the auxiliary component (31) then decreases to avoid affecting the movement of the raw material. S3. When the equipment processes the raw material, the motor (304) drives the roller three (303) to rotate. The rotating roller three (303) will drive the raw material to rotate together, so that the raw material that is squeezed will move in one direction and affect the shape of the seamless tube. After the processing of the raw material is completed, the center rod (307) is retracted by pushing device two (306). Due to the obstruction of the baffle (308), the processed raw material will continue to remain on the roller three (303). At this time, the roller three (303) will continue to rotate to further process the surface of the seamless tube. After the processing is completed, the operator pushes the seamless tube out of the equipment with tools. S4. After the processed seamless tube is pushed out from above the placement mechanism (3), the second pusher (306) and the first pusher (103) are activated to retract the center rod (307) and the pusher column (104) to facilitate the subsequent loading of raw materials. Then, the third pusher (309) is activated to drive the first movable plate (3013) to reset. As the first movable plate (3013) is reset, the second protrusion (3014) will be placed at the bottom of the auxiliary component (31) again, thereby allowing the auxiliary component (31) to reset, which facilitates the support of the extended center rod (307). At the same time, the second pusher (208) will also reset to facilitate the placement of new raw materials above the loading mechanism (2).
